Abstract

PROBLEM TO BE SOLVED: To surely and quickly cut out the rupture part of a trim cover by the swelling pressure of an air bag even if the output pressure of an inflator is set low by letting the swelling pressure of the air bag be instantly concentrated to the rupture part of the trim cover with help of stay cloth. SOLUTION: Power fabric 7 and 8 less in elongation is applied to the swelling and expansion area of an air bag in a place covering both the forward surface side 2a and side surface side 2b of a trim cover 2, the end peripheries of power fabric pieces are sewn together so as to be formed into the seam of the rupture part 3 of the trim cover 2. Meanwhile, the other end periphery of the forward surface side is hung so as to be stretched together with the seat surface hanging part 2e of the trim cover 2, and the other end periphery of the side surface side 2b is also fixedly attached in series to the seat surface hanging part 2e from the rearback side of a seat back frame 4 so as to be stretched and disposed over to the inner side of the trim cover 2 as the stay cloth 7 and 8 surrounding an air bag device 1.

2. Description of the Related Art Conventionally, in a vehicle seat provided with an air bag device, a general portion of a trim cover is sewn from a sewing thread having a generally used strength, and a front side of a trim cover enclosing an equipment side of the air bag device. The end between the side and the side is sewn from a sewing thread having a relatively low strength, and a seam formed by the sewing thread having the low strength is formed with a break portion cut by the inflation pressure of the airbag by the output of the inflator ( JP-A-8-2168
No. 20).

[0003] However, even if the broken portion of the trim cover is a thread that can be easily cut by the inflation pressure of the airbag, it must be sewn with a sewing thread that is strong enough to withstand normal usability. In addition, since the trim cover is stretched at least in terms of material as the air bag is inflated and deployed, the stress caused by the expansion of the air bag cannot be instantaneously concentrated on the broken portion of the trim cover. In particular, if the output of the inflator is set low so that the airbag is soft and inflated and deployed in a soft manner, it is difficult to effectively incise the broken portion of the trim cover.

[0004] Focusing on concentrating the inflation pressure of the airbag at the seam that is the break portion of the trim cover, and by sewing one end together with the seam that is the break portion of the trim cover, the force of the material with little elongation is obtained. Vehicle seats in which a cloth is stretched inside a trim cover have been proposed (JP-A-9-71204, JP-A-9-71205, JP-A-9-123860).

[0005] However, the webbing is provided only on one side of the side surface of the trim cover with a seam therebetween serving as a break portion of the trim cover. In this case, it is not possible to prevent the side on which the webbing is not provided from being stretched by receiving the inflation pressure of the airbag, across the seam that becomes the break portion of the trim cover.

[0006] Therefore, it cannot be said that the stress caused by the inflation of the airbag is instantaneously concentrated on the seam which becomes the break portion of the trim cover, and it is still not enough. In addition, since the side of the trim cover on which the webbing is not provided extends, the airbag inflates to the side where the trim cover extends, so that the inflation balance or deployment direction of the airbag cannot be stably determined.

[0007] In addition, there has been proposed an apparatus in which one end is sewn together with a front end of the trim cover so that the webbing is provided on one side of the trim cover with a seam serving as a break portion of the trim cover (Japanese Patent Application Laid-Open No. 9-39711). No., JP-A-9-7686
No. 8). However, even in this case, since the webbing is provided only on one side with the seam serving as a break portion of the trim cover separated, the side of the trim cover where the webbing is not provided expands by receiving the inflation pressure of the airbag. Can not be suppressed.

The trim cover 2 can be sewn in a predetermined bag shape by sewing a thread having a number of about 8 which can withstand normal usability as upper and lower sewing threads and sewing the entire sewing machine. In the general section, a thread having a count of about 8 is sewn as upper and lower sewing threads, and a seam 2c serving as a break portion 3 of the trim cover 2 is made of a thread having a count of about 8 and a thread having a count of about 20. By sewing as a sewing thread, it is possible to sew easily while maintaining strength enough to withstand normal usability. This break portion 3 cuts the sewing thread of the seam 2c by the stress due to the inflation of the airbag, or cuts the seam of the seam 2c.
It can be formed to be incisable by allowing the seam allowance c to be unraveled with a sewing thread.

In the vehicle seat configured as described above, when an impact sensor provided on the vehicle body is operated and an output signal is transmitted from the impact sensor to the inflator, the airbag receives the output pressure of the inflator and inflates. expand. Along with this, the webbings 7, 8 are located in the inflated and deployed region of the airbag, and are pressed and pulled from the inside by the inflated pressure of the airbag. At this time, the webbings 7 and 8 receive the inflation pressure of the airbag, but they do not expand, so that the webbings 7 and 8 work to pull each other. Can be concentrated on the seam 2c.

In addition, since the webbings 7 and 8 each have a substantially trapezoidal area, the inflation pressure of the airbag is received over a wide area, and the short side of the seam 2c that becomes the broken portion 3 is sewn together. The stress caused by the inflation of the airbag is instantaneously concentrated on the local area.

For this reason, the seam 2c to be the break portion 3 is rapidly pulled by the power cloths 7 and 8 at the local area where the short sides of the power cloths 7 and 8 are sewn together, and the cut is quickly performed by the airbag. Since the seam 2c continuously extends in the length direction of the seam 2c by the inflation pressure, even when the output of the inflator is set low, the seam 2c required for inflation and deployment of the airbag can be quickly and reliably cut.

Although the above-described embodiment has been described based on a preferred trapezoidal cloth having a substantially trapezoidal area as the webbings 7 and 8, other webbings may be used as webbings 7 and 8 as shown in FIG. 5 and 6, and a combination of those having an area corresponding to substantially the entire front side 2a and substantially the entire side surface 2b covering the bank of the back pad 5, as shown in FIG. The same effect can be exerted by combining any one of a substantially trapezoidal shape, a band shape, and a substantially entire surface with the front side 2a and the side 2b as shown in FIG.

In addition to receiving the inflation pressure of the airbag with the large-area, substantially trapezoidal webbing, the short side of each webbing is instantaneously concentrated at the local portion of the seam where the trim cover is broken. be able to. For this reason,
The seam is rapidly pulled out from the local area where the short side of the webbing is sewn together with the webbing and cut out quickly, and the cutout extends continuously in the lengthwise direction of the seam by the inflation pressure of the airbag. Even when the output of the trim cover is set to be low, the stitches which become the break portions of the trim cover can be quickly and reliably cut.
