Patent ID: 7159940

Claim:
A swivel seat device, comprising: a non-rotatable, circular-shaped lower supporting member having a periphery and at least two transverse channels extending across the diameter of the lower supporting member; a circular-shaped upper supporting member having a seating surface and an opposite interior surface, the upper supporting member mounted eccentric to the lower supporting member for selective eccentric rotatable motion relative to the lower supporting member so that a portion of the upper supporting member is pendent and eccentric to the lower supporting member when the upper supporting member is disposed to a fully rotated position; swiveling means interconnecting the upper supporting member to the lower supporting member for allowing the selective eccentric rotation of the upper supporting member relative to the lower supporting member; and a pair of flexible straps that are partially received within the channels of the lower supporting member and which wrap around the lower supporting member and a seat rest of a chair upon which the lower supporting member is superposed for scouring the swivel seat device to the chair.
