Abstract

PURPOSE:To downsize a housing shape by sewing the edge parts of plural number of tethers to regulate a developing distance in the vehicular width direction on positions distant from fold positions in the case of folding up a bag body in an air bag capable of protecting a passenger while developing between the passenger and the side wall in a vehicle room. CONSTITUTION:An air bag 11 to be formed into a bag shape is arranged in a side door and so on by folding up door side ground fabric 13 and passenger side ground fabric 14 alternately and respectively inside along ridge folding lines (a) abd bottom folding lines (b). Here, plural number of tethers 15-18 are provided so as to regulate a developing distance in the vehicular width direction by connecting the inside surface of the passenger side ground fabric part 14 and the inside surface of the door side ground fabric part 13 with each other. These tethers 15-18 are installed in positions distant from fold positions so as to be put under an approximately horizontal condition when the air bag 11 is expanded. Furthermore, after these one edges are sewed on the door side ground fabric part 13 and the passenger side ground fabric part 14 by halving respectively, the other edge sides are tied together. Thereby, the air bag can be folded up compactly, and installation work of the tethers 15-18 becomes also easy.

Description of the Related Art An airbag that is deployed to protect an occupant during a frontal collision or a side collision is inflated by an inert gas generated by an inflator which is a part of an airbag device. The gas generant in the inflator is ignited by a signal output when a collision sensor arranged at a predetermined portion detects a collision, and a large amount of instantaneously generated gas fills the airbag rapidly and instantaneously. It inflates and expands between the driver and the steering wheel, between the passenger and the dashboard, or between each occupant and the side wall of the passenger compartment such as the inside of the side door to protect the occupant from a secondary collision. Protect.

うに規制する必要がある。For example, as disclosed in Japanese Patent Application Laid-Open No. 2-249740, in the case of a side airbag device which protects an occupant from an impact load applied to a side portion of a vehicle body, the airbag is provided between the occupant and a side wall of the passenger compartment. It is necessary to quickly deploy in the space between them, and at that time, the airbag needs to be deployed not only in the direction of the occupant but also in the upper direction. Therefore, in the case of this side airbag device, the thickness of the airbag in the vehicle body width direction does not become thicker than a certain value when inflated, for example, an occupant side base cloth and a door side base cloth of the airbag, Connection support member (tether etc.) at multiple points
Therefore, it is necessary to regulate so that the expanded shape of the airbag becomes a predetermined shape.

ないようにしている。5 to 7 are shown in US Pat. No. 4,969.
An example of a conventional side airbag device described in the specification of 6388 is shown. The airbag 1 of this device is shown.
Is stored inside a side door or the like on the side of the vehicle in a folded state. When the sensor detects a collision during a side collision of the vehicle, the inflator 2 is ignited, and a large amount of gas is generated to generate an airbag. 1 is inflated and deployed in a limited space between the occupant and the inner surface of the side door to protect the occupant from a secondary collision. Therefore, in this conventional side airbag device, the airbag 1 must be deployed not only in the direction of the occupant but also in the upward direction in a narrow space, and therefore, the inflation amount of the airbag 1 in the vehicle body width direction. That is, in order to regulate the thickness of the airbag 1, the door side base cloth 3 and the passenger side base cloth 4 of the airbag 1 are
The three tethers 5 prevent the vehicle from expanding too much in the vehicle width direction.

Since three wide cloth-shaped tethers 5 are radially attached to define the expanded shape of each, when the airbag 1 is folded, each tether 5 and these tethers 5 and the door-side base cloth 3 are folded. And the occupant-side base cloth 4 overlap with each other, and even if the sewing is performed without using the reinforcing cloth, the folds are thick and bulky, so that the storage space of the airbag 1 is large. There was a problem that became large.

The airbag 11 of the side airbag device has a door side base cloth 13 and an occupant side base cloth 14 which are opposed to each other as shown in FIG. Along the mountain fold line a and the valley fold line b shown in FIG. 1, the tethers 15 to 18 provided inside are sequentially bent from the outer side to the inner side.
2 is folded in the state shown in FIG. 2 without being folded in between and folded in the state shown in FIG. 2, covered with a cover as needed, and compactly housed in a side door or the like. At this time, each tether 15,
Reinforcing cloths 19, 20, and 34 provided on the sewing parts of
However, since it is formed in such a size that it can be accommodated between each mountain fold line a and each valley fold line b, each fold line does not become thick, and therefore it can be folded compactly. Further, when gas flows in at the time of collision, the airbag 11 linearly inflates upward, and the six tethers 15 to 18 separate the door-side base cloth 13 and the passenger-side base cloth 14 from each other by a predetermined distance. Since it is held at, the final expanded shape can be instantaneously expanded.
