Description

DISPOSITIF D'ANCRAGE D'UNE CEINTURE DE SECURITE SUR
UN SIEGE DE VéHICULE AUTOMOBILE
L'invention concerne un dispositif d'ancrage d'une ceinture de sécurité sur un siège de véhicule automobile.DEVICE FOR ANCHORING A SEAT BELT ON
A MOTOR VEHICLE SEAT
The invention relates to a device for anchoring a seat belt to a seat of a motor vehicle.

L'invention concerne plus précisément un dispositif d'ancrage d'une ceinture de sécurité dans lequel un moyen connecteur coulissant qui forme la transition entre une sangle thoracique et une sangle abdominale est relié à un ancrage latéral situé à la partie inférieure du dossier articulé sur le support de l'assise, autour d'un axe situé au-dessus dudit ancrage.The invention relates more precisely to a device for anchoring a seat belt in which a sliding connector means which forms the transition between a chest strap and a abdominal strap is connected to a lateral anchor located at the lower part of the articulated backrest on the seat support, around an axis located above said anchor.

La publication FR-A-2101292 décrit un dispositif d'ancrage appliqué à un siège dont le dossier est articulé autour d'un axe situé au-dessus de l'ancrage latéral de la boucle de verrouillage de la ceinture de sécurité.The publication FR-A-2101292 describes an anchoring device applied to a seat, the back of which is articulated around an axis situated above the lateral anchoring of the locking buckle of the seat belt.

Les ancrages de ce type améliorent la retenue de l'occupant du siège en réduisant les déplacements du corps au cours d'une collision. Lorsque le dossier occupe une position sensiblement verticale, ces ancrages permettent en outre à la ceinture de prendre un appui correct sur les os du bassin et d'éviter lors d'une collision les lésions internes dues à une compression exagérée de l'abdomen.Anchorages of this type improve the restraint of the seat occupant by reducing the movement of the body during a collision. When the backrest occupies a substantially vertical position, these anchors also allow the belt to take proper support on the pelvic bones and avoid internal injuries due to exaggerated compression of the abdomen during a collision.

Par contre lorsque le siège du véhicule est équipé d'un dossier inclinable susceptible de conférer à l'occupant du siège une position de buste inclinée vers l'arrière, le basculement antéro-postérieur du bassin ne permet plus à la ceinture de rester en appui sur les os du bassin.On the other hand, when the vehicle seat is equipped with a reclining backrest capable of conferring on the seat occupant a bust position inclined towards the rear, the anteroposterior tilting of the pelvis no longer allows the belt to remain in support on the pelvic bones.

L'invention a principalement pour objet un dispositif d'ancrage d'une ceinture de sécurité du type prédéfmi dans lequel les ancrages latéraux inférieurs de la sangle abdominale sont positionnés automatiquement, dans le but de maintenir l'appui de la sangle sur le bassin de l'occupant du siège, au cours de l'inclinaison de son buste vers l'arrière, à la suite d'une modification de la position angulaire du dossier.The main object of the invention is a device for anchoring a seat belt of the pre-defined type in which the lower lateral anchorages of the abdominal strap are positioned automatically, in order to maintain the support of the strap on the pelvis. the occupant of the seat, during the tilting of his chest backwards, following a modification of the angular position of the backrest.

Selon l'invention l'ancrage est monté à mobilité dans une coulisse orientée suivant le sens du déplacement de la partie inférieure du dossier et portée par le soubassement du siège. According to the invention, the anchor is mounted for mobility in a slide oriented in the direction of movement of the lower part of the backrest and carried by the base of the seat.

L'ancrage ainsi réalisé évite une compression exagérée de l'abdomen par
la ceinture de sécurité à la suite d'une inclinaison du dossier du siège.The anchoring thus produced avoids excessive compression of the abdomen by
the seat belt following an inclination of the seat back.

D'autres caractéristiques et avantages de l'invention apparaîtront à la
lecture de la description d'exemples de réalisation du dispositif d'ancrage
en référence au dessin annexé dans lequel:
- les figures 1 et 2 sont des vues en élévation d'un siège de véhicule
automobile équipé d'une ceinture de sécurité suivant deux modes de
réalisation du dispositif d'ancrage,
