Adjusting Rear Seat Height; M.depth Adjustable Backrest - Quickie 7R Mode D'emploi

Q UI C KIE 7R
L. ADJUSTING REAR SEAT HEIGHT
NOTE – Adjustment to rear seat height may also require caster angle adjustment. See Section P.
NOTE – If chair is configured with the 1B axle plate, the shorter camber tube clamps will be needed to lower rear
seat height by 1/2 inch. If configured with a 1A axle plate, it cannot be lowered and needs longer camber
tube clamps in order to raise seat height
a. Remove the set screws (A) on the rear side of the axle plate and the button head screw (B) on
the front.
b. To increase the Seat To Floor Height add a spacer (C) to the camber tube clamp (D).
c. Install clamp (C) over the top of the fork assembly inserting the inside tab (D) in the front
slot (E).
d. To reduce the Seat To Floor Height remove the spacer (C) from the camber tube clamp (D).
e. No more than two spacers per side are to be used. Once complete, insert the camber system
(D) in the axle plate and tighten screws to 62 in-lbs (7 Nm).
M. DEPTH ADJUSTABLE BACKREST
1. Remove Backrest and Backrest Bracket
a. Remove the wheels to gain access to the screws (E) holding the
back bracket and back post to the Chair frame. (F)
b. Using a 10mm wrench, and a 5mm Hex Key, remove and save the
Backrest bracket screw washer, and nut (G) for reassembly.
Remove the backrest and brackets. Repeat this process for the
opposite side of the chair.
c. Using a pair of needle-nose plyers, remove the C-clip (H) and set
screws in the housing ( I ) Detach Lanyard ( J ) and hardware from
the backrest bracket . Save the backrest hardware for reinstallation.
d. If the desired back depth is 1" greater, move the plunger bushing
back one hole. If the desired back depth adjustment is 2", the
plunger bushing must be moved to the most rearward hole. Insert
the pivot bushing received with the owners manual into the hole
from which the original bushing was removed.
e. To reassemble the back, reinsert the springs into the bushings (K).
Then reinsert the quick-release pins into the bushings. Thread the
lanyard into the housing and tighten the set screws( I ).
f. Reposition the backrest in place in the folded position. Insert the
quick-release pin into its appropriate placement hole.
g. Working on one side of the chair at a time, insert the large beveled
washer in between the backrest bracket and the frame. Insert the
backrest plate pivot bolt into the chair and secure using the washer
and nylock nut.
h. Using the 5mm and 10mm Allen Wrench, tighten the nylock nut so
that the end of the bolt reaches the end of the nut. Repeat on the
opposite side of the chair.
NOTE - Do not over-tighten the backrest plate pivot bolt as it may hinder
the backrest from folding properly.
i. Reattach the JAY®-style quick-release lanyard to the quick-release
pins.
NOTE - This adjustment is intended to compensate for differences in
after-market backrest thickness and/or contour. The back-canes
can be adjusted ford and aft relative to the seat, so that the back-
rest support surface does not change the location of the user,
regardless of the backrest mounting location. This ensures that
the center of gravity of the user relative to the axle location, is
not altered due to after-market backrest thickness or contour.
There is no recommendation for Depth Adjustable Backrest use
for transit.
