Arm supports continued. . .
Forearm prompts adjust fully to
facilitate trunk and head control
while sitting. Forearm prompt pads,
clamps and posts are identical to arm
prompts used on the Rifton Pacer
and the Rifton Dynamic Stander.
Forearm prompts are attached using a
clamp and post system (see Figure 12b).
The clamp attaches with a screw knob (F)
to any position on the bar. The clamp can
be mounted on the inside or outside of the
bar (G) (see Figure 12a).
The post fits into the clamp and provides
up/down and rotational adjustment.
Arm prompt can be attached to the post
in several positions by sliding or rotating
to achieve the best position for the user.
Loosen the single knob (A) underneath to
make adjustments (see Figure 12b).
Adjust the forearm prompts to the best
position for user’s comfort and function.
Slide or rotate the handgrip (see Figure
12b), by loosening, then tightening knob
(C) on the side. Adjust straps (D and E) (see
Figure 12a) and secure with hook and loop
fasteners (hooks away from the user’s arm).

Move seat forward or back to desired
position and release handle. Make sure
seat clicks into place.
Tilt-in-space
Tilt-in-space moves entire seat and
backrest from a rest position to
active sitting and vice versa.
To adjust tilt-in-space angle, place one
hand on push handle or top of backrest
and with other hand simultaneously
squeeze tilt lever and safety lock (see
Figure 13b). Push forward or pull backward
on push handle or backrest until desired
angle is reached, then release levers to lock
seat and backrest into desired position.
Use angle indicator (see Figure 13c) on side
of chair for consistent positioning.

Back and seat springs
Spring option allows for user-
initiated movement and allows chair
to “bounce.”
The Standard base with spring option
has spring in backrest and seat (see
Figure 14c).
The Hi/Lo base with spring option
has spring in backrest only.
There are two locked (non-dynamic)
positions on the backrest gas spring.
When locked, each position provides 15˚ of
angle adjustment using the backrest angle
lever. The seat spring also has two locked,
(non-dynamic) positions, each providing 15˚
of adjustment using the tilt-in-space lever.

(on standard base models only):
If the seat has a gas spring (located under
the seat) it will also have the two locked
(non-dynamic) positions allowing an extra
15˚ of recline from the tilt-in-space. To
unlock the seat spring, rotate the twist-lock
collar under the seat counter-clockwise.
Turn it clock-wise to lock it and then
use the tilt-in-space lever to make final
adjustments.
Figure 16b
Figure 16a
Relax mode (-20˚ to -5˚):
To position and lock the backrest for
reclined resting, unlock the white twist-lock
collar (see Figure 14b). Push down and
back on the top of the backrest (not on
the headrest) until the groove around the
movable gas cylinder almost retracts into
the outside cylinder. While still holding the
backrest down, turn the white twist-lock
collar to the right until it locks. This
function is easier to perform with your
client in the chair. Once locked, adjust the
angle of the backrest forward or back 15˚
using the angle lever (see Figures 16a and
16b).

Seat quick-connect
Every Rifton Activity Chair seat
and backrest unit can be detached
from its base and re-attached to
any other Rifton Activity Chair base
of the same size. Thus, a Rifton
Activity Chair Standard base can be
converted to a Hi/Lo base and vice
versa, by ordering the base required.
To detach seat and backrest unit from base,
first disconnect footboard angle adjuster, if
footboard is present (see Figure 17a). Also
lock casters, if casters are present, and
remove arm supports from chair.
With footboard angle adjuster
disconnected, casters locked and arm
supports removed, find two white levers
(A) located directly beneath the chair seat
(see Figure 17b). Place one hand under
front edge of seat and lift it upwards. At
the same time, with the other hand, pull
one of the two levers (A) towards front of
chair. Still lifting front edge of seat, pull
second lever (A) towards front of chair to
completely disengage bottom of seat from
crossbar (B) beneath it.
Once front of seat is disengaged, pull entire
seat and backrest unit towards front of
chair and away from base until seat hoop
(C) completely disengages from metal
prongs (D) (see Figure 17c).

If the seat is being installed on a Hi/Lo
base, raise the base to its full height first.
To attach seat and backrest unit to base,
slide seat hoop (C) under prongs (D) on
base, centering backrest column between
prongs (see Figure 17c). Then lower seat
onto crossbar (B) (see Figure 17b), pushing
firmly down on front edge until it snaps
into place.
Reconnect footboard adjustment tubing to
its housing by holding housing and tubing
in straight line to one another, depressing
tube latch, inserting tubing into housing
and making sure it clicks into place at
desired setting (see Figure 17a).
Note: The process of detaching
seat from base and re-attaching it
to another base works best when
performed with two people, one on
either side of chair.
WARNING
Make sure seat is firmly attached, front
and back, before use.
