Abstract
A swivel assembly for use in a seat suspension having a first swivel plate and an opposingly located second swivel plate with a plurality of ball bearings disposed between the swivel plates. The bearings permit the first swivel plate to rotate with respect to the second swivel plate. A lip is located inwardly from the bearings on the first swivel plate with the lip defining an aperture. An adjustment plate having an outer edge engages the lip. The adjustment plate also includes a plurality of sloped adjustment surfaces which increase in height and which have slots formed in the sloped adjustment surfaces. A plurality of fasteners extend through the slots into the second swivel plate and further engage the sloped adjustment surfaces. The adjustment plate and the sloped surfaces are rotatable about the fasteners to increase or decrease the pressure exerted on the bearings by urging the first plate towards or away from the second plate to adjust the rotational movement of the second swivel plate with respect to the first swivel plate.
