Abstract: An approach detection device for motor vehicles includes a sensor carrier and a sensor electronic system disposed in a receiving space therein. The device includes a capacitive approach sensor coupled to an evaluation circuit which has a capacitive surface for detecting approaches. The device is mounted via a carrier frame, including a fastening section, to a vehicle body part and includes a detection opening. The sensor carrier is fastened to the carrier frame such that the active capacitive surface of the sensor is oriented toward the detection opening. A receiving space is defined by the detection opening and the sensor carrier and is formed in the region of the detection opening. A sealing element is disposed in the receiving space on the sensor carrier.

Abstract: A motor-vehicle door handle includes at least one electronics subassembly and a first sensor electrode for a first capacitive sensor for triggering an unlocking operation when an approach to a grasping area is sensed. The sensor electrode is connected to the electronics subassembly. In known motor-vehicle door handles, the sensor electrode is arranged within the electronics module a) over a large surface area and b) always adjacent to the grasping area. For the instant motor-vehicle door handle there is improved flexibility in respect of position and configuration of the electronics module. This is achieved by the first sensor electrode being, in part, led out of the electronics module, that part of the sensor electrode which is led out having a portion which is arranged adjacent to the grasping area in the motor-vehicle door handle such that an approach to the grasping area can be sensed.
