Noiseless automobile headrest capable of stretching and retracting up and down

Abstract

A noiseless automobile headrest capable of stretching and retracting up and down comprises a headrest rod capable of being arranged at the top of an automobile seat and a headrest frame shell capableof moving up and down along the headrest rod. The top of the headrest rod extends into the headrest frame shell. The noiseless automobile headrest is characterized in that a locking sheet capable of being buckled in grooves in the sides of the headrest rod and an unlocking block capable of pushing the locking sheet to be separated from the grooves are arranged in an inner cavity of the headrest frame shell, one end of the unlocking block is in linkage with a button transversely extending into the inner cavity of the headrest frame shell, one end of the locking sheet abuts against the unlockingblock, the other end of the locking sheet is connected with the inner wall of the headrest frame shell through a reset device, and a noise elimination structure capable of eliminating noise when thelocking sheet is clamped in the corresponding grooves is further arranged between the locking sheet and the corresponding grooves. The noiseless automobile headrest has the beneficial effects that thestructure is simple, unlocking efficiency is high, labor is saved in the unlocking process, a locating effect is good, and use is quite convenient; unlocking and locating synchronism is good, the headrest ascends and descends smoothly, and the situation that the headrest is stuck is avoided; and the noise elimination structure can eliminate the noise generated when the locking sheet is clamped inthe corresponding grooves.

Description

technical field [0001] The invention relates to the technical field of car seat manufacture, in particular to a noiseless car headrest capable of stretching up and down. Background technique [0002] An existing Chinese utility model patent with the application number CN201120546009.4 titled "Extensible Automobile Headrest" discloses a telescopic automobile headrest, which includes a pillow body and a pillow rod. The upper part of the pillow rod extends into the pillow The body and the pillow body are fixed together, and it is characterized in that: the pillow rod can be telescopically arranged in the pillow frame, the pillow body is sleeved on the outer surface of the pillow frame, and the pillow frame is provided with a bolt capable of fixing the pillow rod. Telescopic control mechanism; the telescopic control mechanism includes a spring rod, one end of the spring rod is fixed to the inner wall of the pillow frame, the other end of the spring rod extends out of the pillow ...

AI Technical Summary

Problems solved by technology

However, the spring rod of the automobile headrest adopts elastic deformation to be fixed with the pillow rod, and it is easy to occur that one side is separated from the other side and the other side is still not separated, resulting in the expansion and contraction of the headrest and jamming, which is inconvenient to use. Therefore, the automobile headrest The structure needs to be further improved
