Abstract
A seat has: a moveable upper part (14) for receiving at least one occupant, the moveable upper part being carried by a fixed lower part forming a substructure (16), and a turning mechanism (28) for turning the upper part (14) backwards and forwards. The turning mechanism (28) contains a pivot (30) connecting the upper part (14) and the substructure (16). The axis (Z) of this pivot is substantially vertical. The turning mechanism (28) also contains a slide (36) mounted on the upper part (14) so as to be displaceable in rotation about the pivot (30) and in translational motion substantially perpendicular to the axis (Z), and two complementary cams (46, 48) carried respectively by the substructure (16) and the upper part (14). One of the cams has a developing profile imparting a predetermined turning travel to the upper part (14).
