Abstract

A truck cabin comprises a driver's seat, a bunk, and a frame, the frame comprising a rear structure delimiting the rear of the cabin along a longitudinal axis of the cabin. The bunk has the shape of a rectangular cuboid, with two parallel lateral faces, a front face, a rear face parallel to the front face, a lower face, and an upper face parallel to the lower face. The bunk is located between the driver's seat and the rear structure and extends along a transversal axis of the cabin, alongside the rear structure. The bunk is rotatable between a horizontal position, in which the upper face is horizontal and oriented upwardly, and a vertical position, in which the upper face is vertical. In the vertical position, the lower face of the bunk is oriented towards the rear structure and the upper face is oriented towards the driver's seat.

First claim

The invention claimed is:

1 . A truck cabin comprising a driver's seat, a bunk, and a frame, the frame comprising a rear structure delimiting the rear of the cabin along a longitudinal axis of the cabin, wherein:
the bunk has the shape of a rectangular cuboid, with two parallel lateral faces, a front face, a rear face parallel to the front face, a lower face, and an upper face parallel to the lower face and which is a bedding face; the bunk is located between the driver's seat and the rear structure, along the longitudinal axis, and extends along a transversal axis of the cabin, alongside the rear structure; the bunk is rotatable between a horizontal position, in which the upper face is horizontal and oriented upwardly, and a vertical position, in which the upper face is vertical; and in the vertical position, the lower face of the bunk is oriented towards the rear structure and the upper face is oriented towards the driver's seat, wherein the frame comprises:
two horizontal rails located on either side of the bunk along the transversal axis and extending each along a horizontal axis parallel to the longitudinal axis, and
at least one vertical rail, extending parallel to a vertical axis perpendicular to the longitudinal axis and to the transversal axis;
wherein the bunk is connected to the horizontal rails by two horizontal connectors, each of the two horizontal connectors allowing:
pivoting of the bunk around a first pivoting axis parallel to the transversal axis, the first pivoting axis being shared by the two horizontal connectors; and
sliding of the bunk along one of the two the horizontal rails;
wherein the bunk is connected to the at least one vertical rail by a vertical connector allowing:
pivoting of the bunk around a second pivoting axis parallel to the transversal axis; and
sliding of the bunk along the at least one vertical rail,
wherein the vertical connector comprises:
a bunk pin, connected to the bunk so as to be able to pivot around the second pivoting axis;
a rail pin, connected to one of the vertical rails so as to be able to pivot around a third pivoting axis parallel to the transversal axis and to slide along the at least one vertical rail; and
a guide link rigidly connecting the bunk pin to the rail pin so that the second pivoting axis and the third pivoting axis are offset from each other.

2 . The truck cabin of claim 1 , wherein, during the rotation of the bunk from the horizontal position to the vertical position, the rear face of the bunk is moving upwardly.

3 . The truck cabin of claim 1 , wherein an offset distance between the second pivoting axis and the third pivoting axis, measured perpendicular to the transversal axis, is comprised between 100 mm and 300 mm.

4 . The truck cabin of claim 3 , wherein an offset distance between the second pivoting axis and the third pivoting axis, measured perpendicular to the transversal axis, is equal to 200 mm.

5 . The truck cabin of claim 1 , wherein the vertical rail is located on the rear structure and wherein the vertical connector comprises a bracket fixed on the bunk and a slider pivotally attached with the bracket and sliding along the vertical rail.

6 . The truck cabin of claim 1 , wherein the horizontal connectors are located, along the longitudinal axis, on a frontal portion of the bunk and wherein, during the rotation of the bunk from the horizontal position to the vertical position, the front face is stationary along the vertical axis.

7 . The truck cabin of claim 1 , wherein the horizontal connectors are located, along the longitudinal axis, in a middle portion of the bunk and wherein, during the rotation of the bunk from the horizontal position to the vertical position, the front face is moving along the vertical axis downwardly.

8 . The truck cabin of claim 1 , wherein the truck cabin comprises a locking mechanism to secure the bunk in the horizontal position and to secure the bunk in the vertical position.

9 . The truck cabin of claim 8 , wherein the locking mechanism comprises:
a striker, fixed on the rear structure; two latches, fixed on the bunk; a rear latch being located, along the longitudinal axis and when the bunk is in the horizontal position, in a rear portion of the bunk to cooperate with the striker for locking the bunk in the horizontal position; and a front latch being located, along the longitudinal axis and when the bunk is in the horizontal position, in a frontal portion of the bunk to cooperate with the striker for locking the bunk in the vertical position.

10 . The truck cabin of claim 8 , wherein the locking mechanism comprises a release button, configured to unlock the locking mechanism.

11 . The truck cabin of claim 1 , wherein the rotation of the bunk is driven by at least one motor.

12 . The truck cabin of claim 11 , wherein the at least one motor is an electric motor.

13 . The truck cabin of claim 1 , wherein the rotation of the bunk is driven by a user pushing or pulling on the bunk along the longitudinal axis.
