Abstract
A ski binding consists of: a baseplate mounted on the ski; two arms articulated in relation to the baseplate, arranged symmetrically in relation to the longitudinal axis of the ski, and each comprising a retaining jaw; a resilient element actuating the jaws on the articulated arms through a transmitting element; in relation to the baseplate, the articulated arms rotate about a vertical axis and move longitudinally; the present binding has been designed for the express purpose of restricting the intensity of the frictional forces between parts moving in relation to each other.

A safety binding for a ski boot comprising:
- a baseplate adapted to be mounted to a ski;
- a supporting element integral with said boot;
- two arms pivotally mounted to said baseplate and being arranged symmetrically relative to the longitudinal axis of said ski;
- each arm including a retaining jaw extending over the plane of said baseplate and cooperating with a lateral edge of said supporting element;
- a resilient element mounted on said baseplate;
- a movement transmitting element inter-connecting said resilient element and said jaws of said arms;
- said resilient element acting through said movement transmitting element to apply said jaws against said supporting element and to allow a safety release of said jaws from said supporting element in the event of an abnormally high load applied by said boot;
- said arms rotating about a vertical axis and simultaneously moving longitudinally relative to said baseplate to allow clamping or release of said jaws;
- said transmitting element moving longitudinally in relation to the baseplate,
- each articulated arm:
- rotating about a vertical axis which is fixed in relation to the transmitting element, and
- pivoting slidingly about a supporting point which is fixed in relation to the baseplate and comprising a ramp upon which said supporting slides;
- said ramp being located between boot-retaining jaw and said vertical axis of rotation fixed in relation to the transmitting element;
- said resilient element being in the form of a spring arranged along the longitudinal axis of the ski:
- one end of said spring bearing against a shoulder integral with the baseplate, and
- the other end of said spring bearing against a shoulder integral with said transmitting element.

- a baseplate adapted to be mounted to a ski;
- a supporting element integral with said boot;
- two arms pivotally mounted to said baseplate and being arranged symmetrically relative to the longitudinal axis of said ski;
- each arm including a retaining jaw extending over the plane of said baseplate and cooperating with a lateral edge of said supporting element;
- a resilient element mounted on said baseplate;
- a movement transmitting element inter-connecting said resilient element and said jaws of said arms;
- said resilient element acting through said movement transmitting element to apply said jaws against said supporting element and to allow a safety release of said jaws from said supporting element in the event of an abnormally high load applied by said boot;
- said arms rotating about a vertical axis and simultaneously moving longitudinally relative to said baseplate to allow clamping or release of said jaws;
- said transmitting element moving longitudinally in relation to the baseplate,
- each articulated arm:
- rotating about a vertical axis which is fixed in relation to the transmitting element, and
- pivoting slidingly about a support point which is fixed in relation to the baseplate and comprising a ramp upon which said supporting point slides;
- said ramp being located between the boot-retaining jaw and said vertical axis of rotation fixed in relation to the transmitting element;
- said transmitting element being caused to move longitudinally by the resilient element, in a direction running from the jaw to said supporting point;
- said binding further comprising a voluntary-ski-removal element in the form of a lever which is hinged in relation to the baseplate and which cooperates with a ramp integral with the transmitting element, said lever causing said transmitting element to move longitudinally in a direction running from said point of support towards the jaw, and being adapted to move between two positions:
- a first position in which:
- the transmitting element is locked in relation to the baseplate,
- the articulated arms are free to pivot and move the jaws away from the boot,
- a second position in which:
- the transmitting element is unlocked and transmits, to the articulated arms and jaws, the force applied by the resilient element.

In combination, a safety binding and a ski boot comprising:
- a baseplate adapted to be mounted to a ski;
- a supporting element integral with said boot;
- two arms pivotally mounted to said baseplate and being arranged symmetrically relative to the longitudinal axis of said ski when mounted thereon;
- each arm including a retaining jaw extending over the plane of said baseplate and cooperating with a lateral edge of said supporting element;
- a resilient element mounted on said baseplate;
- a movement transmitting element inter-connecting said resilient element and said jaws of said arms;

- said arms rotating about a vertical axis and simultaneously moving longitudinally relative to said baseplate to allow clamping or release of said jaws;
- one end of said boot being provided with a recess which, after release, allows the retaining jaws to pass under the sole of the boot, when said boot pivots in response to a lateral load.
