Abstract
Abstract Releasable heel retainer for a ski binding that can be optionally set for starts or cross-country runs and which is guided on a stationary base portion for rocking movement and is also displaceable relative thereto, and which comprises a base, an intermediate housing supporting an outer housing that carries a sole-holding member, where the connection between the intermediate housing and the base portion is defined by forward and rearward joints that extend horizontally and transversely of the binding and which can be raised from the base by means that optionally free either the rear joint while latching the front joint or vice versa.

Claim 3
Dependent Claim
72 words
Heel retainer in accordance with claim 1, where said base has upwardly extending cheeks and said front and rear linkages comprise front and rear slots in said cheeks and pivot pins extending from said intermediate housing into said slots, and said means for latching and freeing said front and rear linkages comprising a slide member having sliding engagement with said cheeks and alternately movable to free said front or said rear linkages.
Claim 4
Dependent Claim
24 words
Heel retainer in accordance with claim 2, where said front slots extend generally vertically upwardly and said rear slots are inclined and extend rearwardly.
Claim 5
Dependent Claim
86 words
Heel retainer in accordance with claim 3, comprising toggle means disposed in the forward end of said housing having one arm pivotally connected at one end to said base and another arm having a bore, arcuate upwardly extending guiding slots in said cheeks proximate the forward end of said base and a guide pin extending from said intermediate housing into said slots and said bore, and a spring biased at its rearward end against said intermediate housing and at its forward end against said toggle meaNs.
Claim 6
Dependent Claim
41 words
Heel retainer in accordance with claim 4, where said intermediate housing has horizontally extending arcuate slots proximate said upwardly extending slots in said cheeks and said guide pin extends through said arcuate slots in said cheeks and in said intermediate housing.
Claim 7

Heel retainer in accordance with claim 5, where said base, said intermediate housing and said outer housing are generally box-shaped and have elongated sidewalls, said intermediate housing fits over the cheeks of said base and said outer housing fits over said intermediate housing.
Claim 8
Dependent Claim
51 words
Heel retainer in accordance with claim 7 including aligned bores in the upper rearward portions of said outer and said intermediate housing and a pivot pin defining a pivot axis extending through said bores, permitting pivotal movement of said housings relative to one another to establish the setting for cross-country runs.
Claim 9
Dependent Claim
25 words
Heel retainer in accordance with claim 7, where said pivot axis is defined by said rearward linkage including said inclined slot and said pivot pin.
Claim 10
Dependent Claim
28 words
Heel retainer in accordance with claim 8, where said intermediate housing is pivotable about said front linkage relative to said base to establish the position for cross-country runs.
Claim 11
