Abstract
A side airbag device including an airbag (2); an inflator (3); and an inner tube (4) formed of a fabric and covering discharge holes (3a) of the inflator (3). The inner tube (4) protrudes toward a center of the airbag (2) in a deployed state and a first end (4b) is closed in the direction of gas discharge, and second ends (4c) that are in a vehicle height direction of the airbag (2) in the deployed state are open. The inner tube (4) is folded back at a folded-back portion (4d) inside the airbag (2) when the airbag (2) is folded in a case where the side airbag device is installed in a vehicle seat back.
Claims11
A side impact airbag device for installation in a seat back of a vehicle seat and adapted to deploy in response to an output signal from a sensor in the event of a side impact comprising:
- an airbag;
- an inflator provided in the airbag so as to supply inflation gas to the airbag in a folded state, thereby deploying the airbag to a deployed state;
- and
- an inner tube formed of a fabric and provided to cover discharge holes of the inflator in order to change a direction of a flow of the gas discharged from the inflator, wherein
- the inner tube is structured such that the inner tube protrudes toward a center of the airbag in the deployed state and having a first end that is in a directionT in which the gas is discharged from the inflator, is closed, and second ends that are in a vehicle height direction of the airbag in the deployed state and intersecting the discharge direction of the gas, which is discharged from the discharge holes of the inflator, are open, and
- the inner tube is folded back at a folded-back portion inside the airbag when the airbag in the folded state, and is unfolded when the airbag is in the deployed state.
