Triple output transfer case for a vehicle seat

A transfer case assembly for selectively moving a seat assembly in a plurality of adjustment directions, said assembly comprising:

• a motor;
• a drive shaft operatively connected to said motor for rotation in response to actuation of said motor;
• a plurality of driving gears mounted to said drive shaft for rotation therewith;
• a plurality of driven shafts corresponding with said respective plurality of driving gears for independently controlling movement of the seat assembly;
• a driven gear rotatably mounted to each of said driven shafts and meshed with a respective one of said driving gears for rotation therewith;
• a coupler disposed adjacent each of said driven gears for selectively coupling said driven gears to said respective driven shafts, said coupler including an engagement ring mounted about said driven shaft, said engagement ring moveable longitudinally along said driven shaft while remaining rotationally fixed relative to said driven shaft;
• and
• a power actuator disposed adjacent each of said coupler for operative engagement therewith for selectively coupling said driven gears with said respective driven shafts and transfer rotation of said drive shaft to rotation of said driven shafts through independent or simultaneous actuation of said actuators and said motor whereby the seat assembly may be moved in one or more of the plurality of adjustment directions.
