Abstract:
A vehicle seat comprising:first and second seat components pivotally mounted relative to each other about a rotational axis,at least one first pivoting mechanism which comprises a locking device movable between a locked position preventing the relative pivoting between the first and second seat components and an unlocked position allowing a free pivoting between the first and second seat components, this locking device being controlled by a first operating part pivoting about said rotational axis and able to be activated by a user, this first operating part being assisted to a neutral angular position where said first operating part places the locking device into its locked position, and the first operating part being movable in an activating angular direction to an angular activating position where said first operating part places the locking device into its unlocked position, the neutral and activating positions of the first operating part being fixed relative to the first seat component,and an memorization mechanism which is movable between a neutral position where said memorization mechanism is adapted to not interfere with the relative pivoting of the first and second seat components, and an active position where said memorization mechanism is adapted to:allow a free pivoting of the first seat component relative to the second seat component, only in a first angular direction from the last relative adjusted position of these two seat components,then to allow a free pivoting of the first seat component relative to the second seat component, in a second angular direction opposite to the first angular direction, only as far as said last relative adjusted position of these two seat components,the memorization mechanism being controlled by a second operating part pivotally mounted and able to be activated by a user, this second operating part being assisted to a neutral angular position where said second operating part places the memorization mechanism into its neutral position, and the second operating part being movable in said activating angular direction to an activating angular position where said second operating part places the memorization mechanism in its active position,wherein the memorization mechanism is distinct from the first pivoting mechanism,wherein the first and second operating parts are connected together by a lost motion mechanical connection which is adapted:to leave fixed the second operating part when the first operating part is acted upon to move it into its activating position,and to drive the first operating part from its neutral position to its activating position when the second operating part is acted upon to move it from its neutral position to its activating position,and wherein the angular neutral and activating positions of the second operating part are fixed relative to the first seat component.
