Patent ID: 6913284

Claim:
An airbag system for a vehicle having sensors that detect an accident-specific variable and a person-specific variable, the system comprising: an airbag; a deployment arrangement adapted to fill the airbag with gas when the deployment arrangement interprets an event as an impact against an obstacle, the deployment arrangement including: independently deployable first and second chambers, the first chamber being capable of filling the airbag with a larger quantity of gas than the second chamber, wherein the deployment arrangement is configured to determine whether to deploy the first or second chamber first on the basis of an evaluation of the accident-specific variable and the person-specific variable, wherein the sensors include sensors for detecting an actual vehicle speed and a relative vehicle speed, and wherein the deployment arrangement is configured to determine whether to deploy the first or second chamber first on the basis of an evaluation of an crash angle and a crash severity, each of the crash angle and crash severity being determined as a function of vehicle type, the actual vehicle speed and the relative vehicle speed.
