Abstract
A back-rest adjuster with a free pivot device for a vehicle seat comprises between a drive device and the gearing which adjusts the fitting parts (5, 6) in relation to each other a shiftable clutch which has to be released for free pivoting and which comprises two clutch parts (13, 14) adpated for movement in an axial direction and in relation to each other. Associated with one clutch part and adapted for movement together with and disposed concentrically in relation to it is a memory ring (15) disposed between a drive ring (19) which is non-rotatable in relation to one fitting part (6) and a ratchet ring (21) which is non-rotatable in relation to the other fitting part (5). The memory ring (15) and the drive ring (19) which, when the clutch is released, are capable of limited rotation in relation to each other, are form-lockingly coupled to each other only in one single position at the end of the range of rotation, when the clutch is closed. When the clutch is released, the memory ring (15) is in any rotary position capable of being form-lockingly coupled to the ratchet ring (21) which is non-rotatable in relation to the other fitting part (5).
