The present invention relates to an electric seat track apparatus for a dual motor type vehicle, comprising: multiple lower rails fixed to the bottom inside a vehicle, and where a lead screw is fixed and installed along a longitudinal direction; multiple upper rails sliding along the lower rail; a seat mounted on the multiple upper rails; motors respectively combined with the multiple upper rails; and multiple gear boxes fixed to the upper rails, and having a gear part respectively connected with the multiple motors to move the upper rail in the longitudinal direction of the lead screw by the output of the motor. A conventional electric seat track apparatus for a vehicle comprises a supporting frame for connecting two upper rails, one motor, and a driving shaft for transmitting a rotational force of the motor to the gear boxes respectively equipped in the upper rails, so vibrations and noises were generated. However, the present invention has an effect of reducing noises by removing a supporting frame and by respectively mounting a motor having a level of performance that is half of that of a conventional motor, and a gear box on two upper rails. |
