Seating System
The wheelchair has been tested for seating in a motor vehicle with
the factory installed seating system only.
Ensure that the factory installed seating system is secured to the
wheelchair frame before operation. Refer to the seating system user
manual.

Positioning Belts
Preferred Zone
Optional Zone
The angle of the pelvic belt should be within the preferred zone of 45
to 75 degrees to the horizontal OR within the optional zone of 30
to 45 degrees to the horizontal.
Steeper side-view pelvic belt angles are especially important if the
pelvic belt is intended to be used for postural support in addition to
occupant restraint in a frontal crash. Steeper angles will reduce the
tendency for a vertical gap to develop between the user and the
belt due to compliance of seat cushions and belt movement, thereby
reducing the tendency for the user to slip under the belt and for the
belt to ride up on the soft abdomen during normal use
Steeper belt angles also reduce the tendency for upper-torso belts to
pull the pelvic belt onto the abdomen during frontal impact loading.
