Definitions

  • 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.
  • the present invention seeks to provide a protective helmet, whereby the utilisation of metallic parts for the fixing of the chin strap of the helmet is obviated thereby avoiding the abovementioned drawbacks.
  • a protective helmet comprising a head protecting shell of non-metallic material and a chin strap mountings at respective sides thereof, said mountings including a support integral with the shell, and a locking member which is also of non-metallic material and which co-operates with the support thereby to lock the chin strap to the shell, characterised in that the support comprises a bridge stamped out from, or moulded with the protective shell the bridge 12 being supported and 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; a complementary part of said bridge comprising a locking pin which is greater in diameter than the width of said slot and which passes through the said loop of the chin strap, said locking pin having resilient locking legs which respectively resiliently lock to the bridge legs to prevent the locking pin in use from moving upwardly relative to the bridge; an aperture being formed in the shell to allow the stamping or moulding of said bridge, which aperture is closed by a cover of synthetic
  • 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.
  • 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.
  • 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 of bridge 2, so as to define a slot or loop hole 3, 4 to receive the looped end of the chin 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.
  • 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.
