Patent ID: 8157291

Claim:
A safety arrangement for a motor vehicle comprising: an airbag operable to be inflated with different volumes in a direction of an interior of the vehicle by a gas generator in response to an activation signal; a crash sensor system which detects a vehicle impact and emits the activation signal, the crash sensor system including a pre-crash sensor system and an in-crash sensor system, the pre-crash sensor system operable for detecting an impending collision before an actual impact and for this circumstance emitting a pre-crash activation signal as the activation signal, and the in-crash sensor system operable for detecting an actual impact and for this circumstance emits an in-crash activation signal if the pre-crash sensor system has previously not detected the impending collision and has not emitted a pre-crash activation signal; a first vent integrated in a module housing and able to be activated for controlling the gas mass flow for filling the airbag in the pre-crash mode with a large airbag volume or in the in-crash mode with a smaller airbag volume; and a second vent integrated in the airbag and able to be triggered pyrotechnically; wherein an inflation process for the larger airbag volume is activated by the pre-crash activation signal in a pre-crash mode, and the inflation process for the relatively smaller airbag volume is activated by the in-crash activation signal in an in-crash mode.
