ABSTRACT:
Power-operated closing devices, particularly electrically operated windows and sunroofs of motor vehicles, have two electrical conductors being spaced apart from each other for disengaging a switching process of a drive unit when brought into contact. For the purposes of simple manufacture and reliable contact-making, a trapping protector is provided, which includes a flexible hollow profile made of an elastomer or plastic material having a flat base area and a mounted arched profile area enclosing a hollow chamber. The base area and a zenith area of the arched profile area include conductive material and are separated from each other by insulating profile areas.
