Abstract
Abstract A heel portion of a ski binding comprises a casing which pivotably supports a latch lever for movement about a horizontal axis and a release lever for pivotal movement about a second horizontal axis. The release lever carries a heel retainer and a latching bolt which engages with a latching surface on the latch lever. A release spring is pivotably carried on the casing and acts on the latch lever to oppose release of the bolt from the latching surface, and the spring carries a displaceable element at its front end which is engaged with the latch lever for transmitting the force of the spring to the latch lever. The displaceable element is displaceable along the latch lever upon pivotal movement of the spring between a first position remote from the pivot axis of the latch lever on the casing and a second position closer to the latter axis, such that in the second position the opposite of the spring to release of the bolt from the latching surface is substantially less than in the first position.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
191 words
A heel portion of a ski binding comprising a heel retainer having operative and release positions and being selectively movable therebetween, a casing, a latch lever connected to said casing for pivotal movement about a horizontal axis, a release lever carrying said retainer and mounted on said casing for pivotal movement about a second horizontal axis between the operative and release positions for said heel retainer, latching means between said latch lever and said release lever for releasable latching therebetween, a release spring pivotably carried on said casing and acting on said latch lever to oppose release of said latching means, a displaceable element carried by said spring and engaged with the latch lever for transmitting the force of the spring to said latch lever, said displaceable element being displaceable along the latch lever upon pivotal movement of the spring between a first position remote from the pivot axis of the latch lever on the casing and a second position closer to the latter said axis such that in said second position the opposition of the spring to release of the latch means is substantially less than in the first position.
Claim 2
Dependent Claim
191 words
A heel portion of a ski binding comprising a heel retainer having operative and release positions and being selectively movable therebetween, a casing, a latch lever connected to said casing for pivotal movement about a horizontal axis, a release lever carrying said retainer and mounted on said casing for pivotal movement about a second horizontal axis between the operative and release positions for said heel retainer, latching means between said latch lever and said release lever for releasable latching therebetween, a release spring pivotably carried on said casing and acting on said latch lever to oppose release of said latching means, a displaceable element carried by said spring and engaged with the latch lever for transmitting the force of the spring to said latch lever, said displaceable element being displaceable along the latch lever upon pivotal movement of the spring between a first position remote from the pivot axis of the latch lever on the casing and a second position closer to the latter said axis such that in said second position the opposition of the spring to release of the latch means is substantially less than in the first position.
Claim 3
Dependent Claim
31 words
A heel portion as claimed in claim 1 wherein said latch means comprises a bolt on said release lever, and a latch surface on said latch lever for receiving said bolt.
Claim 4
Dependent Claim
30 words
A heel portion as claimed in claim 1 wherein said latch lever has at least one guiding surface against which the displaceable element is in contact for guided displacement therealong.
Claim 5
Dependent Claim
24 words
A heel portion as claimed in claim 1 wherein said displaceable element includes lateral boltlike projections guidably supported for displacement by said latch lever.
Claim 6
Dependent Claim
26 words
A heel portion as claimed in claim 1 comprising a cover connected to said casing for pivotable movement about a horizontal axis and carrying said spring.
Claim 7
Dependent Claim
26 words
A heel portion as claimed in claim 5 wherein the axis of rotation of the cover coincides with the axis of rotation of the release lever.
Claim 8
Dependent Claim
33 words
A heel portion as claimed in claim 5 wherein said spring has a forward end on which the displaceable element is supported, the rearward end of the spring being connected to said cover.
Claim 9
Dependent Claim
20 words
A heel portion as claimed in claim 7 comprising means on said cover for adjusting the tension in the spring.
