Abstract: A head top has a frame for mounting on a user's head. The frame has a viewing opening for a user to see out of the frame. A shield is mounted to the frame, and can be moved between a open and closed positions. A pivot arm connects the shield to the frame and is mounted to the inside of both the frame and shield to avoid exposure. An outer mount and inner mount can also be provided to automatically adjust the width of the head top. A hinge connects them allowing the inner mount to laterally pivot with respect to the outer mount to accommodate users with different head sizes. A forehead member also adjusts to a user's forehead.

Abstract: An inflatable bladder and comfort control device is provided for mounting within headgear. The inflatable bladder and comfort control device have at least one inflatable bladder adapted to be positioned against a user's head. An air supply source is operatively connected to the inflatable bladder to inflate the bladder and provide air to the user. A directional valve is operatively mounted within the air supply source to separate the air supply source into flow paths to inflate the at least one inflatable bladder, and to create air flow adjacent the user. A directional valve controls the air flow to the bladder and the user's face. Comfort openings are in fluid communication with the air flow path to supply air to adjacent a user's head.
