Technical Field

[0001] This utility model relates to the field of automotive seat technology, and more specifically, to a seat adjustment device that can increase the rear seat space in a vehicle. Background Technology

[0002] Car seats are structures installed in a car for the driver or passengers to sit on. Front seats typically have rails and adjustment mechanisms to adjust their fore-aft and height. However, rear seats are usually fixed to the car's base.

[0003] In existing technology, the rear seats are directly fixed to the vehicle base, and the mounting holes on the floor panel are also correspondingly set, so the rear seats cannot be adjusted. Especially after the front seats are moved back, the distance between the rear seats and the front seats becomes very small. Utility Model Content

[0004] The purpose of this utility model is to address the problems existing in the prior art.

[0005] To solve the above problems, the present invention adopts the following technical solution.

[0006] A seat adjustment device that can increase the rear seat space in a vehicle includes: several sets of adjustment mechanisms selectable according to the number of seats; each set of adjustment mechanisms includes a first fixing plate, the first fixing plate having a first step and a second step arranged sequentially along the axial direction, the first step having a first mounting hole and a positioning hole for fixing to the vehicle base on the vertical and horizontal surfaces respectively; the second step having a first rearward displacement hole and a second rearward displacement hole for fixing to the seat on the vertical and horizontal surfaces respectively.

[0007] Compared with the prior art, the present invention has at least the following beneficial effects: The positioning holes allow for initial positioning of the first fixing plate, which is then secured to the vehicle base via the first mounting holes, facilitating its installation. Since the vehicle has a trunk, space can be provided for moving the seats backward. The seats can be fixed to the first and second rearward movement holes, allowing the entire seat to be moved backward and increasing rear passenger space. The first step allows the positioning holes and first mounting holes to be positioned on both vertical and horizontal planes, enabling fixation of the first fixing plate from two sides, resulting in a more stable fixing structure. Similarly, the second step allows the seats to be fixed to the first and second rearward movement holes on different planes, further enhancing the stability of the fixing structure.

[0008] In some embodiments, the horizontal surface on the second step extends in a direction away from the first step to form an extension portion, and the extension portion is provided with second mounting holes that are fixed to the vehicle base and third rearward displacement holes that are fixed to the seat along its extension direction.

[0009] In some embodiments, the adjustment device further includes a second fixing plate disposed on the side near the extension, the second fixing plate having at least one third mounting hole for fixing to the vehicle base, and a fourth rearward displacement hole disposed on the side of the third mounting hole away from the extension for fixing to the seat.

[0010] In some embodiments, the second fixing plate has a through groove on the side away from the extension, thereby forming two extension plates. The fourth rearward displacement hole is provided in two parts and is respectively provided on the two extension plates.

[0011] In some embodiments, the first fixing plate and the second fixing plate are disposed independently.

[0012] In some embodiments, the adjustment device further includes a lever fixed to the two fourth rearward displacement holes, and the seat is engaged with the lever.

[0013] In some embodiments, a limiting hole is provided at the bottom of the extension plate corresponding to the fourth rearward displacement hole. A bolt is inserted upward from the limiting hole and passes through the fourth rearward displacement hole. The bolt is provided with a limiting head that fits into the limiting hole. A through hole is provided on the clamping rod that fits into the screw. The clamping rod is locked on the bolt by a nut threaded onto it. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] refer to Figure 1-2 A seat adjustment device 100 that can increase the rear seat space in a vehicle includes: several sets of adjustment mechanisms 10 selectable according to the number of seats; each set of adjustment mechanism 10 includes a first fixing plate 11, the first fixing plate 11 having a first step 111 and a second step 112 arranged sequentially along the axial direction, the first step 111 having a first mounting hole 1111 and a positioning hole 1112 for fixing and cooperating with the vehicle base on its vertical and horizontal surfaces respectively; the second step 112 having a first rearward displacement hole 1121 and a second rearward displacement hole 1122 for fixing and cooperating with the seat on its vertical and horizontal surfaces respectively.

[0018] Understandably, a vertical plane is not necessarily perpendicular to the horizontal plane; it can also be an inclined vertical plane. The positioning hole 1112 serves a positioning function. For example, a hole corresponding to the positioning hole 1112 is provided on the vehicle base, and a pin, positioning rod, or similar device is inserted into the positioning hole 1112 and the corresponding hole for positioning. The first mounting hole 1111, the first rearward displacement hole 1121, and the second rearward displacement hole 1122 can be threaded holes or smooth through-hole structures, all of which can be fixed using fasteners such as screws, bolts 14, and nuts 15.

[0019] With this configuration, the positioning hole 1112 can initially position the first fixing plate 11, and then the first mounting hole 1111 can be used to fix it to the vehicle base, making it convenient to fix and install the first fixing plate 11. Since there is a trunk in the vehicle, space can be provided for the seat to be moved back, so the seat can be fixed on the first rearward moving hole 1121 and the second rearward moving hole 1122, thereby moving the entire seat back and improving the rear seat space. The setting of the first step 111 allows the positioning hole 1112 and the first mounting hole 1111 to be located on the vertical and horizontal planes, thereby fixing the first fixing plate 11 from two sides, making the fixing structure more stable. Similarly, the setting of the second step 112 can fix the seat on the first rearward moving hole 1121 and the second rearward moving hole 1122 on different planes, which can also enhance the stability of the fixing structure.

[0020] Optionally, in some embodiments, the horizontal surface on the second step 112 extends in a direction away from the first step 111 to form an extension 113. The extension 113 is provided with second mounting holes 1131 that are fixed to the vehicle base and third rearward moving holes 1132 that are fixed to the seat along its extension direction.

[0021] Understandably, the second mounting hole 1131 and the third rearward hole 1132 can be threaded holes or smooth through holes, and can be fixed by fasteners such as screws, bolts 14 and nuts 15.

[0022] With this setup, securing the first fixing plate 11 to the first fixing plate 11 using only the first mounting hole 1111 is not stable enough. Using the second mounting hole 1131 to achieve double-hole fixing improves the stability of the first fixing plate 11. Similarly, moving the third mounting hole backward enhances the stability of the seat's installation.

[0023] Optionally, in some embodiments, the adjustment device 100 further includes a second fixing plate 12 disposed on the side near the extension 113. The second fixing plate 12 has at least one third mounting hole 121 that is fixed to the vehicle base and a fourth rearward displacement hole 122 disposed on the side of the third mounting hole 121 away from the extension 113 and fixed to the seat.

[0024] Understandably, the second fixing plate 12 and the first fixing plate 11 can be installed as a single unit or installed separately. The third mounting hole 121 and the fourth rearward displacement hole 122 can be threaded holes or smooth through holes, and can be fixed by fasteners such as screws, bolts 14 and nuts 15.

[0025] With this configuration, the second fixing plate 12 can be fixed to the vehicle base through the third mounting hole 121, and the seat can be fixed through the fourth rearward moving hole 122, thereby improving the stability of the seat installation.

[0026] Optionally, in some embodiments, a through groove 123 is provided on the side of the second fixing plate 12 away from the extension 113, thereby forming two extension plates 124. Two fourth rearward displacement holes 122 are provided, and are respectively provided on the two extension plates 124. Here, the through groove 123 can save material of the second fixing plate 12 and reduce manufacturing costs.

[0027] Optionally, in some embodiments, the first fixing plate 11 and the second fixing plate 12 are independently provided. In this way, the first fixing plate 11 and the second fixing plate 12 can be manufactured separately and installed independently, and the installation positions of the first fixing plate 11 and the second fixing plate 12 can be adjusted according to the seat size.

[0028] Optionally, in some embodiments, reference is made to Figure 3-4 The adjustment device 100 also includes a locking rod 13 fixed on the two fourth rearward displacement holes 122, and the seat is locked on the locking rod 13.

[0029] Understandably, some seats can rotate, so to facilitate seat adjustment, a locking mechanism is installed on the seat. This mechanism can be secured to the locking rod 13. This locking mechanism is existing technology and will not be described in detail here.

[0030] With this configuration, by installing the locking rod 13 on the fourth rearward hole 122, it is easier to engage with the locking mechanism on the seat, making installation simpler and more convenient.

[0031] Optionally, in some embodiments, a limiting hole 125 is provided at the bottom of the extension plate 124 corresponding to the fourth rearward displacement hole 122. A bolt 14 is inserted upward from the limiting hole 125 and passes through the fourth rearward displacement hole 122. The bolt 14 is provided with a limiting head 141 that fits into the limiting hole 125. The locking rod 13 is provided with a through hole that fits into the screw. A nut 15 is threaded onto the bolt 14 to lock the locking rod 13. Here, the conventional setting is to insert the bolt 14 from top to bottom into the fourth rearward displacement hole 122, and then lock it onto the bolt 14 from the bottom of the fourth rearward displacement hole 122 with a nut 15. This method causes part of the bottom of the bolt 14 to protrude, which will abut against the vehicle base, causing inconvenience in installation. However, the structure of this embodiment can avoid this problem.

[0032] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
