Novel flexible hinge (70) assemblies for connecting abutting panel sections (30, 50) of upward acting doors, such as garage doors, are disclosed. More particularly, abutting panel sections of an upward acting door are hingedly con- nected together economically and in a weather-tight relation- ship by a flexible hinge (70) assembly which can be easily in- stalled without the use of tools by snapping it into prede- signed elongated slots (55, 35a) in the abutting panel sections (30, 50) from the rear or interior side of the door. Exemplary of a novel hinge assembly in accordance with the present in- vention comprises an elongated flexible hinge (70) having first (73) and second (74) arm flanges connected to a central web (72) formed with a material substantially resistant to flexure fatigue and two elongated slats (90) wherein each flange (73, 74) is adapted to be inserted into one elongated slot (55, 35a) along the abutting edge of one abutting panel section and each slat (90) is likewise adapted to be inserted into one of the elongated abutting slots in contact with one of the arms inserted therein to lock the flexible hinge (70) in the elongated slots and hingedly connect together the abutting panel sections (30, 50) for articulation with respect to each other.
