Abstract
The invention described herein relates to a foam geometry which reduces the tendency of the child's head to slide forward and roll out by contouring the side foam to have its leading edge closer to the center line of the child's seat than some more rearward portion of the side foam thus forming an inward protruding forward lip on the foam. The depth of the protruding lip is the primary determinant of the increase in head retention, but the particular geometry of the lip, foam density or rigidity, and overall depth also contribute. The invention relates to the contour of a horizontal section of a headrest foam liner being closer to the seat centerline at some distance from the seat back than some distance closer to the seat back.
