Safety head restraint device for actively buffering automobile collision

Abstract

The invention provides a safety head restraint device for actively buffering automobile collision. A supporting column is hinged at one end of a leaning rod; the other end of the leaning rod is fixedly arranged on a cylinder body at one end of a buffering supporting cylinder; a buffering supporting piston rod is arranged in the other end of the buffering supporting cylinder; the buffering supporting piston rod is fixedly arranged on an auxiliary supporting seat; and the auxiliary supporting seat is fixedly arranged at the upper end of a chair back. According to the invention, through the adoption of the buffering supporting cylinder, a buffering supporting effect is realized on the head restraint in the automobile collision process; as various elastic energy absorbing bag bodies are arranged in the head restraint, the collision energy can be first preferably absorbed; and as a buffering bracket is arranged at the back end of the active safe head restraint device, the collision energy can be further absorbed to reduce damages to heads of drivers. In addition, through the adoption of a cam and a locking pin, an auxiliary supporting rod can extend out of the head restraint at the moment of collision and is supported on the auxiliary supporting seat, an adverse consequence that the head restraint is tilted backward is prevented.

Description

technical field [0001] The invention relates to the technical field of safety headrests for automobile collisions, in particular to an active safety headrest device for automobile collisions, which belongs to the technical field of automobile parts. Background technique [0002] The car headrest is a kind of driving comfort configuration product and safety protection product. When a vehicle collides with the rear, 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 acts as a buffer to protect the human head. Car headrests are one of the national compulsory certification and testing items for complete vehicles. There are strict regulations on material, strength, energy absorption, position and size. Even if the vehicle speed is only 10km / h, in the event of a collision, the acceleration and deceleration forces of the vehicle will al...

Problems solved by technology

However, the current active collision safety headrest has poor energy absorption and limited cushioning effect. Moreover, in a collision, the headrest is easy to tilt backward under the action of force, thus failing to provide protection to the head. Protective effects
