Abstract

A side collision airbag device includes an airbag to inflate and extend between a side wall portion of a vehicle and an occupant seated on a seat disposed in the vehicle. An inflator is connected to the airbag to spout a gas for inflating and extending the airbag from one side thereof in its longitudinal direction. A restricting member is attached for restricting a movement of the inflator toward the other side thereof in its longitudinal direction when the inflator is activated.

Claims

1. A side collision airbag device, comprising:

an airbag to inflate and extend between a side wall portion of a vehicle and an occupant seated on a seat disposed in the vehicle;

an inflator connected to the airbag to spout a gas for inflating and extending the airbag from one side thereof in a longitudinal direction thereof; and

a restricting member for restricting a movement of the inflator toward the other side thereof in the longitudinal direction when the inflator is activated.

2. A side collision airbag device as recited in claim 1, further comprising a supporting member for supporting the inflator, the supporting member being provided as a separate member from the restricting member.

3. A side collision airbag device as recited in claim 2, wherein the restricting member comprises a securing portion for covering at least a part of an end portion on the other side of the inflator in the longitudinal direction thereof.

4. A side collision airbag device as recited in claim 3, further comprising a fixing member for fixing the supporting member to the vehicle, wherein the restricting member further comprises an elongated portion elongated along the longitudinal direction of the inflator and covering the supporting member, the elongated porting being secured by the fixing member.

5. A side collision airbag device as recited in claim 4, wherein the restricting member further comprises a projecting portion so as to project toward a side opposite to a side where the inflator is disposed.

6. A side collision airbag device as recited in claim 5, further comprising a casing for accommodating a folded side of the airbag, the casing having a hole for confirming the projecting portion formed at a position corresponding to the projecting portion.

7. A side collision airbag device as recited in claim 6, the airbag is folded and housed in the casing in an accordion shape.
