Abstract:
1. A blanket, comprising: an upper sheet and a lower sheet each having a periphery, the upper sheet and the lower sheet bonded together at their respective peripheries to form an inflatable structure consisting of the upper and lower sheets, the upper and lower sheets each being air impermeable; at least one air flow channel extending longitudinally along the structure away from a head portion of the structure, the air flow channel being defined by two sets of substantially in parallel non-contiguous strips that selectively bond the upper and lower sheets to each other at least a given distance longitudinally along the structure to form a non-inflatable section of the blanket, there being no other bonding of the upper and lower sheets between the two sets of substantially in parallel non-contiguous strips so that air flows uninterrupted through and is guided by the air flow channel along at least the given distance; wherein each set of the non-contiguous strips has at least two longitudinal strips of non-inflatable sections of the blanket in longitudinal alignment with each other, each of the longitudinal strips has a proximal end and a distal end, the respective proximal and distal ends of each of the strips of one of the two sets of non-contiguous strips being aligned with the respective proximal and distal ends of a corresponding strip for other of the two sets of non-contiguous strips to from at least one cross channel along the air flow channel to enable some of the air flowing through the air flow channel to escape to other sections of the structure; and a substantially rectangular area at a body portion of the structure formed by a substantially rectangular strip that bonds the upper sheet and the lower sheet together, the respective ends of the substantially rectangular strip being separated from each other so that the substantially rectangular area is not completely sealed off from the rest of the structure.
