Selon l'invention, ce problème est résolu du fait que le levier According to the invention, this problem is solved by the fact that the lever

Du fait de la supression du mécanisme à manivelle entre le levier pivotant et les deux leviers coudés, le poids total du siège est nettement plus faible et on améliore en outre la fiabilité du fonctionnement tout en réduisant la vulnérabilité Due to the crank mechanism being depressed between the pivoting lever and the two crank levers, the total weight of the seat is much lower and the reliability of the operation is improved while reducing the vulnerability

Avantageusement, on dispose, à une extrémité de chaque levier coudé, un tourillon qui traverse une fente de la plaque et Advantageously, at one end of each crank lever, there is a trunnion which passes through a slot of the plate and

Une branche de chaque levier coudé est soumise à l'action d'un ressort de traction dont une extrémité est reliée à la plaque qui lui est associée de manière que lorsque le levier pivotant est libéré, le cliquet denté vienne en prise avec le secteur denté. Selon une première forme de réalisation, les longerons latéraux de la partie formant siège sont reliés au plancher du véhicule A branch of each bent lever is subjected to the action of a tension spring whose one end is connected to the associated plate so that when the pivoting lever is released, the toothed ratchet engages with the toothed sector . According to a first embodiment, the side rails of the seat part are connected to the floor of the vehicle

Since the connecting tube supporting the torsion springs serves simultaneously as a support for the central spar and thus fulfills two functions, it is possible to eliminate a particular support. total weight of the seat is reduced to the extent that it is given to the connecting pipe

Le mode de fonctionnement du siège selon l'invention est le suivant Dans la position dans laquelle le bord arrière de la partie formant siège est abaissée, les divers éléments sont dans la position représentée à la figure 1 L'essentiel dans ce cas est que les deux ressorts de torsion 35, 36 soient, dans cette The operating mode of the seat according to the invention is the following In the position in which the rear edge of the seat portion is lowered, the various elements are in the position shown in Figure 1 The main point in this case is that the two torsion springs 35, 36 are, in this
position, mis sous tension.position, turned on.
Si le siège est utilisé par une personne dont la taille est relativement petite, le bord arrière de la partie formant siège doit être soulevé pour que l'utilisateur du siège puisse voir facilement la route qui est devant lui Pour amener le bord arrière de la partie formant siège en position soulevée, il suffit que l'utilisateur fasse pivoter le levier pivotant 21 dans le sens des aiguilles d'une montre sur la figure 1 Le résultat est que les deux leviers coudés 25, 26 pivotent dans le même sens par l'intermédiaire du coude 22 et que les tourillons 27, 28 se déplacent également dans le -20 sens des aiguilles d'une montre dans les fentes de guidage 29, 30 des deux cliquets dentés 15, 16 Les dents des deux cliquets dentés 15, 16 se dégagent donc des secteurs dentés 13, 14, comme représenté à la figure 4 La force élastique qui a été emmagasinée dans les deux ressorts de torsion 35, 36 est alors libérée et amène les deux éléments en angle 7, 8, la tige de liaison 6 qui en est solidaire ainsi que les plaques 19, 20 montées à rotation sur celle-ci, dans la position représentée aux figures 2 et 3, ou dans une position intermé diaire. Quand on n'exerce plus d'action sur le levier pivotant 21, les ressorts de traction 31, 32 font à nouveau pivoter les leviers coudés 25, 26 dans le sens inverse des aiguilles d'une montre, avec pour conséquence que les deux cliquets dentés 15, 16 sont ramenés par les tourillons 27, 28, en position d'engrènement, position dans laquelle ils viennent en prise avec les secteurs If the seat is used by a person of relatively small size, the rear edge of the seat portion must be lifted so that the seat user can easily see the road in front of him To bring the rear edge of the seat In the raised position, it is sufficient for the user to pivot the pivoting lever 21 in a clockwise direction in FIG. 1. The result is that the two bent levers 25, 26 pivot in the same direction by the intermediate of the elbow 22 and that the pins 27, 28 also move in the direction of clockwise in the guide slots 29, 30 of the two toothed pawls 15, 16 The teeth of the two toothed pawls 15, 16 is thus release toothed sectors 13, 14, as shown in Figure 4 The elastic force which has been stored in the two torsion springs 35, 36 is then released and brings the two elements at an angle 7, 8, the rod of lia ison 6 which is secured thereto and the plates 19, 20 mounted to rotate thereon, in the position shown in Figures 2 and 3, or in an intermediate position. When no action is exerted on the pivoting lever 21, the traction springs 31, 32 cause the bent levers 25, 26 to pivot again in the counterclockwise direction, with the consequence that the two ratchets 15, 16 are returned by the journals 27, 28, in meshing position, in which position they engage with the sectors

La mise en tension des deux ressorts de torsion 35, 36 s'effec- The tensioning of the two torsion springs 35, 36 is effected
tue par pivotement du levier pivotant 21 dans le sens des aiguilles d'une montre et il en résulte une sollicitation de la partie formant siège du siège qui parvient de ce fait dans la position représentée à la figure 2, ou dans une position intermédiaire. the pivoting lever 21 is pivoted in the direction of clockwise and this results in a biasing of the seat portion of the seat which thereby arrives in the position shown in Figure 2, or in an intermediate position.
