Abstract
Description
L'objet de l'invention concerne un premier certificat d'addition au brevet français NO 83 13 579 déposé le 19 Août 1983, pour dispositif d'assujettissement pour casque de protection pour motocyclistes et similaires. The subject of the invention relates to a first certificate of addition to French patent NO 83 13 579 filed on August 19, 1983, for securing device for protective helmet for motorcyclists and the like.
II consiste en des perfectionnements apportés au dispositif de rétention et à leur réglage dans les plans transversaux ou latéraux. It consists of improvements made to the retention device and to their adjustment in the transverse or lateral planes.
L ' expérience a démontré que le bon positionnement du casque sur la tête et sa stabilité, qui sont des facteurs importants de confort et de sécurité pouvaient être très sensiblement améliorés par des réglages permettant l'adaptation à la morphologie de l'usager. Experience has shown that the good positioning of the helmet on the head and its stability, which are important factors of comfort and safety, can be very significantly improved by adjustments allowing adaptation to the morphology of the user.
Le dispositif suivant l'invention permet de supprimer ces inconvénients et d'assurer le réglage de la jugulaire et de l'arceau cerclant la nuque avec les éléments d'assujettissement latéral des garnitures contactant les faces opposées du cou afin de réaliser un cerclage sans jeu adapté à la morphologie du porteur le tout rendant le casque inarrachable
I1 est constitué par la combinaison du blocage des points de pivotement mobile du dispositif de rétention de la jugulaire et de l'arceau arrière avec 11 ajustement latéral des garnitures contactant le cou.The device according to the invention makes it possible to eliminate these drawbacks and to ensure the adjustment of the chin strap and the hoop encircling the nape with the lateral securing elements of the linings contacting the opposite faces of the neck in order to achieve a hooping without play. adapted to the morphology of the wearer, all making the helmet unbreakable
It is constituted by the combination of the locking of the mobile pivot points of the chin strap retention device and the rear arch with the lateral adjustment of the fittings contacting the neck.
Sur les dessins annexés, donnés à titre d'exemple non limitatif, d'une des formes de réalisation de l'objet de I ' invention
La figure 1 est une vue en élévation du dispositif de rétention.In the accompanying drawings, given by way of nonlimiting example, of one of the embodiments of the subject of the invention
Figure 1 is an elevational view of the retention device.
Les figures 2 et 3 représentent vu en élévation et en coupe le dispositif d'assujettissement latéral. Figures 2 and 3 show in elevation and in section the lateral securing device.
L ' ensemble du dispositif de rétention, figure 1, est autonome en ce qui concerne l'assemblage de ses éléments et n'est solidaire de la coque du casque qu'en deux points de pivotement symétriques. The entire retention device, Figure 1, is autonomous with regard to the assembly of its elements and is secured to the helmet shell only in two symmetrical pivot points.
Le léger déplacement angulaire possible permet de positionner avec précision par rapport à la coque, le dispositif de rétention qui peut épouser intimement l'embase de la tête. Le blocage des points de pivotement étant taré pour un couple déterminé, un très léger déplacement angulaire du dispositif de rétention vis-à-vis de la coque est possible sous l'action d'un impact, ce qui peut éviter un traumatisme du cou, ce que ne pouvait réaliser le dispositif décrit sur le brevet principal. Les deux pivots 3 de la jugulaire et les deux pivots 4 de 1' arceau arrière ne sont plus solidaires de la coque, mais sont montés sur les deux platines 21 placées symétriquement à l'intérieur de la coque. Ces platines peuvent osciller d ' un angle réduit autour de l'axe ou pivot 22 monté sur la paroi du casque. The slight angular displacement possible makes it possible to precisely position the retention device relative to the shell, which can closely fit the base of the head. The locking of the pivot points being tared for a determined torque, a very slight angular displacement of the retention device with respect to the shell is possible under the action of an impact, which can avoid trauma to the neck, what could not achieve the device described on the main patent. The two pivots 3 of the chin strap and the two pivots 4 of the rear arch are no longer integral with the hull, but are mounted on the two plates 21 placed symmetrically inside the hull. These plates can oscillate at a reduced angle around the axis or pivot 22 mounted on the wall of the helmet.
Le dispositif de verrouillage dans les deux sens reste inchangé, le secteur denté étant solidaire de la platine 21 , le pivot 22 comporte un dispositif de blocage formé par une rondelle crantée 23 solidaire de la coque 20 et une contrepartie 24 solidaire de la platine 21, le tout étant bloqué par une vis 25 permettant le réglage angulaire et le blocage en position de l'en- semble du dispositif de rétention. The locking device in both directions remains unchanged, the toothed sector being secured to the plate 21, the pivot 22 includes a locking device formed by a notched washer 23 secured to the shell 20 and a counterpart 24 secured to the plate 21, the whole being blocked by a screw 25 allowing the angular adjustment and the blocking in position of the assembly of the retention device.
Ce blocage comporte également une rondelle élastique tarée 26 à fonction de limiteur de couple.. This blocking also includes a calibrated elastic washer 26 with a torque limiter function.
Le dispositif combiné de rétention, figures 2, 3, permet simultanément d ' ajuster le dispositif de rétention suivant un diamétre perpendiculaire au plan médian afin d'assurer un meilleur assujettissement du casque sur toute la périphérie du cou empêchant un déchaussement accidentel avec ajustement à plusieurs tailles de tête. The combined retention device, FIGS. 2, 3, simultaneously makes it possible to adjust the retention device according to a diameter perpendicular to the median plane in order to ensure better securing of the helmet over the entire periphery of the neck preventing accidental loosening with adjustment to several head sizes.
A cet effet, la jugulaire pivotante 1 et l'arceau arrière 2 décrits sur le brevet principal comportent chacun intérieurement et de chaque côté un bossage en forme de coin 27, qui lors du pivotement de 1 et 2 dans le sens de la fermeture viennent s ' introduire sous la plaque 25 qui fléchit et vient prendre la position hachurée, fig 2, entraînant dans son déplacement l'élément amortisseur 28 qui adhére à la pièce 26. To this end, the pivoting chin strap 1 and the rear arch 2 described on the main patent each have internally and on each side a wedge-shaped boss 27, which during the pivoting of 1 and 2 in the closing direction come s 'introduce under the plate 25 which flexes and comes to take the hatched position, fig 2, causing in its movement the damping element 28 which adheres to the part 26.
La déformation se produit exclusivement sur les pièces 26 et 28, car la jugulaire 1 et l'arceau 2 qui sont rigides prennent appui sur la coque 20 fermee et également rigide. The deformation occurs exclusively on the parts 26 and 28, because the chin strap 1 and the arch 2 which are rigid bear on the shell 20 closed and also rigid.
L'ajustement latéral ne se limite pas autour du cou, mais remonte d'une façon dégressive jusqu'au niveau des points
de pivotement. Toute la partie basse de la tête se trouve ainsi
concernée. Le crâne est parfaitement calé dans le fond du casque
ce qui assure la stabilité et améliore le confort.The lateral adjustment is not limited around the neck, but goes up gradually to the point level
pivot. The whole lower part of the head is thus
concerned. The skull is perfectly seated in the bottom of the helmet
which provides stability and improves comfort.
Le casque tel qu'il est décrit sur le brevet principal
est stabilisé et sa fonction amortisseuse est améliorée quels que
soient les chocs reçus et leurs orientations.The helmet as described on the main patent
is stabilized and its damping function is improved whatever
be the shocks received and their orientations.
Toutefois les formes, dimensions et dispositions des
différents éléments pourront varier dans la limite des équivalents
comme d'ailleurs les matières utilisées pour leur fabrication,
sans changer pour cela, la conception générale de l'invention
qui vient d'être décrite. However the forms, dimensions and arrangements of
different elements may vary within the limit of equivalents
like the materials used for their manufacture,
without changing for that, the general conception of the invention
which has just been described.
