Abstract

An aircraft cabin comprising a credenza and a lounge chair disposed above the credenza is disclosed. The lounge chair is adjustable between a first configuration defining a first seating arrangement and a second configuration defining a second seating arrangement. Also disclosed is a mechanism to facilitate the adjustment of the lounge chair.

First claim

The invention claimed is:

1. A method of assembling a lounge chair comprising a mattress with an outer covering and a mechanism to facilitate adjustment of the lounge chair, the mechanism guiding movement of a backrest portion, a seat portion and a leg portion of the lounge chair, the mechanism being adaptable based on a property of the mattress selected for the lounge chair, said property of the mattress selected from the group comprising a material type of the outer covering, a thickness of the mattress and a firmness of the mattress, the method comprising:
adapting the mechanism based on the property of the mattress;
assembling the lounge chair using the mechanism adapted based on the property of the mattress;
receiving a component of the mechanism, a parameter of the component having: a first parameter value when the property of the mattress has a first property value; and a second parameter value different from the first parameter value when the property of the mattress has a second property value different from the first property value; and
assembling the lounge chair using the component;
wherein the mechanism is adaptable to produce a desired bending behavior of the mattress based on said mattress property, to reduce wrinkling of the outer covering when adjusting the lounge chair;
wherein the component of the mechanism is a curved rail and the parameter is a curvature of the curved rail;
wherein a pivot axis of the curved rail is associated with a neutral axis of the mattress; and
wherein the mechanism is adaptable to vary the pivot axis such that the neutral axis is positionable between a first position midway between an upper side and a lower side of the mattress and a second position wherein the neutral axis is closer to the upper side of the mattress than to the lower side of the mattress.

2. The method as defined in claim 1 , wherein the material type of the outer covering has a resilience for accommodating repeated bending and flattening of the mattress.

3. The method as defined in claim 1 , wherein the material type of the outer covering has a pliability for accommodating repeated bending and flattening of the mattress.

4. The method as defined in claim 1 , wherein adapting the mechanism comprises adjusting a bend radius of the mattress.

5. The method as defined in claim 1 , wherein adapting the mechanism comprises adjusting a location of a pivot axis for a portion of the mattress.

6. The method as defined in claim 1 , wherein adapting the mechanism comprises adjusting a position of a neutral axis associated with a bend location of the mattress.

7. The method as defined in claim 6 , comprising:
raising the position of the neutral axis when the property of the mattress is indicative of a first resilience; and
lowering the position of the neutral axis when the property of the mattress is indicative of a second resilience higher than the first resilience.
