Zusammenfassung: | An air bag pressure control system for use in a vehicle is provided. The system comprises a housing, an inflatable cushion, and a dual stage inflator. The inflator generates a quantity of inflation gas to deploy the inflatable cushion from the housing. A vent opening is formed in the housing to selectively direct a portion of the inflation gas towards or away from the inflatable cushion. A sensing and diagnostic module detects an activation event level. A control algorithm tailors an inflation level of the inflatable cushion during deployment according to the activation event level. |
