Seat Support Bracket, Seat & Back 

July 2018

Note: 

If a powered device is used to 

tighten the screws, start at the lowest 

torque setting and slowly increase 

the torque until the screws are snug 

against the frame. Damage to the 

plastic seat could result if the

screws are over-tightened.

Seat Support Bracket Installation

Note: 

Seat Support Brackets are 

only available for EC16 & EC18 

(Large and X-Large) Intellect Chairs.

1. Carefully place chair upside down on 

a soft, protective surface. Locate the 

two front 20mm Torx screws securing 

the seat to the seat mounting plate 

and remove them using a Torx T20 

drive (Figure 1).

2. Position the seat support bracket 

onto the seat mounting plate so the 

wings of the bracket rest under the 

front of the seat. Align the holes of 

the bracket with the two front holes of 

the mounting plate and loosley start 

each of the two 20mm Torx screws 

previously removed in step 1. Using 

a Torx T20 drive, carefully tighten the 

two 20mm Torx screws. Take care 

to not over tighten or damage may 

occur to the plastic seat (Figure 2).
