ABSTRACT:
An improved protective helmet for use by an infantryman or the like in which a suspension frame of relatively rigid material has a peripheral channel provided at one location around the frame with a slightly inwardly inclined portion adapted to receive a slightly outwardly directed portion of the edge of a rigid outer ballistic helmet body to permit the body to be swung to a position in which the entire edge thereof is received in the channel and in which position the body is securely held by a single fastener. The frame is formed with a plurality of generally upwardly extending fingers which removably receive envelopes carrying pads of resilient material which adapt the frame to accommodate a range of head sizes. A light line or cord is threaded through holes and slots around the frame releasably to secure both the crown assembly straps and the chin strap supports to the frame while maintaining the positions of the strap ends at predetermined locations around the frame. The helmet body is formed of ballistic material sandwiched between rigid molded inner and outer shells.
