1 110315 Vehicle heating system

The invention relates to a heating arrangement for a vehicle comprising an electrically powered auxiliary resistance system 5 for indirectly heating the vehicle driver and / or passenger by raising the surface temperature of the interior of the vehicle adjacent to the vehicle seat, comprising at least one

For the above purpose, it is known today to use a bench warmer which heats one or more seats of a vehicle by direct heat conduction. Such electric seat heaters, embedded in the seat upholstery, are often included in the original equipment of the vehicle, but can also be purchased either inside or outside the seat trim as retrofit accessories. This type of bench warmer has a particularly important role in improving comfort in the Nordic environment and, in certain occupations, also has a greater likelihood of preventing work-related illnesses to some extent. Conventional bench heaters usually • operate by being switched on by a separate operating switch, after which it automatically switches off when the bench temperature rises above a certain, ·,: limit temperature.

Seat heaters of the type described above do not:, · Firstly, do not sufficiently improve the working / operating comfort especially for professional use, · '; vehicles, and not in all cases 35 ordinary passenger cars. Particularly in a van or, for example, a lower-priced passenger car, it is common to feel a strong sense of traction when driving, very often due to the cold-shining side doors of the 110315 2 or its roof or rear surfaces. In addition, if the vehicle's actual heating system is ineffective or malfunctioning, the vehicle may therefore be extremely uncomfortable or even unhealthy despite the seat heaters. Thus, although the seat heater will operate after its start during its own time, its relatively short period of warming, however, will not be able to improve the conditions in the vehicle in a sufficiently comprehensive manner because the surrounding cold wall seating in the vehicle results in a constant feeling of cold and draft.

On the other hand, DE 30 26 122 discloses a solution as described above for heating the interior of a caravan, camping caravan, caravan or the like, in particular a recreational vehicle. Ko.

The solution 20 is based on the fact that the lining of the said vehicle is preferably provided with an integrated electrical resistance arrangement with a fiberglass reinforced polyester material which is accessible by connecting it to the mains with the vehicle parked at a suitable position. Therefore, such a solution is not known to utilize a resistance arrangement operating directly from the vehicle's electrical system when the vehicle is moving.

The heating system for use in a vehicle according to the present invention is intended to provide a decisive improvement in the above-mentioned disadvantages and thereby substantially increase the state of the art. kan level. To accomplish this purpose, the heating arrangement according to the invention is essentially> ··· characterized in that, particularly when a commercial vehicle, such as a passenger, lorry and / or van, is moving. an electric resistor element included in the auxiliary resistor power supply from the vehicle electrical system is provided above the vehicle seat, such as the front and / or rear bench, such as the side door and / or wall, such as the ta-5 casement, the ceiling, and / or underneath, such as on the floor, for attachment.

The most important advantages of the heating arrangement according to the present invention are its convenience and efficiency, whereby the disadvantages of work-related illnesses and the like, particularly those caused by uncomfortable and healthy conditions, can be effectively prevented both by their practical construction and operation.

The heating arrangement according to the invention preferably comprises electrical resistances arranged on the roof of the vehicle, for example when the vehicle roof is in use, e.g. In this context, it is possible to further apply the invention in such a way that, when the vehicle is in motion, a higher initial heating power is applied to the electric resistors, which decreases after a certain time or at a certain temperature to a lower normal power . As a further advantageous embodiment, it is possible to provide additional electricity. . removable elements for vehicle upholstery

Advantageous embodiments of the heating arrangement according to the invention are disclosed in the dependent claims on the heating arrangement.

In the following description, the invention will be illustrated in detail with reference to the accompanying drawing, in which Figure 1 illustrates a preferred embodiment of the heating arrangement of the invention with a conventional commercial vehicle and Figure 2 illustrates a preferred heating arrangement according to the invention.

The invention relates to a heating arrangement for a vehicle comprising an electrically powered auxiliary resistor arrangement for indirectly heating the driver and / or passenger of the vehicle by substantially increasing the surface temperature of the interior of the vehicle 2 in connection with the vehicle seat x. one or more electric resistance elements arranged Sat. Especially for a commercial vehicle such as a passenger, 1 l »»; when the truck and / or van is moving. the vehicle la is provided on the side of the vehicle seat x such as the front and / or rear seat x, such as a side door and / or wall, such as a rear wall, ':: for mounting on the ceiling and / or below, such as on the floor.

In the preferred embodiment shown in Figure 1, the additional resistance arrangement 1 comprises electrical resistance elements 1a arranged in connection with vehicle roof and rear wall cladding. In addition, the electrical resistance element la positioned in connection with the vehicle door trim 1103155 2a is preferably arranged substantially substantially in the shape of the vehicle seat x.

In a preferred embodiment, each electrical resistance element 1a of the auxiliary resistance arrangement 1 preferably has an electrical power of about 30-100 W. It is further preferred to connect the electrical resistance elements by power control means preferably temperature, time controlled and / or 10 such that 1, the principle of which is illustrated by way of example in Fig. 1 by an arrangement coupled between the electric heating element 1a and the vehicle battery. Preferably, the initial power during the initial heating period of the electric resistor element 1a is 50-100 W and the basic power during the subsequent operating period is about 30-50 W.

Referring to Fig. 2, the electrical resistance element la consists of at least one body part, in connection therewith the electrical resistance elements 1a, such as electrical conductors. or the like. Here, the body member la2 of the electrical resistance element la: 25 comprises a one-way heat transfer material layer la21, such as an aluminum foil or the like and an opposite heat transfer insulating layer la2 ", such as a cardboard, paper sheet, film or the like.

Further, with reference to Fig. 2, the electrical resistance element la of the auxiliary resistor arrangement i 1 is removably arranged in the interior of the vehicle, such as the interior trim. *. for attachment to the outer surface, comprising 35 fastening means 4 preferably operating on a quick-lock principle, such as adhesive, adhesive, locking pin arrangements and / or the like, and more preferably also 6 110315 outer covering 5 such as plastic, leather, fabric coating and / or the like .
