Background

A car seat is a seat that sits when sitting on a car, and can be roughly classified into: front row seat: headrest, backrest, cushion and armrests, and the back-row seats (headrest, backrest, cushion, side wings and armrests), the average price of the general car seat is about $850-1050, the average price of the middle-grade car is about $1400-1600, and the upper-grade car exceeds $2000. For most passenger cars, the seat is more expensive than the gearbox, chassis and body.

Ordinary car seats generally do not have the requirement of damping, and the suspension system of vehicle chassis can play better damping effect, and to freight train or large-scale passenger train, the driver generally need carry out long-time driving, and the distance is farther between automobile body chassis and the seat, so the damping on chassis can not directly act on the seat, this just leads to freight train or large-scale passenger train seat to vibrate along with the automobile body when passing through rugged road surface, therefore perhaps the seat of large-scale passenger train needs to be equipped with the shock absorber in order to play the effect that promotes driver's travelling comfort.

The traditional seat shock absorber mainly realizes the shock absorption by the cooperation of the shock absorption spring and the damper, but the mode can not adapt to the use requirement of a driver, and can not adjust the shock absorption effect according to the actual road surface condition, so that the seat shock absorber has larger limitation in use and influences the use feeling of the driver.
