A passenger door arrangement for an aircraft segment, which arrangement comprises a passenger door, which is configured to assume a raised state and a lowered state, and a “girt bar,” for arming and disarming an escape slide, the girt bar not altering its position relative to the passenger door in the transition from disarming to arming, when the passenger door is in the lowered state. Additionally an aircraft segment, which comprises the passenger door portion and a fuselage portion, an external engagement arrangement being fixed to the fuselage portion.

An actuating system for an actuatable door and to an actuatable door having such an actuating system. The actuating system comprises first and second rotatable latching shafts, a coupling link, first and second pivotable mechanical transmission elements that are mounted onto first and second rotatable latching shafts, respectively, and first and second latching members. First and second latching members are non-rotatably mounted to the second rotatable latching shaft and adapted for latching the actuatable door in a closed position. A first rotation of the first rotatable latching shaft results in pivoting of the first and second mechanical transmission elements and a second rotation of the second rotatable latching shaft, which causes a third rotation of first and second latching members.

A door system for an aircraft includes a door frame defining a door opening with a first perimeter strut and a second perimeter strut spaced apart from the first perimeter strut, at least one first frame stopper attached to the first perimeter strut and at least one second frame stopper attached to the second perimeter strut. The frame stoppers each comprise a first contact portion projecting into the door opening and having a first toothing. The first toothings are each formed on an inner surface of the first abutment portion. Further, the door system comprises a door mounted movably relative to the door frame and disposed in the door opening in a closed state, and a number of door stoppers corresponding to the number of frame stoppers disposed on opposite sides of the door and connected to the door, each door stopper having a second abutment portion. The second abutment portion comprises a second toothing formed complementary to the first toothing. The first toothing of a respective frame stopper and the second toothing of a respective door stopper engage in each other in the closed state of the door.

An evacuation slide may comprise a sliding surface extending from a head end to a toe end of the evacuation slide. An extendable dropdown volume may be configured to increase a height of the sliding surface at the toe end of the evacuation slide. The extendable dropdown volume may be configured to remain in a stowed position at a first sill height and deploy at a second sill height greater than the first sill height.

Aircraft door seals, especially door seals for aircraft cargo doors, include individual door seal sections joined together by a lap joint assembly. The door seal sections may have abutted ends establishing a seal junction, and a lap joint junction seal assembly to sealingly join the abutted ends of the door seal sections, wherein the lap joint junction seal assembly includes (i) a lap joint member having a lap joint base and a lap joint shelf extending from the lap joint base and sealingly engaged with a lower surface of the door seal sections over the seal junction, and (ii) an interior support spigot inserted within the interior space of each of the door seal sections at the abutted ends thereof. Each of the door seal sections may be a hollow profiled door seal defining the interior space and formed of an elastomeric sealing material.

An actuating system for an actuatable door and to an actuatable door having such an actuating system are provided. The actuating system comprises first and second rotatable latching shafts, a coupling link, first and second pivotable mechanical transmission elements that are mounted onto first and second rotatable latching shafts, respectively, and first and second latching members. First and second latching members are non-rotatably mounted to the second rotatable latching shaft and adapted for latching the actuatable door in a closed position. A first rotation of the first rotatable latching shaft results in pivoting of the first and second mechanical transmission elements and a second rotation of the second rotatable latching shaft, which causes a third rotation of first and second latching members.

The invention relates to an opening system (10) for an auxiliary door (20) of an airplane in a fuselage (30), the door and the fuselage having skins in the extension of one another. In one exemplary embodiment, the system (10) includes a framing lintel (11) integrated into the fuselage, an upper beam (2S) of the door structure arranged opposite the lintel (11), and a set of three lever links (4A, 4B, 4C). Each link is connected, on the one hand, to the lintel (11) by a lever articulation (5a, 6a) fixed relative to the fuselage (30) and, on the other hand, to the upper beam (2S) by a lever articulation (5b, 6b) mobile with the door (20), the articulations (5a, 5b; 6a, 6b) being connected respectively to the lintel (11) and to the upper beam (2S) by fittings (41, 43; 42, 44). The set of links includes two types of link mounted alternately, in which the mobile articulation (5b, 6b) remains positioned respectively close to the fuselage skin (30) and further from this skin (30), the articulations (5a, 5b; 6a, 6b) of two adjacent levers (4A, 4B; 4B, 4C) forming an evolving quadrilateral.

An actuating system for an actuatable door and to an actuatable door having such an actuating system. The actuating system comprises a rotatable latching shaft, a rotatable locking shaft, a latching device, comprising a latch, and a locking device. The latch is adapted to maintain the actuatable door in a closed position. The locking device comprises a locking cam, that is mounted to the locking shaft and that is adapted to engage with the latch in a closed and latched position, and a latch securing lever, that is driven by the locking cam and that is adapted to engage with the latch to maintain the latch in a closed and secured position.

A joining structure for two door members forming a door member for entrance opening and closing of an aircraft lavatory unit is configured so that a pair of brackets provided on the pair of door members are joined swingably by a bracket joining shaft; and one ends of a pair of covers are joined to the pair of brackets by bracket cover joining shafts, and the other ends of the pair of covers are joined swingably by a cover joining shaft, at a section farther away from the lavatory than the bracket joining shaft.

In an example, a seating system includes a seat comprising a chamber, a wall structure adjacent to the seat and defining a compartment, a door insert configured to move within the compartment between a starting position and a retracted position, wherein in the starting position, the door is adjacent to the seat and blocks access to the compartment, and in the retracted position, the door is retracted into the wall structure and provides access to the compartment, a closed channel extending from the chamber and operably connected to the door, and a piston operably coupled to the seat and positioned within the chamber, wherein when a load is applied to the seat, the piston is compressed, moving the door from the starting position to the retracted position, and when the load is removed, the piston is decompressed, causing the door to move from the retracted position to the starting position.
