Automobile back-row cushion and machining-assembling method thereof

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 parts, in particular to a rear seat cushion of an automobile and a processing and assembly method thereof. Background technique [0002] The prior art car rear seat cushion has the following two structures: 1. PUR (polyurethane foam material) has a seat cushion core embedded with a steel wire out of the seat skin. 2. PUR embedded steel wire + EPP (polypropylene foam material) embedded steel wire and outsourcing seat skin. The first option is that the 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 solution has improved the safety level, but it is not as soft as pure PU (polyurethane) and is basically airtight, and the ride comfort is poor, and the safety level is not particularly high. Moreover, the seat frame is fixed by interference assembly w...

AI Technical Summary

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
