Abstract

L'invention concerne un dispositif d'actionnement pour le réglage de la hauteur du siège un fauteuil de dentiste Elle est caractérisée en ce que le dispositif comporte une tige filetée dont une extrémité est articulée sur ladite base du siège, un écrou coopérant avec ladite tige filetée et entraîné par un moteur à engrenage pourvu de broches perpendiculaires au plan de pivotement d'un mécanisme à parallélogramme, lesdites broches s'engageant dans des logements menagés dans un support solidaire d'un bras dudit mécanisme à parallélogramme, de façon telle que lors du fonctionnement du moteur précité l'écrou soit entraîné en rotation et que ladite tige filetée se déplace axialement par rapport audit écrou afin de faire monter ou descendre ledit siège du fauteuil, ledit logement des broches précitées étant agencé de manière à permettre auxdites broches de se déplacer dans la direction de ladite tige filetée afin de provoquer l'arrêt dudit moteur lorsque le mouvement descendant dudit siège du fauteuil est empêché par un obstacle Elle se rapporte aux sièges réglables en hauteur.The invention relates to an actuating device for adjusting the height of the seat of a dentist's chair.It is characterized in that the device comprises a threaded rod, one end of which is articulated on said base of the seat, a nut cooperating with said rod threaded and driven by a gear motor provided with pins perpendicular to the pivot plane of a parallelogram mechanism, said pins engaging in housings formed in a support integral with an arm of said parallelogram mechanism, such that when operation of the aforementioned motor the nut is driven in rotation and that said threaded rod moves axially with respect to said nut in order to raise or lower said seat of the chair, said housing of the aforementioned pins being arranged so as to allow said pins to be moving in the direction of said threaded rod to cause said motor to stop when the downward movement of said seat d The wheelchair is blocked by an obstacle It relates to height-adjustable seats.
