Abstract
Conical face shields, sports helmets, and methods for orienting a conical face shield in a sports helmet are described. In embodiments, the conical face shield has at least two opposing arcuate edges, at least two opposing side edges, and a shield. The arcuate edges each have a first end, a second end, and an edge surface extending between the first end and the second end. Further, the edge surface of the first arcuate edge and the edge surface of the second arcuate edge include an arc segment and the arc segment of the edge surface of the first arcuate edge is part of an ellipse with a greater semi-minor axis than the semi-minor axis of the ellipse forming the arc segment of the edge surface of the second arcuate edge. In various other embodiments, the conical face shield may be horizontally and/or vertically tapered.
