Adjustable fixing device for car seat headrest

Abstract

The invention discloses an adjustable fixing device for a car seat headrest. The headrest is provided with an insertion rod, and at least two radial bumps are circumferentially distributed on the insertion rod. The adjustable fixing device includes an insertion pipe used for the insertion of the insertion rod, and a plurality of grooves are formed in the open end of the insertion pipe and matched with the bumps. The adjustable fixing device is characterized in that the adjustable fixing device further includes two movable pieces respectively located on the two sides of the headrest, a rotating shaft perpendicularly connected with the two movable pieces, and a driving device driving the rotating shaft to drive the two movable pieces to rotate; limiting devices are further respectively arranged on the sides of the two movable pieces and can limit the clockwise and the anticlockwise rotation angles of the movable pieces; the insertion pipe is fixedly arranged on the rotating shaft, and can rotate along with the rotating shaft. The adjustable fixing device for the car seat headrest, provided by the invention, has the advantages that the rotation angle of the headrest mounted on the rotating shaft can be controlled through the fit between the movable pieces and the limiting devices; the structure is simple, and the cost is low; the headrest can be adjusted independently, so as to achieve higher humanization.

Description

technical field [0001] The invention relates to an adjusting device, which belongs to the technical field of mechanical structures. Background technique [0002] With the development of modern society, automobiles have become more and more popular as a means of transportation. As an important component of the car interior, car seats provide drivers and passengers with a comfortable and safe driving and riding environment. Among them, the front and rear angle of the car seat can be adjusted as an essential function. Through adaptive adjustment, each driver and passenger can obtain a comfortable riding angle as much as possible, and at the same time, it can also ensure the safety of the driver's driving operation. In addition, the seat is usually provided with a headrest to increase the comfort of the driver and passengers, but the existing car seat headrests usually cannot adjust the angle independently, and the degree of humanization is not enough.
