[0030] This application provides a vehicle seat assembly 10, Figure 1 This is a schematic diagram showing the vehicle seat assembly 10 installed inside the passenger compartment 20. Figure 2 yes Figure 1 A schematic diagram of the structure of the vehicle seat assembly 10. Figure 3 yes Figure 2 Rear view of the vehicle seat assembly 10 shown.
[0031] Combination Figure 1 The vehicle seat assembly 10 is installed inside the vehicle compartment 20. The vehicle can be any type of vehicle, and the figure shows a truck. The vehicle seat assembly 10 can be the rear seat assembly of the vehicle, which is located at the rear of the vehicle relative to other seat assemblies.
[0032] Combination Figure 2 as well as Figure 3 The vehicle seat assembly 10 includes a seat cushion 11 and a backrest 12. The bottom of the backrest 12 is connected to the seat cushion 11, and the backrest 12 can be folded to fit against the top surface of the seat cushion 11. One backrest 12 and one seat cushion 11 constitute a seat. The vehicle seat assembly 10 may include multiple seats, which can be arranged side by side, and the seat cushions 11 of multiple seats can be arranged side by side. Figure 2 as well as Figure 3 The image shows a vehicle seating assembly 10 comprising three seats, but this is not a limitation.
[0033] The vehicle seat assembly 10 also includes a first leg 13 and a second leg 14, both of which are connected to the seat cushion 11 to support it. In this configuration, the tops of the first leg 13 and the second leg 14 are connected to the seat cushion 11, while the bottoms support the vehicle floor. It should be understood that regardless of the number of seats, only two legs are required; this satisfies the need to support the seat cushion 11 and simplifies the structure for easier storage.
[0034] Regarding the specific arrangement of the first support leg 13 and the second support leg 14, the first support leg 13 and the second support leg 14 can be spaced apart within the vehicle compartment 20 along the width direction of the vehicle, with the first support leg 13 positioned closer to the inner wall of the vehicle compartment 20 than the second support leg 14. In this case, multiple seats of the vehicle seat assembly 10 are arranged side-by-side along the width direction of the vehicle, and the first support leg 13 and the second support leg 14 can be respectively positioned on the seat cushions 11 at both ends of the width direction of the vehicle. The first support leg 13 is positioned closer to the inner wall of the vehicle compartment 20 than the second support leg 14; that is, when the vehicle seat assembly 10 is in its normally unfolded and usable state, the first support leg 13 is closer to the inner wall of a specific side of the vehicle. This specific inner wall is the inner wall that the vehicle seat assembly 10 needs to conform to when it is in its folded-up state.
[0035] Continue to combine Figure 2as well as Figure 3 The vehicle seat assembly 10 also includes a link 15, with a first end connected to a first support leg 13 and a second end connected to a second support leg 14. The link 15 is rotatable relative to the first support leg 13 and the second support leg 14. Therefore, the first end of the link 15 is rotatably connected to the first support leg 13, and the second end of the link 15 is also rotatably connected to the second support leg 14, so that the link 15 can rotate relative to the first support leg 13 and the second support leg 14.
[0036] Figure 4 This is a schematic diagram of the vehicle seat assembly 10 rotating towards the vehicle's interior wall. Figure 5 This is a rear view of the vehicle seat assembly 10 after it has been rotated and fitted into the inner wall of the passenger compartment 20. Figure 6 This is a side view of the vehicle seat assembly 10 after it has been rotated and fitted into the inner wall of the passenger compartment 20.
[0037] Combination Figures 4-6 The seat cushion 11 can rotate upward relative to the first leg 13 to fit against the inner wall of the carriage 20, so that the connecting rod 15 rotates relative to the first leg 13 and the second leg 14, so that the connecting rod 15 drives the second leg 14 to rotate toward the seat cushion 11 to fit against the bottom of the seat cushion 11.
[0038] Specifically, the first support leg 13 can be fixed to the floor of the carriage 20, while the bottom of the second support leg 14 can be either not fixed to the floor of the carriage 20 or detachably fixed to the floor of the carriage 20. In this case, the seat cushion 11 at the second support leg 14 can be lifted, causing the seat cushion 11 to rotate upwards relative to the first support leg 13 towards the inner wall of the carriage 20. At this point, the seat cushion 11 is actually rotating towards the inner wall of the carriage 20 in the width direction of the vehicle, with the top of the first support leg 13 as the pivot point. Of course, before the seat cushion 11 rotates relative to the first support leg 13, the backrest 12 can be folded to fit against the top surface of the seat cushion 11.
[0039] As the seat cushion 11 rotates relative to the first support leg 13, the connecting rod 15 also rotates upwards relative to the first support leg 13, moving closer to the inner wall of the carriage 20. During the rotation of the connecting rod 15, the second support leg 14 rotates towards the seat cushion 11, that is, it rotates the seat cushion 11 towards its bottom, causing the second support leg 14 to fit against the bottom of the seat cushion 11. After the seat cushion 11 is fitted against the inner wall of the carriage 20, the connecting rod 15, the first support leg 13, and the second support leg 14 are roughly in a vertical position, thus achieving a good folded-up state.
[0040] In summary, by configuring the link 15, which connects to the first support leg 13 and the second support leg 14, the seat cushion 11 has a device underneath that can prevent the movement of objects. Furthermore, by adjusting the strength of the link 15, the specific regulatory requirements for vehicle trunk impact tests can be met. Additionally, during the folding process of the vehicle seat assembly 10, the link 15 can drive the second support leg 14 to rotate and fold, thus facilitating the folding of the vehicle seat assembly 10 and achieving better storage performance.
[0041] Combination Figure 3 In some specific embodiments, the connecting rod 15 includes a first rod portion 151, a bent portion 152, and a second rod portion 153. The bent portion 152 connects the first rod portion 151 and the second rod portion 153. The first rod portion 151 is connected to the first support leg 13, and the second rod portion 153 is connected to the second support leg 14. The first rod portion 151 is rotatably connected to the first support leg 13, and the second rod portion 153 is rotatably connected to the second support leg 14, thereby achieving a rotatable connection between the connecting rod 15 and the first support leg 13 and the second support leg 14.
[0042] When the seat cushion 11 is horizontally positioned, i.e., when the seat assembly is in normal use rather than in a stowed state, the first rod 151 and the second rod 153 are horizontally positioned and extend horizontally. At this time, the second rod 153 is lower than the first rod 151, meaning the second rod 153 is lower than the first rod 151 in the vehicle height direction, so that when the seat cushion 11 is against the inner wall of the passenger compartment 20, the second rod 153 can avoid obstructing the seat cushion 11. Figure 4 As can be seen, this arrangement allows the second rod 153 to avoid the seat cushion 11, thereby facilitating the storage of the vehicle seat assembly 10.
[0043] Furthermore, in some specific embodiments, the second rod portion 153 is longer than the first rod portion 151, and the length of the second rod portion 153 is less than the length of the seat cushion 11 in the vehicle width direction. The specific arrangement of the lengths of the first rod portion 151 and the second rod portion 153 can be set according to actual conditions and is not specifically limited here.
[0044] Figure 7 This is a schematic diagram of the connection between the link 15 of the vehicle seat assembly 10 and the second support leg 14.
[0045] Combination Figure 7 In some specific embodiments, the first end of the connecting rod 15 is rotatably connected to the first support leg 13 via the first connecting shaft 161, and the second end of the connecting rod 15 is rotatably connected to the second support leg 14 via the second connecting shaft 162, so that the connecting rod 15 can rotate relative to the first support leg 13 and the second support leg 14.
[0046] At this time, the connecting rod 15 can rotate relative to the first connecting shaft 161, thereby achieving rotation relative to the first support leg 13. The connecting rod 15 can also rotate relative to the second connecting shaft 162, thereby achieving rotation relative to the second support leg 14.
[0047] To avoid abnormal noise when the link 15 rotates relative to the support leg, in some specific embodiments, the vehicle seat assembly 10 also includes a bushing (not shown), which is disposed between the first connecting shaft 161 or the second connecting shaft 162 and the link 15 to separate the first connecting shaft 161 or the second connecting shaft 162 from the link 15.
[0048] Correspondingly, a first bushing can be provided at the first connecting shaft 161, and a second bushing can be provided at the second connecting shaft 162. The first bushing is used to separate the connecting rod 15 from the first connecting shaft 161, and the second bushing is used to separate the connecting rod 15 from the second connecting shaft 162. Specifically, the bushing can be installed inside the shaft hole of the connecting rod 15, and the connecting shaft can then pass through the bushing installed inside the shaft hole, thereby achieving the connection between the connecting rod 15 and the connecting shaft.
[0049] Further integration Figure 4 as well as Figure 7 In some specific embodiments, the first support leg 13 and the second support leg 14 are respectively provided with a first mounting part 171 and a second mounting part 172. The first mounting part 171 protrudes relative to the first support leg 13 toward the second support leg 14. The first mounting part 171 is used to rotatably connect with the first end of the connecting rod 15, and the second mounting part 172 is used to rotatably connect with the second end of the connecting rod 15.
[0050] The first mounting portion 171 and the second mounting portion 172 are provided to facilitate the installation of the connecting rod 15 onto the first support leg 13 and the second support leg 14. Combined with the aforementioned arrangement of the first connecting shaft 161 and the second connecting shaft 162, the first connecting shaft 161 can be positioned on the first mounting portion 171, and the second connecting shaft 162 on the second mounting portion 172. By protruding the first mounting portion 171 relative to the first support leg 13 towards the second support leg 14, a good avoidance effect can be achieved between the connecting rod 15 and the seat cushion 11 during seat folding and storage.
[0051] For further specific configuration of the feet, in combination with Figure 2In some specific embodiments, the first support leg 13 includes a first sub-support leg 131 and a second sub-support leg 132 arranged along the length direction of the vehicle, the second support leg 14 includes a third sub-support leg 141 and a fourth sub-support leg 142 arranged along the length direction of the vehicle, and the connecting rod 15 includes a first connecting rod 15 and a second connecting rod 15. The first connecting rod 15 connects the first sub-support leg 131 and the third sub-support leg 141, and the second connecting rod 15 connects the second sub-support leg 132 and the fourth sub-support leg 142.
[0052] It should be understood that Figure 2 Although the first sub-support 131, the second sub-support 132, the third sub-support 141 and the fourth sub-support 142 are shown, the two connecting rods 15 are not set, and the connecting rods 15 are set in different ways.
[0053] Continue to combine Figure 2 In some specific embodiments, the vehicle seat assembly 10 also includes a main limiter 181 and a secondary limiter disposed on the seat cushion 11. The backrest 12 is connected to the seat cushion 11 through the main limiter 181 and the secondary limiter. The secondary limiter is unlocked by unlocking the main limiter 181 so that the backrest 12 can be folded and fitted to the seat cushion 11.
[0054] Specifically, the main limiter 181 and the secondary limiter are located on both sides of the seat cushion 11 in the vehicle width direction, and the secondary limiter has a similar structure to the main limiter 181. The limiters serve two purposes: first, to connect the seat cushion 11 and the backrest 12; and second, to ensure positional stability between the seat cushion 11 and the backrest 12. When the limiters are locked, the seat cushion 11 and the backrest 12 cannot rotate relative to each other; when they are unlocked, the seat cushion 11 and the backrest 12 can rotate, thus achieving folding. When the main limiter 181 is unlocked, it also causes the secondary limiter to be unlocked as well.
[0055] Continue to combine Figure 2 The main limiter 181 may be equipped with an adjusting rod 182, which can be used to unlock the main limiter 181.
[0056] Furthermore, the vehicle seat assembly 10 also includes an elastic element (not shown in the figure). One end of the elastic element is connected to the connecting rod 15, and the other end of the elastic element is connected to the first support leg 13. The position where the elastic element is connected to the first support leg 13 is lower than the position where the connecting rod 15 is connected to the first support leg 13. The elastic element can be a spring, a sheet spring, or other similar device, and no specific limitation is made here.
[0057] When the seat cushion 11 is in a horizontal position, the elastic element is compressed, so that when the seat cushion 11 rotates, the elastic element pushes the connecting rod 15 to rotate. Therefore, the elastic element provides assistance during seat folding, thus facilitating the folding of the vehicle seat assembly 10.
[0058] In another aspect, this application provides a vehicle including a vehicle seat assembly 10 as described in any of the above embodiments and a passenger compartment 20, wherein the vehicle seat assembly 10 is disposed within the passenger compartment 20.
[0059] In summary, the vehicle seat assembly 10 and vehicle provided in this application include: a seat cushion 11; a backrest 12, the bottom of which is connected to the seat cushion 11 and can be folded to fit against the top surface of the seat cushion 11; a first leg 13 and a second leg 14, both connected to the seat cushion 11 to support the seat cushion 11, the first leg 13 and the second leg 14 being spaced apart in the vehicle compartment 20 along the width direction of the vehicle, and the first leg 13 being closer to the inner wall of the compartment 20 than the second leg 14; a connecting rod 15, the first end of which is connected to the first leg 13 and the second end of which is connected to the second leg 14, the connecting rod 15 being rotatable relative to the first leg 13 and the second leg 14; wherein, the seat cushion 11 can rotate upward relative to the first leg 13 to fit against the inner wall of the compartment 20, so that the connecting rod 15 rotates relative to the first leg 13 and the second leg 14, so that the connecting rod 15 drives the second leg 14 to rotate toward the seat cushion 11 to fit against the bottom of the seat cushion 11. Therefore, by setting up link 15, on the one hand, the relevant requirements of the trunk impact test can be met, and on the other hand, the seat components can be stored, taking into account both impact resistance and good storage, thus improving the actual use performance of the vehicle.
[0060] The above description is merely an optional embodiment of this application and does not limit the patent scope of this application. Any equivalent structural transformations made based on the concept of this application and the contents of the specification and drawings of this application, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this application.
