The support structure 10 can adjust to body force concentrations on a body of a person 30 lying on the bed by adjusting the pressure of one or more air bladder cells 22. Each air bladder cell 22 can be sealingly joined at edges thereof to form a hermetically sealed body. Each air bladder cell 22 can be a laterally elongated, rectangular shape and can be made of a thin sheet of a flexible, elastomeric material such as neoprene rubber or polyurethane, having a thickness of about 0.014 inch. The side and end panels of each air bladder cell 22 can be sealingly joined at edges thereof to form a hermetically sealed body which has a hollow interior space. Optionally, each air bladder cell 22 may be fabricated from a tubular preform in which each end panel is sealingly joined to opposite transverse ends of the tubular preform. In either embodiment, adjacent panels of an individual air bladder cell 22 can be sealingly joined by a suitable method such as ultrasonic bonding, RF-welding or adhesive bonding.
The number, size, shape, thickness, relative positioning and spacing of air bladder cells 22 of can be varied as desired. As depicted in
The support structure 10 can provide support to a person in discrete support zones, with each zone being associated with a targeted portion of the person's body. In an example, a support structure 10 can provide for adjustable support in one or more of a head zone, a shoulder zone, a lumbar zone (upper and/or lower), a hip zone, and a foot zone. Each column of air bladder cells 22 can span a plurality of zones. For example, from three to six zones can be arranged, corresponding to locations along the major curvature of a longitudinally disposed medial section of a typical human body. As depicted in an example embodiment, as shown in
In another representative embodiment, as depicted in
One or more of the air bladder cells 22, including at least one air bladder cell 22 per support zone 50, can be provided with an air inlet port 24 which can protrude through a side wall, e.g., a left or right side wall, and provides for fluid communication with a hollow interior space within the air bladder cell 22. Air admitted into or exhausted from hollow interior space through an air inlet port 24 of an air bladder cell 22 enables the air bladder cell to be inflated or deflated to a selected, predetermined, or adaptively changed pressure.
Although the shape of each air bladder cell 22 of can be that of a rectangular block, or parallelepiped, the air bladder cells 22 may optionally have different shapes, such as convex hemispheres protruding upwards from the base of the cushion.
Referring now to
Each air inlet port 24 of an air bladder cell 22 can be operatively connected to the air pressure controller 100, which can provide fluid, e.g., air, communication into the air bladder cells 22 via one or more inlet tubes 110, such as inlet tubes 110A-110D shown in

Thus, as can be understood from the description herein, a bed utilizing the systems and apparatuses of the support structure 10 of the present disclosure can include a support structure 10 having a plurality of zones 50 of support, the zones being associated with portions of the human body, such as the head, shoulders, lumbar, hips, and feet. The number of zones 50 can be, for example, between two and ten, or between three and six. Each zone 50 can have associated therewith one or more air bladder cells 22. In an embodiment, all the air bladder cells for a single zone 50 are operationally connected to the air pressure controller 110 by an inlet tube 110. Thus, in general, there can be one inlet tube 110 for each zone 50. In an embodiment, a bed of the present disclosure can have five air bladder cells 22 and four zones 50; or ten air bladder cells 22 and six zones 50.

The pliable manifold 122 is shown in more detail in
As can be understood from the above description, a support structure 10 can benefit from the features and components of the air pressure controller 100, which provide for effective air bladder cell inflation while also minimizing noise and vibration. By “ganging” a plurality of air pumps 120 into a single manifold, for example, an effective amount of air (measured, for example, in cubic feet per minute) through pliable manifold 122 to solenoid valves 124, can be moved in a variable, quiet manner. When initially filling the air bladder cells 22, for example, all of the plurality of air pumps 120 can be energized and utilized. During use, less than all of the plurality of air pumps 120, including one air pump 120, can be utilized to maintain, change, or otherwise alter the pressure in any given air bladder cell 22. Because each air pump 120 feeds into a single pliable manifold 122, any or all of the air pumps 120 can be used to provide air to any of the solenoid valves 124. Using low voltage DC air pumps reduces noise and vibration as well as increases safety to a user. Further, noise and vibration can be reduced due to the variably reduced use of air pumps 120, as well as the noise and vibration isolation mounting when integrated into the housing 112, as described above. Additionally, by essentially “cross-connecting” each of the air pumps 120 to any of the solenoid valves 124, air flow to any or all of the inlet tubes 110, and eventually the air bladder cells 22 can be optimized and/or maximized.
The pliable manifold 122 offers numerous advantages to the operation of the air pressure controller 100. In an embodiment, the pliable manifold 122 can be made of rubber, flexible plastic, and/or silicone. The pliable manifold 122 reduces noise, reduces vibration, minimizes or eliminates water or chemical damage, and can reduce costs to make and use. The pliable manifold 122 can have incorporated therein or thereon a pressure relief valve 136. The pressure relief valve can be a safety feature that can serve as an emergency relief valve in the event of an over-pressure condition. The pressure relief valve 136 can be a Venturi valve that, in addition to permitting air release there through, also provides an audible signal, such as a whistling sound, upon activation or operation.
In some embodiments, the air pressure controller 100 can be attached or otherwise positioned proximate to a foot or distal portion of the support structure 10. However, it should be appreciated that the air pressure controller 100 can be attached or positioned in other locations relative to the support structure 10 (e.g., a side, a head portion of the support structure 10, the floor, attached to a wall, etc.). The air pressure controller 100 can be encapsulated with foam or other dampening material. In some embodiments, the air pressure controller 100 can selectively pump air to (and in some embodiments from) one or more air bladder cells 22 on a single side of the support structure 10 or multiple sides of the support structure 10. For instance, in embodiments (not shown) in which a first air pressure controller 100 selectively pumps air to air bladders cells 22 located in a first side of the support structure 10, a second air pressure controller 100 can be utilized to selectively pump air to air bladder cells 22 located in a second side of the support structure 10.
In an embodiment, a support structure 10 in the form of a bed can be configured as described with reference to
The plurality of sensors 192 can detect localized pressure, and transmit the localized pressure data to the control board of the air pressure controller to respond, if necessary by executing instructions to vary the amount of air in one or more air bladder cells in the zone of the detected localized pressure. In an embodiment, a person 30 can predetermine, such as by pre-programming, one or more desired pressure profiles for the support structure 10. A pressure profile can be set for each of various sleeping positions, such as on the back or on the side. By the system disclosed, real-time, feedback-controlled response of the air pressure controller to increase or decrease the amount of air in one or more air bladder cells 22 can redistribute the air pressure to reshape the bed in response to, for example, a person turning from her back to her side. For example, it may be that more inflation of the air bladder cells 22 in the back zone 50 is desirable, and less inflation of the air bladder cells 22 in each of the hip zone 50 and shoulder zone 50, when a person rolls onto her side from her back. Such redistribution of inflation of air bladder cells 22 can be achieved by suitably linking the plurality of sensors 192 with control components of the air pressure controller 100 to sense, respond, and provide feedback in a loop that operates to provide for the pre-determined inflation levels. The distribution of inflation of air bladder cells 22 can thus be constantly monitored for each zone, with adjustments automatically made while the person 30 sleeps.
The air pressure controller 100 can draw in air from outside the bed through any suitable pathway, including, by example, through an air duct 119 having an opening outside of the bed, including any foam padding. Likewise, the air pressure controller 100 can be placed such that the control panel 140 faces exteriorly to the bed, as indicated in
As can be understood from the example embodiment of
In an example embodiment described with reference to
In addition to the components and features described above, the air pressure controller 100 can be operationally configured to generate, gather, and/or transmit data and reports related to sleep time, sleep comfort, and sleep quality. For example, data related to sleep activity can be gathered and stored in cloud based storage. Such data can include, for example, data related to sleep comfort, sleep cycle, pressure distribution, respiration, heart rate, body temperature, and the like. Likewise, other data related to the sleep environment can be gathered, analyzed, and/or transmitted, including, for example, room lighting, room temperature, bed temperature, noise levels, and the like. In some embodiments, such data can be processed and reports can be generated locally by the air pressure controller 100 and then transmitted to a user's connected device for display. In other embodiments, data processing and report generation can be performed by one or more remote computing devices (e.g., remote servers, etc.) or remote computing services (e.g., cloud services) and delivered to the user's connected device for display. In such embodiments, the air pressure controller 100 can be configured to transmit sensor data and operational data to the remote computing devices/services for analysis and report generation. It should be appreciated that portions of data processing and report generation can also be performed by a combination of the air pressure controller 100 and a remote computing device/service, in some embodiments.
