PRODUCT DESCRIPTION
A. Proprietary Seating Systems: Self-Returning Swivel Seating / 360° Healthcare Swing Arm Seating:
Clarin by Hussey Seating Company. Provide chairs with manufacturer’s features specified below:
B. Pedestal/ Base Plate Structure: Each pedestal is constructed of 1-1/2” [38mm] X 3” [76mm heavy gauge
3/16” [5mm] carbon-steel tubing. The lower portion of the pedestal, where the arm assemblies attach, shall
be 90 degrees to the floor. Pedestal shall have a full perimeter electric arc weld to a base plate. The weld
bead shall be no less than ¼” thick. The 5” [127mm] X 6-1/2” [165mm] steel base plate is designed with
four (4) holes which accept anchor bolts (not furnished). ABS cover for base plate. Assembled
understructure must withstand a 200-lbs. [91kg] rigid load dropped two inches without permanent
deformation.
C. Seat Support Arm Assembly: Each pedestal will receive one or two seat support arms. The seat support
arms are constructed of 1” [25mm] X 2” [51mm] 11 gauge steel tubing. Support arms shall be supported
at the pedestal and work independently of each other. Each support arm is secured to its own 1-3/4”
[44mm] X 2” [51mm] X1” [25mm] cold rolled steel top bracket. These top brackets, along with two lower
brackets, are attached to the pedestal with a full perimeter electric arc weld with a bead no less than ¼”.
Attachment of arm to pedestal brackets is accomplished by utilizing a ½” [13mm] diameter X 4-5/8”
[117mm] long hardened steel axle pin riding on a 5/8” [16mm] long oil impregnated bearing for selflubricating at the top. A flange bearing at the bottom of this pin assembly shall provide for adjustment of
Page 4 of 6
SRSS Series | 360° Healthcare Swing Arm Seating |Institutional Furniture Rev. 2-2014
the torsion spring tension, which returns the arm to its unoccupied position. This flange bearing shall ride
on a self-lubricating bronze thrust bearing impregnated with high-grade mineral oil of no less than SAE 30
viscosity. Return spring system should be fully enclosed and field adjustable without removal of arm
assembly. Any spring mechanism not adjustable in the field will not be approved. Arm to pedestal
assembly shall be designed with no cover plates eliminating any pinching hazards.
D. Table Top Support Plates: The table top support plates of the pedestal assembly shall be made of 11
gauge carbon steel wit powder coat finish. They are design to eliminate the need for unsightly shims by
adjusting for height and angle to level the tabletops due to uneven floors. Systems using shims will not be
accepted. Top plates shall be secured to the pedestal by two 3/8” [9mm] –16NC X 2-1/4” [[57mm] long
hex bolts passing through sleeves within the pedestal.
E. Seat Mechanism: The seat undercarriage bracket utilizes a solid steel support post, which is inserted
through the top of the support arm and also through a flanged nylon sleeve. The seat shall be mounted on
an auto centering gas cylinder with 2 1/2” [63mm] lift. Adjustable height cast foot ring which provides
patron assistance getting into and out of the seat shell while also providing a foot resting position.
