Definitions

  • the present invention relates to an arrangement for the anchoring of retaining straps to a helmet-like item of headgear, which is preferably made of a foam plastic material.
  • a previously disclosed method for the anchoring of straps for holding cycle helmets, for example, in place on the head of wearers of said helmets involves causing the straps to run through openings passing all the way through the shells of the helmets and then back again in order to be connected by means of buckles to said loop-shaped strap components.
  • GB, A, 2 177 893 does not comprise any retaining straps which are attached to fastening components moulded into the shell of the helmet, but the disclosed helmet comprises neck straps which are contained internally within the intended space of the helmet which accommodates the neck. Said straps together form a 'Y' and are secured to the helmet with rivets and by means of axles accommodated in sewn strap channels in auxiliary cavities in the shell of the helmet. The straps extend through side-facing openings in the shell.
  • PCT Publication WO, Al, 86/03383 contains details of a helmet, the straps of which are attached to the helmet by means of rivets, etc.
  • EP, Al, 0 052 068 relates to a helmet with straps attached by means of bars accommodated in channels in the straps, which bars are accommodated internally within the cavity of the helmet resting on elements integral with the shell of the helmet.
  • 8703751-1 is the method of connecting helmet straps together with bow-shaped attachments secured inside the helmet shell, although in this case the attachment and the strap are connected to one another outside the shell of the helmet and rivets or similar fixings are also required in order to attach the straps to said strap attachments projecting from the helmet shell, which attachments are also capable of causing damage to the wearer, since they must be of a more rigid and harder material than the strap material.
  • the principal object of the present invention is thus to make available an arrangement of the kind referred to above, which, amongst other things, solves the above-mentioned problems associated with helmets and similar items of headgear which can be used for, amongst other things, traffic, sport or games applications, and which, apart from making available a helmet, etc. , which exhibits retaining straps which exhibit the least possible number of buckles and fasteners, etc.. for anchoring the straps to the shell of the helmet at the correct desired points concealed internally within the helmet shell, also enables the risk of pulling apart the helmet shell via the straps to be reduced and permits easy replacement of the straps, should this be necessary.
  • the purpose of the present invention is also to secure helmet straps of the type which are designed to run down over the cheeks and to be connected together beneath the wearer's chin in such a way that one both avoids injury to the wearer by connecting elements such as rivets and strap attachments which project from the shell of a helmet and projecting more rigid and harder strap attachments. Also, and by no means least important, it is possible to cause the retaining straps to run in a simple fashion outwards from the respective helmet shell at a desired point from the surface which delimits its downward-facing edge, whereby the straps lie at the desired correct distance from the various parts of the wearer's head and thus reduce the risk of chafing, etc. , during use.
  • a retaining strap of the kind in question which is arranged for the retention of the helmet on the wearer's head, is so arranged that, with one part accommodated internally within the shell of the helmet, it is connected to an attachment element moulded into the helmet shell and extends outwards from an internal channel in the helmet shell, which is situated at the surface of the helmet shell which delimits its downward-facing edge viewed with the helmet being held in the normal position in which it is ready to provide protection.
  • Fig. 1 shows a perspective view of a helmet viewed at an angle from below, with the straps and their anchorages to the helmet illustrated schematically;
  • Fig. 2 shows the sequence for the anchoring of a strap to a helmet illustrated in see-through form
  • Fig. 3 shows a helmet strap in its finally anchored state, here too illustrated in see-through form
  • Fig. 4 shows a sectional view along the line IV-IV in Fig. 3;
  • Fig. 5 shows a perspective view of a component part of the anchorage arrangement;
  • Fig. 6 shows a further component part of the anchorage arrangement fitted to a strap
  • Figs. 7-9 show a second illustrative embodiment of the invention in perspective, in section, and in its effective position.
  • a retaining strap 2-5 of the kind in question is also so arranged in accordance with the invention as to be passed around an attachment element F executed, for example, as an attachment bar 8 when a part 2A of said retaining strap 2-5 is so arranged as to be accommodated internally in said shell 7 of the helmet.
  • the expression “internally” is understood to denote a channel 9 which passes all the way through the shell 7 of the helmet in an essentially vertical direction 10, viewed with the helmet 6 being held in the normal position I in which it is ready to provide protection, as shown in Figs. 1 and 4.
  • the expression “internally” can also be understood to denote a channel provided with a bottom.
  • Said attachment bar 8 is preferably so arranged as to interact with a support 11 which is accommodated internally in the helmet shell 7 when the attachment bar 8 is in its anchoring position II, as shown clearly illustrated in the drawings in Figs. 3 and 4.
  • Said attachment bar support 11 can be executed from a material which is harder than the material of which the shell 7 of the helmet itself consists, and the support 11 is suitably in the form of a supporting strip moulded into the shell 7 of the helmet, which extends across the intended direction of pull 12 of an anchored retaining strap 2 of the kind in question.
  • Said supporting strip 11 exhibits an opening 13 for the strap to pass through, and a sleeve-shaped component 14 is appropriately attached to said supporting strip 11, for example on its under side HA, so that said opening 13 for the supporting strip makes contact with the inner lead-through channel 15 for the strap at the upper end 14A of the sleeve-shaped component.
  • Said sleeve-shaped component 14 is introduced into the shell 7 of the helmet when the arrangement 1 is used in a finished helmet 6 , and is preferably moulded into it.
  • Said channel 15 of said sleeve-shaped component 14 appropriately makes contact at its lower orifice 16, which is situated on the lower part 14B of the sleeve-shaped component, with an orifice 17 for the strap to pass through, which orifice is situated at the surface 18 of the helmet shell which delimits its downward-facing edge, and which is situated opposite the orifice 19 of the channel 9 which extends all the way through the shell of the helmet in an essentially vertical sense 10.
  • Said orifices 17, 19, which are situated diametrically opposite one another, are so arranged as to permit the strap 2 in question to be passed through, both when assembling the arrangement 1 and when using the helmet.
  • said retaining strap 2 in such a way as to extend outwards from the shell 7 of the helmet and through said orifice 16 for the strap to pass through which opens into surface 18 of the helmet which delimits the edge of its shell, the strap 2 can be retained at the desired distance from the inside and the outside 6A, 6B respectively of the helmet, thereby achieving the desired location for the position of the strap away from or in towards the helmet 6.
  • the upper part 14A of said sleeve-shaped component 14 which is capable of accommodating the strap exhibits two laterally projecting wings 20, 21 with an interjacent part 22 through which the opening 13 extends.
  • the wings 20, 21 can exhibit walls 23, 24 projecting downwards from said intended support 11 for the attachment bar, which walls can also be attached to the outer generating surface 14 of the sleeve-shaped component 14. With a view to further improving the moulding capability, said walls 23, 24 can exhibit parts intended for moulding, such as the holes 25, 26, which extend into or through the walls 23, 24.
  • the attachment bar 8 is in the form of a rod which, as shown in Fig. 6, is capable of being introduced into a tunnel 27 at one end 2A... of the retaining straps 2-5 in question.
  • Said tunnel 27, which can be formed by folding over the end of the strap to form a loop and attaching it to the strap 2, for example with thread 28, exhibits a length L, viewed along the width of the strap, such that the bar 8 which is accommodated therein projects with a supporting part 8A, 8B at the respective side edges 29, 30 of the strap.
  • These two parts 8A and 8B of the bar are so arranged as to be supported in such a way as to rest on the upper side 20A, 21A of the respective supporting wings 20, 21 when the strap 2 retains the bar 8 in the anchoring position II.
  • the attachment bar 8 and the support 11, which are part of the anchoring arrangement 1, consist preferably of a metallic material and/or of high-quality plastic material which will withstand a high load, so that the straps 2-5 do not work loose from the helmet 6 when pulling on the straps.
  • the attachment of a strap 2 is illustrated schematically in Figs. 2 and 3.
  • the end 2A of the strap with the tunnel 27 is introduced from the under side of the helmet and up 31 through the orifice 16 of the sleeve-shaped component at the lower orifice 17 of the channel 9 and up through the channel 15 , onwards through the upper pait 9A of the channel . and then out through the upper orifice 19 of the channel to the upper side 6A of the helmet, as shown in Fig. 2.
  • the bar 8 is introduced here in the direction of the arrow 32 into the strap tunnel 27, whereupon the strap 2 can again be pulled downwards in the direction 33, so that the bar 8 is drawn down into the orifice 19 and the channel 9.
  • the length A of the bar 8 must naturally be less than the width B of the channel 9, but must exceed the width C of the channel 15 and the opening 13, so that the projecting parts 8A, 8B of the bar can rest on the support 11, and in actual fact on the wings 20 , 21 in the anchoring position II of the strap 2.
  • the possibility is provided for dismantling the strap 2 by proceeding in the reverse sequence.
  • the possibility is provided for plugging the channel 9 at its upper part 9A, partly in order to prevent the end 2A of the strap with its associated anchoring bar 8 from rising up out of the channel and becoming detached from one another, and partly in order to prevent rain and snow from finding their way down into the channel 9 so that water runs down along the straps 2- 5 in question.
  • a removable plug which, for example, fits into a recess 34 situated above the channel 9, may be appropriate in this case.
  • each of the front straps 2, 3 is attached to an arrangement 1 of its own, whereas the rear straps 4, 5 are attached to a common arrangement l 1 , although this is executed and functions similarly to the indicated arrangement 1, whereby a common bar is utilized for the two bars 4, 5, although individual arrangements 1 can naturally also be applied for the rear straps 4, 5 or other anchoring arrangements which lie beyond the scope of the present invention.
  • FIG. 7 The example of a helmet strap attachment arrangement 101 illustrated in Figs. 7 and 3 shows,how a strap 102 is attached in an internally concealed fashion within the shell 107 of a helmet 106.
  • a rivet, a bolt or some other suitable separate attachment device 150 is so arranged as to be connected to a part 102A of a retaining strap of the kind in question, which is so arranged as to be enclosed within the shell 107 of a helmet at the strap anchorage point CII with the attachment device 150 interacting with an attachment component CF moulded into the shell 107 of the helmet, which attachment component, like the attachment component in the previous embodiment, can exhibit the form of a letter 'T' with a lead-through channel 115 for the strap, which extends along and through the staple-like part 114 of the attachment component.
  • the attachment device 150 extends across the strap 102 and rests above the attachment component CF, for example in a recess in the abutment part 111 of the attachment component extending laterally in relation to the direction of pull of a retaining strap 102 of the kind in question, in actual fact the cover component of said T-shaped attachment component CF.
  • the assembly of the attachment device 150 to the strap 102 is possible from the upper surface of the helmet, for which purpose the strap is introduced through the part 114 of the attachment device and projects with the end 102A of the strap facing upwards so as to permit access to the end 102A of the strap, so that a rivet 150, etc.
  • the strap 102 can be attached to the strap 102, which rivet, etc., after the strap 102 has been pulled down, is accommodated by the attachment component CF and is concealed internally within the shell 107 of the helmet, with said attachment arrangement 101 5 totally concealed within the delimiting surfaces of the helmet.
