ABSTRACT:
A clutch for a vehicle seat adjuster or the like includes a central shaft that extends coaxially through a sleeve type solenoid plunger, with a drive gear nested within a cup shaped pawl on the end of the shaft. A short rod is slidably contained in the shaft normal to the shaft axis, and surrounded by a pair of steel balls held in a cylindrical wall of the drive gear, which are in turn surrounded by the stepped inner diameter of a cylindrical wall of the pawl. When the solenoid shifts the pawl back and forth, the balls are shifted toward or away from the rod, so as to make or break a positive driving connection therewith.
