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.
