Abstract

A length adjustment mechanism for a strap having a row of teeth. The mechanism comprises a pinion for meshing with the row of teeth and a finger operable actuator pivotable in a first direction and a second direction. The mechanism also comprises a pivoting link coupled with the pinion, the pivoting link being pivotable about a first pivot axis to impart pivotal movement to the pinion. The mechanism further comprises a rotating element coupled with the finger operable actuator and being pivotable about a second pivot axis. The rotating element engages the pivoting link in a driving relationship such that movement of the finger operable actuator is communicated to the pinion via the rotating element and the pivoting link to displace the strap. When a force is applied to the pinion for tending to pivot the pivoting link, the pivoting link and the rotating element interlock for resisting pivotal movement of the pinion.
