A child restraint seat is shown having a system for tightening the safety harness belt that includes an adjuster plate with the adjuster plate being slidably mounted on a guide track on the back side of the restraint seat. The adjuster plate includes a belt tensioning portion that contacts the safety harness belt at various positions between two opposite fixed ends of the safety harness belt. Movement of the adjuster plate along the guide track on the back side of the restraint seat causes the belt tensioning portion of the adjuster plate to change the slack length of the safety belt by an amount approximately equal to two times the distance which the adjuster plate is moved along the guide track. A pawl is part of the adjuster plate assembly and is biased into contact with teeth on the guide track to hold the adjuster plate in a predetermined position along the guide track.
