A lap belt for the passenger restraint system is used to maintain the shield in position on the base and also to form a direct restraint on a child in the seat. A shoulder belt adjustment strap is also provided for positioning a shoulder belt of the passenger restraint system downwardly away from a child's head and neck area when the base is used without the shield in place. The adjustment strap may be positioned to extend upwardly along either side of the booster seat to facilitate use of the booster seat with passenger restraint systems on either a right or left side of a vehicle.
