摘要： A seat adjustment mechanism especially suited for motor vehicle seats is composed of at least one motor mechanism for adjustably moving a seat member through a drive connection having at least two mutually engaging force transmission parts. In order to avoid rattling of the adjustment mechanism when adjusting movement of the seat is to be effected in a direction where the adjusting movement is abetted by the weight of the seat member itself, a braking device is provided which counteracts the adjusting force of the motor mechanism applied in that direction.
