Abstract
Description
Technical Field
[0001] This invention relates to the field of automotive technology, and in particular to a rear seat back unlock handle. Background Technology
[0002] Currently, when car rear seats use split backrests with backrest locks, a backrest adjustment handle is required. The structure of this handle affects operational comfort. Existing backrest adjustment handles consist of a housing and a pressing handle, fixed to the backrest frame. This pressing method results in a small operating area, difficulty in applying force, and poor operational comfort. Furthermore, after locking the backrest, the button has no indicator, requiring manual shaking of the backrest to confirm the locking status.
[0003] Therefore, there is an urgent need to design a rear seat back unlock handle that can overcome the above problems. Summary of the Invention
[0004] The technical problem to be solved by the present invention is to provide a rear seat back unlock handle, which overcomes the above-mentioned defects of the prior art. It adopts a pulling method, which is easy to use and comfortable to operate; the button has a color display on the upper surface, which makes it easy to confirm the backrest locking status.
[0005] The technical problem to be solved by the present invention is achieved through the following technical solution:
[0006] A rear seat back unlock handle, comprising:
[0007] The outer shell has its upper end snapped into the U-shaped groove of the seat frame by an L-shaped boss, and its lower end is fixed to the seat frame by bolts. A rectangular hole is provided on the rear side of the outer shell.
[0008] The handle includes an upper end piece, a lower end piece, a pivot, and an unlocking pull wire. The upper end piece can pass through the rectangular hole and is movably connected to the housing. The two ends of the pivot are respectively engaged in the pivot holes on both sides of the housing. The unlocking pull wire is connected to a steel wire.
[0009] The handle cover includes a groove, the lower surface of which contacts the lower end piece. Clips are provided on both sides of the handle cover, and the clips engage with side openings on both sides of the outer shell.
[0010] Preferably, in the above technical solution, the outer shell is provided with an accommodating space, the handle is disposed in the accommodating space, and the handle cover is disposed above the outer shell and closes the accommodating space.
[0011] Preferably, in the above technical solution, the lower surface of the outer shell is provided with a bottom opening, and the top end of the steel wire passes through the bottom opening and is connected to the unlocking pull wire.
[0012] Preferably, in the above technical solution, the upper end piece and the lower end piece are connected by a U-shaped groove, and the upper end piece and the lower end piece are two arc-shaped structures with the same center.
[0013] Preferably, in the above technical solution, a red layer is provided on the upper end piece.
[0014] Preferably, in the above technical solution, when the unlocking wire rotates under the drive of the steel wire, the groove and the front end of the outer shell are both used to limit the lower end piece.
[0015] The above-described technical solution of the present invention has the following beneficial effects:
[0016] The rear seat back unlock handle of this application adopts a pull-type unlocking method, which is easy to use and comfortable to operate, avoiding the problems of small operating area, difficulty in applying force, and poor operating comfort of traditional press-type handles; the button has a color display on its upper surface to make it easy to confirm the backrest locking status.

[0026] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that, unless otherwise specifically stated, the relative arrangement, numerical expressions, and values of the components and steps set forth in these embodiments do not limit the scope of the invention.
[0027] like Figures 1-7 As shown, a rear seat back unlock handle includes: a housing 1, a handle 2, and a handle cover 3. Details are as follows:
[0028] The upper end of the outer shell 1 is snapped into the U-shaped groove of the seat frame by an L-shaped boss 11, and the lower end of the outer shell 1 is fixed to the seat frame by bolts 12. A rectangular hole 13 is provided on the rear side of the outer shell 1.
[0029] The handle 2 includes an upper end piece 21, a lower end piece 22, a rotating shaft 23, and an unlocking pull wire 24. The upper end piece 21 can pass through the rectangular hole 13 and be movably connected to the outer casing 1. The two ends of the rotating shaft 23 are respectively engaged in the rotating shaft holes on both sides of the outer casing 1. The unlocking pull wire 24 is connected to the steel wire 4.
[0030] The handle cover 3 includes a groove 32, the lower surface of which contacts the lower end piece 22. Both sides of the handle cover 3 are provided with clips that engage with the side openings on both sides of the outer shell 1.
[0031] In other words, the outer casing 1 has a receiving space, the handle 2 is located in the receiving space, and the handle cover 3 is located on top of the outer casing 1 and closes the receiving space.
[0032] Furthermore, a bottom opening is provided on the lower surface of the outer casing 1, and the top end of the steel wire 4 passes through the bottom opening and is connected to the unlocking pull wire 24.
[0033] Furthermore, the upper end piece 21 and the lower end piece 22 are connected by a U-shaped groove, and the upper end piece 21 and the lower end piece 22 are two arc-shaped structures with the same center. Moreover, the two are an integral structure.
[0034] Furthermore, a red layer is provided on the upper end piece 21. The upper end of the handle 2 is marked with red through two-color injection molding. Pulling up the handle 2 unlocks the seat back, and the red mark is revealed by the rotation of its own shaft driven by the unlocking pull, serving as a reminder.
[0035] Furthermore, when the unlocking pull wire 24 rotates under the drive of the steel wire 4, both the groove 32 and the front end of the outer shell 1 are used to limit the lower end piece 22. The handle 2 rotates forward at a controllable angle under the action of the unlocking pull wire, and is limited by interference when rotating backward. The rectangular groove of the upper cover 3 serves two purposes: firstly, to provide space for hand operation, and secondly, to cover the gap after the handle 2 rotates. The upper cover 3 and the foam need to interfere with each other by 2.5mm, i.e., the upper cover material is thick, to avoid gaps between the plastic parts and the soft foam.
[0036] The method of using (working process) of the rear seat back unlock handle of this application is as follows:
[0037] The latch 2, via the steel wire 4 and the spring on the backrest lock, unlocks the backrest lock tongue. During unlocking and locking, the latch 2 rotates within the housing via a pivot. In the unlocked state, a red indicator is exposed; in the locked state, the red indicator is hidden.
[0038] Although the present invention has been disclosed above with reference to embodiments, it is not intended to limit the present invention. Any person skilled in the art can make various different choices and modifications without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention is defined by the claims and their equivalents.
