Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
In this embodiment, a striker that supports a vehicle seat provided on a rear seat of a passenger car will be described as an example of the striker of the present invention. First, a vehicle seat supported by a striker will be briefly described.

  Vehicle seats 1 </ b> R and 1 </ b> L shown in FIG. 1 are rear seats of the vehicle 2. The rear seat is divided into two parts in the left-right direction of the vehicle 2 and is adjacent to each other. After the seat B, for example, the backrest B1 of the right vehicle seat 1R is tilted forward, the seat C1 is raised forward. It is possible. (This operation is referred to as “tumble”. See also FIG. 3.) By tumbling the right vehicle seat 1R in this way, a long storage space S in the front and rear direction can be secured on the rear right side of the vehicle. In addition, the vehicle seat 1L corresponding to the left rear seat can be tumbled so that a long storage space in the front and rear can be secured on the left side of the vehicle rear.

  In the present specification, front, rear, left and right are based on an occupant sitting on the vehicle seats 1R, 1L. Further, the symbols R and L are used in addition to the numerical symbols as meaning the right and left, respectively.

  Each of the left and right vehicle seats 1R, 1L has a pair of mounting brackets 60 arranged on the left and right of the front portion of the seating portion C1, and as shown in FIG. 2 and FIG. Further, the vehicle body side bracket 61 fixed to the floor surface 3 (vehicle body floor) is supported so as to be able to rotate back and forth.

  As shown in FIG. 2, the seat frame 10 of the vehicle seat 1 </ b> R includes a cushion frame 11, a seat back frame 12, and a pair of left and right slide rails 13 provided on the left and right, as in the known seat frame, and is not illustrated. The seat back frame 12 can be displaced from the seating state shown in FIG. 2 to a state where it is tilted forward (not shown) by a reclining mechanism or the like. Further, rear brackets 15L and 15R are provided at the rear portions of the front and rear slide rails 13, respectively. As shown in FIG. 4, each of the rear brackets 15L and 15R has a lock mechanism 90 (only the right lock mechanism 90R). (Shown) is provided.

  The lock mechanism 90 includes a hook-shaped lock arm 91 and a base 92 that supports the lock arm 91 so as to be swingable. The base 92 is opposed to the inner peripheral surface of the lock arm 91, thereby forming a connection hole 93 connected to the striker 98 described later. The lock arm 91 is urged to a normally closed position (position where the connection hole 93 is formed) by a spring (not shown), and is separated from the base portion 92 by a lock release mechanism using a known wire, thereby connecting the connection hole 93. Is opened so as to be detached from the striker 98. When the lock arm 91 is removed from the striker 98 in this way, the cushion frame 11 and the seat back frame 12 can be tumbled forward.

  As shown in FIG. 4, the striker 98R on the right side (outside in the left-right direction) of the seat frame 10 is arranged on the floor surface 3, so that the striker 98L on the left side (inside in the left-right direction) is also arranged on the floor surface 3. (See FIG. 2).

  As a result, when a force acting toward the right side (outward in the left-right direction) acts on the seat frame 10 and there is no object that impedes movement with respect to the outside of the vehicle body, the connecting portion 220 (see FIG. 5)), the lock mechanism 90R may be displaced, resulting in looseness and noise / noise. Therefore, in this embodiment, the position of the lock mechanism 90R with respect to the connecting portion 220 (see FIG. 5) of the right striker 98R is provided by providing the position shift preventing member 100 as an example of the position shift preventing portion only on the right striker 98R. Misalignment (specifically, movement to the position of the bent upper end portion 211 of the rod portion 210 shown in FIG. 5) is prevented. In the present embodiment, the misalignment prevention member 100 is provided only on the right striker 98R. However, the present invention is not limited to this, and at least one of the left and right strikers that support the vehicle seat (outside the vehicle body). It may be provided in the one arranged in the above). Moreover, if it is provided on both the left and right strikers, it is possible to prevent misalignment on both sides, and more stable holding is possible.

  Specifically, as shown in FIG. 5A, the right striker 98 </ b> R includes a loop portion 200, a base plate 300, and a misalignment prevention member 100. The left striker 98L differs from the right striker 98R only in that the misalignment prevention member 100 is not provided, and the other structures are substantially the same.

  The loop portion 200 is formed in a U-shape, and mainly has two cylindrical rod portions 210 that are arranged side by side in the left-right direction of the vehicle 2 and extend in the up-down direction, and extend in the left-right direction of the vehicle 2. And a columnar connecting portion 220 for connecting the upper end portion 211 (tip portion) of each rod portion 210. The above-described lock mechanism 90R can be connected to the connecting portion 220.

  The base plate 300 is a substantially rectangular flat plate-like member, and is formed with a bulging portion 310 that bulges upward along one of the two diagonal lines, and sandwiches the bulging portion 310. Two mounting holes 320 are formed side by side on the other diagonal line. Both end portions 201 of the loop portion 200 are fixed to both end portions of the bulging portion 310 by a method such as welding or screwing. The base plate 300 is fixed to the floor surface 3 by bolts (not shown) passed through the mounting holes 320.

  The misalignment prevention member 100 is a flat plate member that is formed separately from the loop portion 200, and is located on the inner side (left and right direction) of the right (right and left direction) rod portion 210R of the two left and right rod portions 210. (Inside). Specifically, the misalignment prevention member 100 is formed on a flat plate-like main body 110 that is orthogonal to the left-right direction, a flange 120 that is bent rightward from the front and rear ends of the main body 110, and a lower side of each flange 120. The mounting portion 130 is fixed to the base plate 300 by welding or the like.

  The main body 110 is a portion with which the lock mechanism 90 </ b> R comes into contact, and has a high rigidity due to the bending of the flange portion 120. At the center of the upper edge of the main body 110, a notch 111 into which the connecting part 220 enters is provided. Thereby, since the part of the misalignment prevention member 100 can be arranged not only on the lower side of the connecting portion 220 but also on the front and rear, a large contact surface between the main body portion 110 and the lock mechanism 90R is secured. .

Next, the operation of the right striker 98R will be described.
For example, when a child seat is attached to the right vehicle seat 1R (see FIG. 1), a lateral force may be applied to the vehicle seat 1R. When a rightward force is applied to the right vehicle seat 1R, the right lock mechanism 90R moves to the right along the connecting portion 220 as shown in FIG. 5B. Before 90R reaches the upper end portion 211 of the right rod portion 210R, it contacts the misalignment prevention member 100. Thereby, the positional displacement of the lock mechanism 90R such that the connecting hole 93 of the lock mechanism 90R moves to the corner of the loop portion 200 (the upper end portion 211 of the rod portion 210R) is prevented.

  Further, when a leftward force is applied to the right vehicle seat 1R, the movement is restricted by the adjacent left vehicle seat 1L as shown in FIG. Also, the locking mechanism 90R is prevented from being displaced to the left. Note that the left vehicle seat 1L that has received a leftward force from the right vehicle seat 1R tends to move to the left, but the position of the striker 98L for the left vehicle seat 1L that is symmetrically formed. The movement is regulated by the displacement prevention member 100, and displacement of the lock mechanism 90 of the left vehicle seat 1L is prevented.

In the striker 98 of the present embodiment as described above, the following effects can be achieved.
Even when the locking mechanism 90R moves along the connecting portion 220 and moves toward the upper end portion 211 of the rod portion 210R, the locking mechanism 90R contacts the position shift prevention member 100 before reaching the upper end portion 211 of the rod portion 210R. The positional deviation of the lock mechanism 90R with respect to 220 can be prevented.

  Since the movement of one of the left and right vehicle seats 1R, 1L to the inner side in the left-right direction is suppressed by the other vehicle seat, the displacement prevention member 100 is wasted on the rod portion 210 side on the inner side in the left-right direction. It is not necessary to provide it, and the cost can be reduced.

  Since the misalignment prevention member 100 is configured separately from the loop portion 200, it can be formed corresponding to the size, shape, etc. of the lock mechanism 90, and the displacement of the lock mechanism 90 can be better suppressed to prevent misalignment. can do.

  By disposing the positional deviation preventing member 100 inside the rod portion 210R, the positional deviation preventing member 100 is supported by the rod portion 210R when the lock mechanism 90R abuts against the positional deviation preventing member 100, so that it is more reliable. Misalignment can be prevented.

  By forming the notch portion 111 into which the connecting portion 220 enters the upper edge portion of the misalignment prevention member 100, the contact surface between the misalignment prevention member 100 and the lock mechanism 90 can be increased. The movement of the rod part 210 to the upper end part 211 can be reliably suppressed, and displacement can be prevented more reliably.

  By forming the positional deviation preventing member 100 in a flat plate shape, the locking mechanism 90 can be received on the wide surface of the positional deviation preventing member 100, so that positional deviation can be prevented more reliably.

Although the embodiments of the present invention have been described above, the present invention can be implemented with appropriate modifications as shown in other embodiments below.
In the above-described embodiment, the direction (extending direction) of the connecting portion 220 is directed in the left-right direction of the vehicle 2, but the present invention is not limited to this, and the direction of the connecting portion depends on the orientation of the seat with respect to the vehicle body. You may change suitably.

  In the embodiment, the notch 111 is formed at the upper edge of the misalignment prevention member 100. However, the present invention is not limited to this, and for example, the notch may be formed on the side edge of the misalignment prevention member. .

  In the embodiment, the misalignment prevention member 100 is provided only on the rod portion 210 on the outer side in the left-right direction among the two rod portions 210. However, the present invention is not limited to this, and one for each of the two rod portions. You may provide a position shift prevention member one by one. Moreover, the position shift prevention member may not be a flat plate-like member as in the above-described embodiment, and may be constituted by, for example, a plurality of rod-like members.
