Description

Technical Field

[0001] The utility model relates to the technical field of automobile seats, in particular to a high-strength automobile seat frame. Background Art

[0002] In the process of manufacturing cars, car seats are also an indispensable part. The main function of car seats is to provide drivers and passengers with an easy-to-operate, comfortable, safe, and fatigue-free driving position. Car seats can be divided into long seats and split seats according to their shape, and can be divided into fixed, detachable, and adjustable types according to their function. Car seats should be comfortable, safe, durable, and reasonable.

[0003] At present, for the sake of comfort, the angle of the backrest of a car seat can be adjusted according to the user's needs when in use. In the prior art, if the car is subjected to a strong impact during driving, the fixed angle of the seat back of the car seat may be out of control, and the seat back cannot be fixed, resulting in an increase in the space for passengers to move their bodies. When impacted, it is easier for the passenger to fly out of the seat and cause injury. In addition, the existing seat frame does not have good protection measures for the passenger's head, and the passenger's neck is easily injured when the car is impacted. Utility Model Content
