Abstract

A driver cabin for an urban railway vehicle, the driver cabin extending in a longitudinal driving direction and including: a cabin chassis including at least one main shock-absorbing area having a longitudinal extend defined between a front plane oriented transversally to the longitudinal driving direction and a rear plane oriented transversally to the longitudinal driving direction, the main shock-absorbing area being able to deform in case of a shock between an initial state and a shock-absorbed state, so that in the shock-absorbed state the longitudinal extend of the main shock-absorbing area is reduced about a predefined compression distance; an electrical equipment compartment storing at least one stiff electrical element carrying electronic components. The electrical equipment compartment is located inside the main shock-absorbing area.

First claim

What is claimed is:

1. A driver cabin for an urban railway vehicle, said driver cabin extending in a longitudinal driving direction and comprising:
a cabin chassis including at least one main shock-absorbing area having a longitudinal extent defined between a front plane oriented transversally to the longitudinal driving direction and a rear plane oriented transversally to the longitudinal driving direction, the main shock-absorbing area configured to deform in case of a shock between an initial state and a shock-absorbed state, so that in the shock-absorbed state the longitudinal extent of the main shock-absorbing area is reduced along a predefined compression distance;
an electrical equipment compartment storing at least one stiff electrical element carrying electronic components, the at least one stiff electrical element having a force for deformation in a direction parallel to the longitudinal driving direction exceeding 10% of a deformation force necessary to deform the main shock-absorbing area;
wherein:
the electrical equipment compartment is located inside the main shock-absorbing area,
the at least one stiff electrical element is substantially planar and substantially oriented in a transverse direction relative to the longitudinal driving direction,
the electrical equipment compartment comprises at least one deformation space extending in the longitudinal driving direction along an initial length, the sum of the initial lengths of the at least one deformation space being greater than the predefined compression distance.

2. The driver cabin of claim 1 , wherein said at least one deformation space only contains elements configured to deform simultaneously with the main shock-absorbing area when receiving a shock or is devoid of such elements.

3. The driver cabin of claim 1 , wherein the cabin chassis includes at least a first side section and a second side section, symmetrically arranged around the longitudinal driving direction, the first and second side sections comprise each at least one main shock-absorbing organ symmetrically arranged around the longitudinal driving direction, the main shock-absorbing organs defining the main shock-absorbing area.

4. The driver cabin of claim 3 , wherein the at least one stiff electrical element comprises at least one first stiff electrical element carried by the main shock-absorbing organ of the first or second side section.

5. The driver cabin of claim 1 , wherein the cabin chassis includes a rear section extending parallel to the rear plane, and wherein the at least one stiff electrical element comprises at least one second stiff electrical element carried by the rear section.

6. The driver cabin of claim 1 , wherein the at least one stiff electrical element comprises a first and a second stiff electrical elements, distant from each other of approximately the compression distance.

7. The driver cabin of claim 1 , wherein the electrical equipment compartment comprises flexible cover panels, the flexible cover panels being configured to deform simultaneously with the main shock-absorbing area when receiving a shock.

8. The driver cabin of claim 7 , wherein each cover panel is made out of aluminum and has a thickness about 0.6 mm.

9. An urban railway vehicle comprising a driver cabin according to claim 1 .

10. The driver cabin of claim 1 , wherein the elements of the at least one deformation space configured to deform simultaneously with the main shock-absorbing area when receiving a shock are frangible elements and/or flexible elements configured to deform in response to the shock.

11. The driver cabin of claim 1 , wherein the cabin chassis further includes a secondary area disposed longitudinally adjacent the at least one main shock-absorbing area.

12. The driver cabin of claim 1 , wherein the cabin chassis further includes a secondary area disposed adjacent the at least one main shock-absorbing area, the secondary area and the at least one main shock-absorbing area each extending along a chassis longitudinal extent of the cabin chassis, wherein the longitudinal extent of the at least one main shock-absorbing area extends generally parallel to the chassis longitudinal extent, and wherein, in case of a shock, the cabin chassis is configured such that a majority of reduction of the cabin chassis along the chassis longitudinal extent is provided by the main shock-absorbing area being configured to be reduced along its longitudinal extent.
