An aircraft 1 comprises a walkway 11 moveable between a stowed position and a deployed position. The aircraft may be arranged such that the walkway, in the deployed position, defines a path, at least a portion of which extends from the fuselage at an angle, when viewed from above, of less than 90 degrees to the longitudinal axis of the aircraft. The walkway 11, in the stowed position, may be located at an angle, when viewed from above, of less than 80 degrees to the longitudinal axis of the aircraft. The opening 9 may be located in a region extending from 20% to 80% of the total cabin length. The walkway may be further moveable to a second deployed position. A longitudinal portion of the walkway 13, in the first deployed position, may define a stepped surface having a first step height, whereas that longitudinal portion of the walkway 13, in the second deployed position, may define either (a) a substantially even surface, or (b) a stepped surface having a second step height, the second step height being less than the first step height. |

Attachment bolts and tensioned support systems (e.g., aircraft access systems) are set forth herein. According to one embodiment, an attachment bolt for use in a tensioned support system includes a head portion and a shaft portion extending from the head portion. The head portion has an end face, and the shaft portion has at least one thread and a tip distal to the head portion. A cavity extends entirely through the head and shaft portions and has a linearly extruded segment, an extended diameter at the end face, and an enlarged diameter at the tip. The extended diameter is larger than a diameter of the linearly extruded segment, and the enlarged diameter is larger than the diameter of the linearly extruded segment. |

Boarding ramp device for aircraft |

A foldable boarding ramp is operatively connected to a door opening provided in a body and is selectively extendable to the ground. The foldable boarding ramp is stored in a folded state inside a fairing covering a connecting portion between the body and a main wing. Thus, a reduction in the space of a passenger compartment and a cargo compartment due to the storage of the folded boarding ramp is prevented. In addition, an increase in air resistance can be suppressed without providing a dedicated fairing for covering the boarding ramp. Further, an interlocking member connects together a door for opening and closing the door opening and the boarding ramp when the door is opened. The boarding ramp may be automatically deployed to improve convenience. |

This collapsible staircase is provided with a set of flat parts (6) each intended to function as steps.Each flat part (6) can be moved between a first position and a second position. All the flat parts (6) are substantially coplanar when they are in their first position, and are disposed one above the other and at a distance from one another when they are all in their second position.Advantageously, a retractable holding handle (44) is also provided and driven in movement together with the flat parts (6). |

Thomas Gray Wilson |
A stair construction for a vehicle is attached to the vehicle at a position below a vehicle door and supports the weight of users entering and exiting the vehicle. In the event of forces that tend to bend or push the stairs upward into interference with the door, the stairs will fracture and break or generally predictably deform so that they do not interfere with the door. |

The present invention has as an object a foldable staircase for vehicles, for examples in airplane, which, once folded, is housed in a compartment provided in the fuselage.This staircase comprises:a carriage (4) slidably mounted in the compartment (1) which carriage receives, in an overhanging manner, a foldable staircase structure (5) which, when it is housed in the compartment, is folded and extends toward the opening (3) of this latter,a motor mechanism (6) either for driving the carriage (4) toward the opening (3) and extracting the structure from the compartment (1) outside of which it will be deployed, or for restoring the structure into the compartment after this latter has been folded and conducted at the time of folding into the axis of the compartment,and motor means (7) for unfolding or re-folding, along a vertical plane, the structure (5) when this latter is outside of the compartment (1). |

Upper and lower sectional doors of rectangular configuration are mounted within an aircraft fuselage door frame and hinged for pivoting about horizontal axes at the upper and lower horizontal edges of respective door sections. A step is mounted to the interior of the lower door for pivoting along one horizontal edge about a horizontal axis between a first position with the step flush with the door interior and a second position projecting generally at right angles thereto. A plurality of laterally slidable latch pins fixed to the lower door section along vertical side edges are projectable into holes within the fuselage doorframe through a linkage system coupled to a shaft pivotably mounting the step to the door. The latch pins are projected to latching position when the step is folded flush to the door and retracted to unlatched position by manual movement of the step to its projected position prior to opening the lower door. |

Irwin G. Baker |
An aircraft in which the fuselage and wings are configured in a blended wing design has a door opening in the fuselage adjacent the wing and a door assembly for closing the door opening. The door assembly includes a door having an exterior panel that conforms to the shape of the aircraft at the location of the door opening when the door is closed and having an interior structure configured in a series of steps. The door is movable between a closed position in which an upper edge of the door panel is adjacent an upper edge of the door opening and an open position in which the door panel lies substantially within the wing and in which the upper edge of the door panel is adjacent an upper surface of the wing and spaced from the fuselage. When the door is in the open position, the steps form a stairway leading from the fuselage up and out of the aircraft to the upper surface of the wing. Preferably, the door assembly also includes a movable wing panel which is slaved to the door such that, as the door is moved from the closed to the open position, the wing panel moves to uncover an opening in the wing upper surface through which the door passes to reach its open position. |
