Narrative:

Captain's seat latching failed. Captain's seat slid back. Rejected takeoff. Callback conversation with reporter revealed the following information: the reporter stated that the seat moved aft as they taxied out; so the captain readjusted and checked the seat for security. It seemed secure; so the flight proceeded and the takeoff was attempted. When the seat moved aft; the captain transferred control of the aircraft to the first officer for the abort. After the reject; the aircraft returned to the gate; and maintenance cleaned and lubricated the latch mechanism. This apparently fixed the discrepancy; and the flight departed.
