Abstract

L'invention concerne une seringue (50) pouvant se déplacer sous l'effet de la force de ressorts (7, 9, 11) dans un boîtier (14, 16). Des moyens de transmission (4, 5) transmettent la force des ressorts à la seringue (50), et des cames d'arrêt (31) faisant ressort, qui viennent s'engager dans une rainure (32) des moyens de transmission (4, 5), maintiennent ces derniers (4, 5) dans leur position jusqu'au déclenchement de l'injection. Pour la préparation de l'injection, une tête de déclenchement (13) coulissant axialement est déplacée vers l'arrière pour passer de la position représentée à une position dans laquelle le système de sécurité de l'auto-injecteur est retiré. Pour le déclenchement d'une injection, la tête de déclenchement (13) est déplacée vers l'avant. Des languettes faisant ressort, situées sur la tête de déclenchement (13), viennent alors en contact avec les cames d'arrêt (31) pour les écarter. Des boutons de repositionnement (62) placés dans la tête de déclenchement agissent, une fois actionnés, sur les languettes de sorte qu'elles ne viennent pas en contact avec les cames d'arrêt (31) lorsque la tête de déclenchement est déplacée vers l'avant.
