DISPOSITIF D'ANCRAGE D'UNE CEINTURE DE SECURITE DE
SIEGE MOBILE SUR LE PLANCHER D'UN VéHICULE AUTOMOBILE
L'invention concerne un dispositif d'ancrage d'une ceinture de sécurité de siège mobile sur le plancher d'un véhicule automobile.ANCHORING DEVICE FOR A SEAT BELT
MOBILE SEAT ON THE FLOOR OF A MOTOR VEHICLE
The invention relates to a device for anchoring a mobile seat safety belt to the floor of a motor vehicle.
L'invention concerne plus particulièrement un dispositif d'ancrage d'une ceinture de sécurité d'une banquette carrière, dans lequel le point d'accrochage de la ceinture qui se trouve au voisinage du plan longitudinal médian du véhicule, est porté par un élément monté mobile avec le siège et peut être relié à un élément de structure fixé sur le plancher.The invention relates more particularly to a device for anchoring a seat belt of a career bench seat, in which the point of attachment of the belt which is located in the vicinity of the median longitudinal plane of the vehicle, is carried by an element mounted mobile with the seat and can be connected to a structural element fixed to the floor.
La publication FR-R 2 422 528 décrit un dispositif d'ancrage conforme au préambule de la revendication.The publication FR-R 2 422 528 describes an anchoring device in accordance with the preamble of the claim.
Lorsque l'effort de traction sur l'ancrage est appliqué dans une zone insuffisamment renforcée du plancher, la déformation résultante du plancher est incompatible avec la qualité de rétention exigée de la ceinture de sécurité.When the tensile force on the anchor is applied in an insufficiently reinforced area of the floor, the resulting deformation of the floor is incompatible with the quality of retention required of the seat belt.
Par contre, lorsque l'effort de traction sur l'ancrage est communiqué à une traverse de renforcement du plancher, cette dernière subit une contrainte de flexion inadmissible.On the other hand, when the tensile force on the anchor is communicated to a reinforcement cross member of the floor, the latter undergoes an unacceptable bending stress.
La présente invention apporte une solution a ce problème.The present invention provides a solution to this problem.
D'autres caractéristiques et avantages de l'invention apparaîtront à la lecture de la description qui suit, d'un exemple de réalisation du dispositif en référence au dessin annexé dans lequel - la figure l est une vue en perspective de
l'ensemble du dispositif associé à une banquette
arrière de véhicule automobile, - la figure 2 est une vue en coupe transversale du
dispositif par le plan longitudinal médian du
véhicule, - la figure 3 est un diagramme représentatif des
efforts en fonction des déplacements du dispositif
d'ancrage.Other characteristics and advantages of the invention will appear on reading the description which follows, of an embodiment of the device with reference to the appended drawing in which - FIG. 1 is a perspective view of
the entire system associated with a bench
rear of a motor vehicle, - Figure 2 is a cross-sectional view of the
device by the median longitudinal plane of the
vehicle, - Figure 3 is a representative diagram of
forces as a function of the movements of the device
anchor.
Ru dessin, on voit un siège repliable 20 dans lequel l'assise l est montée mobile en translation le long de glissières 3 solidaires du plancher 10 du véhicule automobile.Ru drawing, we see a folding seat 20 in which the seat l is mounted movable in translation along slides 3 secured to the floor 10 of the motor vehicle.
Le dossier 4 est monté, à titre d'exemple, rabattable sur l'assise l par pivotement autour d'un axe 5 relié à l'assise l et disposé a la base du dossier 4. Le mouvement de rabattement du dossier 4 s'opère par suite du déclenchement d'une serrure de liaison 6 qui fixe le dossier 4 a un élément de structure 61 du véhicule.Le siège 20, qui peut store réalisé sous la forme d'une banquette, est muni d'un crochet mobile 7 solidaire de l'assise l, tel que décrit à titre d'exemple dans la publication FR-A 2 566 347
Le crochet mobile 7 porte l'axe de rotation 8 de deux supports 9a, 9b, orientés vers la surface de l'assise l, auxquels sont respectivement reliés des points d'accrochage 11 constituant des boîtiers de réception de pênes de verrouillage 12a, 12b montés sur les sangles, thoracique et de bassin, des ceintures de sécurité 13a, 13b ainsi que cela est bien connu.The backrest 4 is mounted, for example, foldable on the seat l by pivoting about an axis 5 connected to the seat l and arranged at the base of the backrest 4. The movement of the backrest folds down 4 s' operates as a result of the triggering of a link lock 6 which fixes the backrest 4 to a structural element 61 of the vehicle. The seat 20, which can be made in the form of a bench seat, is provided with a movable hook 7 secured to the seat l, as described by way of example in publication FR-A 2,566,347
The movable hook 7 carries the axis of rotation 8 of two supports 9a, 9b, oriented towards the surface of the seat l, to which are respectively attached attachment points 11 constituting boxes for receiving locking bolts 12a, 12b mounted on the straps, thoracic and pelvis, seat belts 13a, 13b as is well known.
te plancher 10 porte un renfort soudé 15.te floor 10 carries a welded reinforcement 15.
Le renfort 15 constitue également la paroi de fermeture d'une traverse 16 soudée sur le renfort 15.The reinforcement 15 also constitutes the closing wall of a crosspiece 16 welded to the reinforcement 15.
Le plancher 10 possède, par ailleurs, une ouverture de montage 17 d'un élément de structure 18 rapporté au moyen de boulons 21 sur le renfort 15.The floor 10 also has a mounting opening 17 of a structural element 18 added by means of bolts 21 on the reinforcement 15.
Ainsi que cela est représenté sur le dessin, l'élément de structure 18 est constitué par un profil en U dont
les ailes 18a sont entretoisées par des barreaux d'ancrage 19 du crochet 7 porté par le siège.As shown in the drawing, the structural element 18 is constituted by a U-shaped profile,
the wings 18a are braced by anchor bars 19 of the hook 7 carried by the seat.
Selon l'invention, les boulons de fixation 21 assurent
la retenue d'un lien souple 23 inextensible en forme de boucle 24 engagée sous un étrier 25 soudé à la
traverse 26 de suspension de l'essieu arrière du véhicule.According to the invention, the fixing bolts 21 provide
the retention of a flexible link 23 inextensible in the form of a loop 24 engaged under a stirrup 25 welded to the
cross member 26 for suspension of the rear axle of the vehicle.
titre d'exemple, le lien 23 est constitué par une
sangle dont la longueur autorise les variations de hauteur de la travese 26 sans exercer de tension sur
l'étrier 25 ou sur la traverse 26.As an example, link 23 is made up of a
strap whose length allows variations in the height of the span 26 without exerting tension on
the bracket 25 or on the crosspiece 26.
Sans sortir du cadre de l'invention, le lien 23 pourra
tout aussi bien store réalisé sous la forme d'un câble
ou d'un élément de tale. Without departing from the scope of the invention, the link 23 may
just as well blind made in the form of a cable
or a tale element.
Le diagramme de la figure 3 montre qu'une traction sur le lien 23 consécutive à un effort appliqué F sur le crochet 7 a pour effet de raidir la liaison 18 a partir d'un seuil d'effort F1 après une déformation initiale Z1. Lorsque la traverse 26 est en butée de choc, la liaison oppose une résistance à la déformation et l'effort F peut croltre sans inconvénient jusqu'a sa valeur de seuil supérieur FR sans que la déformation du plancher n'atteigne une valeur telle que ZR.The diagram in FIG. 3 shows that traction on the link 23 following a force applied F on the hook 7 has the effect of stiffening the link 18 from a force threshold F1 after an initial deformation Z1. When the cross member 26 is in shock abutment, the connection provides resistance to deformation and the force F can increase without inconvenience up to its upper threshold value FR without the deformation of the floor reaching a value such as ZR .
Par contre, en l'absence du lien 23, le seuil d'effort
F2 inférieur à FR peut engendrer une déformation ZR du plancher. On the other hand, in the absence of link 23, the effort threshold
F2 lower than FR can cause deformation ZR of the floor.
