Design & Testing

To ensure complete safety, Koller products are tested to the latest European and International Standards. All products are manufactured strictly in accordance to ISO 9001:2015. All testing is carried out at recognised independent test houses, such as MIRA, STATUS, TRL, TUV and where appropriate, VCA approved.

Wheelchair & Wheelchair Occupant Restraints

Koller webbing restraints feature quick-action securing mechanisms for easy operation and quick release in the event of an emergency. For maximum security, “closed-end” fittings are employed as standard, preventing any possible detachment of the restraint from the wheelchair.


  • ISO 10542 dynamic (crash) test, 85kg surrogate wheelchair, 76.3kg dummy, 20g at 48km/h.
  • ISO 7176 part 19 dynamic test, as above but with a specific wheelchair.

Koller restraints are often tested in excess of ISO 10542 test – see maximum wheelchair weights under each product. Components conforming to UN/ECE regulation No.16 are used in the manufacture of webbing restraints.

Removable Seat Fixings

Koller removable seat fixings have been tested with a diversity of seats, both on test “rigs” and in-vehicle. All removable seat fixings feature easy to operate locking / anti rattle mechanisms. A safe seat installation is achieved while retaining the easy ability to alter the vehicle layout.


ECE 14.04 and EEC Directive 76/115 as amended by 96/38/EEC or 2005/41/EEC, to M2 and M1 loads:

  • M2 load: 13.5kN + (10 x seat mass)
  • M1 load: 27kN + (20 x seat mass)

Note: The above loads are for forward facing seats with integral lap and diagonal belts.


Koller rail forms the basis to configure a vehicle’s seating layout, by allowing the easy fitting and removal of seats and wheelchair restraints. Koller rails are used when Seat Fixings and Wheelchair / Wheelchair Occupant Restraints are tested to the above test standards. Low Profile rail is the most commonly used rail and sometimes this is used in conjunction with VFS rail. These rails are therefore compliant with EEC Directive 76/115 (as amended) and / or ISO 10542 / ISO 7176 part 19.
