摘要:
Environmentally conditioned furniture, such as a bed (10), has a permeable mattress (12) or cushion set upon a plenum chamber base (11), with ventilator fan (13), distribution duct (65) and heater (64), co-operatively disposed to intake ambient air and expel conditioned chamber air through the mattress (12) under temperature and so relative humidity control, for comfort and/or respiratory benefit of a bed occupant; a particular construction employs a shallow unitary moulded tray as a plenum module (135) between mattress and base frame, with self contained conditioner unit (140).

A cushion pad 10 for an automobile seat or a mattress has an internal plenum 16 connected to a heat pump 44 through an air inlet duct 42. The bottom and sides of the plenum 16 are covered with an air impervious layer 14. The top of the plenum is covered with an air permeable layer 20. The plenum 16 is formed as a plurality of tubes arranged side by side in a single layer. The walls of the tubes are formed as an open weave of monofilaments 36 so that pressurised conditioned air from the heat pump 44 passing into the plenum 16 through the air inlet duct 42 can pass along the tubes with a relatively low back pressure and transversely through the walls of the tube and through the air permeable layer with a higher back pressure.

A device for ventilating chairs comprises an air-permeable covering portion (13, 14) which is applied over the filling (7) of the chair, an insert (15; 59) located between the covering portion and the filling and a suction device (26) which through a system of suction openings in the covering (57, 60) and the insert (40, 56) evacuates the ventilating air. According to the invention the insert (15) is joined with the covering (9) of the chair to an integrated unit, which is tightened against the filling (7), and from the insert (15) there extends a duct connection (40, 25) tightly separated from the filling, which leads the air to the suction device.

A fan device which is built into a vehicle chair, and is arranged to ventilate away air that is drawn through the covering and filling of the vehicle chair, comprises an electrically driven fan (9) of radial type attached at the bottom of the chair. The fan wheel (17) extends from the driving cover (14) of the motor (13), which extends up into the inlet (30) of the fan. The fan (9) shall be attached to a carrying means (39) in the chair which is located on the underside of the filling (40) and has passages (65) for the ventilating air adjacent to the fan inlet.
摘要:
A forced flow-guiding device having perforated mesh surface branched guiding tubes and, in particular, a perforated mesh-like, flexible, flat surface structure (1) having a set of single or double faces, a set or more than one set of hollow guiding manifolds comprising main and branch manifolds being disposed on one surface or between sandwiched layers. A fluid pump (24) is disposed on one end of the main (22) tube and the guiding manifolds are provided with a plurality of suitable fine holes (25), fluid of suitable pressure being pumped into the guiding manifolds by the fluid pump, causing the fluid to produce a uniform pressure and to flow uniformly out from said fine holes (25) and the mesh-like flat surface structure (1).

A lounger chair accommodating an occupant in a reclining position while exposing him to a stress-relieving environment, includes a couch (10) whose frame supports a bed formed by an array of parallel dowels contoured to define an intermediate posterior region having extending therefrom a front thigh and leg region and rear back and head region. The bed contour is adjustable to conform to the natural contours of the occupant. The couch is mounted on a base (11) and is angularly adjustable thereon. Supported on the frame below the bed is a water trough (38) contoured to define an intermediate sump section (39) having extending therefrom front and rear waterfall sections, each provided with a set of deflectors so situated as to cause the flowing water to cascade into the sump section. Coupled to the trough is a pump (42) supplying water to the input of the front and rear waterfall sections, the water collected in the sump section being returned to the pump and recirculated. The sounds emanating from the trough simulate those of a running brook, these sounds together with mist and negative ions arising from the trough passing through spaces between the dowels of the bed to envelop its occupant in a stress-relieving environment.
摘要:
A body-supporting device forming the seat (1) and/or the backrest (15) of a chair and adapted to avoid sweating caused by the thermal insulation of the chair is characterized by the fact that at least those sections (2) of the exterior surface of the device that form the support surfaces for parts of the body of a person sitting in the chair are made of air-permeable material. At least one opening (11) to the exterior is arranged in said device to communicate with the interior side of said air-permeable sections (2). A suction device capable of producing a negative air pressure, such as a suction turbine, may be connected to said opening. The interior of the body-supporting device is so arranged that, when a suction device is thus connected and is running, air that is exterior to said support surfaces will be drawn through the air-permeable sections (2) and via the interior of the body-supporting device and out of it through said opening (11), in order to remove heat radiated by the body of the person, in particular from the region between said parts of the body and the air-permeable sections, and to cool the latter by means of the airstreams thus created.
摘要:
Die Erfindung betrifft einen Sitz mit einem Schaumkern (4) und einem Überzugsmaterial (14), der dadurch gekennzeichnet ist, daß ein wesentlicher Teil der der Sitzfläche (5) zugewandten. Seite des Schaumkerns (4) mit einer luft- und wasserdurchlässigen Schicht (11) abgedeckt ist und daß auf der der Sitzfläche zugewandten Seite des Schaumstoffkerns (4) bzw. von dieser Fläche aus durch den Schaumstoffkern (4) verlaufende Rillen (9) und/oder Kanäle angeordnet sind, die sich bis zu einer oder mehreren der übrigen Außenflächen des Schaumkerns (4) erstrecken, wobei die Rillen (9) undioder Kanäle auch nach Kompression des verwendeten Schaumkernmaterials noch einen Luft- und Wasserdampftransport ermöglichen. Der mehrschichtige Aufbau des Sitzes soll auch nach mechanischer Belastung eine Wasserdampfdurchlässigkeit von mindestens 10.000 g'm 2 . 24 h besitzen.
摘要:
Ein Sitz eines Nutzfahrzeugs soll einerseits wasserdicht und anderseits luftdurchlässig sein. Es weist hierfür eine ein Gewebe tragende dichte Kunststoffolie oder Latexschicht Löcher auf, die nur bei Belastung des Sitzes offen sind. Vorzugsweise wird bei Belastung aus einer Luftkammer Luft durch die Löcher gedrückt.
