Description

[0026] The present invention will now be described by an example only with reference to the accompanying drawings in which:

[0027] FIG. 1 is a schematic perspective view of an aircraft seat arrangement according to an exemplary embodiment of the present invention in a first configuration.

[0028] FIGS. 2a and b are schematic perspective views of an aircraft seat arrangement according to an exemplary embodiment of the present invention in a second configuration.

[0029] FIG. 3 is a schematic perspective view showing in more detail the forward and rearward seat portions, particularly of the embodiment of FIG. 2a in the second configuration.

[0030] FIG. 4 is a schematic perspective view of the forward and rearward seat portions particularly of the embodiment presented in FIG. 2a in the first configuration.

[0031] Referring to FIG. 1, a complete aircraft seat assembly is presented made up of three individual passenger seating areas. The aircraft seat arrangement comprises a backrest 2, a support structure generally indicated by reference 4, and a forward and rearward seat portion 6, 8. In the first configuration as represented in FIG. 1 and FIG. 4 the forward and rearward seat portion seat 6, 8, are in a side-by-side configuration defining a forward seating surface 10 and rearward seating surface 12. The forward and rearward seat portions 6, 8, comprise spaced apart side edges 14, 16, wherein a bracket 18 is secured to the side edge of the forward seat portion 6 by fixing elements 20. In the first configuration, a stop portion 22 abuts the seat support structure 4 at an abutment surface 24. It will be appreciated that first and second brackets 18 are provided adjacent to opposing side edges of the forward seat portion 6 and in the first configuration where the forward and rearward seat portion 6, 8, are in a side-by-side configuration a force applied to the forward seating surface 10 is applied directly through the seat support structure via the stop portion 22 and bracket 18. Visible in the first configuration is a pocket 26 into which is received a lifejacket and/or other safety or passenger equipment.

[0032] In plan view the forward seating surface and rearward seating surface 10, 12, project a footprint downwardly onto the aircraft floor. As is visible in FIGS. 1 and 2 a void is provided within the seat footprint that defines a standing space for a person clearly presented in FIGS. 2a and 2b. As clear from FIG. 1 in the exemplary embodiment there is no support structure directly beneath a portion of the leading edge of the forward seat portion 6 and the leading edge of the forward seat portion 6 overhangs the support structure 4. In the exemplary embodiment the forward seat portion 6 is unsupported from underneath via the support structure 4. Instead, the forward seat portion 6 is supported by the bracket 18. The stop portion 22 abuts the support structure 4. As is visible in FIG. 2b, cross member 23 forms part of the support structure increasing stiffness of the seat. It will be appreciated that a passenger can still occupy the space defined within the seat footprint by standing on or either side of the cross member 23. The cross member 23 is spaced apart vertically from the forward and rearward seat portions 6, 8.

[0033] Referring now in particular to FIGS. 2a and b and also FIG. 4 the forward and rearward seat portions 6, 8, are in a second configuration wherein the forward seat portion 6 is displaced to be at least partially above the rearward seat portion 8. In the exemplary embodiment the bracket 18 pivots about pivot point 28 of the support structure 4 to the configuration wherein the forward surface seating 10 and rearward seating surface 12 are facing each other. The forward seat portion in this configuration defines a second forward seating surface 30. In this configuration a standing space for a person is defined or the seat can be used for a child. The rearward seat portion 8 is supported underneath by a platform 32 provided as part of the support structure. The platform 32 beneficially extends from the backrest 2 and is integrally formed therewith. Force therefore applied onto the rearward seat portion 8 is transferred directly to the support structure 4.

[0034] A mounting point 36 is provided for mounting an armrest relative thereto. Mounting points for a three point harness are also provided wherein one of the mounting positions is closer to the upper edge of the backrest than to the seat portions.

[0035] In use, the forward seat portion 6 can be pivoted between the first and second configurations by a passenger dependent upon their desired use.

[0036] The present invention has been described by way of example only and it will be appreciated to the addressee that modifications and variations may be made without departing from the scope of protection afforded by the appended claims.
