Fix the locking member 24. In Fig. 5, however, the shift lever is pivoted down and holds the sole holder 17 against the force of the spring 18 in a position releasing the shoe sole, so that the ski boot 11 can be removed from the binding.

In the event of a frontal fall, an upwardly directed one engages over the sole holder 17 on the housing 14 Force that leads to an involuntary release of the lock between the bolt 19 and the Haiteglied 15 against the force of the spring 20 leads. As a result, the outer plate parts 12, 13 with the housing 14 in the position according to FIG. 2 move. After the fall has ended, a If you step lightly with your heel, the lock will be automatically re-established. Through more or screwing in the screw plug 22 less far, the spring force can be changed.

In the event of a twisting fall, the ski boot 11 rotates together with the ball locking 7/8 after loosening the ball catch of the sole plate 1 around the pin 6.

After the fall has ended, the Locking can be restored automatically. The spring force of the ball locking device can also adjust.

Since both a twisting fall and a head-on fall, the ski boot 11 over the sole holder 10, 17 remains connected to the sole plate 1, which in turn is connected to the ski 5 by means of the pin 6 there is no need for a special lanyard. This has besides the opening already mentioned the further advantage that the ski can be put on and taken off quickly and easily. You can switch from “descent” to “ascent” with a single movement.

For ascent, the ski boot can move freely from its position according to FIG. 4 into a lift-off position pivot, which according to F i g. 2 corresponds, with only the shift lever in contrast to FIG. 2 in which is pivoted upwards, in which, as said above, it is fixed during the ascent.
