Linear dual actuator for lying or sitting furniture having at least two sections (2,3), which with one end is rotatably embedded in the article of furniture and where each section (2,3) with an arm (5,7) secured to a pivot shaft (4,6) can be adjusted. The dual actuator comprises a housing (8) with a recess (10) in each end for each of the pivot shafts (4,6) on the article of furniture and where the arms (5,7) on the pivot shafts (4,6) after the dual actuator has been mounted on the article of furniture reach into the housing (8). Each end of the housing is furnished with a drive comprising an electric motor (11), which through a transmission (12) drives a spindle (13a) with a thrust element (18) having one end in engagement with the arm (5,7) for 'adjusting the sections (2,3). The electric motors (11) are located axis-aligned with the respective spindles (13a). Thus, the housing (8) can be constructed as a flat box with a relatively low height, as the only thing which should be considered in terms of the height is the thickness of the electric motors and not their length. As the housing (8) can be constructed as a flat box without bulges and indentations the mould is thus also relatively uncomplicated.
A linear dual actuator dedicated for lying or sitting furniture of the type comprising at least one section (2,3), which with one end is rotatably embedded around an axis in the article of furniture, and where the section (2,3) can be adjusted by means of a pivot shaft (4,6) directly or indirectly connected to the section (2,3), and where an arm (5,7) is secured to the pivot shaft (4,6) by which the pivot shaft (4,6) is brought to rotate and thus adjust the section (2,3), said dual actuator comprises a housing (8) with a recess (10) in each end for each of the pivot shafts (4,6) on the article of furniture, and where the arms (5,7) on the pivot shafts (4,6), after the dual actuator has been mounted, reach into the housing (8), and where each end of the housing (8) is furnished with a drive comprising an electric motor (11) a transmission (12) in driving connection with the electric motor (11), a spindle unit (13) in driving connection with the transmission (12), which spindle unit (13) comprises a spindle (13a) and a spindle nut (13c) as well as a thrust element (18) in connection with the spindle unit (13), and where the thrust element (18) is guided in the housing (8) secured against rotation, and which can be brought into engagement with the arm (5,7) for adjusting the section (2,3), wherein the electric motors (11) are located inside the housing parallel with the respective spindles (13a).
