Abstract

Storage of chairs when not in use, for instance in halls used by various groups, is a common problem which has been addressed by providing chairs that are stackable upon one another. Usually, this requires the chair to be composed of sloping legs and a sloping backrest, such that the seat of a lower chair can fit between the legs of an upper chair, and the backrest of the upper chair can rest on the backrest of the lower chair. It is desirable to be able to stack chairs with as small a vertical displacement as possible, usually limited by the depth of the seat, which is typically substantiallyhorizontal. For instance, the base of an upper seat may sit (when stacked) on the upper portion of a lower seat. However, these chairs are usually mass produced and so designed to fit the average shape, which is not accommodating for a lot of people. The present invention provides a chair where seat (13) height, back (3) angle, seat (13) tilt and seat (13) roll are adjustable.

Description

technical field [0001] The present invention relates generally to stackable chairs and methods of adjusting the same, finding particular (but not exclusive) utility in stackable chairs used by orchestras. Background technique [0002] The storage of seats when not in use (for example, in an auditorium for various groups) is a common problem which has been addressed by providing stackable seats. This usually requires a seat consisting of sloping legs and a sloping back, ensuring that the seat surface of the lower seat fits between the legs of the upper seat and the backrest of the upper seat rests on the backrest of the lower seat. [0003] It should be possible to stack the seats with as little vertical displacement as possible, which is usually limited by the depth of the seat surface, which is usually substantially horizontal. For example, the base of the upper seat surface may be positioned (when stacked) on top of the lower seat surface. [0004] Another issue is the c...
