Description
La présente invention concerne un dispositif de déviation d'une sangle de ceinture de sécurité en sortie d'un enrouleur pour passager arrière d'un véhicule automobile. The present invention relates to a device for deflecting a seat belt strap at the outlet of a retractor for a rear passenger of a motor vehicle.
Elle s'applique notamment au type d'enrouleur qui fixé sur une tablette située en arrière siège arrière correspondant du véhicule. It applies in particular to the type of reel which fixed on a shelf located behind the corresponding rear seat of the vehicle.
Les dispositifs actuels de renvoi de la sangle de ceinture de sécurité ne permettent pas de tenir compte de toute position relative du passager sur son siege ayant bouclé la ceinture, de sorte que l'enroulement ou le deroulement de la sangle s'effectue souvent dans de mauvaises conditions pouvant occasionner un ' fonctionnement de l'enrouleur, tel que par exemple un mauvais fonctionnement de celui-ci en cas de choc. Current devices for returning the seat belt strap do not take account of any relative position of the passenger in his seat having fastened the belt, so that the winding or unwinding of the strap is often carried out in poor conditions which may cause the reel to function, such as for example a malfunction of the latter in the event of an impact.
La présente invention a pour but 'éliminer 1 inconvénient ci-dessus des dispositifs connus en proposant un dispositif de déviation d'une sangle de ceinture de sécurité en sortie d'un enrouleur pour passager arrière d'un véhicule automobile, où 1 enrouleur fixé sur une tablette en arrière du siège arrière et est caractérisé en ce qu'il comprend un disque de renvoi comportant une ouverture de passage de la sangle une bague de support du disque de renvoi montée pivotante autour d'un axe approximativement vertical de façon que le disque de renvoi et la bague support puissent pivoter autour de cet axe lors de débattements de la sangle. The aim of the present invention is to eliminate the above drawback of known devices by proposing a device for deflecting a seat belt strap at the outlet of a retractor for the rear passenger of a motor vehicle, where 1 retractor fixed on a shelf behind the rear seat and is characterized in that it comprises a deflection disc having an opening for the passage of the strap a deflection disc support ring pivotally mounted about an approximately vertical axis so that the disc deflection and the support ring can pivot around this axis during movement of the strap.
Le disque de renvoi est monté à rotation dans la bague de support autour de son axe central transversal de façon à suivre les déplacements de la sangle provoquant rotation du disque autour de cet axe. The return disc is rotatably mounted in the support ring around its transverse central axis so as to follow the movements of the strap causing rotation of the disc around this axis.
De préférence, l'ouverture de passage de la sangle rectangulaire. Preferably, the opening for passage of the rectangular strap.
La bague de support est montée dans un boîtier fixe comporte deux axes de pivotement diamétralement opposés montés tourillonnant dans le boîtier fixe. Avantageusement, le boîtier de support de la bague est celui de l'enrouleur. The support ring is mounted in a fixed housing has two diametrically opposite pivot axes mounted journalling in the fixed housing. Advantageously, the ring support box is that of the reel.

The invention will be better understood and other objects, characteristics, details and advantages thereof will appear more clearly in the explanatory description which follows, made with reference to the appended drawings given solely by way of example illustrating an embodiment of the invention. and in which - Figure 1 is a side view of a rear seat of a motor vehicle showing the seat belt strap deflection device according to the invention; - Figure 2 is an enlarged view of the part circled in of Figure 1; - Figure 3 is an enlarged perspective view of the deflection device of the seat belt strap according to the invention; - Figure 4 is a side view similar to that of Figure 1 and showing the strap having a different offset than that of Figure 1; and - Figure 5 is an enlarged view of the V-ringed part of Figure 4.
En se reportant aux figures, la référence 1 désigne un siège arrière de véhicule automobile sur lequel est assis un passager ayant bouclé sa sangle 2 ceinture de sécurité comprenant traditionnellement une partie thoracique passant par l'une des épaules passager et une partie ventrale. Referring to the figures, the reference 1 designates a rear seat of a motor vehicle on which sits a passenger who has fastened his strap 2 seat belt traditionally comprising a thoracic part passing through one of the passenger shoulders and a ventral part.
La sangle 2 sort d'un enrouleur logé dans un boîtier 3 solidaire d'une tablette horizontale 4 située en arrière du dossier arrière du siège 1. The strap 2 comes out of a reel housed in a box 3 secured to a horizontal shelf 4 located behind the rear seat backrest 1.
Selon l'invention, un dispositif de déviation est prévu entre le boîtier de l'enrouleur 3 et dossier du siège 1 et est agencé de façon à tenir compte des différents débattements et déplacements de sangle 2 lors de mouvements plus ou moins importants du passager sur son siège. Ce dispositif comprend un disque rigide renvoi 5 comportant une ouverture rectangulaire ou sensiblement rectangulaire 6 de passage de la sangle 2 une bague annulaire 7 de support du disque de renvoi 5 montée pivotante autour d'un axe approximativement vertical Z-Z' dans un boîtier 8 fixé sur la tablette 4 à proximité de la sortie du boîtier de l'enrouleur 3. L ouverture 6 peut s'étendre suivant une corde du disque ou, en variante suivant un diamètre de celui-ci. According to the invention, a deflection device is provided between the housing of the reel 3 and the seat back 1 and is arranged so as to take into account the different movements and movements of the strap 2 during more or less significant movements of the passenger on his seat. This device comprises a rigid return disc 5 comprising a rectangular or substantially rectangular opening 6 for the passage of the strap 2 an annular ring 7 for supporting the return disc 5 pivotally mounted around an approximately vertical axis ZZ 'in a housing 8 fixed on the tablet 4 near the outlet of the reel housing 3. The opening 6 may extend along a cord of the disc or, as a variant, according to a diameter of the latter.
La bague de support 7 comporte deux axes de pivotement 9 diamétralement opposés faisant saillie extérieurement et montés tourillonnant dans le boîtier de support 8. Les deux axes de pivotement 9 peuvent être montés a rotation respectivement au travers de deux plaques parallèles horizontales supérieure et inférieure 10 amoviblement fixées au boîtier 8 par vis de fixation symbolisées en 11 d'une plaque 12 solidaire de chaque plaque 10 perpendiculairement à lé-ci et s'étendant dans un plan vertical parallèle à l'axe longitudinal du véhicule. The support ring 7 comprises two pivot axes 9 diametrically opposite projecting outwardly and mounted journalling in the support housing 8. The two pivot axes 9 can be rotatably mounted respectively through two parallel upper and lower horizontal plates 10 removably fixed to the housing 8 by fixing screws symbolized at 11 from a plate 12 secured to each plate 10 perpendicular to it and extending in a vertical plane parallel to the longitudinal axis of the vehicle.
Le disque de renvoi 5 est monté à rotation dans la bague de support 7 autour de son axe central géométrie X-X' en étant coplanaire à la bague 7. A cet effet, la bague de support 7 peut comporter une collerette radialement interne s'engageant dans une gorge périphérique du disque 5 ou réciproquement. The deflection disc 5 is rotatably mounted in the support ring 7 around its central axis geometry XX 'while being coplanar with the ring 7. For this purpose, the support ring 7 may include a radially internal flange engaging in a peripheral groove of the disc 5 or vice versa.
Lorsque le passager bouge sur son siège façon à déplacer par son épaule la sangle 2 dans une direction approximativement horizontale en sortie du bol ier de l'enrouleur 3, la portion de sangle traversant l'ouverture 6 du disque de renvoi 5 provoque le pivotement autour de l'axe Z-Z' de la bague support 7 et du disque de renvoi 5. When the passenger moves in his seat so as to move the strap 2 by his shoulder in an approximately horizontal direction at the outlet of the reel bowl 3, the portion of strap passing through the opening 6 of the return disc 5 causes the pivoting around of the axis ZZ 'of the support ring 7 and of the return disc 5.
Lors de mouvement du passager tendant a provoquer une torsion de la sangle 2 en sortie du boîtier enrouleur 3, cette torsion impartit une rotation du disque de renvoi 5 relativement à la bague de support 7 dans le sens correspondant comme représenté en figure 5 relativement à la figure 2. During movement of the passenger tending to cause a twist of the strap 2 at the outlet of the rewinder housing 3, this twist impart a rotation of the return disc 5 relative to the support ring 7 in the corresponding direction as shown in FIG. figure 2.
Bien entendu, la sangle 2 peut subir à la fois une torsion et un débattement combinés provoquant le pivotement de la bague de support 7 et la rotation du disque de renvoi 5 autour respectivement des axes Z-Z' et X- '. Of course, the strap 2 can undergo both a combined torsion and a deflection causing the pivoting of the support ring 7 and the rotation of the return disc 5 around the axes Z-Z 'and X-' respectively.
Selon une variante de réalisation, l'ensemble constitué par la bague de support 7 et le disque de renvoi 5 peut être intégré au boîtier de l'enrouleur 5 c' -à-dire que le boîtier 8 et le boîtier l'enrouleur 3 forment un boîtier unique. According to an alternative embodiment, the assembly constituted by the support ring 7 and the deflection disc 5 can be integrated into the housing of the reel 5, that is to say that the box 8 and the housing the reel 3 form a unique housing.
Le dispositif de déviation ci-dessus décrit l'invention permet un déroulement ou un enroulement correct de la sangle de ceinture de sécurité quelle soit la position du passager, sans aucun problème de disfonctionnement, même en cas de choc.The above-described deflection device of the invention enables the seat belt strap to be unwound or wound correctly whatever the passenger's position, without any problem of malfunction, even in the event of an impact.
