Abstract
An air bag module for protection of a vehicle occupant includes an inflation control device. The module includes an air bag and an inflator for discharging inflator gas for inflating the air bag. The inflator has a first stage of inflation for discharging a predetermined first amount of inflator gas and has a second stage of inflation for discharging a predetermined second amount of inflator gas. A switch member is operatively connected to the inflator. The switch member is disposable between a first position in which the inflator discharges the first stage of gas and a second position in which the inflator discharges the second stage of gas. A tether has a first end operatively associated with the switch member and a second end operatively associated with the air bag. The first end of the tether changes the switch member from the first position to the second position when the tether is tensioned a predetermined amount during air bag inflation.
