Tibia support device for skier

Abstract

A retaining strap encircles the leg of the skier and keeps the tibia in contact with a support surface in the form of a padded cast, which is fixed to a deformable component in the form of a leaf spring. The latter bears on the top of the boot, constituting a flexible connection to the front and a rigid connection to the sides. A cord allows the spring to be pretensioned towards the front. Straps tightened by securing buckles allow the deformable component to be kept fixed to the boot. By means of the invention, the cross-country skier is able to use walking boots ideal for climbing, while at the same time being able to ski downhill supported by the tibias.

Description

BACKGROUND OF THE INVENTION[0001]The invention relates to a removable tibia support device for a skier, able to be fitted on the skier's boot and comprising a retaining strap encircling the skier's leg and keeping the tibia in contact with a support surface in the form of a padded cast. Such a device is mainly designed for off-track ski walking, but can also be used for alpine skiing, cross-country skiing, telemarking, snowboarding and for any situation requiring a support on the tibia.STATE OF THE ART[0002]Known cross-country ski boots are a trade-off between contradictory qualities: rigidity for downhill runs and flexibility and lightness for uphill progression. The tibia support described in the document FR 2870464 enables the skier to ski with walking boots, and comprises a ski binding associated with a rigid connection between the skier's leg and the attachment system fixed to the ski enabling the inclination of the tibia to be adjusted. The presence of this rigid connection ha...

AI Technical Summary

Benefits of technology

[0005]The object of the invention is to provide a removable tibia support device that can be fitted to a low boot, and that provides improved holding of the skier's leg during downhill skiing.

[0007]The skier can therefore use hiking boots able to accommodate crampons, which are inexpensive, light and ideally supple for uphill walking. The deformable part operates as a leaf of a leaf spring. The stiffness is particularly suitable for downhill skiing.

[0012]rubber strips can be stuck under the mobile part to protect the latter from wear against the rings of the boot and to prevent it from slipping;

Problems solved by technology

The presence of this rigid connection hampers satisfactory operation of the frontal triggering and gives too rigid a support to the tibia without any flexible spring effect.

The aim sought for is to keep the skier's knee in the flexed state, but it does not enable the user to ski by pressing on his or her tibia.

Such a device does not enable the user to ski by pressing on his or her tibia.
