Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
142 words
Air conditioning apparatus for an automotive vehicle comprising: an air conditioning unit; means for admitting air to said air conditioning unit; means associated with said air conditioning unit for conditioning air admitted to said air conditioning unit; air distribution means operatively connected to said air conditioning unit for receiving air therefrom and distributing the conditioned air, said air distribution meaNs including, a first elongated outer duct member, a second elongated inner duct member slidably disposed within said first elongated duct member; air discharge opening means in said air distribution means including means defining openings in each of said duct members which may be moved into register with each other to distribute conditioned air to selected locations; duct actuating means for moving one duct member longitudinally relative to the other; and selector means connected to said duct actuating means for actuating the latter.
Claim 2
Dependent Claim
142 words
Air conditioning apparatus for an automotive vehicle comprising: an air conditioning unit; means for admitting air to said air conditioning unit; means associated with said air conditioning unit for conditioning air admitted to said air conditioning unit; air distribution means operatively connected to said air conditioning unit for receiving air therefrom and distributing the conditioned air, said air distribution meaNs including, a first elongated outer duct member, a second elongated inner duct member slidably disposed within said first elongated duct member; air discharge opening means in said air distribution means including means defining openings in each of said duct members which may be moved into register with each other to distribute conditioned air to selected locations; duct actuating means for moving one duct member longitudinally relative to the other; and selector means connected to said duct actuating means for actuating the latter.
Claim 3
Dependent Claim
32 words
The combination of claim 1 including means connecting said duct actuating means to said inner duct member whereby the latter may be slidably moved longitudinally with respect to said outer duct means.
Claim 4
Dependent Claim
30 words
The combination of claim 1 wherein said air conditioning unit includes both a heating core and cooling core and separate conduit means from each leading to said air distribution means.
Claim 5
Dependent Claim
56 words
The combination of claim 1 wherein said outer duct member includes at least one air discharge opening adapted to be connected to a defrosting station, at least one air discharge opening adapted to be connected to a heating station, and at least one cold air discharge opening adapted to be connected to an air cooling station.
Claim 6
Dependent Claim
51 words
The combination of claim 4 including a cold air manifold operatively connected to said cold air discharge opening formed in said outer duct member, said cold air manifold being adapted to distribute cold air to a plurality of stations in the vehicle compartment with which said air conditioning apparatus is associated.
Claim 7
Dependent Claim
51 words
The combination of claim 1 wherein said outer and inner duct members each have formed in adjacent walls thereof at least one warm air discharge opening adapted to be brought into register with each other by actuation of said selector means to distribute warm air to at least one selected station.
Claim 8
Dependent Claim
73 words
The combination of claim 1 wherein said opening means include warm air discharge opening means formed in adjacent walls of said outer and inner duct members and adapted to be brought into register with each other by actuation of said selector mechanism; cold air discharge opening means formed in adjacent walls of outer and inner duct member and adapted to be brought into register with each other by actuation of said selector mechanism.
Claim 9
Dependent Claim
24 words
The combination of claim 7 including additional warm air discharge outlet formed in one end of each of said inner and outer duct members.
