Abstract

PROBLEM TO BE SOLVED: To positively rupture the stitching part of sheathing material for a seat back by letting a load transmitting member surely function when an air bag is inflated in this air bag device for side collision housing the air bag in the inside of the seat back. SOLUTION: An module case 35 housing an air bag 4, and a front and a rear pad 19 and 20 are disposed in the inside of a seat back 2, base ends are fixed by a clip 28 so as to allow the tip end of ground fabric 30f wound around the front face of the pad 19 to be bonded with the stitching part 25 of sheathing material 21 and 22, and the tip end of ground fabric 30f fabric at the rear side, which is fixed by the clip 28 at its base ends, and is wound around the rear surface of the pad 29 and the right side surface of the module case 35, is bonded with the stitching part 25 of the sheathing material 21 and 22. The hardness of a portion 29h, against which the stay cloth 30r at the rear side out of the pad 29 at the rear side abuts, is set up to be higher than that for the other portions, and when the air bag 4 is inflated so as to allow a lid 37 to be opened, the tension of the stay cloth 30r is surely transmitted to the stitching part 25 so as to enable the stitching part 25 to be thereby ruptured.

In order to achieve the above object, according to the first aspect of the present invention, a folded airbag is housed inside a seat back filled with a pad, and a pad and a folded airbag are stored. An end of the load transmitting member along the outer periphery of the bag is connected to a sewn portion of the covering material of the seat back, and the load for inflating the airbag is transmitted to the sewn portion via the load transmitting member. In a side collision airbag device in which the sewn portion is broken and the airbag is deployed in the vehicle cabin through the opening formed by the break, the hardness of a portion of the pad that comes into contact with the load transmitting member is made smaller than the hardness of a portion that does not come into contact with the pad. Is also set high.

According to the above construction, when the airbag is inflated inside the seatback due to the collision of the vehicle, tension is generated in the load transmitting member due to the pressure of the inflating airbag, and the seatback connected to the load transmitting member is tensioned. The opening at which the airbag deploys can be formed by breaking the sewn portion of the airbag.
When tension is generated in the load transmitting member, the pad is compressed by the load transmitting member. However, by setting the hardness of the portion of the pad in contact with the load transmitting member to be higher than the hardness of the non-contacting portion, the compressive force is reduced. , The tension of the load transmitting member is effectively transmitted to the sewn portion of the seat back, and the sewn portion can be reliably broken.

At this time, as shown in FIGS. 2 and 7,
The distal end of the rear webbing 30r with the base end fixed is
At the edge of the third coating material 22,
The rear webbing 30 is formed by the lid 37 rotating to the side of the vehicle body.
When r is pressed to generate tension, the edge of the third covering material 22 is pulled backward by the tip of the webbing 30r. Further, since the distal end of the front webbing 30f with the base end fixed is connected to the edge of the second covering material 21 at the sewn portion 25, tension is also applied to the front webbing 30f connected to the rear webbing 30r. Occurs, and the edge of the second coating material 21 is pulled forward by the tension.

However, as shown in FIG. 7, in the present embodiment, the portion of the pad 29 that contacts the rear webbing 30r is a hard portion 29h having a high hardness, so that the tension of the webbing 30r acts. Also, since the hard portion 29h retains its shape without being crushed, FIG.
As shown in (b), the tension of the webbing 30r can be effectively transmitted to the sewn portion 25, and the sewn portion 25 can be reliably broken.

In the embodiment, the hard portion 29h is provided only on the rear pad 29. However, the hard portion may be provided on the front pad 19 around which the front webbing 30f is wound. However, since the hardness of the pad 18 on the front side affects the feel of the occupant's back, it is desirable that the hardness of the hard part is slightly higher than the hardness of the soft part.

As described above, according to the first aspect of the present invention, when the airbag inflates inside the seat back due to the collision of the vehicle, tension is generated in the load transmitting member by the pressure of the inflating airbag. Then, the sewing portion of the seat back connected to the load transmitting member can be broken to form an opening through which the airbag deploys. The pad is compressed by the load transmitting member when tension is generated in the load transmitting member, but by setting the hardness of the portion of the pad in contact with the load transmitting member to be higher than the hardness of the non-contacting portion,
By preventing the pad from being crushed by the compressive force, the tension of the load transmitting member can be effectively transmitted to the sewn portion of the seat back, and the sewn portion can be reliably broken.
