After the correct height for the chest strap has been chosen, you must adjust the tension of the chest
strap. (Fig. 2 b).
The chest strap can be custom adjusted to each person. It needs to be snug enough to hold the torso
in position when standing, but not so tight that it restricts breathing or over restrains upper body
movement.
Begin with the client seated in the chair and engage the chest strap as described above.
The tension of the chest strap is simply a function of its overall length. The length is adjusted by
weaving the straps through the single and double buckles located (and affixed to) the tension straps of
the back upholstery.
WARNING! It is not possible to stand up in this device without the proper application of the
chest strap. Attempting to do so is dangerous and could result in injury. The height of the
chest strap must first be adjusted followed by tension adjustment.
