Clip-free helmet visors
View Patent ↗A visor removably attached to a helmet includes a brim, a first wing extending from the brim, a first prong from the first wing engaging with the first side vent. A second wing opposite the first wing extends from the brim, a second prong from the second wing engaging with the second side vent. A distance between the first prong and the second prong is smaller than a distance between the first front wall of the first side vent and the second front wall of the second side vent, the first prong and the second prong respectively engaged with the first side vent and the second side vent through tension in the visor resulting from expansion of a wingspan between the first wing and the second wing.
1. A helmet comprising:
a helmet body forming an energy-management liner, the helmet body comprising an outer surface, an inner surface opposite the outer surface, a rim extending between a lower edge of each of the outer surface and the inner surface and comprising a first side, a second side, and a front between the first side and the second side, and one or more recesses on the outer surface of the helmet and adjacent the front of the rim, the helmet body further comprising a first side vent on a first side of the helmet body and a second side vent on a second side of the helmet body opposite the first side vent, the first side vent disposed through the energy-management liner adjacent the rim of the helmet body and comprising a first front wall proximate the front of the rim, the second side vent disposed through the energy-management liner and adjacent the rim of the helmet body and comprising a second front wall proximate the front of the rim; and
a visor removably coupled to the helmet body, the visor comprising:
a brim comprising a front facing away from the helmet body and a back facing toward the helmet body;
a first wing extending from the brim and toward the first side vent, the first wing further comprising a first prong extending inwardly toward the inner surface of the helmet body, the first prong engaging with the first side vent at the first front wall of the first side vent;
a second wing opposite the first wing, the second wing extending from the brim and toward the second side vent, the second wing further comprising a second prong extending inwardly toward the inner surface of the helmet body, the second prong engaging with the second side vent at the second front wall of the second side vent; and
one or more protrusions projecting from the back of the brim of the visor, the one or more protrusions engaging in the one or more recesses;
wherein a distance between the first prong and the second prong is smaller than a distance between the first front wall of the first side vent and the second front wall of the second side vent, the first prong and the second prong respectively engaged with the first side vent and the second side vent through tension in the visor resulting from expansion of a wingspan between the first wing and the second wing.
2. The helmet of claim 1 , wherein the visor comprises a first protrusion and a second protrusion, the first protrusion and the second protrusion disposed substantially symmetrically about a centerline of the visor.
3. The helmet of claim 1 , wherein the first side vent further comprises a bottom wall proximate the rim, and wherein the first prong extends from a top of the first wing, the first wing disposed between the bottom wall of the first side vent and the first side of the rim.
4. The helmet of claim 1 , wherein a bottom of the first wing curves toward the helmet body.
5. The helmet of claim 4 , wherein an end of the first wing follows the outer surface of the helmet.
6. A visor for a helmet, comprising:
a brim comprising a front and a back opposite the front;
a first wing extending from the brim and curving rearward;
a second wing opposite the first wing, the second wing extending from the brim and curving rearward, the second wing and the first wing facing each other; and
one or more protrusions projecting from the back of the brim of the visor, the one or more protrusions configured to engage in one or more recesses on an outer surface of the helmet;
wherein the first wing further comprises a first prong extending from the first wing toward the second wing, the second wing further comprising a second prong extending from the second wing toward the first wing, a distance between the first prong and the second prong is smaller than a distance between a first engagement point on a first side vent and a second engagement point on a second side vent of a helmet, the first prong is configured to engage with the first engagement point on the first side vent of the helmet through a horizontal tension of the first wing caused by an expansion of a wingspan between the first wing and the second wing, and the second prong is configured to engage with the second engagement point on the second side vent of the helmet through the tension of the second wing caused by the expansion of the wingspan.
7. The visor of claim 6 , wherein the visor comprises a first protrusion and a second protrusion, the second protrusion disposed on an opposite side of a centerline of the visor from the first protrusion.
8. The visor of claim 6 , wherein the first prong extends from a top of the first wing.
9. The visor of claim 6 , wherein a bottom of the first wing curves toward the second wing.
10. The visor of claim 9 , wherein an end of the first wing follows an outer surface of the helmet.
