Abstract
An airbag, in particular a front airbag, includes an outer wall having a front wall and a rear wall (18, 24) and a tether (16) as well as an electrically actuatable activation unit (26) for releasing the tether (16). The tether (16) includes plural tether portions (30, 32) connected to each other via a first tear seam (36). A tension means (40) is coupled to the tether (16) so that it destroys the first tear seam (36) when the activation unit (26) is actuated.
Claims18
An airbag system comprising:
- an airbag comprising a front wall and a rear wall, the airbag being configured to be inflated to a large inflated volume or a small inflated volume;
- a tear seam that controls whether the airbag is inflated to the large inflated volume or the small inflated volume;
- a tether provided inside the airbag, the tether comprising plural tether portions including a tension portion;
- an electrically actuatable activation unit connected to the tension portion of the tether and being configured to release the tension portion when actuated,
- wherein the airbag, tear seam, tether, and actuation unit are configured so that the actuation unit when actuated releases the tension portion, which causes the tear seam to be released so that airbag inflates to the large inflated volume, and so that the actuation unit when not actuated maintains its connection to the tension portion, which causes the tear seam to be maintained so that the airbag inflates to the small inflated volume.
