Said unit having an energy-buffer (14, 19) into which energy can be fed and accumulated by moving the head, which accumulated energy supports the adjustment device of the foot. Said energy-buffer can be a spring (14), with or without a lostmotion-connection (15), which spring by means of a reversing gear (11, 12) acts on the foot lever (7) or by switching past its pivot point acts like a flip-flop.
