Position adjuster for the angular or vertical adjustment of a motor vehicle seat or for lifting a window, includes two mount levers connected respectively to a pair of wobble gears controlled by an eccentric; the eccentric is formed of a carrier disk rigidly connected to a rotary shaft and defining a concentric circumferential portion limited by two radially directed abutment surfaces and forming with the center of the shaft an angle of more than 180.degree.; the eccentric part is formed of two circumferentially movable wedge-like segments urged one from the other by a pressure spring so that during the rest position of the adjuster the segments are in their locking position, in which radial play in bearings and backlash in the teeth of wobble gears is eliminated; during the rotation of the shaft, one of the segments is displaced against the biasing spring and radial play facilitating the manipulation is introduced between the wobble gears.
A position adjuster for seats and/or windows, particularly in motor vehicles, comprising two mount levers, a rotary shaft for interconnecting said levers, an inner gear connected to one lever and a spur gear ring connected to the other lever and being in mesh with said inner gear, the crown circle of said spur gear ring being smaller at least about one tooth than the root circle of said inner gear, an eccentric arranged for joint rotation with said shaft and supporting one of said gears to impart a wobbling movement thereto, said eccentric including a carrier disk connected to said rotary shaft, a pair of wedge-like segments supported one after the other for movement on a major portion of the circumference of said carrier disk, and a resilient pressure means arranged between said segments to urge the same one from the other into a locking position in which radial play between the assigned gear and said carrier disk is eliminated, whereby during the rotation of said shaft said segments are displaced towards each other against said pressure means to permit a radial play between said gear and said carrier disk.
A position adjuster for seats and/or windows, particularly in a motor vehicle, comprising hinge mount levers interconnected by a rotary shaft, an inner gear formed on one of said levers and a spur gear ring formed on the other lever and having the crown circle of its teeth less at least about the height of one tooth than the root circle of the inner gear, an eccentric arranged for joint rotation with said shaft and supporting one of said gears, said eccentric including a recessed portion in said shaft defining two radially directed abutment surfaces and two wedge-like segments having inwardly directed noses projecting into said recessed portion, and resilient pressure means arranged between the juxtaposed end surfaces of said noses.
