VEHICLE SEAT TRACK ASSEMBLY HAVING A SINGLE TOOTHED BELT DRIVE MECHANISM
First Claim
1. A vehicle seat track assembly comprising:
- a first track portion including a first track, a second track, a bracket connected to the first track and including first and second portions, a toothed drive nut including a threaded bore, and a lead screw passing through the first portion of the bracket, the toothed drive nut and the second portion of the bracket;
a second track portion arranged parallel to the first track portion and including a first track, a second track, a bracket connected to the first track and including first and second portions, a toothed drive nut including a threaded bore, and a lead screw passing through the first portion of the bracket, the toothed drive nut and the second portion of the bracket; and
a third track portion comprising a motor having an output shaft, an output speed reducing mechanism coupled to the output shaft, a toothed drive pulley coupled to the output speed reducing mechanism, and a continuous toothed belt that is rotated by the toothed drive pulley and that causes rotation of the toothed drive nut of the first track portion and the toothed drive nut of the second track portion.

Abstract
A drive mechanism for a vehicle seat track assembly includes a housing and a motor having an output shaft. An output speed reducing mechanism is coupled to the output shaft. The motor and the output speed reducing mechanism are mounted to the housing. A toothed drive pulley is rotatably mounted to the housing and coupled to the output speed reducing mechanism. A first toothed pulley is rotatably mounted at a first end of the housing. A second toothed pulley is rotatably mounted at a second end of the housing. A continuous toothed belt is rotated by the toothed drive pulley and causes rotation of the first and second toothed pulleys.
