Embodiment Construction

[0066]Throughout the figures, the same figures references have been used to refer to the same features of the invention.

[0067]The figures show an adjustable chair 10 comprising a seat base 12 adapted to receive a user thereon in use and defining an exposed seating surface area 14 for receiving a user thereon in use. Seat base 12 is substantially planar. Although shown as a one-piece moulding, it will be appreciated that the seating surface area 14 may padded for the comfort of the user. In the embodiment shown, the front edge 40 of seat base 12 is shown as curved, in a contour known in the industry as a ‘waterfall’ front edge. This assists with the comfort of a user and the back of a user's knees are supported by a smooth curved surface.

[0068]The chair 10 further comprises a seat back 16. Seat back 16 has an elongate U-shaped seat base engagement portion 18 and seat base 12 has a corresponding seat back engagement portion 20 which is an elongate tubular structure and is dimensioned ...

Abstract

The present invention relates to an adjustable chair (10) comprising: a seat base (12) defining a seating surface portion (14) for receiving a user thereon in use, the seat base (12) comprising an integral seat back engagement portion (20) for engaging with a portion of a seat back (16), a seat front portion (40) opposing the seat back engagement portion (20), a first seat side portion and a second seat side portion opposing the first seat side portion, each of the first and second seat side portions located between the seat back engagement portion (20) and the seat front portion (40) and extending substantially transverse to the seat surface portion (14); and a seat back (16) having a seat base engagement portion (18) dimensioned to slidably engage with the seat back engagement portion (20) to form a seat back adjustment mechanism, wherein the seat back adjustment mechanism is located adjacent at least one of the first and second seat side portions and wherein the seat back adjustment mechanism is movable between a first locked configuration in which the seat back (16) and seat base (12) are fixed relative to one another and the seating surface portion (14) has a fixed surface area, and a second released configuration in which the seat back (16) is slidable relative to the seat base (12) to vary the surface area of the seating surface portion (14). Also provided is such a chair with an adjustable footrest (22) to vary the distance between the seat base (12) and the footplate (54) and/or to vary the angle between the seat base (12) and the footrest (22).

Description

BACKGROUND OF THE INVENTION[0001]Conventional chairs are designed to fit and support a user's body. Some are adjustable with respect to arm rest height or the incline of the back support. Some include adjustable lumbar supports for optimal support of the user's spine.[0002]However, these adjustability options are not sufficient for a chair for use by users of multiple heights and body shapes. For example, a school chair may be used by a schoolchild over many months, during which time the schoolchild will be growing in height and weight. Gradually, they will outgrow the chair which leads to discomfort, poor posture and potentially back pain. Alternatively, a school chair may be used by more than one child of differing heights and body shapes on a regular basis. However, without sufficient adjustability the chair will not be suitable for all.[0003]As children grow, their leg length increases. Thus, an increase in their lower leg length will require a chair of increasing height to ensu...
