A recreational fifth wheel travel trailer includes a frame, a wheel for supporting the frame on a ground surface, and a body supported by the frame. The body has a length defined between a front end and a rear end of the body. A roof is coupled to the body, and an interior space is defined in the body between a floor and the roof. The travel trailer includes a door for providing entry to the interior space, a step for gaining access to the floor of the interior space, and a storage compartment at least partially formed by the body. The storage compartment is located below the floor of the interior space. The floor is defined along a plane from the rear end of the body to a location near the front end thereof such that the interior space is accessible without traversing more than a single step.

The seat air conditioner is a seat air conditioner included in a seat including a seat back and a headrest that is height-adjustable and attached to an upper portion of the seat back and. The seat air conditioner includes: a blower provided inside the seat; a first blowing port and a second blowing port that are formed in the seat back for blowing out air blown from the blower from the seat back; and the headrest. The second blowing port is disposed below the first blowing port, and the first blowing port is opened and closed in conjunction with a height adjustment movement of the headrest.

The present invention relates to a ventilation system 24 for a land vehicle 10. The ventilation system 24 comprises an inlet duct 26 for allowing exterior air to enter a cabin of the vehicle. The inlet duct 26 has a source port 38 located at an exterior of the vehicle 10 and the inlet duct 26 also has an exhaust port 40 located within a cabin of the vehicle 10. The ventilation system 24 has an outlet duct 28 for allowing interior air to exit the cabin of the vehicle 10. The outlet duct 28 has a source port 44 located within the cabin of the vehicle 10 and the outlet duct 28 also has an exhaust port 46 located at an exterior of the vehicle. The ventilation system 24 has an air propulsion element to cause selectively an airflow between the cabin interior and the vehicle exterior; wherein the source port 38 of the inlet duct 26 and the exhaust port 46 of the outlet duct 28 are collocated in a zone of substantially equivalent dynamic pressure, in-use.

A method of mitigating temperature buildup in a passenger compartment of a vehicle is provided. The method includes the steps of: (a) monitoring a temperature differential between a temperature inside the passenger compartment and an ambient temperature of the passenger compartment; (b) generating power utilizing the temperature differential; and (c) actuating a passive mitigation accessory when the temperature differential is above a predetermined threshold. The method may include the additional steps of using the power generated utilizing the temperature differential to actuate said passive mitigation accessory and/or providing the power generated utilizing the temperature differential to said passive mitigation accessory via at least one standard wire harness of the vehicle.

An automobile accessory is configured to quickly convert a truck bed into an enclosed cargo compartment, passenger compartment, or camping compartment. The automobile accessory has a truck cabin joined to a truck bed and further comprising a truck cabin rear bulkhead. At least two pockets are arranged proximate a plurality of roller skids on the truck bed. A chassis is joined to a cargo, passenger, or camping compartment having a compartment forward bulkhead. A gasket is joined to the passenger compartment forward bulkhead. The chassis is detachably secured to the truck bed and further comprising at least two rollers. Rolling the at least two rollers into the at least two pockets and installing the gooseneck or fifth wheel adapter joins the chassis to a truck under-bed gooseneck/fifth wheel hitch and the passenger compartment forward bulkhead compresses the gasket creating a seal between the passenger compartment and the truck cabin.

A seat air conditioning device for a vehicle includes: an inflow space formation part that forms an inflow space; and a blower having a suction part in which an air suction port is defined to communicate with the inflow space, and a blower fan that draws air from the inflow space through the air suction port to send the air into a seat. The inflow space formation part has a space communication hole that causes the inflow space and a space of the vehicle interior to communicate with each other. An opening-and-closing door disposed in the inflow space formation space closes the space communication hole from an inner side of the inflow space formation part, and is moved for opening the space communication hole by an air pressure difference defined by subtracting an air pressure in the inflow space from an air pressure in the vehicle interior.

A recreational fifth wheel travel trailer includes a frame, a wheel for supporting the frame on a ground surface, and a body supported by the frame. The body has a length defined between a front end and a rear end of the body. A roof is coupled to the body, and an interior space is defined in the body between a floor and the roof. The travel trailer includes a door for providing entry to the interior space, a step for gaining access to the floor of the interior space, and a storage compartment at least partially formed by the body. The storage compartment is located below the floor of the interior space. The floor is defined along a plane from the rear end of the body to a location near the front end thereof such that the interior space is accessible without traversing more than a single step.

A vehicle mounted refrigeration device comprising an outer shell, an inner shell nested in the outer shell, one or more heat sink plates attached to the inner shell, one of an insulating material and a vacuum spacing the inner shell from the outer shell, a control unit, and a compressor mounted to a vibration isolator.

A vehicle cabin venting method includes cooling a vehicle battery charger by drawing outside air through a vehicle outside air vent door; and operating a hybrid vehicle battery system to establish and maintain flow of fresh air in a cabin of the vehicle by ensuring an open position of a blend door in the vehicle if the outside air vent door will not close. A vehicle cabin venting system is also disclosed.

An air venting system includes, among other things. A box of a truck. The box provides a cargo area. The system further includes a cab back panel of the truck. The cab back panel has an exposed section that provides a front wall of the cargo area. The cab back panel has a hidden section outside the cargo area. An air extractor is held within the hidden section of the cab back panel.
