Abstract
A chin strap includes a protective shell including a curved and convex contour extending between lengthwise ends of the shell, the shell further including a first curved edge extending between the lengthwise ends of the shell and a second curved edge extending between the lengthwise ends of the shell. A cross-section along a lengthwise central axis of the chin strap defines a first shell portion including the first curved edge and a second shell portion including the second curved edge. The first shell portion of the cross-section defines a first surface area between the lengthwise central axis and the first curved edge, and the second shell portion of the cross-section defines a second surface area between the lengthwise central axis and the second curved edge, where the first surface area is less than the second surface area.
