Abstract
An improved device for controlling the rate at which gas is exhausted from an air bag cushion which is used in passenger vehicles. A novel gas vent is incorporated into the material from which the air bag is made, The vent comprises a dynamic vent that is impermeable to gas below a critical temperature and is permeable to gas above a critical temperature. The dynamic vent provides additional venting of gas during a high impact collision or when a larger than average occupant impacts onto the air bag cushion.
