Abstract: A device for ventilating and cooling the interior of a vehicle with at least one air guide channel (7) having air inlet openings (8) located in the rear of a solar cell equipped vehicle roof (5a, 5b), the air guide channel (7) being restricted to the rear area (3) of the vehicle roof (5a, 5b) and having at least one fan (15) for taking in outside air (10) and at least one cooling element (14) for cooling the air taken in. The bottom of the air guide channel (7) is formed by a first section (12) of a roof portion (5b) which extends from the vehicle rear toward the vehicle front (3, 1) and the top of the air guide channel (7) is formed by a second section (13) of a roof portion (5a) which extends from the vehicle front toward the vehicle rear (1, 3).

Abstract: The invention relates to a roof module of a motor vehicle, which can be fastened to the chassis of the motor vehicle and defines a roof area. The aim of the invention is to improve the utility of the roof module or the motor vehicle. For this purpose, the roof module (9) is a planar full roof that is non-transparent or at least partially transparent, or the roof module (9) is a panoramic roof that projects towards the top and/or is at least partially transparent and/or comprises a roof box fixed to the top thereof, or comprises a bearing device (18) for detachably fixing a roof box (19) to the top of the roof module (9).

Abstract: The invention relates to a mortor vehicle comprising an air-conditioning unit (10) that is provided with an electrically operated compressor (12). Said motor vehicle further comprises a generator (16) which can be operated by a vehicle drive unit (14) in order to generate electric power, a battery (18) that can be charged by means of the electric power generated by the generator, and a solar module (22) for generating electric power, the motor vehicle especially being a hybrid vehicle. According to the invention, another battery is provided which can be charged using the power generated by the solar module (22) while the electrically operated compressor (12) can be operated using power stored in the first battery (18) and/or power stored in the additional battery (20).
