Interior flange for slide-room

A method, comprising:

• mounting a base member on an outer surface of a secondary structure;
• installing the secondary structure in an opening defined in a wall of a primary structure such that the secondary structure is movable through the opening between an extended position and a retracted position;
• and
• coupling a flange member to the base member with a coupling portion of the flange member, the flange member including a main flange portion from which the coupling portion extends, the main flange portion further including a first portion and a second portion, the second portion being on the opposite side of the coupling portion from the first portion;
• wherein the flange member is coupled to the base member such that the first portion of the main flange portion is adjacent a rear wall of the secondary structure, and such that the second portion of the main flange portion extends beyond the outer surface of the secondary structure.

A vehicle, comprising:

• a vehicle wall having an opening;
• a slide-room mounted within the opening and being moveable relative to the wall between an extended position and a retracted positon;
• and
• a flange assembly for sealing a space between the slide-room and the wall, the flange assembly comprising:
• a base member mountable to an outer surface of the slide-room;
• a flange member including a main flange portion and a coupling portion extending from the main flange portion, the main flange portion including a first portion and a second portion, the second portion being on the opposite side of the coupling portion from the first portion, the coupling portion being coupled to the base member such that the first portion is adjacent a rear wall of the slide-room and the second portion extends beyond the outer surface of the slide-room;
• and
• wherein the second portion of the main flange portion is configured to engage an interior surface of the wall of the vehicle when the slide-room is in the extended position.
