Structure system for installation into a fuselage structure

A structure system for installation into a fuselage structure in an interior of an aircraft, comprising:

• at least one first carrier element,
• at least one second carrier element,
• at least one elongate frame element having a first end and a second end,
• at least one first attachment device for attaching the first carrier element to the fuselage structure or to an element coupled with the fuselage structure,
• at least one first coupling device mounted to the first end for coupling the first carrier element to the at least one elongate frame element, and
• at least one second coupling device mounted to the second end for coupling the second carrier element to the at least one elongate frame element,
• wherein the at least one elongate frame element is configured for holding at least one component to be installed in the interior,
• wherein the at least one first carrier element is configured for coupling with the at least one first coupling device,
• wherein the at least one second carrier element is configured for coupling with the at least one second coupling device, and
• wherein one of the at least one first coupling device and the at least one second coupling device is configured to snap into the respective carrier element, to be moved relative to the respective end of the at least one elongate frame element and to be arrested in a desired relative position thereto.
