Airbag module with inflation control

摘要

An airbag module includes a housing having at least one aperture for releasing gas from an interior of the housing during inflation of an airbag. The airbag module also includes a member configured for movement between a first position in which the member impedes the flow of gas through the at least one aperture and a second position in which the member does not impede the flow of gas through the at least one aperture. A pyrotechnic device is attached to the member for directing a burst of gas toward a fixed surface to cause the member and the pyrotechnic device to move between the first position and the second position.
