Abstract: A runner for a vehicle seat, comprising a male bar and a female bar that are mounted to move relative to each other over a predetermined stroke, the runner further comprising a detector disposed on one of the male and female bars, and a detectable member disposed on the other of the male and female bars. The male bar is a generally channel section bar including a horizontal web, the female bar is a generally channel section bar including a horizontal web, and the detectable member is formed by a tab that is integral with or secured to the edge of one of the lips of the male bar, the corresponding side wall of the second bar having an opening disposed in correspondence with the detector adapted to detect the presence or the absence of the tab of the male bar.

Abstract: A vehicle seat comprising a seat proper, a back presenting at least a folding portion, a rigid plate between the seat proper and the folding portion, a control mechanism for locking the folding portion, and a control member. The control mechanism has a control piece that is pivotally mounted about an axis, said control piece being urged about the axis towards a rest position, the piece having a guide slot in which there slides a peg that is secured to the rigid plate, a first lateral branch extends to a closed end for receiving the peg when the folding portion is raised, and a second lateral branch extending to a closed end receives the peg when the folding portion is folded down.

Abstract: The present invention relates to a runner for a vehicle seat, the runner comprising a male bar and a female bar that are mounted to move relative to each other over a predetermined stroke (L), the runner further comprising a detector (18) disposed on one of the male and female bars, and a detectable member (94) disposed on the other of the male and female bars. The male bar (9) is a generally channel section bar including a horizontal web (91), the female bar (8) is a generally channel section bar including a horizontal web (81), and the detectable member is formed by a tab (94) that is integral with or secured to the edge (93b) of one of the lips (93) of the male bar, the corresponding side wall (8a) of the second bar (8) having an opening (86) disposed in correspondence with the detector (18) adapted to detect the presence or the absence of the tab (94) of the male bar (9).
