Definitions

• the invention relates to a safety ski binding with a pivotable sole plate in a horizontal plane, which is inseparably connected to the ski and with a sole holder attached to the sole plate for the heel end of the sole of a ski shoe with a first locking element, which has a locking surface on a spring-loaded the sole plate hinged pawl cooperates and monitors a pivoting of the sole holder in a vertical plane and with a second latching element which cooperates with a second latching surface attached to the ski and monitors a pivoting of the sole holder or the sole plate in the horizontal plane.
• a safety ski binding is known (DE-AS 22 20 040), which has a base on the heel side, which is pivotally mounted on a base plate about a vertical axis and on which a sole holder for the heel-side end of the sole of a ski shoe is articulated in such a way that it is attached to a horizontally directed axis is pivotable, whereby it releases the ski boot when triggered.
• the vertical deflection is monitored by the interaction of a locking element and a spring-loaded locking surface formed on a pivotable pawl. When the sole holder is swiveled up, the pawl is pressed to the side against the force of a spring by the latching element.
• a further locking element is attached to the sole holder, which interacts with a curved track attached to the ski in such a way that in the rest position no lateral deflection takes place until a certain transverse force is reached and a lateral displacement only when a certain size of the transverse force is exceeded.
• pivoting of the sole holder takes place, the sole holder being pivoted vertically by the rolling of the second latching element on the cam track and the spring loading the pawl being compressed. If a certain limit force is exceeded, the sole holder is also triggered in the vertical plane.
• a safety ski binding is also known (DE-AS 24 29 609), in which the sole holder for the heel-side end of the sole of a ski shoe is constructed in two parts, the part engaging with the sole around a vertical axis and the second part around the sole holder a horizontal axis is pivotable.
• the lateral pivoting i.e. pivoting of the sole holder in a horizontal plane, is monitored by a spring-loaded ball catch.
• the pivoting of the sole holder in the vertical plane is monitored by a spring-loaded angle lever that slides on an inclined plane. The free end of the angle lever slides downward on a vertical pivot on the spring securing the ball locking, the spring characteristic of this spring changing accordingly.
• the lateral release force can be set as a function of the vertical deflection by suitable shaping of the recess, and conversely the vertical force required for the release can be a function of the lateral deflection, such bindings have not become established, since extremely high accuracy requirements are required for the shaping of the corresponding locking surfaces are provided that are not feasible with such mass articles.
• a high degree of wear occurs, which makes the binding prone to failure.
• a subsequent change in the relationship between the vertical and lateral release force is not possible.
• the invention has for its object a
• this object is achieved by the features provided in the characterizing part of claim 1. Due to the arrangement according to the invention, there are defined force ratios in each phase even in the event of a lintel, a deflection of the sole holder in one vertical plane or horizontal plane in each case causing a decrease in the corresponding triggering force in the other plane. By providing two separate springs for the locking elements, the ratio of the lateral to the vertical release force can be individually adjusted and adapted to the appropriate driving skill and driving style.
• the invention has the advantage that, with the greatest structural simplicity and operational safety, a mutual influencing of the vertical and horizontal deflection is ensured at all times by the fact that the release of the ski boot sole blocks; Locking device between the two Tabs of the pawl is displaced in the case of a pure vertical deflection of the sole holder in such a way that it comes in the immediate vicinity of an extension formed on the second locking element. A slight lateral pivoting of the sole plate then releases the locking device, causing the sole holder to fold up and release the ski boot sole. When the sole plate is pivoted horizontally, the extension is displaced such that it finally comes in the immediate vicinity of the locking device, which is preferably designed as a toggle lever. If a certain horizontal deflection curve is exceeded, the knee lever is unlocked and the sole holder releases the ski boot sole by opening it in the vertical plane.
• the toggle lever which connects the two tabs of the pawl, is arranged in such a way that it is not subjected to the full force acting on the two tabs, but rather that this force is disassembled beforehand, for example over an inclined plane, in such a way that the toggle lever only a part of the trigger force acts. Accordingly, the release force for the toggle lever also decreases, so that the release characteristic becomes a smooth curve without undesired maxima.

• the angle lever 34 is pivoted. (to the right in the drawing), whereby the spring 40 is compressed and the horizontal pivoting of the sole plate opposes an increasing restoring force.
• the extension 36 simultaneously approaches the toggle lever 33 arranged above it. If the lateral deflection is continued to the point at which the extension 36 comes into direct engagement with the toggle lever 33, which state in FIG. 4 is shown, the extension 36 pushes the toggle lever 33 'upwards, whereby the two tabs 29, 31 forming the pawl are decoupled and the latching surface 28 can deflect to the right.

Therefore occurs when already done, within the elasticity area lying vertical pivoting of the sole holder additionally a horizontal pivoting of the sole plate, the toggle lever 33 is opened before reaching the maximum horizontal deflection due to the shorter distance between the extension 36 and the lever 33, and thus the release of the shoe is initiated.

• the arrangement described has the advantage that the locking device, ie the toggle lever 33 ', is only acted upon by part of the triggering force.
• the inclination of the inclined plane or cam surface 70 can be selected so that, for example, only 10% of this force, for example 14 kp, is applied to the toggle lever with a release force of 140 kp in total. Assuming a friction coefficient for rolling friction of 0.1, this means a trigger force of only 1.4 kp. Compared to the embodiment according to FIGS. 1 to 7, this would be a reduction to 10%.

• These overlapping areas are preferably designed such that an axial displacement of the ends of the sole plate relative to the ski surface is possible. This ensures that the ski can swing freely and through the mounted binding in the middle its vibration behavior is not adversely affected.
• This effect is reinforced by the fact that the pivot pin 12 'is preferably mounted in the sole plate in such a way that it allows the sole plate to be displaced vertically relative to the pin body. This can be solved, for example, by a plastic sleeve slipped over the pin, which engages in a corresponding recess in the soleplate.
