Abstract

The invention discloses vehicle seat sponge, a manufacturing method, a module and a vehicle seat. The vehicle seat sponge comprises a main functional area, wherein a left supporting area and a right supporting area are respectively arranged on the two sides of the main functional area, the main functional area sequentially comprises a front area, a middle area and a back area from the front to the back, the density of the middle area is 60-70 gram per cubic meter, the density of the front area is 45-55 gram per cubic meter, and the density of each of the left supporting area, the right supporting area and the back area is 40-50 gram per cubic meter. The vehicle seat sponge has the characteristics of being multiple in density and hardness, the position which needs to be supported has better supporting performance, the position which needs to be soft has good buffering performance and attaching performance, when a vehicle swerves, the area with the two sides being hard can reduce horizontal accelerated speed borne by a human body, so that the hip and the thighs of the human body can lightly bear the body, the horizontal stability of the human body is guaranteed, and the comfort and the safety are good.

Description

technical field [0001] The invention belongs to the technical field of car seats, relates to a car seat sponge, and also relates to a preparation method of the car seat sponge, a mold for preparing the car seat sponge and a car seat using the car seat sponge . Background technique [0002] Car seat sponge is an important part of the car seat, which is directly related to the comfort of the driver and passengers in the car. At present, polyurethane sponges for automobiles are single-density and single-hardness sponge products. The mechanical properties of commonly used MDI system seat sponges are as follows: 25% indentation hardness is (150±20)N, 65% indentation hardness is (390±20)N )N, the density is (50±5)g / m 3 . Although this sponge satisfies the requirements of riding to a certain extent, this product cannot meet the comfort requirements of passengers at present. If the car seat sponge is harder, it will make people uncomfortable to ride, and it will make the occupan...
