Problems solved by technology

The first option seat is relatively heavy, expensive, not environmentally friendly, and has a low level of safety performance. It is difficult to pass the crash test requirements in the C-NAP regulations.
The overall seat is soft
The second option has improved the safety level, but it is not as soft and basically airtight as pure PU (polyurethane) overall, and the ride comfort is poor, and the safety level is not particularly high.
The processing cost of EPP body is high

Embodiment Construction

[0026] see figure 1 , figure 2 , the automobile rear seat cushion of the present invention, comprises sitting people area 1 and surrounding area 2, and each area all comprises cushion core and seat skin (seat skin is not shown); The seat cushion of sitting people area and surrounding area The core is composed of upper and lower layers of foam materials, and the upper and lower layers of foam materials are connected to each other through complementary structures (for coordination, see figure 2 ).

[0027] The upper layer 11 of the cushion core in the sitting area 1 is a low-density polyurethane foam material, and the lower layer 12 is a straw-shaped hollow polypropylene foam material with breathable and sound-absorbing functions. The density of the above-mentioned low-density polyurethane foam material is 50kg / m 3 .

[0028] The upper layer 21 of the cushion core in the surrounding area 2 is a high-density polyurethane foam material, and the lower layer 22 is a high-stren...

Abstract

The invention discloses an automobile back-row cushion. The automobile back-row cushion comprises a sitting area and a peripheral area, wherein each area comprises a cushion core and a seat fabric; the cushion cores of the sitting area and the peripheral area are constructed by an upper layer foaming material and a lower layer foaming material respectively; the upper layer foaming materials and the lower layer foaming materials are connected in an embedding way through a complementary structure. The machining-assembling method for the automobile back-row cushion comprises the following steps: making a polyurethane foaming material according to the shape of the upper layer of each cushion, making a polypropylene foaming material according to the shape of the lower layer of each cushion core, and assembling corresponding polyurethane foaming materials and polypropylene foaming materials into each cushion core respectively; coating integrally, and fixing the fabric with an injection-molded clamping bar; fixing the cushion on a vehicle metal plate through a dual-layer mushroom hasp. By adopting the automobile back-row cushion, the collision safety index is increased, the weight is reduced, the buffering performance is improved, the passenger comfort is improved, and a sound-absorbing function is realized.

Description

technical field [0001] The invention relates to automobile components, in particular to an automobile rear seat cushion and a processing and assembling method thereof. Background technique [0002] The structure of the automobile rear seat cushion of prior art has following two kinds: 1, the cushion core outsourcing seat skin of inserting steel wire in the PUR (polyurethane foam material). 2. PUR embedded steel wire + EPP (polypropylene foam material) is embedded with steel wire and outsourced with seat skin. The first solution is heavy, expensive, not environmentally friendly, and has a low level of safety performance. It is difficult to pass the crash test requirements in the C-NAP regulations. The overall seat is soft. The second option has improved the safety level, but it is not as soft and basically airtight as pure PU (polyurethane) overall, the ride comfort is poor, and the safety level is not particularly high. Moreover, the fixing method of the seat frame is to ...
