Abstract
A folding chair (100) comprises as main components a mainframe (1), a seat (2) and a back leg support (3). At least one of the main components is uniplanar and the others fit within a plane of the at least one main component when the chair (100) is collapsed. The folding chair (100) uses a type A construction, and forward movement of the top of the seat (2) relative to the mainframe (1) causes the back leg support (3) to move backwards relative to the mainframe (1).
Claims20
A folding chair comprising as main components a mainframe, a seat and a back leg support, wherein:
- at least one of said main components is substantially uniplanar and the other said main components fit within a plane of the at least one main component when the chair is in a collapsed state;
- the folding chair uses a construction, wherein forward movement from the collapsed state of the folding chair of a top of the seat relative to the mainframe causes the back leg support to move backwards relative to the mainframe for unfolding the folding chair;
- the mainframe comprises a backrest and plural front legs extending downwards from outer sides of the backrest and seat supports spaced inwards from the front legs and also extending downwards from the backrest partially along with the front legs and defining spaces between the front legs and seat supports;
- the seat is pivotally attached to the seat supports;
- and
- wherein the back leg support comprises a pair of back legs, each of which is disposed in one of the spaces between a corresponding front leg and seat support when the chair is collapsed;
- and
- the seat supports extend from the backrest partially down the back leg support, when the chair is collapsed, and connect to the seat.
