Abstract

Abstract Safety ski binding includes a rigid base plate member disposable between a sole member of a ski boot and a ski member. A locking device manually releasably connects the base plate member to one of the other members, and other locking devices automatically releasably connects the base plate member to the other of the other members. The other locking devices include respective spring-loaded locking elements mutually opposing one another in longitudinal direction of the ski member. The locking devices are received in one of the members, the locking members overlying a reduced part of the one member wherein both locking devices are received. Coupling elements cooperating with the locking elements at the reduced part of the one member extend substantially perpendicularly from another of the members and have respective surfaces facing toward the locking elements. The surfaces extend transversely to the longitudinal direction of the ski member and are curved with respect to a common center of curvature.
