Abstract: A table unit for a motor-vehicle seat comprises a base plate connected in an articulated manner to a backrest frame of the seat, in such a way as to be movable between an inoperative position, adjacent to a front surface of the seat backrest and an operative position, projecting horizontally in a cantilevered manner from the front surface of the backrest. A table is pivotally mounted on the base plate and is configured to rotate with respect to the base plate selectively about any one of two articulation axes parallel to, and spaced apart form, each other.

Abstract: A device for adjusting the position of a movable part of a vehicle seat. One of two connection elements is secured to the movable part and to the other connection element for rotation about a first axis. A lever mechanism selectively either allows the one connection element to rotate or locks it in a selected angular position. The lever mechanism includes circular toothing around an aperture in the one connection element, at least two gears engaging said toothing and movable with planetary motion about the first axis, and levers arranged to shift the gears between a first position in which they are engaged with each other and with the toothing to prevent rotation of the one connection element and a second position in which the gears are engaged only with the toothing to enable rotation of the one connection element.
