Abstract: A bicycle helmet that allows ventilation to a cyclist head. The helmet comprises a hard internal shell, a hard external shell, and a shock absorbing foam insert located between the internal and external shells. The helmet consists of a generally open concave structure having a number of fore and aft extending structural arms, transversely spaced from one another and merging with an annular bottom edge rim at both their fore and aft ends. Each structural arm forms a U-shape in cross-section, for reinforcing the helmet structure. The shock absorbing foam of the insert engages with the grooves formed by these cross-sectionally U-shape structural arms. Air ventilation passages are formed in between each pair of successive U arms, extending through corresponding openings in the shock absorbing insert and through the open mouth formed by the annular internal shell. The radius of curvature of the structural arms is greater than that of the shock absorbing insert.

Abstract: A flexible seat pad for fitting onto the inside crotch portion of a cyclist, the seat pad consisting of a generally convex unitary flexible sheet member, the sheet member defining: a number of pad bulges, integral to the sheet member, the pad bulges being resiliently compressible; and hinge lines, hingedly interconnecting adjacent pairs of pad bulges. The hinge lines assist in enabling said flexible sheet member to conformingly fit onto the inside crotch portion of the cyclist for dynamic comfort of the cyclist during pedalling.

Abstract: An athletic sock for insertion into a shoe, the sock defining a generally tubular body having a mouth at one end, the mouth for engagement by the foot of a person, a first portion of the tubular body including a resilient elastomeric compound, at least a fraction of the first portion of tubular body destined to be exposed out from the shoe during use, the first portion defining an external surface having a fine grain, and a high resolution printed design layout being mounted to the external surface of the first sock portion integral thereto.

Abstract: The present invention is a stabilizing strap for a cyclist helmet which comprises two flexible elongated strap members which are adjustably and releasably attached at their first end to the interior surface of the helmet rim portion, at the rear end of the helmet, by means of hook and loop fasteners. The strap members are adjustably and releasably attached at their second end to one another also by means of hook and loop fasteners. The curved strap is destined to bear on the occipital bone of the head, to prevent the helmet from accidentally tilting frontwardly, especially as a result of an impact. The flexibility and the several adjustments of the stabilizing strap allow it to fit heads of different sizes and shapes.

Abstract: The helmet includes a shell, made of polystyrene, and a rim, made of polypropylene and integrally connected to the shell. Both the shell and the rim have air ventilation apertures. Chin straps integrally depend from the internal face of the shell. The shell and the rim are interconnected by cross-sectionally L-shape fingers, integral to the rim, and complementary cavities, made in the shell peripheral edge and engaged by the fingers. The rim apertures are obliquely inclined at the lateral sides thereof, to promote air ventilation around the wearer's head. A set of arcuate metallic wires, embedded into the helmet and preferably made of titanium, may also integrally interconnect the shell to the rim.

Abstract: The spherical flexible sheet lens is releasably secured to and within the channel of an eyewear frame. The lens defines two distinct lens elements and a bridge part spacedly integrally interconnecting the first and second lens elements. The bridge part includes a nose opening for free passage of the wearer's nose. A transverse lip forms the top of said lens to be inserted within the channel and secured to the frame. Each lens element: is of generally spherical shape; is thickest in its center portion and gradually thinner towards its edgewise portion to control the optical distortion brought about by a curved plastic lens; is adapted to register with a corresponding one of the two eyes of a wearer; defines an interior surface in facing register with the wearer's face and an exterior surface; includes an inturned web interconnecting the top and inner sides of each lens element to the lip and bridge part, respectively, the lens element being outwardly offset relative to said lip and bridge part.

Abstract: This invention relates to a protective helmet for a cyclist having a conventional shock-absorbing shell and a fastening strap. The rear part of the fastening strap is threaded through an abutment plate which is slightly concave and destined to bear on the occipital bone of the head of the cyclist. The front part of the fastening strap is attached to the front part of the helmet. The abutment plate is attached to a loop band which hangs from the rear part of the helmet. When the cyclist puts the helmet on and fastens the fastening band, the abutment plate bears on his occipital bone to prevent the helmet from tilting frontwardly in the sagittal plane.
