3-6. THE KNEE SUPPORT AND SAFETY BELT AND CHEST BELT
The most important safety features of the stand-up wheelchairs are the knee support &
safety belt and chest belt. It is absolutely essential that these be correctly in place before
you attempt to stand up.
3-6-1. THE KNEE SUPPORT
The knee support holds the knees in an extended posture and prevents you slipping out the
wheelchair while standing up.
Attach the two triangular form of the knee lock
support to the double-head screws on either side of
the wheelchair.

Center the knee support in front of each knee using
the Velcro fasteners, then pull it until it is sitting
firmly in place, just below the knee cap.
