Abstract: A seating system is provided including a beam for supporting seats, wherein the seats are individually mounted to the beam at any selected longitudinal position along the beam. The system facilitates seat positioning and repositioning in a manner that optimizes seating adaptability and ease of installation. The beam preferably includes integral first and second track portions. The first track portion includes a channel that receives bracket-mounted connectors by which the beam is fixed relative to the ground. Each of the seats has at least one seat support with a clamp portion that secures to the second track portion of the beam, free from the channel to avoid interfering with the connectors, regardless of the point at which the support is clamped to the beam. The second track portion is preferably shaped to include a rear overhang and front overhang defining oppositely directed undercut surfaces on which the seat support is securely mounted.

Abstract: A chair or seat, for use in theaters and/or stadiums, having a back member, a seat member, an armrest construction, a pivot assembly comprising an aperture on an arm or frame of the chair, a pivot member associated with a chair seat, and a bearing member which can act as a bearing for the rotation and a buffer at the extremes of the rotation whilst ultimately retaining the pivot assembly together, and a counterbalance to enable rotation about a pivot point, whereby the rotational movement is controlled. The chairs are made from a moulded plastics material with core recesses to impart substantial rigidity to the chair, and can readily be connected to a surface such as a beam, a riser or a tread via a connection means which is connected to the back of the chair.
