Definitions

  • This invention relates to a crash helmet with retractable elements, which elements when the helmet is not in use can be retracted and collected together one upon another so as to occupy a minimum space.
  • Helmets of this type are for example described in US-A-3514787, FR-A-2490466, US-A-3991422 and US-A-4091470 Patents.
  • a crash helmet of the type comprising a plurality of arcuated elements, said elements being articulated to one another.at the ends so as to be shiftable between two extreme positions, i.e. between a first operative spread position in which said elements are mutually set apart so as to give rise to a cap structure and a second non-operative retracted position in which said elements are collected and overlapped together, so that the helmet dimensions are substantially the same as those of a single element, means being also provided for mutual articulation and mutual engagement of said elements when in the spread position, said latter position being therefore steadily held, characterized in that said articulation means include a plurality of eccentric discs, one for each element, said discs being integrally fixed to an operating stud which is provided on its end facing the inner part of the helmet with a tightening disc and on its other end is provided with a knob pivoted on said stud, said knob having a shaped portion for cooperating with a cam fixed on said stud to draw closer all the spread
  • the crash helmet comprises a gap generally indicated with the reference numeral 10, formed by a plurality of arcuated elements 11 mutually hinged at their ends by means of studs 12.
  • Said arcuated elements 11 can thus be moved from the spread or open position as shown in Fig. 1 to the retracted or closed position shown in Fig. 2; in the latter position the cap elements occupy a minimum space.
  • elements 11 can have the edge portions provided with hooks 14, 15 (Fig. 3).
  • a crash helmet according to the invention is generally indicated with the reference numeral 16 and includes a plurality of arcuated elements 17 mutually articulated at their opposed ends.
  • Figs. 7 and 8 of the drawings The articulation arrangement of said elements 17 is clearly shown in Figs. 7 and 8 of the drawings, and is comprised of a plurality of eccentric discs 18 (one for each element 17), the discs being integral with an actuation stud 19.
  • Said stud 19 is provided at the end toward the inner part of the helmet with a padded locking disc 20, and at the other end is provided with an articulated knob 21 having a shaped portion 22 cooperating with a cam 23.
  • the cam 23 is integral with the actuation stud 19.
  • Said knob 21 is provided also with an aperture 24 for connecting a throatlatch 25.
  • Said locking means can be implemented by protrusions 26 mating with recesses 27.
  • End abutments 28, 29 provided on the elements 17 (Figs. 9 and 10) or mutually opposed teeth 30, 31 (Figs. 11 and 12) cooperate with said protrusions 26 and recesses 27.
  • Said locking means (26, 27, 28, 29 and 30, 31) can of course be arranged and located elsewhere on the cap 10, along the dashed lines shown in Fig. 4.
  • a folding padding 32 which can be made of a suitable microcellular material having a high energy absorbing power.
  • the stud 19 and the eccentric discs 18 are also rotated, causing the elements 17 to approach one another and therefore causing the mutual engagement of the locking means 26, 27 or 30, 31.
  • Said locking action is implemented by the engagement of the said locking means, with which can cooperate also friction means 32 interposed between adjacent eccentric discs 18.
  • crash helmet of the invention can be conveniently utilized by any kind of user, such as motorcyclists, mountain climbers, workers, etc. and in any situation in which head protection is needed or even simply advisable.
