  • the heel-engaging projections and the main body are each elastically biased into a normal position, in which a heel portion of the shoe is fixed in the running position on the ski.
  • the movement of the heel-engaging projections away from each other against an elastic biasing force permits frontal deployment, i. releasing or releasing the ski boot upon application of a torque about a ski axis (Y-axis) when this torque exceeds a My-release torque.
  • the pivoting movement of the main body against the elastic force of the second tightening direction allows a side release, i. releasing or releasing the ski boot from the heel unit upon application of a torque about a vertical axis (Z axis) greater than an Mz release torque.
  • the object of the invention is to provide a heel unit for a binding, which allows both My-triggering and Mz-triggering, but which can be produced with reduced design complexity or reduced size / weight.
  • the invention proposes a heel unit of the generic type, which according to the invention has an elastic element which provides both clamping force for the first clamping device and clamping force for the second clamping device.
  • the invention thus provides an elastic element with double function, which on the one hand provides clamping force for the frontal release and on the other hand clamping force for the side release, so that the provision of separate elastic elements as well as the support and coupling separate elastic elements for biasing the heel-engaging projections on the one hand and the biasing of the main body on the other hand can be dispensed with.
  • the frontal release mechanism and the side release mechanism can share an important functional part, namely a force source for the deployment force.
  • a heel unit of the invention can be manufactured with less design effort and thus smaller or lighter.
  • the first tensioning device comprises a first power transmission arrangement, which transfers tensioning force from the elastic element to the at least one of the heel engagement projections, preferably to both heel engagement projections
  • the second tensioning device comprises a second power transmission arrangement, which tensioning force transmits from the elastic member to the main body.
  • the elastic member may include a fixed portion and a movable portion between which acts the elastic biasing force of the elastic member.
  • the specified section can be directly fixed to the main body, creating a particularly simple construction.
  • the fixed portion may be supported on a support element fixed in an adjustable position relative to the main body, which may have the advantage that by adjusting the position of the support element, a biasing force of the elastic element, in particular for setting a triggering torque, can be changed.
  • it can be adjusted advantageously by only one adjustment movement of the support member of the common elastic element, a release torque for both side release as well as for frontal release simultaneously.
  • the support member may be, for example, an adjustable spring stop.
  • a movable portion of the elastic member may be connected to a control body so that the control body can move relative to the main body with or against the elastic force of the elastic member.
  • the control body can then be manufactured as part of the first or / and the second power transmission arrangement as a low-cost component.
  • a common control body is part of both the first power transmission arrangement and the second power transmission arrangement, so that the control body also has a double function both as part of the front release mechanism and as part of the side release mechanism, and further simplification of the device becomes possible.
  • the first power transmission assembly may include a first camming transfer between the control body and the heel engagement projections and the second power transmission assembly may comprise a second camming transmission between the control body and the base body.
  • a power transmission arrangement based on a cam transmission provides a simple and highly effective way of transmitting power and motion.
  • a control curve transmission is understood to mean a transmission between a first element and a second element, in which the two elements slide or roll against one another and in which by appropriate shaping of the contours of the two elements and / or by restricting the freedom of movement of the elements Movement of the one element can be implemented in a predetermined movement of the other element.
  • the transmission can take place, in particular, with a change in the direction of movement, with a change in the speed of movement and / or under an increase in power or a loss of power.
  • Cam transmissions are known to those skilled in the art in the form of cam transmissions, wedge surface transfers or the like.
  • the control cams used can have a curved or straight course and can be continuous or unsteady.
  • first and / or the second control cam transmission comprises a wedge surface and a wedge opposing surface sliding off on the wedge surface, then a substantially rectilinear relative movement between the two Both elements of the control curve transmission can be achieved and a manufacturing technology simple power transmission arrangement can be realized.

  • the cam follower may in particular be designed to simplify the production as a portion of the control body, ie be integrally connected to the control body, or may be attached to the control body, for example, to make the cam follower as a wear component interchangeable.
  • a pivotal movement of the main body in a direction from the normal position to the side release position (to the left or to the right) is then opposed to an elastic clamping force of the elastic element, while a pivotal movement in a direction from a side release position to the normal position is supported by the elastic resilience of the elastic member.
  • control cam may preferably be formed in a recess at an upper end of the pin, so that the control cam can be produced by simple machining or by simple shaping manufacturing process.

  • Such pins with wedge elements are, for example, from the AT 402 020 B known there and allow a simple power transmission between a jig and the pins.
  • the use of a wedge surface and a counter wedge surface is relatively low maintenance and works reliably even in adverse conditions.
