ABSTRACT:
A resilient seat back return device used in two-door vehicles is provided. Between the mobile flange of the articulation and the fixed flange of the same articulation a connection link is pivotally mounted to the sitting portion flange whereby, the connection link is connected by a small helical spring to the module flange of the seat back so that, when the seat back is lowered over the sitting portion, the spring is in an unstressed state while the spring is normally under tension when the seat back occupies an intermediate position and is sufficiently stressed when the seat back is placed in the prolongation of the sitting portion to form a berth, the spring then occupying a position in which it is sufficiently powerful to move up the seat back from the seat. Due to its fixation points a spring of small volume and of short elongation but with a very high pulling force is used.
