Furthermore, the invention relates to a seat for a service and special vehicle, wherein the seat is fixed with a seat and a backrest in a loading space for transporting or persons on a displacement device for moving the seat of a fixed seat support, wherein the seat support only is attached to a side wall and / or only on a wheel well and the seat is provided on the seat support laterally displaceable with a plurality of detent positions for locking the seat at different distances to the side wall of the cargo space. description

Special and emergency vehicles, such as ambulance or fire engines, often have a cargo space in which people are transported. These are in particular also so-called box bodies. The persons sit in the loading space on seats, which are fixed with a seat holder in the hold. In Ambulanzfahrzeugen also be used for the transport of sick or injured persons also Fahrtragen. Seats and car transporters are simultaneously fixed next to each other in the loading area of the ambulance vehicle. Paramedics or doctors come in such constellations only bad to an injured or sick person, which is on the stretcher, approach to supply. Therefore, the seat must be arranged as space-saving as possible.

State of the art

From DE 20 2009 015 652 Ul an ambulance seat for ambulance and special vehicles with a seat and a backrest is known, which is fixed to a wall and / or on a frame of the vehicle, wherein the seat hinged via a hinge connected to the backrest is, so that the seat is folded in a working position substantially horizontally and in a rest position substantially vertically to the backrest, and a safety belt to fix a person to the ambulance seat in an accident of the vehicle. In addition to the vehicle seats for emergency services or service personnel in the driver's cab is for a rescue vehicle such. B. an ambulance, an additional seat needed as an ambulance seat. This seat is preferably attached to a wall of the ambulance. This seat is then available, for example, to a doctor, nurse or even for a patient. The person sitting there is fixed while driving in the vehicle with a safety belt to prevent personal injury in the event of accidents or sudden braking. To have as much room as possible, the seat is wegschieb- or foldable formed. These seats are not intended for children. If a child on one seat such an extra child seat must be used. Because of the already small storage space of emergency vehicles such child seats are therefore often not carried. If a child is transported in such a seat, it is thus often inadequate, bad or even not secured in an accident or emergency braking.

DE 32 19 710 Al discloses a vehicle seat for at least two people. The vehicle seat consists of a base with supports, which are connected with spars. On the spars at least two seat parts are arranged with hinged backrest parts. At least one seat surface part is mounted transversely displaceable and lockable on the spars. The spars are formed with respect to their height over the footprint of the seat in a straight line and both seat parts in basically the same way over the spars movable.

DE 10 2007 044 319 A1 describes a vehicle seat having a seat part and a base frame connected to the seat part, the base frame having at least one first rail element for displacing the seat part. The first rail element is connected to one another in a first plane and at least one second rail element for displacing the seat part in a second plane by means of a rotating device such that their mutual alignment is variable.

Often, items such as clothing or the like. Lie on the seat, because the space required in the cargo space is very tight. The known seats in ambulance and special vehicles have the disadvantage that the seat disappears to make room. This is done by folding or moving the seat. The seat is then no longer available. In rail systems for seats, the rails or corresponding underframes do not change their position in the cargo space. They remain disturbing in their place. Disclosure of the invention

The object of the invention is therefore to provide a way to optimally and in spite of an additional seat the space in a cargo space of a service or special vehicle

5 safe to use.

According to the invention the object is achieved in that in an application and special vehicle of the type mentioned above, the seat on the seat bracket laterally displaceable with several locking positions for detecting the seat in different

10 distances to a side wall of the cargo space is provided with a telescopically shaped displacement device. Furthermore, the object is achieved accordingly, that in a seat for an emergency and special vehicle of the type mentioned the seat is provided with a telescopically shaped displacement device for the seat slidably.

15 Due to the possibility of moving the seat sideways in the loading space of a service vehicle and a special vehicle, the small space used during loading can be used differently than when driving. The seat is moved to the side. The seat is not moved on a base or the like., But the entire telescopic sliding device of the seat holder is moved together with seat. The seat mount is

20 thereby formed like a telescopic arm, at one end of the seat is attached. In a completely collapsed state of the telescopic sliding device of the seat support, the seat is as close as possible to the side wall of the cargo space. Between a stretcher and the seat can thus arise a free passage without disturbing bases for the seat. In undressed

25 state of the displacement device, for example, a companion gets very close to a patient on a stretcher. During the journey, it is very useful that the companion is very close to the patient for addressing and care.

BO It is advantageous that the seat holder is attached only to a side wall and / or wheel arch. Often the seat mount will be at the bottom of the cargo space attached. As a result, it is difficult to put anything under the seat. In addition, a cleaning is then possible below the seat only between the interstices of the seat holder. Cleaning the cargo space is made more difficult. By attaching the seat bracket to the side wall space for stowing objects and also for better cleaning is created below the seat. The space in the hold of a service and special vehicle, such as an ambulance, is extremely limited. Every conceivable room is used here. Conveniently, the displacement device is therefore arranged on a wheel well. In this way, it is particularly avoided that not unnecessarily space is consumed in this hold, but a place in the hold, which could otherwise be used only very cumbersome or expensive.

The telescopic shifter allows only a lateral movement. This lateral movement is prevented by the locking positions while driving with the vehicle. The displacement device can also be actuated electrically and / or hydraulically. For this purpose, an electric motor or hydraulic drive is then required in each case. A remote control can also help the person move the seat sideways to keep hands free for other purposes.

The displacement device is formed telescopically. The displacement device forms a collapsible or expandable arm. Here are, for example, square and / or round profile strips with different diameters, which are suitably inserted into each other. But also rail-like elements that can be pushed together with and possibly without bearings. The seat can be moved so stable against the side wall of the cargo space to the side. At least two similar moldings with different circumference engage each other. This can be achieved for example by at least two pipe profiles with different diameters. As a result, the seat can be guided linearly along this profile strips or tube profiles laterally on the seat support.

An advantageous embodiment of the insert and special vehicle according to the invention is that the seat support vertically and / or horizontally is designed. Due to the swiveling, the seat can be moved horizontally anywhere in the free space. A companion can thereby accomplish many things without getting up from the seat. Furthermore, the seat can be adapted to a desired height for a companion, whereby this can get a comfortable and comfortable sitting position.

At the telescopic shifter, a person can easily pinch and / or injure his fingers. In a further advantageous embodiment of the insert and special vehicle according to the invention, therefore, a bellows is provided as injury protection on the displacement device.

An advantageous embodiment of the insert and special vehicle according to the invention is achieved in that the variable displacement distance of the seat is greater than 200 mm. As a result, the seat is guided as far as possible from the seat support. He can be very tight, for example, be performed on a stretcher in a carriage. Because of the forces that can act on such a seat, the prior art, for example, a subframe is used, which is attached to at least two points as far apart as possible to achieve a lateral displacement of more than 200 mm. The spaced two-point attachment can be completely avoided with the telescopic displacement device.

In a preferred embodiment of the insert and special vehicle according to the invention, the seat is designed to be rotatable and / or hinged. As a result, an accompanying person in the hold has the greatest possible freedom of movement, for example, to supply a patient during a journey by the patient. This companion can also easily get into medicine stashed cabinets or cutlery without leaving the seat.

Further embodiments and advantages will become apparent from the subject of the dependent claims and the drawings with the accompanying descriptions. Embodiments are explained below with reference to the accompanying drawings. The invention should not be limited solely to these listed embodiments. They are only intended to illustrate the invention. The present invention is intended to refer to all objects which now and in the future the skilled person would take as obvious to the realization of the invention. Short description of the drawing

The seat support 30 is attached only to the one wheel housing 18, so that the telescopic sliding device 32 laterally thereof into the free space, gap 46, projects. Instead of the wheel arch 18, the seat support 30 may also be attached to the corresponding side wall 14 which is located on the side of the wheel arch 18. The attachment may also consist of a combination on the wheel arch 18 and side wall 14. The seat 34 consists of a seat surface 36 and a backrest 38 with a headrest 39. On the backrest 38 here not visible seat belts are attached. The seat 34 is rotatably mounted on the telescopic sliding device 32 by means of a turntable assembly 40 about a vertical axis A (see FIG. 2). The seat 36 is pivotally provided about an axis B (see FIG. 2) so that it can be folded against the seat back 38.

The telescopic sliding device 32 also has locking positions 41. A spring-loaded pin 42 of the displacement device 32 engages in detent bores 44 in certain positions for locking. The extract of the displacement device 32 can be set variably in this way. The seat 34 can be displaced laterally by means of the displacement device 32 of the seat holder 30. The suitable position is finally determined by means of the locking positions 41.

In the collapsed state of the displacement device 32, as shown in this figure 1, for example, creates an additional usable space 46 between the stretcher 28 and the support table 26 and the seat 34. This space can be used, for example, a patient on the stretcher 28th as well as possible to reach from many sides.

FIG. 2 likewise shows a schematic schematic diagram of the loading space 10 according to FIG. 1 with the laterally displaceable seat 34 from the front. As far as this Fig. 2 corresponds to Fig. 1, the same reference numerals are used. For clarity, only the wall 14 is shown here. On the other walls or ceiling was omitted in this presentation.
