For snowboard bindings, many participants have long desired a so-called step-in binding, that is, a binding one could simply step into like a ski binding, without the snowboarder having to bend down to operate parts of the binding, such as locking stirrups. On the other hand, safety bindings that would permit complete release of the shoe from the snowboard in case of excessive force applied are still problematic for snowboards, since the resulting safety problems for participants and bystanders have not yet been satisfactorily solved, despite numerous proposals. Finally, the very serious problem of space also comes up in regard to snowboard bindings. The snowboarder is standing essentially transverse to the travel direction of the board, which means in practice that the angle between shoe longitudinal axis and snowboard longitudinal axis is between 45° and 90°, with some snowboarders even orienting their rear foot backwards, that is, at an angle of greater than 90° with respect to the direction of travel. Since snowboards, particularly the so-called alpine boards for snowboarders on prepared slopes, are becoming narrower and narrower, the toe of the boot and the heel of the ski boot are already projecting out over the contour of the snowboard. The principle can therefore be established that a snowboard binding must not project beyond the toe or heel of the boot, since this could lead to projecting binding parts touching the snow when the board is turned on edge. For this reason, conventional ski bindings that have the step-in function are not suitable for snowboards.
In the embodiment example of FIG. 12, the pins 9 located in the interior of the second binding part 6 are connected by articulated levers 60,60' to the pivoting lever 40, with the ends of the articulated lever 60,60' each being connected by a pivot joint to the pins 9,9' and the pivoting lever 40. The central axis of the pivoting lever 40 runs perpendicular to the central axis of the pins 9,9'. One central axis of the articulated lever 60,60', by contrast, is positioned at an angle of roughly 45° to the central axis of the pivoting lever 40. The two pivoting levers 60,60' are parallel to one another and are each connected to one end of the pivoting lever 40. If the pivoting lever 40 is rotated about its pivot axis 41 (clockwise in FIG. 12), then the articulated levers 60,60' each apply a tensile force to the pins 9,9' and pull them into the interior of the second binding part 6. The tensile element 12 is connected to one end of the pivoting lever 40. For this purpose, a blind hole 63 and a continuing smaller through-hole 64 are provided on the pivoting lever. The tensile element 12 is threaded through the through-hole 64 and thickened at its end by a knot, a press-on sleeve or the like so that it can no longer be pulled back through the through-hole 64. The thickened end is then arranged to be sunk into the blind hole 63.
FIG. 12a shows an enlarged detail view of a specific aspect of FIG. 12, namely, the guiding of the pin 9 through the wall of the second binding part 6. Since a high degree of flexibility regarding the motions of the foot in all directions is desirable in snowboarding, but most snowboard boots in use with plate bindings have a relatively hard outer shell, this flexibility cannot be achieved by the shoe alone. For this reason, the pin 9 is flexibly supported in relation to the second binding part 6, which is rigidly connected to the boot. To this end, the pin 9 is supported so as to be displaceable in a metal casing 69, which is in turn connected to the second binding part 6 by an elastic casing 68. This elastic casing 68 can consist, for instance, of rubber or some other resilient material, such as an elastic plastic. In manufacturing the second binding part 6, the plastic "shell" of which is produced by injection molding technology, it is possible to mold on this flexible casing 68 in a second work step in the same injection molding form, which means that the casing 68 also obtains a very good connection to the binding part 6. Not only are shocks dampened and absorbed by this resilient supporting of the pins, which absorb the essential forces between the snowboard and the boot, the boot can also be tilted in an angle of 1°-3° perpendicular to the longitudinal direction, which considerably increases comfort in use.
