Headrest structure which can be controlled to overturn through press button or pull rope

Abstract

A headrest structure which can be controlled to overturn through a press button or pull rope comprises a headrest rod detachably fixed to the top of a seat and a frame body capable of rotating with respect to the headrest rod, wherein the frame body is arranged on a top cross rod at the top of the headrest rod, a mounting base used for the top cross rod to penetrate and capable of overturning together with the frame body is arranged in the lower portion of the frame body, a limiting chuck is fixed to the top cross rod located in the mounting base, a turnover mechanism capable of keeping downward turnover of the mounting base under the external-force-free effect is arranged on the mounting base, a limiting mechanism which can be fastened with the limiting chuck and can also disenable positioning through the pull rope or the press button so as to make the mounting base overturn after the mounting base is positioned is arranged in the mounting base, the pull rope extends out of a headrestthrough the inner cavity of the headrest rod, and the button end of the press button is located on the side face of the frame body. The headrest structure has the advantages that the turnover mechanism can make the frame body overturn downward by adopting a structure of pulling the pull rope or pressing the press button, response is sensitive, the structure is simple in operation and also saves effort, and the service life of the headrest is effectively prolonged.

Description

technical field [0001] The invention relates to the technical field of automobile headrest production, in particular to a headrest structure capable of being turned over by buttons or drawstrings. Background technique [0002] A Chinese invention patent application with the application number CN201710605354.2 titled "Rope Pull Button Car Headrest" discloses a cord pull button car headrest, which includes a pillow rod, a frame that can rotate relative to the pillow rod, and a frame body It is arranged on the top cross bar at the top of the pillow rod, and a limit block is set in the inner cavity of the frame body, and the limit block is fixed with the top cross bar. One end of the return torsion spring is connected with the limit block, and the other end of the return torsion spring touches the side wall of the frame body, and the inner cavity of the frame body is provided with a limit part that can be buckled with the limit block. The body is provided with a drawstring thro...

AI Technical Summary

Problems solved by technology

However, the frame body of the automobile headrest needs to be designed with different shapes of mounting recesses and protrusions, which is inconvenient to process, and the frame body needs to be replaced as a whole after damage, and the production cost is high, so the structure of the automobile headrest needs further improvement
