Single motor power seat

A single motor gearbox assembly (100) for driving multiple selected outputs, the assembly comprising:

• a housing (102);
• a shift motor (104) supported by the housing (102);
• a drive motor (116) supported by the housing (102) for driving a main drive gear (140);
• a plurality of spaced apart output gears (112a-112c) rotatably supported by the housing (102) and selectively driven by the drive motor (116);
• a drive selection arm (110) operatively coupled to said shift motor (104) for actuation between select positions aligned with at least one of said output gears (112a-112c), said drive selection arm (110) including an intermediate gear (132) meshed between said main drive gear (140) and one of said output gears (112a-112c) in response to alignment of said drive selection arm (110) with the output gear (112a-112c) in the select position for actuating and driving the output gear (112a-112c) and the selected output;
• and
• a plurality of micro-switches (114a-114c) operably connected to interchangeably activate and deactivate the shift motor (104) for alignment of the drive selection arm (110) with one of the output gears (112a-112c) and the drive motor (116) for driving the main (140), intermediate (132), and output gears (112a-112c).
