Device for Actuating an Electrical or Mechanical Closure Mechanism on a Vehicle Door and/or Shutter
First Claim
1. Arrangement for actuating an electrical or electromechanical closing device (10) on a door (12) and/or a hatch of a vehicle, with a handle (20), which is used to open and/or to close a lock (30) provided on the door (12) and/or hatch, with at least two sensors, which, upon approach or contact, transmit separate signals, the signals nevertheless being evaluated (42) jointly, with the result that the lock (30) is switched between an unlocked position and a locked position, where, in the unlocked position, the actuation of the handle (20) is functionally effective for the lock (30) but is not functionally effective in the locked position, wherein a capacitive main sensor (40) and an auxiliary sensor (50) equipped with a piezoelectric element (51) are arranged one on top of the other at a common actuating point;
- in that the common actuating point consists of an elastically resilient wall (28), which, when contacted, exerts pressure on the piezoelectric element (51); and
in that a successful evaluation (43) of the signals coming from the main and auxiliary sensors (40, 50) switches the clock (30) to its locking position.

Abstract
The invention concerns a device for actuating an electrical or mechanical closure mechanism on a vehicle door and/or shutter, involving the use of a sensor (40) which responds to nearness or touch. For the device to identify unequivocally whether the sensor control (40) is actually performed by a human hand or inadvertently by an object, an auxiliary sensor (50) which, in the form of a detection element has a piezoelectric element (51), is arranged at the main sensor (40) contact zone. At least the auxiliary sensor (50) is covered with a flexible wall (28) which, upon contact, exerts a pressure on the piezoelectric element (51) and forms a common actuating location (28). When said actuating zone is contacted, the main sensor and the auxiliary sensor (40, 50) emit separate signals which however are evaluated in the same way (42). When the result of the evaluation is positive, an output signal is emitted, said signal shifting the lock to its locking position. The actuating of the handle (20) is then ineffective.
