Hybrid coil and air chamber assemblies for cushioning supports generally include pressurized air chambers that are positioned intermediate strings of pocketed coils. In this manner, the coils and air chambers can move independently but can be made to cooperate to provide firmness control, contouring and/or support of a user thereof. Air pressure within the air chambers can be independently adjusted to manipulate firmness and/or contour properties in specific zones defined by the presence and location of the air chambers, e.g., pressure of the air chambers corresponding to the lumbar region can be adjusted to eliminate high pressure points. Still further, the pressure within the air chambers can be automatically adjusted to different applied loads as a function of movement. Also disclose are processes for adjusting a mattress including the hybrid coil and air assemblies.

A method for fabricating a custom anatomical cushion and a device to capture pressure controlled shape is provided. The device comprises, generally, a flexible membrane enclosing floating beads adapted to be completely immersed and freely moving inside a fluid. The device further comprises a mesh adapted to stop the floating beads from going outside of the flexible membrane as a result of a pressure increase or decrease inside the flexible membrane. The device is being fluidly connected to a pressure control system adapted to increase and/or decrease the internal pressure of the flexible membrane and comprises a vibration/leveling system adapted to adjust the fluid level inside the flexible membrane.

A method of supporting a body part (16), comprising providing a device (100) comprising: a first portion (105) configured to support a body part, wherein, in use, the body part applies a first pressure to the first portion in a first direction; means for detecting the first pressure; and a second portion (115) having means (212) for applying a second pressure to the body part in a second direction substantially perpendicular to the first direction; detecting the first pressure; determining the second pressure based on a user parameter; and applying the second pressure to the body part in the second direction at a pre-determined ratio relative to the first pressure using said means for applying the second pressure.

The present invention concerns an inflatable air cushion with at least one pressure indicator, the cushion including an outer side and at least one chamber, the at least one chamber made up of one or more films that are joined, thereby forming one or more airtight chambers, the cushion furthermore including a valve opening for connecting an air supply line, the valve opening being accessible from the surface of the cushion. The invention furthermore relates to a method of inflating such an inflatable cushion with pressure indicator. The new feature of a cushion according to the invention is that the pressure indicator of the cushion includes at least one strap with a first end and a second end, the at least one strap arranged in relation to the surface of the cushion, where the at least one strap is surrounding the cushion entirely or partially, and where the at least one strap is adapted such that the physical appearance of the strap is changed at a given pressure in the cushion, thus constituting a pressure indicator.

A mattress including: a support surface to support a user; a mattress main body that constitutes the support surface; at least one pressure sensor having a flexible sheet shape to detect a pressure acting on the support surface; a support surface cover positioned with respect to the mattress main body and arranged so as to cover the support surface; and at least one positioning member provided to the support surface cover to permit a movement of the pressure sensor with respect to the support surface cover in a planar direction while limiting an amount of the movement of the pressure sensor with respect to the support surface cover in the planar direction such that the pressure sensor is positioned on the support surface by the positioning member.

An air supply supplies air to multiple different inflatable devices. The air supply includes an air compressing device, and at least two pressure valves. The air supply operates to introduce air from the first pressure valve to a first inflatable device at a first pressure that is within a first air pressure range. The air supply also operates to introduce air, on demand, from the second pressure valve to a second inflatable device at a second pressure within a second air pressure range while continuing to supply air to the first inflatable device at a pressure within the first air pressure range. The second pressure and/or the second pressure range is different from the first pressure and/or the first pressure range.

A ball combination module capable of detecting and regulating a posture pressure has the requirement of regulating individual independent ball pressures and lifting and lowering functions and mainly includes one or multiple sets of pressure controlling ball modules. Each pressure controlling ball module is connected to a cylinder connected to an external pressure source and is configured with an independent inflating/deflating electromagnetic valve set including a pressure-sensing intake control electromagnetic valve of controlling inflation, a deflation control electromagnetic valve of regulating deflation and a pressure sensor. The external pressure source has a pressure regulator providing a stable pressure gas source. A main gas supply conduit connected to multiple shunts provides inflation and deflation for all the pressure controlling ball modules. The pressure controlling ball modules are combined to constitute a large-area support region and achieve the dot-like pressure regulating and lifting and lowering functions for the comprehensive single ball.

Active comfort controlled bedding systems include a variable firmness control and/or variable climate control. The active comfort controlled bedding systems generally include a plurality of air bladders, each one of the plurality of air bladders includes a pressure sensor configured to measure pressure within a respective air bladder. A control unit configured to selectively operate a pump and valves to sequentially adjust a pressure in two or more of the plurality of the air bladders having an applied load of an end user thereon to provide a repeating pattern within the two or more plurality of the air bladders, wherein the repeating pattern is defined by a pressure increase and subsequent decrease in a selected one of the plurality of the air bladders followed by a pressure increase and subsequent decrease in a selected other one of the plurality of the air bladders to provide a massaging action.
