The Stair Stepper Power Chair Is A Revolutionary
Product Allowing A User To Climb Up & Down A Stair Way.
basic concept of the Chair Stepper By Top Chair-S ® stair-climbing
wheelchair is simple : it climbs stairs going backwards and
goes downstairs forwards, while the seat always remains horizontal
to ensure a safe and comfortable ride. This animated film will help
you better visualize just exactly how it works.
with the help of Chair Stepper, going up and down stairs with a
wheelchair is no longer a dream. A sophisticated system of infrared
monitors detects the first and last steps and positions the wheels
appropriately – completely automatically. Very easy to use, the
wheelchair uses a standard joystick and only requires pushing one
button to go into stair-climbing mode.
One of the many advantages of the Chair Stepper-S® stair-climbing
wheelchair is that it can, in most instances, be used without the
need for any modification of buildings, or for another person to be
there to help.
However, if the user is unable to operate the chair by themselves
for any reason, assistant controls can be installed to allow safe
and east operation by a third party.
The TopChair-S® climbs stairs going
backwards and goes downstairs forwards. The seat always remains
horizontal ensuring a safe and comfortable ride.
To Climb Stairs
Positioning the wheelchair at the base
of the staircase, press on the « Stairs Mode » button. The
system raises the front wheels and activates the caterpillar
track motors (the tracks are now resting on the floor).
Pulling the joystick backwards, the
system automatically detects the first steps and raises the rear
wheels. The wheelchair is now completely resting on the
caterpillar tracks. All the user needs to do in order to
continue climbing the stairs is to pull the joystick backwards.
When the wheelchair arrives at the top,
the system detects the last step and, in turn, lowers the rear
and front wheels to de-activate “Stairs Mode”.
To Go Downstairs
Positioning the wheelchair at the top
of the stairs, press on the « Stairs Mode » button. The system
raises the front wheels and activates the caterpillar track
Pushing the joystick gently forwards,
and when the center of gravity has gone beyond the edge of the
first step, the system automatically stops the wheelchair in
order to raise the rear wheels. When this operation is
complete, all the user needs to do to descend the stairs is to
push the joystick forward again.
When the wheelchair arrives at the
bottom, the system automatically stops the wheelchair and
lowers, in turn, the front and rear wheels.
Our Chair Stepper-S® wheelchair has an infrared detection system
on board that continuously checks the angle of the seat and adjusts
the actuators to ensure it is always horizontal.
The infrared system also checks the position of the wheelchair
relative to the axis of the stairway. When the wheelchair exceeds a
certain sideways angle, the system automatically halts the
caterpillar track causing the problem. By subsequently briefly
pushing the joystick forward, the system activates the appropriate
track and straightens the wheelchair.
Finally, this control system checks the speed at which the user
is going up or down the stairs. When the speed exceeds safe
operating limits, the system stops the caterpillar tracks,
indicating to the user he / she must slow down.

TopChair Has Both Brake Lights As Well As Turn Signals.
The Rear Lights Are

The Chair Stepper By Top Chair-S®
wheelchair can be used by any person with limited mobility (*)
who up until now has not been able to go out because of a few
steps in their way, in order to:
Go to work
Visit with family and friends
Go to school
Our client base is varied. People of
all ages, all backgrounds and with all types of handicap:
The teenager, handicapped from birth, who needs to go down five
steps in order to leave his house and go to school. There is not
enough room for a ramp.,
The diplomat, handicapped following an accident, who has 7 steps to
go up in order to reach his office. The building is a listed
building and the entrance cannot be adapted for handicapped access,
The worker, who has a degenerative disease and who lives on the
second floor without a lift, and who needs to get out to go to work,
The lawyer who must attend hearings in Court - a listed building
where handicapped access is impossible
None of these people could go around living their lives in this way,
without their TopChair-S®.
A Little Background
TopChair was born from the idea to build a wheelchair that is able
to go up and down stairs without any help from other people.
The initial concept was simple enough : to use rubber caterpillar
tracks to go up and down the steps, while keeping the seat in a
From this early concept, the fist prototype was developed with the
help of funding by a French Government agency, ANVAR. With further
help from the Paris Regional government and in partnership with the
Engineering School of Toulouse (L’ICAM), the design was able to be
finalized, tested and made ready for use by people with limited
mobility. The whole project began in 2002, when the company was
known as « HMC2Développement”.
With overall performance on the road comparing very favorably with
other powered wheelchairs on the market, TopChair is also,
currently, the only wheelchair capable of going up and down stairs
and steps without help from other people.
TopChair SAS has won a number of awards :
Tremplin Entreprises, co-organised by the French Senate and the
ESSEC business school
Fondation ALTRAN for Innovation
The OSEO-Anvar Prize at the International Innovation Show in Geneva
