Abstract

A vehicle with a fairing and a sliding door that is glidingly mounted to the vehicle, wherein the sliding door is associated with a foldable fairing integrated footstep unit, and wherein the foldable fairing integrated footstep unit comprises: an outer shell that is integrated into the fairing of the vehicle, the outer shell comprising an exterior surface that creates in closed state of the foldable fairing integrated footstep unit an at least approximately continuous aerodynamic surface with the fairing.

First claim

What is claimed is:

1. A vehicle with a fairing and a sliding door that is glidingly mounted to the vehicle, wherein the sliding door is associated with a foldable fairing integrated footstep unit, and wherein the foldable fairing integrated footstep unit comprises:
an outer shell that is integrated into the fairing of the vehicle, the outer shell comprising an exterior surface that creates in closed state of the foldable fairing integrated footstep unit an aerodynamic surface with the fairing,
wherein an unfolding and folding unit connects the outer shell to the vehicle, the unfolding and folding unit comprising:
a sliding mechanism that is adapted for being engaged by the sliding door at least during an opening gliding movement and a closing gliding movement of the sliding door, and
a guiding link that connects the outer shell to the sliding mechanism;
the unfolding and folding unit being provided for unfolding the foldable fairing integrated footstep unit into an opened state during the opening gliding movement of the sliding door and for folding the foldable fairing integrated footstep unit into the closed state during the closing gliding movement of the sliding door.

2. The vehicle of claim 1 , wherein a housing is provided, the housing being adapted for accommodating the foldable fairing integrated footstep unit in the closed state such that the exterior surface of the outer shell creates the continuous aerodynamic surface with the fairing.

3. The vehicle of claim 1 , wherein a door rail is provided, and wherein the sliding door and the sliding mechanism are glidingly mounted to the door rail.

4. The vehicle of claim 3 , wherein the sliding door comprises at least one sliding mechanism support that is adapted for engaging the sliding mechanism at least during the opening gliding movement and the closing gliding movement of the sliding door.

5. The vehicle of claim 1 , wherein the guiding link comprises at least one rigid strut.

6. The vehicle of claim 5 , wherein the unfolding and folding unit further comprises:
at least two couplers, wherein a first coupler is provided for rotatably coupling the at least one rigid strut to the outer shell, and wherein a second coupler is provided for rotatably coupling the at least one rigid strut to the sliding mechanism.

7. The vehicle of claim 1 , wherein the foldable fairing integrated footstep unit further comprises:
at least one slider link that is adapted for limiting an opening rotation of the outer shell during the opening gliding movement of the sliding door.

8. The vehicle of claim 7 , wherein at least one bracket is provided, the at least one bracket being rigidly attached to the vehicle, and wherein the at least one slider link is rotatably mounted to the at least one bracket and comprises a pin guide that glidingly accommodates an associated slide pin provided at the outer shell.

9. The vehicle of claim 1 , wherein the foldable fairing integrated footstep unit further comprises:
at least one cable connection that is adapted for limiting an opening rotation of the outer shell during the opening gliding movement of the sliding door.

10. The vehicle of claim 9 , wherein the at least one cable connection comprises a cable that is attached to the outer shell and connected to a cable socket that is accommodated in the vehicle for retracting the cable during the closing gliding movement of the sliding door.

11. The vehicle of claim 1 , wherein the foldable fairing integrated footstep unit further comprises:
at least one double arm connection that is adapted for limiting an opening rotation of the outer shell during the opening gliding movement of the sliding door.

12. The vehicle of claim 11 , wherein at least one bracket is provided, the at least one bracket being rigidly attached to the vehicle, wherein the at least one double arm connection comprises a first arm that is rotatably mounted to the at least one bracket and a second arm that glidingly accommodates an associated slide pin provided at the outer shell, and wherein the first arm is rotatably mounted to the second arm.

13. The vehicle of claim 1 , wherein the foldable fairing integrated footstep unit further comprises:
an extendible stepping element that is accommodated in the outer shell in the closed state of the foldable fairing integrated footstep unit and protruding from the outer shell in opened state of the foldable fairing integrated footstep unit.

14. The vehicle of claim 13 , wherein the foldable fairing integrated footstep unit further comprises:
a spring-loaded link that is provided for moving the extendible stepping element during the opening gliding movement of the sliding door such that the extendible stepping element protrudes from the outer shell in opened state of the foldable fairing integrated footstep unit.

15. A vehicle with a fairing and a sliding door glidingly mounted to the vehicle, wherein the sliding door is associated with a foldable fairing integrated footstep unit, and wherein the foldable fairing integrated footstep unit comprises:
an outer shell comprising an exterior surface that creates in a closed state of the foldable fairing integrated footstep unit an aerodynamic surface with the fairing,
wherein a guiding unit connects the outer shell to the vehicle, the guiding unit comprising:
a slider adapted for being engaged by the sliding door during an opening gliding movement and a closing gliding movement of the sliding door, and
a guiding link connecting the outer shell to the slider;
the guiding unit provided for unfolding the foldable fairing integrated footstep unit into an opened state during an opening gliding movement of the sliding door and for folding the foldable fairing integrated footstep unit into the closed state during a closing gliding movement of the sliding door.

16. The vehicle of claim 15 , further comprising a housing adapted for accommodating the foldable fairing integrated footstep unit in the closed state such that the exterior surface of the outer shell creates the continuous aerodynamic surface with the fairing.

17. The vehicle of claim 1 , further comprising a door rail, the sliding door and the slider are glidingly mounted to the door rail, the sliding door comprising at least one sliding support adapted for engaging the slider during the opening gliding movement and the closing gliding movement of the sliding door.

18. The vehicle of claim 1 , wherein the guiding link comprises a rigid strut, and wherein the unfolding and folding unit further comprises:
at least two couplers, wherein a first coupler rotatably coupling the rigid strut to the outer shell, and wherein a second coupler rotatably coupling the rigid strut to the slider.

19. A rotary wing aircraft with a fairing and a sliding door glidingly mounted to the rotary wing aircraft, the sliding door associated with a foldable fairing integrated footstep unit, the foldable fairing integrated footstep unit comprising:
an outer shell comprising an exterior surface capable of forming in a closed state of the foldable fairing integrated footstep unit an aerodynamic surface with the fairing,
a guiding unit connecting the outer shell to the rotary wing aircraft, the guiding unit comprising:
a slider adapted for being engaged by the sliding door during an opening gliding movement and a closing gliding movement of the sliding door, and
a guide connecting the outer shell to the slider;
