[0004] CAB AND COMMERCIAL VEHICLE

[0005] The present invention relates to a driver's cab for a commercial vehicle, in particular for a military commercial vehicle, and to a commercial vehicle, in particular a military commercial vehicle, with such a driver's cab.

[0006] Military utility vehicles can have both protected and unprotected cabs. Such a cab often features a roof hatch. This is necessary so that crew members have a better view of the terrain from their elevated position. Furthermore, a machine gun, for example, can be mounted on a carriage on the cab roof, which can be manually operated by a crew member via the roof hatch.

[0007] These types of roof hatches can be positioned centrally or offset to the side of the cab roof. A further distinction is made between right-hand and left-hand drive vehicles. Depending on the vehicle type, the roof hatch is usually not located on the driver's side to avoid obstructing their driving. Consequently, the roof hatch is typically positioned centrally or on the side opposite the driver's seat. Roof hatches can be categorized as either hinged or pivoting. Hybrid designs are also possible.

[0008] When designing roof hatches for such cabs, the structural integrity of the cab must be ensured on the roof side, and the roof hatch must not obstruct the driver. Furthermore, it is desirable to allow for easy installation or conversion from left-hand drive to right-hand drive and vice versa, depending on requirements. Solutions exist where the intended side or location of the roof hatch is already considered in the basic cab design. RMM24006PWO DPT24008 WO

[0011] Accordingly, this is already taken into account during the cab's design phase. However, a disadvantage of this approach is that retrofitting or relocating the roof hatch necessitates replacing the entire cab. This involves considerable effort and expense.

[0012] Against this background, one object of the present invention is to provide an improved driver's cab for a commercial vehicle.

[0013] Accordingly, a driver's cab for a commercial vehicle, in particular for a military commercial vehicle, is proposed. The driver's cab comprises a cab roof having a roof opening that penetrates the cab roof, a replaceable roof hatch panel that closes the roof opening at least partially, and a roof hatch cover attached to the roof hatch panel, wherein the roof hatch panel has a roof hatch opening that can be closed by means of the roof hatch cover, wherein the roof opening has a roof hatch opening cross-sectional area, and wherein the roof hatch opening cross-sectional area is larger than the roof hatch opening cross-sectional area.

[0014] Because the roof hatch panel is interchangeable, and because the roof opening cross-sectional area is larger than the roof hatch opening cross-sectional area, it is possible, for example, to mount the roof hatch panel on the cab roof in two positions rotated 180° relative to each other, so that the roof hatch opening can be positioned differently with respect to a transverse direction of the cab. Alternatively, different roof hatch panels can be kept available in a modular system. Depending on the desired application for the cab, a suitable roof hatch panel can then be selected from this modular system. RMM24006PWO DPT24008 WO

[0017] The driver's cab is preferably protected. However, the driver's cab can also be unprotected. In this context, "protected" means specifically that the driver's cab is armored. In particular, the driver's cab is protected against gunfire, booby traps, improvised explosive devices (IEDs), mines, or similar hazards. The driver's cab can also be referred to as the driver's cabin or driver's cab. The driver's cab is suitable for accommodating a crew, for example, a driver and at least one passenger. The driver's cab can, for example, be constructed of or incorporate armored steel plates. However, aluminum alloys, ceramic composites, and / or fiber-reinforced composites can also be used.

[0018] The driver's cab is preferably assigned a coordinate system with a longitudinal direction (x-direction), a transverse direction (y-direction), and a vertical direction (z-direction). Accordingly, the term "longitudinal direction" can be replaced by the term "x-direction." The term "transverse direction" can be replaced by the term "y-direction," and the term "z-direction" can be replaced by the term "vertical direction." The directions are oriented perpendicular to each other.

[0019] The cab preferably comprises a cab shell with a cab front wall, a cab rear wall opposite the cab front wall, two cab side walls opposite each other, and a cab floor. The cab roof is positioned opposite the cab floor. The cab roof is part of the cab shell. A windshield may be mounted on the cab front wall. The windshield may be divided into several windshield sections. Doors may be provided on the cab side walls. RMM24006PWO DPT24008 WO

[0020] Rheinmetall MAN Military Vehicles Austria Ltd.

[0021] 4

[0022] The cab's front wall, rear wall, side walls, roof, and floor enclose the cab's interior and thus separate it from its surroundings. The interior can be accessed from the outside via doors or the roof hatch, as mentioned previously. The cab floor is preferably multi-curved. In particular, at least in sections, the cab floor can have an egg-shaped or ovoid geometry. The cab floor is specifically optimized for mine protection.

[0023] The cab roof preferably comprises a supporting structure, which can, for example, be constructed from interconnected profile beams. In particular, the supporting structure is part of the cab shell or supports the cab shell. The profile beams of the supporting structure can be, for example, rectangular profiles, T-profiles, F-profiles, C-profiles, or the like. The profile beams can be made of, for example, steel or aluminum profile beams. However, fiber-reinforced composite materials can also be used. A combination of the aforementioned materials is also possible. The profile beams can run along and / or diagonally to the longitudinal and / or transverse direction. The profile beams can also run vertically. The supporting structure is truss-like or skeletal.

[0024] The supporting structure also carries, in particular, the outer skin of the cab roof. This outer skin can be made of steel sheet or plate, especially armored steel plate. It can also be made of aluminum sheet or plate. Fiber composite materials and / or ceramic materials can also be used for the outer skin. The outer skin can be composed of several sub-components, which are, for example, welded together. RMM24006PWO DPT24008 WO

[0025] Rheinmetall MAN Military Vehicles Austria Ltd.

[0026] 5

[0027] The cab roof, in particular its outer skin, preferably includes an outer surface against which the replaceable roof hatch panel rests. The roof opening is preferably designed as a cutout or opening that penetrates the cab roof, in particular its outer skin. This means, in particular, that the roof opening connects the interior of the cab with the outside. A reinforcing ring can be provided around the roof opening, attached to an inner surface of the outer skin. The reinforcing ring follows a contour of the roof opening. This means that the reinforcing ring does not have to be perfectly circular.

[0028] The term "replaceable" for the roof hatch panel primarily means that the roof hatch panel can be detachably connected to the cab roof, specifically to the supporting structure, the outer skin, and / or the reinforcing ring. This connection can be made, for example, with screws. However, a permanent connection between the roof hatch panel and the cab roof is also possible. In this case, a welded connection, for example, can be used.

[0029] The fact that the skylight panel "at least partially closes" the roof opening means, in this case, specifically that the skylight panel closes the roof opening up to the skylight opening itself. This means, in particular, that the skylight panel closes the roof opening, but the skylight opening remains enclosed in the area of ​​the roof opening, so that when the skylight is open, the skylight panel covers or conceals the roof opening up to the skylight opening itself.

[0030] The roof hatch cover can be liftable and / or pivotable on the roof hatch panel. The roof hatch cover can be, for example, a hinged roof hatch cover. The roof hatch cover can also be a pivoting roof hatch cover. The roof hatch cover can also be a sliding roof hatch cover. RMM24006PWO DPT24008 WO

[0031] Rheinmetall MAN Military Vehicles Austria Ltd.

[0032] 6

[0033] The roof hatch cover can also be a lift-and-swivel cover. For example, the roof hatch cover can be attached to or connected to the roof hatch panel by means of a lift-and-swivel mechanism. The roof hatch cover is thus movable relative to the roof hatch panel, allowing it to be moved from an open to a closed position and vice versa.

[0034] The roof hatch opening is preferably positioned off-center on the roof hatch panel with respect to the transverse direction. The term "roof hatch cross-sectional area" refers to the cross-sectional area of ​​the roof opening as viewed from a top view of the cab roof. The roof hatch cross-sectional area can, for example, have an elongated geometry. A principal direction of extension of the roof opening preferably runs along the transverse direction.

[0035] Accordingly, the "roof hatch opening cross-sectional area" refers to the cross-sectional area of ​​the roof hatch opening as seen from above on the cab roof. Unlike the roof opening cross-sectional area, the roof hatch opening cross-sectional area can be circular. For example, the roof opening cross-sectional area is 1.5 to 2 times larger than the roof hatch opening cross-sectional area. However, other ratios are also possible.

[0036] According to one embodiment, the roof opening is arranged centrally on the cab roof when viewed along a transverse direction of the cab.

[0037] In particular, the roof opening is preferably positioned centrally between the two cab side walls. The roof opening can optionally also be positioned off-center on the cab roof. RMM24006PWO DPT24008 WO

[0038] Rheinmetall MAN Military Vehicles Austria Ltd.

[0040] According to another embodiment, the roof opening has a larger geometric extent when viewed along the transverse direction than when viewed along a longitudinal direction of the driver's cab.

[0041] In other words, the roof opening has its main direction of extension along the transverse direction. In this context, "main direction of extension" refers to the direction in which the roof opening has its greatest geometric extent. The main direction of extension can therefore coincide with the transverse direction.

[0042] According to another embodiment, the roof hatch opening is arranged off-center on the cab roof when viewed along the transverse direction.

[0043] This allows the roof hatch opening to be positioned as desired. For example, the roof hatch panel can be mounted on the cab roof in two different positions, rotated 180° relative to each other. The roof hatch panel can be rotated 180° around its vertical axis for this purpose. Furthermore, it is possible to provide multiple roof hatch panels in a modular fashion and select a suitable panel depending on the desired position of the roof hatch opening. This allows the cab to be quickly and easily adapted to different applications without having to make structural changes to the cab itself, particularly to the supporting structure.

[0044] According to another embodiment, the roof hatch opening is arranged above a passenger seat or above a middle seat of the driver's cab when viewed along a vertical direction of the cab.

[0045] Preferably, the cab includes a first seat or driver's seat, a second seat or passenger seat, and a third seat or middle seat. The third RMM24006PWO DPT24008 WO

[0046] Rheinmetall MAN Military Vehicles Austria Ltd.

[0047] 8

[0048] The seat is positioned between the first and second seats. The roof hatch opening is preferably not located above the first seat or driver's seat, so that the driver of the commercial vehicle is not impaired or disturbed by the roof hatch opening or the roof hatch cover.

[0049] According to another embodiment, the roof opening has a geometry composed of a rectangle and two semicircles between which the rectangle is arranged.

[0050] The aforementioned geometry thus consists of two parallel and spaced straight lines, each connected by a semicircle. Alternatively, the roof opening can also have a polygonal geometry. For example, it can be hexagonal or octagonal. Furthermore, it can also be oval or elliptical. Basically, the roof opening can have any elongated geometry oriented along the transverse direction.

[0051] According to another embodiment, the roof penetration has several openings that are not connected to each other.

[0052] However, the unconnected openings can be completely covered using the roof hatch cover.

[0053] According to a further embodiment, the cab has a cab shell which includes the cab roof, wherein the cab shell encloses an interior space of the cab, and wherein the roof hatch panel is arranged outside the interior space. RMM24006PWO DPT24008 WO

[0054] Rheinmetall MAN Military Vehicles Austria Ltd.

[0055] 9

[0056] In particular, the roof hatch panel is connected to the exterior of the cab shell, especially the cab roof. For example, the roof hatch panel rests on the aforementioned exterior surface of the cab roof, specifically the outer skin of the cab roof. The roof hatch panel may be screwed to the cab roof. In particular, the roof hatch panel may be connected to the supporting structure, the outer skin, and / or the reinforcing ring of the cab roof.

[0057] According to another embodiment, the roof hatch plate is detachably connected to the cab roof, in particular screwed to it.

[0058] For example, a riveted or bolted connection may be used. Additionally or alternatively, the roof hatch panel may be permanently attached to the cab roof. In this case, a welded connection may be used. In particular, the roof hatch panel is detachably connected to the supporting structure, the outer skin, and / or the reinforcing ring.

[0059] According to another embodiment, the roof hatch cover can be moved from an open state, in which the roof hatch cover releases the roof hatch opening, to a closed state, in which the roof hatch cover closes the roof hatch opening, and vice versa, by means of a combined lifting and pivoting movement.

[0060] To move the roof hatch cover from the open to the closed position, the cover is first pivoted around a rotation axis and then lowered in the opposite direction to the upward movement. The same applies to moving the roof hatch cover from the closed to the open position. For this, the roof hatch cover is first lifted along the upward direction and then pivoted around the aforementioned axis. RMM24006PWO DPT24008 WO

[0061] Rheinmetall MAN Military Vehicles Austria Ltd.

[0062] The roof hatch cover pivots. It can be described as a lift-and-swivel roof hatch cover. Alternatively, it can simply tilt. In this case, it is a hinged roof hatch cover or can be described as such.

[0063] According to another embodiment, the driver's cab has a lifting and swiveling device attached to the roof hatch plate, which connects the roof hatch cover to the roof hatch plate in order to achieve the combined lifting and swiveling movement of the roof hatch cover.

[0064] The lifting and pivoting mechanism is associated with the aforementioned axis of rotation around which the roof hatch cover can be pivoted. The lifting and pivoting direction connects the roof hatch cover to the roof hatch panel in a pivoting or movable manner. The lifting and pivoting mechanism is mounted on the roof hatch panel. For example, the lifting and pivoting direction can be achieved through an opening provided in the roof hatch panel. The lifting and pivoting mechanism also allows the roof hatch cover to be locked in both the open and closed positions. This prevents the roof hatch cover from being opened or closed unintentionally. In the closed position, the roof hatch cover can be locked at a stop or locking point provided on the cab roof, particularly on the outer skin.The roof hatch cover is therefore preferably locked not to the roof hatch plate, but directly to the cab roof.

[0065] According to a further embodiment, the driver's cab has a first end stop and a second end stop attached to the roof hatch plate, wherein the roof hatch cover rests against the first end stop in the open state and rests against the second end stop in the closed state. RMM24006PWO DPT24008 WO

[0066] Rheinmetall MAN Military Vehicles Austria Ltd.

[0067] 11

[0068] The first and / or second end stop can each be equipped with rubber buffers. The first end stop prevents the roof hatch cover from moving beyond its position when open. Similarly, the second end stop prevents the roof hatch cover from moving beyond its designated end position when closed.

[0069] According to another embodiment, the roof hatch plate has a projection extending laterally out of the roof hatch plate, to which the first end stop is attached.

[0070] Preferably, the roof hatch plate is polygonal, in particular octagonal. A projection preferably extends from one side edge of this octagonal geometry. The first end stop can, for example, be welded to the projection.

[0071] According to another embodiment, the roof hatch opening is circular.

[0072] Alternatively, the roof hatch opening can also be polygonal, for example hexagonal. It can also be oval or at least slightly oval. However, a circular roof hatch opening is particularly preferred.

[0073] According to another embodiment, the roof hatch plate is polygonal, in particular octagonal.

[0074] As mentioned previously, the extension protrudes laterally from the roof hatch plate. Alternatively, the roof hatch plate can also be rounded. The roof hatch plate can also be rectangular. RMM24006PWO DPT24008 WO

[0077] Furthermore, a commercial vehicle, in particular a military commercial vehicle, with such a driver's cab is proposed.

[0078] The commercial vehicle can be a truck. In particular, the commercial vehicle is an off-road truck. The commercial vehicle is a multi-axle vehicle. The commercial vehicle can be a two-axle, three-axle, four-axle, or five-axle vehicle. The commercial vehicle preferably includes all-wheel drive. The commercial vehicle can therefore also be referred to as an all-wheel-drive commercial vehicle. The commercial vehicle can be a protected commercial vehicle. The commercial vehicle includes the driver's cab, which is supported by a chassis. Furthermore, the commercial vehicle can have an interchangeable body, which is also supported by the chassis. The commercial vehicle can be armed or unarmed.

[0079] The embodiments and features described for the proposed driver's cab apply accordingly to the proposed commercial vehicle and vice versa.

[0080] The term "one" here should not necessarily be understood as restricting the number to exactly one element. Rather, it can also refer to multiple elements, such as two, three, or more. Similarly, every other counter used here should not be interpreted as restricting the number to the exact number stated. Instead, numerical deviations, both higher and lower, are possible unless otherwise specified.

[0081] Other possible implementations of the driver's cab and / or the commercial vehicle also include combinations of features or embodiments described previously or subsequently with regard to the exemplary embodiments, even if not explicitly mentioned. The person skilled in the art will also recognize individual aspects as RMM24006PWO DPT24008 WO

[0082] Rheinmetall MAN Military Vehicles Austria Ltd.

[0083] Add 13 improvements or additions to the respective basic shape of the driver's cab and / or the commercial vehicle.

[0084] Further advantageous designs and aspects of the cab and / or the commercial vehicle are the subject of the dependent claims and the exemplary embodiments of the cab and / or the commercial vehicle described below. The cab and / or the commercial vehicle are further explained below with reference to preferred embodiments and the accompanying figures.

[0094] Fig. 8 shows another schematic perspective view of the roof hatch arrangement according to Fig. 7! and

[0095] Fig. 9 shows a schematic perspective view of an embodiment of a roof hatch plate for the roof hatch arrangement according to Fig. 7.

[0096] In the figures, identical or functionally equivalent elements have been given the same reference symbols, unless otherwise indicated.

[0097] Fig. 1 shows a schematic side view of an embodiment of a commercial vehicle 1.

[0098] Commercial vehicle 1 is a land vehicle. Commercial vehicle 1 is specifically a military commercial vehicle. Commercial vehicle 1 can therefore also be referred to as a military commercial vehicle. Commercial vehicle 1 can be a truck. Specifically, commercial vehicle 1 is an off-road truck. Commercial vehicle 1 can be a protected vehicle. Therefore, commercial vehicle 1 can also be referred to as a protected commercial vehicle.

[0099] The commercial vehicle 1 is assigned a coordinate system with a longitudinal direction (x-direction), a transverse direction (y-direction), and a vertical direction (z-direction). The x, y, and z directions are oriented perpendicular to each other. The z-direction is oriented parallel to a gravity direction (g). In the orientation shown in Fig. 1, the gravity direction (g) is oriented from top to bottom.

[0100] Commercial vehicle 1 is a wheeled vehicle. Commercial vehicle 1 comprises a chassis 2 with a plurality of axles 3, 4, 5, 6. Each of the axles 3, 4, 5, 6 is assigned at least one pair of wheels 7, 8, 9, 10. For example, RMM24006PWO DPT24008 WO

[0101] Rheinmetall MAN Military Vehicles Austria Ltd.

[0102] 15. Four axles 3, 4, 5, 6 are provided. This means that the commercial vehicle 1 is a four-axle vehicle in this case. However, the number of axles 3, 4, 5, 6 is arbitrary. The commercial vehicle 1 can also be a two-axle, three-axle, or five-axle vehicle. The commercial vehicle 1 preferably includes all-wheel drive. This means that all axles 3, 4, 5, 6 can be driven. The commercial vehicle 1 can therefore also be referred to as an all-wheel-drive commercial vehicle. At least one of the axles 3, 4, 5, 6 is steerable. Preferably, two front axles or front axles 3, 4 are steerable. All axles 3, 4, 5, 6 can also be steerable.

[0103] The chassis 2 carries a cab 11 of the commercial vehicle 1. The cab 11 can also be referred to as the driver's cab or driver's cabin. The cab 11 is preferably protected against gunfire, booby traps, improvised explosive devices (IEDs), mines, or the like. The cab 11 encloses an interior space 12 in which a crew of the commercial vehicle 1, for example, a driver and one or two passengers, can be located. The cab 11 encloses the interior space 12 and thus separates it from the surrounding area 13. The interior space 12 is accessible from the surrounding area 13 by means of openable doors 14.

[0104] The chassis 2 is suitable for carrying an interchangeable body 15 of the commercial vehicle 1 in addition to the driver's cab 11. The body 15 can be, for example, a flatbed, a container, a box body, a tank, or the like. Figure 1 shows a body 15 in the form of a container.

[0105] The commercial vehicle 1 can move along a surface 17 in a direction of travel 16 using its wheels 7, 8, 9, 10. The direction of travel 16 is oriented opposite to the x-direction x. However, this does not preclude the commercial vehicle 1 from moving – for example, in reverse – in the opposite direction to the RMM24006PWO DPT24008 WO

[0106] Rheinmetall MAN Military Vehicles Austria Ltd.

[0107] 16. The vehicle can move in the direction of travel 16 on the surface 17. The surface 17 can be a road or any terrain.

[0108] Fig. 2 shows a schematic front view of an embodiment of a driver's cab 11 as previously mentioned for the commercial vehicle 1.

[0109] The aforementioned coordinate system with directions x, y, z can also be assigned to the cab 11. The cab 11 comprises a mine-protected, in particular mine-protection-optimized, cab floor 18 and a cab shell 19, which is firmly connected to the cab floor 18. The cab floor 18 is, in particular, part of the cab shell 19. The cab shell 19 has a cab roof 20 arranged opposite the cab floor 18, two cab side walls 21, 22 arranged opposite each other, in particular a first cab side wall 21 and a second cab side wall 22, which may be equipped with doors 14 as mentioned above, a cab front wall 23, and a cab rear wall (not shown) arranged opposite the cab front wall 23. The cab front wall 23 may have a windshield 24. The windshield 24 can be divided into two windshield sections 25, 26.However, the windshield 24 can also be a single piece.

[0110] The cab floor 18 and the cab shell 19 enclose the interior 12. The interior 12 can be accessed from the surroundings 13 by means of the aforementioned doors 14 and / or hatches (not shown). A first seat 27, a second seat 28, and a third seat 29 are accommodated in the cab 11 and thus located within the interior 12. The first seat 27 can also be referred to as the driver's seat. The second seat 28 can also be referred to as the passenger seat. The third seat 29 can also be referred to as the middle seat, since, viewed along the y-direction y, it is positioned midway between seats 27 and 28. RMM24006PWO DPT24008 WO

[0111] Rheinmetall MAN Military Vehicles Austria Ltd.

[0112] 17

[0113] Seats 27, 28, and 29 are positioned side-by-side and spaced apart along the y-direction y. The third seat, 29, is positioned above the first seat, 27, and the second seat, 28, along the z-direction z. The third seat, 29, can also be positioned centrally within the driver's cab 11 when viewed along the y-direction y. Seats 27, 28, and 29 are separate components and can be individually replaced. Therefore, seats 27, 28, and 29 do not form a continuous bench seat.

[0114] Fig. 3 shows a schematic perspective view of an embodiment of a cab roof 20 as previously mentioned. Fig. 4 shows a schematic underside view of the cab roof 20. Fig. 5 shows another schematic perspective view of the cab roof 20. Fig. 6 shows another schematic perspective view of the cab roof 20. Reference is made to Figs. 3 to 6 simultaneously below.

[0115] The cab roof 20 has a supporting structure 30, which is formed, for example, from interconnected profile beams 31, of which only one is labeled with a reference numeral in Fig. 4. The profile beams 31 can be, for example, rectangular profiles, T-profiles, I-profiles, C-profiles, or the like. The profile beams 31 can be, for example, steel profile beams or aluminum profile beams. However, fiber-reinforced composite materials can also be used. A combination of the aforementioned materials is also possible. The profile beams 31 can run along and / or obliquely to the x-direction x and / or the y-direction y. The profile beams 31 can also run along the z-direction z. The supporting structure 30 is truss-like or skeletal.

[0116] The supporting structure 30 carries an outer skin 32 of the cab roof 20. The outer skin 32 can be a steel sheet or a steel plate, in particular an armored steel plate. The outer skin 32 can also be an aluminum sheet or an RMM24006PWO DPT24008 WO

[0117] Rheinmetall MAN Military Vehicles Austria Ltd. 18

[0118] The outer skin 32 can be made of aluminum. Fiber composite materials can also be used for the outer skin 32. The outer skin 32 can be composed of several sub-components, which are, for example, welded together. The outer skin 32 has an outer surface 33, which faces the environment 13 and away from the interior 12, and an inner surface 34, which faces the interior 12 and away from the environment 13.

[0119] A roof opening 35 is provided in the cab roof 20, particularly in the outer skin 32. The roof opening 35 penetrates the cab roof 20. The roof opening 35 is specifically designed as a cutout or opening that connects the interior 12 with the surroundings 13. The roof opening 35 has a cross-sectional area 36, ​​shown hatched in Figures 3 and 4.

[0120] A first anchor point 37, a second anchor point 38, and a third anchor point 39 are provided at the roof opening 35. The anchor points 37, 38, 39 are arranged within the interior space 12. Preferably, exactly three anchor points 37, 38, 39 are provided. The anchor points 37, 38, 39 can be attached to the outer skin 32. The outer skin 32 can be reinforced in the area of ​​the anchor points 37, 38, 39 by means of a reinforcing ring 40. The reinforcing ring 40 follows a geometry or contour of the roof opening 35. The anchor points 37, 38, 39 can also be referred to as locking points. The reinforcing ring 40 can support the anchor points 37, 38, 39. The anchor points 37, 38, 39 can be part of the reinforcing ring 40.

[0121] Viewed along the y-direction y, the roof opening 35 is located centrally on the cab roof 20. In other words, the roof opening 35 is positioned centrally between the two cab side walls 21, 22. The roof opening 35 has an elongated geometry, the RMM24006PWO DPT24008 WO

[0122] Rheinmetall MAN Military Vehicles Austria Ltd.

[0123] 19. The main direction of extension is along the y-direction y. Thus, the roof opening 35 has a larger geometric extent when viewed along the y-direction y than when viewed along the x-direction x. In particular, the roof opening 35 has a geometry composed of a rectangle and two semicircles between which the rectangle is arranged.

[0124] The cab roof 20 further comprises a roof hatch assembly 41 mounted on the cab roof 20. The roof hatch assembly 41 is not shown in Figures 3 and 4. The roof hatch assembly 41 has a replaceable roof hatch panel 42, which closes the roof opening 35 at least partially. For example, the roof hatch panel 42 is mounted on the outside of the cab roof 20. For example, the roof hatch panel 42 can rest on the outer surface 33 of the outer skin 32 and be connected to the outer skin 32, the reinforcing ring 40 and / or the supporting structure 30, in particular by screws.

[0125] In addition to the roof hatch plate 42, the roof hatch assembly 41 has a roof hatch cover 43, which is attached to the roof hatch plate 42. The roof hatch cover 43 can be moved by means of a folding motion or by means of a combined lifting and pivoting motion from an open state ZI shown in Fig. 5, in which the roof hatch cover 43 exposes a roof hatch opening 44 in the roof hatch plate 42, to a closed state Z2 shown in Fig. 6, in which the roof hatch cover 43 conceals or closes the roof hatch opening 44. The roof hatch opening 44 is a cutout or opening provided in the roof hatch plate 42 that penetrates the roof hatch plate 42.

[0126] In contrast to the roof opening 35, the roof hatch opening 44 is not elongated, but preferably has a circular geometry. The RMM24006PWO DPT24008 WO

[0129] The roof opening 35 can also be rectangular, particularly if the driver's cab 11 is protected. Viewed along the y-direction y, the roof hatch opening 44 is not located centrally on the driver's cab roof 20, but rather off-center. Specifically, viewed along the z-direction z, the roof hatch opening 44 is located above the second seat 28 or above the third seat 29.

[0130] Fig. 7 shows a schematic perspective view of one embodiment of the roof hatch assembly 41 mentioned above. Fig. 8 shows another schematic perspective view of the roof hatch assembly 41. Fig. 9 shows a schematic perspective view of one embodiment of the roof hatch plate 42 mentioned above. Reference is made hereafter to Figs. 7 to 9 simultaneously.

[0131] As previously mentioned, the roof hatch assembly 41 comprises a roof hatch panel 42 and a roof hatch cover 43. The roof hatch opening 44 of the roof hatch panel 42 has a roof hatch opening cross-sectional area 45, which is shown hatched in Fig. 9. The roof opening cross-sectional area 36 of the roof opening 35 is larger than the roof hatch opening cross-sectional area 45 of the roof hatch opening 44. For example, the roof opening cross-sectional area 36 is 1.5 to 2 times larger than the roof hatch opening cross-sectional area 45. The roof hatch panel 42 has an annular flange 46 surrounding the roof hatch opening 44. The roof hatch cover 43 rests against the annular flange 46 in the closed state Z2. The annular flange 46 may include a sealing device.

[0132] The roof hatch plate 42 has a polygonal geometry. In particular, the roof hatch plate 42 can have an octagonal geometry, as shown in Fig. 9 with the aid of a dashed line. A projection 47 extends laterally from the roof hatch plate 42, at which a first end stop 48 is located.

[0133] Rheinmetall MAN Military Vehicles Austria GmbH 21 is attached to the roof hatch cover 43. The first end stop 48 can, for example, have a rubber buffer.

[0134] In the open position ZI, the roof hatch cover 43 rests against the first end stop 48. Furthermore, a second end stop 49 is mounted on the roof hatch plate 42. The second end stop 49 may also have a rubber buffer. In the closed position Z2 of the roof hatch cover 43, the roof hatch cover 43 rests against the second end stop 49.

[0135] As mentioned previously, the roof hatch cover 43 can be moved from the open state ZI to the closed state Z2 and vice versa by a combined lifting and pivoting movement. For this purpose, a lifting and pivoting device 50 is attached to the roof hatch plate 42. The lifting and pivoting device 50 connects the roof hatch cover 43 to the roof hatch plate 42 to enable the combined lifting and pivoting movement of the roof hatch cover 43.

[0136] With the aid of the lifting and swiveling device 50, it is possible to first swivel the roof hatch cover 43 about a pivot axis 51 and then lower it in the opposite direction z to move the roof hatch cover 43 from the open state ZI to the closed state Z2. To move the roof hatch cover 43 from the closed state Z2 to the open state Z1, the roof hatch cover 43 is first lifted along the z-direction z and then swiveled about the pivot axis 51.

[0137] The lifting and swiveling device 50 is mounted, in particular, on an opening 52 provided in the roof hatch panel 42. The roof hatch cover 43 includes an externally located rib 53 that extends radially beyond the roof hatch cover 43. The lifting and swiveling device 50 is connected to the rib 53. The lifting and swiveling device 50 is optional. RMM24006PWO DPT24008 WO

[0140] Alternatively, the roof hatch cover 43 can also be a hinged roof hatch cover. In the closed state Z2, the roof hatch cover 43 can be locked at at least one of the hinge points 37, 38, 39. To configure the driver's cab 11, roof hatch panels 42 with different roof hatch openings 44 can be used. These can be stored in a modular fashion. Alternatively, the roof hatch panel 42 can also be mounted rotated by 180° in contrast to the illustration in Figures 5 and 6, so that the roof hatch opening 44 is not offset to the left in the orientation shown in Figures 5 and 6, but rather offset to the right.

[0141] It is therefore possible, for example, to position the roof hatch opening 44 either above the second seat 28 or above the third seat 29. Conversion is easily accomplished by disassembling and reassembling the roof hatch assembly 41.

[0142] Although the present invention has been described using exemplary embodiments, it can be modified in many ways.
