Abstract
An air bag module is provided for inflating an air bag cushion at dual rates in response to rapid deceleration of a motor vehicle. The air bag module includes an air bag housing for receiving an inflator. The air bag cushion is secured to a peripheral flange of the housing in a folded position. Upon actuation of the inflator, heated gas passes selectively from the inflator through a plurality of openings in the housing. A controller generates an ignition signal to the inflator in response to velocity responsive sensors. In response to the ignition signals, the inflator releases an appropriate predetermined volume of gas into the air bag cushion. The level of deployment or inflation of the air bag cushion is dependent on the actuation of a slide slidably arranged to selectively block the openings of the air bag housing to restrict gas flow to the air bag cushion. The housing further includes venting apertures to permit gas flow from the housing and thereby redirect the gas away from the air bag cushion.
