Abstract

A cab for a tractor vehicle is provided with side spoilers that form extensions of the side walls of the cab in a backward direction and that can pivot between a backward-directed position and a sideways-directed position in order to give access to the chassis space behind the cab. A step arrangement is mounted on the inside of one side spoiler in such a way that it can be moved between a raised position, in which it is concealed behind the side spoiler, when this is in its backward-directed position, and a lowered position, in which it has a part with steps located below the lower edge of the side spoiler.

Claims (15)

1. A cab for a motor-driven tractor vehicle, comprising a body that has a rear body wall and side walls that are provided with side panels that form an extension of at least a part of each side wall in a backward direction to a plane at a distance from the rear body wall and that are arranged to bridge an air space between the rear body wall and a front wall of a connected trailer in order to deflect wind from the space between the rear body wall of the cab and the front wall of the trailer while the vehicle is being driven, with at least the front edge of one side panel being attached to the rear edge of the associated side wall in such a way that it can pivot, in order to enable it to be swung between a backward-directed position and a sideways-directed position, wherein, the pivoting side panel has a step arrangement on a side that faces inwards towards the space when in the backward-directed position, which step arrangement can move between an upper storage position, in which it is at least substantially concealed behind the side panel, and an in-use position, in which it has a part with steps located below a lower edge of the side panel.

2. The cab as claimed in claim 1 , wherein when the step arrangement is in its in-use position, the part has at least two steps located below the lower edge of the side panel.

3. The cab as claimed in claim 1 , wherein the step arrangement has support legs that rest against the ground on which the vehicle is disposed when the step arrangement is in its in-use position.

4. The cab as claimed in claim 1 , wherein the steps of the step arrangement are attached to vertical upright elements that are arranged a distance apart, the upright elements being mounted in such a way that they can move in vertical tracks that are attached to the side panel.

5. The cab as claimed in claim 1 , wherein the step arrangement is supported between two handrails that are attached to the side panel.

6. The cab as claimed in claim 2 , wherein the step arrangement has support legs that rest against the ground on which the vehicle is disposed when the step arrangement is in its in-use position.

7. The cab as claimed in claim 2 , wherein the steps of the step arrangement are attached to vertical upright elements that are arranged a distance apart, the upright elements being mounted in such a way that they can move in vertical tracks that are attached to the side panel.

8. The cab as claimed in claim 2 , wherein the step arrangement is supported between two handrails that are attached to the side panel.

9. The cab as claimed in claim 6 , wherein the steps of the step arrangement are attached to vertical upright elements that are arranged a distance apart, the upright elements being mounted in such a way that they can move in vertical tracks that are attached to the side panel.

10. The cab as claimed in claim 7 , wherein the step arrangement is supported between two handrails that are attached to the side panel.

11. The cab as claimed in claim 9 , wherein the step arrangement is supported between two handrails that are attached to the side panel.

12. The cab as claimed in claim 3 , wherein the steps of the step arrangement are attached to vertical upright elements that are arranged a distance apart, the upright elements being mounted in such a way that they can move in vertical tracks that are attached to the side panel.

13. The cab as claimed in claim 3 , wherein the step arrangement is supported between two handrails that are attached to the side panel.

14. The cab as claimed in claim 12 , wherein the step arrangement is supported between two handrails that are attached to the side panel.
