Definitions

  • the present invention relates to protective helmets used in particular by motorcyclists, racers, etc. and it relates more particularly to a mobile screen device for helmets of the so-called "integral" type, that is to say comprising a part made of material and extending around the user's chin.
  • a transparent screen articulated on the helmet so that it can be moved between a position of use in which it is folded down to hide the opening of the helmet, and a raised position in which he releases this opening.
  • This screen is usually made of a relatively flexible transparent plastic material comprising, at appropriate points, articulation means cooperating with complementary means provided on the helmet.
  • articulation means are pins or bosses which project outwardly from the helmet shell and the edges of the screen always form continuous projections in the closed position.
  • the cap has a raised part laterally on each side, these raised parts delimiting a shoulder directed towards the front and having a slot in which is frictionally introduced in the folded position of the screen, a tab integral with the latter, the friction of this tab in the shell of the helmet helping to keep the screen more firmly in the closed position.
  • the axes of articulation of the screen are set back with respect to these projecting lateral parts whose contours are rounded so as to avoid as much as possible the risks of snagging.
  • the invention aims to remedy these drawbacks by making a protective helmet for example for motorcyclists, of the so-called "integral” type, comprising an integrated screen device, having no external projection and in which the screen, flexible or rigid is positively locked in the closed position while being very easily open without actuating any locking mechanism.
  • a protective helmet comprising a folding screen having lateral articulation members by means of which it is articulated on the opposite sides of the helmet, characterized in that the upper edge of the or vertex closed by the screen has a projection forming a stop, the distance between the top of said stop at its midpoint and the axis connecting the points of articulation of the screen being slightly greater than the radius of the circular path followed by the midpoint of the top edge of the screen.
  • the screen is a sheet of an elastically deformable material, molded in shape or not.
  • the helmet has a hole at the locations of the axes of articulation of the screen and an elastic inner plate comprising a boss extending towards the outside of the helmet and suitable for closing said hole. , said plate delimiting with the lateral border of the opening of the helmet a slot adapted to receive a tab formed at each end of the screen and constituting said articulation members thereof.
  • Fig.1 Partly shown in Fig.1, the shell of a conventional helmet 1 having an opening at the front, intended to be closed by an articulated screen E.
  • the front opening of the helmet is formed by a peripheral edge 2 which delimits a strip 3 which is slightly set back and which is limited on the one hand by an elastic lip 4 and, at its junction with the shell, by a bead 5 in projection, the bead 5 extending over the upper part of the periphery of the front opening of the helmet and the lip 4 over the whole of this periphery.
  • the bead 5 has, in section, a height progressively increasing from the surface of the shell and, on its side delimiting the strip 3, a height rapidly decreasing forming a rounded shoulder (Fig. 1) directed downwards.
  • the height of the bead 5 being slightly greater than the thickness of the plate of transparent material constituting the screen.
  • the screen E is constituted in a manner known per se by a polycarbonate plate and comprises at each end a rounded tab 6 having as a whole the shape of a hook whose tip 17 has a hole 8 for the passage of an axis articulation as will be explained below.
  • the external curved part of the tab 6 extends beyond the tip 7 of the hook forming a pronounced elbow whose apex 9 is rounded.
  • the lateral end of the screen E has been shown in FIG. 1, developed flat so as to show the shape used, which is identical to the two ends of the screen.
  • Figs. 2 and 3 clearly show the arrangement of the means of articulation of the screen on the helmet.
  • the shell 1 of the helmet is lined in a known manner by a cap made of an elastic or energy absorbing material designated as a whole by the reference 10 and comprises, in the vicinity of its lower lateral edge, a fixing member 11 for a chinstrap 12.
  • the chin strap fixing member is a loop 11 in inverted U which maintains fixed on the inner wall of the cap, in the lateral part of the latter, an element 13 which is advantageously also made of polycarbonate, but not necessarily transparent, and which carries an axis of articulation for the screen E.
  • the internal element 13 comprises a base 14 forming a spacer between the cap of the helmet 1 and the shell.
  • a lug 15 of reduced thickness extends to starting from the base 14 with which it came integrally and determines a shoulder 16. This tab 15 thus delimiting a passage 17 between it and the internal surface of the cap.
  • the tab 15 has a boss 18 which extends freely in a hole 19 in the shell, which passes through the latter and opens out to the outside.
  • the fastening system of the chin strap is generally known, comprising a rigid stirrup 20 around the intermediate part of which extends a loop 21 of the chin strap whose end 22 is folded down below, the branches 24 of the stirrup coming come snap elastically on the sides of the loop 11. It is understood that the stirrup 20 maintains the element 13 applied to the inner wall of the shell.
  • E1 in FIG. 1 shows the screen in the use position in which it is positively locked by closing the front opening of the helmet, in E2 the screen partially raised in the open position and in E3 , the upper edge of the screen crossing the projecting stop 5.
  • the distance A between the axis passing through the articulation points 8 of the screen and the internal surface of the latter in the middle of its upper edge, which constitutes the radius of the circle described by the screen around the axis joining its two points of articulation 8, which coincide with the holes 9, is less than the distance h which separates this axis from the top of the bead 5 at its midpoint.
  • This difference b-a is therefore approximately equal to the thickness of this bead.
  • the user can manually approach the two lateral lower edges of the screen so as to cause a widening of its upper edge allowing it to easily cross the bead 5.
  • Fig.4 shows in horizontal section the right side part of the helmet at the articulation of the screen. Clearly seen in this figure, the arrangement of the tab 15 relative to the shell and the slot formed therewith for the passage of the end of the screen E.
  • Fig.5 is a view similar to that of Fig.4 in which the screen E4 is of the flexible type molded into shape and has, at the limit of its lateral tab 6, a shoulder 26 which roughly compensates for the thickness from the outer shell of the helmet to the location where the screen penetrates, thus completing the surface of the helmet and eliminating another protrusion.
  • the helmet according to the invention is therefore completely devoid of any external projection which may present a danger to the user in the event of impacts or falls, comprises a positive locking screen which is very easily interchangeable and of fabrica tion inexpensive due to the elimination of the metal articulation members which in the helmets of the prior art had to be incorporated into the molding in the shell of the helmet.
  • the narrow slot delimited by the lug 15 of the elastic element 13 between the shell of the helmet and its inner lining cap receives the rear end of the lug 6 at each end of the screen, with friction, thus contributing to hold the screen in position, in particular in the raised position of the latter in which the extended portion 9 of the pin 6 is always engaged in the slot due to its shape: designed for this purpose.
