Abstract: A release binding for skis is usable both for touring or cross-country and downhill runs. It comprises a touring plate which has a front end portion which is pivotally mounted at its front end for movement about a horizontal axis which extends transverse to the longitudinal axis of the ski. The touring plate also includes a rear portion which is connected through a length adjustment mechanism to a heel holder portion. A sole holder is connected to the front end of the touring plate and it carries a blocking part which is seated on the touring plate and it includes an upstanding part adjacent its front end which is disposed above the horizontal pivotal axis of the touring plate which bears against a blocking element which is mounted on the ski ahead of the touring plate and is biased by a spring against the blocking part. When the touring plate is pivoted upwardly during a cross-country run, the blocking element is displaced rearwardly against the biasing force of the spring.

Abstract: A ski boot heel release binding, comprises a mounting base plate which is adjustably connected to a toe jaw part via a touring plate. The base plate includes an upstanding portion which supports a transversely positioned heel mounting pivot. A heel holder includes a slot which is vertically elongated on the holder in the closed position which forms a guide for the mounting pivot to pivotally mount the heel holder on the base plate upstanding portion. The heel holder includes a heel engaging sole-holder portion and a treadnose portion which may be engaged by the boot when in an open position to press the heel holder downwardly by rotation on its pivot to a closed position. A bolt pivot is carried on the heel holder at the lower end on the end opposite the nose and it rides in a guideway of a rotatable disc which is mounted on the upstanding portion for rotation thereon.
