FIELD OF THE INVENTION
[0001] The present invention relates to a footrest for a wheelchair, said footrest being
configured so as to prevent injuries of the user when he accidentally falls down and
violently hits said footrest.
BACKGROUND OF THE INVENTION
[0002] Conventional wheelchairs are commonly equipped with two footrests adapted to support
each foot of the person using the chair. Said footrests are mounted at the front of
the chair and on either side of the wheelchair seat so as to form a plane support
for the user's feet when he is sitting inside the wheelchair. Advantageously, each
footrest may be commonly equipped with a heel strap, said strap being configured to
support the heel of the user's foot. Said strap generally extends at the rear of the
footrest and in an orthogonal position with regard to the footrest plate. The strap
is generally received over one or several metallic posts fixedly connected to the
footrest plate and positioned near the corners of the footrest plate. Such a configuration
has been usually used in conventional wheelchairs for a long time. However, such a
configuration may constitute a danger to the user if he accidentally falls down from
the wheelchair and violently hits the footrests with his backside for instance. Indeed,
in this case, the probability is high that he is seriously injured by the metallic
posts of the footrests.
[0003] Surprisingly, despite this known danger for the user, no solution has been proposed
in the state of art to the above mentioned problem.
[0004] The aim of the present invention is therefore to provide a footrest for a wheelchair,
wherein the drawback mentioned of the known footrests is avoided.
SUMMARY OF THE INVENTION
[0005] In this view, the present invention is concerned with a footrest as claimed in claim
1.
Important features of the device are defined in the dependent claims.
[0006] With a footrest according to the invention, the probability that the user is seriously
injured when he hits the footrests is highly reduced. Indeed, in this case, when the
user hits the footrests, the flexible posts of said footrests are configured to bend
under the user's weight and, therefore, avoids that the user's body is pierced by
said posts.

Figure 2 is a perspective view similar to Figure 1 before the connection of the heel
support strap;
Figure 3 is a front view of a post used in the footrest of Figure 1;
Figure 4 is a longitudinal section of the post of Figure 3.
DETAILED DESCRIPTION OF EMBODIMENTS OF THE INVENTION
[0008] In reference to Figures 1 and 2, a footrest conform to the present invention is shown.
[0009] The footrest 1 comprises a footrest plate 2 defining an upper plane surface 2a adapted
to receive the foot of a user, said upper surface 2a having an approximately rectangular
form. The footrest plate 2 is connected at one of its lateral end 2b to the lower
end of a legrest 3 of the wheelchair. At two diagonally opposite corners of said footrest
plate 2 is positioned two posts 4 over which is telescopically received a heel support
strap 5. In the embodiment shown, the heel support strap 5 forms, at its respective
ends 5a and 5b, a loop configured to tightly lodge a post 4. Said strap 5 may be formed
from canvas, plastic, leather or other flexible material. Each post 4 is fixedly connected
to the footrest plate 2 by means of a screw 7 received inside a threaded hole 6 of
the footrest plate 2.
[0010] In reference to Figures 3 and 4, a post used in the footrest of Figure 1 is shown.
[0011] The post 4 comprises an upper part 4a and a lower part 4b. A threaded hole 4c is
formed in the lower end 4d of the upper part 4a so as to permit a screwing connection
between the lower part 4b and the upper part 4a. For similar reasons, a threaded hole
4e is formed in the lower end 4f of the lower part 4b so as to receive the screw 7.
In the embodiment shown, the upper part 4a has an approximately cylindrical form in
a middle area 4g comprised between the upper end 4h and the lower end 4d. The upper
end 4h of the upper part 4a has a hemi-spherical form that is defined by its circular
base 4i, the diamater d1 of said base 4i being greater than the diameter d of the
middle area 4g so as to form an abutment for the heel support strap 5 when said strap
5 is tightly received over said middle area 4g. In a preferred embodiment of the invention,
the difference between d1 and d will be comprised between 0,5 to 2 mm. In addition,
the lenght L of the upper part 4a will be advantageously comprised between 10 and
25 mm and will be 0,5 to 2 mm higher than the width of the heel support strap 5.
[0012] The post 4 is also configured so as to flex downwardly when someone exerts a vertical
pressure from top to bottom. Accordingly, the upper part 4a of said post 4 is advantageously
made in a flexible plastic material. Said material is also configured so as to be
sufficiently rigid to resist to lateral pulling efforts exerted by the user's feet
via the heel support strap 5. Advantageously, said material will have an hardness
comprised between 60 and 90 shore and will be chosen among polyurethan. In addition,
the lower part 4b of the post 4 is advantageously made in a rigid plastic material,
in particular in a polyamid with 30% glass fibres.

connected to said footrest plate (1) and one upper part (4a) made in a flexible plastic
material.
