Abstract

An evacuation slide comprises a sliding face having a top end portion adapted to be positioned adjacent to an exit of a region to be evacuated, and a bottom end portion adapted to be positioned adjacent to an escape route leading away from, and at a lower height, than the region. The sliding face, at the top end portion, comprises a flat porch section connected to an inclined section of the sliding face via a transition section. The sliding face has at least one of a first guidance marking placed in the flat porch section and having a shape and orientation adapted indicate a predefined evacuation direction in the inclined section of the sliding face and a second guidance marking placed in the transition section and having a shape and orientation adapted to indicate a separation between the flat porch section and the inclined section.

First claim

The invention claimed is:

1. An evacuation slide comprising:
a sliding face having a top end portion adapted to be positioned adjacent to an exit of a region to be evacuated, and a bottom end portion adapted to be positioned adjacent to an escape route leading away from the region to be evacuated and being arranged at a lower height than the region to be evacuated,
wherein the sliding face, in the region of its top end portion, comprises a flat porch section which is connected to an inclined section of the sliding face via a transition section,
wherein the sliding face is provided with a first guidance marking placed in the flat porch section of the sliding face and having a shape and orientation adapted to indicate a predefined evacuation direction in the inclined section of the sliding face, wherein a light signal generating device comprising a first lighting element is adapted to irradiate a light signal downward onto the first guidance marking, wherein the first lighting element is not located on a planar surface of the sliding face,
wherein the first lighting element is fixed to a lateral limitation element extending from the sliding face along a lateral edge thereof,
wherein the first guidance marking comprises a fluorescent material which is adapted to emit fluorescent radiation.

2. The evacuation slide according to claim 1 , wherein the first guidance marking has the shape of an arrow.

3. The evacuation slide according to claim 1 , wherein a lateral edge of the flat porch section and a corresponding adjacent lateral edge of the inclined section of the sliding face define an angle of less than 180° such that projections of the flat porch section and the inclined section of the sliding face in a common plane are arranged in a slanted manner relative to each other.

4. The evacuation slide according to claim 3 , wherein an edge of the flat porch section which faces away from the transition section is designed in the form of a straight edge adapted to be positioned adjacent to the exit of the region to be evacuated, and wherein an edge of the flat porch section which faces the transition section extends in a further slanted manner relative to the edge of the flat porch section which faces away from the transition section.

5. The evacuation slide according to claim 4 , wherein the first guidance marking, in order to indicate the predefined evacuation direction in the inclined section of the sliding face, extends across the flat porch at an angle less than 90° relative to the edge of the flat porch section which faces away from the transition section.

6. The evacuation slide according to claim 3 , wherein the first guidance marking, in order to indicate the predefined evacuation direction in the inclined section of the sliding face, extends across the flat porch section at an angle less than 90° relative to the edge of the flat porch section which faces away from the transition section.

7. The evacuation slide according to claim 1 , wherein the sliding face is provided with a second guidance marking placed in the transition section of the sliding face.

8. The evacuation slide according to claim 7 , wherein a lateral edge of the flat porch section and a corresponding adjacent lateral edge of the inclined section of the sliding face define an angle of less than 180° such that projections of the flat porch section and the inclined section of the sliding face in a common plane are arranged in a slanted manner relative to each other,
wherein an edge of the flat porch section which faces away from the transition section is designed in the form of a straight edge adapted to be positioned adjacent to the exit of the region to be evacuated, and wherein an edge of the flat porch section which faces the transition section extends in a further slanted manner relative to the edge of the flat porch section which faces away from the transition section, and
wherein the second guidance marking, in order to indicate a separation between the flat porch section and the inclined section of the sliding face, extends along the edge of the flat porch section which faces the transition section at an angle less than 90° relative to the edge of the flat porch section which faces away from the transition section.

9. The evacuation slide according to claim 7 , wherein the second guidance marking comprises a further fluorescent material which is adapted to emit fluorescent radiation.

10. The evacuation slide according to claim 9 , wherein the light signal generating device is adapted to irradiate a light signal onto the second guidance marking which is suitable to cause the second guidance marking to emit fluorescent radiation.

11. The evacuation slide according to claim 10 , wherein the light signal generating device is adapted to irradiate UV-light onto the at least one of the first guidance marking and the second guidance marking.

12. The evacuation slide according to claim 10 , wherein the light signal generating device a second lighting element.

13. The evacuation slide according to claim 12 , wherein the second lighting element is arranged in a second lateral edge portion of the evacuation slide opposite the first lateral edge portion in the area of the flat porch section and is adapted to irradiate light in an irradiation direction directed towards a center portion of the flat porch section of the sliding face.

14. The evacuation slide according to claim 12 , wherein the second lighting element is fixed to the lateral limitation element extending from the sliding face.

15. The evacuation slide according to claim 14 , wherein at least one of the first lighting element and the second lighting element is fixed to a wall portion of the lateral limitation element which faces the center portion of the flat porch section of the sliding face.

16. The evacuation slide according to claim 1 , wherein the fluorescent material is adapted to emit fluorescent radiation when being irradiated with blue light.

17. The evacuation slide according to claim 1 , wherein the first lighting element is arranged in a first lateral edge portion of the evacuation slide in the area of the flat porch section and is adapted to irradiate light in an irradiation direction directed towards a center portion of the flat porch section of the sliding face.

18. An evacuation slide comprising:
a sliding face having a top end portion adapted to be positioned adjacent to an exit of a region to be evacuated, and a bottom end portion adapted to be positioned adjacent to an escape route leading away from the region to be evacuated and being arranged at a lower height than the region to be evacuated, wherein the sliding face, in the region of its top end portion, comprises a flat porch section which is connected to an inclined section of the sliding face via a transition section, and
wherein the sliding face is provided with a guidance marking placed in the transition section of the sliding face,
wherein the guidance marking is a scratch line extending across the sliding face, in the transition section thereof,
wherein the scratch line is a broken line composed of individual line elements arranged side by side in a direction substantially perpendicular to the predefined evacuation direction in the inclined section of the sliding face, and
wherein each individual line element extends in a direction substantially parallel to the predefined evacuation direction in the inclined section of the sliding face.

19. A vehicle comprising an evacuation slide comprising:
a sliding face having a top end portion adapted
