Abstract: A safety ski binding includes a sole holder which is pivotally supported on a base member for movement upwardly about a transversely extending axle relative to the base member. The sole holder in the position of use is held thereat by a locking spring which acts onto a locking mechanism also supported on the base member. A hand lever is pivotally secured to the base member for movement about a second transversely extending axle, and through compression of the locking spring overcomes the spring loading of the locking mechanism. Thus, the sole holder can be swung upwardly force-free. The locking mechanism includes a first locking rocker arm which is pivotally supported for movement about the second axle and engages the sole holder and a second locking spring. The second locking rocker arm is also supported on the base member. The hand lever engages the first locking rocker arm so that upon a manual manipulation thereof, the locking spring will be compressed until the sole holder can be freely swung upwardly.
