Abstract
The invention relates to an airbag module for a motor vehicle, comprising a gas sack package comprising a gas sack, an additional moveable element configured and provided to influence a state variable of the airbag, and a gas-tight protective covering that defines an inner space of the gas sack package, wherein the gas sack and the moveable element are arranged in said inner space, and a separate movement generating device configured and provided to move the moveable element. According to the invention, the movement generating device is arranged outside the inner space of the airbag package.
Claims15
An airbag module for a motor vehicle, comprising:
- a gas sack package, comprising:
- a gas sack,
- a movable element configured and provided to influence a state variable of the gas sack, and
- a gas-tight protective covering that defines an inner space of the gas sack package, wherein the gas sack and the movable element are arranged in said inner space, and
- a movement generating device configured and provided to move the movable element, in order to influence the state variable,
- wherein the movement generating device is arranged separately outside the inner space of the gas sack package such that the movement generating device is at least separated by the protective covering from components of the airbag module arranged in the inner space of the gas sack package.

- a carrier of the airbag module for carrying the gas sack package, wherein the movement generating device is arranged on the carrier,
- wherein the movement generating device is arranged in a through-opening of the carrier so that a free end portion of the movement generating device, via which pressure for acting on the movable element is provided, protrudes along a first direction out of said through-opening,
- wherein the free end portion of the movement generating device faces the movable element along the first direction,
- wherein a region of the protective covering faces a front face of the movement generating device extending across the first direction, and
- wherein said region is destroyed, when the movement generating device provides said pressure.
