The Spex Seating System has been successfully crash tested and complies with RESNA WC-4:2012, Section
20 (WC20). 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 D. The
following items of the Spex Seating System have been tested and are suitable for use in a motor vehicle:
• Full Height Back Support Models
• Seat Base
• Cushion Models
• Arm and Thigh Supports
• Trunk Lateral Supports
• Head Supports
Note: Back supports that are lower than the user’s shoulder height are not certified and not recommended
for transport in a vehicle. Eg. Vigour Lo and Vigour Mid back supports.
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 Base
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 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. Spex Seating 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.
