A safety binding for snowboards has a base plate (1) on which the snowboarder's boot is fastened. This base plate (1) is fixed in its turning position by a spring plunger (8) and a stop pin (7), but can be turned out of this position when the torque acting on it exceeds a value preset by the initial tension of the spring (10) of the spring plunger (8). The base plate (1) is rigidly connected with the snowboard by means of a turning plate (2) and is not detached from the snowboard even in the case of a "turning release".

[ What is claimed is:] [1.] A safety binding for attachment to a snowboard, said safety binding comprising:a base plate having a circular central opening therethrough and having an upper surface;a circular turning plate positioned within the central opening of said base plate for attachment to the snowboard, said turning plate having a radially projecting edge that overlaps said upper surface of said base plate to prevent translation of said base plate relative to said turning plate and the snowboard while permitting rotation of said base plate relative to said turning plate and the snowboard; andmeans for releasably locking said base plate against rotation relative to said turning plate and the snowboard, said means for releasably locking comprising:a spring fixed to said base plate;a cylindrical bolt positioned within the central opening of said base plate so that said turning plate is positioned radially between said base plate and said bolt, said bolt being fixed relative to said turning plate and the snowboard in operation;a stop recess formed in the exterior surface of said bolt and fixed against rotation relative to said turning plate and the snowboard; anda stop pin fixed to said base plate, positioned adjacent an end of said spring, and releasably engagable in said stop recess;whereby said means for releasably locking releases said base plate for rotation relative to said turning plate and the snowboard when a predetermined torque about an axis perpendicular to the snowboard is exceeded.
