Problems solved by technology

However, due to the limitation of the technology level, the domestic headrest struts are mostly made of steel rods, which are of high quality. The weight of a strut is about three times that of the struts made of steel pipes abroad. The material waste is large and the cost is high.

Abstract

The invention relates to a lightweight fulcrum bar of a headrest of an automobile, which comprises a supporting portion, a connecting portion and an adjusting guiding portion. The adjusting guiding portion consists of two bilateral steel tubes, the front end of the adjusting guiding portion is connected with the connecting portion, the connecting portion comprises two bilateral bent steel tubes, the two bent steel tubes are respectively connected with the two steel tubes of the guiding adjusting portion, the supporting portion is a bilateral U-shaped steel tube, and lower ends of two supporting legs of the U-shaped steel tube are respectively connected with upper ends of the two steel tubes of the guiding adjusting portion. The lightweight fulcrum bar of the headrest of the automobile is simple in structure, light in weight, high in material strength and low in material consumption, and cost can be saved.

Description

technical field [0001] The invention relates to the field of auto parts, in particular to a light-weight automobile headrest strut. 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, and safety is its most important function. When the rear of a passenger car is hit, the head of the occupant will move to the rear with the inertia. In a short period of time, the forces of acceleration and deceleration are all squeezed on the fragile neck. At this time, the passive protection of the headrest plays an important role. The function of cushioning and energy absorption protects the occupant's head and cervical spine from all sides. However, due to the limitations of the technology level, the domestic headrest struts are mostly made of steel rods, which are of high quality. The weight of a strut is about three times that of the struts made of steel pipes abroad, resulting in a...
