Abstract:
(EN) The disclosure in the present specification relates to provision of a seat cushion extension device which can slide a seat cushion through a single spring, which has a simple structure, and which has a high assembly efficiency and a low weight. According to an embodiment of the disclosure in the present specification, a seat cushion extension device comprises: a base comprising first and second rack gears formed to face each other; a cushion portion formed on the upper portion of the base to be able to move forward/backward; a locking gear portion which is coupled to a shaft extending from the cushion portion to the base, and which comprises a first gear formed to engage with the first and second rack gears; and a manipulation portion which is coupled to the cushion portion to be able to move forward/backward between the cushion portion and the first gear, and which has a protruding portion formed on the bottom surface thereof, wherein, when the manipulation portion is moved backward such that the protruding portion lowers the first gear, the first gear is disconnected from the second rack gear, and the cushion portion is switched such that the same can slide.
(FR) La présente invention concerne un dispositif d'extension de coussin de siège permettant de faire coulisser un coussin de siège par l'intermédiaire d'un seul ressort, présentant une structure simple, et qui a un rendement d'assemblage élevé et un poids faible. Selon un mode de réalisation de la présente invention, un dispositif d'extension de coussin de siège comprend : une base comprenant des premier et second engrenages à crémaillère conçus de sorte à se faire face ; une partie coussin formée sur la partie supérieure de la base pour pouvoir se déplacer vers l'avant/vers l'arrière ; une partie engrenage de verrouillage qui est accouplée à un arbre s'étendant à partir de la partie coussin vers la base, et qui comprend un premier engrenage conçu pour venir en prise avec les premier et second engrenages à crémaillère ; et une partie de manipulation qui est accouplée à la partie coussin de sorte à pouvoir se déplacer vers l'avant/vers l'arrière entre la partie coussin et le premier engrenage, et qui comporte une partie saillante formée sur sa surface inférieure, le premier engrenage étant séparé du second engrenage à crémaillère lorsque la partie de manipulation est déplacée vers l'arrière de sorte que la partie en saillie abaisse le premier engrenage, et la partie coussin est commutée de sorte à pouvoir coulisser.
