Abstract
Abstract An automobile car seat for a child is provided with a tray which is pivoted slightly above and behind the shoulders of the child who is to sit in the seat. Shoulder and lap straps are secured to the pivoted tray structure so that as the tray is swung down into position, the shoulder and lap straps automatically come into position to hold the child in place. The tray is provided with a large padded center post which locks into position into the chair seat as the tray is swung forward into position. As the child gets older and bigger, the position of the shoulder straps may be raised and locked into their new position. The seat and back may be tilted as a unit by raising the front of the seat, so that the child can lean back and sleep.
