Abstract

The mechanism (24) has a coupling unit (34) for rotationally coupling an input shaft (26) and an output shaft (28), where a back frame (32) is positioned between the input shaft and the output shaft. A locking unit (44) locks rotation of the input shaft on a front frame. Another locking unit (46) locks rotation of the output shaft on the rear frame. The locking units are designed to lock automatically the input shaft and the output shaft respectively in rotation, under the effect of displacement of the rear frame to a back extended position.
