A bicycle helmet (10) includes an inner layer (12) having a concave shape, an outer layer (18) having a convex shape, and a sun visor (20). The outer layer (18) covers the inner layer (12) and includes an outer layer attachment member (34) and an outer layer lock member (36). The sun visor (20) includes a shade member (56) and a sun visor attachment member (54)connected to and distal to the shade member (56). The sun visor attachment member (54) is adapted to rotatably engage with the outer layer attachment member (34) to form a fulcrum. A sun visor lock member (60) is adapted to operatively engage the outer layer lock member (36) so as to releasably lock the sun visor (20) into a fixed position. The sun visor lock member (60)and the outer layer lock member (36) operatively engage so as to allow the sun visor (20) to be releasably locked into one of a plurality of fixed positions. The sun visor attachment member (54) and the outer layer attachment member (34) rotatably engage via a snap fit fastener. |
