Abstract: A system to clean windshields using pneumatic pressure including a blower assembly and a vent assembly is disclosed herein. The blower assembly comprises a plurality of self-contained blowers including an intake duct and an exhaust duct mounted within a vehicle. The self-contained blowers carry air through air ducts to the vent assembly mounted to the exterior of the vehicle. The air supplied from the plurality of self-contained blowers dry the windshields of water and debris without obscuring the vision of a driver within the vehicle. Additionally, the vent assembly includes a front windshield vent, a rear windshield vent and side window vents mounted onto the exterior of a vehicle. The system creates an invisible air curtain to act as a barrier to prevent any rain, snow, or debris of any type to come in contact with the windshields of a vehicle.

Abstract: A vehicle defroster includes an inlet for receiving an air flow, a wall dividing the air flow into a primary airflow and a secondary airflow, a primary duct guiding the primary airflow out a primary outlet onto a first portion of a windshield, and a secondary duct guiding the secondary airflow out a secondary outlet onto a second portion of the windshield. The defroster may include a primary chamber receiving the primary airflow and a secondary chamber receiving the secondary airflow. The primary chamber may be formed by a front section and a rear section. The wall may include a proportioning member, and the proportioning member may extend toward the primary chamber.

Abstract: A spoiler system for a vehicle includes a spoiler body having a spoiler surface for influencing an air flow around the vehicle; and a spoiler receptacle having a sealing device with a seal configured to provide sealing between the sealing device and a sealing surface of the spoiler body during an extension movement of the spoiler body from a retracted position into an extended position. The spoiler body is movably mounted on the spoiler receptacle between the retracted position in which the spoiler body is received at least partially in the spoiler receptacle and the extended position in which the spoiler body is extended at least partially out of the spoiler receptacle.

Abstract: A spoiler arrangement of a motor vehicle includes a spoiler blade, a body portion to which the spoiler blade attaches, a displacement device for the spoiler blade, the displacement device being configured to move the spoiler blade relative to the body portion between a retracted position and an extended position; and a cover configured to attach to the spoiler blade and to at least partially close a rear gap which is formed, in the extended position of the spoiler blade, between a rear edge of the spoiler blade and an adjoining assembly of the body portion.

Abstract: A variable-air-volume system for modulating the speed of a supply fan by measuring a plurality of inlet static pressures within the inlet of a corresponding plurality of terminal boxes within the system; calculating a plurality of setpoint errors equal to the difference between the plurality of inlet static pressures and a corresponding plurality of terminal box setpoint pressures; selecting minimum setpoint error out of all of the calculated setpoint errors; and modulating the fan speed as a function of the minimum setpoint error. The system can also utilize a power adjustment factor to modify the terminal box set point pressures.

Abstract: A vehicle heating system employs a vehicle rearview mirror outer case that defines a cavity within which a mirror resides. A vehicle rearview mirror inner case may define a cavity and the rearview mirror inner case may reside within the rearview mirror outer case. A mirror surface or mirror structure, such as glass or plastic, may reside against the rearview mirror inner case to enclose the inner case, with the exception of air inlet and outlet tubes. A rearview mirror inlet tube may pass through the outer case and the inner case and permit air to enter the rearview mirror inner case. A rearview mirror outlet tube that passes through the outer case and the inner case may permit air to exit the rearview mirror inner case. An HVAC unit attaches to the rearview mirror inlet tube to blow air into the rearview mirror outer case or inner case.

Abstract: This is a windshield-blowing device, which can retract through an existing device placed on the hood of the vehicle. It will direct air from an air supply towards a series of tubes, which telescope, and eventually through a series of holes in a manifold that can pivot or swivel.

Abstract: An air flow device for generating an air flow 30 across a windshield 4 of a vehicle 2, the air flow device has one or more means 10 for generating an air flow 32 located in proximity on a lateral end or side of the windshield 4, the one or more means 10 for generating an air flow 30 directs the flow of air laterally onto the windshield 4. The one or more means 10 for generating an air flow 30 has one or more fans 20 rotatable about an axis 22. Each fan 20 has a plurality of fan blades 24 for intaking air near the axis of rotation 22 of the fan blade 24, the fan blades 24 extend longitudinally having a cross section of increasing curvature to a substantially flattened unshaped terminal end 24E for directing the air flow 30 laterally. The one or more fans 20 can be driven by a single motor 25. Alternatively, each fan 20 may include a motor 25 for driving the fan blade 24.

Abstract: A system including a defrosting mechanism in the form of an air stream directed against the side view mirror of a vehicle as well as an air stream directed against the side window of the vehicle adjacent to the side view mirror. The side view mirror and side window defogger system for vehicles also includes one or more adjustment mechanisms to allow the user to optimize the defogging air streams directed toward the side view mirror and the side window.

Abstract: A water droplet removing system for a vehicle provided with door mirror assemblies each having a door mirror base attached to a door body, and a mirror unit guides air discharged by a blower installed in a door body of the automobile to at least either the surface of a mirror included in the mirror unit or the outer surface of a side window to blow off water droplets wetting the surface of the mirror or the outer surface of the side window. The blower is installed in a dead space defined in front of a guide rail placed in the door body to guide the front edge of the side window for vertical movement in the door body so that the interference between the blower and parts arranged within the door body including the side window can be avoided.

Abstract: A defroster assembly uses heat from an engine's exhaust to heat the exterior of a windshield and the wipers thereon. The assembly comprises an air intake mechanism shared with the engine's air filter. The air intake mechanism leads to air ducts spaced from the engine block. Nodes in the air ducts encircle exhaust outlet pipes leading from the engine so that heat of the engine exhaust is transferred to air in the ducts. The assembly includes a vent subassembly for directing a stream of air in a laminar flow along the windshield. A fan of the assembly draws air from the ducts and forces it through the vent subassembly.

Abstract: Disclosed is a device to remove moisture from a side view mirror and adjacent side window of a vehicle. The device increases mirror clarity and can be installed on a side view mirror housing at the factory or as an after factory installation. The device prevents moisture from interfering with the operator's visual use of the mirror by utilizing the cleansing effects of existing air flow about the mirror housing during vehicle movement when it redirects the air flow past the mirror surface. The device also uses the air flow to prevent the build up of moisture on the adjacent side window of the vehicle. The device can be adapted to accommodate any existing vehicle mirror design that is incorporated into the door frame or in close proximity. The device is a semi-rigid mirror attachment that mounts on the mirror housing without obstructing the operator's field of vision.

Abstract: In a preferred embodiment, an exterior windshield surface blower system to direct a flow of air at the windshield of a vehicle to remove rain and snow therefrom, the system including: an air deflector disposed along a lower edge of the exterior windshield surface and having a generally vertical face in proximity thereto, an air directing jets disposed in the face so as to direct forced air against the windshield, and an air supply arrangement to supply air to the air directing jets.
