Airbag device in a vehicle and method for activating an airbag device
First Claim
1. Air bag arrangement in a vehicle comprising:
- gas bag which can be inflated with gas, a sensor which triggers inflation of the gas bag so that, while inflating, the gas bag can be advanced into a vehicle interior, and first and further propellant charges providing at least two successively ignitable driving stages, ignition of the first propellant charge being triggered by said sensor and each further propellant charge being ignited when the gas bag moves beyond a respectively defined advancing position, wherein the gas bag itself, while advancing, controls triggering of an ignition device of a second propellant charge.

Abstract
The invention relates to an air bag arrangement in vehicle, having a gas bag which, as the result of a triggering by a sensor, can be inflated with gas by a gas generator and, during the inflating, can be advanced into an interior of the vehicle, the gas generator having at least two driving stages with propellant charges which can be ignited in a time-related succession and of which the first propellant charge is ignited by a triggering by a sensor and the second propellant charge being ignited facultatively when the gas bag moves beyond a defined advancing position. In addition, the invention relates to a triggering process for an air bag arrangement, wherein, as a function of the driving situation, a first stage of at least one gas generator or at least a first gas generator is triggered, the gas generated in this manner is guided into at least one gas bag for its partial filling, at least one possible hindering of the expansion of the gas bag is detected, and in the case of an unhindered expansion of the gas bag at least one additional stage of the gas generator or at least one additional gas generator is triggered for the further or complete filling of the gas bag.

25. Triggering process for an air bag arrangement comprising the steps of:
-
triggering a first stage of at least one gas generator or at least a first gas generator as a function of a driving situation, guiding gas generated in this manner into at least one gas bag for partial filling of the at least one gas bag, controlling, by the gas bag itself while it is advancing during filling, triggering of at least one additional stage of the gas generator or at least one additional gas generator for further or complete filling of the gas bag. - View Dependent Claims (26)
