Description

Technical Field

[0001] The utility model relates to the technical field of automobile headrests, in particular to an automobile headrest which is easy to disassemble and clean. Background Art

[0002] The headrest of a car seat is also called a backrest. It is an auxiliary device set up to improve the comfort and safety of the car. The car headrest is divided into two types: fixed and movable. In a low-back seat, the headrest and the backrest are detachable. The headrest is a separate object, which is inserted into the socket of the seat back with a single or double pin and fixed on the backrest. This low-back seat is mostly used in passenger cars;

The disassembly and adjustment mechanism arranged on the top surface of the seat back cooperates with the use of the headrest body. When the headrest body needs to be disassembled and cleaned, the C-shaped rod is manually pulled to drive the movable plate to move forward inside the inner cavity through the slider, and the movable plate moves along the fixed rod through the connecting hole to force the compression spring to retract, so that the limiting rod on the rear end wall of the movable plate is no longer inserted in the adjustment hole to limit the height of the headrest body after adjustment, and the insertion rod on the bottom surface of the headrest body is pulled out from the insertion hole on the top surface of the seat back, so as to facilitate the user to quickly disassemble the headrest body from the top surface of the seat back for cleaning, and the disassembly operation is simple and convenient, and the height of the headrest body can be adjusted by using the disassembly and adjustment mechanism in conjunction with the adjustment hole on the insertion rod;
