Description

  The present invention relates to a vehicle seat device, and more particularly to a vehicle seat device capable of attaching an infant seat.

  In order to seat an infant on a vehicle seat that is pre-installed in the vehicle, an infant seat equipped with an infant-specific restraining device is commercially available. In consideration of safety, such an infant seat is preferably attached to the second row seat (or the rear seat) rather than the front row seat of the vehicle.

  The second row seat is generally configured in the form of a so-called bench seat having a seating surface continuous in the vehicle width direction. When attaching an infant seat to such a second row seat, for example, when one adult and one infant get on the vehicle, it is easy for the adult to take care of the infant while stopping from the driver's seat. There is a need to attach the infant seat near the center of the second row seat. This is because for an adult seated in the driver's seat, there is a space between the driver's seat and the passenger seat, so that the infant seated on the infant seat can be easily confirmed from the space. A configuration in which an infant seat can be fixed in the vicinity of the center of the bench seat is disclosed in Patent Document 1 as an example.

JP-A-6-270729

  On the other hand, in recent years, the structure of the vehicle seat side that is originally arranged in the vehicle and the retrofit are aimed at unifying the installation work method when attaching the infant seat to the vehicle seat and preventing the user's erroneous installation. The structure of the infant seat side to be used and its mounting method are standardized between the automobile manufacturer and the infant seat manufacturer. What is referred to as ISO-FIX is such a standard, and a pair of lower anchors formed at a predetermined (specified) interval in the gap between the seat back and the seat cushion on the vehicle seat side are provided, It is provided that a lock that can be engaged with the lower anchor is provided on the infant seat side. Therefore, the infant seat compliant with ISO-FIX is fixed to the vehicle seat compliant with ISO-FIX by engaging the lock with the lower anchor.

  On the other hand, it is also known that the second row seat is divided into two or three so as to be continuous in the vehicle width direction. By adopting such a configuration, it is possible to arrange such that the respective divided portions independently fall down on the corresponding seat back or slide in the front-rear direction. When divided into three, the case where two adults sit side by side is considered to be the most frequent, so both sides are designed with priority, so the center is narrower than both sides It tends to be a neighbor.

  In such a case, if it is possible to attach an infant seat compliant with ISO-FIX to the center part of the second row seat divided into three so that the width of both side parts is relatively wide and the center part becomes narrower, Due to the prescribed distance between the pair of lower anchors, it is difficult to provide a pair of lower anchors at the center portion of the second row seat, and it is necessary to provide a pair of lower anchors on both divided sides. Arise. In addition, when both side portions of the second row seat are configured to be slidable in the front-rear direction, it is necessary to align at least the both side portions at the same front-rear direction position in order to attach the child seat. When attached, there is a problem that the position of the second row sheet, particularly both side portions when divided into three, is restricted. This problem is not limited to the combination of so-called ISO-FIX vehicle seats and infant seats, but a pair of lower anchors and infant seats are attached via locks provided for the infant seats. In the case of the type, the same occurs when the width of the central seat is narrower than the interval between the locks on the infant seat side. The configuration described in Patent Document 1 is not a divided second-row sheet in the first place, the underlying technology is different, and there is no mention or suggestion of the above-mentioned needs or problems.

  The present invention has been made in view of the above points, and the problem is that the central portion of the second row sheet divided into three so that the width of both side portions is relatively wide and the central portion becomes narrower. In addition, it is to realize a structure capable of fixing the infant seat.

  In order to solve the above problems, the present invention has the following configuration. That is, the first configuration of the present invention is for a vehicle that includes a seat row that includes a plurality of seats that are provided in the vehicle interior of the vehicle and arranged adjacent to each other in the vehicle width direction, and to which an infant seat can be attached. A seat device, wherein the row of seats has a first seat, a length in the vehicle width direction longer than the first seat, and the first seat on both sides in the vehicle width direction of the first seat. A pair of second sheets arranged adjacent to each other, wherein the first sheet is configured to protrude from both side portions of the first sheet and to be accommodated inside the both side portions; An anchor member that can be engaged with a pair of locks provided on the infant seat when protruding from both sides of the first seat, and the seat surface is substantially continuous with the seat surface of the second seat; The first position and the anchor member is the first position And it is characterized in that it is movable in and a second position to be projectable from both sides of the sheet.

  According to the above configuration, the infant seat is attached to the center first seat that is shorter in the vehicle width direction than the second seats arranged on both sides adjacent to each other in the vehicle width direction so as to protrude from both sides. Since the first seat is movable to a position where the anchor member can protrude, the width of the first seat is larger than the distance between the pair of locks provided on the infant seat. Even when the child seat is small, the anchor member can be protruded by appropriately moving to the second position when attaching the child seat, and the child seat lock can be engaged with the anchor member. . In this case, since the infant seat is fixed only to the first seat, even when the infant seat is attached, for example, the rearward slide of each second seat and the seat back angle are independent. Adjustments can be made.

  According to a second configuration of the present invention, the seat row is a second row among a plurality of seat rows provided in a vehicle interior of the vehicle or a seat row behind the second row. The second position is a position relatively forward with respect to the second seat.

  According to said structure, when the 1st sheet | seat exists in the position ahead relatively with respect to the 2nd sheet | seat, the attachment of the infant seat with respect to a 1st sheet | seat is attained. Therefore, the infant seat is positioned relatively forward, and the infant seat is closer to the adult seated in the front seat row than the first seat to which the infant seat is attached. It is possible to easily check and care for the infant seated on the seat.

  According to a third configuration of the present invention, the anchor member is configured to be restricted from projecting from both sides of the first sheet when the first sheet is in the first position. It is a feature.

  According to said structure, when a 1st sheet | seat exists in a 2nd position, an anchor member cannot protrude from the both sides of a 1st sheet | seat. Therefore, the anchor member can be prevented from interfering with and being damaged by the adjacent second sheet.

  A fourth configuration of the present invention is configured such that the movement of the first sheet from the second position to the first position is restricted when the anchor member is in a protruding state. It is characterized by being.

  According to the above configuration, the first sheet cannot move to the first position, that is, the position adjacent to the second sheet, in a state where the anchor member protrudes. Accordingly, it is possible to prevent the anchor member from being damaged by the interference of the anchor member with the second sheet by the movement of the first sheet while the anchor member is protruding.

According to a fifth configuration of the present invention, the anchor member is configured to be at a position higher than the seating surface of the second seat regardless of the position of the first seat. Is.

  According to said structure, since the position of an anchor member is always offset upwards with respect to the seat surface of a 2nd sheet | seat, an anchor member can be used only by making a 1st sheet | seat movable to the front-back direction. It becomes a state. Therefore, the first to fourth configurations can be realized only by using a conventional mechanism for sliding the seat back and forth.

  According to the present invention, a structure is realized in which the infant seat can be fixed to the central portion of the second row seat divided into three so that the width of both side portions is relatively wide and the central portion is narrower. I can do it.

  The best mode for carrying out the present invention will be described below with reference to FIGS. First, a first embodiment of the present invention will be described with reference to FIGS.

  FIG. 1 shows a seat row Sr of a vehicle seat to which the present invention is applied. In the present embodiment, a plurality of seat rows are provided in the vehicle interior of the vehicle, and the seat row Sr is a second row seat Sr disposed behind the first row seat that defines the driver seat and the passenger seat. is there.

  The second row seat 2 is divided into three in the vehicle width direction, and is composed of both side seats 1 having a relatively large width direction length and a center seat 2 having a relatively small length in the width direction. It is possible to fall forward independently. So, by laying down each seat back part forward, it can be arranged so that the back of the seat back part can be used as a floor for a table or a luggage compartment. The reason why the width of the both side seats 1 is relatively wide and the width of the central seat 2 is set to be relatively small is considered to be the most frequent situation where two adults are seated side by side as the usage form of the second row seat Sr. This is because the double-sided seat 1 has a large width so that one adult can sit comfortably. Note that the both side seats 1 may be slidable in the front-rear direction independently.

  As shown in FIG. 1 (a), the center seat 2 has a seat surface where the seat surfaces of both side seats 1 are substantially continuous (hereinafter referred to as a rear position), and as shown in FIG. 1 (b), It is comprised so that it can be moved between the positions ahead of the both-side seats 1 (hereinafter referred to as front positions). Although details will be described later, when the center seat 2 is in the forward position, the lower anchor 40 is configured to be able to protrude from both sides so that the infant seat can be attached in a form conforming to so-called ISO-FIX. (In FIG. 1 (b), only the left side in the vehicle traveling direction is shown, but the lower anchor 40 projects in the same manner on the right side). That is, the center seat 2 has a vehicle width direction length shorter than the distance between the pair of lower anchors 40 defined by ISO-FIX, but the lower anchor 40 can protrude from both sides by moving to the front position. It is possible to attach an infant seat compliant with the standard.

  Below, the structure including the protrusion mechanism of the lower anchor 40 in the center sheet | seat 2 is demonstrated, referring FIG. 2 thru | or FIG. Since both side sheets 1 have a well-known sheet structure, detailed description thereof is omitted.

  FIG. 2 is an exploded perspective view of the central sheet 2. As shown in the figure, the central seat 2 is mainly composed of a cushion frame 20, a back frame 21, a slide mechanism 22, a lower anchor assembly 4, and a slide position transmission mechanism 3. A back frame 21 is rotatably supported near the rear portion of the cushion frame 20. The cushion frame 20 is supported by the vehicle body via a slide mechanism 22, and is slidable in the front-rear direction of the vehicle. Such a configuration is the same as that of a known sheet apparatus. Although the cushion frame 20 and the back frame 21 are covered with a cushion material, illustration of the cushion material is omitted.

  On the other hand, the lower anchor assembly 4 is attached in the vicinity of the rear portion of the cushion frame 20. The lower anchor assembly 4, which will be described in detail later, is an assembly including a lower anchor 40 that can project and retract in the vehicle width direction, and a pair of left and right arms 41 (not shown in FIG. 2) each provided with the lower anchor 40. The main part 42 is configured mainly by a main body part 42 for receiving them and an operation part 43 provided on the main body part 42 for projecting and storing the pair of arms 41. The operation portion 43 is exposed to the rear portion of the seat cushion even when the central seat 2 is assembled and a cushion material or the like is attached, and can be operated by the occupant.

  A slide position transmission mechanism 3 is provided between the lower anchor assembly 4 and the slide mechanism 22. The slide position transmission mechanism 3 allows or restricts the operation of the operation portion 43 of the lower anchor assembly 4 according to the position of the center seat 2, and the structure and operation thereof will be described in detail later.

  Next, the configuration of the lower anchor assembly 4 will be described with reference to FIG. 3 which is an exploded perspective view of the lower anchor assembly 4. In the following description, “front” indicates a direction corresponding to the front of the vehicle when the lower anchor assembly 4 is attached to the seat, and “rear” indicates a direction corresponding to the rear of the vehicle in the same state. Shall.

  As shown in FIG. 3, the lower anchor assembly 4 includes a pair of left and right arms 41 each provided with a lower anchor 40, a main body 42 that slidably receives the arms 41 in the longitudinal direction thereof, and a rotatable main body 42. As will be described later, the operation unit 43 mainly includes an operation unit 43 that protrudes from the main body 42 and accommodates the arm 41 in the main body 42 by the rotation operation. A lower anchor 40 is provided near one end of the arm 41 so as to protrude forward. The lower anchor 40 engages with a lock portion of an infant seat compliant with so-called ISO-FIX. On the other hand, the front side surface of the main body 42 is formed with notches 44 from both sides from both ends toward the center in the longitudinal direction.When the arm 41 protrudes and retracts, the lower anchor 40 is located inside the notch 44. Moving. Further, a notch 45 is formed from both sides toward the longitudinal center from both ends of the rear side surface of the main body 42, and a rod 46 described later is provided on the rear side surface of the arm 41. A mounting portion (not shown) moves inside the notch 45.

  In the vicinity of the central portion in the longitudinal direction on the rear side surface of the main body 42, an operation unit 43 is rotatably attached. A bar 430 is fixed to the operation unit 43 so as to pass through the rotation shaft of the operation unit 43. That is, the bar 430 is also integrally rotated by the rotation of the operation unit 43.

  Rods 46 are provided between both ends of the bar 430 and the left and right arms 41, respectively. One end of the rod 46 is attached to the end of the bar 430 fixed to the operation unit 43, and the other end is attached to the rear surface of the arm 41. That is, when the bar 430 is rotated by the rotation of the operation unit 43, the rod 46 is displaced by the displacement of the end of the bar 430, and as a result, the arm 41 moves while being guided in the longitudinal direction by the main body 42. Become.

  The protrusion and storage operation of the arm 41 due to the turning operation of the operation unit 43 in the above configuration will be described with reference to FIGS. 4 (a) and 4 (b). 4A is a schematic view seen from the front of the vehicle when the arm 41 is in the retracted state, and FIG. 4B is a schematic view seen from the front when the arm 41 is in the protruding state.

  As shown in FIG. 4A, when the arm 41 is in the retracted state, the bar 430 is oriented in a substantially vertical direction. That is, the rod 46 is pulled inwardly by the arm 41 to the maximum, and the left and right arms 41 are located inside the main body 42. On the other hand, as shown in FIG. 4B, when the arm 41 is in the protruding state, the bar 430 is rotated by a slight angle in the direction of the arrow A, and both ends of the bar 430 are rotated by the operation unit 43. It is in a state of being displaced on both sides in the longitudinal direction with respect to the shaft. That is, the rod 46 is pushed out to both sides in the longitudinal direction, and the left and right arms 41 protrude from the main body 42, respectively. As is clear from the above description, when the arm 41 is in the retracted state, the lower anchor 40 is positioned on the inner side of both sides of the central seat 2 and when the arm 41 is in the protruding state, the lower anchor 40 is positioned on the central seat 2. Projects outward from both sides.

The rotation of the operation unit 43 is regulated so that the arm 41 protrudes on both sides and the distance between the left and right lower anchors 40 does not exceed a state defined by ISO-FIX. It is possible to attach an infant seat compliant with ISO-FIX as it is by rotating the operation unit 43 to the maximum extent that it can rotate when protruding. In addition, when the infant seat can be attached to the center seat 1, the center seat 2 is positioned in front of the both side seats 1, so that the passenger seated on the seat in front of the second row seat Sr is Since the infant seat is close to the infant seat, the infant seated on the infant seat can be easily taken care of.

  In this embodiment, in addition to the above configuration, the protruding operation of the arm 41, that is, the lower anchor 40, is configured to be regulated by the slide position of the central seat 2. Hereinafter, such a configuration will be described with reference to FIGS. 2, 3, 5, and 6.

  Referring to FIG. 2 again, the central seat 2 can be moved in the front-rear direction by a slide mechanism 22 provided between the lower portion of the seat and the vehicle floor. As is well known, the slide mechanism 22 includes a lower rail 221 provided on the floor of the vehicle and an upper rail 220 provided below the seat cushion of the central seat 2 and slidably guided by the lower rail 221 (see FIG. In FIG. 2, the reference symbols of the upper rail 220 and the lower rail 221 are omitted).

  As described above, the slide position transmission mechanism 3 is provided between the slide mechanism 22 and the lower anchor assembly 4. Although not shown in FIG. 2, the slide position transmission mechanism 3 has a wire cable 30, one end of the wire cable 30 fixed thereto, a lever 31 pivotally supported at a predetermined position of the lower rail 221, and the other end of the wire cable 30. The engaging portion 32 is fixed and pivotally supported by the main body portion 42.

  The configuration of the lever 31 is shown in FIG. 5, which is a schematic view of the vicinity of the position of the slide mechanism 22 where the lever 31 is provided. 5A shows a state in which the upper rail 220 is located rearward, that is, the center seat 2 is in the rear position, and FIG. 5B shows a state in which the upper rail 220 is located forward, ie, the central seat 2 is in the front position. Indicates the state. Moreover, FIG.5 (c) is BB arrow sectional drawing of Fig.5 (a).

  As optimally shown in FIG. 5 (c), a bracket 310 is provided on the lower surface of the lower rail 221, and the lever 31 is rotatable on the bracket 310 within a plane including the longitudinal direction of the slide mechanism 22. It is pivotally supported. Further, the wire cable 30 is always urged in the pulling direction toward the lower anchor assembly 4 at a position where the wire cable 30 is attached to the lower anchor assembly 4 described later. That is, when the upper rail 220 is in the rear position, that is, when the central seat 2 is in the rear position, as shown in FIG. 5A, the wire cable 30 is biased in the pulling direction as described above. The upper end of the lever 31 is in contact with the flange on the upper edge of the lower rail 220. On the other hand, when the center seat 2 moves forward from the state shown in FIG. 5A, the front end of the upper rail 220 pushes down the lever 31 forward and rotates in the direction of arrow C (this state is shown in FIG. 5). The state shown in (b)), the wire cable 30 is pulled toward the slide mechanism 22 side.

  On the other hand, the end of the wire cable 30 on the lower anchor assembly 4 side is connected to the engaging portion 32 as shown in FIG. The engaging portion 32 is pivotally supported on the upper surface of the main body portion 42 and is connected to the wire cable 30 at one end. The shaft support 320 is provided with a spring (not shown), and the engaging portion 32 urges the wire cable 30 to pull in the direction of the lower anchor assembly 4. Further, the other end portion of the engaging portion 32 engages with the bar 430 fixed to the operating portion 43 in a state where the wire cable 30 is pulled in the direction of the lower anchor assembly 4 and protrudes the lower anchor 30 of the operating portion 43. In the state where the turning operation in the direction to be moved is restricted and the wire cable 30 is pulled in the direction of the slide mechanism 22, the engagement with the bar 430 is released by turning around the shaft support portion 320.

  That is, the wire cable 30 is pulled toward the lower anchor assembly 4 as shown in FIG. 6 which is a top view in the vicinity of the portion where the engaging portion 32 of the lower anchor assembly 4 is pivotally supported (FIG. 6A). 2), the other end of the engaging portion 32 is in contact with the bar 430, and the bar 430 cannot rotate in the direction in which the arm 41 protrudes. On the other hand, in the state where the wire cable 30 is pulled toward the slide mechanism 22 (the state shown in FIG. 6B), the engaging portion 32 is rotated in the direction of arrow D by the wire cable 30 to engage with the bar 430. The combination is released, and the bar 430 can be rotated in the direction in which the arm 41 protrudes.

  Thus, when the central seat 2 is in the rear position, the wire cable 30 is pulled toward the lower anchor assembly 4 by the engaging portion 32 attached to the lower anchor assembly 4 and biased by the spring, as shown in FIG. In addition, the engaging portion 32 is in a position where the rotation of the bar 430 is restricted as shown in FIG. 6 (a). When the central seat 2 is moved to the front position from this state, the lever 31 is rotated by the movement of the upper rail 220 and the wire cable 30 is pulled toward the slide mechanism 22 as shown in FIG. As shown in FIG. 6B, 32 is disengaged from the bar 430 so that the bar 430, that is, the operation portion 43 can be rotated. In other words, the arm 41 cannot protrude when the central seat 2 is in the rear position adjacent to the both side seats 1, and in such a state, the arm 41 and the lower anchor 40 interfere with the adjacent both side seats 1 and are damaged. Is prevented.

  In the above embodiment, when the central seat 2 is in the rear position, the operation of the operation unit 43 is restricted so that the lower anchor 40 does not protrude left and right. However, the arm 41, that is, the lower anchor 40 protrudes left and right. In this case, it is possible to prevent the arm 41 from being damaged by restricting the sliding of the central seat 2 to the rear position. Such a configuration will be described below as a second embodiment of the present invention.

  Since the cushion frame 20, the back frame 21, the cushion material (not shown), the slide mechanism 22, and the lower anchor assembly 4 constituting the central seat 2 are the same as those in the first embodiment, the first embodiment. The same reference numerals are assigned and detailed description is omitted. Hereinafter, the slide control mechanism 5 which is a feature of the second embodiment will be described in detail.

  The slide control mechanism 5 is provided between the slide mechanism 22 and the lower anchor assembly 4. As will be described in detail below, the wire cable 50 and one end of the wire cable 50 are fixed and the main body portion. The transmission portion 51 is pivotally supported by 42, and the other end of the wire cable 50 is fixed, and the stopper 52 is pivotally supported at a predetermined position of the lower rail 221.

  As shown in FIG. 7, which is an exploded perspective view of the lower anchor assembly 4 according to the second embodiment, the end of the wire cable 50 on the lower anchor assembly 4 side is connected to the transmission portion 51. The transmission portion 51 is pivotally supported on the upper surface of the main body portion 42 and is connected to the wire cable 50 at one end portion. The wire cable 50 is always pulled and biased toward the slide mechanism 22 as described later. Further, the other end of the transmission unit 51 is in contact with the bar 430 of the operation unit 43.

  The other end of the transmission unit 51 is pushed and moved by the rotation of the bar 430 accompanying the rotation operation of the operation unit 43 to rotate the transmission unit 51. That is, as shown in FIG. 8 which is a top view of the vicinity where the transmission portion 51 of the lower anchor assembly 4 is pivotally supported, the bar 430 is in a substantially vertical direction (that is, a state in which the arm 41 is accommodated) ( In the state where the arm 41 is rotated (the state shown in FIG. 8B) as opposed to the state shown in FIG. It is moved and rotated in the direction of arrow E by a predetermined angle. By the rotation of the transmission portion 51, the wire cable 50 connected to one end of the transmission portion 51 is pulled toward the lower anchor assembly 4 side.

  On the other hand, the other end of the wire cable 50 is coupled to a stopper 52 that is pivotally supported at a predetermined position of the lower rail 221. The configuration of the stopper 52 is shown in FIG. 9, which is a schematic view of the vicinity of the position where the stopper 52 of the slide mechanism 22 is provided. 9A shows a state where the upper rail 220 is positioned forward, that is, a state where the central seat 2 is positioned forward, FIG. 9B shows a state where the rearward sliding of the upper rail 220 is restricted by the stopper 52, FIG. 9 (c) is a cross-sectional view taken along line FF in FIG. 9 (b).

  As optimally shown in FIG. 9C, a bracket 520 is provided on the lower surface of the lower rail 221, and a stopper 52 can be rotated on the bracket 520 in a plane including the longitudinal direction of the slide mechanism 22. The shaft is supported by the shaft support portion 521. The stopper 52 is curved toward the upper rail 220 side. Further, the shaft support portion 521 is provided with a spring (not shown) and urges the wire cable 50 in the direction of pulling the wire cable 50 toward the slide mechanism 22 side. That is, when the bar 430 is in a substantially vertical direction (the lower anchor 40 is stored), the stopper 52 is retracted from the slide track of the upper rail 220 as shown in FIG. Allow sliding into. On the other hand, in a state where the bar 430 is rotated by the operation of the operation unit 43 and the transmission unit 51 of the lower anchor assembly 4 is pushed and moved, the wire 52 is pulled toward the lower anchor assembly 4 and the stopper 52 is moved to the arrow F. Since the end of the upper rail 220 overlaps with the slide track of the upper rail 220, the upper rail 220 abuts against the stopper 52 as shown in FIG.

  In addition, as a structure common to 1st Embodiment and 2nd Embodiment, the position where the lower anchor assembly 4 is attached to the cushion frame 20 is set to the left and right arms at a position higher than the height of the seat cushion seat surface of the both side seats 1. If the height 41 and the lower anchor 40 protrude from each other, the lower anchor 40 can be used only by moving the central seat 2 forward through the slide mechanism 22. Moreover, you may combine 1st Embodiment and 2nd Embodiment. In the first and second embodiments, the lower anchor 40 can be used by sliding the central seat 2 back and forth. The left and right arms 41 and the lower anchor 40 can be brought into a projectable state by moving the left and right arms 41. Furthermore, the present invention is not limited to the lower anchor 40 and the infant seat compliant with ISO-FIX, but a type in which the infant seat is attached via a pair of lower anchors and a lock provided corresponding to the infant seat. This can be applied to the case where the width of the central seat is narrower than the lock interval on the infant seat side.
