Abstract: A seat heater includes a substrate. A formed heating wire is disposed on the substrate. A sewing thread attaches the formed heating wire to the substrate. A method of fabricating the seat heater includes forming a straight heating wire into a formed heating wire having miniature wave shape, feeding the formed heating wire onto a substrate, and attaching the formed heating wire onto the substrate by sewing a thread.

Abstract: An air conditioning unit includes a shaped body forming at least one part of a seat cushion. The shaped body has a seating surface and an opposite lower side. An air flow module is arranged at the lower side of the shaped body. The air flow module includes an air mover and has an air inlet opening and an air outlet opening. The shaped body has at least one air through-hole extending from the seating surface to the air flow module. The air flow module is in fluid communication with the at least one air through-hole in the shaped body. At least one channel extends in a radial direction adjacent the lower surface of the shaped body. The air flow module is in fluid communication with the at least one channel, and provides airflow between the seating surface of the shaped body and the at least one channel.

Abstract: An air manifold includes a sheet-like body including first and second spaced, opposing walls and a sealed perimeter. A plurality of divider walls connects the first and second walls together and defines a plurality of air channels within the body. An opening in the body defines an air port cooperable with an air mover. The air port is in fluid communication with the air channels. At least one zone inside the body is free of the divider walls. A group of the air channels are in fluid communication with each other through one the zone. A plurality of air vents located in the first wall are in fluid communication with at least one of the air channels. The air manifold is disposable between a seat cushion element and a structural support of a seat. The first wall of the air manifold faces a backside surface of the seat cushion element.

Abstract: A ventilation diffuser bag for disposition on a vehicle occupant support includes a perforated, occupant facing side and an opposite non-perforated, support surface facing side. The non-perforated side includes an opening to allow air flow into the diffuser bag. An air mover support integral with the non-perforated side includes an endless sidewall extending from the opening for providing support for an air mover. The endless sidewall includes a retaining edge spaced from the non-perforated side for suspendably retaining the air mover within the air mover support. The non-perforated side of the diffuser bag is supportable on an occupant facing surface of a vehicle occupant support, and the air mover support extends into the occupant support.

Abstract: A modular comfort assembly is disclosed. The modular comfort assembly is adapted for installation within an occupant support. The occupant support includes a surface, which has a recess therein. The modular comfort assembly includes a ventilation diffuser allowing for flow of air through the diffuser. The diffuser has an outer edge sized to extend over and cover a perimeter of the recess. The modular comfort assembly also has a heating element adapted for placement on a surface of the diffuser.

Abstract: A modular comfort assembly adapted for installation within an occupant support includes a ventilation diffuser bag allowing for circulation of air through the bag. The diffuser bag includes a side surface having perforations therein and an opposite non-perforated side. The modular comfort assembly further includes a heating element and a lumbar support system. The heating element is adapted for placement on the surface of the diffuser bag having the perforations therein. The lumbar support system is adapted for placement on the non-perforated side of the diffuser bag.

Abstract: A method of installing a modular comfort assembly within an occupant support includes the step of providing a modular comfort assembly including a heating element and at least one of a ventilation diffuser bag and a lumbar support system, the heating element, the diffuser bag, and the lumbar support system being modularly attachable to each other on sides thereof. The occupant support includes an outer cover, an internal foam bun, and a frame. The method further includes the step of mounting the modular comfort assembly onto a surface of the foam bun beneath the outer cover.
