  • Our mechanism allows the user of the seats in which the first one is integrated, to have the possibility of reclining the backrest and simultaneously projecting the seat towards the front, thus, when a user sits looking for the most comfortable position, and makes a slight movement impulse backward with the upper back, which drives the backrest, simultaneously moving the seat to the front.
  • the backrest and the seat are integrated by two square tube frames folded in shape of "U" (elements 1 and 2), joined at their terminals union-, which have an ironed punch and a punch through which a screw passes (element 10), with a nylon washer that functions as a separator (element 8), which integrates a lock nut (element 12) . With this joint a hinge movement is formed.

  • This stabilizer bar of the seat has terminal ends reduced in its diameter, which are first introduced to a spacer (element 9) whose function is to center the bar and prevent lateral movements and then to a bushing (element 5), the which crosses and is welded to the sides of the seat structure (element 13), said bushing has the following characteristics:
  • the middle part consists of a vulcanized natural rubber layer and the inner layer is in nylon sectioned to the center of its length, through which the ends of the seat stabilizer bar (element 4) pass.
  • the user has a very comfortable, spacious, quiet seat that allows him to have a wide range of recline postures, for the benefit of an adequate isoptic.

Abstract

L'invention concerne un mécanisme qui, entre autres avantages, permet d'effectuer une inclinaison ponctuelle et précise de l'appui et, simultanément, de faire coulisser le siège, optimisant ainsi une isoptique appropriée dans des salles de cinéma et de théâtre. Ce mécanisme, caractérisé par un fonctionnement silencieux, satisfait une exigence croissante de confort et d'espace. Ce modèle, qui permet d'éviter totalement les bruits, tout en permettant une inclinaison réglée selon le plaisir de l'utilisateur, au bénéfice d'une isoptique appropriée, est composé d'une paire de coussinets qui comportent une enveloppe rectangulaire et qui présentent une rainure dentée. Cette rainure dentée comprime une barre stabilisatrice soudée à la partie inférieure du siège et permet le coulissement de cette barre stabilisatrice dans son intérieur. Le siège est uni par une articulation à l'appui, lequel comporte une barre soudée dans sa partie inférieure, qui s'insère dans une paire de moyeux au niveau de ses extrémités, ce qui génère un mouvement pendulaire, en les intégrant en un seul mouvement contrôlé, ponctuel et précis.
