Abstract
An expandable chair includes an extendable seat section which materially extends the width of the main seat section of the chair. When the width of the seat needs to be lengthened, lateral sections are provided which are rotated up from beneath the main center section of the seat and then locked adjacent to the center section. The lateral sections can be rotated down and locked beneath the center section when chair expansion is not desired. Extendable support arms, adjustable outward from the back section of the chair, are provided when the width of the seat's center section is lengthened. These support arms are located behind the back support section and are configured to be slid outward when needed. A unique rack and pinion gear system allows the support arms to be extended and locked in a plurality of lengths.

An expandable chair comprising:
- a seat comprising a back section and center section, a first lateral section rotatably connected to one side of the center section and a second lateral section rotatably connected to a second side of the center section;
- seat control means for rotating the first and second lateral sections from a first lateral section position in which the lateral sections are extended outward from the center section, to a second lateral section position in which the lateral sections are folded beneath the center section;
- and
- locking means for maintaining the lateral sections in both their first and second lateral section positions.
An expandable chair comprising:
- a seat comprising a back section, a first support arm extending out from one side of the back section and a second support arm extending from a second side of the back support;
- support arm adjustment means for extending the support arms from a first support arm position adjacent to the back section to a plurality of support arm positions outward from the back section;
- and
- support arm control means for actuating movement of the support arms between the first support arm position and the plurality of positions outward from the back section.
