ReFerring new to the drawings, figure 1 illustrates a protective he2,met 2 comprising an outer helmet shell 10 which is preferably ~u&de of a rigid material sash as a polycaxbanate alloy. a rigid thermoplastic, or a thermosetting resin. A pad assembly (not shown in the drawingsy is positioned within the helmet shell 1(? to absorb forces applied against the helmet shell 10, anal p~pvent them from injuring a wearer's head. The protective helmet 2, further eompxises bxarkets 64 supporting a face guard 30, that attach, to the helmet by screws 60 engaged in the novel fasteners 40 anchored to the helmet shell 1~7.
As shown i,n Figure 2, each fa,sterer 40 comprises a rivet 92 and a washer 55. Most preferably, the rivet 92 is made of C1018 nickel coated steel while the washer 55 is m~xde of s.A.~. 1010 steel.
As best illustrated 7n fissures 3 and 4, the rzvet 42 includes a flanged head pc~rtxon 44 defining a first end of the ~~ge a E,~iV.PAR~ 12-13-96 ; 6:43PM ; 1000DELAG:aUCHETIERE-~ 650 W. GEORGIA VCK;~lzm4 21~~R7~
rivet which rests against the outer surface of the helmet shell 10, and an elongated body 4~ including a post part 52. defining a second opposite end of the rivet 42 and a Locking section 46 which has an obround eross--sectional shape izrtermediate the S flanged head portion 44 and the post parfi 52. The rivet 92 further comprises an elongateei aperture 54 that P~ctends longitudinally from the p4st paxt 52 to the flanged head portion 44. The aperture 54 is partially threaded. more specifically the threads extend slang the flanged head portion 44 and the intermediate locking saction 46. The aperture 54 is adapted to accept a screw 50.
The flanged head portion 44 of the rivet 42 is circular in crQSS sectional shape. The flanged head portion 49 extends radially outward beyond the outer boundary of the intermediate locking section 4~ and post part 52 of the rivet 42. It is important that the flanged head portion 44 has an outer diameter that 1S' S7.gnificantly Larger than the outer boundary of the elongated body 43 to prevent it from passing through the apertures in the helmet shell provided to accept the rivet 42.
The intermediate locking section 46 of the rivet 42 is located between flanged head portion 44 and past parfi 52. rt can be manufactured ~~nder a wide assortment of shapes that will 2.5 establish a lacking engagement with mounting apertures 12 of helmet shell 1~, to prevent the latter from turning therein.

Accordingly, the intermediate locking section 9b prevents rotata.an of the fastener 90 within mounting apertures 12 and i.hereby enables the fastener 40 to receive a screw 6Q without having to Manually hold the Fastener 90 with a hand tool such as a screw driver. The length of the intermediate locking section 46, is essentially equivalent to that of the depth of the mounting apertures 22, which is equivalent to the thickness of the helmet shell 10.
Most preferably, the intermediate obround locking section 46 is defined by two apposite parallel surfaces 48 joined by two rounded portions 50.
The past part 52 is preferably circular in cross section and has an outer diameter that is equivalent to the distance between parallel surfaces 48. The thickness of the cylindrical wall is relatively small so as to be malleable to form a secondary head BO by flattening a portion of the post part 52 to spread it radially outwardly and twerlap the washer 55 and thus form a compound flanged structure that secures the fastener 90 to the helmet shell 10 in coopetat~.on with flanged head port~.on 44.
The washer 55 as best illustrated i.n figures 5 and 6 ~.s a washer with a circumferential, radially sloping surface or bevel 59 that surrounds a central aperture 58 at one end and further includes a fiat peripheral ring like portion 57 at the other End.
The dia~aeter of the hole 58 is larger than that of the outer diameter of the post part 52 so as to allow washer 55 to be page 10 EVV.PAR: 12-13-96 ; 6:43PM ; lOUUDELaGAUCHETIEREi 6SU 1~.

As best illustzated in figure 2, the !~elmet shell 10 i.s provided with a pltxrazity of mounting apertures 12, each having a shape which substantiatllr conforms to the intermediate ok~round locking section 46 of rivet 4Z. An acCessorial padding 70 of stiff smooth layer that can be made from a variety of materials such as synthetic material, rubhex~ or leather, is provided on the helmet shell 10 to prevent fastener 40 from damagincl the surface of the helmet shell 10 arid tn cushion the face shield 3a against the helmet shell 10.
The accQSSOxial padding '70 co~npxises twa pairs of apertures, namely a front o)Jround pair 72 and a rear circular pair 74, The fx'ont obround paa.r 72 conform with the shape of the mounti_nq apertures 12 and the intermediate obround locking sect~.on Q6 of fasteners 40. The rear circular pair 74 Conform with the shape 2D of the past part 52 of the rivet 42.
In assem~blinq the Fastener 40 to the helmet shell lfii, as depicted by figure 2, accessorial padding 7o is positioned. over tha edge of the helmet she~.l 10 so as to align front apertures 72 and, rear apartr~res 74 with mounting apez'tures 12. The rivet 42 is then inserted into the sli.qned series of apertures. As best illustrated i.n figures 7 arid 8, th,e flanged head portion 44 raq~o li P.hV.
