Seat track assembly and method of manufacture

摘要

A seat track assembly for an automotive seat positioner mechanism includes a threaded spindle fixed at one end to a lower track and a mating nut in a gear case on the spindle mounted to an upper track by a bracket attached thereto. The bracket is stabilized against crash forces by interfit portions on the bracket and side walls of the upper track. The spindle is directly attached to the lower track by fasteners passed through a flattened end of the spindle and a bottom wall of the lower track.
