Environmentally controlled sleeping zone and thermal barrier

An environmentally controlled sleeping area comprising a thermal barrier projecting above a bed and at least partially enclosing each of all four sides of the bed and an environmental control unit providing thermally conditioned air between said four sides, the thermally conditioned air being trapped on top of the bed by the thermal barrier, wherein the environmentally controlled sleeping area is contained in the bunk area of a vehicle, wherein the outer walls of the bunk area enclose three sides of the bed, further comprising a partial wall extending only partially above the top surface short of a ceiling of the bunk area enclosing the remaining side of the bed, and wherein the partial wall is removable to allow entry and exit to and from the bed.

An environmentally controlled sleeper area in a bunk area of a vehicle, the bunk area is adjacent to a cab area of the vehicle, the bunk area having an end wall and a pair of side walls extending generally perpendicular to the end wall, the side walls and the end wall encompassing three sides of a bed, thereby leaving an open side of the bed whereby a person can maneuver in and out of the bed, further comprising:

• a thermal barrier along the remaining open side of the bed, the thermal barrier adapted to rise above the top surface of the bed and thermally separate the sleeping area from a remainder of the bunk area;
• and
• an environmental control unit having a discharge outlet above the bed arranged to discharge thermally conditioned air over the bed, wherein the thermal barrier traps thermally conditioned air along the top of the bed between the back wall and thermal barrier.
