Abstract: A safety ski binding for releasably securing a ski boot on a ski includes a bearing block adapted to be supported on the ski, a stepping member supported on the bearing block for pivotal movement about a horizontal axis which extends transversely of the ski, and a sole holder adapted to engage a sole of the ski boot and supported on the sole holder for generally vertical movement relative thereto. A spring urges the sole holder downwardly relative to the support member, and an electrically controlled locking mechanism is adapted to releasably maintain the stepping member in a first position. An electrical switch of the locking mechanism closes when the sole holder has moved upwardly a predetermined distance relative to the stepping member and thereby causes the locking mechanism to release the stepping member for pivotal movement about the horizontal axis.
