  • Patent number: 5050903
    Abstract: The invention relates to a holding unit, in particular a toe unit, for safety ski bindings, which has a sole hold-down arranged on a bolt and two angle levers pivotably mounted about a spindle each, arranged on a supporting member, the angle levers being adapted to swivel out to the side against the force of a spring. The sole hold-down is adapted to move upwards against the force of the spring when there is a force acting vertically upwards on it, via a compensating lever, which bears against one of the angle levers each either directly or with an intermediate lever interposed. The bolt is guided displaceably in the vertical direction and, if there is an overload, is acted on by a wedge element which is guided on the supporting member and against which the ski boot bears.In this arrangement there is a compensation for the frictional forces additionally occuring on the sole hold-down in the event of a twisting fall both backwards and forwards.
