Abstract
A ski brake mounted on a ski and retained normally in a retracted position. When the skier's boot becomes separated from the binding on the ski in a casual manner, such as during ascent on a chairlift, a strap joining the skier's boot and the ski brake permits the ski to remain connected to the skier, although in a dangling condition. However, should the skier's boot become separated from the binding in an abrupt manner, as when skiing, the strap releases a retention mechanism holding the brake in a first or retracted position. Thereupon, the strap is completely separated from the brake and the brake is rapidly moved by a spring into a second position such that a brake shoe extends below a lower surface of the ski for engaging ice, snow, and the like. The brake shoe has a roughened outer surface as a further aid in impeding advancement of the runaway ski. Whenever convenient to the skier, a release mechanism on the strap can be operated to disconnect the strap from the boot.
