A device for binding a boot to a cross-country ski, the device fixing the front of the boot to the ski while allowing the rear of the boot to move relative to the ski between a low position and a high position. The device includes an elastic return system for applying an elastic return force to return the boot to the low position, and an elastic abutment operable at the end of travel of the boot toward the high position.
摘要:
A device for binding a boot to a sports article, of the type including a retaining system through which the boot is fixed to the sports article with a possibility to move relative to the sports article, between a low position and a high position, of the type including a system for the elastic return of the boot toward its low position, and of the type in which the retaining system functions independently of the elastic return system, and in which the elastic return system is part of a pre-assembled unitary module.
摘要:
A device for retaining a foot or a boot on a sports apparatus, the device including a lateral portion and a medial portion demarcating a zone for receiving the boot, as well as at least one linkage connected to each of the lateral and medial portions by a lateral fastener and medial fastener: The lateral fastener and medial fastener of the linkage are arranged asymmetrically heightwise on the device.
摘要:
A reinforcement for a boot, in particular a sports boot, more particularly a cross-country ski boot. The boot reinforcement makes it possible to improve the torsional stiffness, efficiency, durability, lightness, cost, foot protection, and industrial workability. To achieve this goal, the boot reinforcement according to the invention includes a front zone A from the front end up to the beginning of the plantar arch, a median zone B corresponding to the plantar arch, a rear zone C. The reinforcement includes, at least in the zones B and C, at least one “sandwich” structure constituted by at least one core inserted between at least two layers, and, in the zone A, it is flexible in a substantially longitudinal direction and torsionally stiff. The layers of the sandwich structure are made of composite, carbon fibers/polymeric resin, whereas the core of this sandwich structure is made of synthetic foam, wood or honeycomb. Each zone A, B, C has a longitudinal flexural strength RfA, RfB, RfC, such that RfA
摘要:
Reinforcement element made of a composite material constituted of a layer of inextensible textile material and a layer of polymeric material assembled to the layer of textile material during a molding or vulcanizing step. The textile material is a woven or mesh material, and the textile material is a polyester, polyamide, polypropylene or glass fiber based material. The polymeric material can be a thermosetting material, such as rubber or silicone, or an injected thermoplastic, such as polyurethane, polyvinyl chloride, or polypropylene. Advantageously, the polymeric material is at least partially transparent. The composite material can be incorporated in a boot or a binding, such as a snowboard binding, in the form of a tightening strap. The invention also relates to a method of manufacturing such reinforcement element.
摘要:
A ski boot having a rigid shell made of a plastic material, in which an inner comfort element is inserted, the rigid shell including a collar fixed on a shell base. The boot has a softening structure located on the outer wall of the boot and which includes a plurality of recesses provided in the rigid shell. The recesses are provided in the ankle joint zone, in the lower portion of the outer wall of the shell base, and on the outer wall of the collar.
