## Abstract

The heel piece of a safety binding for holding a boot on a ski, comprises a tubular binding body which is open at its two ends, is rigidly linked to a sole grip (1a) and is articulated about a transverse cam forming part of a stirrup piece (3) which is articulated onto a pivoting plate (4) joined to the ski, this body containing at least one spring which works in compression between a piston bearing on the cam, and a stop secured to a setting screw. The setting screw bears axially, by its head, against a bearing zone of the binding body, and the stop consists of a nut mounted on the setting screw, the screw, with its stop, the spring and the piston being mounted in the body through the end corresponding to the sole grip.

## Claims

### Claim 1

A heel piece of a safety binding for holding a boot on a ski, comprising a tubular binding body (1) having an upper opening adjacent an upper end, the upper opening having an inner bearing zone (1b) and a lower, unobstructed opening adjacent a lower end having an integral sole grip (1a), and which is articulated about a transverse cam (10) forming part of a stirrup piece (2, 3, 10) articulated about a horizontal axis onto a plate (4) mounted so as to pivot on the ski about a substantially vertical axis, this body containing at least one spring (5) which works in compression between a piston (6) bearing on the cam, and a stop secured to a setting screw (8) having a head, wherein the setting screw (8) bears axially, by its head, against the bearing zone (1b) of the binding body, and wherein the stop consists of a nut (7) mounted on the setting screw (8), the nut having a visual indicator member associated therewith extending through an opening in the tubular binding body, wherein the screw, with its stop, the spring and the piston being mounted in the body (1) through the lower end corresponding to the sole grip.

### Claim 2 (depends on 1)

The heel piece as claimed in claim 1, which comprises a washer (9) with low coefficient of friction between the setting screw (8) and the bearing zone which forms part of the body and on which the screw bears.

### Claim 3 (depends on 1)

The heel piece as claimed in claim 1, wherein the head of the setting screw (8) is provided with a collar (8a) by which the setting screw bears on the bearing zone of the body.
