Abstract

The invention discloses a car seat backrest angle control system. The system comprises a direct impact acceleration sensor, a side impact acceleration sensor, a rear impact acceleration sensor, an angle displacement sensor which is used for detecting the angle of a seat backrest, a control unit and a drive device which is used for providing a driving force to rotate the seat backrest, wherein thedirect impact acceleration sensor, the side impact acceleration sensor, the rear impact acceleration sensor, the angle displacement sensor and the drive device are connected with the control unit. According to the system, a passenger can quickly adjust an abnormal sitting posture to a normal sitting posture when impact happens, the passenger protection performance can be promoted, and the risk ofhurting passengers can be reduced.

Description

technical field [0001] The invention belongs to the technical field of car seats, and in particular, the invention relates to a car seat back angle control system and a control method thereof. Background technique [0002] At this stage, except for the US market, my country and even Europe have not considered the protection design of occupants in abnormal sitting positions. Due to the inability to give full play to the protective effect of the car safety system, any form of collision may cause fatal injuries to occupants in abnormal sitting positions (especially lying positions); therefore, within 50ms of the collision (the specific seat reset time needs to / side / rear collision conditions) Correcting the occupant's sitting posture is very important to improve occupant protection performance. [0003] The safety products and occupant peripheral parts on existing cars are designed based on the occupant sitting posture in the normal design state, without considering the occupa...
