A segmented cushion cover apparatus for a cushion such as a vehicle seat or a mattress for connection with a supply of pressurized temperature-and-humidity-modified air flowing from an air vent to supply conditioned air to a person resting on said cushion, said cover apparatus comprising: (a) a vent attachment assembly including: (1) an air chamber having a first opening framed by a flange means; (2) sealing means for sealably attaching said flange means to the perimeter of said air vent in air-tight relationship; (3) a second opening in said air chamber opposed to said first opening and arranged to provide an air outlet functioning as a substitute for said air vent, said second opening provided with a first valve means for controlling the flow of air therethrough; (4) a third opening in said air chamber provided with duct attaching means for connecting an air duct and a second valve means for controlling the flow of air therethrough; (b) a segmented cushion cover having at least two segments, said segments hingedly connected together along one edge and each segment comprising: (1) a broad air-impervious rear panel; (2) a broad air-pervious front panel; (3) air-impervious narrow sides joining said rear and front panels together to define a broad, thin internal space having a thickness greater than one-sixteenth inch and pervious to air through a broad front face; (4) air-pervious spacing means contained within said internal space, said spacing means for holding said front panel spaced apart from said rear panel against the closing forces of the body resting on said cushion; (5) duct connecting means for operatively connecting said internal space to an air duct; and (c) air duct means for connecting said duct attaching means of said said vent attachment assembly to said duct connecting means of each segment.

A segmented cushion cover apparatus for a cushion such as a vehicle seat or a mattress for connection with a supply of pressurized temperature-and-humidity-modified air flowing from an air vent to supply conditioned air to a person resting on said cushion, said cover apparatus comprising: (a) a vent attachment assembly including: (1) an air chamber having a first opening framed by a flange means; (2) sealing means for sealably attaching said flange means to the perimeter of said air vent in air-tight relationship; (3) a second opening in said air chamber opposed to said first opening and arranged to provide an air outlet functioning as a substitute for said air vent, said second opening provided with a first valve means for controlling the flow of air therethrough; (4) a third opening in said air chamber provided with duct attaching means for connecting an air duct and a second valve means for controlling the flow of air therethrough; (b) a segmented cushion cover having at least two segments, said segments hingedly connected together along one edge and each segment comprising: (1) a broad air-impervious rear panel; (2) a broad air-pervious front panel; (3) air-impervious narrow sides joining said rear and front panels together to define a broad, thin internal space having a thickness greater than one-sixteenth inch and pervious to air through a broad front face; (4) air-pervious spacing means contained within said internal space, said spacing means for holding said front panel spaced apart from said rear panel against the closing forces of the body resting on said cushion; (5) duct connecting means for operatively connecting said internal space to an air duct; and (c) air duct means for connecting said duct attaching means of said said vent attachment assembly to said duct connecting means of each segment.
Claim 3
Dependent Claim
27 words
The cushion cover assembly according to claim 1 including individual valve means operatively connected to each segment for selectively controlling the flow of air to each segment.
Claim 4
Dependent Claim
36 words
The cushion cover assembly according to claim 1 including air-impervious flap means arranged to be removably applied to portions of said front panel to selectively block the flow of air through areas of said front panel.
Claim 5
Dependent Claim
26 words
The cushion cover assembly according to claim 1 in which said spacing means includes projections connected to said rear panel and extending into said internal space.
Claim 6
Dependent Claim
24 words
The cushion cover assembly according to claim 4 in which said rear panel is a thin sheet that is formed to provide said projections.
Claim 7
Dependent Claim
17 words
The cushion cover assembly according to claim 4 in which said spacing means includes resilient wire coils.
Claim 8
Dependent Claim
17 words
The cushion cover assembly according to claim 1 in which said spacing means includes resilient wire coils.
Claim 9
Dependent Claim
50 words
The cushion cover assembly according to claim 1 in which said front panel is constructed with reduced air permeability in that area close to said duct connecting means and increased air permeability in those areas remote from said connecting means to equalize the flow of air through said front panel.
Claim 10
Dependent Claim
25 words
The cushion cover assembly according to claim 8 in which variable permeability of said front cover is provided by a fabric woven with variable density.
Claim 11
Dependent Claim
26 words
