  • the lever arm H1 extends from the pivot axis B 4 to the transition of the holding element 4 over a length L1 into the bearing section 43 of the holding element body 40 and includes a part of the coupling section.
  • the second lever arm H2 extends from the pivot axis B 4 to the free end of the holding element 4 over a length L2 and includes a part of the coupling section 42 and the engagement section 41.
  • the length L1, L2 of the respective lever arm H1, H2 or the ratio The lever arm lengths relative to each other are determined by the position of the pivot axis B 4 on the coupling area 42 of the holding element 4.
  • the rail S is firmly connected to the ski body, not shown, and in the exemplary embodiment it is connected by means of screws.
  • the Figure 3 For example, four screws are shown, two on each side of the heel holder 1, which are arranged mirrored with respect to a central longitudinal axis of the heel holder 1.
  • the Figure 5 shows a view from above of the heel holder housing 3 with the heel holder housing parts 32, 33 and next to it the heel holder housing part 34.
  • the underside of the heel holder housing part 34 can be seen, which rests directly on the heel holder housing part 32 when the heel holder housing part 34 closes the heel holder housing 3 (see Figure 2 ).
  • the receptacle 11 for the bearing section 43 of the holding element body 40 is formed in the heel holder housing 3.
  • the shape of the receptacle 11 essentially corresponds to the shape of the bearing section 43.
  • the width of the receptacle 11 essentially corresponds to the diameter of the holding element body 40 in the area of the bearing section 43.
  • the receptacle 11 is shaped such that the holding element body 40 lying in the receptacle 11 essentially cannot be displaced in the longitudinal direction X.
  • the third heel holder housing part 34 forms a cover of the heel holder housing 3. It comprises an engagement structure 34a, the shape of which essentially corresponds to the shape of the receptacle 11 in the heel holder housing 3.
  • the engagement structure 34a can be a bead-shaped elevation or also a receptacle in the form of a groove for a part of the bearing section 43 of the holding element body 40.
  • the engagement structure 34a is preferably bead-shaped and engages in the receptacle 11 in the heel holder housing 3 when the third heel holder housing part 34 is connected to the Heel holder housing 3 is connected.
  • the engagement structure 34a can be shaped so that it tensions the holding element body 40 in the longitudinal direction X towards the toe holder.
  • the engagement structure 34a can rest on the holding element body 40 in the area of the bearing section 43, so that the holding element body 40 is fixed transversely to the longitudinal direction at least in this area.
  • the engagement structure 34a can rest on the bearing section 43 of the holding element body 40 only in one point or a section, namely in a point or section that defines a pivot axis transverse to the longitudinal direction and at least substantially parallel to a ski surface about which the holding element body 40 pivots can if the holding elements 4, 5 are moved outwards and upwards in the through openings 38, 39 in the side wall 31 of the heel holder housing 3 when the heel holder 1 is triggered.
  • the Figure 6 shows two views of the heel holder 1 with different positions of the pivot axes B 4 , B 5 .
  • the respective position of the pivot axes B 4 , B 5 determined the length ratio of lever 1 to lever 2 ( Figure 4 ) and thus the force that is necessary for a vertical release of the ski binding or the heel holder 1.
  • pivot axes B 4 , B 5 are in a position that determines or defines the minimum triggering force.
  • Lever 2 has a maximum length L2
  • lever 1 has a minimum length L1.
  • the pivot axes B 4 , B 5 are closer to the side wall 31 of the heel holder housing 3 in the longitudinal direction The triggering force for the vertical release of the heel holder 1 is therefore greater in the left illustration than in the right illustration.
