ABSTRACT:
The mechanism uses a drive block having mounting lugs on both transverse sides of the block for mounting in slots on opposed sides of a C-shaped bracket. The slots in the bracket are T-shaped, the body of the T accepting the mounting lugs for passage to the circular T head opening. By rotating the block 90.degree., the lugs rest in the circular opening and are held in place. Each lug has a necked down section passing through the slotted opening of the brackets. Each lug has an enlarged head extending outwardly of the bracket sides to prevent the bracket sides from spreading in response to shock forces acting on the seat track. The block has a central threaded opening to accept a lead screw for driving the seat track responsive to rotation of the lead screw. The bracket is secured to the seat track and the drive block is inserted into the bracket, rotated to position and mated with the lead screw.
