Abstract
Abstract An automatic brake for skis has a mounting for securing on the upper surface of the ski, for example by screws. A stirrup comprises a cross-member and two parallel arms disposed respectively one at each end of the cross-member. The stirrup is connected to the mounting by pivot means which permit movement of the stirrup about an axis parallel to the cross-member. Springloading is coupled to the mounting and to the stirrup to urge the stirrup into a first end position in which the parallel arms are normal to the plane of the mounting. The stirrup can be held in another end position, with the arms parallel to the ski, by the user''s foot.
