ABSTRACT:
A device for transmitting linear motion for adjustment of a wing element (4) is provided with one input part (23) and one output part (26) wherein between the input part (23) and the output part (26) an uncoupling mechanism is provided which, above a preset force (release force) makes relative motion between the input part and the output part possible. One or more prestressed springs (42), which can absorb energy during relative motion, upon unloading, restores the input and output parts to an initial position. A translation mechanism converts the relative motion between the input part (23) and the output part (26). The converted motion acts upon the spring (42) whereby a force-path characteristic line of the device, corresponding to the translation mechanism, can be obtained. The translation mechanism consists of a crankshaft (52) with cam discs (50A, 50B) driven by a connecting rod (46) which act upon a piston (48) longitudinally movable within the housing (30) and prestressed by springs (42).
