AIRBAG DEVICE

摘要

An airbag device for stably controlling gas discharge and restraining an occupant in a vehicle. A first vent hole, for discharging gas from the airbag, is formed in a portion of the airbag, and one end of a tubular discharge restricting member is connected to the first vent hole. Once the airbag is inflated and deployed to a predetermined extent or more, the first vent hole is closed by the discharge restricting member. Prior to deployment, at least a portion of the airbag is folded in a bellows shape to form a folded portion. The connecting portion between the discharge restricting member and the first vent hole is positioned in a trough portion of the folded portion. The other end of the discharge restricting member is stored so as to face the outer side and not to protrude beyond an outer edge of the folded portion.

主权项

1. An airbag device for restraining an occupant in the cabin of an automotive vehicle, the airbag device comprising:
an airbag coupled to an inflator, the inflator configured to cause inflation and deployment of the airbag, at least one first vent hole defined in the airbag to exhaust inflation gas from inside the airbag; an exhaust control portion having a base and a distal end, the base of the exhaust control portion being connected about the first vent hole and the exhaust control portion extending outwardly from the airbag; in a non-deployed configuration, the airbag having folded portions defining troughs and peaks, the troughs being located inwardly of the non-deployed configuration and peaks defining an outer side of the non-deployed configuration, the base of the exhaust control portion being located at one of the troughs of the non-deployed configuration and the distal end of the exhaust control portion being located toward the outer side of the non-deployed configuration.
