Abstract
A triggering device for a horn system of a motor vehicle is integrated in a steering wheel (2) of the motor vehicle. In order to prevent a relative movement of components associated with the steering wheel in relation to each other, but still enable a secure and reliable actuation of the triggering device of the horn system while at the same time allowing an optically compact and appealing design of the steering wheel (2), the invention proposes for the triggering device to comprise a first triggering unit (7), with which a parameter inherent in intended activation of the horn is detected. When such a parameter is detected, a first triggering signal can be emitted. The invention comprises a second triggering unit (11), with which a further parameter inherent in an intended activation of the horn is detected and a second triggering signal can be emitted. By means of the triggering device (7, 11), the horn system of the motor vehicle can be put into operation when the first triggering signal is emitted by the first triggering unit (7) and the second triggering signal is emitted by the second triggering unit (11).
