Components of a car seat system

Car seat is one of the important structures in the interior of a car, and the seat is composed of a frame, seat cushion, backrest and adjustment mechanism. The seat cushion and backrest should have some elasticity. The adjustment mechanism can move the seat forward and backward or up and down, adjusting the reclining angle of the seat cushion and backrest. Some seats also have elastic suspension and shock absorbers that can be adjusted to ensure that the seat cushion is at the right height above the ground for the driver's different body weights. Some truck cabs and buses also have sleepers suitable for long-distance driving at night.
