Abstract: A mechanical seat recline lock mechanism that employs a lead screw device to backdrive a nut and disk. The disk is held in place by a spring-loaded friction pin when motion needs to be constrained. The rotating disk can be oiled or greased to provide damping action.

Abstract: An electric motor and method for reducing or eliminating end play. The motor comprises an adjustment member that cooperates with an end lamina member to facilitate reducing end play. The adjustment member is slidably mounted on an armature shaft and inside an aperture of a portion of the end lamina tube to reduce or eliminate end play. Thereafter, the adjustment member is permanently secured to the end lamina tube. In another illustrative embodiment, the movable bearing retainer sets endplay and also retains brushes in an open position prior to, for example, assembly of the motor.
