Definitions

  • a safety helmet is equipped with a fixing part in the shape of a U-shaped jumper, the internal wing of which engages in an opening made in an extra thickness. from the bottom edge of the helmet.
  • the mechanical locking of the fixing part in the opening takes place by means of two elastic lateral arms, capable of deviating from one another in the plane of the inner wing.
  • the outer wing is provided with an orifice for securing an accessory. There is no elastic movement of separation and reconciliation between the two wings.
  • Such a fastening piece is not suitable for mounting straps.
  • the system for holding the straps of a headlamp comprises elastic bands fixed at predetermined locations on the cap. Each elastic cooperates with a hooking spout secured to the outer surface of the cap by means of a rivet passing through the wall of the cap. Riveting operations complicate the manufacture of the helmet, and the premature aging of the elastic poses a maintenance problem.
  • Document US-A-4479738 mentions an accessory for fixing a visor to a helmet, comprising a support body, having a hooking lug capable of being inserted into an orifice of the helmet, and means of articulation of the visor between a lowered position and a raised position.
  • the fixing accessory is found indoors, and requires several parts to be assembled.
  • the object of the invention is to improve the system for holding an accessory on a safety helmet.
  • the fastening parts are an integral part of the helmet.
  • the clipping avoids any additional riveting operation.
  • a longitudinal space is provided between the two connecting means to allow the movement of the elastic middle branch of the second wing.
  • a rectilinear bearing surface is provided on each connecting bridge to opposite the notch, and is delimited by a first stop and a second stop respectively secured to the first external wing, and to the second internal wing, the spacing between the two stops being greater than the thickness of the wall of the cap.
  • the fastening part is blocked in the opening, on the one hand by means of a step of the end face of the second wing being engaged with a first edge of the opening when coming in. engagement of the bearing surfaces against a second edge located opposite the first edge, and on the other hand by elasticity effect by the action of elastic pressure of the free end of the intermediate branch of the second wing on the inner face of the cap.
  • the accessory is formed by a headlamp associated with a cap with elastic straps.
  • a safety helmet 10 is equipped at the front with a front lighting lamp 12 attached to the outer surface of the cap 14 by a holding system 16 shaped as an elastic cap.
  • the lamp 12 has a base 18 articulated around a horizontal axis 20, and is permanently secured to the elastic cap of the holding system 16, comprising a pair of side straps 22, 24 one of which 22 is shown on the part left of the cap 14, the other 24 is shown in dotted lines on the right part of the cap 14 and a third central strap 26.
  • the three straps 22, 24, 26 conform to the shape of the cap 14, and are produced by means of an elastic ribbon of synthetic textile material, having a predetermined width, in particular between 1 and 7 centimeters.
  • Each strap 22, 24 lateral of the elastic cap extends parallel along the lower edge 28 of the cap 14, and has a length substantially equal to half of the base perimeter of the cap 14.
  • the orientation of the central strap 26 takes place according to a generatrix situated in the median plane of the cap 14 so as to contribute to the stability of the elastic cap on the helmet 10.
  • the two lateral straps 22, 24 of the cover are locked on the outer surface of the cap 14 by means of fastening pieces 30 of identical structures mounted by clipping into openings 31 of shaped conjugate, formed in the wall of the cap 14 above the lower edge 28.
  • Each opening 31 advantageously has a rectangular shape, but it is clear that any other shape can be used.
  • each fixing piece 30 is shaped as a clip or elastic clip, having a first outer wing 32, one end of which is joined to a second internal wing 34 by connecting means comprising two bridges 36 , 38 playing the role of hinges.
  • the two wings 32, 34 are substantially parallel, so as to constitute a semi-open notch 40 in the shape of a U intended to cover the lower edge 42 of the opening 31 during the positioning of the fixing piece 30 on the cap 14.
  • the inner wing 34 of the fixing piece 30 has a lyre structure, having two lateral branches 44, 46 integral with the connecting bridges 36, 38, and an intermediate middle branch 48 serving as a pressure spring for the stable maintenance of the fastener 30 in the corresponding opening 31.
  • the three elementary branches 44, 46, 48 are joined together by the end face 50 extending over the entire width of the inner wing 34, while the free end 51 of the middle branch 48 is projecting from the substantially planar bearing surface 52, 54 of the two connecting bridges 36, 38.
  • a longitudinal space 56 separates the two connecting bridges 36, 38 allowing the deflection by pivoting of the elastic middle branch 48 of the inner wing 34 in a direction F1 (FIG. 4) substantially perpendicular to the outer wing 32.
  • Each side branch 44, 46 of the second inner wing 34 is provided with a protuberance 58, 60 disposed opposite a flat extension 62 of the first outer wing 32.
  • the extension 62 extends over the entire width of the outer wing 32 and is equipped with a first stop 63 formed by the planar internal surface oriented in a direction perpendicular to the bearing surfaces 52, 54 of the two connecting bridges 36, 38.
  • Each protuberance 58, 60 similarly includes a second stop 64 formed by the flat internal surface perpendicular to the bearing surfaces 52, 54.
  • the transverse spacing 65 between the two stops 63, 64 corresponds to the length of the surfaces d 'support 52, 54 rectilinear bridges 36, 38 and is greater than the thickness 67 of the notch 40, as well as that of the wall of the cap 14.
  • the internal end face 50 of the second wing 34 has a locking step 66 extending parallel to the bearing surfaces 52, 54.
  • the free end of the first wing 32 is provided with an oblique entry edge 68 facilitating the introduction of the lateral straps 22, 24 on the fixing pieces 30 mounted on the helmet 10.
  • the distance 70 between the locking step 66 and the bearing surfaces 52, 54 of the fixing piece 30 corresponds substantially to the height 72 of the corresponding opening 31 of the cap 14 (see FIG. 2).
  • the fastening parts 30 are advantageously obtained by molding a plastic material of high mechanical strength, allowing elastic deformation during insertion into the openings 31 of the cap 14.
  • the fixing part 30 is embedded in the opening 31 and forms an integral part of the cap 14.
  • the first stop 63 is in stable support against the outer wall of the cap 14 by the action of the elastic return force, resulting from the abutment of the end 51 of the middle branch 48 against the inner wall of the cap 14 above the upper edge 76.
  • the second stop 64 is separated from the inner wall of the cap 14 by a predetermined interval.
  • the insertion of the strap 22 or 24 into the part 30 takes place on the side of the oblique edge 68 in the direction of the arrow F4 (FIG. 7).
  • the strap 22 slides to the bottom of the notch 40, and causes the attachment piece 30 to protrude, which moves in translation in a direction substantially perpendicular to the cap 14 (arrow F5, FIG. 8).
  • the second stop 64 more or less approaches the internal wall of the cap 14, and can come into contact with it.
  • the first stop 63 is then separated from the outer wall of the cap 14 by a predetermined interval, but the bearing surfaces 52, 54 remain in engagement against the upper edge 76 of the opening 31.
  • the first outer wing 32 clamps the strap 22 against the outer surface of the cap 14 thanks to the pressure force exerted by the end 51 on the inner wall of the helmet 10.
  • the step 66 is still in engagement with the lower edge 42 so as to retain the effect for locking the fixing part 30.
  • the fixing piece 30 can be dismantled by exerting an unlocking force on the lower end of the end face 50, followed by a sliding movement in the direction of the lower edge 42, and a clearance to the left, causing the fixing part 30 to be withdrawn from the opening 31.
  • the end of the end face 50 of the second internal wing 34 is arranged to prevent any unlocking of the step 66 after mounting of the fixing piece 30 in the opening 31. The dismantling of the fixing piece 30 is then made impossible.
  • the orientation of the fixing pieces 30 on the cap 14 can be reversed by making the bearing surfaces 52, 54 cooperate with the lower edge 42, and the locking step with the upper edge 76 of the openings 31.
  • fixing parts 30 on the cap 14 can be reserved for any other accessory which must be attached to the helmet 10.
  • the mounting of the fixing pieces 30 can be carried out in the factory, or by the user himself depending on the nature of the accessory.
