Abstract
Abstract A ski binding heel unit having a housing and a release lever pivotable relative to a ski base plate and each other. The release lever has an upwardly directed portion with a forwardly extending nose thereon engageable with a pair of faces on the housing. An adjustable compression spring between a rear housing wall and the upwardly directed portion urges the nose of the release lever into engagement with one of two abutment faces on the housing. A rearwardly extending portion is positioned beneath an opening in the housing for actuation of the ski binding.

Claim 3
Dependent Claim
23 words
A ski binding heel unit as defined in claim 1 wherein said housing has an opening therein adjacent said rearwardly extending lever arm.
Claim 4
Dependent Claim
45 words
A ski binding heel unit as defined in claim 1 wherein said two abutment faces include a cam between them forming a saw tooth outline which engages said nose in the manner of a cam when the heel unit is lowered into its operating position.
Claim 5
Dependent Claim
47 words
A ski binding heel unit as defined in claim 1 wherein an upper face of said abutment faces and said nose have a rounded configuration so as to form an overload release or safety release which is adjustable through adjustment of the preload of the biasing means.
Claim 6
Dependent Claim
47 words
A ski binding heel unit as defined in claim 1 wherein an upper face of said abutment faces and said nose have a slanted configuration so as to form an overload release or safety release which is adjustable through adjustment of the preload of the biasing means.
Claim 7
Dependent Claim
26 words
A ski binding heel unit as defined in claim 1 wherein said nose is in the form of a roller which rotates around a horizontal axis.
Claim 8
Dependent Claim
31 words
A ski binding heel unit as defined in claim 1 wherein said abutment faces form part of a plate which is attached to the rear side of a transverse housing wall.
Claim 9
Dependent Claim
60 words
A ski binding heel unit as defined in claim 1 wherein said biasing means is in the form of a compression spring and rests with one end against a pin shaped protrusion on the rear wall of the housing and with its other end against said release lever and being centered in a centering recess in said upwardly extending portion.
Claim 10
Dependent Claim
33 words
A ski binding heel unit as defined in claim 8 wherein said centering pin is part of a threaded adjustment screw which engages a threaded bore in the rear wall of the housing.
Claim 11
Dependent Claim
35 words
A ski binding heel unit as defined in claim 1 wherein said housing and said release lever are pivotable about a pair of pivoting pins, said pivot pins being retained in spaced upwardly extending ears.
Claim 12
Dependent Claim
60 words
A ski binding heel unit as defined in claim 1 wherein said base plate includes a lateral protrusion on each side, the heel unit further including two clamping profiles which engage the lateral protrusions from above, thereby adjustably clamping the heel unit onto the ski, matching faces of the lateral protrusions and of the clamping profiles including matching transverse serrations.
Claim 13
Dependent Claim
58 words
A ski binding heel as defined in claim 11 wherein said two clamping profiles are a one-piece plastic molding prior to initial assembly, the ends of the profiles being linked by connecting yokes with weakening notches at the connecting points, so that the connecting yokes can be broken off following assembly of the heel unit to the ski.
Claim 14
Dependent Claim
69 words
A ski binding heel unit as defined in claim 1 wherein said housing includes on its forward side a trip plate which extends beyond said base plate so as to reach under the heel of the ski boot, the heel unit further including an adjustable heel retaining cup engaging the rim of the heel from above and a threaded adjustment pin for the vertical adjustment of said retaining cup.
Claim 15
Dependent Claim
40 words
A ski binding heel unit as defined in claim 13 wherein said housing, release lever, base plate, heel retaining cup, and serrated clamping profiles of the heel unit, as well as the entire toe unit are manufactured of plastic material.
