    IPC: A47C7/54

    Abstract: A seating arrangement includes a seat portion, a back portion, a support member caused to move between first and second positions, and a back recline lock arrangement that includes an actuator, a lock member caused to move between a locked position when the actuator is in an engaged position where the lock member prevents the support member from moving from the first position toward the second position, and an unlocked position when the actuator is in a disengaged position, and wherein the actuator is configured to move from the disengaged position to the engaged position when the chair back is in the reclined position, and the lock member is prevented from moving from the unlocked position to the locked position until the back assembly is moved from the reclined position to the upright position.
