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.

[ What is claimed is:] [1.]1. Air bag system comprising an air bag, multi-stage gas generating devices for inflating the air bag to a primary stage wherein the air bag is partially inflated to a predetermined state, and to at least one subsequent stage wherein the air bag is further inflated, at least one electric switch, at least one mechanical device coupling said at least one electric switch to the air bag for causing said at least one electric switch to be switched, responsive to unhindered expansion of the air bag to said predetermined state of partial inflation, to trigger the gas generating device for the at least one subsequent stage to produce said further inflation of the air bag and wherein a voltage source is applied to the at least one electric switch, one side of which is connected to ground, and wherein when the air bag has inflated to the predetermined state of partial inflation, the connection to ground is broken.
