Module for an occupant-protection device of a motor vehicle
View Patent ↗The invention relates to a module ( 1 ) for an occupant-protection device of a motor vehicle. Said module containing a functional element ( 2 ), which can be activated if the motor vehicle is involved in a collision and which comprises an electrically conductive material and a fixing device ( 3 ) mechanically fixing the functional element ( 2 ) to the bodywork of the motor vehicle. According to the invention, the functional element ( 2 ) is electrically insulated in relation to the bodywork of the motor vehicle. According to the invention, the functional element ( 2 ) is electrically insulated in relation to the bodywork of the motor vehicle. This guarantees that the functional element, which can be activated in a collision, cannot electrically interact with the bodywork of the motor vehicle, is particular in the form of a voltage surge. The invention permits the reliability of a module for an occupant-protection device of a motor vehicle to be increased and prevents potential malfunctions in a simple manner.
