Abstract

The invention relates to an active headrest with a hinge structure, which comprises a front cover of the headrest and a rear cover of the headrest. The middle upper part of the front cover of the headrest and the rear cover of the headrest is equipped with a hinge ejection system; A pole fixing and activating system is provided under the ejection system; a rack locking system is provided between the hinge ejection system and the pole fixing and activating system; the pole fixing and activating system is composed of a pole and a cable; The cable is located between the seat back and the hinge ejection system; the strut is fixed on the seat frame; the rack locking system is composed of a fixed rack and a movable rack; the The headrest front cover is made of energy-absorbing material. The invention makes it possible for the active headrest to instantly rise and tilt forward in order to protect the head when the passenger car collides, and the distance between the occupant's head and the headrest is reduced at the moment of collision, thereby greatly reducing the The turning angle of the head of the small occupant reduces or eliminates whiplash on the occupant's neck.

Description

technical field [0001] The invention belongs to the technical field of passenger car headrests, in particular to an active headrest with a hinge structure. Background technique [0002] The function of the passenger car headrest is generally an auxiliary device set up to improve the comfort and safety of the car. Among them, security is mainly passive protection. When the rear of a passenger car is hit, the occupant's head will move to the rear with inertia. In a short period of time, when the forces of acceleration and deceleration are all squeezed on the fragile neck, the occupant's cervical spine will suffer relatively large injuries. The deficiencies in the passive safety protection of the headrest are: firstly, the headrest has a certain distance from the head of the occupant, and when it is impacted, it cannot play a protective role when the head starts to move; On the chair, when the head touches the headrest, the acceleration force is still very large, and the pro...
