Passenger vehicle, in particular an omnibus

The innovation relates to a passenger vehicle in particular a bus with in the x / corner in the longitudinal direction of the vehicle Running air shafts for ventilation of the passenger area.

The main problem with such buses, which are generally known with air ducts arranged in the ceiling, is to direct the fresh air guided in the air shafts into the vehicle interior in such a way that the individual passengers mutually not be bothered. To solve this problem, it is also known in the undersides of these air shafts to arrange a nozzle for each vehicle seat that is individually adjustable in terms of its sighting and flow rate, so that each passenger has the fresh air supply to his own Can regulate space.

What is disadvantageous about this known system is that the Fresh air supplied to nozzles is always associated with a certain draft and that through the individual adjustability of the amount of air Under certain circumstances, the overall ventilation and in particular the overall ventilation in the passenger area is inadequate .

The task of the present innovation is therefore to provide a forced ventilation that acts centrally for the entire passenger area to create, whereby it is essential that the air inlet into the passenger space, as well as the air outlet under all circumstances to be designed in such a way that the passengers are not amused by drafts.

To solve this problem it is proposed according to the present innovation that the boundary walls of the air exchange Air shafts to the passenger area with a large number of holes are provided and flocked on the passenger side.

The main advantage of this ventilation device according to the invention is to be seen in the fact that the overall very large cross-section area of the totality of the wall holes a correspondingly large amount of air at a low passage speed can be supplied or discharged, and that through Hie application

another very essential reassurance of defilement the air jets passing through the wall holes is achieved, so that very effective ventilation is achieved without the passengers being bothered by sharp jets of air, which are always perceived as drafts will.

In an embodiment of a passenger vehicle according to the innovation, the air shafts should protrude from the roof surface in the shape of a bucket protrude upwards so far that there is a level vehicle interior ceiling.

According to a further feature of the innovation, the air shafts on both sides should be directly next to one, in the middle the ceiling running, light band then be arranged. This further training also contributes to that Occurrence of drafts in the area of the vehicle seats can be ruled out with certainty that the air ducts according to this feature are arranged above the aisle, i.e. to the side of the passenger seats. Another benefit of this Design is that the housing for the Luftscnächte and the light band provided with cable duct as one-piece part can be made and is welded into the roof as a load-bearing part.

According to a further feature of the innovation, the air ducts should be through bulkheads in about the first third of the vehicle be interrupted. This interruption creates a front and a rear air duct section, from one of which can be used to supply fresh air and the other to remove the stale air can. This results in an air flow that circulates in the longitudinal direction of the vehicle and has a high degree of uniformity very good fresh air supply to the passenger area.

According to a further feature of the innovation, motorless, to the outside leading vents, while in the rear section of the air shafts with the outside air in Connected motor fan should be arranged. Due to the arrangement of the roof vents in the front area of the vehicle it is possible to dispense with a fan at this point, as this is the area when the passenger vehicle is moving

j forms a negative pressure zone that automatically removes air from the

Sucks air shafts to the outside. This negative pressure zone falls zxn. ; rear area of the vehicle down, so that in this

'Fan arranged in the area when pumping fresh air

do not have to work against an external negative pressure from the outside into the air shafts.

In addition, air-controlled flaps 13 can also be provided for ventilation at very high temperatures.

Based on the accompanying drawings, an embodiment of a passenger vehicle according to the innovation with a The humpback roof explains:

Fig. 1 is a schematic plan view of a bus with an air duct according to the innovation,

Pig. 2 shows a cross section corresponding to II-II in FIG. 1 enlarged.

In FIG. 1, the outline wall of a bus is denoted by 1, the direction of travel of which is indicated by an arrow 2. In the ceiling 3 of the bus, air ducts 4 and 5 running in the longitudinal direction of the vehicle are arranged, on both sides immediately adjacent to a light band 6 running in the middle of the ceiling 3 in the longitudinal direction, which also includes a cable duct. In approximately the first third of the vehicle, the air shaft 5 is divided by a bulkhead 15 and the air shaft 4 is divided into a front and a rear section by a bulkhead 14. In the front area of the vehicle are in the air shafts 4 and 5 each arranged Entlüftungen'7 ■> 8, while in rückwär- d's

three air flaps are provided. This motor fan 9 1o should be switchable both as an aerator and as a ventilator.

The air shafts 4, 5 are hump-like as far from the roof level placed upwards that the boundary walls 16 with the rest of the roof result in a flat interior ceiling.

The limiting walls 16 of the air shafts 4 and 5 are provided with a plurality of holes 11 and personal space side flocked, from FIG. 2 can be seen, there are the air chess \ _ · and 5 above an aisle in the bus, so that the side of the passenger seats, whereby a nuisance of passengers by draft is excluded from the start.
