Abstract: A modular package tray for an automotive vehicle, comprising: a generally hollow, generally rectangular plastic housing 10 having an interior cavity 12, opposed upper and lower wall sections 14/15, opposed forward and rearward longitudinal edges 16/17, and opposed left and right lateral edges 18; and left and right wing sections 20 each attached to a respective one of the left and right lateral edges 18 by a living hinge 30 integrally molded with the plastic housing. Each of the wings 20 may be folded about its respective living hinge 30 in order to temporarily reduce the overall length of the package tray, thus permitting the package tray to be easily installed or removed through the rear window of the vehicle. The package tray may further include a center high mount stop light 60, in-molded carpet 40 generally covering the upper wall section 14, and one or more audio speaker assemblies 52.
