Abstract

The invention provides a seat, a vehicle body comfort system and a vehicle, and relates to the field of vehicle seats, wherein the seat comprises a seat plate and a seat underframe; the bottom of the seat plate is fixedly provided with a plurality of seat brackets, the bottom of each seat bracket is provided with a pulley, the concave surface of the seat bottom frame is provided with a plurality of transverse slideways, the pulleys are in sliding connection with the transverse slideways, the central pulley is in sliding connection with the central slideways, the central pulley is positioned in the concave part under the preset condition, and the top of the central seat bracket is fixedly connected with the central position of the bottom of the seat plate through elastic equipment. When the centrifugal force is large, the pulley slides to one side of the centrifugal force direction to drive the seat plate to do small circular motion. The seat underframe applies a transverse force opposite to the centrifugal force to the seat plate, so that adverse effects of personnel caused by the centrifugal force are damped and even offset, and the probability of personal injury of the personnel is reduced. The seat realizes vibration reduction of the transverse direction, the vertical direction and the centrifugal force on the whole.

Description

Seat, car body comfort system and car Technical Field The invention relates to the field of vehicle seats, in particular to a seat, a vehicle body comfort system and a vehicle. Background In order to improve safety and riding comfort, most seats used on the existing vehicles are provided with safety airbags and damping equipment, and the seats of higher levels have functions of electric adjustment, heating ventilation massage and the like, and also have the function of damping vibration in three directions of longitudinal, transverse and vertical directions. Although the existing seat has better vibration reduction to the three directions of longitudinal direction, transverse direction and vertical direction, for the centrifugal force generated by centrifugal acceleration when the vehicle is over-bent, particularly, when the vehicle is over-bent rapidly, larger centrifugal force can be generated, even if the safety belt is fixed, people on the seat can still tilt or move towards the direction of the centrifugal force, and even when the safety belt is serious, the people can be damaged due to the excessive centrifugal force, so that personal safety is endangered.
