Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
153 words
A ventilation system for vehicles with a forced air supply conducted into the vehicle interior by way of line means comprising an outer impervious member of the vehicle, at least one interior panel member spaced from the outer impervious member of the vehicle, means for spacing the interior panel member from tHe outer impervious member, the panel member forming one of an interior wall and door panel, a discharge of the line means being arranged behind a portion of the interior panel member, the panel member including a closed wall with an opening for the discharge of the line means, a porous intermediate layer secured at the wall and having substantially the same porosity in all directions throughout the layer for distributing supplied air in all directions within the layer, and a porous cover means covering the intermediate layer for discharging air passing through the intermediate layer into the interior of the vehicle.
Claim 2
Dependent Claim
153 words

Claim 3
Dependent Claim
153 words
A ventilation system for vehicles with a forced air supply conducted into the vehicle interior by way of line means comprising an outer impervious member of the vehicle, at least one interior panel member spaced from the outer impervious member of the vehicle, means for spacing the interior panel member from tHe outer impervious member, the panel member forming one of an interior wall and door panel, a discharge of the line means being arranged behind a portion of the interior panel member, the panel member including a closed wall with an opening for the discharge of the line means, a porous intermediate layer secured at the wall and having substantially the same porosity in all directions throughout the layer for distributing supplied air in all directions within the layer, and a porous cover means covering the intermediate layer for discharging air passing through the intermediate layer into the interior of the vehicle.
Claim 4
Dependent Claim
153 words
