Description
Dispositif d'accrochage de ceinture de sécurité pour véhicule
L'invention concerne un dispositif dgaccro- chage de ceinture de sécurité pour véhicule.Seat belt hooking device for vehicle
The invention relates to a seat belt release device for a vehicle.
le dispositif de l'invention comporte une patte recevant à coulissement la sangle de la ceinture de sécurité destinée à être fixée par ses extrémités en un point haut et en un point bas de l'habitacle dVun véhicule et un dispositif de verrouillage pour la patte, ce dispositif de verrouillage étant destiné à être fixé au plancher du véhicule
Suivant une autre caractéristique de l'inven- tion, le dispositif d'accrochage est caractérisé en ce que la sangle est retenue sur la patte par un axe entouré d'un manchon cylindrique tournant librement sur cet axe
L'invention est représentée à titre d'exemple non limitatif sur les dessins ci-joints, dans lesquels
- la figure 9 est une vue en coupe d'un dis positif conforme à l'invention
- la figure 2 est une coupe suivant A=A de la figure 1
- les figures 3, 4 et 5 sont respectivement des coupes suivant B-B, C-C et D-D de la figure
La présente invention a pour but la réalisation d'un dispositif d'accrochage de ceinture de sécurité qui réduise efficaeement la violence des chocs que peut subir l'occupant d'un véhicule et notamment d'un véhicule auto- mobile.the device of the invention comprises a lug slidingly receiving the strap of the seat belt intended to be fixed by its ends at a high point and at a low point in the passenger compartment of a vehicle and a locking device for the lug, this locking device being intended to be fixed to the vehicle floor
According to another characteristic of the invention, the attachment device is characterized in that the strap is retained on the lug by an axis surrounded by a cylindrical sleeve freely rotating on this axis
The invention is shown by way of non-limiting example in the accompanying drawings, in which
- Figure 9 is a sectional view of a positive dis according to the invention
- Figure 2 is a section along A = A of Figure 1
- Figures 3, 4 and 5 are respectively sections along BB, CC and DD of the figure
The object of the present invention is to produce a seat belt fastening device which effectively reduces the violence of the shocks which the occupant of a vehicle and in particular of a motor vehicle can undergo.
Ce dispositif d'accrochage se compose d'une patte 1 et d'un dispositif de verrouillage 2 pour cette patte. Ce dispositif 2 étant destiné à être fixé par une liaison souple au plancher du véhicule alors que la patte 1 reçoit à coulissement la sangle 3 qui est fixée par ses extrémités en un point haut et en un poift bas de l'habitacle du véhicule. This attachment device consists of a lug 1 and a locking device 2 for this lug. This device 2 being intended to be fixed by a flexible connection to the floor of the vehicle while the lug 1 slidably receives the strap 3 which is fixed by its ends at a high point and at a low point in the passenger compartment of the vehicle.
Suivant l'exemple représenté, la patte 1 qui se verrouille dans le dispositif 2 présente une chape dont les deux branches 11, 12 sont reliées par un axe cylindrique 4 par exemple introduit au travers d 'un orifice correspondant de la branche 11 et se vissant par son extrémité dans l'autre branche 12 L 'amovibilité de cet axe permet la mise en place de la patte sur une sangle déjà montée sur un véhicule Il suffira pour cela d'oter la patte existant e en coupant sa traverse
Autour de cet ase 4, est disposé un manchon métallique rigide et cylindrique 5 qui tourne librement sur l'axe 4. Cette disposition a pour effet d'équilibrer les tensions s'exerçant sur la sangle entre son brin passant en oblique sur l'épaule de la personne p-rotégee et son brin disposé transversalement sur l'abdomen de cette personne. En effet, lors d'un choc, le roulement du manchon 5 sur l'axe 4 permet cet équilibrage des tensions
Cette disposition permet donc d'éviter les incorvénients des dispositifs d'accrochage connus suivant lesquels la quasi totalité du choc est supportée par le brin oblique de la sangle passant sur l'épaule de la personne protégée du fait que lors de ce choc, la sangle se bloque sans pouvoir glisser sur la patte tandis que le brin inférieur transversal reste détendu.According to the example shown, the lug 1 which locks in the device 2 has a yoke whose two branches 11, 12 are connected by a cylindrical axis 4 for example introduced through a corresponding orifice of the branch 11 and screwing by its end in the other branch 12 The removability of this axis allows the establishment of the tab on a strap already mounted on a vehicle It will suffice for this to remove the existing tab e by cutting its cross
Around this ase 4, is arranged a rigid and cylindrical metallic sleeve 5 which rotates freely on the axis 4. This arrangement has the effect of balancing the tensions exerted on the strap between its strand passing obliquely over the shoulder of the p-rotatee and its strand arranged transversely on the abdomen of this person. Indeed, during an impact, the rolling of the sleeve 5 on the axis 4 allows this balancing of the tensions
This arrangement therefore makes it possible to avoid the drawbacks of known fastening devices according to which almost all of the shock is supported by the oblique strand of the strap passing over the shoulder of the protected person because, during this shock, the strap hangs without being able to slide on the leg while the transverse lower strand remains relaxed.
La disposition conforme à l'imrentionpermet donc d'amortir la viclence du choc pendanttout le temps o, lors de ce choc, la sangle glisse sur la patte 1 en entraînant en rotation le manchon 5 et celà jusqu'à ce que les tensions du brin supérieur incliné et du brin inférieur transversal soient équilibrées. The arrangement in accordance with the requirement therefore makes it possible to dampen the viclence of the shock during all the time when, during this shock, the strap slides on the tab 1 while driving the sleeve 5 in rotation and this until the tensions of the strand upper inclined and the lower transverse strand are balanced.
Le dispositif de verrouillage 2 comporte un cylindre 6 à l'intérieur duquel se déplace un piston 7 solidaire de la tige de piston 8 dont leextrémité 89 est utilisée pour l'accrochage du dispositif sur le plancher du véhicule. The locking device 2 comprises a cylinder 6 inside which moves a piston 7 secured to the piston rod 8, the end 89 of which is used for hanging the device on the vehicle floor.
A l'intérieur du carter de ce dispositif de verrouillage, est également prévu un levier 9 pivotant sur un axe 10 qui comporte à son extrémité supérieure un rebord 11 coopérant avec une encoche 13 prévue sur la patte 1. Inside the casing of this locking device, there is also provided a lever 9 pivoting on an axis 10 which has at its upper end a flange 11 cooperating with a notch 13 provided on the tab 1.
A l'extérieur du cylindre 6, la tige de piston 8 comporte une pièce de support 12 pour une pièce 13 mobile en translation sous l'action d'un ressort 14o
Cette pièce 13 comporte à son extrémité un rebord 15 pourvu de deux ramples curvilignes et dont les extrémités 151 et 152 sont disposées de part et d'autre de l'axe d'un doigt cylindrique 16 prévu transversalement à l'extrémité inférieure du levier pivotant 9.Outside the cylinder 6, the piston rod 8 comprises a support part 12 for a part 13 movable in translation under the action of a spring 14o
This piece 13 has at its end a flange 15 provided with two curvilinear ramples and whose ends 151 and 152 are arranged on either side of the axis of a cylindrical finger 16 provided transversely to the lower end of the pivoting lever 9.
A l'intérieur du cylindre 6 est également disposé un ressort 17 qui agit sur la face inférieure du piston 7, tandis que la face supérieure de ce piston reçoit un disque rigide rectifié 18 qui forme clapet et qui à cet effet est disposé au-dessus d'un orifice qui traverse de part en part le piston 7. Inside the cylinder 6 is also arranged a spring 17 which acts on the lower face of the piston 7, while the upper face of this piston receives a rigid rectified disc 18 which forms a valve and which for this purpose is arranged above an orifice which passes right through the piston 7.
En outre la face supérieure du piston 7 comporte une rainure radiale 72 qui débouche par l'une de ses extrémités à ltextrémité de l'unique orifice et qui par son autre extrémité débouehe au-delà du disque rectifié de clapet 18. Furthermore, the upper face of the piston 7 has a radial groove 72 which opens at one of its ends to the end of the single orifice and which at its other end opens out beyond the rectified valve disc 18.
le fonctionnement de ce dispositif d'accro- chage est le suivant
Lorsqu'il s'exerce un choc sur la sangle 3, il se produit un premier amortissement du choc tant que l'équilibrage des deux brins de la sangle 3 n'est pas réalisé.the operation of this hanging device is as follows
When an impact is exerted on the strap 3, a first shock absorption occurs as long as the balancing of the two strands of the strap 3 is not achieved.
Simultanément ce choc exerce, par l'intermé- diaire de la sangle 5 et la patte 1, une traction sur le
dispositif de verrouillage auquel la patte 1 est reliée par l'intermédiaire du rebord 11 du levier 9. Cette traction provoque alors le déplacement du piston 7 à l'intérieur du cylindre 6 à l'encontre du ressort 17 etl'huile contenue dans la chambre inférieure du cylindre passe au travers de l'orifice calibré 71 vers la chambre supérieure de ce cylindre en soulevant le clapet 18
Simultanément le doigt transversal 15 vient en contact par sa rampe extérieure avec le doigt 16 et la pièce 13 se déplace dans le support 12 à l'encontre du ressort 14 jusqu'à ce que le rebord 15 ait dépassé le doigt 16.Simultaneously this shock exerts, by means of the strap 5 and the tab 1, a traction on the
locking device to which the lug 1 is connected via the flange 11 of the lever 9. This traction then causes the displacement of the piston 7 inside the cylinder 6 against the spring 17 and the oil contained in the chamber lower of the cylinder passes through the calibrated orifice 71 towards the upper chamber of this cylinder by lifting the valve 18
Simultaneously the transverse finger 15 comes into contact by its external ramp with the finger 16 and the part 13 moves in the support 12 against the spring 14 until the flange 15 has passed the finger 16.
Ce déplacement du piston 7 dans le cylindre 6 produit donc un second amortissement du choc, la valeur de cet amortissement étant fonction de la fluidité de l'huile contenue dans le cylindre et de la section du passage à section calibrée (par exemple de 6 à 7 dixièmes de millimètre) réalisé dans le piston 7. This displacement of the piston 7 in the cylinder 6 therefore produces a second damping of the shock, the value of this damping being a function of the fluidity of the oil contained in the cylinder and of the section of the passage with calibrated section (for example from 6 to 7 tenths of a millimeter) made in the piston 7.
Lorsque le choc a terminé son action, le ressort 17 tend à repousser le piston 7 et la vitesse de déplacement de ce piston est déterminée par la section calibrée de la rainure 72 par laquelle l'huile doit passer pour s'écouler depuis la chambre supérieure vers la chambre inférieure. 1a section de cette rainure 72 détermine donc une temporisation de 8 à 10 secondes pour la remontée du piston 7 dans le cylindre 6. When the shock has finished its action, the spring 17 tends to push back the piston 7 and the speed of movement of this piston is determined by the calibrated section of the groove 72 through which the oil must pass to flow from the upper chamber towards the lower chamber. The section of this groove 72 therefore determines a time delay of 8 to 10 seconds for the ascent of the piston 7 in the cylinder 6.
A la fin de ce déplacement du piston, l'extrémité supérieure 151 du rebord 15 vient en contact du doigt 16 de façon Eue sa rampe interne coopère avec ce
doigt, afin de provoquer le basculement du levier 9 qui pivote autour de l'axe 10. Ce pivotement dégage alors le rebord 11 de la poche 13 de la patte 1 ce qui provoque la libération de cette patte et assure le déverrouillage automatique de la ceinture de sécurité au bout d'un temps de temporisation déterminé par la section de la rainure
Le dispositif d'accrochage conforme à l'in- vention réalise donc bien un doux amortissement du choc, puis le déverrouillage du dispositif d'accrochage au bout d'un temps de temporisation afin que la personne protégée par la ceinture de sécurité puisse rapidement s'évacuer du véhicule accidenté sans devoir proceder manuellement au déverrouillage du dispositif d'accrochage de la ceinture. At the end of this displacement of the piston, the upper end 151 of the rim 15 comes into contact with the finger 16 so that its internal ramp cooperates with this
finger, in order to cause the lever 9 to pivot, which pivots about the axis 10. This pivoting then releases the rim 11 from the pocket 13 of the tab 1 which causes the release of this tab and ensures the automatic unlocking of the belt after a time delay determined by the section of the groove
The attachment device according to the invention therefore achieves a gentle shock absorption, then unlocking the attachment device after a time delay so that the person protected by the seat belt can quickly s '' Evacuate from the accident vehicle without having to manually unlock the seat belt hooking device.
