The Grip parameter defines the overall effect of the
Chair Stability Parameters (see
section 5.3.7.18).
The Chair Stability Parameters are used by the powerchair manufacturer to
• provide a stable chair
• prevent the drive wheels from slipping.
The powerchair manufacturer sets up the Chair Stability Parameters so that the chair is
stable an a flat surface with good physical grip.
For each Drive Profile, the dealer or therapist can use the Grip parameter to indicate to
the DX System the kind of surface that this Drive Profile will be used in. If the intended
surface offers little physical grip, the value of the Grip parameter can be decreased.
A low value of Grip increases the effect that the Chair Stability Parameters have, so the
chair will become more stable on that surface with little physical grip.

Maximum stability needed
Physical grip is the amount of contact that the drive wheels have with the surface
that they drive on. With little physical grip the drive wheels slip easily. If the wheels slip,
the powerchair is uncontrollable.
For example:
• A chair on a non-slip surface has a high physical grip,
so the Grip parameter can be set to 100%.
• A Rear Wheel Drive chair on a slippery surface has a low physical grip,
so the Grip parameter must be set lower.
Note:
For indoor Drive Profiles, set Grip to a low value to prevent skid marks
on the floor.
Warning:
The correct value for the Grip parameter is dependent on the value
of the Chair Stability Parameters (programmed by the powerchair
manufacturer). Testing is
required to verify suitability for individual
chair designs and/or users. See also section 7.4:

testing a DX chair for stability
