Abstract: The invention relates to a heel-piece for a safety ski binding, the heel-piece being released when the load on the binding exceeds a specified limit. A link mechanism is mounted on the heel-piece for connecting the sole-holder to the binding plate of the ski. The link mechanism is engaged by two spindles, which in the operational position of the heel-piece are transverse to the ski and parallel to its surface. The sole-holder is connected by the link mechanism to the binding plate and to the spindles, these components being mutually engaged by a spring-loaded detent/detent-track. In order to achieve compensation for defective settings of the heel-holder, the invention provides that the sole-holder is connected to the binding plate only by the link mechanism. Further, one of the components of the detent/detent-track system is connected with one of the binding plate and the sole-holder and the other component of the detent/detent-track is connected with the other of the binding plate and the sole holder.

Abstract: The present invention concerns a ski safety binding including an electronic analyzer connected to force pickups that emit electrical signals. An electric power supply such as a battery is provided. An electromechanical release element controls a locking mechanism for acting on a heel holder or piece. The electromechanical release element has at least one stop member. To assure high reliability even in the severe weather conditions, the present invention mounts the electromechanical release member inside a well sealed housing. A drive control member is positioned in sealed manner through the wall of the housing. The drive control member includes a shaft and controls the locking mechanism that acts on the heel piece.

Abstract: A ski binding having a hook element arranged at the tip of a ski shoe, a bearing block secured to the ski and having a receiving part for the hook element, and a locking element supported on the bearing block and having at least one locking protuberance. The locking element locks the hook element against movement on the receiving part by means of a spring force. The hook element has a wall-like member or hook bar which extends in the skiing position at least approximately vertically upwardly relative to the upper side of the ski. The receiving part has guide bars thereon which extend approximately perpendicularly to the upper side of the ski and which are designed to receive the hook bar therein.
