Automobile vibration attenuation seat

Abstract

The invention discloses an automobile vibration attenuation seat which comprises a backrest, a cushion connected to the lower end of the backrest and a supporting seat for supporting the cushion. The backrest and the cushion are both manufactured by filling sponge with slow rebound mechanical property into leather layers; a high-density sponge insert is arranged in the middle above the cushion; a vibration-proof pad is arranged below the cushion; an elastic assembly is arranged below the vibration-proof pad and is of a screen frame structure defined by a plurality of springs. According to the automobile vibration attenuation seat, the high-density sponge insert is additionally arranged at the position where the hip and the cushion contact, deformation of the position contacting with the hip is reduced, and vibration amplitude of passenger bodies is reduced; the vibration-proof pad and the elastic assembly of the screen frame structure are arranged at the bottom of the cushion and have excellent anti-vibration performance, the resonance ratio and accelerated speed are corresponding, the passengers can be avoided from vibration with high vibration amplitude, the hip can be supported firmly, rotation of the pelvis and bending force applied to the spine can be reduced as far as possible, and comfort of the passengers can be improved greatly.

Description

technical field [0001] The invention relates to a seat, in particular to a shock-absorbing car seat. Background technique [0002] Traditional car seats generally use springs and (or) foam plastics for vibration damping, but this vibration damping material itself has some shortcomings: the foam plastic block has poor air permeability, and it makes people feel irritable and uncomfortable in hot summer, and the general driver's seat The springs used have small damping, poor cushioning effect, and high rebound force. The seat cushion is soft and prone to fatigue after long-term riding, which increases the rotation of the pelvis and the bending force acting on the spine, especially when the car is driving on uneven roads. The bumps are severe, which is more likely to cause fatigue and motion sickness. Contents of the invention [0003] In view of the above-mentioned technical problems, the object of the present invention is to provide a car seat with reasonable design, good r...
