Abstract
Abstract A brake mechanism adapted to be secured to a ski for braking the ski, comprises at least one brake element movable, upon release of the boot from the ski binding, from a position above the running surface of the ski automatically downwardly into a ski braking position, to thereby engage with the snow for the purpose of exerting a braking force upon the ski. A retaining element actuatable upon inserting the boot into the ski binding retains the braking element in its preparatory braking position, so that upon release of such retaining element the braking element moves from its preparatory braking position into its actual ski braking position. A first locking-pawl arrangement serves to retain the braking element in a locked position for convenient transport and storage of the ski, and a second locking-pawl arrangement serves to retain such braking element in its preparatory braking position, this retaining element cooperating with said first locking-pawl arrangement and said second locking-pawl arrangement such that actuation of said retaining element causes release of the locked position of said braking element and transfer thereof into its preparatory braking position against a spring force effective at said retaining element.
