The four-way chest strap kit helps to addition-
ally stabilise the person sitting in the power
wheelchair. The four-way chest strap kit must
never be used as part of a restraint system for
transportation of the person in motor vehicles
for the disabled.
To close the four-way chest strap kit, connect all parts of
the belt buckle. The belt buckle must snap in place audi-
bly. Then, verify that the belt has locked by trying to pull-
ing it apart. The four-way chest strap kit should not be
too tight on the body. Objects caught under the belt can
cause painful pressure sores.
To increase the length of the belt, turn the buckle by 90°
and pull. To reduce the length of the belt, pull the over-
hanging belt end.
8.9.3 Headrest Mounting Kit (Standard Seat)
Another option is to have the power wheelchair equipped
with a headrest. For this purpose, the mounting kit
showed in figure 38 is required.

8.9.4 rear Bumper
Equipping the B500 power wheelchair with a bumper is
also an option (fig. 39).
