Abstract
A steering device is configured for a vehicle, which includes a steering column, a steering-wheel hub and a steering wheel, the steering-wheel hub including an openable cover, behind which an airbag module containing a gas generator and an airbag is disposed. In the activated state of the airbag module, the cover unblocking an airbag outlet, through which the airbag can be inflated in front of the steering wheel. The cover is coupled to at least one pulling device, which can be operated by a pyrotechnic actuator in the form of a cylinder-piston unit, the gas generator forming the piston, which is supported so as to be moveable from a neutral position into a working position, in a cylinder region of the steering-wheel hub and/or of the steering column, which acts as a cylinder. The at least one pulling device is indirectly and/or directly connected to the gas generator so that, in response to the gas generator being displaced in the cylinder region, a tensile force can be applied to the at least one pulling device, so that the pulling device transfers the cover from its covering position into its open position, in order to open the airbag outlet.
