Occipital retention strap for cyclist headgear

A protective helmet for cyclist comprising a stabilizing strap and defining a shell having a rear end and a lower peripheral rim portion on which is releasably and adjustably attached said stabilizing strap near said shell rear end, said stabilizing strap comprising a first and a second elongated flexible curved strap members, each strap member comprising:

• a) a first end portion having first attachment means adjustably and releasably attached to the helmet rim portion;
• b) a second end portion having second attachment means adjustably and releasably attached to the second end portion of the other strap member, said second attachment means of said first and second strap members being complementary to one another;
• and
• c) an intermediate ribbed portion, having several widthwise ribs conferring a greater flexibility to said strap member;
• wherein said stabilizing strap defines an operative position when said first and second strap members are adjustably attached to one another by means of said second attachment means to fit the helmet wearer's head near the occipital bone, said second end portions of said first and second strap members being positioned spacedly beneath said rim portion at said helmet shell rear end;
• wherein the combined said second end portions attached to one another by said second attachment means constitute a means for relative movement of said first and second strap members relative to one another, both pivotally about an axis transverse to said attached second end portions, and arcuately along the flexible body of said intermediate portions of said first and second strap members.

A head-restraining member for use on a cyclist helmet, the helmet being of the type having a shell, with internal and external walls and a peripheral edge joining the internal and external walls, and an annular rim, integral to the shell peripheral edge;

• said head-restraining member comprising first and second separate strap members, each strap member being elongated and comprising a main body, made from a flexible material, first attachment means, at an outer end portion of said main body, and second attachment means, at an inner end portion of said main body opposite said outer end portion thereof;
• wherein said first attachment means is for releasably attaching said main body to the helmet shell internal wall proximate the helmet peripheral edge, and said second attachment means of the pair of said strap members are complementary to one another for releasably interconnecting said strap members inner end portions;
• wherein the combined said inner end portions attached to one another by their respective complementary attachment means constitute a means for relative movement of said first and second strap members relative to one another, both pivotally about an axis transverse to said attached second end portions, and arcuately along the flexible body of said main body of said first and second strap members;
• and
• wherein each strap member further comprises a number of spaced-apart, widthwise, substantially ovoidal and parallel apertures thereon.
