Description

The invention relates to a vehicle seat arrangement comprising a vehicle seat for transporting a person in a motor vehicle, the vehicle seat having a footrest in its end region on the foot side.

In the future, passengers of autonomously driven motor vehicles will be given the opportunity to complete long-distance journeys in particular while sleeping and lying down.

However, even in the case of autonomously guided motor vehicles, which can also be networked with one another, for example due to the presence of further motor vehicle vehicles that are taking part in traffic, it cannot be ruled out that the passenger transport is always accident-free. In order to protect an occupant in the event of an accident, it is therefore necessary to establish restraint devices which ensure protection of the occupants even in the lying position.

In addition to the protection of the occupants, there is a main focus in the case of restraint devices and also in general on the comfort made possible for the occupants, which is of essential importance in particular on long-distance journeys.

To increase comfort, motor vehicle seats with footrests, which are not very widespread, are known, inter alia, from the field of motor vehicle seats, which also has safety relevance in conventional, passenger-guided motor vehicles.

In a related area, the US 6 929 320 B2 In addition, an aircraft seat is described which has a legrest with a footrest which is arranged to be longitudinally displaceable on the legrest, so that the length of the legrest is variable. Leg supports and a backrest are also connected to a seat structure via swivel connections, with a synchronized pivoting movement of the backrest, seat structure and leg support being achieved when moving from a seat to a semi-lying position by means of a synchronization mechanism.

The WO 01/25 053 A1 further discloses a vehicle seat which has only a seat position and which, in addition to a backrest and a seat structure, also has a legrest with a footrest arranged on the legrest. The legrest is pivotally mounted on the seat structure by means of a motor, the footrest is arranged on the legrest so as to be longitudinally displaceable by means of a motor, wherein pivoting and longitudinal displacement can be initiated by the seat occupant via a control unit.

Through the DE 102 09 234 B4 In turn, a motor vehicle seat with only one sitting position is known, with a lower leg support that is continuously adjustable via a motor between a stowed position and a use position, the lower leg support being designed to be variable in length via a three-part telescopic arm operated by a spindle drive. The lower leg support can also be changed in its inclination angle with respect to the seat surface of the motor vehicle seat by means of an inclination adjuster. At the end of the lower leg support facing the motor vehicle floor there is also a footrest which can be pivoted about an axis of rotation transversely to the lower leg support.

The disclosed seats, however, have in common that - as already mentioned - the footrests arranged on them only serve to increase comfort and, in particular, to rest the feet, but not to increase the safety of a vehicle occupant.

Against this background, the invention is based on the object of designing the vehicle seat arrangement of the type mentioned at the outset in such a way that there is increased safety for an autonomously driven motor vehicle.

This object is achieved with a vehicle seat arrangement according to the features of claim 1. The subclaims relate to particularly expedient developments of the invention.

According to the invention, a vehicle seat arrangement is therefore provided which has a vehicle seat for transporting a person in a motor vehicle, the vehicle seat having a footrest in its end region on the foot side. It can be provided here that the vehicle seat has a lower leg support in addition to the footrest, to which the footrest connects. In addition, a thigh and / or pelvis support, a back support and a headrest are also conceivable.

According to the invention, a restraining device of the vehicle seat arrangement with at least one adjustment area, which is adjustable to a body size of the person in a lying position on the vehicle seat, is furthermore arranged in the foot-side end area of the vehicle seat having a lying state. An adjustment range would be an area of the restraint device that could be adjusted to the body size of the person, such being a regular range Adjustment range can be provided so that an individual adjustment per foot would not be possible. However, one adjustment area per foot of the person and thus two adjustment areas of the restraint device can also be provided, so that the restraint device can also be adjusted in an adaptable manner depending on an individual foot positioning of the person on the vehicle seat.

The adjustment of the restraint device, which is intended to adapt to the body size of the person sitting on the vehicle seat, serves in particular to ensure that the pelvis of people with different body sizes is always in the substantially same position on the vehicle seat that is in the lying state. As a result, the retaining device can advantageously be, for. B. with a supplementary securing device such as a flexible surface element, in particular made of mesh, fabric, knitted fabric, knitted fabric or film, which in a position of use covers at least part of the body surface of the person and is particularly releasably connected to the vehicle seat and / or a vehicle structure . This leads to an extremely increased securing of the person in the vehicle seat. Such a flexible surface element can be, for example, a safety blanket.

There is also the possibility that the vehicle seat only has a lying state and therefore cannot be understood in the true sense of a seat. The footrest and other vehicle seat, which can also consist, for example, of the aforementioned lower leg support, thigh and / or pelvic support, as well as the backrest and headrest, can be made in one piece. On the other hand, it is also conceivable that the footrest and a further vehicle seat are made in several parts with, for example, separately executed and interconnected lower leg supports, thigh and / or pelvic supports as well as a backrest and headrest.

In contrast to the exclusive lying state, in which the vehicle seat is designed as a bed, another embodiment of the vehicle seat consists in that it has both a sitting state and a lying state, between which the vehicle seat can be transferred.

In accordance with the invention, the restraint device of the vehicle seat arrangement is in an accident situation in contact with the person lying on the vehicle seat - in this case in particular with at least one foot, preferably with both feet of the person - so that at least parts of the person during the accident situation Forces acting in the direction of the restraint device are transmitted to and / or absorbed by the person and the restraint device on the restraint device. As a result, the person is restrained accordingly on the vehicle seat, and the person therefore does not slide off the vehicle seat. In practice, it can be provided here that the restraint device is not only in contact with the person and in particular with at least one foot, preferably with both feet, during the accident situation.

For the proper functioning of the restraint device, the vehicle seat should of course be oriented in the direction of travel so that the restraint device can absorb an accident situation and in particular a frontal impact of the motor vehicle, in which the resulting forces act in the direction of the restraint device.

In order to avoid overloading the person and in particular the legs and / or feet in the event of an accident, the restraint device should have a force limitation which causes the restraint device to be adjusted in the direction of the force acting on it, so that the forces acting on the person and / or over the person-derived forces do not exceed a critical height.

Furthermore, an embodiment of the vehicle seat arrangement is profitable if the restraint device has at least one — in particular flat — support means and / or at least one support housing open to the person. The support means or the support housing are the components which are intended to establish contact with the person and via which the forces acting during the accident situation are introduced into the restraint device. The adaptation to the body size of the person on the vehicle seat can be made accordingly by adjusting the support means and / or the support housing. It is conceivable that the support means is designed in a simple manner as a footrest in the form of a plate, which could also have padding. The support housing could also be in the form of a box or box, the opening of which is directed towards the person. The support housing has the advantage of being able to at least partially enclose the person's feet, which minimizes the risk of the person sliding, in particular the person's feet from the restraint device.

In an extremely advantageous development of the invention, the footrest is part of the restraint device, the restraint device being arranged, in particular by being translationally movable the footrest on the vehicle seat is adjustable. The footrest movably arranged on the vehicle seat, for example the lower leg support of the vehicle seat and thus the restraint device itself, can be connected to the vehicle seat, for. B. connected via one or more guide rails or a telescopic arrangement or supported on the vehicle seat. The adjustment of the restraint device can accordingly take place directly via an actuator that is indirectly operatively connected to the telescopic arrangement, the footrest or another component of the restraint device, such as the support means or the support housing, or via gear elements.

As to ensure the comfort of the person sitting on the vehicle seat, the vehicle seat and the footrest and generally also components of the restraint device, such as the support means and / or the support housing, are provided with upholstery, should change due to the adjustment of the footrest and thus Spacing of the footrest and vehicle seat, or a changing space between the footrest and vehicle seat, a cushion cover covering the space can be provided, by means of which the changing spacing can be compensated. For this purpose, a storage space can be provided in the end region of the vehicle seat, for example on the side of the vehicle seat facing away from the person, into which the upholstery can slide, for example according to the principle of a roller shutter. For this purpose, a deflection roller could be provided, over which the upholstery or the upholstery is guided. It is also conceivable that the upholstery and / or the upholstery is slidably guided in guide rails arranged on the side of the vehicle seat. Another possibility for ensuring comfort would also be that at least the space between the footrest and the vehicle seat is spanned by means of a cover, the cover being in a tensioned state with the maximum spacing between the footrest and the vehicle seat. If the spacing is reduced, the cover should form a coverless cover which is inserted into the intermediate space or the storage space, for example by forming at least one loop. As a result, the person is advantageously or only minimally impaired in their comfort on the vehicle seat.

One embodiment of the invention is also to be regarded as promising if the restraint device is adjustable by means of - in particular translationally - movable arrangement of the support housing and / or the support means - in particular on the stationary footrest. Here, the support means or the support housing z. B. be guided on both sides of the footrest guide rails, which is a structurally advantageous way to realize a translational movement of the support housing and / or the support means.

Fixed here means a fixed arrangement with respect to the vehicle seat. B. an adjustment of the restraint is still possible.

It is also advantageous if the retaining device, which is arranged in a fixed manner, in particular on the footrest, can be adjusted on the support means or in the support housing by arranging at least one airbag or also an impact cushion. This could advantageously provide a restraint device that would be loaded without the arrangement of moving parts and thus a wear-prone adjustment of the restraint device. In this case, the airbag would preferably be arranged in the support housing, as a result of which the direction of expansion is advantageously limited and directed when the airbag is triggered. An adapting adjustment and the contact with the person is thus only provided in the accident situation, whereby z. B. would always be established a comfort distance between the restraint and the person in a normal situation or a pre-accident situation. In an expedient manner, the airbag - or in the case of more than one adjustment area provided, a number corresponding to the adjustment areas - should be arranged in the support house on a wall of the support house opposite the opening of the support house facing the person.

In a promising embodiment, the restraint device - in particular on the footrest - is arranged in a fixed position, the restraint device being adjustable in the support housing by means of a movable arrangement of the support means, in particular in a translatory manner. In this case, actuators such as linear drives and / or gear elements for converting the movement generated by the actuators should be arranged in and / or on, or in the region of the support housing. This advantageously leads to the fact that the restraint device is not adjusted via the vehicle seat or components of the vehicle seat such as the footrest, as a result of which no actuators and / or gear elements have to be integrated into the vehicle seat. In addition, it is simplified in addition to a purely translational movement of the support means or also the support housing to enable tilting movements of the support means, as a result of which the restraint device would also be adjustable to a tilt position of the person's feet. A tilting movement for generating an angle of inclination of the support means can be achieved, inter alia, by spacing two actuators with linear actuating movement, such as. B. linear drives, depending on the adjustment range of the restraint device or the support means and setting a different travel between the actuators. Superimposed movements, ie a translatory movement with simultaneous tilting movement, are of course also possible.

Furthermore, an advantageous further development is also characterized in that the stationary retaining device has a support means, in particular on the footrest, which is arranged to be pivotable about an axis of rotation, and at least a part of a surface of the support means facing the person has a curvature, the part of the surface pointing in the direction the person-directed pivoting of the support means is adjustable adjustable. The curvature is accordingly designed such that when the support means is pivoted in the direction of the person, the surface or the curved part of the surface of the person approaches, while when pivoting towards the person the distance to the person and in particular to the feet of the person increases. The restraint device can thus advantageously be adjusted to different body sizes of the person on the vehicle seat by simply pivoting the support means.

An embodiment of the invention in which the adjustable restraint device is arranged in the end region of the vehicle seat at the foot is connected to a vehicle structure that is not a vehicle seat. Instead of an arrangement of the restraint device on the vehicle seat and in this case preferably on the footrest of the vehicle seat, it can accordingly be provided in a further development that the restraint device is positioned in the end region on the foot side, but is connected to the vehicle structure, which can be, for example, a vehicle body of the motor vehicle. There is therefore no direct connection to the vehicle seat.

It is also considered to be favorable if the restraint device has a comfort distance from - in particular the feet - of the person in an uncritical normal situation, the comfort distance being in an emergency situation, such as a pre-accident situation or also a pre-crash situation, or an accident situation Contact is adjusted. In order not to bother the person in the vehicle seat, who is, for example, in a resting or even sleeping phase, with the constant contact of the restraint device and thus to disrupt the comfort thereof, there is the possibility during a normal situation, such as uncritical driving of the motor vehicle during the transportation of the person to establish a comfort distance between the restraint device and the person. It is conceivable here that the restraint device and, for example, the support means or the support housing remain in a rest position until an emergency situation or an accident situation occurs. It is also possible that the comfort distance is kept at a constant value, so that the restraint device is adjusted in a tracking manner. For this purpose, the restraint device would have a distance measuring means, which can be designed, for example, as a distance sensor, in particular as a capacitive distance sensor. A possible arrangement of the distance measuring means can take place on the support means or in the support housing.

A promising embodiment of the invention is also given when the adjustment - the restraint device and in particular the support means and / or the support housing - is carried out by at least one linear drive and / or at least one actuator and a transmission which converts the movement of the actuator. In addition to the linear drives, actuators such as motors are possible that generate a rotary movement. However, the rotary movement generated by a motor must be regularly converted into a translatory movement, since, except in the case of the support means having an at least partially curved surface, a translatory movement is necessary to adjust the restraint device in an adaptable manner. The changing gear can z. B. be a shear joint moved via a spindle drive. The shear joint can have two shear arms, heads of the shear arms facing away from the spindle drive in a guide arranged on the component to be moved or the assembly to be moved, such as. B. a slide rail are positioned. The transmission can also be designed as a swivel lever drive which has, for example, two swivel arms. The heads of the swivel arms can be arranged in a guide as well as a slide rail on the component to be moved or the assembly to be moved. The component or assembly can be the footrest, the support means or the restraint itself. In particular, the gear in the form of the spindle drive and the shear joint and / or the swivel lever drive should be arranged in the support housing and connected to the support means. The actuators and / or the linear drives can also be designed as a telescopic drive or connected to a telescopic drive in the sense of the transmission. Telescopic drive and telescopic drive can have several nested telescopic elements which can be moved apart and moved together for adjustment.

1 shows three vehicle seat arrangements to illustrate the inventive concept. A respective vehicle seat arrangement has a vehicle seat 1 with one in the foot end area 4th of the vehicle seat 1 arranged footrest 5 on. The vehicle seat 1 is used to transport the on the vehicle seat 1 located person 2nd . In autonomous driving applications, this transport is said to be in a lying position of the person 2nd can be done to rest or sleep the transported person, for example on long-distance journeys 2nd to enable. For this reason, the vehicle seat shows 1 a lying state in which the person 2nd can be transported in a stretched, lying position. It also shows that the respective on the vehicle seats 1 persons in a lying position 2nd have a different body size, but their pelvis are in essentially the same position on the vehicle seat 1 at the level of the indicated pelvic line B where the people are 2nd can advantageously be secured with a further safety device without having to laboriously adapt it to different body sizes. For the safety of people 2nd To increase during transport is in the end area on the foot side 4th the adjustable restraint 6 with an adjustment range 7 arranged, which to the body size of the respective, in a lying position on the vehicle seat 1 located person 2nd is customizable. The restraint device is located in an accident situation that may occur 6 in contact with the person and thereby with the feet of the respective person 2nd , so that occurring in this accident, towards the restraint 6 on the person 2nd acting forces from the restraint 6 be included. This advantageously leads to the person 6 does not slide due to the inertia and thereby possibly from the vehicle seat 1 is thrown.

The 2a and 2b is again a clarification of the adjustment of the restraint 6 remove, the restraint 6 in the training of 2a and 2 B stationary opposite the vehicle seat 1 arranged and by the translationally movable arrangement of the support means 8th in the support housing 9 is adjustable. The restraint 6 and here the proppant 8th is in contact with the person's feet 2nd , the in the 2a depicted person 2nd has a taller height than that in the 2 B depicted person 2nd so that the proppant 8th further towards the person 2nd is adjusted or has a longer travel range. Adjusting the proppant 8th is indicated by the arrow P.

The 3a to 3c disclose a possible embodiment of the restraint 6 which is the proppant 8th has, wherein the proppant 8th as shown in contact with the person 2nd and with the feet of the person 2nd located. The proppant 8th is always in contact with the person in an accident situation 2nd adjusted. However, the contact can also exist in a normal situation and always the person 2nd secure against sliding. The restraint device shown in the figures 6 is now designed so that the footrest 5 in conjunction with that on the footrest 5 arranged support means 8th the restraint 6 forms and thereby the footrest 5 opposite the vehicle seat 1 is arranged translationally movable, which is the adjustment of the restraint 6 towards and against the person 2nd enables. The footrest 5 is for this on the at the vehicle seat 1 arranged telescopic drive 3rd connected to the vehicle seat. Because to ensure the comfort of sitting on the vehicle seat 1 located person 2nd The gap 20 between the footrest 5 respectively the restraint 6 and the vehicle seat 1 with the upholstery 18th or the reference 19th should be covered or covered, it is necessary to use the upholstery 18th or the reference 19th to be designed so that covering or covering over the entire adjustment range of the restraint device 6 is possible. For this the in 3a shown upholstery 18th the padless 21 on which the changing spacing or the gap 20 between footrest 5 and vehicle seat 1 can be compensated. For this is in the end area 4th of the vehicle seat 1 on which the person 2nd opposite side of the vehicle seat 1 the storage space 22 provided in which the Upholstered 21 can initiate. For this, the upholstery 18th or the upholstery 21 over the pulley 23 guided. With one towards the person 2nd directional adjustment of the restraint 2nd the movement sequence marked with the arrows P thus results. Regarding the in the 3b and 3c shown reference 19th it can be seen from the figures that the person 2nd in the 3b is taller than the person 2nd in 3c so that the reference 19th in 3b stretched and the gap 20 covered. The reference 19th in 3rd on the other hand, has an unrelated, which is in the space 20 by forming a loop.

The restraint of the 4a and 4b shows the support dwelling 9 and has two adjustment ranges 7 which over the Mittelsteg 24th are separated from each other. The restraint 6 is due to the translationally movable arrangement of the support housing 9 on the footrest 5 adjustable. For separate adjustment of the respective adjustment ranges 7 the restraint 6 respectively the support dwelling 9 depending on the individual positioning of the person's feet 2nd is a respective adjustment range 7 via guide rails 25th , 25a on the footrest 5 arranged.

In the in the 5a and 5b shown further development of the restraint device 6 has the restraint 6 again the support housing 9 and that in the support house 9 via the two linear drives 15 Support means arranged in a translationally movable manner 8th on. The linear drives 15 are spaced from each other on the person 2nd the opening of the support housing 9 opposite wall of the support dwelling 9 arranged. This makes it like in 5a shown, possible with the same adjustment of the linear drives 15 a purely translational movement of the support means 8th in the support housing 9 to effect. In the case of unequal adjustment or unequal travel of the linear drives 15 can, as in 5b demonstrated an inclination of the proppant 8th effect, which is also superimposed with a translational movement.

6a and 6b describe the restraint 6 with again in the support house 9 Support member arranged to be translationally movable 8th . Adjusting the restraint 6 about the translationally movable arrangement of the support member 8th in the support housing 9 is done via the actuator 16 and that is the movement of the actuator 16 walking gear 17th . That in the support house 9 arranged, changing gear 17th is in the case of 6a that also about the gearbox 17th associated spindle drive 26 moving shear joint 27 . The shear joint 27 has two shear arms 28 , the spindle drive 26 averted heads 29 the shear arms 28 in the support means to be adjusted 8th arranged leadership 30th , which is designed here as a slide, are positioned. By rotating the actuator designed as a motor 16 the translational movement of the support aid results 8th what is indicated by the respective arrows P. In 6b is the transmission 17th than that in the support house 9 arranged swivel lever drive 31 which the two swivel arms 32 having. The heads 33 the swivel arms 32 are also in the leadership 30th , which is designed as a slide rail, on the support means to be adjusted 8th arranged. The movement of the driven swivel levers 32 and the resulting translational movement of the support aid 8th are again indicated with arrows P.

The 7a and 7b describe the stationary restraint device 6 , this by arranging the airbag 10th in the support housing 9 is adjustable. Here shows the 7a the airbag 10th in a normal situation and thus before the airbag is deployed 10th . In this uncritical normal situation, the restraint device points 6 the comfort distance 14 to the person 2nd on. The comfort distance 14 However, in an accident situation such as this one 7b is shown, adjusted for contact. In this embodiment, the adjustment takes place by triggering and the associated expansion of the airbag 10th until this comes into contact with the person 2nd occurs.

In the 8a and 8b has the restraint 6 that about the axis of rotation 11 pivoting support means 8th on being one of the person 2nd facing part of the surface 12th of the proppant 8th has a curvature. The curved part of the surface 12th is through towards the person 2nd directed pivoting of the support means 8th adjustable, so that the support means 8th the person 2nd approximates. In the opposite of the person 2nd directed pivoting of the support means 8th the distance of the curved part of the surface increases 12th of the proppant 8th to the person 2nd . The movements are indicated by arrows P.

9 is an embodiment of the restraint 6 with the support means arranged to be movable in translation 8th to see which is slidably guided in a rail. Here is the adjustable restraint 6 in the foot end area 4th of the vehicle seat 6 arranged and with the vehicle structure 13 connected, which is not a vehicle seat 1 is.
