Abstract
A method for connecting a headrest guide tube in a vehicle seat frame comprises the steps of forming a hole in the seat frame, inserting a headrest guide tube into the hole, axially compressing the tube to form a pair of rings on opposite sides of the frame wall, and then axially crushing the rings to form a pair of beads tightly clamping the headrest guide tube to the seat frame. During the crushing process, a portion of the headrest guide tube is bulged into a notch in the hole in the seat frame to prevent the guide tube from rotating with respect to the seat frame.
