Description

Technical Field

[0001] The utility model relates to the technical field of automobile headrests, in particular to an automobile headrest frame folding component. Background Art

[0002] The car headrest is a driving comfort configuration and safety protection product, usually made of semi-rigid polyurethane foam plastic, and takes into account both safety and comfort in terms of shape, height, size, etc. The main function of the car headrest is that when a vehicle rear-end collision occurs, the human body will fall backward due to inertia. At this time, the pressure of vehicle acceleration or deceleration is concentrated on the fragile neck and head of the human body, and the headrest plays a buffering role to protect the human head. The car headrest frame is an important part of the headrest structure, which provides support and stability for the headrest.

[0003] A common automobile headrest frame is generally composed of two mutually parallel assembly rods, and the headrest is installed on the top of the seat through the assembly rods. However, since the assembly rods can only drive the headrest to adjust up and down in this way, the headrest cannot be folded at a large angle, which reduces the convenience and practicality of the headrest and cannot meet the working requirements of the automobile headrest. Therefore, a car headrest frame folding component is proposed. Utility Model Content
