Abstract
Abstract A ski brake is provided with two braking arms pivotally mounted in bearings disposed transversely with respect to the ski. The braking arms are downwardly inclined towards the interior of the ski and joined together by means of a resilient stirrup-piece located above the ski and capable of undergoing resilient flexural deformation in its own plane. The stirrup-piece is connected to the braking arms by means of pivot-pins in the form of rivets, the axes of which are located at right angles to the plane of the stirrup-piece.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
86 words
A ski brake comprising two braking arms which are pivotally mounted in bearings disposed transversely with respect to the ski but the axes of which are downwardly inclined towards the interior of the ski, said arms being connected together by means of a resilient stirrup-piece located above the ski and capable of undergoing resilient deformation under bending stress in its own plane, wherein said stirrup-piece is pivotally connected to said braking arms by means of articulation, whose axes are perpendicular to the plane of said stirrup-piece.
Claim 2
Dependent Claim
86 words
A ski brake comprising two braking arms which are pivotally mounted in bearings disposed transversely with respect to the ski but the axes of which are downwardly inclined towards the interior of the ski, said arms being connected together by means of a resilient stirrup-piece located above the ski and capable of undergoing resilient deformation under bending stress in its own plane, wherein said stirrup-piece is pivotally connected to said braking arms by means of articulation, whose axes are perpendicular to the plane of said stirrup-piece.
Claim 3
Dependent Claim
49 words
A ski brake according to claim 1, wherein the stirrup-piece has the shape of a C pivotally connected to the braking arms by means of said articulation, and consequently undergoes deformation in the direction of opening when the braking arms are displaced in pivotal motion to an inactive position.
Claim 4
Dependent Claim
56 words
A ski brake according to claim 1, wherein the stirrup-piece has the shape of a U pivotally connected to the braking arms by means of said articulation, located below the axis of the bearings and consequently undergoes deformation in the direction of closure when the braking arms are displaced in pivotal motion to an inactive position.
Claim 5
Dependent Claim
15 words
A ski brake according to claim 1, wherein the stirrup-piece is made of spring-steel wire.
Claim 6
Dependent Claim
16 words
A ski brake according to claim 1, wherein the stirrup-piece is made of molded plastic material.
Claim 7
Dependent Claim
14 words
A ski brake according to claim 1, wherein the articulations are constituted by rivets.
Claim 8
Dependent Claim
15 words
A ski brake according to claim 5, wherein said plastic material is a thermoplastic resin.
