A plastic panel assembly for use in a vehicle is provided including a sheet metal frame constructed and arranged to be coupled to a vehicle and a plastic panel mounted to the sheet metal frame. The plastic panel includes a plurality of pin members extending from a surface thereof and the frame includes a plurality of openings therethrough such that one pin member is disposed through an associated opening. Fastening structure is constructed and arranged with respect to the pin members to retain the plastic panel to the frame so that the panel is prevented from moving relative to the frame in a direction of extension of the pin members while the panel is permitted to move relative to the frame in a direction transverse to the direction of extension of the pin members, upon thermal expansion of the panel.

[ What is claimed is:] [1.]1. A method of compensating for thermal expansion and contraction of a plastic panel structure mounted to a frame structure, said frame structure having a coefficient of thermal expansion less than that of said plastic panel structure and defining a central opening therein being disposed in a plane, said plastic panel structure being disposed with respect to said frame structure so that a marginal peripheral portion of said plastic panel structure extending generally in the direction of extent of said plane is coextensive with a marginal peripheral portion of said frame structure and a central portion thereof extends in covering relation with said central opening, the method including:providing a series of at least three pin and slot connections extending operatively between the coextensive peripheral portions of said plastic panel and frame structures and disposed in spaced relation therealong for retaining the coextensive peripheral portions of said plastic panel and frame structures together, each of the at least three pin and slot connections including a slot formed in one of said plastic panel and frame structures and a pin provided on the other of the plastic panel and frame structures, each said pin extending transversely through a respective slot formed in said one of said plastic panel and frame structures, each said slot having a longitudinal axis extending in a direction toward a common point disposed within said central opening,preventing relative movement of said pins within respective slots along said plane in one direction within which the at least three pin and slot connections are disposed while allowing relative movement of said pins within respective slots along said plane generally in directions away from and toward said common point, andenabling the plastic panel structure to expand and contract with respect to said central opening in response to changes in temperature within a range of operating temperatures while providing a stable connection in any direction along said plane between the coextensive peripheral portions of said plastic panel and frame structures throughout the range of operating temperatures.
