1. Device for the production of a haptic feedback from a keyless input unit of an input device, wherein the device has an elastic, essentially plate-shaped substrate, which at least comprises a first support location for fixing the substrate on a structure of the input device and at least a second support location for fixing the substrate on the input unit, and is formed to support the input unit movably with respect to the structure of the input device, wherein a piezoelectric element between the first and second support locations of the substrate is connected to it such that a unimorphous bending element results and with an electrical drive to the piezoelectric element one of the support locations is moved transverse to the plane of the plate-shaped substrate.
