ABSTRACT:
FIELD OF THE INVENTION
The present invention relates to a heel piece of a safety binding for a ski boot, comprising a sole grip body which is mounted on a stirrup piece articulated to a plate which is in turn mounted so as to pivot on a base mounted and immobilized on a rail which is fixed to the ski.
PRIOR ART
A heel piece of this type has been marketed by the applicant under the brand LOOK
37
. Apart from the way in which the base is mounted on a rail, this heel piece is produced as described in patent CH 397 500.
This heel piece is intended to interact with a front binding, or toe piece, associated with a ski brake which can be raised by the pressure exerted by the boot on a pedal articulated to the arms of the brake. The position of the brake close to the front toe piece is unfavourable, because it tends to hinder insertion of the front end of the boot, in particular the sole, under the jaw of the front toe piece. It would therefore be preferable to arrange the brake close to the heel piece, as is the case in other types of bindings.
It would furthermore be appropriate for the position of the brake relative to the position of the pivoting plate not to vary as the base is moved on the rail, for adjusting the length of the binding.
SUMMARY OF THE INVENTION
To this end, the heel piece according to the invention is one which is equipped with a ski brake arranged in front of the pivoting plate, this brake being mounted on the base and articulated about an articulation axis that is transverse relative to the base and can be raised by the pressure exerted by the boot.
The distance between the pivot axis of the pivoting plate and the articulation axis of the brake is furthermore less than 70 mm, and preferably less than 20 mm, so that the brake is always actuated by the pressure of the heel region of the boot. This is desirable not only because of the optimum pressure exerted by the boot, but also because of the fact that the lower face of the sole of the boot, in front of the heel, often does not have enough area to actuate the pedal of the brake.
In the heel piece according to the prior art, the diameter of the pivot of the pivoting plate is such that the maximum distance of 70 mm cannot be adhered to. In order to achieve this maximum distance, it is possible to reduce the diameter of the pivot, but the forces on the latter and the play in the vertical planes increase rapidly as the diameter of the pivot decreases. Controlling these parameters properly leads to extra cost.
In order to solve this problem, in a preferred embodiment of the invention, the plate is pivotably mounted on the base through the mutual engagement and interaction of at least one rib in the form of an arc of a circle in a cutout in the form of an arc of a circle, these circle arcs being located between the pivot axis of the plate and the rear of the base.
According to a particular embodiment of the invention, the cutout in the form of an arc of a circle is formed in the pivoting plate, and the base has at least two concentric ribs interacting with each of the sides, in the form of an arc of a circle, respectively of the cutout.
