Abstract

The invention relates to a body part (1) for a motor vehicle, comprising a body (2) made of plastic and an anti-pinch system. The anti-pinch system comprises a capacitive sensor comprising at least a first wire (4) integrated in the thickness of the body by welding, the capacitive sensor being adapted to detect the presence of an object or a hand of a user in a peripheral area of the body.

Description

technical field [0001] The present invention relates to the field of the motor vehicle industry, and more particularly to body parts made of plastics intended to be mounted on motor vehicles. Background technique [0002] Many modern vehicles are equipped with body parts made of plastic, such as closures, such as tailgates or doors, which are equipped with motors for opening and closing functions. Such closures may be equipped with anti-pinch devices comprising capacitive sensors arranged at the periphery of the closure, at the side edges. [0003] Capacitive sensors allow short-range detection of changes in capacitance due to the presence of an object or the presence of an object in the sensor's detection field. [0004] In general, such sensors thus detect the presence of an object entering the detection field without contact by detecting a change in capacitance. The anti-pinch device then stops closing the tailgate before an obstacle becomes trapped between the closure ...
