Abstract
The invention relates to an air bag system which has multi-stage gas generating devices, with a primary stage for the partial inflating of an air bag and at least one subsequent stage which can be electrically and/or electronically triggered only as a function of an unhindered expansion of the air bag because of the inflating by a preceding stage, at least one electric switch being provided which can be switched as a function of the undisturbed expansion of the air bag because of the inflating by the preceding stage and is connected for the electric and/or electronic triggering of the subsequent stage. The invention also relates to a triggering process for an air bag system having multi-stage gas generating devices, by a primary stage, an air bag being partially inflated and, only as a function of an undisturbed expansion of the air bag because of the inflating by a preceding stage, at least one subsequent stage being electrically and/or electronically triggered, as a function of the undisturbed expansion of the air bag because of the inflating by the preceding stage, at least one electric switch being operated, and, as the result, the subsequent stage being electrically and/or electronically triggered.
