Abstract
Abstract A motor vehicle body which includes a windshield and a body structure located in front thereof, especially for passenger motor vehicles, in which the windshield and/or other parts of the vehicle are kept substantially free of dust and dirt by providing apertures in the body structure in front of the windshield through which either at least a part of the dynamic air flow, which would normally flow against the windshield and/or other part to be kept clean, is sucked off into and through the vehicle body or an additional air stream or air flow is blown directly toward the windshield and/or other vehicle wall to be kept clean.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
130 words
In a motor vehicle body including a body wall, a windshield and a body structure disposed in front thereof, the improvement comprising means for directing an air flow past at least one of the body wall and the windshield of the motor vehicle to provide effective protection therefor against soiling by road dirt and dust, including an opening located directly in front of said at least one of the windshield and the body wall to be protected in said body structure and deflection means, providing a flow of air directed upwardly and forwardly at an angle of approximately 30* with respect to the vertical, for deflecting the air stream normally directed at the windshield when the motor vehicle is in forward motion, so that said air stream is deflected upwardly.
Claim 2
Dependent Claim
130 words
In a motor vehicle body including a body wall, a windshield and a body structure disposed in front thereof, the improvement comprising means for directing an air flow past at least one of the body wall and the windshield of the motor vehicle to provide effective protection therefor against soiling by road dirt and dust, including an opening located directly in front of said at least one of the windshield and the body wall to be protected in said body structure and deflection means, providing a flow of air directed upwardly and forwardly at an angle of approximately 30* with respect to the vertical, for deflecting the air stream normally directed at the windshield when the motor vehicle is in forward motion, so that said air stream is deflected upwardly.
Claim 3
Dependent Claim
40 words
A motor vehicle body according to claim 1, further including channel means in communication with said deflection means for conducting a stream of air to said deflection means, said stream of air being the source of said flow of air.
Claim 4
Dependent Claim
43 words
A motor vehicle body according to claim 2, further including inlet means disposed within a portion of the body for creating a positive air pressure during the forward motion of the vehicle, whereby said stream of air is conducted through said channel means.
Claim 5
Dependent Claim
41 words
A motor vehicle body according to claim 3, wherein said channel means communicates with said deflection means through a blower, whereby said stream of air is conducted at a high velocity to said deflection means by the action of said blower.
Claim 6
Dependent Claim
17 words
A motor vehicle body according to claim 3, further including a heat-exchanger located within said channel means.
Claim 7
Dependent Claim
41 words
A motor vehicle body according to claim 2, wherein said channel means communicates with said deflection means through a blower, whereby said stream of air is conducted at a high velocity to said deflection means by the action of said blower.
Claim 8
Dependent Claim
26 words
A motor vehicle body according to claim 2, further including air-guide means in communication with said channel means for venting and heating the vehicle interior space.
Claim 9
Dependent Claim
39 words
A motor vehicle body according to claim 7, wherein said air-guide means communicates with said channel means through a selectively operable closure means for selectively adjusting the amount of air passage between said channel means and said air-guide means.
Claim 10
Dependent Claim
17 words
A motor vehicle body according to claim 8, further including a heat-exchanger located within said channel means.
Claim 11
Dependent Claim
41 words
A motor vehicle body according to claim 9, wherein said chaNnel means communicates with said deflection means through a blower, wherein said stream of air is conducted at a high velocity to said deflection means by the action of said blower.
Claim 12
Dependent Claim
43 words
A motor vehicle body according to claim 8, further including inlet means disposed within a portion of the body for creating a positive air pressure during the forward motion of the vehicle, whereby said stream of air is conducted through said channel means.
Claim 13
Dependent Claim
17 words
A motor vehicle body according to claim 2, further including a heat-exchanger located within said channel means.
Claim 14
Dependent Claim
13 words
A motor vehicle body according to claim 1, wherein said opening is slotted.
Claim 15
Dependent Claim
15 words
A motor vehicle body according to claim 1, wherein said opening is provided with nozzles.
