Abstract
The invention relates to an airbag module that is integrated into a steering wheel and that can be moved relative to the steering wheel in order to actuate a horn. The airbag module comprises a horn switch provided on the module which, when the module is moved, is transferred into a switching position that causes the horn to be activated. A hollow profile made of elastomer is provided which is equipped with the horn switch and lies against the module. The invention further relates to a vehicle steering wheel equipped with such an airbag module.
