Abstract: A chair having an articulating backrest that deforms when reclined to support an occupant's head or shoulders. A backrest assembly includes a mesh insert secured to a frame, which includes an upper frame section and a lower frame section interconnected by a pair of articulated joints. A push arm pivotally connects to the chair's seat assembly and to the backrest's upper frame section. As the chair reclines, the push arm restricts the angular movement of the upper frame section relative to a floor. The lower frame section moves forward relative to the upper frame section. Consequently, an angle formed between the lower frame section and the upper frame section decreases during recline, thereby supporting the chair occupant's head or shoulders. Optionally, a tensioning member may connect the mesh insert to the push arm to offset any loss of tension caused by the deformation of the frame during reclined.

Abstract: Horizontally movable arm pads are useful for, among other things, their ability to be ergonomically positioned. An arm pad comprises a pad cover and a pad pan and is attached to an arm support. In one embodiment, a pad is laterally movable with respect to the arm support. In another embodiment, a pad is capable of moving forwards and backwards. In yet another embodiment, a pad is capable of moving laterally and forwards and backwards.

Abstract: The invention provides a seating apparatus having a reclining movement with a corresponding seat lift movement. In one embodiment, the invention is directed to a seating apparatus comprising a base, a curved support bar pivotally connected to the base, a plurality of ramps attached to one of the curved support bar and the base, and a plurality of rollers attached to the other of the curved support bar and the base for interacting with the plurality of ramps. As a user reclines, the plurality of rollers operatively engage the plurality of ramps to lift the seat of the apparatus. The combination of the reclining movement with the corresponding seat lift movement is particularly beneficial for providing an increased level of user comfort throughout a range of seating positions.

Abstract: A mesh chair component having contours that support a user appropriately can be made by combining a plurality of mesh panels to form the component. For instance, in a preferred embodiment of the present inventions, three preformed mesh panels are combined to form the back rest of a chair that provides its user with lumbar support without the necessity of additional structural support. In an alternative embodiment of the present invention, mesh panels are used in combination with a beneficially contoured frame to provide a chair seat with a waterfall front.

Abstract: The invention provides a chair armrest that is variably adjustable to allow a user to assume an ergonomically preferred sitting position. The ergonomic chair armrest comprises, either separately or together, an arm support assembly capable of adjustment to various positions through a vertical plane and an arm pad assembly capable of adjustment to various positions through a horizontal plane. The invention further provides an ergonomic chair having an armrest that is adjustable in both a vertical plane and a horizontal plane.

Abstract: The invention provides a seating apparatus having a reclining movement with a corresponding seat lift movement. The apparatus further provides a seating support surface having increased comfort comprising a shaped diaphragm with a series of calculated openings provided throughout.

Abstract: Disclosed is an adjustable armrest that can readily raised, or lowered, and optionally rotated in a horizontal plane. In one embodiment, the present armrest is released from its use position be raising the front portion of the armrest. The armrest is moved into the desired position and then the front portion is lowered to secure the armrest in the desired position.

Abstract: In the specification and drawings an armrest is described and shown with an arm, the arm having a support portion and a body portion; a channel extending longitudinally along the support portion, the channel having an open face along at least a portion of its length; and a bracket, the bracket being slidably engaged with the channel. Also in the specification and drawings an armrest is described and shown with an arm, the arm having a support portion and a body portion; and a bracket, the bracket being slidably engaged with the arm such that the lower end of the support portion extends below the bracket when the arm is in a lowered height position.
