Tensioning apparatus
A belt (3) can be pulled out from a spring biased retractor reel (2) when a ratchet mechanism (16) is released. The belt (3) is entrained around a movable shoe (4) before being led to a fastening point. When fastened, the spring bias in the reel (2) takes up the slack. Operation of an actuator, such as by depression of a pedal (10), first causes the ratchet mechanism (16) to engage and then shifts the shoe (4) to stretch and tension the belt between the reel (2) and the fastening point. The pedal (10) is retainable in its fully depressed, belt-tensioning position.
