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 by means of the linear dual actuator. The dual actuator comprises a housing (8) with a drive at each end, which comprises an electric motor (11), which through a transmission (12) is in driving connection with a spindle (13). On the spindle (13) is arranged an activation element (14) with a spindle nut in engagement with the spindle (13), where the activation element (14) can be brought into engagement with the arm (5,7) for adjusting the sections (2,3). In case of power failure there is the problem that the back rest and leg rest section cannot be lowered to a plane level, which can make the bed uncomfortable or completely impossible to sleep in. This problem is solved in that a rotating element in the drives comprises a connection (21), which is accessible from the outer side of the housing (8) for connecting a tool, e.g. an Allen key (22) for driving the respective drives for the back rest and leg rest section (2,3) for lowering of these to a horizontal position.

There is provided a backrest pivoting system having a backrest and an actuator for pivoting the backrest. The actuator is pivotably connected to the backrest by a pivot defining a first pivot axis. The backrest is configured to pivot about a guide member which defines a second pivot axis coaxial with the first pivot axis. There is also provided a backrest pivoting system including an actuator and a resilient member mounted in series with the actuator. There is also provided an extendable user support assembly comprising a lower body support panel and a core support panel supported by a frame, the lower body support panel being translatable relative to the frame such that an opening is created between the lower body support panel and the core support panel when the lower body support panel is translated away from the core support panel. There is also provided a method for placing a bed in a vascular position.

An adjustable furniture such as a recliner chair or adjustable bed comprising a base, an intermediate support and a back support. Both the intermediate support and the back support are guided for movement relative to the base by a second guide means while the base moves along a first guide means. The first guide means include at least one guide associated with one of the base and intermediate support and at least one follower associated with the other of the base and intermediate support. The second guide means includes at least one guide associated with one of the base support and the back support and at least one follower associated with the other of the base support and the back support.

A modular adjustable bed includes a bed frame unit, front and rear sliding frames disposed to be slidable on the bed frame unit, a head support frame pivotally mounted on the front sliding frame, a pair of prop links coupling the head support frame to a front frame of the bad frame unit, and a leg support frame pivotally mounted on the rear sliding frame. When the head support frame is driven to be displaced to a head elevated position from a head normal position, the front sliding frame is displaced to a front position from a rear position. The leg support frame can be driven to move from a leg normal position to a leg elevated position.

A sleep system comprises an air posturizing module having a case, the case comprising a first case section extending medially along a length of the case to define a movable first section, a second case section adjacent to the first case section and extending along a length of the case to define a movable second section, a third case section defining a third posturing section, a fourth case section extending medially along a length of the case to define a movable third section, and a fifth case section extending medially along a length of the case to define a movable fourth section. One or more first air chambers are carried in the first, third and fourth case sections to provide a first sleep area, and one or more second air chambers are carried in the second, third, and fifth module sections to provide a second sleep area.
