DRIVE DEVICE AND METHOD FOR CONTROLLING THE DRIVE DEVICE FOR THE GENERATION OF AN ACTUATION MOVEMENT
First Claim
1. Drive device for the generation of an actuation movement, having at least one actuation element made from a memory shape alloy, having at least one resetting element which counteracts the actuation movement of the at least one actuation element, wherein the at least one actuation element is received between two connection elements that are arranged separately from each other and with spacing apart from each other and engages with or is fastened to each connection element, the connection elements are held at a distance by the at least one actuation element and the at least one resetting element, which are positioned between the connection elements, and, as a result of the opposing directions of action thereof, the connection elements are positioned in a defined starting position for controlling an actuation movement.
