Abstract
Abstract Releasable heel retainer for a ski binding that is provided on the base portion secured to the ski pivotally mounted for movement about a horizontal axis that extends longitudinally of the ski and the housing of which carries a sole holder, where inside the housing a release is disposed that acts against spring effect and causes the release of the ski boot under excessive load, which housing is displaceably journalled and supported on the base at the end remote from the sole retainer so that there results a slide crank type connection of the housing on the base, and displaceable mounting of the housing on the base is in the form of a guide means that protects the housing against rising from the base, and where furthermore a means is provided that is releasable manually or by a foot-step that fixes the open position of the retainer, and which heel retainer includes the improvement of the arrangement serving as the crank pivotally engaging the spring and this linkage slidingly engages a curved slot of the base which slot rises upwardly in the direction toward the sole retaining element, and where the linkage of the crank secured to the housing is disposed in a known manner ahead of the linkage of the crank on the base part secured to the ski.
