Linear dual actuator for articles of lying or sitting furniture with at least two sections (2,3), which with one end is rotatably embedded in the article of furniture, and where each section (2,3) can be adjusted by means of an arm (5,7) on a rotary shaft (4,6). The dual actuator comprises a housing (8) with a recess (10) at each end for each of the rotary shafts (4,6) of the article of furniture and where the arms (5,7) on the rotary shafts (4,6) after mounting of the dual actuator on the article of furniture is positioned in the housing (8). At each end of the housing (8) there is a drive comprising an electric motor (11), which through a transmission (12) drives a spindle unit (13a) with a sliding element (19), one end of which is in engagement with the arm (5,7) for adjusting the sections (2,3). The dual actuator further comprises at least one printed circuit board (20) arranged in the housing (8), where the printed circuit board (20) is completely or partly surrounded by a heat shield (23) of metal. Thus, it is possible to provide a particularly low-cost dual actuator, as the housing can be made from an inexpensive plastic material without flame -retardant and where a great extent of safety against unintended fire due to an error in the printed circuit board (20) is still achieved.La présente invention concerne un double actionneur linéaire pour des articles de mobilier pour sallonger ou sasseoir comportant au moins deux sections (2, 3), qui, avec une extrémité, sont intégrés de façon rotative dans larticle de mobilier, et où chaque section (2, 3) peut être ajustée au moyen dun bras (5, 7) sur une tige rotative (4, 6). Le double actionneur comprend un boîtier (8) avec un évidement (10) à chaque extrémité pour chacune des tiges rotatives (4, 6) de larticle de mobilier et où les bras (5, 7), sur les tiges rotatives (4, 6) après montage du double actionneur sur larticle de mobilier, sont positionnés dans le boîtier (8). À chaque extrémité du boîtier (8) est dispos
