Description

[0001] Vehicle seat with a coupling device for a screen and motor vehicle

[0002] DESCRIPTION:

[0003] The invention relates to a vehicle seat for a motor vehicle, wherein a screen can be arranged on the vehicle seat, which screen is designed to output content to a rear passenger of the motor vehicle.

[0004] In a motor vehicle, it may be desirable to provide screen content to vehicle occupants located in the rear of the vehicle. In this context, there are mounts that can be attached, for example, to the headrest bars of a front vehicle seat headrest. A screen can be secured to the mount. Once the screen is secured to the mount, the occupant located in the rear of the vehicle can view the content displayed on the screen.

[0005] With such rear seat entertainment systems or rear seat entertainment systems, it is particularly important to ensure that certain acceleration values ​​are not exceeded in the event of a collision between the rear passenger and the screen or the holder.

[0006] DE 10 2020 112 131 B3 describes an assembly for a vehicle comprising a cross member intended to be connected to two pillars opposite one another in the direction of the vehicle's transverse axis. A mount for a display is arranged on the cross member, with straps of the mount having predetermined bending points. An acceleration acting on the display, for example, in the event of an accident due to the impact of a vehicle occupant's head, results in bending stress, causing it to buckle at the predetermined bending point.

[0007] The object of the present invention is to provide a vehicle seat of the type mentioned at the outset which is improved with regard to the safety of the rear passenger, and to provide a motor vehicle with at least one such vehicle seat.

[0008] This object is achieved by a vehicle seat having the features of patent claim 1 and by a motor vehicle having the features of patent claim 10. Advantageous embodiments with expedient further developments of the invention are specified in the dependent patent claims and in the following description.

[0009] A screen designed to output content to a rear passenger of the motor vehicle can be arranged on the vehicle seat according to the invention for a motor vehicle. The vehicle seat comprises a coupling device which has a fastening section and at least one support arm. The coupling device is fixed in the fastening section to a structural component of the vehicle seat. A holding device can be fixed to a holding section of the at least one support arm, wherein the screen can be arranged or arranged on the vehicle seat by means of the holding device. The at least one support arm has a connecting region connecting the fastening section to the holding section. In this case, the connecting region has a greater elastic deformability than the structural component of the vehicle seat.

[0010] In other words, the connecting region is more flexible when subjected to a load, for example in the form of an impact, on the coupling device than is the case for the structural component of the vehicle seat. This is advantageous, for example, to reduce acceleration values ​​that arise when a rear passenger exerts a force, for example with their head, on the holding device, wherein the holding device is fixed to the holding section of the at least one support arm. This is because, when subjected to such a load on the holding device, the connecting region of the at least one support arm can deform elastically much more easily and to a greater extent than is the case for the rigid structural component of the vehicle seat. This is due to the fact that the connecting region has greater elastic deformability than the structural component, and can therefore be elastically deformed more easily than the structural component of the vehicle seat.

[0011] Reducing the acceleration values ​​during such an impact of the rear passenger's head leads to increased safety for the rear passenger. Consequently, the vehicle seat is improved in terms of rear passenger safety.

[0012] To determine acceleration values ​​such as those that can occur when the head of a rear passenger impacts the holding device when the holding device for the screen is attached to the holding section of at least one support arm, tests can be conducted in which defined specifications must be observed. For example, a hemispherical pendulum body with a specific mass, suspended above the vehicle seat, can be impacted or caused to impact from a defined height onto different points on the holding device or onto different points on a trim component arranged on the holding device. The respective acceleration value during the impact can be recorded at the respective point at which the pendulum body impacts the component.

[0013] By providing the coupling device, it can be ensured, in particular, that when the pendulum body impacts different points on the trim component of the vehicle seat arranged on the holding device, the acceleration values ​​remain below specified limits. Due to the flexibility or the comparatively easy elastic deformability of the connecting area of ​​the at least one support arm, an advantageous reduction in the acceleration values ​​can be achieved.

[0014] In particular, the acceleration values ​​are significantly lower than would be the case if the pendulum body were to impact the comparatively stiff or rigid structural component of the vehicle seat. The design of the coupling device therefore significantly reduces the acceleration values ​​that occur when the pendulum body impacts predetermined areas of the vehicle seat. This is due to the fact that the kinetic energy present during the impact of the pendulum body is very effectively dissipated due to the yielding of the coupling device, with the yielding of the coupling device being caused by the elastic deformation of the connecting area.

[0015] By allowing the pendulum body to impact specific points on the vehicle seat, impact forces can be simulated, such as those that might occur when a rear passenger's head strikes those points. And by reducing the acceleration values ​​occurring during such an impact, improved protection for the rear passenger is provided. Therefore, the coupling device contributes to the safety of the motor vehicle that features the vehicle seat with the coupling device.

[0016] The provision of the coupling device is based on the recognition that the structural component of the vehicle seat, due to the strength requirements placed on it, is less able to dissipate, through elastic deformation, the kinetic energy which the pendulum body or the head of the rear passenger has when impacting certain points on the vehicle seat. In particular, occupant protection with regard to a head impact of the rear passenger can be significantly improved by providing the coupling device on the vehicle seat, which is designed to arrange the screen on the vehicle seat. Furthermore, the coupling device can be advantageously used to increase the robustness and centering of components of the vehicle seat that are different from the structural component of the vehicle seat. This applies, for example, to components such as vehicle seat upholstery or a foam body or the like.The coupling device can also be used advantageously to increase the strength of components of the vehicle seat, such as the foam body or the upholstery.

[0017] The improved safety for the rear passenger is ensured both when the screen is mounted on the vehicle seat and when the holding device, which can be attached to the holding section of at least one support arm, is not equipped with the screen. This is advantageous.

[0018] Furthermore, the provision of the coupling device advantageously provides improved occupant protection in the event that the rear passenger's head impacts areas of the vehicle seat other than the screen or the screen support device, for example, when the support device is secured to the support section of the at least one support arm. For example, the provision of the coupling device also improves occupant protection in the event that the rear passenger's head impacts a headrest part of the vehicle seat.

[0019] Preferably, the coupling device comprises at least one front-side support arm, the holding section of which extends from the connecting region to a front side of the vehicle seat, wherein the coupling device comprises at least one rear-side support arm, the holding section of which extends from the connecting region to a rear side of the vehicle seat. The holding sections of the front-side support arm and the rear-side support arm provide a readily usable storage device for the holding device. Furthermore, the holding sections of the support arms, which extend in opposite directions, are easily accessible for mounting the holding device to the support arms. This is advantageous.

[0020] Preferably, the holding section of the at least one front support arm forms an obtuse angle with the holding section of the at least one rear support arm. This ensures that, when the holding device is arranged on the holding sections of the support arms, the holding device moves virtually automatically into an assembly position in which the holding device can be secured to the support arms. This simplifies the assembly of the holding device.

[0021] The coupling device preferably comprises two front support arms and two rear support arms, wherein the two front support arms are spaced apart from each other in the transverse direction of the vehicle seat, and wherein the two rear support arms are spaced apart from each other in the transverse direction of the vehicle seat. By providing a total of four support arms with their respective holding sections, the holding device can be very well and very evenly supported by the support arms. Furthermore, an advantageous distribution of forces during elastic deformation of the connecting areas of the support arms is achieved.

[0022] The fastening section preferably comprises a support area that is fixed to a head region of the structural component. This contributes to a secure attachment of the coupling device to the structural component. Additionally or alternatively, the fastening section can comprise a fixing area that is fixed to a front side of the structural component. This is particularly advantageous for ensuring robust fixation of the coupling device in the fastening section on the structural component, for example, when a force is applied to the coupling device by the head of the rear passenger, i.e., from the rear of the vehicle seat.

[0023] Preferably, the support area is secured to the head region of the structural component by means of at least one screw element extending in the vertical direction of the vehicle seat. This is advantageous for a highly resilient attachment of the fastening section to the structural component.

[0024] The same applies if, according to a further advantageous embodiment, the fixing region of the fastening section is fixed to the front side of the structural component by means of at least one screw element extending in the longitudinal direction of the vehicle seat.

[0025] Preferably, the connecting region of the at least one support arm extends from the support region in the vertical direction of the vehicle seat to a headrest part of the vehicle seat. This ensures the desired flexibility or high elastic deformability of the connecting region in the event of the rear passenger's head impacting the screen.

[0026] Preferably, the holding device is secured to the holding section of the at least one support arm. The holding device has a receptacle, into which a connection unit of the screen can be inserted. This allows content to be output to the rear passengers of the motor vehicle when the screen is arranged on the vehicle seat. This is because the connection unit can supply the screen with electrical energy and / or data, which can be used to output the content via the screen.

[0027] Preferably, a base region of the receptacle borders on the upper side of a backrest cushion of the vehicle seat. Additionally or alternatively, it is preferably provided that an apex region of the receptacle borders on a headrest part of the vehicle seat. By arranging the receptacle in this way between the upper side of the backrest cushion of the vehicle seat and the headrest part of the vehicle seat, an arrangement of the screen on the holding device that is particularly usable for the rear seat occupant can be realized. This is advantageous for comfortable viewing of the content displayable via the screen by the rear seat occupant. It has been shown to be further advantageous if the at least one support arm of the coupling device is formed integrally with the fastening section of the coupling device or if the support arms of the coupling device are formed integrally with the fastening section of the coupling device.This makes the coupling device very easy and inexpensive to set up.

[0028] A steel material, for example, a steel material with the designation or material code S355MC, can be used as the material for the support arms and the fastening section of the coupling device. Using such a steel material allows the coupling device to be provided with thin walls and thus save weight. Furthermore, such a steel material is characterized by high strength and, in particular, high tensile strength. This is advantageous with regard to the good elastic deformability of the connecting area of ​​the at least one support arm.

[0029] The motor vehicle according to the invention has at least one vehicle seat according to the invention. A front side of the vehicle seat faces a front of the vehicle seat, and a rear side of the vehicle seat faces a rear of the motor vehicle. As a result, vehicle occupants in the rear of the motor vehicle can make good use of the screen if the screen is arranged on the vehicle seat using the coupling device. This is advantageous.

[0030] The advantages and preferred embodiments described for the vehicle seat according to the invention apply analogously to the motor vehicle according to the invention and vice versa.

[0031] The invention therefore also includes further developments of the motor vehicle according to the invention that have features already described in connection with the further developments of the vehicle seat according to the invention. For this reason, the corresponding further developments of the motor vehicle according to the invention are not described again here.

[0032] The motor vehicle according to the invention is preferably designed as a motor vehicle, in particular as a passenger car or truck, or as a passenger bus.

[0033] The invention also encompasses combinations of the features of the described embodiments. The invention therefore also encompasses implementations that each comprise a combination of the features of several of the described embodiments, unless the embodiments are described as mutually exclusive.

[0041] Fig. 8 shows a highly schematic view of the motor vehicle with the vehicle seat according to Fig. 7.

[0042] The exemplary embodiments explained below are preferred embodiments of the invention. In the exemplary embodiments, the described components of the embodiments each represent individual features of the invention that can be considered independently of one another, each of which also develops the invention independently of one another. Therefore, the disclosure is intended to encompass combinations of the features of the embodiments other than those shown. Furthermore, the described embodiments can also be supplemented by further features of the invention already described.

[0043] In the figures, the same reference symbols designate elements with the same function.

[0044] Fig. 1 shows a perspective view of a preferred variant of a coupling device 10. The coupling device 10 can be used for arranging a screen 12 (see Fig. 7) on a vehicle seat 14 of a motor vehicle 16 (see Fig. 8). In this regard, it can be seen from Fig. 8 that when the screen 12 is arranged on the vehicle seat 14, a rear passenger (not shown) of the motor vehicle 16 having the vehicle seat 14 can view content displayed on the screen 12. The screen 12 is thus part of a rear seat entertainment system of the motor vehicle 16.

[0045] As can be seen from Fig. 7, the screen 12 is located on a rear side 18 of the vehicle seat 14, wherein the rear side 18 of the vehicle seat 14 faces a rear end 20 of the motor vehicle 16 (see Fig. 8). Accordingly, a front side 22 of the vehicle seat 14 opposite the rear side 18 faces a front end 24 (see Fig. 8) of the motor vehicle 16.

[0046] For example, if the motor vehicle 16 impacts an obstacle (not shown) with its front end 24, this may cause the upper body of the rear passenger to move toward the screen 12. Particularly if the head of the rear passenger (not shown) impacts the screen 12, it is important to provide good passenger protection. This can be achieved by using the coupling device 10 shown in Fig. 1.

[0047] This is because the coupling device 10 is designed in the manner of a deformation element which is capable of reducing acceleration values ​​which may occur when the head or an object strikes the rear side 18 of the vehicle seat 14, in particular in the area of ​​the screen 12 and / or when the head or the object strikes the screen 12 itself.

[0048] It may occur that the vehicle seat 14 is equipped with the screen 12, as shown in Fig. 7. In this case, it is important to provide good protection against a head impact of the rear passenger on the screen 12. However, even if the screen 12 is not arranged on the vehicle seat 14, it is important to avoid undesirably high acceleration values ​​occurring when the rear passenger's head impacts, for example, on a trim component 26 of the rear seat entertainment system shown in Fig. 7. The trim component 26 or trim part, made of plastic, for example, can be arranged on a holding device 28 (see Fig. 2 or Fig. 5) of the rear seat entertainment system, wherein the holding device 28 is shown in Fig. 2 and Fig. 5 in a state fixed to the coupling device 10. The covering component 26 serves to conceal or cover the holding device 28 towards the surroundings of the vehicle seat 14.According to Fig. 2, the holding device 28 comprises a receptacle 30 into which a connection unit 32 of the screen 12 (see Fig. 6) can be inserted.

[0049] In Fig. 2, the receptacle 30 is shown in a perspective view essentially from the rear side 18 of the vehicle seat 14. In contrast, the receptacle 30 in Fig. 5 is shown in a perspective view essentially from the front side 22 of the vehicle seat 14.

[0050] Fig. 6 shows how the connection unit 32 of the screen 12 can be inserted into the receptacle 30 to ensure that, when the screen 12 is arranged on the vehicle seat 14 (see Fig. 7), content can be output to the rear passengers of the motor vehicle 16 via the screen 12. The trim element or trim component 26, which surrounds the connection unit 32 of the screen 12, is not shown in Fig. 6 for reasons of clarity.

[0051] The vehicle seat 14 comprises a structural component 34, which is shown in Fig. 3 in a view from the front side 22 of the vehicle seat 14. Accordingly, the front side 22 of the structural component 34 can be seen in Fig. 3. For example, according to Fig. 3, the structural component 34 can be provided by a head plate of an internal structure of the vehicle seat 14. However, the statements made below apply analogously if the coupling device 10 is attached to a structural component, for example in the form of a backrest frame of the internal structure of the vehicle seat 14. The coupling device 10 comprises a fastening section 36 in which the coupling device 10 is attached to the structural component 34 of the vehicle seat 14. Furthermore, the coupling device 10 comprises at least one support arm 38, 40, 42, 44.

[0052] According to Fig. 1, the coupling device 10 can, for example, comprise two front support arms 38, 40 and two rear support arms 42, 44. The front support arms 38, 40 are spaced apart from one another in the transverse direction y of the vehicle seat 14 (see Fig. 7). Analogously, the two rear support arms 42, 44 are spaced apart from one another in the transverse direction y of the vehicle seat 14. The transverse direction y of the vehicle seat 14 and the vertical direction z of the vehicle seat 14 are illustrated in Fig. 7 and Fig. 8 by respective coordinate systems. Accordingly, the vertical direction z of the vehicle seat 14 can be aligned parallel to the vehicle's vertical axis, and the transverse direction y of the vehicle seat 14 can be aligned parallel to the vehicle's transverse axis.

[0053] Each of the support arms 38, 40, 42, 44 shown in Fig. 1 has a respective holding section 46, 48. The holding sections 46, 48 of the support arms 38, 40, 42, 44 serve as supports for the holding device 28. In this regard, Fig. 2 shows that the holding device 28 can be screwed to the coupling device 10 in the region of the holding sections 46, 48. For this purpose, respective screw nuts 50 can be arranged on an underside of the respective holding sections 46, 48. However, other types of securing the holding device 28 to the coupling device 10 are also possible.

[0054] Each of the support arms 38, 40, 42, 44 has a connecting region 52 which connects the fastening section 36 to the respective holding section 46, 48. The connecting region 52 of the respective support arm 38, 40, 42, 44 has a greater elastic deformability or greater compliance than the structural component 34 (see Fig. 3) of the vehicle seat 14. Accordingly, if the head of the rear passenger impacts the trim component 26 (see Fig. 7) or the screen 12, the coupling device 10 provides a deformation element which has the resilient connecting regions 52.

[0055] The same applies if, for example, in the context of a test to determine the acceleration values, a pendulum body of a pendulum impacts the cladding component 26 (see Fig. 7) or the screen 12. Even when using such a test arrangement comprising the pendulum, the connecting regions 52, which can be elastically deformed more easily or simply than the structural component 34, ensure that lower acceleration values ​​are recorded or measured than would be the case without the provision of the coupling device 10.

[0056] Due to the flexible properties of the connecting regions 52, particularly in comparison to the structural component 34, the holding device 28 can move relative to the comparatively stiff and high-strength structural component 34 and thus dissipate kinetic energy which is present, for example, when the head impacts the screen 12 or the covering component 26.

[0057] The impact of the head on the screen 12 or on the trim component 26 (see Fig. 7) can be simulated, for example, by allowing the pendulum body (not shown) in the form of a metallic hemisphere with a specific mass to impact predetermined points on the trim component 26, preferably made of plastic, or on the screen 12. In this test setup or test arrangement, the pendulum body is part of a pendulum, wherein the pendulum body is suspended, for example, by means of a holding cable or the like, from a suspension point above the vehicle seat 14. By using the pendulum with the pendulum body, the acceleration values ​​upon impact of the pendulum body on predetermined points on the vehicle seat 14 can be measured or recorded in a well-defined manner.

[0058] It has been found that the coupling device 10 is capable of ensuring that, when the pendulum body impacts the trim component 26, acceleration values ​​of less than 64 g are always recorded at different locations on the trim component 26. This is advantageous for providing improved protection for the rear passenger when using the rear seat entertainment system.

[0059] According to Fig. 1, the holding sections 46 of the front support arms 38, 40 extend from the respective connecting area 52 to the front side 22 of the vehicle seat 14 (see Fig. 8). Furthermore, the holding sections 48 of the rear support arms 42, 44 extend from the respective connecting area 52 to the rear side 18 (see Fig. 8) of the vehicle seat 14.

[0060] In particular, it is clearly evident from Fig. 4 that the holding sections 46 of the front support arms 38, 40 preferably form an obtuse angle with the holding sections 48 of the rear support arms 42, 44. Furthermore, it is evident from both Fig. 1 and Fig. 4 that the connecting regions 52 of the support arms 38, 40, 42, 44 extend substantially in the vertical direction z of the vehicle seat 14, specifically toward a headrest part 54 of the vehicle seat 14 (see Fig. 7).

[0061] In Fig. 7, the support arms 38, 40, 42, 44 of the coupling device 10 are not visible, since the coupling device 10 is concealed by the upholstery of the vehicle seat 14 and a cover enclosing the upholstery, for example in the form of a cover material of the vehicle seat 14. However, it is particularly evident from a view of Fig. 6 with Fig. 7 that the support arms 38, 40, 42, 44 of the coupling device 10 are arranged below the headrest part 54 in the vertical direction z of the vehicle seat 14.

[0062] A steel material can be used in particular as the material for the coupling device 10, wherein, according to Fig. 1, the support arms 38, 40, 42, 44 can be formed integrally with the fastening section 36. To secure the coupling device 10 to the structural component 34 of the vehicle seat 14 by means of the fastening section 36, according to Fig. 3 and Fig. 4, a support region 56 of the fastening section 36 can be fixed from above to a head region 58 of the structural component 34. For this assembly of the fastening section 36 to the structural component 34, which is here designed as a head plate, screw elements 60 can be used in particular, which extend in the vertical direction z of the vehicle seat 14 and can be clearly seen in Fig. 1.For example, the two screw elements 60 extending in the vertical direction z of the vehicle seat 14 can be designed as press-in screws, which can be pre-assembled in the support area 56 on the coupling device 10.

[0063] Furthermore, according to Fig. 1, the fastening section 36 of the coupling device 10 preferably comprises a fixing region 62, which is fixed to the front side 22 of the structural component 34 (see Fig. 3). For example, the presently plate-shaped fixing region 62 can be fixed to the structural component 34 by means of two further screw elements 64, which extend in a longitudinal direction x of the vehicle seat 14 (see Fig. 8). Heads of the further screw elements 64 can be seen in the view of the front side 22 of the structural component 34 in Fig. 3. In contrast, the respective shafts of the further screw elements 64 can be seen in Fig. 1 and Fig. 2.

[0064] From Fig. 1 and Fig. 4 it is further apparent that the coupling device 10 can have a hook element 66 in the fixing region 62, which is designed to engage in a recess formed in the structural component 34 approximately in the form of the head plate shown in Fig. 3. Additionally or alternatively, the support region 56 can comprise a further hook element 68, which can engage in a through-opening formed in the head region 58 of the structural component 34. By hooking such a hook element 66, 68 during assembly of the coupling device 10 to the structural component 34, a pre-fixing can be achieved very effectively before the screw elements 60, 64 are tightened.

[0065] By providing the connecting regions 52, the holding device 28 is spaced apart from the fastening section 36 in the vertical direction z of the vehicle seat 14 (see Fig. 2 and Fig. 5). And due to the elastic deformability or resilience of the connecting regions 52, the holding device 28 can deflect at least slightly toward the front side 22 of the vehicle seat 14 if the rear passenger's head impacts the screen 12 or the trim component 26 from the rear side 18 of the vehicle seat 14.

[0066] After the holding device 28 has been secured to the coupling device 10, the vehicle seat 14 is provided with foam bodies and similar cushioning materials, as well as with a covering material, during the manufacture of the vehicle seat 14. This results in the coupling device 10 and the holding device 28 being concealed from view by an observer looking at the vehicle seat 14 from the outside.

[0067] Due to the accessibility of the mount 30, which is located inside the vehicle seat 14, from the rear side 18 of the vehicle seat 14, the screen 12 can be very easily installed or removed as needed. For this purpose, the connection unit 32 (see Fig. 6) of the screen 12 only needs to be inserted into or removed from the mount 30.

[0068] According to Fig. 6, the rear seat entertainment system may include a locking device 70 that can be actuated to unlock the screen 12 or monitor. The screen 12 can then be easily pulled out of the receptacle 30.

[0069] From Fig. 2 in conjunction with Fig. 7, it is clearly evident that a base region 72 of the receptacle 30 can adjoin an upper side of a backrest cushion 74 of the vehicle seat 14. Furthermore, an apex region 76 of the receptacle 30 can adjoin the headrest part 54 of the vehicle seat 14. Accordingly, the receptacle 30 can be arranged in the vehicle seat 14 between the upper side of the backrest cushion 74 and the headrest part 54 of the vehicle seat 14.

[0070] Fig. 7 also shows that a plate-like backrest cover 78, made of plastic, for example, can be arranged on the rear side 18 of the vehicle seat 14. This backrest cover 78 partially conceals the backrest cushion 74 of the backrest of the vehicle seat 14 toward the rear side 18 of the vehicle seat 14. However, the statements made here also apply if the vehicle seat 14 does not have such a backrest cover 78.
