A soleholder member constitutes a coupling link of a four-bar linkage, which is movable from its normal position against the force of a spring and which comprises levers that are pivoted to a carrying plate which constitutes or is pivoted to a baseplate to be secured to the ski. One of the pivot pins which connect the coupling link to the levers and which in the normal position of the toe iron are symmetrically disposed with respect to the longitudinal center line of the toe iron carries an arm which is capable of a limited pivotal movement and which in the normal position of the toe iron assumes an end position in which the free end of said arm overlaps and in one point disposed on the longitudinal center line of the toe iron contacts the free end of another arm, which is connected to the lever that carries the other pivot pin. The spring is held at one end on the carrying plate or on the coupling link and at its other end engages the first-mentioned arm. This arm is provided with a series of spring-connecting means, which are selectively connectable to the spring and which do not influence the initial stress of the spring. |
