Definitions

• the invention relates to a safety ski binding, in particular heel holder, according to the preamble of patent claim 1.
• a heel holder of the type mentioned is described in DE-OS 17 03 719.
• This version is a safety ski binding that releases the shoe both in the vertical and in the horizontal direction.
• This binding has a spring-loaded locking device which interacts with two locking elements. One of these locking elements blocks the movement of the binding upwards, the other locking element blocks the movement to the side. If a load occurs in one direction, the associated latching element presses the latching device back against the force of the spring and thereby reduces the spring force required for triggering when pivoting in the direction perpendicular thereto. Moving the latching device in one direction loosens the latching in the direction perpendicular thereto, since the latching device moves away from the associated latching element.
• a single latching device which interacts both with a latching element for the vertical movement and with a latching element for the horizontal movement, there are fundamental difficulties in coordinating the two latches.
• AT-PS 380 17 * shows a heel holder which shows a housing with a latching device which can be pivoted about a vertical axis fixed to the base plate against the force of a spring.
• the latching device consists of two levers, both of which are articulated on the same axis on the housing, the lever controlling the horizontal pivoting being accommodated in a recess in the lever controlling the vertical pivoting.
• the lever that controls the horizontal pivoting is supported resiliently on the housing and carries a control cam that interacts with a roller mounted on an extension of the base plate attached to the ski.
• the plate which carries the extension can be designed as a ski-fixed base plate or as a pivot plate which can be rotated about a ski-fixed vertical axis.
• the sole holder, which is held in the driving position by the latching device, can be articulated either on the housing or on the plate carrying the extension.
• the features of claim 9 enable diagonal control in a heel holder in which the sole holder is articulated on the housing and can be pivoted about a vertical axis of the ski-fixed base plate, the base plate also carrying the extension.
• a heel holder can be realized, which is connected to a swivel plate and, in cooperation with a toe piece, represents a so-called center-point binding.
• the housing is provided on a swivel plate rotatable about the vertical axis of the ski-fixed base plate, the sole holder being articulated on the housing and the extension being formed on the base plate.
• the housing is integrally formed with the ski-fixed base plate and the extension is provided on the pivot plate rotatably mounted about the vertical axis of the base plate, the sole holder being articulated at the rear end of the pivot plate.
• the features of claims 12 and 1 * characterize an advantageous design of the control cam on the sole holder and enable the release lever to be arranged correctly.

• the locking rocker 11 rests with its locking lug 11c on the control cam 1 * c.
• the horizontal bar of the locking rocker 11 has a hole 11d in its center for a bolt 16, to which a release lever 17 is articulated, which with its short, U-shaped arm 17a on the lower part of the sole holder 1 * attacks.
