<p>This heel hold-down device for resiliently and releasably retaining the heel of a ski boot in a position of engagement with the ski surface comprises a resilient mechanism housed within the base member of the device and comprising a coil compression spring acting upon a transverse rotary shaft carrying at either ends eccentric trunnions engaging cam elements provided on said pivoting jaw or on the supporting bracket thereof, the contour of said cam elements being such that when said shaft is locked in its operative position by said spring said gripping jaw is also retained in its normal, lower position, the upward movement of said jaw causing the rotation of said transverse rotary shaft about its axis against the resistance of the spring.</p> |
