Abstract
An occupant protection device for a motor vehicle has at least one inflatable airbag which, upon activation of at least one associated gas generator passes through, leaves an exit opening in the region in front of an occupant and enters the interior of the motor vehicle. The airbag has a multi-chambered design and has at least one inflatable thorax-protection gas chamber and a head-protection gas chamber, which is connected to the said thorax-protection gas chamber by gas-throughflow openings and, with the airbag inflated, lies above the thorax-protection gas chamber, the thorax-protection gas chamber is preceded by a smaller inflatable gas prechamber, which is in connection with the gas generator and can be inflated directly by the latter. The gas prechamber is connected to the thorax-protection gas chamber of gas-throughflow openings, so that the thorax-protection gas chamber can be inflated indirectly by the gas generator via the gas prechamber.
