Dynamic Chest Harness
The Dynamic Chest Harness is made from
neoprene with soft edge binding which
allows the harness to stretch in response to
movement. This provides comfort and support
whilst not restricting active positioning. The
main body of the harness should be positioned
so that the bottom edge is level with the lower
edge of the rib cage. Four straps attach the
body of the harness to the chair. The lower
straps have multi-direction buckles which
swivel to follow the direction of pull to the
mounting point to avoid twisting and provide
comfort. The Dynamic Chest Harness is
designed to be used in conjunction with a
pelvic belt.
Dynamic Sternum Harness
The Dynamic Sternum Harness has the same
features as the Dynamic Chest Harness but
has a more incised profile for greater comfort
across the chest.
Adjusting the Harnesses:
Harnesses need to be positioned high up on
the chest to act against the rib cage. Ensure
the harness clears any abdominal implants.
