ABSTRACT:
A valve for controlling a port in an air bag comprises a circular valve disk secured over the port. The disk has a circular mounting ring. Flexible valve elements extend radially inwardly from the ring. Each valve element is in the form of a wedge-shaped leaf with opposite side edges tapering radially inwardly to a point at the center of the ring. The valve is closed when the side edges of adjacent leaves are in contact. When the air bag deploys, the pressure of air in the bag flexes the leaves outwardly to open the valve.
