Definitions

  • the present invention relates to a buttock device with a ski brake for a ski binding, in particular for touring ski binding. Furthermore, the present invention describes a ski binding, in particular a touring ski binding, for a ski.
  • Ski bindings for ski in particular for touring skis, firmly fasten the ski boot of a skier in a downhill mode with a ski.
  • the ski bindings have a safety release function, so that the ski bindings in certain situations, such as a fall of the skier, automatically open to prevent injury to the skier.
  • a ski binding for touring skis has to fulfill a multitude of different functions in addition to the safety release function.
  • the ski boot must be freely pivotable about its toe area relative to the ski to allow for skiing along a mountainside.
  • the ski binding During downhill skiing in downhill mode, the ski binding must secure the ski boot firmly to the surface of the ski, so that no relative pivoting of the ski boot over the ski tip is possible.
  • the ski binding must fulfill the safety release functions, so that in the event of a fall of the skier, the boot is released from the binding in order to avoid injury to the skier.
  • ski brakes To brake the ski in downhill mode after a fall of the skier, ski brakes are used. Ski brakes drive or pivot after releasing the ski from the ski boot of the skier and engage in the snow to slow down the ski.
  • ski binding In addition to the above-described functions of the ski binding, it is necessary that the ski binding is comfortable to use, so that between the individual modes, e.g. Ski touring and downhill, comfortable and can be changed quickly. Complex modifications to the ski binding while switching between modes are uncomfortable. At the same time, the complexity of the system must remain low in order to minimize the susceptibility to failure and the weight of the ski binding.

  • the spring force of the biasing spring may bias the rod to a position in which the rod rotates the adjustment lever to a position in which the stopper lever is in the ski braking mode.
  • the adjustment lever may be configured such that in a downhill mode of the buttock device, a weight of the skier acts on the adjustment lever and urges the adjustment lever toward the base such that the stopper lever is in the skid-sliding mode.
  • the weight of the skier which acts on the adjustment lever, thus counteracts the spring force of the biasing spring.
  • the adjustment lever is relieved and the spring force of the biasing spring pulls or pushes the rod into a position in which the adjustment lever pivots the stopper member into the skis brake mode. This ensures that a ski on which the buttock device is mounted, without guidance by the skier can not slide unchecked along a slope, since the stopper lever is in the Skibremsmodus.

  • the operating element in the holding position of the heel lever does not block the rod, so that a pivoting of the stopper lever in the ski braking mode or in the Skigleitmodus is dependent on a load of the adjusting lever by a skier.
  • the skier can simultaneously activate or deactivate the stopper lever mechanism when adjusting the heel lever between the holding position and the passive position without much effort.

For example, if the heel lever is pushed from the hold position toward the passive position, for example because of a load on the heel area of the ski boot during a fall of the skier, the heel lever also presses against the hold-down. The hold-down in turn is held by the further spring force of the other biasing spring.
