Abstract

Clamping member for a strap of the kind adapted to be located between a strap storage location and a strap utilization location, comprises a reaction member pivotally mounted on a base member for angular movement about a reaction member pivot axis, a guide member mounted for movement relative to the base member, and retention member for retaining the guide member and the reaction member in respective rest positions in which the strap is freely movable between the guide member and reaction member until the tension applied to the strap exceeds a predetermined level. Coupling member interconnects the reaction member and the guide member so that, when the tension in the belt exceeds the predetermined level, movement of the guide member causes corresponding movement of the reaction member, thereby wrapping the strap round both the reaction member and the guide member so that one layer of the strap is clamped against the reaction member by another layer of the strap. The reaction member is pivotally mounted on the base member by a first support link and the guide member is slidably mounted on guide member secured to the base member for movement in a direction having a component perpendicular to the reaction member pivot axis.
