Airbag module for vehicles, has locking member that prevents vent member from moving back to open position after vent member has moved to closed position

摘要

A reaction plate (40) has a vent opening (50) through which inflation fluid flows into an airbag (12). A vent member (58) is moved to a closed position to restrict flow of inflation fluid through the vent opening when an outer panel (18) of the airbag moves away from the reaction plate by more than a predetermined distance. A locking member (96) prevents the vent member from moving back to the open position.
