Flexor unit and binding containing it

摘要

The present invention relates to a flexor device for a ski, and defines a flexor unit (10) for a ski binding (2), in particular a ski binding (2) for a cross country or touring ski (1), for interacting with the ski boot or shoe (3) of the user of the ski (1). The flexor unit (10) comprises a rotatably mountable transmission element (20) for contacting the front and/or sole portion of the ski boot or shoe (3); the rotatably mountable transmission element (20) further comprising a holding portion (27) which is sized and shaped to receive a pivot axis (4) of the ski boot or shoe (3). This pivot axis (4) being used to pivotally attach the ski boot or shoe (3) to the ski (1), so as to allow the heel of the ski boot or shoe (3) to be lifted. Biasing means (30) are also provided for acting on the transmission element (20) so as to rotate the transmission element (20) in a direction such that it would act against the ski boot or shoe (3), so as to force the heel of the ski boot or shoe (3) around into contact with the ski (1). The axis of rotation (21) of the rotatably mountable transmission element (20) is provided by the ski boot or shoe (3) holding portion (27) and advantageously coincides with the axis of rotation of the ski boot or shoe (3) provided by the pivot axis (4), such that when in use, no relative translational motion between the front and/or sole portion of the ski boot or shoe (3) and the rotatably mountable transmission element (20) would occur.
