Abstract: A knee brace having an upper part securable about a user's thigh and a lower part securable about the user's lower leg is provided. The upper and lower parts are secured together adjacent the user's knee by a hinge. The knee brace is characterised in that a flexible tensioning element extends between the upper part and the lower part over a lobe which is secured to the upper part adjacent the hinge such that pivoting of the upper and lower parts about the hinge causes the flexible element to engage the lobe about its periphery to cause tension in the flexible element and wherein the lobe is shaped to cause the tension to dynamically increase as the upper part is pivoted relative to the lower part.

Abstract: A system for supporting a trailer mover in a fixed spatial relationship to the wheels of a trailer is provided. The system has embodiments handling both independent and non-independent suspension; movers mounted either before or aft the wheels; and, movers mounted on either left hand or right hand wheels. The system attaches to the sprung portion of the trailer suspension to provide the fixed spatial relationship. Adjustable components provide longitudinal and lateral adjustment of the position of the trailer mover to cater for different proximal wheel and suspension geometries.
