AI Technical Summary

Technical Problem

Existing car seats lack the ability to both tilt the seat forward and lower the seat cushion, resulting in a step difference when the second and third rows of seats in a seven-seater vehicle are folded down, making it difficult to meet space requirements.

Method used

By designing a car seat that combines a backrest motor, a cable motor, and a lead screw motor, the seat can tilt forward and the cushion can sink. The entire system is controlled electrically by using a linkage mechanism and a motor drive.

Benefits of technology

The seats are electrically adjustable, eliminating step differences and meeting the space requirements of the second and third rows of seats in a seven-seater vehicle when they are folded down, making it easier to place luggage.
