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 not actuated.
