Adjustable bed-chair

A mattress like formation composed of at least 6 adjoining individually inflatable chambers, formed, exept for the head or foot serving portions, by at least two chambers in every transverse alignement, and covered by flexible material, provided with a conduit and control system for individual adjustment, including a manuel or power and sequented rotary selector valve, linked to an exhaust and a fluid source under pressure such as an compressor.

An adjustable bed having a body supporting assembly resting on a panel and base and provided with inflatable bags which by inflation or deflation adjust the position of the occupant and cause the various movements of the body supporting assembly, the panel and base in relation to each other and including:

• (a) a conduit system connecting the inflatable bags individually to a fluid source through an individually adjustable valve system;
• (b) a source of fluid under pressure;
• (c) a control panel provided with the means to open the flow of fluid under pressure from the source in an adjustable manner to each inflatable bag individually and to exhaust therefrom.

An adjustable bed with with a first conduit system including a control valve for charging fluid under pressure selectively into, or exhausting fluid from the inflatable bags which adjust the position of the first panel relative to the second panel and the inflatable bags which adjust the back and leg supports relative to the second panel and the middle and leg supports relative to each other and a second system of conduits including a control valve for selectively charging air under pressure into or exhausting air from the inflatable bags of the mattress like assembly.

A body-supporting assembly and base between the body supporting assembly and the base member nesting on the floor, and the body supporting assembly mounted with its middle support section on that panel, and the position of the panel and the body supporting assembly adjustable in relation to the base by inflation or deflation of inflatable bags between the base and the panel, and

• (a) an inflatable bag placed between the panel and the back support at its pivotal connection to the middle support and operable under inflation or deflation for adjustment of said backsupport relative to said middle support;
• (d) a second inflatable bag placed between the panel and between said knee support at its pivotal connection to said middle support, and operable under inflation and deflation to adjust the knee support relative to the middle section;
• a third inflatable bag positioned below the leg support at its pivotal connection with the knee support, and operable under inflation or deflation for adjustment of the leg support relative to the knee support.

In a adjustable bed wherein the body supporting assembly is made up of 3 longitudinal sections, a center section and two side sections each pivotally connected to its side of the center section, the side sections being adjustable by power means such as inflation and deflation of the inflatable bags on which the respective sections rest.

In an adjustable bed wherein the body supporting assembly is made up of a middle section, two adjacent back sections pivotally connected to said middle section, two adjacent knee sections pivotally connected to the second side of the middle section, and two parallel leg sections pivotally connected to the second side of the knee section, and the body supporting - assembly covered by flexible material to bridge the gaps between the adjoining support-sections when they are adjusted separately for double occupancy and for individual limb positioning after surgery or treatment, the remote controlled adjustments of the individual supports being caused by means such as inflation and deflation of inflatable bags on which the respective sections rest.
