Abstract
A tensioning assembly for the stepwise tightening and releasing of a tensioning strap includes a frame (1), a tensioning lever (2), and a wind-up spindle (4) supporting ratchet wheels (3, 3'). A driving pawl (19) which is movably mounted on the tensioning lever (2) serves to rotate the wind-up spindle (4) when the strap is being tightened. Reverse rotation of the wind-up spindle (4) is prevented by a pair of locking pawls (5, 5') which are movably mounted on the frame (1). The lower or bearing end of the tensioning lever (2) has an unlatching cam (37) which permits the locking pawls (5, 5') to be alternatingly moved out of engagement with the teeth of the ratchet wheels (3, 3'), thus promoting safety by relieving the strap tension in stages. An isolating cam (40) at the bearing end of the tensioning lever (2) permits both locking pawls (5, 5') to be disengaged after the strap tension has been reduced.
