ABSTRACT:
The covering (20) for a seat, made from an outer envelope (21) and an inner padding (22) shaped into a central pad (221) bordered by two side wings (222), where the pad (221) and wings (222) are arranged so as to form a pan (200), the concavity of which is intended to receive an occupant, where the padding (22) takes the form of a unit (30) consisting of comprising two elements (31, 32) separated by a joining surface (300), and where that one (31) of these elements (31, 32) which is closes to the pan (200) is made from a material which has a softer consistency than that of the material of the other one (32) of these elements (31, 32), so that when the pan (200) of the padding receives an occupant, the force exerted on the covering (20) straight the pad (221) causes the wings (222) automatically to be brought closer to each other by pivoting about a hinge zone (3020), and vice versa.
