The upper portion of the bed further comprises at least one comfort layer positioned adjacent to the fluid distribution member. The bed also includes a lower portion configured to support the upper portion and at least one fluid module configured to selectively transfer air to or from the fluid distribution member of the upper portion. In some arrangements, the fluid module includes a fluid transfer device and a thermoelectric device for selectively thermally conditioning fluids being transferred by the fluid transfer device.

Climate controlled bed assembly

According to certain arrangements, a conditioner mat for use with a bed assembly includes an upper layer comprising a plurality of openings, a lower layer being substantially fluid impermeable, at least one interior chamber defined by the upper layer and the lower layer and a spacer material positioned within the interior chamber. In one embodiment, the spacer material is configured to maintain a shape of the interior chamber and to help with the passage of fluids within a portion of interior chamber. The conditioner mat additionally includes an inlet in fluid communication with the interior chamber, at least one fluid module comprising a fluid transfer device and a conduit placing an outlet of the at least one fluid module in fluid communication with the inlet. In some arrangements, the fluid module selectively delivers fluids to the interior chamber through the conduit and the inlet. In one embodiment, fluids entering the chamber through the inlet are generally distributed within the chamber by the spacer material before exiting through the plurality of openings along the upper layer. The conditioner mat can be configured to releasably secure to a top of a bed assembly.

Climate-controlled topper member for medical beds

A climate-conditioned bed includes an upper portion having at least a first climate zone and at least one fluid module associated with such a first climate zone. The fluid module comprises a fluid transfer device for selectively moving a fluid and a thermoelectric device for selectively heating or cooling a fluid. The bed additionally includes one or more control modules configured to regulate the operation of the fluid module, at least one input device configured to allow an occupant to select a setting or mode associated with the first climate zone and at least a first temperature sensor configured to detect a temperature associated with the first climate zone of the thermally-conditioned bed. In some embodiments, the fluid module is operatively connected to the control module. The control module is configured to adjust at least one operational parameter of the fluid module based on, at least in part, the setting or mode selected by an occupant using the at least one input device, and the temperature detected by the first temperature sensor.

Control schemes and features for climate-controlled beds

According to some embodiments, a thermoelectric system includes a plurality of thermoelectric elements forming a thermoelectric array, the thermoelectric elements having a cooling side and a heating side. The system further includes at least one heat exchanger on at least one of the cooling side and the heating side, the heat exchanger being in thermal communication with at least some of the thermoelectric elements. In addition, the system includes a substrate generally positioned between the thermoelectric elements and the heat exchange element. The substrate comprises an electrical isolation layer, a support element configured to receive the heat exchanger and a plurality of interconnecting tabs configured to place adjacent thermoelectric elements in electrical communication with one another.

Segmented thermoelectric device

A seat portion or a backrest portion of seating assembly comprises a recessed area or wide groove along its exterior surface. The recessed area can be configured to receive a spacer (e.g., spacer fabric, member, module, etc.) that helps maintains the spatial and structural integrity of the recessed area. The spacer can be generally air and fluid permeable. In addition, a scrim layer can be positioned over the spacer fabric to help direct and/or distribute air or other fluid to an exterior surface of the seating assembly. The recessed area can also be configured to receive one or more films, occupant sensory devices, comfort layers, scrims, temperature sensors, heating devices and/or the like. Thus, air or other fluid can be delivered into the recessed area of a seat or backrest portion of a seating assembly, and subsequently delivered through the spacer fabric and scrim layer towards or away from an occupant. In some embodiments, the air or fluid is conditioned (e.g., heated or cooled) prior to entering the recessed area.

Fluid delivery systems for climate controlled seats

A climate controlled bed comprises a cushion member having an outer surface comprising a first side for supporting an occupant and a second side, the first side and the second side generally facing in opposite directions. In some embodiments, the cushion member includes one or more recessed areas along its first side or its second side. In one embodiment, the bed further includes a support structure having a top side configured to support the cushion member, a bottom side and an interior space generally located between the top side and the bottom side, the top side and the bottom side of the support structure generally facing in opposite directions, a flow conditioning member that may be at least partially positioned with the recessed area of the cushion member, an air-permeable topper member positioned along the first side of the cushion member and a fluid temperature regulation system.

Heated and cooled bed assembly

According to some embodiments, a climate controlled bed or other seating assembly comprises an upper portion or mattress having at least one fluid distribution member (e.g., spacer fabric) that is in fluid communication with the at least one internal passageway of the upper portion, wherein the at least one fluid distribution member is configured to at least partially distribute fluid within the fluid distribution member. In some embodiments, the internal passageway terminates at or near a bottom surface of the upper portion or mattress. The bed or other seating assembly additionally includes one or more inlays or interlays or intermediate layers, or components thereof, positioned between the upper portion and a foundation.

Climate controlled bed assembly with intermediate layer

Embodiments related to moisture abatement during a heating operation of a climate control system are disclosed. In some embodiments, the climate control system includes a thermoelectric device (TED) or other thermal condition device having a hot side and a cold side. In certain embodiments, the thermal conditioning device is operated (e.g., by a processor or a condensate switch) to inhibit or prevent the occurrence of condensation, and/or to abate condensation that has already occurred, on the cold side of the thermal conditioning device during the heating operation.
