Abstract: A sunshade assembly for use with a child or infant safety car seat has a canopy mounted on a plurality of ribs pivotably carried at respective ends of a base portion on which the car seat may be positioned. The base portion is formed from a pair of transversely extending brackets adjustably connected together so that the base may be expanded or contracted to receive car seats of varying widths. A transversely elongated slot in one of the brackets permits the brackets to be adjustably connected together. The ribs are formed from tubular members which securely receive and grip tangs in the ends thereof, the tangs being formed integral with disks which overlay each other at the respective ends of the brackets and are pivotably connected to upstanding walls at the exterior ends of the brackets.
