Abstract: A shutter link (1) for a multi-link overhead shutter or roller blind comprises two sheet metal sheets (7, 8) formed with a cavity (3) between them. The cavity is filled with a heat insulative compound (4) and hinge formations (5, 6) are provided along the longitudinal side of the sheets. Slots (9) are formed along the length of each shutter link on one wide side thereof. The slots are bridged by narrow webs (11) defined by slot interruptions and flanges are provided along the slots on their side facing the cavity with notches (15) formed adjacent to the bending lines and extending parallel to the slots.

Abstract: For the purpose of manufacturing a shutter link for an overhead shutter or a multi-link roller blind, two metallic sheet-metal shells are made which are provided at their ends with hinge elements of claw-like shape. In order to avoid undesirable deformation during the operation of joining the metallic sheet-metal shells together, such deformation being particularly apt to occur in the vicinity of the narrow sides, it is intended to provide the two shells with longitudinally extending beads adjacent to the two hinge elements.
