CN203410338U - Automobile seat backrest foamed structure for airbag - Google Patents

Abstract

The utility model provides an automobile seat backrest foamed structure for an airbag. The automobile seat backrest foamed structure comprises a foamed body, wherein an airbag space used for arrangement of the airbag is formed in the foamed body; a groove is formed on the foamed body and is communicated with the airbag space; a non-woven fabric which is integrally foamed with the foamed body is formed on the foamed body beside the groove. The backrest foamed body is provided with the groove as an airbag expanding channel, and the groove structurally forms a weakening line of the airbag on the backrest foamed body to reduce the expanding resistance of the foaming to the airbag, in this way, the airbag can be successfully expanded under a good guarantee; the non-woven fabric and the foamed body are integrated, so that the non-woven fabric fixedly connects the foaming of the area, so as to improve the tearing strength of the foaming of the area, in this way, when the airbag explodes instantly and rushes out the backrest, the foaming can be not torn with the enough strength, and therefore, the problem of too large and too many missiles when the airbag explodes is reduced.

Description

A kind of motor vehicle seat back foaming structure for safety air bag

Technical field

The utility model relates to a kind of motor vehicle seat back foaming structure for safety air bag.

Background technology

Motor vehicle seat back safety air bag foaming body is provided with safety air bag position, thereby safety air bag when bumping is ejected, protection human-body safety.But because the line of weakness of the foam place design in air bag path does not have open-mindedly, the comparison of resistance while causing air bag to be gone out is large, produces a lot of foam splashes, and human body has been produced to very major injury.

Summary of the invention

In order to overcome the above-mentioned deficiency of the existing motor vehicle seat back foaming structure for safety air bag, the utility model provides a kind of safer motor vehicle seat back foaming structure for safety air bag.

The technical scheme in the invention for solving the technical problem is: a kind of motor vehicle seat back foaming structure for safety air bag, comprise foaming body, in described foaming body, have for laying the air bag space of safety air bag, described foaming body is provided with a grooving, and described grooving communicates with described air bag space;

The other foaming body of described grooving is provided with the nonwoven fabrics of foaming together with described foaming body.

Further, on the side of described grooving, post flannelette.

The beneficial effects of the utility model are: backrest foaming is provided with grooving as airbag deployment passage, this grooving has structurally formed the line of weakness of air bag in backrest foaming, thereby weakened the mounted resistance of foaming to air bag, and then can guarantee well that air bag can launch smoothly;

Nonwoven fabrics and foaming body shape are in aggregates, thereby nonwoven fabrics bonds together the foaming in this region firmly, and then improved the peel strength of this region foaming, like this when air bag is when moment, backrest was gone out in explosion, foaming just has enough intensity not to be torn to guarantee self, thereby while reaching the explosion of minimizing air bag, flies out the too large too many problem of thing.

Accompanying drawing explanation

Fig. 1 is cross sectional drawing of the present utility model.

Fig. 2 is the partial enlarged drawing of A part in Fig. 1.

The specific embodiment

Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.

A motor vehicle seat back foaming structure for safety air bag, comprises foaming body 1, has for laying the air bag space of safety air bag in described foaming body 1, and described foaming body is provided with a grooving 2, and described grooving 2 communicates with described air bag space; Described grooving 2 other foaming bodies are provided with the nonwoven fabrics 3 of foaming together with described foaming body.

Backrest foaming of the present utility model is provided with grooving 2 as airbag deployment passage, this grooving 2 has structurally formed the line of weakness of air bag in backrest foaming, thereby weakened the mounted resistance of foaming to air bag, and then can guarantee well that air bag can launch smoothly; Nonwoven fabrics 3 is in aggregates with foaming body shape, thereby nonwoven fabrics 3 bonds together the foaming in this region firmly, and then improved the peel strength of this region foaming, like this when air bag is when moment, backrest was gone out in explosion, foaming just has enough intensity not to be torn to guarantee self, thereby while reaching the explosion of minimizing air bag, flies out the too large too many problem of thing.

In the present embodiment, on the side of described grooving 2, post flannelette, the resistance in the time of air bag can further be reduced going out.

Claims (2)

1. the motor vehicle seat back foaming structure for safety air bag, comprise foaming body, in described foaming body, have for laying the air bag space of safety air bag, it is characterized in that: described foaming body is provided with a grooving, described grooving communicates with described air bag space;

The other foaming body of described grooving is provided with the nonwoven fabrics of foaming together with described foaming body.

2. the motor vehicle seat back foaming structure for safety air bag as claimed in claim 1, is characterized in that: on the side of described grooving, post flannelette.
