The underside of a heel holder is guided on a guide rail secured to the upper side of a ski. The guide rail has at least one set of toothed serrations associated with a locking member having corresponding counter serrations. The locking member can be pivoted about a transverse axis. The locking member projects beyond the heel holder toward the tail end of the ski and can be lifted against the force of a spring from and out of the locked position by means of a screw driver. After release by the screw driver, the locking member is swung by the spring into the locked position. A guard plate is provided for covering the teeth of the toothed serrations to prevent damage thereto by the screw driver.

Heel holder, in particular for a rental ski

A safety ski binding includes a jaw for releasably holding a ski boot sole, which jaw has strain sensors which produce electrical signals in response to forces exerted on the jaw and an electrically operated release mechanism. A plug board provided in the jaw behind a protective cover is connected electrically to a control circuit which is responsive to the strain sensors and controls the release mechanism. A replaceable plug-in unit insertable in the plug board determines the release characteristics of the jaw on the basis of the skier's ability level and personal characteristics. In one embodiment, the plug-in unit contains fixed circuit components which define the ability level and variable circuit components adjustable to define the personal characteristics. In another embodiment, the plug-in unit contains a program storage or a micro-processor which defines the ability level and personal characteristics.
