CABIN SEGMENT HAVING A VACANT SPACE

Abstract

A cabin segment of a passenger cabin of a passenger aircraft is directly adjacent a cockpit along a longitudinal axis of the aircraft and includes a cockpit bulkhead transverse to the longitudinal axis which separates the passenger cabin from the cockpit. The cockpit bulkhead contains a cockpit door, wall portions of left and right-side fuselage walls having respective cabin doors and an emergency exit region to be kept free which connects the cabin doors. The cabin segment ends level with foremost passenger seats and contains a sub-space left of the cockpit door and a sub-space right of the cockpit door. One of the sub-spaces is a vacant space between the cockpit bulkhead and the foremost passenger seats which extends to the fuselage wall and contains neither a galley nor a lavatory.

Description

BRIEF DESCRIPTION OF THE SEVERAL VIEWS OF THE DRAWING

[0040] FIG. 1 is a fragmentary, diagrammatic, top-plan view of a passenger aircraft having a cabin segment according to the invention; and

[0041] FIG. 2 is a fragmentary, top-plan view of a vacant space of the cabin segment of FIG. 1 in alternative embodiments.

DETAILED DESCRIPTION OF THE INVENTION

[0042] Referring now to the figures of the drawings in detail and first, particularly, to FIG. 1 thereof, there is seen a passenger aircraft 2 which has a longitudinal axis 4 and an intended straight-ahead flight direction 6 in the direction of the longitudinal axis 4. The passenger aircraft 2 has a cockpit 8 at the front (indicated as V in the figure) in the flight direction 6. A passenger cabin 10 is adjacent the cockpit 8 towards the rear (indicated as H in the figure) along the longitudinal axis 4. The passenger cabin 10 in FIG. 1 has a cabin segment 12 which is bordered by a dashed line and is directly contiguous to the rear of the cockpit 8.

[0043] The cabin segment 12 contains a cockpit bulkhead 14 which separates the cockpit 8 from the passenger cabin 10. The cockpit bulkhead 14 runs transversely to the longitudinal axis 4 and contains a cockpit door 16 in the form of a rearwardly offset convexity.

[0044] The cabin segment 12 moreover contains a left wall portion 18a (L indicates the left side in the figure) of a left fuselage wall 20a having a left cabin door 22a, and a right wall portion 18b (R indicates the right side in the figure) of a right fuselage wall 20b having a right cabin door 22b.

[0045] An emergency exit region 24 has a single center aisle 26 between two seat rows of respective passenger seats 28 (in this case rows of three seats which are not referred to in more detail) which connects the two cabin doors 22a,b. The passenger aircraft 2 by virtue of having only one center aisle 26 is a single-aisle aircraft.

[0046] Moreover, the cabin segment 12, in the present case, includes two foremost passenger seats 28a,b of a left foremost seat row (in this case a row of double seats). The cabin segment 12 ends at the foremost passenger seats 28a,b at the rear in the longitudinal direction.

[0047] The cabin segment 12 contains a left sub-space 30a to the left of the cockpit door 16, as well as a right sub-space 30b to the right of the cockpit door 16. Both sub-spaces 30a,b are in each case indicated by a partially hatched area and centrally delimited by a dashed line.

[0048] The left sub-space 30a is embodied as a vacant space 32. The vacant space 32 extends in the longitudinal direction from the cockpit bulkhead 14 up to the foremost passenger seats 28a,b (including the latter), and extends in the transverse direction from the cockpit door 16 up to the left fuselage wall 20a, or the left wall portion 18a, respectively.

[0049] The vacant space 32 contains neither a galley 34 nor a lavatory 36. A partition 38, which in passenger aircraft of this type is often disposed between the passenger seats 28 and an entrance region close to the left cabin door 22a, is not present in this case and is therefore only indicated by dashed lines.

[0050] The galley 34 and the lavatory 36 are disposed outside the vacant space 32, specifically in the right sub-space 30b. The galley 34 in this case is I-shaped, that is to say in a linear manner along the longitudinal axis 4. An alternative embodiment of a galley 34 in an L-shape, which is formed by an additional protrusion 40 of the galley 34 at the rear end of the latter, is illustrated in dashed lines. The protrusion 40 projects towards the vacant space 32, or towards the cockpit door 16, respectively, in the transverse direction (in relation to the longitudinal axis 4).

[0051] The galley 34 and the lavatory 36 in this case are embodied as an integrated monument 42, specifically a so-called gallatory. The monument 42 having the L-shaped galley 34 is contoured by a dashed line.

[0052] The galley 34 in the transverse direction (of the aircraft 2) is disposed beside the lavatory 36 in the direction towards the cockpit door 16. The galley 34 has an operating side 44 (indicated by an arrow) which in the transverse direction points towards the cockpit door 16, or towards the left fuselage wall 20a. Service personnel of the galley 34, when using the latter, can thus be present in the vacant space 32, or behind the cockpit door 16, respectively.

[0053] Two cabin attendant seats 46a,b are disposed in the vacant space 32 between the cockpit bulkhead 14 and the emergency exit region 24. The two cabin attendant seats 46a,b are aligned counter to the flight direction 6, or point in that direction, respectively. The cabin attendant seats 46a,b in FIG. 1 are disposed directly on the cockpit bulkhead 14.

[0054] FIG. 2 shows alternative embodiments of the vacant space 32 of FIG. 1. The cabin attendant seats 46a,b in this case are part of a cabin attendant monument 48. Apart from the cabin attendant seats 46a,b, the cabin attendant monument 48 also contains respective filling elements 50a,b, or 50c. The filling element 50a is a stowage compartment (not explained in more detail herein) which is disposed between the cockpit bulkhead 14 and the cabin attendant seats 46a,b in the longitudinal direction. The filling element 50b is disposed between the left cabin attendant seat 46a and the left fuselage wall 20a, and in a manner not explained in more detailed contains a dog house (mini stowage unit) as well as a pull-out table. A further filling element 50c which is optional and therefore indicated in dashed lines is only attached as an overhead stowage compartment (not explained in more detail) above the cabin attendant seats 46a,b.

[0055] The foremost passenger seats 28a,b, when viewed in the direction counter to the flight direction 6, are disposed in the cabin segment 12 so as to be directly behind the emergency exit region 24. This means that only a minimum permissible spacing AN, in this case 2.5 inches, from the emergency exit region 24 has been adhered to.

[0056] Furthermore, a minimum spacing AS of 60 inches is prescribed in this case between seat reference points PP (the longitudinal position of the latter being indicated by a straight line) of the passenger seats 28a,b and seat reference points PF (indicated by a corresponding straight line) of the cabin attendant seats 46a,b. The seat reference points PF of the cabin attendant seats 46a,b in FIG. 2 are plotted so as to be specific in terms of the actually illustrated installation position of the cabin attendant seats 46a,b.

[0057] Therefore, a rearmost permissible assembly position of the cabin attendant seats 46a,b is derived for a given assembly position of the passenger seats 28a,b so that the minimum spacing AS is still just adhered to. The seat reference points PF of the cabin attendant seats 46a,b at the rearmost assembly position of the latter must thus be at most at the transverse line 52, or must be in front of the latter. A spacing range BA for permissible installation positions of the cabin attendant seats 46a,b, or of the seat reference points PF of the latter, which in FIG. 2 is illustrated by a double arrow is thus derived. The spacing range BA therefore extends from the transverse line 52 up to the cockpit bulkhead 14. FIG. 2 shows that this condition is met for the illustrated installation position.
