Helmet and cheek pad
A helmet includes a helmet body and right and left cheek pads arranged inside the helmet body. The cheek pads each include a first bottom portion including a first outer surface located downward from a lower edge of the helmet body and a second bottom portion including a second outer surface located rearward from the first bottom portion. The first outer surface and the second outer surface form a wearing opening of the helmet and are negative pressure generating surfaces configured to generate a downforce acting on the helmet by having the first outer surface located downward from the second outer surface. The first bottom portion and the second bottom portion are resilient so as to enlarge the wearing opening when receiving force for enlarging the wearing opening and reduce the wearing opening in size when the force is removed.
1 . A helmet comprising:
a helmet body; and
right and left cheek pads arranged inside the helmet body, as viewed from a wearer of the helmet, wherein the cheek pads each include:
a first bottom portion including a first outer surface located downward from a lower edge of the helmet body; and
a second bottom portion including a second outer surface located rearward from the first bottom portion, wherein
the first outer surface and the second outer surface form a wearing opening of the helmet and are negative pressure generating surfaces configured to generate a downforce acting on the helmet by having the first outer surface located downward from the second outer surface, and
the first bottom portion and the second bottom portion are resilient so as to enlarge the wearing opening when receiving force for enlarging the wearing opening and reduce the wearing opening in size when the force is removed,
wherein a lower end of the first outer surface projects from the lower edge of the helmet body more greatly than a lower end of the second outer surface;
wherein the first bottom portion and the second bottom portion are separated by an inclined portion that has an inclined surface angled relative to each of the first outer surface and the second outer surface.
2 . The helmet according to claim 1 , wherein the first outer surface is configured to project further from the lower end of the second outer surface so that the lower end of the first outer surface projects downward from the lower edge of the helmet body and toward a middle of the wearing opening.
3 . The helmet according to claim 1 , wherein the first outer surface is configured to have a gradient so as to be continuous with a curve of an external surface of the helmet body.
4 . The helmet according to claim 1 , wherein the first outer surface includes a rear end located frontward from where the helmet body has a right-left maximum width.
5 . The helmet according to claim 1 , further comprising:
a chin spoiler attached to a front portion of the lower edge of the helmet body.
