The spindle is supported for rotation in belt retraction and withdrawal directions and is biased to rotate in the belt retraction direction. The apparatus comprises a ratchet wheel connected to the spindle for rotation with the spindle. A plurality of ratchet teeth extend from the ratchet wheel. A member is movable from a first position in which the member is spaced from the ratchet wheel to a second position in which the member engages one of the plurality of ratchet teeth on the ratchet wheel to block rotation of the ratchet wheel and the spindle in the belt retraction direction. A cam disk separate from the ratchet wheel prevents movement of the member to its second position during rotation of the spindle in the belt retraction at a speed above a predetermined speed. | |
