Abstract

Un ensemble de siège comprend un coussin de siège et un dossier de siège pouvant accomplir un mouvement de pivotement entre une position d'assise droite et une position de repli vers l'avant. Un mécanisme d'inclinaison est accouplé entre le coussin de siège et le dossier de siège pour passer d'un état bloqué à un état débloqué et inversement, et permettre ainsi le mouvement de pivotement du dossier de siège. Une glissière de siège est accouplée au coussin de siège pour passer d'un état bloqué à un état débloqué et inversement, et permettre ainsi le mouvement coulissant vers l'avant et vers l'arrière de l'ensemble de siège. Un mécanisme à relâchement pour entrée facile doté d'un bouton-poussoir est accouplé au mécanisme d'inclinaison et à la glissière de siège afin de faire passer le mécanisme d'inclinaison et la glissière de siège en état débloqué et permettre le mouvement de l'ensemble de siège pour qu'il adopte une position d'entrée facile dans laquelle le dossier de siège a pivoté dans la position de repli vers l'avant et la glissière de siège a fait glisser complètement l'ensemble de siège vers l'avant, ce qui donne accès à l'espace situé derrière l'ensemble de siège.
