Automobile seat backrest lock capable of achieving multi-gear angle adjustment

Abstract

The invention relates to an automobile seat backrest lock capable of achieving multi-gear angle adjustment, which comprises an upper cover and a lower cover, a mounting area is arranged between the upper cover and the lower cover, and a pawl, a pawl linkage column and a reset torsion spring are arranged in the mounting area. The automobile seat backrest lock is characterized in that the pawl is provided with a plurality of groups of gear bayonets capable of being linked with a seat latch hook; the gear bayonets are distributed on one side of the pawl and sequentially arranged from the hinged end of the pawl and the pawl linkage column to the other end, and lock holes are formed in the upper cover and the lower cover; the other end, opposite to the end provided with the gear bayonets, of the pawl is in linkage with a transmission plate, and the transmission plate is in linkage with an inhaul cable assembly. The automobile seat backrest lock has the beneficial effects that the automobileseat backrest lock capable of achieving multi-gear angle adjustment is provided, the comfort of an automobile seat is improved, the size is small, the weight is light, the installation space is small, and the concept of automobile light weight is met.

Description

technical field [0001] The invention relates to the technical field of backrest locks, in particular to a car seat backrest lock capable of multi-gear adjustment. Background technique [0002] For car seats, my country's regulations GB15083-2006 and GB9167-2006, which were implemented in February 2007, involve the provisions on preventing the moving luggage in the luggage compartment from injuring members and the strength of seat belts during car collisions. The regulations give corresponding specifications to the rear seat backs and headrests of most vehicles that constitute the luggage compartment and the three-point seat belts. cause harm to members. [0003] Existing car seats can be adjusted at multiple angles except for the front seats located in the driving area, and the rear seats cannot be adjusted at angles, and the multi-angle adjustment of the front seats mainly depends on the recliner. This function cannot be realized alone, most of them only have a first-spee...

AI Technical Summary

Problems solved by technology

[0003] Existing car seats can be adjusted at multiple angles except for the front seats located in the driving area, but the rear seats cannot be adjusted at multiple angles, and the multi-angle adjustment of the front seats mainly depends on the recliner, and the backrest lock This function cannot be realized alone. Most of them only have a first-speed locking function, and the angle cannot be adjusted during use. It cannot meet the above-mentioned requirements for the rear seats of the car and the needs of different customer groups. Therefore, it is improved for the backrest lock. It is necessary to enable multi-angle adjustment of rear car seats

[0004] And in the traditional backrest lock, the pawl is directly subjected to the force from the car seat lock hook, the reset torsion spring, and the cable assembly. After a long time of use, the pawl is prone to breakage, deformation and other adverse conditions, shortening the pawl service life
