Abstract: Disclosed herein is an air extractor grille. The air extractor grille includes a grille body and a grille cover. The grille body includes a plurality of openable flaps which are arranged vertically in a successive order in a vehicle body inside a rear bumper. The grille cover covers at least a portion of the grille body. The grille cover has a plurality of vent slots formed in a front surface of the grille cover and arranged vertically in a successive order as well. A block plate is bent from a lower end of each of the vent slots in such a way that the block plate protrudes outwards, thus preventing the vent slot from being directly exposed to the outside. Therefore, when the flaps open, foreign substances are prevented from directly entering the interior of the vehicle through the flaps.

Abstract: An air extraction apparatus for automotive vehicles opens an air flow path through the passenger compartment of the vehicle when wind throb conditions are sensed in the operation of the vehicle. The air extraction opening is located in a rear facing surface of the vehicle and is covered by a closure member that is movable by an actuator to selectively open the air extraction opening. The air extraction opening can be variable in cross-sectional area through the operation of the closure member to vary the rate of air flowing through the passenger compartment. The actuator is operatively coupled to a sensor that can sense wind throb conditions to affect an automatic opening of the air extraction opening. Wind throb conditions can be the existence of a single open window coupled with a minimum operating speed, or a threshold interior air pressure within the passenger compartment.

At least one control valve mounted on the valve mounting location allows air to flow from the vehicle interior to the atmospheric pressure when an air pressure in the vehicle interior exceeds a second predetermined pressure value that is greater than the atmospheric pressure and less than the first predetermined pressure value.

Abstract: An orientation-independent compartment pressure relief valve comprises a housing with a throughflow channel having an intake and an exhaust. A flange disposed around the inner wall of said housing defines an aperture within the throughflow channel and sealing flap is secured to the flange sealingly covering said aperture. Sealing flap is comprised of a relatively pliable layer and a relatively rigid layer and is oriented such that relatively pliable layer is in contact with flange. Pliable layer allows sealing flap to flexibly open in response to compartment pressure and rigid layer acts to close sealing flap irrespective of pressure relief valve's orientation in relation to a gravity vector.

Abstract: A ventilation system for a vehicle interior that reduces or eliminates smoke or polluted air from an interior of a vehicle by pulling air with fans through air intakes and expelling it outside vehicle. This invention is wired to a vehicle's electrical system and controlled by an on/off switch inside vehicle. Clean air inside a vehicle is beneficial in reducing health risks associated with breathing smoke or polluted air. The present invention also prevents deterioration of a vehicle's interior by reducing or eliminating smoke or polluted air that stains and causes odors to vehicle interiors.

Abstract: A ridge vent adapted specifically for use with tile roofs, and which does not require a nailer board to be installed on a roof prior to installing the ridge vent. The ridge vent includes a main body portion, a neck portion extending from the main body portion and a pair of flanges depending from the neck portion and extending away from one another. The flanges are adapted to be secured directly to a roof after the ridge vent is placed over an opening at the ridge of the roof. The neck portion includes a pair of accordion-like panels which permit the length of the neck portion to be increased or shortened to vary the spacing between the main body portion and the flanges. This enables the ridge vent to accommodate roof tiles having varying radaii of curvature. A plurality of living hinge portions permit the ridge vent to be unfolded into a relatively flat orientation to make same easier to package and ship.

Members 14-20 are pivotal along respective axes 78-84 which are each disposed at an angle 86 with respect to the longitudinal axis 60 of housing 12, and which allow assembly 10 to be operatively disposed in multiple positions and orientations.

Abstract: An air conditioning apparatus for a rear seat of a vehicle includes a centrifugal fan disposed at a downstream air side of an evaporator. The centrifugal fan is a backward curved fan having a plurality of blades each of which is curved backward relative to a rotation direction of the centrifugal fan. In the centrifugal fan, because a main component of velocity vector is in a radial direction of the centrifugal fan, a dynamical-pressure component of air blown from the centrifugal fan can be effectively changed to a hydrostatic-pressure component. Thus, during a cooler mode where air is simultaneously blown from first and second air outlets toward the rear space of the passenger compartment, a pressure of air blown from the first and second air outlets can be increased, and an amount of air blown toward the rear space of the passenger compartment can be sufficiently increased.

Abstract: Disclosed is a trunk ventilating device that operates to elevate or reduce the temperature of the vehicle trunk or trunk-like area. The device will accommodate a conventional rear deck of an automobile and provides a sealing aspect between the occupant area and the trunk area with the use of louvers that are made operational upon demand by the vehicle operator. The vehicle operator may initiate a dash mounted control switch that operates a high speed fan capable of drawing air from the occupants seating area into the otherwise sealed trunk area providing the proposed temperature elevation or reduction. Louvers are gravity or spring biased. It includes an aperture covering so as to prevent items from entering the trunk or engaging the rotating fan. A separate embodiment encompasses the use of a remotely located fan for areas lacking a definable trunk area for the purpose of transferring conditioned air from one part of the vehicle to another.

Abstract: A truck cab ventilation system and method is described which includes an air exhaust channel that extends from an upper channel portion adjacent the ceiling at the rear of the cab and through a lower channel portion to an exhaust vent mounted adjacent the floor of the cab over an exit opening in such floor. An inlet vent in the front of the cab produces a positive pressure within the cab which causes flow-through ventilation air flow from the front to the rear of the cab when the truck is moving. As a result, air flows into the upper channel portion of the exhaust channel and out of the exhaust vent through the exit opening to the exterior of the cab. The exhaust vent includes flexible louvers of elastomer which are held by gravity in a closed position and are moved into an open position when air flows out through the exhaust system.
