A ventilation system is provided for a transportation vehicle having a passenger cabin with an interior trim surface. A stationary duct segment receives an inlet air flow and has a stationary outlet hidden behind the interior trim surface. A telescoping duct segment has a sliding inlet sealingly coupled to the stationary outlet so that it slides on the stationary outlet between a retracted position and an extended position. The telescoping duct segment has a movable outlet arranged to provide a variable flow cross section to the passenger cabin that increases as the telescoping duct segment slides from the retracted position to the extended position. A trim hood provides a portion of the interior trim surface and is movable with the telescoping duct segment. The trim hood has a pivot axis at an end of the trim hood remote from the movable outlet.

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 heating, ventilation and/or air-conditioning apparatus (1) for the passenger compartment of a motor vehicle includes a housing (2) comprising a first air inlet (3) and a second air inlet (4). The housing (2) directs an inner air flow (Fi) from the first air inlet (3) and/or the second air inlet (4) and contains at least a first heat exchanger (5). The housing (2) includes: an air flow channel (24) directing the inner air flow (Fi) in the housing (2) while bypassing the first heat exchanger (5); and an air inlet duct (23) directing the inner air flow (Fi) in the housing (2) through the first heat exchanger (5). A heating, ventilation and/or air-conditioning installation for the passenger compartment of a motor vehicle includes: an air conditioning loop through which a coolant flows. The loop includes at least one compressor, a first expansion member, an outer heat exchanger and the first heat exchanger (5). The installation also includes the heating, ventilation and/or air-conditioning apparatus (1).

An operator station (100) for a work vehicle comprises a roof, a roof (102), that defines an outside air inlet (201); a floor (115); several windows (106) extending between the floor (115) and the roof (102) that together define in enclosed operator compartment; an operator seat (108) disposed within the operator compartment; an air-conditioning module (112) disposed adjacent to the floor (115); a first air conduit extending between an outside air inlet (201) and the air-conditioning module (112); and a second air conduit extending between the air-conditioning module (112) and a first conditioned air outlet of the roof (102).

A windshield sunshade with solar powered fans including a foldable, pleated opaque panel including a plurality of panel section with at least two panel sections having a solar powered fan motor-blade unit centrally disposed in a recessed portion thereof. A shaft of each fan-motor blade unit is detachable from at least one of a yoke and a motor thereof to permit a casing along with vanes attached thereto to be detached from the respective panel section to fold the panel. Each fan motor-blade unit includes at least one solar module fixedly disposed on the outer side of the respective panel section power the motor. An on-off switch proximal each fan motor-blade unit in a position proximal the vehicle dashboard is provided. A protective front grill is disposed solely over the entire one of each recessed portion to protect against contact with the vanes of the fan motor-blade unit.

The present invention relates to a flap (14) for an air extractor (10), in particular of a motor vehicle, said flap comprising a rigid or semi-rigid wall (42) and articulation means (40) to allow a pivoting of the flap about an axis (A) substantially parallel to the wall, wherein the articulation means are located on a single edge (44) of the wall. The articulation means are spaced from said wall and comprise a swivel element (40). The swivel elements are preferably spherical or rod shaped. It also relates to an air extractor (10), in particular of a motor vehicle, comprising a support (12) having at least one window defining an opening for the passage of air and at least one flap (14) as described above and movable between a position of closure of the opening and a position of opening up this opening.

A motor vehicle is provided in which cold air is prevented from flowing forwards from the rear region to the front seats when travelling with an open top. At least one air outlet opening or air outlet nozzle is formed at a rear end of the center console, through which air outlet opening or air outlet nozzle warm air can flow out upwards and/or forwards between the two backrests of the two front seats. Further air outlet openings are provided in the two opposite B body pillars, through which air outlet openings warm air can flow out forwards in the direction of the backrests of the front seats and/or in the transverse direction of the vehicle into the rear region.

A pressure relief valve is provided that includes a housing and a flap. The housing includes a plurality of receptacle members with openings therebetween, and the flap is configured to be accepted by the housing and to contact the receptacle members in a closed position. Further, the flap covers the openings and inhibits airflow through the openings in a closed position, and the flap is biasable to allow airflow through the openings in an open position.

Embodiments of the present invention are directed to a method and system for preventing ingestion of ambient air contaminated with possibly harmful, toxic, or flammable battery gases into a passenger compartment of a vehicle in the event of a battery failure. If an abnormal state is detected in a battery pack of the vehicle, the vehicle automatically switches the HVAC system to air recirculation mode, thereby preventing any toxic gas emitted from the battery pack from entering the passenger compartment.
