Abstract:
1. An actuation device for pull-out element of a component having a corpus, wherein the pull-out element is moveable by a drive unit relative to the corpus, wherein the drive unit is activatable by control means and moveable into an open position, wherein the control means comprise a first sensor and a second sensor, wherein the first sensor is a front body sound sensor correlated with a front element of the pull-out element and the second sensor is a corpus body sound sensor that is arranged in or on the corpus at a spacing to the front body sound sensor, wherein the control means comprise an evaluation unit that carries out a signal comparison of body sound signals of the front body sound sensor and of body sound signals of the corpus body sound sensor with each other, wherein the drive unit is activatable as a function of a result of the signal comparison by the control means, wherein the corpus body sound sensor is arranged on a sidewall of the corpus body or on the drive unit and has a sensing orientation that is substantially transverse to a sensing orientation of the front body sound sensor and substantially parallel to a length extension of the front element.
