The torsion spring 154 biases the distal end of the leg 122' upwards.

  • the windows 78' disengage from the latching teeth 80' of the fixed track 20', thereby unlocking the movable track 22' relative to the fixed track 20' to allow forward and rearward sliding movement of the movable track 22'. Because the latch body 74' and the rearward end 90' of the memory bar 87' move downward together, the second tab 86' remains in the recess 114'.
  • the latch body 74' re-positions the memory bar 87' every time the seat assembly 12' is adjusted to one of the plurality of seating positions using the towel bar 120'.
  • the leaf spring 82' biases the latch body 74' upwards such that the windows 78' re-engage the latching teeth 80' of the fixed track 20', thereby locking the movable track 22' relative to the fixed track 20'.
  • the second tab 86' enters the elongated portion 113' of the slot 109' and the latch mechanism 72' remains unlocked until the second tab 86' once again reaches the recess 114' at the second end 112'.
  • the second tab 86' engages the upper edge 146' of the slot 109', which prevents the latch body 74' from moving upwardly such that the windows 78' do not re-engage the latching teeth 80' of the fixed track 20'.
  • the second tab 86' travels forward along the elongated portion 113' of the slot 109' until the movable track 22' reaches its foremost position, defining the easy entry position of the seat assembly 12'.
  • the leaf spring 82' biases the latch body 74' upwards such that the windows 78' reengage the latching teeth 80' of the fixed track 20', thereby locking the movable track 22' relative to the fixed track 20'. It is thus recognized that because the memory bar 87' remains stationary during the movement of the seat assembly 12' to the easy entry position, the seat assembly 12' is returned to the previously selected seating position.

Abstract

L'invention concerne un ensemble rail de siège comprenant un rail fixe et un rail mobile accouplé de manière coulissante au rail fixe. Un verrou est mis en action entre une position verrouillée verrouillant le rail fixe et le rail mobile et une position déverrouillée permettant un mouvement coulissant du rail mobile. Une barre de mémoire est mise en prise avec le rail fixe pour définir une position initiale du rail mobile. Un levier actionne le verrou pour le mettre sur la position déverrouillée pour permettre un mouvement coulissant du rail mobile entre la position initiale et une position d'accès facile. Une barre horizontale désaccouple de manière sélective la barre de mémoire par rapport au rail fixe et la barre de mémoire actionne le verrou pour le mettre sur la position déverrouillée de sorte que le mouvement coulissant du rail mobile repositionne la barre de mémoire sur une nouvelle position initiale.
