ABSTRACT:
A seat bottom fame assembly providing a support surface for a vehicular seat includes first and second track assemblies. The first track assembly is fixedly secured to a floor of a passenger compartment. The second track assembly is slidingly connected to the first track assembly. A manually actuated seat adjuster is attached to the first and second track assemblies to permit selective sliding of the second track assembly with respect to the first track assembly. The manually actuated seat adjuster includes a rotatable driveshaft having first and second ends. A drive nut is threadingly engaged with the driveshaft between the first and second ends. A first element is fixedly secured to the first end of the driveshaft. A second element is rotatably mounted on the first end of the driveshaft and selectively engaged with the first element. An actuation member is operatively connected to the second element to selectively disengage the second element from the first element to permit rotation of the driveshaft within the drive nut. The actuation member also selectively engages the second element with the first element to prevent rotation of the driveshaft within the drive nut.
