Safety binding

The invention relates to a safety ski binding with a release mechanism, preferably by means of a release mechanism movable, releasing the Schjsshuh in case of overuse Heel holder and a lanyard.

For safety bindings, especially for those with automatic heel, some special designs and arrangements of lanyards have already been proposed, The main point of departure was that the lanyard did not have the effect of safety ski binding may be lifted, i.e. it must be designed or arranged in such a way that the release of the shoe when the safety

binding is not hindered by the lanyard, and of course the purpose of the lanyard is also appropriate open safety binding and released shoe, a loose connection between shoe and ski should be maintained.

In this context, for example, the proposal has become known, to train the lanyard as a rubber rope. When the safety education opens up, the shoe can come off the ski remove, stretching the gurrjnioeil. However, there is the risk of the ski against the skier after a fall as a result of the retraction effect of the tightened Gununi rope quickly, which has already led to significant injuries.

Another popular suggestion is to take Use spring-loaded rollers on which the lanyard is normally wound by spring force. At the In the event of a fall, the lanyard can be pulled off the bolls against the spring force. On the other hand, the proposal has become known to use a lanyard that is considerably longer than the distance between the shoe and the ski, with the shoe or Ankle strap an eyelet is arranged in which the folded Lanyard is inserted. With these two arrangements, however, the lanyard cannot be tightened and laced in such a way that the foot in the shoe and the shoe on the ski provide additional support, especially on the side Stops.

The invention is therefore based on the object of a To create pan strap arrangement for a safety ski binding with heel holder, which tightly laces the lanyard permitted without the safety function of the safety ski binding to affect.

This is achieved according to the invention in that the lanyard or an extension piece connected to the lanyard at a distance corresponding to the release length in front of its rear end relative to the ski or binding a locking device coupled to the heel holder or its release mechanism can be fixed.

The .Erfindung is based on the drawings through exemplary embodiments explained in more detail, without being limited thereto.

Fig. 5 shows a side view, partially in section Another embodiment of a binding according to the invention.

The binding parts shown in the drawings Figs belong to a so-called "automatic heel", consisting essentially of a heel holder 1 and a Trigger mechanism, arranged in the housing 2, the heel holder 1, as a result of the function of the release mechanism, releases the ski boot in the event of overuse. Of simplicity For the sake of the drawings, the paragraph holder is shown schematically shown as a pivotable lever about the axis 3, as in the case of the representation of the automatic heel, the one may have known construction, omitted all details not relating to the subject matter of the invention became.

In the embodiment according to FIGS. 1 to 4, a guide eyelet 4 is attached to the heel holder 1, which pops up in the event of a fall, in which the rear lanyard part 5 at opened paragraph holder 1 can be easily moved. The rear 2nde of the lanyard part 5 is attached to a eyelet 6 attached. In the vicinity of the front end, the lanyard part 5 has a metal-reinforced elongated eyelet 7 (FIG. 4). As FIG. 2 shows, both the guide eye 4 and the heel holder 1, which pops up during the fall, has an elongated hole 8. On the housing 2 of the automatic heel and in a fixed

connection with this a pin or bolt 9 is provided, which protrudes through the attachment holder and the guide eye 4- when the automatic heel is closed.

When buckling the ski, the skier pushes the rear lanyard part 5 in the direction of arrow A through the guide eyelet 4 with the automatic heel open until the elongated eyelet 7 of the belt 5 coincides with the elongated hole 8 of the guide eyelet M- , whereby a stop (not shown) is the Finding the right position can make it easier. If the skier then presses the heel holder 1 of the automatic heel down in a known manner, the pin or bolt 9 engages in the guide eyelet M and the elongated eyelet 7. The rear lanyard part 5 is thereby locked, üin a commercially available long leather strap 11 attached to a ring, half-ring or triangle 10 can now be tied tightly around the ski boot and thus gives it an additional lateral hold.

If the automatic heel opens as a result of a fall, the heel holder 1 pivots upwards and the pin or bolt 9 is pulled out of the guide eye M and from the elongated hole 7 of the lanyard part 5, so that the gills 5 against the direction of arrow A through the guide eye M can slide, With a suitable length of the lanyard part 5, the ski boot is securely released on this 7 / ice.

In Fig. 5 is another embodiment of the invention shown. The! Lanyard 12 is expediently there made of wire or a plastic rope that is attached to the heel holder 1 of the automatic heel Dog eyelet 13 and through a hole 14 into the interior (housing 2) the automatic heel and can be wound on a roll or roller 15. The winding can be e.g. the restoring force of a spiral spring 17 attached to the stationary axle 16 and the roller or cylinder 15 takes place or carried out in a suitable manner by hand using a crank will. The lanyard 12 is locked on the V / eise that the roller or roller 15 when closing the automatic heel is latched with a pin 18 or a locking wedge. The axis 16 can be arranged in any suitable position be. However, it is also a locking mechanism for the lanyard 12 according to Fig. 1 to 4- possible.
