The invention has for its object to provide a rotary assembly for a cab, especially for vehicles, as well as a vehicle with at least one pivoting seat, whereby a small space in the cab is claimed when pivoting the seat.

This object is achieved by a rotary arrangement for a driver's cab, in particular for vehicles, which has a lower connection point, in particular for a vehicle floor or for a floor assembly of a vehicle structure, and an upper connection point, in particular on the roof or sky of the driver's cab and lower connection point lie in a common axis and a support structure extends between the upper and lower connection point, which has at least one seat surface, wherein the support structure comprises a support frame comprising at least two pillars extending between the upper and lower connection point and the at least one seat and / or at least one backrest is arranged on the at least two pillars. This rotary assembly has the advantage that the seat is pivotable from a direction of travel position in a lateral or rearward accessibility position and requires little space. The seat may be rotatable about the common axis between the upper and lower connection points. At the same time, the requirements for crash safety when using the rotary assembly in vehicles can be met. In addition, the support structure with the support frame has the advantage that a secure attachment of a three-point or four-point belt system to one of the two or both columns is possible.

Preferably, the seat surface and / or the backrest are arranged between the at least two columns. As a result, a kind of safety frame for the driver can be created. Advantageously, the seat and / or the backrest is adjustable in height, so that an individual adaptation to the respective user can take place.

On each or each column of the support frame, a guide for receiving the seat and / or the backrest is preferably provided. This can be done both the height adjustment of the seat and / or the backrest. At the same time there may be a transverse stiffening of the frame over the seat and / or the backrest. Preferably, guide rails can be provided on or in the column. Alternatively, the column may have a profile in which the guide may be integrated due to the profiling. On the seat and / or the backrest guide elements are provided, which engage the column, in particular on guide rails, on the column.

Furthermore, the support frame preferably has two pillars which are parallel at least in the seating area, which preferably extends along a seat height adjustment and the backrest, and the seat surface is positioned between the parallel sections of the pillars. As a result, the height adjustment of the seat is made possible in a simple manner. Preferably, the columns extend in parallel in an area for adjusting the seat height to a shoulder area or head area of the user. Subsequent thereto, the pillars may be formed facing each other to transition to the upper and lower junctions of the cab rotation assembly.

Preferably, the support structure is formed by a closed support frame, in which the columns in the lower and upper connection point, preferably in each case in a common pivot bearing pass. Alternatively it can be provided that the two columns pass into a common pivot bearing in a lower connection point and engage at the upper connection point on a pivot arm or a cross member. By the upper pivot arm, it is possible that the support frame is arranged at the upper connection point offset from the common axis, whereas the support frame is provided at the opposite connection point by the pivot bearing in the common axis. Thereby, the support structure can be arranged in a tilted orientation. By this tilted arrangement of the support structure, in addition to the reduction of the swing circle diameter, the seat can be provided in a comfortable seating position for different sized driver. In particular, this can be achieved at least in the seating area an inclination of the support frame. This allows for a comfortable sitting position and on the other hand, a rotation of the seat about a common axis with a small space requirement.

A preferred embodiment of the support structure with the closed support frame provides that the at least two pillars, starting from a lower connection point to a head portion of a user of the seat - seen from one side - inclined relative to the common axis, and preferably laterally to a backrest , and then inclined in the opposite direction and merges into the upper junction. Also by this, a tilted or inclined orientation of a support frame in the area of the seated person can be achieved. During a rotational movement of the rotary assembly, the seated person can be rotated about the common axis between the upper and lower connection point.

Furthermore, the upper pivot arm is preferably triangular in shape. Thereby, a closed line of force can be created to initiate the force of the support frame in the pivot bearing.

Preferably, the support structure is made by profiles of a lightweight material. Preferably, extrusion profiles are provided, which are made for example of magnesium or magnesium alloys. Alternatively, composite material can be used which allows a high power consumption, so that the safety is given in the vehicle.

Advantageously, a damping device is provided between the lower connection point and the seat surface, which is preferably also adjustable in the seat height. As a result, the vibrations occurring during the drive can be absorbed.

According to a first embodiment, the damping device is connected via a first joint with the pivot bearing at the lower connection point and via a second joint with the seat surface. This represents a simple structural design. It can also be provided that the second joint between the damping device and the seat is designed as a flexible in several directions spatial joint, so that the seat allows a relaxed sitting even with a longer ride by a wobbling motion ,

Alternatively, between the pivot bearing at the lower connection point and a housing of the damping device, a pivot lever, in particular a pair of pivot levers, be provided and attack the piston of the damping device by means of a joint on the seat. By this pivoting lever, a guided displacement movement of the seat surface in the radial direction to the common axis can be made possible, about which the support structure is rotatable.

Preferably, the seat comprises a seat skeleton and a seat cushion, wherein the seat cushion is arranged longitudinally displaceable on the seat skeleton. Advantageously, the inclination of the seat cushion relative to the seat skeleton can be adjusted. Thereby, the sitting position in a squat position or in a steering wheel position or cockpit position can be changed in a simple manner. Advantageously, a latching rail is provided between the seat cushion and the seat skeleton.

According to a preferred embodiment of the invention, the backrest is firmly connected to the seat. In such a case, it may be sufficient that the seat is guided on the support frame and adjustable in height. Alternatively, in a fixed connection between the backrest and the seat, the backrest is guided on the support frame, and the seat can be supported on a damping device. Also, both the backrest and the seat can be performed together on the columns.

Alternatively, the backrest and the seat can be separated from each other - that is decoupled - and each guided on the support frame. As a result, an increased individual adaptation to the body shapes of the respective driver can be achieved. If this rotation arrangement is to be arranged as a squat seat in order to enable frequent entry and exit, in particular rapid entry and exit, the positioning of the seat area is decisive. If a comfort seat is to be set, in which the driver sits in the seat for an extended period of time, it is necessary to adjust the backrest precisely to avoid back pain. Both are possible by the separate arrangement.

A further preferred embodiment of the invention provides that the backrest comprises a bionic skeleton with lateral wings and preferably the side wings are guided on the support frame. This bionic skeleton has at least one vertically extending web on which the wings are provided laterally. At least wings in the area of the thoracic vertebrae are provided, which extend outwards from the web opposite one another. Preferably, lateral, outwardly extending wings are provided at an upper end of the at least one extending in the vertical direction web, which are provided in the shoulder region. In addition, further laterally extending wings may be provided at a lower end of the vertically extending web. These are arranged in the lumbar region. Preferably, the outer ends of the wings in the thoracic region are connected to the respective opposite columns. In particular, a guide is provided, through which the wings and thus the bionic skeleton along the columns movable and adjustable in height. If the backrest is connected to the seat, this guide can be additionally provided to increase the rigidity of the support frame. As a result, a simple, but also safe arrangement of the backrest is given to the support frame. Alternatively, the bionic skeleton of the backrest may engage additional guide members which are connected to the respective pillar to adjustably receive the backrest in height.

Preferably, the bionic skeleton carries a string. The fabric is arranged in particular at the respective outer ends of the wings of the bionic skeleton, whereby a stretching of the fabric for the backrest takes place. The fabric may be formed as a net covering. Also, a textile material, a fabric or the like may be provided. Other materials can be used for the covering. This provides a comfortable and well-ventilated back support. Advantageously, a thorax support can be provided on the bionic skeleton, whereby the driver can set an improved sitting position.

Preferably, an armrest is attached to the seat. Alternatively, the armrest may also be provided on the backrest or the support frame. The armrest may comprise a control device, in particular a joystick, by means of which the vehicle is controllable.

Furthermore, the rotary arrangement preferably has a protective covering on a rear side of the supporting frame. This protective covering may extend at least over the seating area, in particular in the height from the shoulder or head area to the seat area or a foot area, and in the width at least between the columns. Also, the protective cover may extend between the upper and lower connection point and allows a shielding of the user to the rear. A back of the protective cover can be used to hold an information panel, a display, TVs or other means of communication.

The object underlying the invention is further provided by a vehicle having a vehicle support structure and with a driver's cab arranged on the vehicle support structure which is at least partially surrounded by body structures, the driver's cab having at least one door for accessing the driver's cab laterally or rearwardly to a direction of travel. solved, which comprises in the cab a rotary assembly according to one of the preceding embodiments, whereby the seat is pivotable from a direction of travel position in a lateral or rearward accessibility position. By this rotation arrangement, the seat can be rotated in the cab, with a small space is required.

The user can easily initiate the rotational movement about the axis of rotation fixed in the driver's cab, for example with one foot, in order to move from the direction of travel to the position of entry and exit into and out of the vehicle. As a result, an enlarged space for safety components can be made available in the front of the vehicle structure. Such a rotation arrangement can be provided in particular in vehicles for the transport of persons or goods. These vehicles can represent for example minibuses, shuttle buses or vans. In these vehicles, it may often be necessary for the driver to have to get in and out repeatedly to assist, for example, people getting into the vehicle or to load or unload a transport space in the rear of the vehicle with goods in transit. With regard to future autonomous or semi-autonomous driving of such vehicles, the service function of the driver will continue to come to the fore. Thus, it will become increasingly necessary for the driver or person responsible for the vehicle to be able to comfortably and ergonomically change between the direction of travel position, the position of accessibility and a service position directed toward the interior of the driver's cab. In an autonomous driving of the vehicle, such a service position can also form a comfort or communication position in which the seat is aligned opposite to the direction of travel during the journey. In this position, the driver is allowed to communicate with the passengers or to take a rest position. In the case of autonomous driving, this rotation arrangement also makes it possible for the driver, for example in an emergency situation, to very rapidly swivel from the service position into the direction of travel position in order to take control of the vehicle. The change can be achieved by the rotating assembly in a compact design, since the connection points form the central fulcrum. The support structure extends between the vehicle floor or the floor assembly of the vehicle support structure and the roof of the driver's cab, whereby in addition a stiffening of the vehicle support structure can be achieved. This increases the crash safety.

A preferred embodiment of the vehicle provides that the upper and lower connection point are arranged in a vehicle longitudinal center axis or near the vehicle longitudinal center axis of the vehicle structure. As a result, the seat can be positioned in a central position or near a middle position, in particular far in the front region of the vehicle, so that the driver assumes an optimal position for controlling the vehicle. In addition, the center seat position makes it possible to reduce the country-specific model variety, since the production of special right- or left-hand drive is no longer required. Country-specific specifications may require that the upper and lower connection points for the rotary assembly must be arranged slightly offset from the vehicle longitudinal central axis. Nevertheless, an intermediate seat position can be maintained.

A further preferred embodiment of the vehicle provides that the rotary assembly has a pivoting range, within which the seat from the direction of travel position by at least 60 °, preferably at least 120 °, is pivotable. By providing such a swivel range can be a fast and comfortable, and thus time and cost-saving entry and exit, especially for commercial drivers, be possible.

In particular, the upper and lower connection point can be provided fixed in the cab. The upper and lower connection points may be formed as an upper and lower pivot bearing of the rotary assembly about which the support structure is pivotally mounted. The invention and further advantageous embodiments and developments thereof are described in more detail below with reference to the examples shown in the drawings and explained.

FIG. 1 shows a schematic view of a vehicle 11. This vehicle 11 may be designed as a minibus or shuttle bus and includes a driver's cab 22 for passenger transport. Likewise, the vehicle 11 may be formed as a transport vehicle for carrying goods and, for example, have an open or closed by the bodyworks cargo area. The vehicle 11 includes a vehicle support structure 16 that supports the cab 22. The vehicle support structure 16 may be at least partially clad by the body structures. The vehicle 11 is preferably designed as an electric vehicle. The designated by the numeral 32 arrow defines the direction of travel of the vehicle eleventh

The vehicle 11 has in the rear of the cab 22 a plurality of seats for the passengers, which can be arranged one behind the other and / or next to each other in the cab 22. The passengers and the driver have access to the driver's cab 22 via at least one door 13.

In the front region of the vehicle 11, a seat 12 is provided. On the seat 12, the driver can assume a direction of travel position 14 shown in FIG. 1 for controlling the vehicle 11. It can be provided that this seat 12 is designed as a squat seat, so that the driver controls the vehicle 11 sitting in a squat position. This seat 12 is arranged on a support structure 54. The support structure 54 extends between an upper connection point 17 on the roof 51 of the driver's cab 22 and a lower connection point 18 on the vehicle floor or a floor assembly of the vehicle support structure 16. The upper and lower connection points 17, 18 are arranged in a common axis 19. The upper and lower connection points 17, 18, the central column 54 and at least the seat surface 57, in particular the seat 12, form a rotary arrangement 35. Embodiments of this rotary arrangement 35 will be described below.

This illustration in Figure 1 also illustrates the design of the vehicle support structure 16, which may have a boat-shaped contour. To form this boat-shaped contour, two longitudinal members 21 are brought together at the front to form a bow tip 23. For this purpose, the longitudinal members 21, starting from the nose 23, each have a laterally outwardly pointing curvature 24 and at the rear side have mutually parallel sections. These are spaced from each other by at least one cross member. On the vehicle support structure 16 of the cab 22 is arranged.

The rotary assembly 35 with the seat 12 is preferably arranged in a vehicle longitudinal center axis 55 in the driver's cab 22. This allows the seat 12 serve as a squat center seat. Likewise, the seat 12 can be adjusted as a comfort seat for longer trips. Likewise, it can be provided that the rotary assembly 35 is arranged offset to the vehicle longitudinal central axis 55. The rotary assembly 35 can be arranged in the region of the curvature 21 of the two longitudinal members 21 due to a small pivoting range in the front region of the driver's cab 22. By this far forward arrangement of the seat 12, a larger transport volume can be formed in the rear of the vehicle 11. As a result, more passengers can be accommodated in the cab 22 or a larger amount of goods to be transported.

Due to the rotary arrangement 35, the seat 12 is pivotable from a direction of travel position 14 into an accessibility position 36. In this accessibility position 36, a comfortable and ergonomic entry and exit from the vehicle 11 is made possible. In order to pivot the seat 12 from the direction of travel position 14 into the accessibility position 36, the rotary arrangement 35 has a pivoting region, within which the seat 12 can be pivoted laterally outwards by at least 60 °. The pivoting range can also be at least 120 °, so that an ergonomic accessibility to the seat 12 for the driver is achieved. It can also be provided that the seat 12 can be pivoted by 270 ° or 360 °. As a result, an additional service position 47 or a sitting position relative to the dashboard 26 can be assumed by the driver in addition to the direction of travel position 14 and the accessibility position 36. In this service position 47, the driver can, for example, perform further tasks on a dashboard 26 surrounding the seat 12 or offer further services for the passengers.

FIGS. 2 to 4 show a first embodiment of the rotary arrangement. In this embodiment, the support structure 54 comprises a support frame 41, which is formed by two columns 61, 62. At the upper connection point 17, the two columns 61, 62 are each connected by a pivot arm 44 to the connection point 17. Preferably, the pivot arm 44 is V-shaped. By the pivot arm 44, an inclination of the support structure 54 with respect to the longitudinal axis 48 to the common axis 19 can be adjusted.

The support structure 54 has at the lower connection point 18 on a pivot bearing 66. In this case, the lower ends of the columns 61, 62 may be attached to a turntable, which in turn is mounted on the pivot bearing 66 fixed to the lower connection point 18.

In this embodiment, furthermore, a protective housing is provided in the region of the lower legs.

The seat 12 is disposed between the left and right pillars 61, 62 of the support frame 41. The seat 12 may be recessed relative to the common axis 19 with respect to the common axis 19 on the support structure 54. As a result, the swing circle diameter of the rotary assembly 35 can be reduced.

According to Figure 5, it is possible to pivot the seat 12 through the rotary assembly 35 in the accessibility position 36. In this accessibility position 36, the driver can sit comfortably and ergonomically on the seat 12 and get up to get in or out of the vehicle 11.

The dashboard 26 may at least partially surround the rotary assembly 35. This dashboard 26 can accommodate other functional units in addition to the instruments of a conventional dashboard. Such functional units can serve, for example, an extended service function of the driver. The rotational arrangement 35 enables the driver to pivot the seat 12 from the direction of travel position 14 according to FIG. 1 into such a service position 47 according to FIG. In this service position 47, it is possible for the driver to offer various services to the passengers, for example selling tickets, communicating with the passengers or the like.

In FIGS. 7 and 8, the rotary arrangement 35 according to FIGS. 15 to 20 is shown with an adjusting device 58 for the seat surface 57 or the seat 12. In this case, Figure 6 shows the seat 12 in a low seating position 66 for a small-skinned driver and Figure 5 shows the seat 12 in an elevated seating position 67 for a tall driver. By such adjusting device 58, different seating positions can be adjusted depending on the size of the driver. The adjusting device 58 can be designed as a parallelogram-like adjusting device 58, so that pairs of mutually associated struts engage both in a shoulder region and in a lumbar region of the backrest 56. As a result, when setting from a position close to the tall person support structure 54 to a seating position for a small person, the seat back 56 is not only moved forward in the traveling direction 32 but also moved down toward the seat surface 57 at the same time. The adjustment device 58 can also be provided as a sleeve which can be moved along the support structure 54 and has a lock which can be adjusted in height according to the double arrow 64.

FIGS. 7 and 8 illustrate, by means of the dashed longitudinal axis 48 of the support structure 54, the tilted arrangement of the support structure 54 with respect to the common axis 19. This alternative embodiment of the rotation arrangement 35 can also be modified into a cranked shape.

FIG. 9 shows a front view of a further embodiment of the rotary arrangement 35. FIG. 10 shows a side view, FIG. 11 shows a view from the rear of FIG. 12 of a perspective view of the rotary arrangement 35 according to FIG. 9.

This rotary assembly 35 includes a support structure 54 which is formed as a closed support frame 41. The support frame 41 preferably comprises columns 61, 62 formed from profiles. These can be bent. In particular, lightweight profiles are provided. These columns 61, 62 extending laterally along the vehicle seat 12 merge into a common pivot bearing 66 at the lower connection point 18. The columns 61, 62 pass at the upper connection point 19 into a cross member 102, on which an upper pivot bearing 67 of the upper connection point 19 is provided. Alternatively, the columns 61, 62 can also merge into a common pivot bearing 67 at the upper connection point 17. This pivot bearing 66, 67 is provided fixed to the cab.

The columns 61, 62 form a closed support frame 41. This support frame 41 can have an oval-shaped contour seen from the front. Starting from the lower connection point 18, the columns 61, 62 expand and pass into a seating area 101. In this run the columns 61, 62 parallel. The seating area 101 extends at least from the seat surface 57 to the upper end of the backrest 56 or to the headrest 80. The pillars 61, 62 run parallel in the middle area of the support frame 41. As a result, the seat surface 67 can each be accommodated laterally on the columns 61, 62. In particular, the seat surface 57 is height-adjustable along the columns 61, 62. The parallel sections of the columns 61, 62 are preferably arranged laterally to the seat surface 57. Preferably, the columns 61, 62 are connected to the seat surface 57 in the rear lateral region of the seat surface 57, preferably by guide elements 106.

In the upper region of the support frame 41, the columns 61, 62 extend from the parallel sections of the columns 61, 62 towards one another. Preferably, the upper ends of the pillars 61, 62 may merge into an upper pivot bearing 67 or be secured to the cross member 102.

The support frame 41 is inclined starting from the lower pivot bearing 66 with respect to the common axis 19 in a side view of the support structure 54. The inclination of the lower portion of the columns 61, 62 and the parallel portions of the columns 61, 62 preferably extends to the height of the headrest 80. This inclination preferably extends from the lower end of a foot portion 105 or a lower terminal 18 to the upper end of the headrest Seating area 101. The upper end of the seating area 101 may be the upper end of the backrest 56 or may include the headrest 59. Thereafter, a bend 94 preferably follows, whereby the upper portions of the columns 61, 62 are inclined opposite to the lower part of the columns 61, 62, in order to pass into the upper connection point 18.

In this embodiment, a damping device 68 is provided between the seat surface 57 and the pivot bearing 66. This damping device 68 is preferably adjustable in height to the pivot bearing 66. Between the pivot bearing 66 and the damping device 68, a first joint 69 is provided. Opposite a second hinge 71 is provided, which connects the damping device 68 with the seat surface 57, in particular a seat skeleton 63 of the seat surface 57. The second joint 71 may be formed as a so-called Dondola joint. Preferably, the second joint 71 is deflectable in all directions. As a result, the seat surface 57 may be supported in a wobbling manner relative to the damping device 68.

Furthermore, the seat surface 57 is preferably arranged so as to be longitudinally displaceable and / or adjustable in inclination relative to the seat skeleton 63. This longitudinal displacement is shown by the arrow 73 in Figure 11 and is made possible by a guide. This can be designed as a stepless or provided with locking points guide.

The seat surface 57 is guided in accordance with the embodiment in Figures 9 to 12auch laterally via a guide 74 on the columns 61, 62 of the support frame 41. The guide 74 may be provided as a separate guide rail 110 on the pillars 61, 62. Alternatively, the columns 61, 62 may have a profiling in which the guide rail is integrated. Preferably 57 guide elements 105 are provided on the seat skeleton 63 of the seat surface, which engage in the guide rail 110 of the guide 74 on the columns 61, 62.

The seat 12 preferably comprises the backrest 56. According to a first embodiment, this may be coupled to the seat surface 57. In a height adjustment of the seat 57, the backrest 56 is automatically adjusted. If the backrest 56 is coupled to the seat surface, in particular via a connection section 60, the backrest 56 can be provided without guidance to the pillars 61, 62. This allows a large adjustment range for the backrest 56.

Preferably, the backrest 56 is decoupled from the seat surface 57. In this case, the backrest 56 is also guided with a guide 57 on the columns 61, 62. The backrest 56 may be adjustable independently of the seat surface 57. This allows an individual adaptation to different sized people.

The backrest 56 comprises a bionic skeleton 76. This bionic skeleton 76 receives a covering 79 as a seat cover. This covering may be a net covering, for example made of plastic or a textile material. The fabric can also consist of a fabric. This bionic skeleton 76 includes a vertically extending web 78. Alternatively, a plurality of extending in the vertical direction webs may be provided. At this web 78 laterally projecting wings 77, 83, 85 are provided, which may be provided application-specific in number, shape and / or position. The web 78 has a curved, in particular S-shaped, course. This course can be adapted to the course of the spine. Alternatively, the web 78 may also have a straight course. In an upper region of the web 78 side wings 83 are provided, which form a shoulder support. In the central region of the web 78 middle wings 77 are provided which extend laterally. These wings 77 form a thoracic vertebral support. Preferably, these wings 77 extend laterally outward to a greater extent than the upper wings 83.
