Abstract
Abstract A ventilation or aeration device comprising an air vent for warm and/or fresh air. When used in a vehicle the device may serve as a window defogger by blowing warm air as well as a ventilator. In normal operation the vent may be manually manipulated as desired. When used as a defogger, opening of the warm air passage automatically directs the vent towards the window to be defogged or defrosted.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
182 words
An air ventilation device comprising: a feed for introducing warm air; a feed for introducing fresh air; movable air distribution means for distributing the air coming from said feeds in a direction which depends from the position of said movable air distribution means; first means comprising dampers for controlling said feeds to said air distribution means; and transmission means for connecting said first means to said air distribution means such that when said first means is in a first position corresponding to the introduction of warm air, the air distribution means is locked into a single position and cannot be displaced significantly, and when said first means is in a position different from the first, corresponding to the introduction of fresh air, said air distribution means is free to move in at least one direction and is adapted to be hand controlled, said transmission means comprising a flexible cord, one end of said cord being operatively connected to said damper which controls warm air flow, the other end of said cord being attached to said air distribution means at an attachment point.
Claim 2
Dependent Claim
182 words
An air ventilation device comprising: a feed for introducing warm air; a feed for introducing fresh air; movable air distribution means for distributing the air coming from said feeds in a direction which depends from the position of said movable air distribution means; first means comprising dampers for controlling said feeds to said air distribution means; and transmission means for connecting said first means to said air distribution means such that when said first means is in a first position corresponding to the introduction of warm air, the air distribution means is locked into a single position and cannot be displaced significantly, and when said first means is in a position different from the first, corresponding to the introduction of fresh air, said air distribution means is free to move in at least one direction and is adapted to be hand controlled, said transmission means comprising a flexible cord, one end of said cord being operatively connected to said damper which controls warm air flow, the other end of said cord being attached to said air distribution means at an attachment point.
Claim 3
Dependent Claim
27 words

Claim 5
Dependent Claim
157 words
A vehicle comprising a passenger compartment and at least one window, said vehicle further comprising a feed for introducing warm air; a feed for introducing fresh air; movable air distribution means for distributing the air coming from said feeds in a direction which depends from the position of said movable air distribution means; first means for controlling said feeds to said air distribution means; and transmission means for connecting said first means to said air distribution means such that when said first means is in a first position corresponding to the introduction of warm air, said air distrubtion means is locked into a single position whereby it is directed toward at least one window of said vehicle, and when said first means is in a position different from the first, corresponding to the introduction of fresh air, said air distribution means is free to move in at least one direction and is adapted to be hand controlled.
Claim 6
Dependent Claim
157 words
A vehicle comprising a passenger compartment and at least one window, said vehicle further comprising a feed for introducing warm air; a feed for introducing fresh air; movable air distribution means for distributing the air coming from said feeds in a direction which depends from the position of said movable air distribution means; first means for controlling said feeds to said air distribution means; and transmission means for connecting said first means to said air distribution means such that when said first means is in a first position corresponding to the introduction of warm air, said air distrubtion means is locked into a single position whereby it is directed toward at least one window of said vehicle, and when said first means is in a position different from the first, corresponding to the introduction of fresh air, said air distribution means is free to move in at least one direction and is adapted to be hand controlled.
Claim 7
Dependent Claim
