Abstract: Ski binding, in particular a touring, telemark or cross-country binding, with a front retaining element associated with the front end of the sole, a back retaining element designed to engage the front part of the sole of a ski boot or the heel of the boot and a tensioning device connecting the front and back retaining elements to one another, which allows the front and back retaining elements to be locked to the ski boot and, in particular, allows the heel of the boot to be raised from the ski while in the locked state, such that at least one spring-loaded release mechanism is associated with the tensioning device in order to release the lock between ski binding and ski boot under the action of a torque that exceeds a specified threshold magnitude and is exerted on the ski or boot about an upright axis of rotation, and/or of a force manually exerted on an essentially only positive-fit locking element.

Abstract: A ski binding arrangement for cross-country or telemark binding, and a ski boot adapted thereto with a boot sole, such that the arrangement includes a first engagement element on the binding side and a second engagement element on the boot side in the region of the front end of the boot sole, which in the position for use are engaged with one another and keep the ski boot in linear or areal contact with a ski or a binding plate attached to the ski, wherein the underside of the boot sole in the front region is conversely curved in the long direction and the first and second engagement elements are adapted to one another such that, when the back end of the boot is raised or lowered, the boot sole makes a rolling motion associated with a longitudinal shift of the contact line or area on the ski or binding plate and, by a lowering or raising of the front end of the boot, e.g. movement in the direction opposite to that of the back end.

Abstract: A combination of a ski binding (10), particularly cross-country, touring or telemark binding, and of a boot (11) adapted thereto are shown, the front end of which is held by a resiliently biased clamp member (12; 48) in the binding (10) in such a way that the heel (13) of the boot (11) can be freely raised during ski touring or cross-country skiing. The clamp member (12; 48) engages on the forward sole (15) of the boot (11) particularly between the ball area and the rear end of the same, and preferably on the underside of the boot forward sole (15).

Abstract: Ski-binding arrangement to fix a ski boot to a ski, in particular a touring or cross-country ski, with a latch mechanism to fix the front end of the ski boot to the ski in such a way that the metatarsus and heel can be raised freely from the upper surface of the ski. The latch mechanism can be attached to a holding plate (10). The holding plate (10) in turn is so disposed that it can swing out to the sides about an axis perpendicular to the surface of the ski against the action of spring-braced elements (12) of a locking mechanism (11), the lateral swinging movement being so extensive that the plate is completely freed from the ski. The holding plate (10) is supported by way of its extreme front end (13) on a retaining part (14) mounted on the upper surface (19) of the ski, the plate (10) being so disposed that it can swing sideways about said front end. The locking mechanism (11) is associated with the back end of the holding plate (10).

Abstract: A binding for cross-country or touring skis for use in combination with ski boots engagement elements for receiving complementary engagement elements provided on the boots. The engagement elements of the binding are disposed within a binding housing (14) establishing a pivot-type connection. A pivot (18) extends crosswise to the longitudinal extension of the boot. The engagement elements of the binding include a retaining hook (26) engaging behind the pivot (18), cooperating to constitute a hinge joint. The hook is movable between a closing position and a releasing position, and a flexor (80) is provided on the binding for resiliently returning the boot from a raised position to a position parallel to the ski. The sole of the boot includes a pivot (18) which is supported on the side of the binding against a separate supporting bearing made of metal or the like.
