A roller shutter slat has hollow sectional slats (1) with a central part (1c), two edge parts (1a) and transverse grooves (1b) arranged therebetween for receiving bearing or adjusting links (3,4). The edge parts (1a) and the central parts (1c) are spaced apart and interconnected by linking elements (5, 6, 40, 41) inserted into hollow chambers (26) of the hollow sectional slat (1). The cross-section of the linking elements (5, 6, 40, 41) is narrower than the cross-section of the hollow chambers (26) and the linking elements (5, 6, 40, 41) are linked to the hollow sectional slats (1) by tongue-and-groove joints (9, 10; 42, 43). Easy-to- produce grooves (1b) are thus created without weakening the roller shutter slat (1) in the area of the grooves (1b).

Un volet roulant comprend des lattes profilées creuses (1) avec des rainures (1b) transversales de réception de maillons de support ou d'ajustement (3, 4) situées entre une partie médiane (1c) et deux parties marginales (1a). Les parties marginales (1a) et les parties médianes (1c) sont mutuellement espacées et reliées les unes aux autres par des éléments de liaison (5, 6, 40, 41) insérés dans des chambres creuses (26) de la latte profilée creuse (1). La section transversale des éléments de liaison (5, 6, 40, 41) est plus étroite que la section transversale des chambres creuses (26) et les éléments de liaison (5, 6, 40, 41) sont reliés aux lattes profilées creuses (1) par des languettes et des rainures (9, 10; 42, 43). On obtient ainsi des rainures (1b) faciles à produire, sans que la latte (1) pour volets roulants ne soit affaiblie dans la zone des rainures (1b).
