Abstract

A foldable rear seat for a motor vehicle is disclosed. A connecting bar which is pivoted to the seat portion and to the back portion has a first pivot axis below the plane P containing both the pivot axis connecting a connecting link member of the seat portion to the floor and the pivot axis connecting the connecting bar to the back portion. A guide ramp provides for guiding translatory movement of a point A of the connecting bar, for the purpose of raising the first axis above said plane.

Claims

1. A convertible seat for a motor vehicle, movable between a normal position and a folded position, and comprising:

a seat portion pivotable about a first transverse axis;

a back portion pivotable about a second transverse axis;

a link member having one end pivoting about a third transverse axis fixed to said vehicle and another end pivoting about said first transverse axis;

a connecting bar pivoted to said seat portion at a fourth transverse axis and to said back portion at a fifth transverse axis, so as to ensure simultaneous movement of said seat and back portions; and

a guide means fixed to said vehicle and contacting a portion of said connecting bar for guiding said portion of said connecting bar during movement of said seat portions;

wherein said axes are positioned such that fourth axis is below a plane containing said third and fifth axes when said seat is in said normal position, and wherein said guide means is contoured to guide said fourth axis above said plane when said seat is moved to said folded position.

2. The seat of claim 1 wherein said guide means is a guide ramp and said portion of said connecting bar is a roller movable along said ramp.

3. The seat of claim 2 wherein said ramp descends toward said second axis and includes a portion forming a housing which holds said roller when said seat is in said normal position.

4. The seat of claim 1 or 2 or 3 wherein said portion of said connecting bar is on said fourth axis.
