Description

Technical Field

[0001] The present application relates to the technical field of backrest support frames, and in particular to a backrest extension support frame for rear seats of automobiles. Background Art

[0002] The rear seat backrest of the car is mostly fixed by installing locking rings on the C-pillars on both sides of the seat backrest to bear the force of the entire backrest. The existing locking ring is a fixed structure, usually composed of a locking ring and a locking seat. The locking ring is "U" shaped, and the two ends of the locking ring are fixed on the locking seat, and are fixed to the C-pillar through the locking seat.

[0003] Therefore, the backrest angle of most rear seats in cars is fixed when they leave the factory and cannot be adjusted. Everyone has different feelings of comfort caused by the backrest tilt angle, which cannot meet the needs of users. For this reason, our company has developed and produced an extended support frame for the backrest of rear seats in cars. Utility Model Content

[0004] In order to solve the above technical problems, the present application provides a rear seat backrest extension support frame for a car, which has the advantages of being able to meet the backrest angle adjustment and fixation requirements, and at the same time having the advantages of high structural strength and small space occupancy.

[0005] In order to achieve the above object, the technical solution of the utility model is as follows:

[0017] The implementation of the above technical solution, i.e. the provision of the reinforcement portion, can ensure that the overall width of the expansion board is the shortest and still has a certain width margin, thereby ensuring the overall structural strength of the expansion board.

[0018] As a preferred solution of the present application, two lower positioning holes are provided, and the two lower positioning holes are arranged horizontally, and two upper positioning holes are provided, and the two upper positioning holes are arranged vertically.

[0019] By implementing the above technical solution, the entire expansion part is fixed and locked by dispersed screws, and when the locking seat is subjected to force, the upper and lower positioning holes arranged horizontally and vertically can disperse and weaken the rotational torque of the screws passing therethrough, thereby ensuring the stability of the expansion board.

[0020] As a preferred solution of the present application, the locking seat includes a U-shaped positioning frame. A reinforcing plate is provided at the connection between the U-shaped positioning frame and the expansion plate.

[0021] The above technical solution is implemented so that the reinforcing plate can play a role in fixing the overall structural strength of the U-shaped positioning frame, while increasing the welding area between the locking seat and the expansion plate, thereby ensuring the connection strength between the locking seat and the expansion plate.

[0032] The following is combined with Figure 1-3 This application is described in further detail.

[0033] Embodiment 1

[0034] The present application discloses a rear seat backrest extension support frame for a vehicle. Figure 1 A rear seat backrest expansion support frame for a car comprises an expansion plate 1 and a locking seat 2 arranged on the expansion plate 1.

[0035] The expansion board 1 includes a bottom support portion 11 and a top positioning portion 12. The bottom support portion 11 and the top positioning portion 12 are arranged relatively tilted as a whole. The lateral width of the bottom support portion 11 gradually decreases in the direction close to the top positioning portion 12, thereby reducing the overall size and floor space of the expansion board 1, thereby facilitating personnel to install the expansion board 1 on the vehicle. Moreover, because the lateral width of the bottom support portion 11 gradually decreases in the direction close to the top positioning portion 12, while the size of the bottom support portion 11 is reduced, its stability can be guaranteed (forming a "triangle"). The buckle seat 2 is arranged on the top positioning portion 12, so that by setting the position and tilt angle of the buckle seat 2 on the top positioning portion 12, the backrest tilt angle can be changed after the seat backrest is locked on the buckle seat 2, thereby meeting the use needs of the personnel. The position of the buckle seat 2 can also be modified to meet the needs of different users.

[0036] The bottom support portion 11 is provided with a plurality of lower positioning holes 13 for connecting with the car. In this embodiment, there are two lower positioning holes 13, which are horizontally arranged at both ends of the lower edge of the bottom support portion 11, so that the bottom support portion 11 can be screwed through the lower positioning holes 13 and then screwed on the car frame, thereby completing the locking and fixing of the bottom support portion 11, and the distance between the two lower positioning holes 13 can be set according to the distance between the reserved holes of the car itself. The top positioning portion 12 is provided with a plurality of upper positioning holes 14 for fixed connection with the car, and there are two upper positioning holes 14, which are arranged vertically, that is, similar to the lower positioning holes 13, so that the top positioning portion 12 can be screwed through the upper positioning holes 14 and then screwed on the car frame, thereby completing the locking and fixing of the bottom support portion 11. The two lower positioning holes 13 are arranged horizontally and the two upper positioning holes 14 are arranged vertically, so that the entire expansion part is fixed and locked by dispersed screws, and when the locking seat 2 is subjected to force, the upper positioning holes 14 and the lower positioning holes 13 arranged horizontally and vertically make the rotational torque of the screws passing therethrough be dispersed and weakened, thereby ensuring the stability of the expansion board 1.

[0037] A U-shaped positioning groove 15 is provided on the top positioning portion 12 so that when the expansion board 1 is installed on the vehicle, the U-shaped positioning groove 15 can be stuck on the protrusion of the vehicle itself, thereby ensuring the accuracy of the installation position of the expansion board 1 and ensuring that the backrest lock can be accurately buckled on the lock seat 2.

[0038] An inwardly concave arc-shaped filtering portion 16 and an outer arc-shaped transition portion 17 are provided at the connection between the bottom supporting portion 11 and the top positioning portion 12. The setting of the inner arc-shaped transition portion can improve the tensile strength of the bottom supporting portion 11, and the setting of the outer arc-shaped transition portion 17 can improve the compressive resistance, thereby ensuring the overall structural strength of the expansion board 1 while reducing its space occupancy, ensuring that after it is installed on the original vehicle, it will not affect the normal use of the vehicle space.

[0039] The connecting edge between the top positioning portion 12 and the outer arc-shaped transition portion 17 is an arched setting (at A), so that as shown in the figure, when the locking seat 2 is subjected to force, the compressive resistance at A becomes higher, thereby ensuring the stability of the expansion board 1, and then the width of the expansion board 1 can be reduced to reduce the occurrence of space occupancy.

[0040] The bottom support portion 11 is provided with a reinforcing portion 18 connected to the outer arc-shaped transition portion 17, and the reinforcing portion 18 is provided protruding from the edge of the bottom support portion 11. That is, the provision of the reinforcing portion 18 can ensure that the overall width of the expansion board 1 is shortest and still has a certain width margin, thereby ensuring the overall structural strength of the expansion board 1.

[0041] The lock seat 2 includes a U-shaped positioning frame 21, and the cross section of the U-shaped positioning frame 21 is circular, which ensures its structural strength while allowing the lock on the backrest to be more easily buckled on the lock seat 2. A reinforcing plate 22 is provided at the connection between the U-shaped positioning frame 21 and the expansion board 1, so that the reinforcing plate 22 can fix the overall structural strength of the U-shaped positioning frame 21 and increase the welding area between the lock seat 2 and the expansion board 1, thereby ensuring the connection strength between the lock seat 2 and the expansion board 1.

[0042] Embodiment 2

[0043] The difference between this embodiment and the first embodiment is that: a telescopic sleeve 3 is hinged on the bottom support portion 11, a telescopic leg 4 is slidably arranged in the telescopic sleeve 3, and a locking screw 5 for locking the telescopic leg 4 is screwed on the telescopic sleeve 3, that is, the locking screw 5 is screwed to abut and press the telescopic leg 4, so as to achieve the locking and fixing of the telescopic leg 4. Two lower positioning holes 13 are respectively designed on the bottom support portion 11 and the telescopic leg 4, so that the position and angle of one of the lower positioning holes 13 can be adjusted to meet the installation requirements of different models.

[0044] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
