inoludes such devioes as chin and head means are readily removed so that other persons oan use the each person supplying his own fitting so that each helmet is personalized to the Suoh provides sanitary exchangeabilit between persons as well as individual fitting If additional oan be used beneath the fitting means so as to provide a range of In the preferred the groove comprises a dovetail groove in whioh the fitting means may be arranged longitudinally of the and in alternative embodiment a fitting ring is sna ble into a groove at the edge shell of the helmet the ring having the dovetail Eaoh of the fitting means snaps into the internal struoture oan e secured to the fitting ring so that the entire internal head engaging structure of the helmet may be removed from the helmet as a the helmet is also arranged for the exterior securement of an additional helmet shell shell This additional helmet is preferably of heavy material so that it oan serve as additional protection from unusually dangerous suoh as are enoountered in com Helmets are well known the The purpose of helmet is to protect the of the Helmets plish this purpose when they have means that permit an accurate fit on the head of the wearer by the head engaging means of the a possibility must be due to hygienlo to ezohange or replaoe the head engaging means in a This particularly so in Civil De ense organizations where one single within a particular tim is worn by a number of Similarly to the other portions of the head engaging it is necessary that those accessories whioh are engaged on the head o the carrier can be individually For the strap head engaging pads must be The most useful positio of the strap is dependent on the configuration of the of the neck the o of the A need also exists to provide adjustability of additional aooessories with respeot to the Such additional aooessories not neoessari2y attaohed to the head engaging means of the For example a head a throat protective facial and neck ear functional may be attached to the particularly in military use of helmets for parades and in there is a need to wear helmets of different It is convenient to wear a relatively light helmet for At parades a similarly built light helmet is pre erably Combat puts completely different demands on the helmet and normally requires a different it is inconvenient to provide a special helmet for each of these oooasions and a is present to adapt one helmet type in a simple manner to the These needs are but the the prior art do not presently satisfy it is an of this invention to

oan be resiliently pressed to the level of The insert pieoes are slid into the fastening ohannel in this Due to the elastioity of the material of the insert the pr will gain stand out when in groove thus filling out the profil of groove so that insert piec is securely Should it b desirable to manufacture the insert pieoes from a nonresilient then to b interrupted by so that the insert pieoes could be inserted and slid laterally into the Due to the snap in arrangement of one or more intermediate pieoes accessories may be plaoed in th ddsired position radially of the fastening as this becomes may be helpful for support for the position of cushion is determined by the head of wearer indicated by lines in Such a use of mediate piece 4 is shown to the left in 3 and i detail in In order to spacer piece 4 is provided with groove corresponding to fastening which oan reoelve an additional intermediate piece or an By virtu of this arrangement of intermediate pieoes one or may be used to adjust the distanoe of the in shell question from the inner surface of the helmet 1 to any As shown in the intermediate pieoes are provided with additional fastening grooves 14 at their upper
