Abstract: A child car seat can include a seat base and a seat shell. The seat shell can include a seat bottom and a seat back along a front side of the seat shell. Shoulder straps can be provided to assist holding a child in place in the car seat. The shoulder straps can extend through openings in the seat back of the seat shell and can be coupled to a splitter plate positioned along a back side of the seat shell. The splitter plate can include a slot for receiving a tightening strap and a roller or radiused edge positioned adjacent the slot to help the tightening strap slide along the roller or radiused edge when tension is applied to it. The tightening strap can be routed through the slot and under the seat shell and can pass through another slot along the seat bottom to tighten the shoulder straps.

Abstract: A child safety seat can include a seat back and a seat bottom. The seat back can be fixedly, removably, and or rotatably coupled to the seat bottom. The seat back can include an adjustable head rest that moves vertically with respect to the seat back. The head rest can include a headrest latching mechanism for adjusting the vertical position of the headrest with respect to the seat back and a fold locking mechanism to selectively position the head rest and lock the seat back orientation in a raised position for use or a folded position for carrying or storage. The head rest can include a single adjustment actuator, such as a pushbutton or lever, to actuate both the latching and locking mechanisms with a single hand for selectively adjusting the headrest position and seat back orientation.
