Owners manual

Annex A

Adjusting the center mass and the seat depth:

Center mass adjustment is very important. It will affect the stability of the chair just like the
force required to tilt the patient. Table 3 is for reference purposes only. It was established
according to the mass distribution of a defined manikin according to the (ISO 7176 – 11: 2012)
standard. This distribution is a representation of an average person for a specific weight. On the
other hand, the specific anthropometry can be very different, and the proposed table may not
adapt to it. In addition, the infra table considers that the patient interface is as defined in
52. Note that the distinctive needs of the patient, such as a recessed backrest, could change the
setting.
