ABSTRACT:
A seat with a reversible back rest having on each side of the cushion (14), two coupling rods (20, 22) articulated on the lower part of the back rest (18) and on a vertical support plate (16) at two points (24, 26) situated on a same horizontal line, with the result that the back rest may pivot between two service positions symmetrical relative to the mid point (x-y) of the segment formed by said two points. It furthermore comprises a back rest-locking connecting rod (32) mounted on each side of the seat, a first end (34) of each connecting rod being articulated on the lower part of the back rest and a second end (36) being accommodated in a vertical slot (38) formed on the support plate (16) in said mid point (x-y) where it may slide, retractable stop means (40) intended to keep said second end of the connecting rod in said position, and control means (46, 62) which may be actuated by the operator and are intended to retract the stop means so as to enable said second end of the connecting rod to slide freely in the slot (38).
