1. A vehicle seat adjuster slide assembly comprising:
- an elongated formed guide rail;
an elongated formed slide rail slidably coupled to the elongated formed guide rail with a plurality of plastic bushings disposed between the elongated formed guide rail and the elongated formed slide rail and contacting the elongated formed guide rail, each plastic bushing having a cross sectional area and a plurality of projecting longitudinal runners with a solid cross sectional area, wherein each longitudinal runner'"'"'s cross sectional area is relatively small in relation to that of the plastic bushing wherein the elongated formed slide rail is slidably and stably restrained by the plastic bushings from moving vertically or laterally in relation to the elongated formed guide rail; and
at least one roller carried between and circumferentially engaging the elongated formed guide rail and the elongated formed slide rail to facilitate relative sliding motion therebetween.

Abstract
A vehicle seat adjuster slide assembly. The assembly includes a formed stationary rail for attachment to the vehicle'"'"'s floor structure and for carrying the remaining components of the assembly. A formed sliding rail mates with the stationary rail and adjustably retains a seat within the vehicle. The two rails are stably and slidably engaged through their respective cross sectional features, rollers and sliding bushings.

6. A vehicle seat adjuster slide assembly comprising:
-
a guide rail formed from sheet metal for connection to a vehicle the guide rail including; a substantially vertical base wall; a formed U-shaped top channel extending substantially along the length of the base wall top creating a receptive cavity opening downwardly adjacent to the base wall; a pair of formed U-shaped bottom channels parallel and substantially adjacent to one another extending substantially along the length of the base wall bottom creating two receptive cavities opening upwardly, the first formed U-shaped bottom channel situated adjacent to the base wall diametric to the formed U-shaped top channel the second formed U-shaped bottom channel situated on the same side of the base wall further from the base wall than the first formed U-shaped bottom channel; a slide rail formed from sheet metal for connection to a vehicle seat the slide rail including; a substantially vertical face wall; a pair of side walls perpendicular to the face wall longitudinally disposed substantially along the length of the face wall the first side wall along the top of the face wall the second side wall along the bottom of the face wall both projecting toward the guide rail base wall; a terminal flange extending substantially along each side wall existing in a parallel planar relationship with the face wall the first terminal flange extending upward from the first side wall located in a spaced paired relationship to the receptive cavity of the formed U-shaped top channel of the guide rail, the second terminal flange extending downward from the second side wall located in a spaced paired relationship to the receptive cavity of the first formed U-shaped bottom channel of the guide rail; two upper and two lower plastic bushings including a plurality of longitudinal runners projecting along each bushing, slidably containing the terminal flanges of the slide rail within the opposing top and first bottom formed U-shaped channels of the guide rail; a plurality of cylindrical rollers rotatably contained within the second bottom channel circumferentially engaging the second side wall of the slide rail for aiding sliding movement; and spacing means separating the cylindrical rollers.
