DRIVER'S SEAT FOR A RAIL VEHICLE

Abstract

A driver's seat for a rail vehicle includes a seat, a frame, a support, a fastening unit and a compressed air line, ensuring compressed-air-assisted functionalities of the driver's seat. The frame supporting the seat is mounted rotatably and connected to a first end of the support permitting the seat to rotate about an axis of the support. A second end of the support is connected to the fastening unit, fastening the seat in a vehicle control console. The air line ensures compressed-air-assisted seat functionalities and has a first region with partial coils running around the support at a predefined distance. The partial coils are formed and fastened such that rotational movement of the seat effects a change in distance of the partial coils relative to the support. The partial coils of the air line form a spiral, wound around the support at a predefined distance.

Description

[0041] The present invention will be explained in more detail below by way of example with reference to a drawing, in which:

[0042] FIG. 1 shows a configuration of the driver's seat according to the invention, and

[0043] FIG. 2 shows an advantageous development of the driver's seat according to the invention with reference to FIG. 1.

[0044] FIG. 1 shows a configuration of the driver's seat FS according to the invention.

[0045] The driver's seat FS includes compressed-air assisted functionalities which are functionally ensured and implemented via a compressed air line DLG, which is part of the driver's seat FS.

[0046] The driver's seat FS has a seat SIT, a frame RAH, a support TRG and a fastening unit BFE.

[0047] The seat SIT is connected to a first end of the support TRG via the frame RAH, which supports the seat SIT. A second end of the carrier TRG is connected to the fastening unit BFE.

[0048] The seat SIT is designed for use by a rail vehicle driver and is rotatably mounted about an axis of the support TRG.

[0049] The fastening unit BFE is designed for a fastening of the support TRG in a control console of the rail vehicle (not specifically illustrated here).

[0050] The compressed air line DLG in a first region B1 is implemented as at least one partial coil, which runs radially around the support TRG.

[0051] The at least one partial coil is formed and fastened in such a way that a rotational movement of the seat SIT effects a change in the radius of the partial coil.

[0052] Thus, the radius change compensates for the rotational movement of the seat SIT that is carried out.

[0053] The compressed air line DLG in a second region B2 is implemented as at least one partial loop. This partial loop is formed and fastened in such a way that a translational movement of the seat SIT is compensated by a change in shape of the partial loop.

[0054] The frame RAH which supports the seat SIT is rotatably connected to a first end of the support such that the seat is rotatable.

[0055] The second end of the support TRG is arranged opposite the first end of the support TRG. Here, the support TRG is formed as a tube, which is arranged standing substantially vertically between the fastening unit BFE and the frame RAH.

[0056] A pneumatic suspension and/or pneumatic seat adjustment, to which the compressed air line DLG is fed to implement the pneumatic functionality, is arranged between the frame RAH and the seat SIT.

[0057] The first region B1 of the compressed air line DLG (with the at least one partial coil) is connected at its first end to the fastening unit BFE and by its second end to the frame RAH. As a result, it is fixed such that the above-described change in radius of the at least one partial coil is permitted.

[0058] In a preferred development, the second region B2 of the compressed air line (with the at least one partial loop) is connected at its first end to the seat SIT and to the pneumatic suspension and/or to the pneumatic seat adjustment, while its second end is connected to the frame RAH. As a result, it is fixed such that the above-described change in shape of the partial loop is permitted.

[0059] The partial coil is produced from an elastic rigid material, for example from polyamide or the like.

[0060] As illustrated here, a plurality of partial coils of the compressed air line DLG form a spiral, which is wound around the support TRG at a predefined distance from the support TRG.

[0061] FIG. 2 shows an advantageous development of the driver's seat according to the invention with reference to FIG. 1.

[0062] Additional protective sheets SCHB are provided to protect the compressed air hose and its fastenings against damage.
