It also includes a connection between the sensor element and stiffening blade in order to transmit to the blade, in the form of at least one longitudinally or horizontally oriented force in the direction of either one and/or the other of its ends, at least a portion of the downward vertical thrust of the boot captured by sensor element.

Abstract: The invention relates to an interface device between a ski and element for retaining a boot on the ski. The device includes two stops intended to be connected to the ski toward the front and rear, respectively, of the central portion of the base of the ski, and a linking leg forming a stiffener between these two stops. The linking leg includes at least two levers, which are connected by at least one linkage forming a central pivotable connection. One of the bearing plates of the boot is vertically movable and transmits the vertical stresses from the boot to one of the levers, and an elastic restoring mechanism exerts an upward restoring force against one of the levers that is of sufficient intensity to keep the central pivotable connection of the two levers suspended when the boot is present. Preferably, the linkage between the levers is disengageable.

The device includes two binding elements, a mobile sensor, a return rocking device, and an element affixed to the ski. The rocking device is arranged to transform a vertical bias exerted on the sensor into a traction bias exerted on the element affixed to the ski. In reaction, a traction bias of the same type can be transmitted towards the rear of the ski.
