Abstract

The invention relates to a ski binding (1) with a toe-holding unit (2) and a heel-holding unit (3). Release mechanisms (8) are integrated in the latter and can be set to different releasing forces. Detachably fastened on the ski are longitudinal guidance devices (5, 6) for the toe-holding and/or heel-holding unit (2, 3), which are movably connected to the connecting element (4). The toe-holding and/or heel-holding unit (2, 3) can be fixed by an arresting device (17) for fixing the toe-holding unit (2) in a longitudinal guidance device (5) and/or a transverse guidance device (74).

Claims7

Dependent claims

A ski binding for a longitudinally extending ski comprising:

a toe clamp with an adjustable release mechanism mounted on the ski;
a heel clamp with a second adjustable release mechanism mounted on the ski in operative relationship to said toe clamp;
connection means for altering the position of at least one of said clamps with respect to the other of said clamps, including
a notched track fastenable on the ski,
an arresting device including a swivel arm having two ends and a central portion thereof, said swivel arm extending parallel to the longitudinal direction of the ski and being pivotably connected to at least one of the clamps, said swivel arm being pivotal in a plane perpendicular to the top side of the ski about an axis which is generally parallel to the top surface of the ski and generally perpendicular to the longitudinal direction of the ski, the pivot axis being located at one end of said swivel arm;
an actuating member formed as a cylindrical cam having an end with a cutout for engaging said swivel arm at the end opposite the pivot axis and pivoting said swivel arm between two terminal positions including a locked position in which said at least one clamp is fixed with respect to said track and an unlocked position in which said at least one clamp can be moved along said track, in the locked position said central portion of said swivel arm being removably engaged with said noticed track, said cylindrical cam rotatably mounted with the clamp and being rotatable about its central axis which is generally parallel to the longitudinal direction of the ski and said swivel arm, the release mechanism being accessible and adjustable independently of the position of said pin and said swivel arm;
and
spring means for continuously biasing said swivel arm toward the locked position in the direction of said notched track and the ski, the cutout of said cylindrical cam providing a surface in each terminal position where said spring means and said swivel arm exert force on said end of said cylindrical cam in a direction transverse to its direction of rotation so that said swivel arm does not effect the moment of said cylindrical cam and is maintained in the terminal position until external actuation of said cylindrical cam.
