Abstract: A motorcycle helmet is provided which has a sliding visor that moves on tracks on opposite sides of the eye area of a wearer's face. The visor slides relative to a casing which envelopes the back, side and crown of a wearer's head to selectively expose and shield the wearer's eyes. A chin guard is hinged to one side of the casing and a latch mechanism with a release actuator is located on the opposite side. An inflatable bladder, located within the chin guard, serves as a cushion and can be inflated by the user once the jaw guard is latched. Operation of the release actuator to unlatch the jaw guard causes the bladder to deflate.
