ABSTRACT:
Headrest-mounting-tubes are attached into the seatframe of an automotive seat. Headrest-posts engage the mounting-tubes, and support the headrest. The headrest-posts need to be orientated correctly, and so have a key that engages a keyway in the mounting-tube. The keyway is formed as a keyway-pocket, being punched from the open end of the tube. Preferably, the keyway-pocket is punched after the mounting-tube has been attached into the seatframe.
