A cooling device includes a duct, a passageway, and a plurality of nozzles spaced around the duct. The duct is sized to extend around at least a portion of the dome. The passageway may extend through the duct. The plurality of nozzles may be spaced around the duct and have first openings oriented toward the passageway and second openings oriented toward the surface.

A method for operating an air conditioning system, which may include a heating device, to condition air in a vehicle interior of a motor vehicle. At least one first air path and at least one second air path may each fluidically communicate with the air conditioning system and each open out into the vehicle interior. The method may include guiding the air from the vehicle interior via one of (i) the at least one first air path and (ii) the at least one second air path to the air conditioning system as a function of an operating state set in the air conditioning system. The method may also include guiding the air from the air conditioning system via the other of the one of (i) the at least one first air path and (ii) the at least one second air path into the vehicle interior.

A ventilation device for cooling a passenger compartment of a vehicle includes a blower module that is operationally coupled to an electrical circuit of a vehicle. A first duct assembly and a second duct assembly are coupled to the vehicle. The first duct assembly extends between a passenger compartment and at least one of a trunk and an opening in an exterior surface of the vehicle. The second duct assembly extends between the passenger compartment and an aperture in the exterior surface of the vehicle. At least one of the first duct assembly and the second duct assembly are operationally coupled to the blower module. The blower module is configured to exchange air in the passenger compartment with air from an ambient environment in which the vehicle is positioned to cool the passenger compartment.

A fastening module for connecting a filter system to an arched connecting surface with openings for a fluid has a connecting housing connectable in fluid communication to the filter system. Rigid individual channel pieces are arranged in the connecting housing and channels extend in the channel pieces. The channels correspond with the openings in the arched connecting surface. The channel pieces have connecting flanges to be connected to the openings in the arched connecting surface. The channel pieces are connected by flexible connecting regions with each other; with the connecting housing; or with each other and with the connecting housing. The fastening module is connected in fluid communication to the inlet region or outlet region of the filter system. A filter module for the filter system has substantially free intake across its cross section and enables an intake manifold-type distribution of a volume flow passing through the filter element.

A roof vent includes a roof disposed on a vehicle and a vent assembly. The vent assembly has at least one vent unit disposed on the roof and configured to enter the roof, a driving unit driving the vent unit, and at least one rack unit applying the driving force of the driving unit to the vent unit. The vent unit enters the roof due to operation of the driving unit.

A ventilation device for the inside of a motor vehicle, having at least one air outflow element and at least one associated directional element. The at least one air outflow element is provided in a functional arrangement with an air channel element. The air channel element represents the connection to a supply device as part of an air conditioning system. At least one light element is also provided. The arrangement of the at least one directional element and the at least one air outflow element work together so that the ventilation device can be continuously adjusted at least between two inside ventilation conditions. The at least two ventilation conditions respectively differ at least by means of a direction of outflowing air directed directly into the inside and directed indirectly along a roof liner designed for this reason in relation to a seat region of the motor vehicle.

Methods and apparatus are provided for active vehicle cabin occupant protection system. The method includes detecting a vehicle cabin temperature using a cabin thermal sensor, engaging a vehicle fan and opening a vehicle outside air ventilation duct in response to the vehicle cabin temperature exceeding a first threshold temperature, and starting a vehicle engine and engaging a vehicle air conditioning system in response to the vehicle cabin temperature exceeding a second threshold temperature wherein the second threshold temperature is greater than the first threshold temperature.

A roof vent includes a roof disposed on a vehicle and a vent assembly. The vent assembly has at least one vent unit disposed on the roof and configured to enter the roof, a driving unit driving the vent unit, and at least one rack unit applying the driving force of the driving unit to the vent unit. The vent unit enters the roof due to operation of the driving unit.

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.

A work vehicle includes a cabin to cover an operator's seat on a traveling body. A cabin frame that constitutes a framework of the cabin includes a pair of left and right front pillars, a pair of left and right rear pillars, a front beam, a rear beam, and side beams. The front beam couples upper end portions of the front pillars to each other. The rear beam couples upper end portions of the rear pillars to each other. Each of the side beams couples to each other upper end portions of each of the front pillars and each of the rear pillars that stand at a front and rear. The rear beam is formed to have a U-shaped cross-section by presswork of a metal plate material.
