Webbing length adjustor

A webbing length adjustor adapted to clamp webbing having a free end and a tension end when tension is applied to the tension end of the webbing, the adjustor comprising;

• a webbing guide,
• a clamp element pivotally mounted with respect to said webbing guide,
• a locking cam on said clamp element which in a locked position clamps said webbing between said locking cam and said webbing guide to prevent movement of said webbing through said adjustor when said tension is applied to the tension end,
• a release actuator to cause rotation of said clamp element to move said locking cam to a position where said webbing is released to allow it to move in either direction through said adjustor, and
• a projection on said clamp element that abuts against the webbing between the locking cam and the tension end thereof so that said webbing when tensioned exerts a force against said projection which urges or causes rotation of said clamp element in a direction that holds or moves said locking cam in or into said locked position.
