Ski binding heel assembly having radial release

Abstract From the Canadian patent

A ski binding heel assembly for releasably securing the heel of a ski boot on a ski incorporates structure providing or "radial release" of the ski boot, i.e. release in response to displacement forces applied in a plane transverse to the length of the ski irrespective of whether this dis-, placement force is applied laterally or vertically or in some intermediate, direction. The ski binding includes a spring loaded latching element with a broad tapered tongue which is pressed into engagement with a socket in the heel of the ski boot.
