[0003] The seat is one of the important devices inside the car body. The seat is composed of a frame, a cushion, a backrest and an adjustment mechanism. The cushion and the backrest should have a certain degree of elasticity. The adjustment mechanism can move the seat forward and backward or up and down and adjust the inclination angle of the cushion and the backrest. Some seats also have elastic suspension and shock absorbers, and their elastic suspension can be adjusted to ensure that the height of the seat cushion from the floor is appropriate under the action of different driver weights. Car seats can be divided into split seats and long seats according to their shape; fixed, detachable and adjustable according to their function; single, double and multi-person chairs according to the number of passengers. According to the performance of the seats, they have developed from the earliest fixed seats to multi-functional power-adjustable seats.
