Abstract
Description
La présente invention concerne un dispositif de tension pour ceintures de sécurité permettant une meilleure tolérance de celles-ci par les usagers. The present invention relates to a tensioning device for seat belts allowing better tolerance of the latter by users.
En effet, le port des ceintures de sécurité peut entrarner de nombreuses gênes. Un conducteur ou un passager de petite taille peut être g8né par la ceinture qui passe au niveau du cou. Au contraire, une personne de grande taille peut être gênée au niveau du bras. In fact, wearing seat belts can cause many discomforts. A small driver or passenger may be hampered by the belt which passes at neck level. On the contrary, a tall person can be embarrassed on the arm.
Une ceinture de sécurité équipée du dispositif faisant l'objet de la présente invention supprime cette sensation d'oppression sur le cou et sur la cage thoracique. Par ailleurs, une ceinture de sécurité frottant fortement et de manière régulière sur les vêtements provoque un lustrage de ceux-ci. A seat belt fitted with the device which is the subject of the present invention eliminates this feeling of oppression on the neck and on the rib cage. In addition, a seat belt rubbing strongly and regularly on the clothes causes them to shine.
les deux inconvénients cités plus haut, à savoir oppression de la cage thoracique, gêne au niveau du cou et lustrage des vêtements n'incitent pas les automobilistes et leurs passagers au port de la ceinture de sécurité. the two disadvantages mentioned above, namely oppression of the rib cage, discomfort at the level of the neck and polishing of the clothes do not encourage motorists and their passengers to wear a seat belt.
Ces inconvénients sont supprimés gracie à l'installation du dispositif faisant ltobjet de la présente invention. These drawbacks are eliminated thanks to the installation of the device forming the object of the present invention.
Ce dispositif est placé sur la partie de la carrosserie où se trouve l'enrouleur de la ceinture de sécurité et entre l'anneau-potence'où coulisse celle-ci. This device is placed on the part of the bodywork where the seat belt retractor is located and between the stem ring where it slides.
Il eomporte un boîtier I dans lequel monte et descend un rouleau 3 avec un axe 2. Ce rouleau 3 se trouve libre quand il est tiré vers le haut (position I9 - Fig. 3/3) permettant ainsi d'accrocher la ceinture IO. En relâchant lentement la ceinture IO, le rouleau 3 prend la position intermédiaire (position arrêt I4 - Fig. 3/3) et se trouve bloqué à la position souhaitée, grâce à deux encoches I3 se trouvant sur les guides 4 de roulement du rouleau 3. It has a housing I in which a roller 3 with an axis 2 is raised and lowered. This roller 3 is free when it is pulled upwards (position I9 - Fig. 3/3) thus allowing the belt IO to be hung. By slowly releasing the belt IO, the roller 3 takes the intermediate position (stop position I4 - Fig. 3/3) and is locked in the desired position, thanks to two notches I3 located on the rolling guides 4 of the roller 3 .
Pour libérer le rouleau 3 des encoches I3, on tire la ceinture 10 vers le haut. Le rouleau 3 monte en position supérieure I9. Le ressort de l'enrouleur étant en pleine tension, on lace la ceinture 10 et le rouleau 3 franchit les encoches 13 pour venir en position libre inférieure I5, ce qui permet à la ceinture de se loger dans l'enrouleur. To release the roller 3 from the notches I3, the belt 10 is pulled upwards. The roller 3 rises to the upper position I9. The spring of the reel being in full tension, the belt 10 is lace and the roller 3 crosses the notches 13 to come into the lower free position I5, which allows the belt to be housed in the reel.
En cas de choc violent, le rouleau 3 passe à la position supérieure I9 en libérant la ceinture 10 qui se trouve normalement bloquée dans l'enrouleur. In the event of a violent impact, the roller 3 passes to the upper position I9 by releasing the belt 10 which is normally blocked in the reel.
Le dispositif faisant l'objet de la présente invention peut être réalisé en métal coulé ou formé ou en matière plastique par formage ou injection. The device which is the subject of the present invention can be made of cast or formed metal or of plastic by forming or injection.
Le rouleau 3 est réalisé de préférence en acier et l'axe 2 de celui-ci en bronze de manière à éviter tout grippage. The roller 3 is preferably made of steel and the axis 2 thereof in bronze so as to avoid any seizure.
Le boîtier I renfermant le rouleau 3 est fermé par un couvercle 8 grâce à quatre vis 9 avec rondelles élastique IÇ. I1 suffit d'enlever le couvercle 8 pour insérer la ceinture 10 et remettre le couvercle 8 fermé par les quatre vis 9. The housing I containing the roller 3 is closed by a cover 8 by means of four screws 9 with elastic washers IÇ. It suffices to remove the cover 8 to insert the belt 10 and replace the cover 8 closed by the four screws 9.
Le boîtier I renfermant le dispositif se fixe par deux vis 5 sur le montant vertical de la carrosserke, entre l'anneau coulissant supérieur et l'entrée de l'enrouleur. The box I containing the device is fixed by two screws 5 on the vertical upright of the coachwork, between the upper sliding ring and the inlet of the reel.
Le boiter I présente deux trous I7 de 5mm de diamètre pour lepassage de deux vis Parker 5 pour fixation au montant du véhicule. Il est positionné dans l'alignement de la ceinture 10 à quelques centimètres au-dessus de l'en- rouleur. The box I has two I7 holes of 5mm in diameter for the passage of two Parker 5 screws for attachment to the vehicle upright. It is positioned in line with the belt 10 a few centimeters above the winder.
Les quatre vis 9 serrant le couvercle 8 avec rondelles élastique I6 permettent un réglage suivant serrage pour adapter le dispositif aux différentes épaisseurs des ceintures allant en général de I2/IOème à I8/IOème selon les modèles.The four screws 9 tightening the cover 8 with elastic washers I6 allow adjustment according to tightening to adapt the device to the different thicknesses of the belts generally going from I2 / IOème to I8 / IOème according to the models.
Le boftier I présente deux fentes latérales 4, guides de l'axe 2 du rouleau 3. Ces fentes 4 ayant la largeur du diamètre de l'axe 2 du rouleau 3 sont réalisées en arc de cercle d'un rayon de 250mm et po'sition- nées face à face sur les parties latérales longitudinales du boîtier. Sur le centre ce ces fentes 4 se trouvent deux encoches I3 stabilisant le rouleau 3 sur le petit rayon vers la partie la plustproche du couvercle 8. La fente 4 en forme d'arc de cercle permet au rouleau 3 de se bloquer au cèntre (position arrêt I4 - Fig. 3/3) et de se libérer aux extrémités (positions I9 et 15 - Fig. 3/3). The boftier I has two lateral slots 4, guides of the axis 2 of the roller 3. These slots 4 having the width of the diameter of the axis 2 of the roller 3 are produced in an arc of a circle with a radius of 250mm and po ' located face to face on the longitudinal side parts of the housing. In the center of these slots 4 are two notches I3 stabilizing the roller 3 on the small radius towards the closest part of the cover 8. The slot 4 in the form of an arc of a circle allows the roller 3 to be blocked in the center (position stop I4 - Fig. 3/3) and release at the ends (positions I9 and 15 - Fig. 3/3).
La partie inférieure latérale du boîtier I est percée de quatre trous I7 pour le passage des axes 7 et 6 pour les rouleaux I2 et II. Ce rouleau II, de 8mm est percé d'un trou pour l'axe 6 de 4,5mm excentré de façon à ce que lorsqu'on tire sur la ceinture IO pour faire monter le rouleau 3, l'excentricité du rouleau II rapproche la ceinture du rouleau 3. Quand on décrocbe la ceinture IO, le rouleau 3 se trouve libéré de l'appui de la ceinture afin de ne pas gêner l'enroulement de la ceinture sur l'enrouleur.Le rouleau I2 avec un zxe 7 facilite le déplacement de la ceinture IO en supprimant le frottement sur le couvercle 8 du bottier I. Pour libérer des encoches I3 le rouleau 3, il faut tirer sur la ceinture IO afin de donner le maximum de puissance au ressort de l'enrouleur et licher la ceinture IO. Le rouleau 3 reviendra à sa position libre I5 en franchissant les encoches I3. The lower lateral part of the housing I is pierced with four holes I7 for the passage of the axes 7 and 6 for the rollers I2 and II. This roller II, of 8mm is pierced with a hole for the axis 6 of 4.5mm eccentric so that when one pulls on the belt IO to raise the roller 3, the eccentricity of the roller II brings the belt of the roller 3. When the belt IO is unhooked, the roller 3 is released from the support of the belt so as not to hinder the winding of the belt on the reel. The roller I2 with a zxe 7 facilitates the displacement of the belt IO by eliminating the friction on the cover 8 of the bootmaker I. To release the notches I3 the roller 3, it is necessary to pull on the belt IO in order to give the maximum power to the spring of the reel and loosen the belt IO. The roller 3 will return to its free position I5 by crossing the notches I3.
Le dispositif faisant l'objet de la présente description, s'adapte à tous les modèles de ceintures de sécurité. I1 permet de stabiliser la ceinture par simple traction sur celle-ci, à l'aide d'une seule main, ne compromettant pas ainsi la conduite et donc la sécurité du conducteur et des passagers. The device which is the subject of this description adapts to all models of seat belts. I1 makes it possible to stabilize the belt by simple pulling on it, using one hand, thus not compromising driving and therefore the safety of the driver and passengers.
Ce dispositif a pour avantage entre mis en place facilement et rapidement, sans démontage de la ceinture de sécurité. The advantage of this device is that it is quickly and easily put in place without removing the seat belt.
Ce dispositif favorise l'utilisation de la ceinture de sécurité gracie à la facilité du bouclage. La tension de la ceinture étant obtenue très facilement après bouclage, par simple traction sur celle-ci, ce qui supprime une gêne mal supportée par les utilisateurs.
