My final project presentation for my Mechanical Manufacturing course. The part is a removable bumper for wheelchairs that can be used to protect patients with fragile leg injuries.

2. Individuals with broken legs may have
difficulty navigating in wheelchairs
immediately after their injury. Improper
navigation in their wheelchair can result in
a collision, causing further damage to their
already fragile injuries.

3. A bumper device that replaces the axle of
a wheelchair.
*Note: The wheels are simply for reference, the original
wheels from the wheelchair will be used. As such, the wheels
will not appear in the following technical drawings.

4.  Manufactured by
Invacare Corporation
 Common, Lightweight,
and relatively
inexpensive
 Adjustable for multiple
seat widths and
depths
