ABSTRACT:
A new helmet mirror comprises an articulated two-piece body having the mirror on one piece and an attachment device on the other piece. For most applications the attachment device comprises an adhesive for attachment directly to the clear face shield of a snowmobile helmet. The mirror and the adhesive are on the back of the respective pieces and the fronts of the respective pieces are smoothly contoured to reduce wind resistance and aerodynamic forces applied to the mirror body at high speeds. In an alternative embodiment a third piece comprising a link joins the mirror piece to the attachment piece with two articulation joints. The link is aerodynamically shaped to substantially reduce vibration of the mirror at high speeds and thereby reduce the forces applied to the articulation joints which retain the mirror in the proper viewing position.
