WWW.SPEXSEATING.COM
The Spex seating system has been successfully crash tested and complies with RESNA WC-4:2012,
Section 20. The Spex seating system meets the requirements of ISO 16840-4:2009 and is suitable
for use as a motor vehicle seat when used with an appropriate wheelchair base. Please follow all
installation, use and maintenance instructions within this manual as well as the following transit
instructions. If feasible, the wheelchair user should transfer to the vehicle seat and use the vehicle-
installed occupant restraint systems.
Spex seating system has been designed to accommodate the proper use of vehicle-anchored belt
restraints. Spex achieved a rating of Excellent (16 out of 16), for ease of properly positioning a belt
restraint, and the degree to which proper belt restraint can be achieved, based on the methods of
Annex C.
The following items of the Spex seating system have been tested and are suitable for use in a motor
vehicle:
•
Full height back support range
•
Grid-Base Seat Pan

Note: Back supports that are lower than the user’s shoulder height are not certified and not

Assembly, Use, Maintenance & Limitations
•
Adjustments to the set up of the wheelchair must only be carried out by a qualified therapist,
professional, or seating technician. Custom contoured/bespoke systems may require a qualified
professional to configure and install the seating system.
•
After carrying out any adjustments ensure all bolts, screws and nuts are securely fastened again
to ensure safety when travelling in a vehicle.
•
Ensure the top and bottom mounts of the backrest and the front and rear mounts of the seat
pan are installed as far apart from each other as possible to give a stronger 4-point attachment
to the wheelchair frame. Ensure the quick release latches are engaged.
•
Do not use the Spex seating system as a means of vehicle seat if seating components which
have not been successfully crash tested are used anywhere on the seating system. Spex seating
is designed and certified using only Spex components. Medifab is not liable in the event where
other manufactured seating systems are used in conjunction with Spex seating.
•
At regular intervals check that all the fastenings on the Spex seating system have not become
loose during day to day use and re-tighten if necessary.
•
Ensure the swing-away laterals are in their locked position before using the seat as a vehicle seat
in a motor vehicle, if fitted.
