CLAIMS

1 . A door system for a vehicle, the door system comprising:

a first door configured to move between a closed position, in which it covers at least a portion of an opening in a body of a vehicle, and an open position allowing access through the opening into a cabin of the vehicle;

a first barrier member moveable between a retracted position and a barrier position where it is configured to resist entry into the cabin of objects impacting against the first door; and

a control system configured to receive a sensor signal indicative of an impact and/or an expected impact on the first door, and to cause an actuator to move the first barrier member to the barrier position in dependence on receiving the sensor signal.

2. A door system according to claim 1 , wherein the actuator comprises a pyrotechnic device operable to cause movement of the first barrier member from the retracted position to the barrier position.

3. A door system according to claim 1 or claim 2, wherein the actuator comprises a spring configured to be loaded when the barrier member is in the retracted position, and the first barrier member is moveable from its retracted position to its barrier position by releasing energy stored in the spring.

4. A door system according to claim 1 or claim 2, wherein the actuator comprises a pneumatic cylinder arranged to be actuated by a compressed gas.

5. A door system according to any one of claims 1 to 4, wherein the first barrier member comprises a first portion and a second portion, the first barrier member being moveable between the retracted position in which the first portion and the second portion are both disposed above, or both disposed below, a floor level of the cabin, and the barrier position in which the first portion resides below the floor level and the second portion extends up to an elevated level, above the floor level.

6. A door system according to claim 5, wherein the first door comprises an outer panel and an inner panel, and, in the barrier position, the second portion is disposed between the inner panel and the outer panel.

7. A door system according to claim 5 or claim 6, wherein the first door has a base panel extending between a lower end of the inner panel and the outer panel, and the base panel is configured to rupture under pressure from the first barrier member when it is moved from the retracted position to the barrier position.

8. A door system according to any one of claims 5 to 7, wherein the cabin has a floor comprising a cover panel, and the cover panel is configured to rupture under pressure from the first barrier member when it is moved from the retracted position to the barrier position.

9. A door system according to any one of claims 5 to 8, wherein the first door comprises a crosspiece extending across the width of the first door, and in the barrier position the first barrier member is configured to provide support to the crosspiece to resist lateral movement of the crosspiece into the cabin.

10. A door system according to claim 9, wherein the crosspiece comprises a rail, and the first door is moveable between the closed position and the open position by the rail sliding on a guiding device.

1 1 . A door system according to any one of claims 5 to 10, wherein, in the retracted position, the first portion and the second portion are both positioned below the floor level and the first portion is retained within a housing that is rigidly attached to the body of the vehicle.

12. A door system according to any one of claims 5 to 10, wherein, in the retracted position, the first portion and the second portion are both positioned above the floor level and the second portion is retained within a housing that is rigidly attached to the first door.

13. A door system according to any one of claims 1 to 12, wherein the first barrier member is configured to move linearly between the retracted position and the barrier position.

14. A door system according to any one of claims 1 to 12, wherein the first barrier member is configured to rotate between the retracted position and the barrier position.

15. A door system according to any one of claims 1 to 14, wherein the sensor signal is received from a sensor configured to detect an impact on the first door.

16. A door system according to any one of claims 1 to 15, wherein the sensor signal is received from a sensor configured to detect movement of objects external to the vehicle.

17. A door system according to any one of claims 1 to 16, wherein:

the first door is supported at a first side of the opening by a first mechanism that enables the first door to move between the open position and the closed position;

the door system comprises a second door supported by a second mechanism at a second side of the opening, opposite to the first side, the second mechanism being configured to enable the second door to move between a closed position, in which it covers a portion of the opening in the body of the vehicle, and an open position allowing access through the opening into the cabin of the vehicle.

18. A door system according to claim 17, wherein, in the barrier position, the first barrier member is configured to resist entry into the cabin of objects impacting against the second door.

19. A door system according to claim 17 or claim 18, wherein:

the first door comprises a first crosspiece extending across the width of the first door; the second door comprises a second crosspiece extending across the width of the second door;

when the first door and the second door are in closed positions, a first end portion of the first crosspiece is aligned with a first end portion of the second crosspiece, and in the barrier position the first barrier member extends along the first end portions of the first crosspiece and the second crosspiece to resist external forces acting to misalign the first end portions.

20. A door system according to claim 19, wherein:

the first crosspiece comprises a first rail for enabling the first door to slide; and the second crosspiece comprises a second rail for enabling the second door to slide.

21 . A door system according to any one of claims 17 to 20, wherein the door system comprises a second barrier member moveable between a retracted position and a barrier position at which the second barrier member is configured to resist entry into the cabin of objects impacting against the second door.

22. A vehicle comprising a cabin having an opening to enable access into the cabin and a door system according to any one of the previous claims.

23. A method of providing a barrier to entry into a cabin in a body of a vehicle, the method comprising:

receiving a sensor signal indicative of an impact and/or an expected impact on a first door that covers an opening into the cabin of the vehicle; and

in dependence on receiving the sensor signal, providing an output signal to an actuator to cause the actuator to move a first barrier member from a retracted position to a barrier position where the first barrier member is configured to resist entry into the cabin of objects impacting against the first door.

24. A control system comprising at least one electronic processor having an electrical input for receiving the sensor signal and at least one electronic memory device electrically coupled to the electronic processor and having instructions stored therein, wherein the at least one processor is configured to access the at least one memory device and execute the instructions stored therein such that it is operable to perform the method of claim 23.

25. A non-transitory computer readable medium comprising computer readable instructions that, when executed by a processor, cause performance of the method of claim

23.
