Abstract
Abstract An expanding member is adapted to be screw-connected to the ski and serves to expand two pantograph arms having forward end portions pivoted to a coupling link, before the expanding member and rear end portions, which are pulled toward each other behind the expanding member by a spring. Elements for guiding and retaining the pantograph arms are adapted to be screw-connected to the ski and prevent a displacement of the pantograph in the longitudinal direction of the ski but enable a pivotal movement of the pantograph about the expanding member.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
122 words
A safety ski binding comprising a noncircular expanding member adapted to be connected to a ski; said expanding member serving to expand two pantograph arms; said pantograph arms having forward end portions pivoted to a coupling link in front of the expanding member and rear end portions which are pulled toward each other behind the expanding member by a spring, and guiding and retaining elements mounted to said ski; said guiding and retaining elements being arranged in front of said pantograph arms and behind said pantograph arms to allow the ends of said pantograph arms to rest so that the pantograph arms are secured from displacement in the longitudinal direction of a ski but are permitted to pivot around the expanding member.
Claim 2
Dependent Claim
122 words
A safety ski binding comprising a noncircular expanding member adapted to be connected to a ski; said expanding member serving to expand two pantograph arms; said pantograph arms having forward end portions pivoted to a coupling link in front of the expanding member and rear end portions which are pulled toward each other behind the expanding member by a spring, and guiding and retaining elements mounted to said ski; said guiding and retaining elements being arranged in front of said pantograph arms and behind said pantograph arms to allow the ends of said pantograph arms to rest so that the pantograph arms are secured from displacement in the longitudinal direction of a ski but are permitted to pivot around the expanding member.
Claim 3
Dependent Claim
43 words
A safety ski binding according to claim 1, wherein the coupling link carries a mouthlike abutment for the toe portion of the skiing boot and the abutment has an angled upper end portion for engaging the edge portion of the sole from above.
Claim 4
Dependent Claim
36 words
A safety ski binding according to claim 1, wherein the rear end portions of the pantograph arms carry a baseplate which serves to hold a holding-down device that is under the action of a spring element.
Claim 5
Dependent Claim
26 words
A safety ski binding according to claim 3, wherein the holding-down device consists of a known heel-holding device which releases the skiing boot under an overload.
Claim 6
Dependent Claim
28 words
A safety ski binding according to claim 1, wherein each pantograph arm is provided on its outside with downpull hooks and the coupling link carries a cable tightener.
Claim 7
Dependent Claim
36 words
A safety ski binding according to claim 1, wherein the abutment for the toe portion of the skiing boot is pivoted on a horizontal axis member which extends transversely to the longitudinal direction of the ski.
Claim 8
Dependent Claim
34 words
A safety ski binding according to claim 6, wherein a soleplate extends from the lower end of the abutment for the toe portion of the skiing boot and is provided with a heel-holding device.
Claim 9
Dependent Claim
37 words
A safety ski binding according to claim 7, wherein the soleplate extends behind the skiing boot and is pivoted at its free end to the holding-down device and carries a heel-holding device which is only arbitrarily releasable.
