- the looped end is indicated by numeral 5' in Fig. 8.
- a locking pin 6, Received in the looped end 5' is a locking pin 6, which is also made of synthetic resinous material and terminates in two resilient legs 7 and 8 as shown in Figs. 4 and 5, which are provided with projections 7' and 8' which are resiliently received in the recesses 2 and 2" of the bridge 2, to prevent the movement of the pin 6, and therefore the loop 5', upwards in use.
- the diameter of the pin 6 is greater than the width of the slot 3 of the bridge, to prevent the loop 5' from slipping through the slot 3,4.
- Each mounting is provided with a cover plate 9 which is also of synthetic plastics material, and is provided with resilient projections 9 and 9", which serve to hold the cover in the opening 3', as shown in Fig. 2, to cover said opening.
- the opening 3' occurs with the stamping out of the bridge 2.

Abstract
Description
- This invention relates to protective helmets, which are used by, for example, motor cyclists and pedal cyclists, scooter riders and moped riders, and which are of a type provided with chin straps in order that the helmet may be held securely to the user's head. The most commonly known protective helmet for motor cyclists have chin straps which are secured by means of metallic pins or iron plates which plates in turn are rivotted to the inside of the helmet shell.
- There are known other fixing arrangements in protective helmets, but invariably these arrangements include metallic connecting parts.
- When metallic parts are used, it frequently happens that due to the action of inclement weather or because of perspiration of the user, the metallic parts become oxidised, and if made or iron or steel rusting, which on the one hand makes them unsightly, and on the other hand and more seriously weakens them to such an extent that they may fail in use when subject to stress which could be extremely dangerous in the case of impacts and accidents.
- The present invention seeks to provide a helmet, the helmet shell, and a method of making a helmet shell whereby the utilisation of metallic parts for the fixing of the chin strap of the helmet is obviated thereby avoiding the abovementioned drawbacks.
- In accordance with the present invention, in a first aspect, a protective helmet comprising a head protecting shell of non-metallic material having chin strap mountings at respective sides thereof, and a chin strap, is characterised in that at least one of said mountings includes a support of non-metallic material which is integral with the shell and a non-metallic complimentary locking member which co-operates with the support thereby to lock the chin strap to the shell, whereby the use of rivets, screws, studs or other metallic parts is not necessary.
- Also in accordance with the invention, there is provided a head protecting shell of a protective helmet as aforesaid, wherein the shell is of non-metallic material and has chin strap mountings at the respective sides thereof, said shell being characterised in that at least one of said mountings comprises a support stamped out from or moulded with the shell.
- In yet another aspect of the invention there is provided a method of making a protective shell of a protective helmet provided with supports for a chin strap at respective sides of the shell, wherein the shell is formed in non-metallic material and at least one of said supports is stamped from or moulded with the said shell.
- The shell of the helmet may be made of stampable themoplastic synthetic resin or of polyester resin reinforced with glass fibres, and the said support may be formed by stamping or mechanical moulding, and may comprise a bridge which is ipported spaced inwardly of the inner surface of the shell by bridge legs at the end of the bridge, so as to define a bridge slot through which an end loop of the chin strap passes, said complimentary part in such case comprising a locking pin which is of greater diameter than the width of the said slot and which passes through said loop of the chin strap, said locking pin being of synthetic plastics material.
- The said locking pin may be provided with two resilient locking legs provided with projections which are adapted to spring into locking engagement with recesses or ledges in the bridge legs, thereby to prevent the movement of the locking pin upwards relative to the bridge.
- With the formation of each bridge there may be formed an aperture in the outside of the shell, and such aperture is preferably covered by means of a cover plate which is provided with resilient projections which serve resiliently to lock the cover plate in position covering said aperture.
- An embodiment of the present invention will now be described, by way of example, with reference to the accompanying drawings, whererein:-
- Fig. 1 is a view of one side of the inside of the helmet shell, showing the integral support at that side, a similar support being provided at the other side;
- Fig. 2 shows the support shown in Fig. 1 when viewed from the outside of the helmet;
- Fig. 3 is a cross-section taken through the support shown in Figs. 1 and 2;
- Fig. 4 is a view similar to Fig. 1, but showing the locking pin in operative position;
- Fig. 5 is a'side view of the locking pin shown in Fig. 4;
- Fig. 6 is a plan view of an outer cover plate;
- Fig. 7 is a cross-sectional view of a cover plate shown in Fig. 6 ; and
- Fig. 8 is a cross-section similar to Fig. 3, but showing the complete assembly, and the loop end of the chin strap held by the assembly, and the cover plate applied.
- Referring to the various figures, it is to be mentioned that the helmet shell 1 is provided with two chin strap mountings, one at each side and one only of which is described, and the said shell is made in this example of stampable elastic synthetic resin (it may be of polyester resin reinforced with glass fibres), and has formed by stamping or mechanical moulding on each side a
locking bridge 2 which is spaced from the inside of the helmet by means of bridge legs at the ends ofbridge 2, so as to define a slot orloop hole 3,4 to receive the looped end of thechin strap 5. The looped end may be formed by folding the end of the strap and sewing the folded end to the remainder. The looped end is indicated by numeral 5' in Fig. 8. Received in the looped end 5' is alocking pin 6, which is also made of synthetic resinous material and terminates in two resilient legs 7 and 8 as shown in Figs. 4 and 5, which are provided with projections 7' and 8' which are resiliently received in therecesses bridge 2, to prevent the movement of thepin 6, and therefore the loop 5', upwards in use. - The diameter of the
pin 6 is greater than the width of theslot 3 of the bridge, to prevent the loop 5' from slipping through theslot 3,4. - Each mounting is provided with a
cover plate 9 which is also of synthetic plastics material, and is provided withresilient projections bridge 2. - It will be clear that in the arrangement described there are no metallic parts, and therefore oxidation, corrosion and wear of parts due to oxidation and corrosion are excluded absolutely, ensuring the long term efficiency of the strap attachments.
- The shape of the various parts making up each of the mountings or attachments for the strap may vary without departing from the scope of protection as defined in the appended claims.
