Abstract
An airbag device includes an airbag module and at least one airbag cover which is connected to a piston via pulling devices. The piston can be subjected to pyrotechnical action in order to produce a linear movement of the piston. When the piston is caused to move, the airbag cover moves from a closed position, in which the airbag cover blocks an exit path of the airbag out of the airbag module, into an open position, in which the airbag cover clears the exit path of the airbag out of the airbag module. The piston is forcibly guided to perform a helical movement so that the piston, when caused to move, performs a rotational movement during its linear movement, thus winding up the pulling devices. A method for operating an airbag device is also provided.
