Abstract: A front jaw having two laterally spaced toggle levers which can be swung out against the force of a release spring housed in a housing and through which housing extends a pull rod. In order to cause in this front jaw during a backward twisting fall an initial tension of the release spring and thus a reduction in the work of the swinging-out toggle lever, the invention provides that the two shorter lever arms of the toggle levers are loaded by a release spring acting through a pull rod onto an angular intermediate lever supported in the lower area of the housing on a first pivot axle.

Abstract: A front jaw for a ski binding which prevents dirt from penetrating from above into a housing of the front jaw. The front jaw includes a release spring arranged within the housing. The release spring loads a pull rod extending through the spring, which pull rod acts through a release plate onto short lever arms of two toggle levers which are pivotal about vertical axes on a support part. Long lever arms of the toggle levers are designed as a sole holders for a ski boot. The support part has a through opening for the pull rod and a front support surface which rests at least partially on a rear cross wall of the housing. An insert plate is arranged between the support part and the rear cross wall of the housing and essentially rests on the rear cross wall and extends vertically, and on which insert plate the support part rests in certain areas.
