A safety ski binding comprises a footplate and a tie rod which is mounted on said footplate and is adapted to be displaceable against spring force in the axis of symmetry of the footplate. This axis of symmetry extends in the longitudinal direction of the ski when the binding is in position for a downhill run. Said tie rod is adapted to be held in position by a tightener. Two pairs of rollers are carried by the tie rod and the footplate, respectively. The axles of said rollers extend transversely to the longitudinal axis of the tie rod and parallel to the plate and are secured to the tie rod and the plate, respectively. Said tie rod has a portion which extends within a guide and is provided adjacent to the tightener with an upwardly directed release nose. The boot which is associated with the binding is provided at the forward and near edges of its heel with bearing surfaces for the rollers and is provided preferably in the tread face of the heel with a groove which receives the guide when the binding is in position for a downhill run. Said footplate is pivotally movable about a pivot which is mounted on the baseplate.
A ski binding comprising a baseplate adapted to be secured to a ski, a footplate guided by said baseplate, a spring-loaded tightener, and forward and rear rolling means for gripping a heel of a boot, said footplate having mounting means for displaceably mounting a rod, which extends in the skiing direction and is mounted by said mounting means so as to be adjustable in said direction, said rod having a cam face which is oblique in the skiing direction and which cooperates with means carried by said tightener so as to open the same when the ski binding is under an excessively high load in the skiing direction, said footplate being rotatably mounted on a pin which is carried by said baseplate at that end thereof which is nearer to the tip of the ski, said baseplate having guiding surfaces which cooperate during a rotation of said footplate about said pin with means carried by said rod so as to longitudinally displace the same, said forward rolling means being carried by said rod, said rear rolling means being carried by said footplate.
