A ventilation or heating/cooling element and a ventilation or heating/cooling clothing item

Abstract

A ventilating or heating/cooling element having a first side having an air permeability of 15-800 m 3 /m 2 /h at 120 Pa. The first side is for directing an air flow toward a person. The ventilating/cooling/heating element may form or form part of a mattress, a duvet/blanket, a pillow, a sleeping bag, a seat, a clothes item or the like. A pump may be provided for providing air into the ventilating/cooling/heating element, or one or more openings may be provided for receiving air when a person is moving, such as when riding a motor cycle.

         16 . An inflatable ventilation or heating/cooling element comprising a first side, a second side and an air inlet, the first side having an air permeability of 15-800 m 3 /m 2 /h at 120 Pa. 
     
     
         17 . An element according to  claim 16 , wherein the second side is at least substantially air impermeable. 
     
     
         18 . An element according to  claim 16 , wherein, in the first side, one or more first areas and one or more second areas are provided, the first and second areas not overlapping, where the first area(s) have a larger air permeability than the second area(s). 
     
     
         19 . An element according to  claim 18 , wherein the first and second areas comprise a woven or nonwoven material and wherein the first areas further comprise one or more openings or channels through the material. 
     
     
         20 . An element according to  claim 16 , further comprising a pump for providing air to the air inlet. 
     
     
         21 . An element according to  claim 16 , the element comprising one or more element defining a maximum distance between a part of the first side and the second side. 
     
     
         22 . An element according to  claim 16 , further comprising a spacer element provided between the first and second sides, the spacer element being configured to allow air to flow there through during compression thereof. 
     
     
         23 . An element according to  claim 22 , forming one or more of:
 a mattress, where the first side is directed upwardly,   a pillow, where the first side is directed away from a central portion of the pillow and/or   part of a seat or chair, where the first side is directed away from a central portion of the seat/chair and toward a position of a sitting person.   
     
     
         24 . An element according to  claim 16 , forming part of a duvet or blanket, the first side directed away from a central portion of the duvet/blanket. 
     
     
         25 . An element according to  claim 16 , forming part of a sleeping bag comprising a sleeping cavity, the first side directed toward the sleeping compartment. 
     
     
         26 . A clothing item adapted to be worn by a person, the clothing item having a ventilating/cooling/heating element having an inner surface and an outer surface defining there between a volume into which one or more air inlets may guide air, the inner surface having an air permeability of 15-800 m 3 /m 2 /h at 120 Pa. 
     
     
         27 . An item according to  claim 26 , wherein the outer surface is air permeable or at least substantially air impermeable. 
     
     
         28 . An item according to  claim 26 , wherein an air inlet comprises an opening through the outer surface and is positioned on a front of the clothing item when worn by a person. 
     
     
         29 . An item according to  claim 26 , further comprising an air pump configured to provide air through the inlet(s). 
     
     
         30 . A method of operating an element or an item according to  claim 16 , wherein air is fed to between the inner/first surface and the second/outer surface. 
     
     
         31 . A method of operating an element or an item according to  claim 26 , wherein air is fed to between the inner/first surface and the second/outer surface.
