The invention relates to an operating unit (10) for at least one electromotive adjusting drive (7, 8) of a piece of furniture (1), having:—at least one operating element (12, 13),—a transmission unit (16) for wirelessly transmitting signals on the basis of actuation of the at least one operating element (12), and—a rechargeable energy store (17) for storing electrical energy for supplying power to the operating unit (10). The invention is distinguished by the fact that it has a device (20) for inductively receiving energy for charging the energy store (17). The invention also relates to a control system for controlling at least one adjusting drive of a piece of furniture, and to a piece of furniture having such a control system.

An air mattress includes a first air cell, a second air cell, a plurality of third air cells, and a body-lifting air cell. The second air cell includes a first air chamber, a second air chamber, and a structurally-weakened region. The body-lifting air cell is below the second air cell and at least one of the third air cells. The body-lifting air cell is inflated by an air source controlled by a control system. When the body-lifting air cell is inflated, a vertical distance between the top of second air cell and the bottom of air mattress is greater than a vertical distance between the top of first air cell and the bottom of air mattress. When the body-lifting air cell is inflated, the second air cell has a lower structural strength than the other air cells to have a cushioning effect against external forces.

The disclosure relates to an adjustable bed and foundation thereof, in particular incorporating springs or other support elements into the adjustable bed foundation or frame. The adjustable bed can include one or more foundation spring support sections mounted on or in a mattress support surface of the bed foundation. Spring support sections having different firmness levels in different mattress support sections can provide a varying support level to a user of the adjustable bed foundation combined with a mattress thereon. Spring support sections that are discrete from each other can permit articulation of the corresponding mattress support surface sections without creating bending, elongation, and/or compression stresses which might otherwise cause uneven support from or damage to a continuous spring support element spanning multiple mattress support surface sections.

A patient turning device for a patient support apparatus. The patient turning device includes a first and second bladder assembly each including a plurality of layers and seals defining a bladder volume. The bladder volumes are selectively inflatable with fluid to expand the respective bladder assembly, and consequently move a patient support surface of the patient support apparatus. A portion of a lower layer of the first bladder assembly and a portion of an upper layer of the second bladder assembly define an overlapping region of the bladder volumes. The patient turning device is coupled to an underside of a carrier sheet and positioned between a crib assembly and a bottom cover. An augmenting feature is configured to resiliently expand as at least one of the first and second bladder assemblies receives the fluid to move at least a portion of the crib assembly away from a patient support deck.

A bed system includes a fixed frame, a movable frame, and first and second end boards disposed at the head and foot ends of the fixed frame, respectively. The system may be assembled and/or configured such that: a first electric or manual actuator is coupled between the fixed frame assembly and a first linkage assembly of the movable frame assembly for powered or manual movement of a first movable section of the movable frame assembly; a second electric or manual actuator is coupled between the fixed frame assembly and a second linkage assembly for powered or manual movement of a second movable section of the movable frame assembly; and/or a third electric or manual actuator is coupled between the first and second end boards for powered or manual height adjustment of the head and foot ends of the fixed frame assembly.

An electric mattress (1) includes a mattress frame (10) including a backrest section (101), a seat section (102), a thigh section (103) supporting a user's thighs, and a shank section (104) supporting a user's shanks, and a mattress cover (11) enclosing the mattress frame (10). The backrest section (101) and the seat section (102), the seat section (102) and the thigh section (103), and the thigh section (103) and the shank section (104) are rotatably connected, and angles between the backrest section (101) and the seat section (102), and between the seat section (102) and the thigh section (103) are able to be adjusted to predetermined angles.

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.

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.

An environmental control assembly has a case configured for attachment to a bottom surface of an articulation assembly. One or more inlet fans is attached to a first wall of the case. An inlet plenum receives air provided by the one or more fans and extends from the first wall to a central chamber. An outlet plenum extends from the central chamber to a second wall of the case. A first pair of outlet ports extends from the outlet plenum proximate the central chamber through side walls of the case and a second pair of outlet ports extends from the outlet plenum distal the central chamber through side walls of the case. A cylindrical flow diffuser is positioned in the outlet plenum between the side walls and controls airflow into the first pair of ports and second pair of ports, each of said outlet ports configured for attachment to one of a plurality of flexible air conduits.
