Abstract
Abstract A connection between the ski and the skiing boot is provided for by a separate soleplate. A plate-holding device engages the soleplate behind the heel of the boot. An abutment for the soleplate is mounted on the ski. The plate-holding device normally urges the soleplate against the abutment and releases the same in response to an overload acting in a vertical and/or horizontal direction. The abutment consists of a lever, which is pivoted to the ski on an axis which is transverse to the longitudinal direction of the ski. Said lever has a free end portion extending toward the rear end of the ski. A disc is provided on the underside of the soleplate and is adapted to be approximately coaxial to the tibia of the skier and bears on the free end portion of the lever. At least two bearing blocks are secured to the ski below the soleplate and support the soleplate before and behind the disc. The plate-holding device comprises a known, spring-loaded detent member, which engages a wedge-shaped notch at the rear end of the soleplate. The apex of said notch is rearwardly and downwardly inclined.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
175 words
A safety ski binding comprising a soleplate adapted to receive the skiing boot of a skier, said soleplate having a wedge-shaped notch associated with the rear end of the soleplate, an abutment mountEd on the ski comprising a lever having one end pivoted to the ski on an axis which is transverse to the longitudinal direction of the ski and having another end which is unattached to the ski and extends toward the rear of the ski, a disc mounted on the underside of the soleplate and adapted to be approximately coaxial to the tibia of the skier, bearing means mounted on the ski below the soleplate such that the soleplate can bear on the bearing means in front of and behind the disc, and means adapted to engage the rear of the soleplate and to urge the disc against the unattached end of the lever and to release the soleplate in response to an overload force, said means comprising detent means and spring means adapted to urge said detent means against the wedge-shaped notch.
Claim 2
Dependent Claim
175 words
A safety ski binding comprising a soleplate adapted to receive the skiing boot of a skier, said soleplate having a wedge-shaped notch associated with the rear end of the soleplate, an abutment mountEd on the ski comprising a lever having one end pivoted to the ski on an axis which is transverse to the longitudinal direction of the ski and having another end which is unattached to the ski and extends toward the rear of the ski, a disc mounted on the underside of the soleplate and adapted to be approximately coaxial to the tibia of the skier, bearing means mounted on the ski below the soleplate such that the soleplate can bear on the bearing means in front of and behind the disc, and means adapted to engage the rear of the soleplate and to urge the disc against the unattached end of the lever and to release the soleplate in response to an overload force, said means comprising detent means and spring means adapted to urge said detent means against the wedge-shaped notch.
Claim 3
Dependent Claim
33 words
The safety ski binding of claim 1 in which the disc is round and the unattached end of the lever has a recess which normally engages part of the periphery of the disc.
Claim 4
Dependent Claim
73 words
The safety ski binding of claim 2 and further comprising a centering plate mounted on the ski on the opposite side of the disc from the lever and in which the centering plate has a recess facing the disc having part of the arc of a circle having the same radius as the radius of the disc and in which the recess of the centering plate embraces the disc and is spaced therefrom.
Claim 5
Dependent Claim
32 words
The safety ski binding of claim 1 in which the bearing means in front of the disc compriSe bearing blocks sapced equal distances apart from the axis of rotation of the soleplate.
Claim 6
Dependent Claim
25 words
The safety ski binding of claim 1 in which the wedge-shaped notch has a wedge angle which is continuously decreasing in the downward vertical direction.
Claim 7
Dependent Claim
93 words
A safety ski binding of claim 3 and further comprising retaining means providing an additional connection between the ski and the soleplate, said retaining means comprising two elastic strips positioned below the soleplate and on both sides of the disc and extending parallel to the longitudinal direction of the ski, each of said strips having one end mounted on the ski and the other end mounted on the underside of the soleplate in such a manner that the end of the strip which is nearer to the disc is mounted on the ski.
Claim 8
Dependent Claim
44 words
The safety ski binding of claim 6 in which the ends of the elastic strips are articulately connected to the ski and to the soleplate and in which the centering plate serves as one of the means for securing the strip to the ski.
