Abstract

An airbag unit and method for folding up a driver's airbag, which has an insertion opening for a gas generator and, after activation of the gas generator, is unfolded away therefrom in the direction of a user. The airbag is folded around an imaginary center in alternating directions along first folding lines running around the imaginary center and is compressed in the direction of the center. At least one partial region of the airbag is rolled up or folded over onto the side towards the insertion opening.
