A drain valve (10), such as for a vehicle body structure, having: at least one frame (12); and at least one flap (14) secured to the at least one frame (12); at least one drain opening (13); wherein the at least one drain valve (10) is located within the at least one drain opening (13); wherein the at least one drain valve (10) has at least two positions: a sealed position, in which the at least one flap (14) prevents airflow; and an open position, in which the at least one flap (14) allows liquid to flow through the at least one drain valve (10).

A pressure relief assembly includes a housing that comprises an air passage chamber and a membrane flap positioned within the air passage chamber. The pressure relief assembly further includes a plurality of clips that extend upwardly from the housing. The plurality of clips anchor the membrane flap to the housing. Further, the plurality of clips are staggered.

An air extractor for a vehicle, the air extractor comprising a frame having a top portion, a bottom portion, a left side portion and a right side portion surrounding a central air passage, the frame having an inlet side for receiving air from a passenger compartment of the vehicle and having an outlet side for exhausting the air from the passenger compartment of the vehicle, a gasket to seal the frame to the vehicle, a plurality of spoilers supported by the frame and disposed within the central air passage and a plurality of flaps pivotally mounted on the outlet side to pivot between a closed position that inhibits airflow and an open position that permits airflow, wherein each of the flaps comprises a plurality of bumpers to attenuate slap noise of the flaps and wherein each of the flaps further comprises a skirt to minimize air leakage.

A pressure relief valve includes a housing including an air passage chamber defining an airflow passage and a membrane flap secured within the air passage chamber. The membrane flap covers the airflow passage in a closed position. A portion of the membrane flap is configured to move off the airflow passage into an open position. A flap motion dampener is proximate to the airflow passage. The flap motion dampener is configured to control motion of the membrane flap as the membrane flap seats over the airflow passage in order to dampen noise.

A waste exhaust ventilation door automatic control device comprises a core body (8), an inner door body (2) and an outer door body (1); wherein the core body is fixed on a ventilation opening of the waste exhaust ventilation door, a top of the outer door body is movably hinged on an outer side of the core body, and a bottom of the inner door body is movably hinged on an inner side of the core body; when there is no pressure fluctuation outside the core body, the outer door body and inner door body will open, and when there is pressure fluctuation outside the core body, the outer door body and/or the inner door body will be closed automatically due to a pressure difference between inside and outside the core body. A vehicle body comprising the waste exhaust ventilation door automatic control device is also provided.

A vehicle includes a vehicle body including a quarter panel assembly. The quarter panel assembly includes an inner quarter panel and an outer quarter panel located outboard of the inner quarter panel forming a volume therebetween. The outer quarter panel has a vent opening extending therethrough. A quarter vent assembly is connected to the outer quarter panel covering the vent opening. An exterior fascia covers the quarter vent assembly such that an air gap is provided between the quarter vent assembly and the exterior fascia. A service hole cover is located in the volume between the inner quarter panel and the outer quarter panel. The service hole cover includes a cover body and a noise reduction flange at a bottom of the cover body that extends inboard toward the inner quarter panel at the vent opening.

A vehicle includes an openable door, a discharge port, a valve and a rotation mechanism. The discharge port communicates a vehicle cabin space with an outside, and discharges air in a vehicle cabin to the outside. The valve is rotatable between an open position for opening the discharge port and a closed position for closing the discharge port. The rotating mechanism couples the door with the valve such that the valve is rotated from the closed position to the open position when the door is opening, and rotated from the open position to the closed position when the door is closing. The rotating mechanism does not bring the valve being rotated from the open position to reach the closed position at a moment when the door is closed, and further rotates the valve to the closed position when the door is in a state of being closed.

The invention relates to a method for producing a body component (1) for a motor vehicle (2), said body component (1) being made of a main body (3), formed from a batt that is embedded in a plastics matrix, and comprising at least one air-removal device (4), in particular for removing air from an interior (5) of the motor vehicle (2). The air-removal device (4) comprises at least one ventilation opening (7) that can be reversibly sealed by means of at least one ventilation flap element (6).

A plastic glazing of a tailgate of a vehicle is provided, the plastic glazing comprising: a first translucent component comprising a full panel of the plastic glazing; a second translucent component molded onto the first translucent component, wherein the second translucent component is a colored thermoplastic polymer, wherein the plastic glazing is of one-piece molded plastic construction, wherein at least one of the first translucent component and the second translucent component comprises one or more aerodynamic features, wherein the one or more aerodynamic features are each configured to reduce one or more of: a turbulence, a drag force, and a lift force.

A pressure relief assembly (100) is configured to be secured to a portion of a vehicle. The pressure relief assembly (100) includes a pressure relief device (102) and a liquid-diverting cover (104) including at least one liquid diversion vane (150) that defines at least one air outlet (152). The liquid diversion vane(s) (150) is configured to block liquid from passing into an interior cabin of the vehicle. The air outlet(s) (152) allows airflow from within the vehicle to pass out of the interior cabin of the vehicle.
