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.
Claims24
A chair or seat having a back member, a seat member, a frame, and a pivot assembly operable to pivotally mount the seat member relative to the frame, the pivot assembly comprising:
- an extension projecting from the frame of the chair;
- a pivot member fixed to the seat member, the pivot member including a skirt portion and a central annular member;
- and a bearing member including a pivot bush that extends through an interior of said annular member, the pivot bush having a central hollow portion that receives said extension, wherein the pivot bush is secured relative to the frame and includes least one radially extending spring member to act against the skirt portion as a buffer at extremes of rotation of the seat member.
A seat comprising:
- a pair of side supports;
- a pivotal seat member;
- and
- a pair of pivot assemblies operable to pivotally mount the seat member relative to the frame generally between the side supports, each of the pivot assemblies including:
- a pivot member connected to the seat member, the pivot member including a skirt portion defining a cavity with a plurality of inwardly directed indentations;
- and
- a spring body disposed in the cavity, the spring body having a central bush that is secured relative to a respective one of the side supports, the spring body including a plurality of spring members, each spring member extending radially from the central bush, wherein the spring members act against the inwardly directed indentations to rotationally bias the pivot member through at least a degree of motion of the seat member.
