Abstract
A vehicle seat comprises a backrest mounted on a seat by means of a pivot mechanism comprising two flanges fixed respectively to the seat and the backrest and linked one to the other by means of a single-train hypocycloid gear mechanism which causes the backrest to pivot about an axis of rotation which in turn moves in circular translation about a fixed axis. The gear mechanism is driven by a control shaft which is centered on the axis of rotation on a level with said gear mechanism and which has a part forming a crank comprising an end centered on the fixed axis, which end is driven in rotation by an electric motor mounted on the seat part.
