Chair

An improved mechanism for positioning loads of varying magnitudes, such as LCD displays, etc. The position of the load can be varied in height and angle according to the requirements of the user. The mechanism incorporates an adjustable sliding fulcrum, a support arm, a housing with four generally perpendicular channels, and a gas spring. The mechanism is initially manually adjusted for a particular load and then it automatically adjusts proportionally for the varying moments generated as the position of the load changes. The load is therefore evenly counterbalanced throughout its range of motion, and its position is maintained.

Position adjustable load support mechanism

A chair seat that is movable between an upright and a forward position includes a spring mechanism that biases the seat toward the upright position. The spring mechanism includes camming structures that utilize both compressional and torsional forces from the spring to bias the seat toward the upright position. The compression of the spring exerts a positive force that must be overcome before the seat can be moved out of its upright position. The chair seat is constructed from a number of discrete components that are secured together without the use of welding or separate fasteners, such as via snap-fits. The discrete components include positioning tabs, special shapes, and other features that prevent them from being improperly assembled. The components of the chair seat may all be constructed out of suitable durable plastics, such as polypropylene, polyethylene, polycarbonate, and glass filled thermoplastics.

A plastic contoured seat back includes an inner and an outer shell affixed together. The inner shell includes a three dimensionally curved front surface and a two dimensionally curved back surface. The inner shell may include an internal rib adjacent the top of the shell that is shaped differently from the top edge of the inner shell. The internal rib is adapted to allow the inner shell to be cut adjacent the internal rib so that the inner shell can be varied in shape. The shell may also include indentations on the back side of the shell adjacent the corners of the inner shell. The indentations are dimensioned to receive overlapping fabric that is pulled around the corners such that the fabric on the back of the shell adjacent the corners does not project outwardly more than the fabric elsewhere, despite the over lapping of the fabric at the corners. The inner shell may also include a plurality of uniquely identified holes adapted to allow a variety of different ornamentation to be attached to the inner shell.

A plastic contoured seat back includes an inner and an outer shell affixed together. The inner shell includes a three dimensionally curved front surface and a two-dimensionally curved back surface. The inner shell may include an internal rib adjacent the top of the shell that is shaped differently from the top edge of the inner shell. The internal rib is adapted to allow the inner shell to be cut adjacent the internal rib so that the inner shell can be varied in shape.
