A wheel rim having an axis of rotation, the rim including a first element in the form of a section of a solid of revolution about the axis, made in a single unitary piece from composite material and including a first end and a second end distinct from one another. The first element is made by pultrusion and constitutes, between the first end and the second end, a section of a solid of revolution having an angular arc greater than 350&#xb0;, the composite material of the first element includes fibers embedded in a thermosetting matrix, the fibers constituting at least 50% of the weight of the first element.

Rim or rim portion made of composite material

A tension-spoke wheel including a rim, spokes, and a central hub, the exterior of the rim having a tire-receiving channel that defines a median plane, and an interior of the rim having spoke fastening zones that define a median plane for fastening the spokes, the hub having a median plane and two flanges for fastening the spokes, one of the flanges being closer to the median plane of the hub than the other, and at least the spokes fastened to the flange that is closer to the median plane of the hub lacking individual tensioning mechanisms. The spokes fastened to the flange that is closer to the hub median plane are fastened to the rim on the side of the median plane of the tire-receiving channel that is opposite the closer flange.

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&#x3c;RfB&#x2266;RfC. The invention also relates to a sports boot including such a reinforcement.

Reinforcement for a boot, in particular a sports boot, more specifically a cross-country ski boot, and a boot having such a reinforcement

An aquatic sports garment having an outer layer, provided with at least one multi-layered zone including at least the outer layer and an underlying layer which, in a protective zone, lines the skin in an elastically deformable manner so as to protect it from contact with the outer layer, in that the underlying layer has a fixing zone, whereby it is fixed directly or indirectly to the outer layer, and wherein, at least in the protective zone, the two layers are free from one another.
