    qu'il est prévu une came (130) en forme de D, qui comporte, sur sa périphérie extérieure, une surface de came, qui peut être amenée en contact avec le pied (90) du dispositif de support, de manière à déplacer ce dernier au moins partiellement entre la position ouverte et chacune des positions fermées, et
    que la surface de came comprend une partie en forme d'arc de cercle (134) et une partie plane (136), la partie en forme d'arc de cercle (134) de la surface de came étant en contact avec le pied (90) lors du déplacement de ce dernier entre les différentes positions fermées, et que la partie plane (136) de la surface de came est en contact avec le pied (90) pendant au moins une partie du déplacement du pied (90) entre la position ouverte et chacune des positions fermées.
  3. Dispositif selon la revendication 1,
    caractérisé en ce
    que le mécanisme comprend une première roue dentée qui est reliée de telle sorte qu'elle se déplace avec le galet de came, et une seconde roue dentée, qui engrène avec la première roue dentée, le pignon (120) étant agencé de telle sorte qu'il se déplace avec la seconde roue dentée.
  4. Dispositif selon la revendication 1,
    caractérisé en ce
    que la crémaillère (80) est montée de telle sorte que cette dernière se déplace en glissant sur la poche (10), le dispositif de support (70,72,74) étant relié à la crémaillère (80) de telle sorte que le dispositif se déplace en glissant avec la crémaillère (80).
  5. Dispositif selon la revendication 4,
    caractérisé en ce
    qu'il est prévu un dispositif, à l'aide duquel le dispositif de support (70,72,74) est monté sur la crémaillère (80), de sorte que le dispositif de support (70,72,74) peut exécuter un mouvement de rotation par rapport à la crémaillère (80).
  6. Dispositif selon la revendication 1,
    caractérisé en ce
    que le mécanisme comprend une roue dentée d'actionnement, sur laquelle est monté le galet de came;
    qu'une roue dentée d'entraínement engrène avec la roue dentée d'actionnement; et
    qu'il est prévu un dispositif à l'aide duquel le dispositif de support se déplace entre la position ouverte et chacune des positions fermées en réaction à la rotation de la roue dentée d'entraínement.
  7. Dispositif selon la revendication 1,
    caractérisé en ce
    que le dispositif de support (70,72,74) comprend un composant, qui est tourillonné sur la crémaillère (80) et exécute, par rapport à la crémaillère (80), un mouvement de rotation entre la position ouverte et les positions fermées.
  8. Dispositif selon la revendication 7,
    caractérisé en ce
    que la crémaillère (80) est montée sur la poche (10) de telle sorte que cette dernière peut se déplacer en glissant; et qu'en réaction au mouvement de glissement de la crémaillère (80), le composant est déplacé entre les différentes positions fermées.
  9. Dispositif selon la revendication 1,
    caractérisé par
    un dispositif, qui est relié au pignon (120) et au galet de came et qui fait tourner le pignon (120) en réaction au déplacement du galet de came, la crémaillère (80) étant déplaçable en réaction au pignon (120) de manière à déplacer le dispositif de support entre les positions fermées et la position ouverte; et
    une came, avec laquelle le galet de came vient en contact, ce qui provoque un déplacement du galet de came et une rotation du pignon (120).
  10. Dispositif selon la revendication 9,
    caractérisé en ce
    que le dispositif, qui est relié au pignon (120) et au galet de came pour faire tourner le pignon (120) en réaction au déplacement du galet de came, comprend ce qui suit :
    un arbre (110), qui peut tourner autour d'un premier axe, le pignon (120) pouvant tourner avec l'arbre (110) autour du premier axe;
    une roue dentée d'entraínement, qui peut tourner avec l'arbre (110) autour du premier axe; et
    une roue dentée d'actionnement qui est déplaçable avec le galet de came autour d'un second axe distant du premier axe, la roue dentée d'actionnement engrenant avec la roue dentée d'entraínement.
  11. Dispositif selon la revendication 2,
    caractérisé en ce
       que la partie plane (136) de la surface de came est en contact avec le dispositif de support (70,72,74) pendant le déplacement partiel du dispositif de support (70,72,74) depuis la position ouverte jusque dans chacune des positions fermées.
