ABSTRACT:
An automotive powered seat slide device including upper and lower guide rails, slidably fitted to each other, such that the position of the seat relative to the floor is adjusted frontwardly and rearwardly, includes a driving mechanism having a driven connection with an electric motor and a screw-threaded shaft rotatably mounted on the upper rail in an aperture defined in the slidably fitted pair of rails and a nut member engaged with the screw-threaded shaft and rigidly mounted on the lower rail for rotation relative to the screw-threaded shaft. One end of the screw-threaded shaft is rotatably supported by the upper rail, the other end of the screw-threaded shaft is constructed as a free end so as to permit a proper flexibility of the screw-threaded shaft. An elastomeric mass is also attached to the free end of the screw-threaded shaft, so as to prevent a direct contact between the free end and the inner wall of at least one of the upper and lower rails and to achieve an exact dynamic balance of the screw-threaded shaft.
