Abstract
A child's car seat which includes a rigid, T-shaped shield member which forms the frontal restraint barrier across the chair structure. The shield member includes a lock mechanism between the vertical crotch member and the bottom of the chair structure which can be operated with one hand. The shield member is adjustably and rotatably affixed to the sides of the chair structure to permit rotation of the shield member above the child's head. Shoulder harness straps emanating from the back of the chair structure are automatically positioned as the shield member is lowered into place. The shield member, lock mechanism and shoulder harnesses are adjustable to accommodate infants and toddlers. The shoulder harness straps interact with the lock mechanism of the shield member such that once the lock is engaged, the shoulder harness straps cannot be adjusted.
