Boot retaining unit with damping
A boot retaining unit of a ski binding or snowboard binding, including at least one boot retaining element, a restoring spring for the boot retaining element, and a damping device for absorbing short, hard impacts, wherein the at least one boot retaining element and the damping device are connected via a translation mechanism, and the translation mechanism translates a deflection of the at least one boot retaining element into a larger deflection of the damping device.
1. A boot retaining unit of a ski binding or snowboard binding, comprising
a) at least one boot retaining element,
b) a restoring spring for the boot retaining element, and
c) a damping device for absorbing short, hard impacts, wherein
d) the at least one boot retaining element and the damping device are connected via a translation mechanism, and
e) the translation mechanism translates a deflection of the at least one boot retaining element into a larger deflection of the damping device.
2. The boot retaining unit according to claim 1 , wherein the translation mechanism comprises at least one transmitting element which transmits the deflection of the at least one boot retaining element onto a damper of the damping device.
3. The boot retaining unit according to claim 2 , wherein the transmitting element comprises a first end which is coupled to the at least one boot retaining element and a second end which is coupled to the damper.
4. The boot retaining unit according to claim 3 , wherein the first end is coupled to the boot retaining element in a pivot joint and the second end is coupled to the damper in a pivot joint.
5. The boot retaining unit according to claim 4 , wherein the boot retaining element forms a first lever arm of a lever and the transmitting element forms a second lever arm of the lever and the first and second lever arms are of different lengths.
6. The boot retaining unit according to claim 3 , wherein the translation mechanism comprises two transmitting elements which are coupled to the damper in the pivot joint.
7. The boot retaining unit according to claim 2 , wherein the damper is connected to the ski or snowboard in a pivot joint.
8. The boot retaining unit according to claim 2 , wherein the damper is arranged transverse or parallel to a longitudinal axis of the ski binding or snowboard binding.
9. The boot retaining unit according to claim 1 , wherein the restoring spring for the boot retaining element is simultaneously a spring for restoring the damping device from an activated state to its resting state.
10. The boot retaining unit according to claim 1 , wherein the restoring spring is arranged transverse or parallel to a longitudinal axis of the ski binding or snowboard binding.
11. The boot retaining unit according to claim 1 , wherein the at least one boot retaining element is coupled to the translation mechanism directly or via a linkage.
12. The boot retaining unit according to claim 1 , wherein the damping device comprises a damper in the form of a damper housing which is filled with a damping agent and which comprises a damper piston.
13. The boot retaining unit according to claim 12 , wherein the restoring spring surrounds the damper housing and the damper piston.
14. The boot retaining unit according to claim 1 , wherein the damping device comprises a damper in the form of a mass pendulum.
