Abstract
Abstract A safety ski binding with a rigid base plate arranged between the ski boot and the ski. The ski boot is detachably fastened by hand to the base plate. The base plate is permanently connected with the ski by means of two steel cables which are anchored inside of the base plate by springs so as to yield elastically in case of a fall of the skier.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
152 words
A safety ski binding comprising a rigid base plate arranged for detachable fastening to a ski boot, said base plate including two spaced release devices for establishing automatically releasable connections between the base plate and the ski, the automatic release being effected upon occurrence of an excessive force tending to separate said base plate and ski at the location of a release device, said release devices each including at least one guide roller mounted for movement along said base plate transversely of the roller axis, cable means fixed at one end to said base plate and passing over said guide roller and outwardly of said base plate for attachment to the ski, and spring means biasing said guide roller along its path of movement for applying tension to said cable means and permitting it to be drawn a distance from said base plate greater than said guide roller moves in response thereto.
Claim 2
Dependent Claim

A safety ski binding as claimed in claim 2, wherein said base plate comprises two superimposed shell halves providing inner recesses in which the guide roller, compression springs, and the larger portion of the cable means are disposed.
Claim 5
Dependent Claim
48 words
The safety ski binding as claimed in claim 3 wherein each shell half includes similar recesses, said recesses including longitudinal portions shaped to house each said compression spring with a slot left between said portions to provide a longitudinal guide for the bearing member for said guide roller.
Claim 6
Dependent Claim
50 words
A safety ski binding as claimed in claim 1, wherein said cable means pass out of said base plate through openings flaring outwardly with rounded edges and provided in the front and rear end faces of the base plate at a downward inclination of the ski from inside to outside.
