なっている。In FIGS. 1 and 2, reference numeral 1 denotes an airbag unit. The airbag unit 1 is disposed on a side wall in a vehicle compartment, for example, on an inner panel 3a of a front door 3, and is used when a side collision of the vehicle occurs. In the event of an emergency, the bag body 2 operates based on the detection action of the collision detection means (not shown).
Is expanded and deployed in a flat shape substantially along the side of the cabin.

が遅くなるためである。 According to the structure of the embodiment described above, when the airbag unit 1 is activated and the bag body 2 is inflated in an emergency such as a side collision of the vehicle, the bag body 2 is initially inflated from both front and rear ends. The folding of the bag body 2 toward the center of the passenger compartment is restricted by the bellows-like folding of the bag body and the winding from the upper and lower directions, and as shown in FIG. Jo folding portion is first <br/> before, after starting to extend in two directions, the deployment of the folded portion
At the same time, the rolled part also begins to unfold. This
Unfolding unfolds ahead of roll-in
The reason is that the folded part is the cloth
The friction is small and the deployment speed is fast, but the entangled part is
The friction between the fabrics constituting the bag body is large, and the deployment speed
This is because it becomes slow.

きて、乗員Ｈの横方向移動を拘束することができる。As a result, the front and rear deployment between the side of the cabin of the bag body 2 and the side of the occupant H seated on the front seat 4 precedes, and the rear side of the bag body 2 is indicated by a chain line in FIG. Therefore, the bag body 2 can be reliably inflated and deployed between the side surface of the passenger compartment and the side of the occupant H as shown by the solid line in FIG. As a result, the lateral movement of the occupant H can be restrained.

きる。As described above, according to the present invention, when the bag main body is inflated, the central portion of the bag main body is prevented from expanding toward the passenger compartment at a stretch, so that the front and rear directions can be expanded. As the bag body can be inflated and deployed reliably between the side surface of the passenger compartment and the side of the occupant, the occupant can be more thoroughly protected in the event of a side collision or the like.
