Abstract: The heel bail assembly incorporates tension members, such as rods, and compression springs, the springs being enclosed in casings. Each of two side tension members extend from the toe assembly of a ski harness into a casing. A U-shaped tension member extends from one casing around the ski boot heel to the other casing. Threaded connections of the side tension members to the casings enable adjustment of the length of the bail assembly.

Abstract: There are two assemblies in the binding, a harness assembly and an attachment assembly. The harness assembly attaches to a ski boot and has a toe fitting which fits over the toe of the boot and has a flat metal plate contacting the toe portion of the sole of the boot. Four sharp pointed posts extend downward from the plate. Each post has a groove near its base, perpendicular to the axis of the post. The attachment assembly attaches to the ski and has latch bars which engage the grooves in the posts to attach the attachment assembly and ski to the harness and ski boot. One latch bar is spring loaded toward the other and as the posts are inserted onto the attachment assembly the spring loaded bar is moved to allow the posts to pass. When the posts are fully inserted the spring loaded bar moves to capture the posts. There is a lever operated cam at the forward end of the attachment assembly which is used to separate the latch bars to enable detaching the ski from the harness.
