A vehicle passenger compartment vent structure that includes a rear wall structure, a drafter vent assembly, a baffle and a trim panel. The rear wall structure defines a rearward area of a passenger compartment of a vehicle. The rear wall structure defines at least one vent opening. The drafter vent assembly is installed to the rear wall structure covering the at least one vent opening. The baffle is installed to the rear wall structure adjacent to the drafter vent assembly and is configured to dampen sound from the drafter vent assembly. The trim panel is installed to the rear wall structure contacting the baffle and concealing the drafter vent assembly.

A cover (1) for a pressure-limiting valve arrangement of a vehicle, wherein the cover (1) has at least one side wall (2a, 2b, 2c), preferably at least two side walls, and has a wall region (3) serving as a lid region of the cover (1), wherein the cover (1) is transferable from a state of manufacture into a state of use, wherein, in the state of manufacture, the at least one side wall (2a, 2b, 2c) and the wall region (3) serving as a lid region are situated at least substantially and/or at least regionally in a common plane, and wherein, in the state of use, the at least one side wall (2a, 2b, 2c) and the wall region (3) serving as a lid region are situated in mutually different planes.

A vehicle air purging system includes a vehicle body that defines an interior. A support member is coupled to the vehicle body. The support member defines a receiving cavity. The support member defines an aperture proximate the receiving cavity. A one-way valve is coupled to the support member and is disposed within the aperture. A fan is coupled to the support member. The fan includes an outlet aligned with the aperture. A controller is operably coupled to the fan. The controller is configured to activate the fan to blow air from the interior to an area external to the vehicle body through the one-way valve.

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 ventilation valve for a vehicle for letting air out of a vehicle interior includes a valve frame with at least one through opening, and at least one valve flap which is mounted on the valve frame and is adjustable between a closed position and an open position. The at least one valve flap closes the at least one through opening in the closed position and opens up the at least one through opening in the open position. Air escaping through the at least one through opening flows from an air inlet side to an air outlet side along a main flow direction. A wall bounding the at least one through opening is inclined into the air flow in such a manner that the through opening tapers in the main flow direction.

A cab for a work vehicle includes: walls enclosing a cab environment; a door coupled to one of the walls, one of the walls or the door comprising a vent opening; a heating, ventilation, and air conditioning (HVAC) system coupled to the cab environment and configured to regulate a temperature and a pressure of the cab environment; and a pressure control flap associated with the vent opening and comprising a pressure-relief opening and a magnetic portion that is configured to hold the flap closed when the pressure of the cab environment is below a threshold pressure and allow the pressure to open the flap when the pressure exceeds the threshold pressure.

A rear wall structure of a passenger compartment includes a vent opening and a horizontally extending seal protruding in a vehicle forward direction. A trim panel has a rear surface facing the rear wall structure. A vertically extending seal extends from the rear surface. With the trim panel installed to the rear wall structure the vertically extending seal contacts the rear wall structure, and, the horizontally extending seal of the rear wall structure contacts the rear surface of the trim panel such that the rear surface and the vertically extending seal of the trim panel and the upright interior surface and the horizontally extending seal of the rear wall structure define an air outlet passageway that extends from an opening in the trim panel to the vent opening.

An air extractor assembly includes, among other things, a housing, a first valve, and a second valve. The first valve is coupled to the housing and configured to transition from a sealed position to a pressure releasing position in response to a first pressure differential. The second valve is coupled to the housing and configured to transition between a sealed position and a pressure releasing position in response to a second pressure differential that is different than the first pressure differential.

A pressure relief assembly includes a housing defining an air passage chamber having at least one opening, and a membrane flap secured within the air passage chamber. The membrane flap is configured to move into an open position to expose the opening(s) to relieve air pressure. A plurality of flap-retaining clips securely couple the membrane flap to the housing. Each of the plurality of the flap-retaining clips includes a main body. A housing-connecting tab extends from a first end of the main body. The housing-connecting tab is retained within a retaining channel formed in the housing. Opposed flap-retention wings laterally extend from opposite sides of the main body. A portion of the membrane flap is trapped between the opposed flap-retention wings and the housing to securely couple the membrane flap to the housing.

A roof vent includes a roof disposed on a vehicle and a vent assembly. The vent assembly includes at least one vent unit disposed on the roof and configured to be popped up to the interior of the vehicle, a driving unit driving the vent unit, and at least one rack unit applying driving force of the driving unit to the vent unit. The vent unit is popped up or tilted by the driving unit.
