Spring motor for a reefing means of a sail as well as a vehicle equipped with such a spring motor reefing device

摘要

The present invention relates to a for a reefing device (1) certain spring motor (2) for winding up of a sail (5), wherein the spring motor (2) by means of a during the unwinding on the sail (5) acting tensile force is tensioned against its restoring force. The spring motor (2) has a plurality of in different parallel planes arranged plane spring elements (3, 4) which, by means of a shaft (16) are linked in a series circuit, wherein a first spring element (3) with the sail (5) and a second spring element (4) with a receptacle (10) is connected to the sailing vessel.
