A method for folding a driver airbag, comprising the steps of providing a driver airbag with an insertion opening for a gas generator positioned on a back side of the airbag opposite a front side of the airbag and deploying away therefrom towards a user after activation of the gas generator, folding the airbag in alternating directions around an imaginary center along first fold lines extending from the imaginary center and pressing together towards the center, at least one partial region of the airbag, and rolling or folding up the at least one partial region in a direction along the back side of the airbag.
An airbag module comprising a gas generator and an airbag that forms an insertion opening for the gas generator and the airbag deploying toward a user after activation of the gas generator, wherein the airbag is folded in alternating directions around an imaginary center along first fold lines extending from the imaginary center and pressed together towards the imaginary center, at least one partial region of the airbag is rolled up or folded up along second fold lines towards a back side of the airbag forming the insertion opening.
