Tradition. Innovation. Vision.
For the last two and a half decades, Invacare has been
the industry leader in power chair electronics and
bases. Every year, Invacare's engineers design chairs,
electronics, components and features that consistently
raise the bar for power wheelchair performance.
Invacare’s rich power chair history started with
the original Power Rolls IV Wheelchair in 1981, and
continued with innovations such as the original MKI
electronics in 1989, and the Invacare® Storm Series®
power chairs in 1995.
Invacare revolutionized the power chair industry once
again in 2003 with the introduction of the Invacare®
TDX® (Total Driving eXperience) power chair. With
innovative features such as True Center-Wheel Drive,
Invacare® SureStep® Suspension, Stability Lock,
Invacare® Traction Control Design TCD™ Relative
Movement and the latest MK series electronics, this
chair set the standard for high end rehab power chairs.

The Invacare® TDX® SP wheelchair led the way.
Now Invacare has done it again. Invacare built upon a legacy of power chair knowledge
and design to develop the Invacare® TDX® SP wheelchair. The TDX SP wheelchair
improves upon all the features of the TDX Series with enhanced performance, superior
ride quality, overall quieter chassis and an elegantly simple design that is sure to turn
heads. Invacare is the only choice for a complete package of Custom Rehab Solutions.

Traction Control Design.
Enhanced Invacare®
SureStep® Suspension.
The Invacare® TDX® Family uses an
enhanced version of Invacare’s patented
Invacare® SureStep® technology that was
made famous on the first generation TDX
line and the Invacare ® Pronto® series of
wheelchairs.
With Enhanced Invacare® SureStep®
Suspension, the TDX SP and TDX SR
wheelchairs climb up to a 3" obstacle
going forward; the TDX SC and the TDX
SPREE wheelchairs climb up to a 2.5"
obstacle. As a new design feature, the
front casters also will drop a full 3", which
makes transitioning down an obstacle very
gentle and nearly silent. The integrated
Invacare® Traction Control Design TCD™
Relative Movement also makes climbing
over obstacles up to 1" high in reverse
nearly effortless.

Electronics. Designed
with Benefits for All.
MK Series electronics are the
benchmark in power wheelchair
drive systems. This is the result of
years of experience in the design
and manufacture of electronics
specifically for the needs of
wheelchair consumers.
Invacare® MK6i™ electronics take
the MK Series to the next level by
offering features that are easier to
use than any other MK Series system.
Advantages of MK6i electronics
include:
• Invacare® MK5™ programming
logic, so operators do not need to

True Center-Wheel Drive.
The tightest possible turning radius
comes from the True Center- Wheel Drive
chassis. The Invacare® TDX® Family
uses this type of wheelbase to provide
excellent maneuverability and an
intuitive driving experience. This
technology combined with Enhanced
Invacare® SureStep® Suspension,
Traction Control Design and Quiet
Stability Lock makes the TDX wheelchair
a great indoor and outdoor chair.

Quiet Stability Lock.
Quiet Stability Lock.
The Difference Maker in Rehab.
The original Invacare® TDX®
wheechair introduced quiet Stability
Lock, a feature that kept the power
chair stable whenever it felt that the
driver's weight was rocking forward.
The TDX Family takes that same
feature to the next level. The Stability
Lock feature is designed to operate
and keep the power chair stable
while it is in motion. It is not intended
to operate while the power chair is
at rest. This second generation
Stability Lock replaces the metal
gear set used on the first generation
TDX wheelchair with a gas locking
cylinder, making the feature whisper
quiet. It also provides a shock-
absorbing effect.

The Invacare® TDX® SP wheelchair is
the first model in the next generation
of TDX (Total Driving eXperience)
power wheelchairs. The TDX SP
wheelchair takes all the best features
of the TDX series and improves upon
them with enhanced performance,
superior ride quality, quieter chassis
and an elegantly simple design.

The Invacare® TDX® SR wheelchair
builds off of the proven Invacare® TDX®
SP platform and offers the benefits of
Invacare® Gearless Brushless GM™
TrueTrack motors. TrueTrack allows
the chair to maintain a more consistent
forward path with fewer veer corrections.
TrueTrack motors ultimately result in less
fatigue for those using alternative driver
controls, and those with impaired hand
function.
The TDX SR wheelchair offers the
same performance features of the
TDX SP wheelchair including:
• Enhanced Invacare® SureStep®
Suspension
• Quiet Stability Lock
• Contemporary Aesthetics
• Wider Rear Caster Spacing

Invacare® Gearless Brushless GB™ Motor.
Invacare® Gearless Brushless GB™ motors are not only
a key component of TrueTrack technology, , but the design
is also 75% efficient, resulting in 17% more battery
range than Invacare’s 4-pole motors. Battery range is
an important feature for active users and users requiring
powered seating systems.
TrueTrack Technology.
The patented TrueTrack technology features GB motors
and motor controller. This feature helps keep the power
wheelchair on a truer forward path – even on many
slopes, thresholds and uneven terrains. TrueTrack
minimizes the need for veer correction, diminishing
fatigue for joystick and switch drivers.
TrueTrack Technology is beneficial for the client for
the following reasons:
• As the power wheelchair holds a truer course, the
driver needs to make fewer course corrections.
This makes driving more efficient by reducing the
necessary amount of movement. Reducing the required
movement can increase overall speed (i.e. the client
may be able to move down a hallway faster, as less
compensatory movements are required), decrease
fatigue, and promote independence while driving,
because the chair is not pulled off course. This is
true for drivers using a proportional control as well
as a digital or non-proportional system.
• This feature is critical for clients who fatigue easily,
as less compensatory movements are required.
• This feature also is critical for clients who use a
non-proportional or digital access method (i.e. a
head array with proximity switches or pneumatic
sip-n-puff controls). Driving with switches can be
very tedious and inefficient. Making frequent course
corrections significantly increases the effort, time and
energy required. Fewer course corrections translates
to a more efficient driver.

14
The TDX SR wheelchair is available with the
adjustable rehab seat, captain’s seating and the full
range of powered seating options. The Invacare®
Formula™CG Powered Seating system offers up to
7" of weight shift tilt, a low starting seat to floor
height of 17.5", numerous back type options and six
combinations of tilt, recline and elevate including:
• Tilt only
• Recline only
• Elevating seat
• Tilt/Recline combination
• Tilt/Elevate combination
• Tilt/Recline/Elevate combination
The TDX SR wheelchair offers Smart Actuators
standard at no additional upcharge. Smart Actuators
allow the client to achieve a pre-set tilt, recline and
power leg extension through use of the Power
Center-Mount front rigging. An audible alarm
sounds to let the client know that it is time to
weight shift.

Transport Ready Options.*
Rear transport bracket.
The Invacare® TDX® Family offers a transport ready option
(TRRO) that includes four tie-down locations, a battery
securement system and a wheelchair-anchored pelvic belt.
The chairs with TRRO configuration have been crash-tested
in accordance with the ANSI/RESNA Vol. 1 Section 19.5.3
Frontal Impact Test (W/C 19).**
Invacare also offers the TRBKTS option. Unlike the TRRO
configuration, a chair with TRBKTS option does not have a
pelvic belt and it has not been crash-tested in accordance
with W/C 19 or any other standard. TRBKTS is intended to
secure an unoccupied wheelchair only.
These options reinforce Invacare’s market leadership in
transport-ready wheelchairs for consumers.
* As of this date, the U.S. Department of Transportation has not approved any
tie-down system for transportation of a user while in a wheelchair in a moving
vehicle of any type. Accordingly, Invacare recommends that wheelchair users
not be transported in vehicles of any kind while in wheelchairs and should be
transferred for transportation into appropriate seating in vehicles and use the
restraints made available by the auto industry.
