Abstract: A removable ladder rack assembly for removable installation in the bed of a pick-up truck or on a van comprising brackets positioned along one side of a truck bed or along both sides. The brackets are fastened to the truck and upright supports are removably locked to the brackets. Adjacent to the tops of the brackets are positioned inwardly directed extensible arms which extend over the bed.

Upward extensions on the upright supports and the arms help retain the ladders on the rack assembly.

Abstract: A protective seat for children traveling in a vehicle is provided with a visor that shields a child from excessive incident light and from flying objects in the event of a collision or sudden stop. Preferably, the visor is constructed of transparent, high-impact plastic that is tinted to reduce the amount of sunlight that can pass therethrough. The visor is U-shaped to have a central portion extending transversely across the protective seat and a pair of downwardly depending end portions mounted by a trunnion pin hinge to the lateral side edges of the child support shell. The position of the visor is pivotally adjustable and position lock elements and limit stops may be provided. The visor may be formed as original structure on the protective seat or as a retro-fit apparatus including mounting brackets that may be fastened to the protective seat thus providing the visor mounts.
