Patent ID: 8069499

Claim:
A helmet shield attaching mechanism comprising a shield attaching base member attaching to a head protecting body, and a shield, a portion near one of right and left ends of which pivotally attaches to said shield attaching base member, said shield attaching base member comprising a stationary base member fixing to said head protecting body, and a movable base member attaching to said stationary base member so as to be linearly reciprocally movable with respect to said stationary base member, and said shield being pivotally supported by said movable base member, wherein any one of said shield and said stationary base member is provided with at least one cam surface, the remaining one of said shield and said stationary base member is provided with at least one cam follower to be able to abut against said at least one cam surface, and when a substantially upward force acts on said shield which is in a substantially fully-closed state, said cam follower relatively follows said cam surface to move said shield, together with said movable base member, forward substantially to a front side with respect to said stationary base member, further comprising at least one elastic biasing means capable of elastically biasing said movable base member toward said stationary base member substantially to a rear side, at least one stopper provided to said stationary base member, and at least one stopped portion provided to said movable base member, wherein when said elastic biasing means elastically biases said movable base member and holds said movable base member at a backward position, said at least one stopped portion abuts against said at least one stopper, and said elastic biasing means comprises a compression coil spring.
