Automobile seat headrest

Abstract

The invention discloses a car seat headrest, which comprises a front cover assembly, a rear cover assembly and a connection assembly, the connection assembly is used to connect the front cover assembly and the rear cover assembly; The connection assembly includes a turning body and a base, the turning body is installed in the front cover assembly, the base is installed in the rear cover assembly, the turning body and the top of the base Connected by a rotating shaft, the overturning body is provided with a plurality of locking teeth, and the base is equipped with pawls, and when the turning body rotates around the rotating shaft, the pawls cooperate with the plurality of locking teeth It is used to lock the turning body on multiple locking positions. Since the headrest can be locked at multiple card positions when the headrest is flipped back and forth, the angle and range of the flip adjustment are stable. In addition, because the headrest is divided into three parts, the front cover assembly, the rear cover assembly and the connection assembly, when the headrest is turned back and forth, no uncontrollable wrinkles will appear.

Description

technical field [0001] The invention relates to the field of car seats, in particular to a car seat headrest. Background technique [0002] In the current market, the six-way headrest only uses the PIP process (foaming process, that is, the foam material is directly filled into the sewn cover, and the molding is completed at one time). Due to the process, it can only pass The cooperation of the rotating shaft and the clip is used to realize the front and rear flip adjustment of the front half of the headrest and the front and rear flip adjustment of the side wing lugs. [0003] Such products have obvious disadvantages, that is, the flipping function is unstable and the appearance is exquisite and the workmanship is poor. The instability of the turning function is manifested in the fact that the operating force range of the front and rear turning adjustment of the front half of the headrest and the front and rear turning adjustment of the side wing lugs are unstable, with la...

AI Technical Summary

Problems solved by technology

[0003] Such products have obvious disadvantages, that is, the flip function is unstable and the appearance is exquisite and the workmanship is poor.

The instability of the turning function is manifested in the fact that the operating force range of the front and rear turning adjustment of the front half of the headrest and the front and rear turning adjustment of the side wing lugs are unstable, with large fluctuations, and there is no locking function for the front and rear turning adjustment of the front half of the headrest, which will bring users a lot of trouble. The bad experience of operating force is too large or too small, and even the risk of accidental return during use

However, the form of the hinge clip is too elementary to realize the different operating forces (differential torque) of the front and rear flip movements of the wing lugs.

Exquisite appearance and poor workmanship The specific performance is that this kind of six-way headrest can only be guaranteed to have a good appearance in the design position (non-use position) (the cover has no uncontrollable wrinkles, etc.), once the front half of the headrest is used, it can be turned back and forth to adjust And the function of flipping back and forth of the side ear pieces, that is, the problem of uncontrollable irregular face cover folds and poor appearance
