Abstract: The present invention provides a method and apparatus for converting a fixed middle portion of a vehicle seat into a selectable seat back or arm rest. The apparatus is a "t-bar" which is inserted into the hollow tubing which supports the seat back. Once the t-bar is inserted, one leg is inserted into the remaining tubing sticking up from the lower seat portion to place the seat back in an upright position; another leg of the t-bar is inserted into the upright tubing to place the seat back in the arm rest position. A method is provided for converting the fixed seat back into a selectable upright or arm rest type device.
