Description

Technical Field

[0001] This invention relates to a passenger door assembly for an aircraft section, particularly including, for example, a rescue slide actuation mechanism driven by a Bowden line, which non-movably transfers a main interface component, for example, in the form of a rescue slide bar, by means of the rotational movement of a safety pin or locking bolt. The invention also relates to an aircraft section equipped with such a passenger door assembly. Background Technology

[0002] When the passenger doors of an aircraft are closed, locked, and secured, the emergency slides can typically be manually pre-positioned from the inside via a selection lever mechanism located in the area inside the passenger door. When the emergency slide is connected to the emergency slide pole, the pole functions as the main interface section. In the pre-positioned state, the emergency slide pole engages with the passenger door and, for example, the fuselage section formed as a door frame section through its own movement. When the passenger door is subsequently opened in an emergency, the emergency slide pole is released from the passenger door by a lifting movement, while remaining engaged with the fuselage section. Thus, the emergency slide is reliably positioned within the aircraft structure.

[0003] In addition, during the raising of the passenger doors, a device on the fuselage side, using spring force, can move the frame of the emergency slide pole back to the closed position, thus preventing any possible inward movement of the emergency slide pole. Summary of the Invention

[0004] The purpose of this invention is to provide a passenger door assembly for an aircraft section and an aircraft section equipped with a simple and space-saving design for securing a life-saving slide.

[0005] This objective is achieved by the passenger door assembly of the present invention and the aircraft section of the present invention.

[0006] In a first aspect, a passenger door assembly with a passenger door is provided for an aircraft section. The passenger door is movable between an elevated position and a lowered position relative to a fuselage section receiving the passenger door. The fuselage section may be formed, for example, in the form of a door frame and have a door opening for receiving the passenger door. Furthermore, the passenger door assembly includes a rescue slide bar, i.e., a "restraint bar," for pre-positioning or de-positioning a rescue slide. The rescue slide bar can be connected to the passenger door and / or the fuselage section via a connecting assembly. Correspondingly, the rescue slide connected to the rescue slide bar can be selectively connected to the passenger door and / or the fuselage section by means of the connecting assembly.

[0007] The connecting assembly is configured to positionally hold the rescue slide pole relative to the passenger door in its lowered position when the rescue slide is in its pre-positioned state. In other words, in the passenger door assembly, the position of the rescue slide pole relative to the passenger door remains unchanged when the rescue slide transitions from the pre-positioned state (released) to the pre-positioned state (lowered).

[0008] The passenger door assembly eliminates the need for complex interfaces between the passenger door, the emergency slide bar, and the fuselage. Such complex interfaces could lead to overly difficult or complicated operations and disruptions during production and maintenance. In particular, it eliminates the complex movements caused by the transfer of the emergency slide bar between the passenger door and the emergency slide. Therefore, the emergency slide securing device in the passenger door assembly is lightweight, simple in design, and robust in terms of operation and tolerances.

[0009] Preferably, the connecting assembly is configured to connect the rescue slide arm to the passenger door in the pre-positioned state of the rescue slide. This reliably prevents unintentional release of the rescue slide when the passenger door is opened. Additionally or alternatively, the connecting assembly is configured to connect the rescue slide arm to the fuselage section in the pre-positioned state of the rescue slide. This ensures that the rescue slide can be reliably connected to the fuselage section in an emergency and can be used without restriction.

[0010] In a first configuration of the first aspect, the connecting assembly preferably includes a mechanism configured to releasably lock and secure the rescue slide bar to an external engagement device. Preferably, the external engagement device can be fastened to a fuselage section.

[0011] For example, the mechanism of the connecting assembly can be connected to the rescue slide bar in such a way that the mechanism does not change its position relative to the rescue slide bar. Additionally or alternatively, the mechanism is preferably configured to be secured to the passenger door in the raised state, before or during the transition from the pre-positioned release of the rescue slide to the pre-positioned lowered state of the passenger door. Furthermore, the mechanism can be configured to, preferably, be released from the passenger door in the raised state after the rescue slide has been pre-positioned.

[0012] In the second configuration of the first aspect, the passenger door assembly preferably further includes an operating member, which is connected at one end, for example via a Bowden line, to a selection lever mechanism located in a region inside the passenger door assembly, and at the other end to a connecting assembly, i.e., the mechanism of the connecting assembly, and the operating member is configured to activate and ensure the pre-positioning or de-positioning of the emergency slide. With the door assembly assembled in the aircraft section, the selection lever mechanism is accessible to users (e.g., flight attendants) residing in the aircraft cabin.

[0013] In the third configuration of the first aspect, the mechanism preferably comprises a closing bolt disposed at the end of the lifespan slide arm, the closing bolt being configured for rotational engagement with an external engagement device. The connecting assembly preferably includes an adjusting member fastened to the passenger door, the adjusting member being configured to: in the lowered state of the passenger door, place the external engagement device in a ready state for receiving rotational engagement with the closing bolt.

[0014] In a second aspect, an aircraft segment is provided, the aircraft segment including the aforementioned passenger door assembly and fuselage section, wherein the external coupling device is fixed at the fuselage section.

[0015] The passenger door section of the aircraft segment can be implemented according to the third configuration of the first aspect, wherein preferably:

[0016] • The external engagement device includes an elongated hole, and the sealing bolt includes at least two protrusions configured to rotate into the elongated hole during the transition from release to pre-position when the passenger door is in a lowered state; and / or

[0017] The external engagement device further includes a flipping element comprising a first end on one side of the lever arm and a second end on the other side of the lever arm, wherein the first end of the flipping element is arranged opposite to the adjusting member, wherein the second end of the flipping element extends into the elongated hole and is configured to reject a rotational engagement for receiving the closing bolt, and wherein, before the lifesaver slide transitions from a released pre-position to a pre-positioned position, when the passenger door is lowered, the adjusting member is configured to press the first end of the flipping element downwards, causing the second end of the flipping element to be raised, thereby creating a pre-positioned engagement for receiving the closing bolt; and / or

[0018] The second end of the flipping element also includes a recess that corresponds in shape to one of the protrusions of the sealing bolt, and the recess is configured to engage with one of the protrusions when the passenger door is lowered after the rescue slide transitions from release to pre-position, thereby securing the sealing bolt.

[0021] Figure 2 The AD demonstrates the four steps for pre-positioning a rescue slide. Figure 1 The application of the life-saving slide movement mechanism shown in the image is that the passenger door of the passenger door assembly is initially in the raised position. Detailed Implementation

[0022] In the following description, specific details are described for illustrative and not limiting purposes to ensure a basic understanding of the techniques described herein. Those skilled in the art will recognize that the technology can be implemented in other embodiments that differ from these specific details.

[0023] Figure 1 An aircraft segment 1 equipped with a passenger door assembly 10 is shown, wherein the external shape of both the passenger door assembly 10 and the aircraft segment 1 is shown only schematically. The passenger door assembly 10 includes a passenger door 11, also shown only schematically, configured to occupy an elevated and a lowered state. The passenger door 11 is movable between the elevated and lowered positions relative to the fuselage segment 2 of the aircraft segment 1 that receives the passenger door 11. This aircraft segment can be designed, for example, as a door frame with a door opening and... Figure 1 The image shown is also only schematic.

[0024] Furthermore, the passenger door assembly 10 includes a rescue slide rod 12 for pre-positioning or de-positioning the rescue slide 13. For this purpose, the rescue slide rod 12 serves as the main interface portion with... Figure 1 The rescue slide 13 is also only shown schematically in the diagram. The rescue slide bar 12 can be connected via... Figure 1 The connecting component 14, shown in detail, connects to the passenger door 11 and / or the fuselage section 2. Figure 1 The upper area shows the component on the passenger door side of the connecting assembly 14, that is, the component associated with the passenger door 11. Figure 1 The lower area shows the component on the fuselage section side of the connecting assembly 14, that is, the component associated with the fuselage section 2.

[0025] In the passenger door assembly 10, when the rescue slide 13 transitions from the released pre-position state to the lowered position of the passenger door 11, the position of the rescue slide rod 12 relative to the passenger door 11 remains unchanged. In other words, the rescue slide rod 12 is fixedly held relative to the lowered position of the passenger door 11 when the rescue slide 13 is in the pre-positioned state by means of the connecting assembly 14. As will be described in detail below, the connecting device 14 is provided for connecting the rescue slide rod 12 to the passenger door 11 in the released pre-positioned state of the rescue slide 13. In the pre-positioned state of the rescue slide 13, the connecting assembly 14, on the contrary, connects the rescue slide rod 12 to the fuselage section 2.

[0026] The connecting assembly 14 of the passenger door assembly 10 includes a mechanism 101b configured to releasably lock and secure the life slide pole 12 to an external engagement device 14b fastened to the fuselage section 2. It is important to emphasize that the mechanism 101b is part of the passenger door 11, and not part of the fuselage section 2, another part of the fuselage, or the cabin floor. The mechanism 101b is connected to the life slide pole 12 such that the mechanism 101b does not change its position relative to the life slide pole 12 (see reference). Figure 2 ).

[0027] When the passenger door 11 is in the raised position, the mechanism 101b is secured to the passenger door 11 before or during the transition of the emergency slide 13 from the released pre-position to the pre-position in the lowered position of the passenger door 11. However, after the emergency slide 13 is pre-positioned in the raised position of the passenger door 11, the mechanism 101b is set to release from the passenger door 11.

[0028] Furthermore, the passenger door assembly 10 includes an operating member 15, which is connected at one end to a selection lever mechanism 4 disposed in a region inside the passenger door assembly 10 via a Bowden line (not shown in the figure), and at the other end to a mechanism 101a of a connecting assembly 14 constituting a safety device for the life slide. When the selection lever mechanism 4 is operated, a rotational operating force is transmitted to the adjusting member 15 via the Bowden line, thereby triggering and ensuring the pre-positioning or de-positioning of the life slide 13.

[0029] In the embodiment of the passenger door assembly 10 shown in the figure, mechanism 101b is implemented in the form of a closing bolt 101b disposed at the end of the rescue slide bar 12. The closing bolt 101b includes two protrusions (or tenons) 1011b. The external engagement device 14b includes an elongated hole 142b, wherein the elongated hole 142b corresponds in size to the shape of the two protrusions 1011b as follows, such that the two protrusions 1011b can pass through the elongated hole 142b without collision. However, it is also possible, for example, to provide a corresponding recess in the elongated hole 142b, into which the protrusion 1101b can engage.

[0030] Furthermore, the passenger door side component of the connecting assembly 14 includes an adjusting member 111b fastened to the passenger door 11, which is formed as a roller. Conversely, the connecting assembly 14 (i.e., the external engagement device 14a) includes a flipping element 141b on the fuselage section side, the flipping element including a first end on one side of the lever arm and a second end on the other side of the lever arm. The first end of the flipping element 141b is arranged opposite to the adjusting member 111b (i.e., aligned during downward movement). However, the second end of the flipping element 141b extends into an elongated hole 142b. The flipping element 141b has a recess 1411b at its second end (see especially...). Figure 2 d, from the lower plan view A), the recess corresponds in shape to the protrusion 1101b of the closing bolt.

[0031] The following text refers to Figure 2 The function of the rescue slide movement mechanism shown in this article is explained in four steps, and in particular the function of the connecting component 14 for pre-positioning the rescue slide 13 in the raised state of the passenger door 11.

[0032] exist Figure 2 In the raised state of the passenger door 11 shown in figure a, before the rescue slide 13 transitions from the released position to the pre-positioned position, the rescue slide rod 12 is fastened to the passenger door 11 via a closing bolt connected to the operating member 15. Here, the closing bolt is arranged relative to the external engagement device 14b such that the protrusion 1101b provided at the closing bolt is aligned with the elongated hole 142b of the external engagement device 14. The fixing element 103 fastened to the passenger door 11 prevents movement of the rescue slide rod 12 in the y and z directions.

[0033] If now, such as Figure 2 As shown in Figure b, when the passenger door 11 is lowered relative to fuselage section 2, the mechanism 101b, implemented in the form of a sealing bolt, is rotatably engaged with the external engagement device 14b. That is, the sealing bolt is lowered into the elongated hole 142b, so that the protrusion 1101b formed at the sealing bolt is received in the elongated hole 142b. Furthermore, the adjusting member 111b presses down on the first end of the flipping element 141b, causing the second end of the flipping element 141b to rise. This creates a ready state for rotatably engaging the sealing bolt.

[0034] When the passenger door 11 is closed, locked, and secured, the rescue slide 13 can be manually pre-positioned from the inside via the selector lever mechanism 4. The required force is transmitted by the selector lever mechanism 4 to the lower interface area of ​​the rescue slide's movement mechanism via the Bowden line and the operating member 15. The pre-positioning of the rescue slide 13 is achieved, in particular, by rotating the operating member 15 90° about the longitudinal axis L of the mechanism 101b, which is formed in the form of a closed bolt, wherein the rotation of the operating member 15 is transmitted to the mechanism 101b, which is formed in the shape of a closed bolt, via the profile member 104. The profile member 104 includes a protrusion 105 formed at the closed bolt and a receiving seat 106 formed at the operating member 15 and complementary to the protrusion 105.

[0035] By rotating the closing bolt, the protrusion 1101b formed at the closing bolt is locked / interlocked relative to the external engagement device 14b, that is, one of these protrusions 1101b engages with the recess 1411b formed at the second end of the flipping element 141b (see...). Figure 2 c and d, from the lower plan view A). Thus, when the closing bolt has reached Figure 2 When position c is shown, the sealing bolt is secured and creates a rotational engagement with the elongated hole 142b.

[0036] If now, as in Figure 2 As shown in section d, raising the passenger door 11 causes the component of the connecting assembly 14 fixed to the passenger door 11 to detach from the component of the connecting assembly 14 fastened to the fuselage section 2. Specifically, the adjusting member 111b is raised from the first end of the flipping element 141b; however, the flipping element 141b is held in its position by the combined action of the recess 1411b formed at the second end of the flipping element 141b and the protrusion 1101b formed at the sealing bolt. Simultaneously, the operating member 15 detaches from the mechanism 101b, which is formed in the shape of a sealing bolt, and this mechanism itself remains rotatably engaged with the external engagement device 14b, that is, rotatably engaged with the elongated hole 142b of the external engagement device 14b. Thus, the life-saving slide rod 12, rigidly connected to the sealing bolt, is fixed to the fuselage section 2. Thus, the life-saving slide 13 is reliably positioned in the structure of the aircraft section 1 for use. Correspondingly, the fixing element 103 can be detached from the life-saving slide rod 12.

[0037] The passenger door assembly 10 described herein is advantageous in at least several of the following aspects:

[0038] • Smaller weight due to the reduced number of parts in the pre-positioning mechanism (especially due to the use of Bowden wire).

[0039] • The rescue slide arm remains in the same position relative to the rescue slide, door, and fuselage. Instead of moving the rescue slide arm (as the primary interface) during the pre-positioning / de-positioning process, only the sliding element (as the secondary interface) is moved during the pre-positioning / de-positioning process.

[0040] • The reduced complexity of the pre-positioning mechanism has a positive impact on production and installation time.

[0041] • Robust interfaces between doors, emergency slide bars, and the fuselage in terms of operation and tolerance effects.

[0042] • Less production and maintenance time / interruption.
