3 Point Safety Belt: Unwin Safety Systems

New 2012 video about fitting and removing the 3 Point Safety Belt from Unwin Safety Systems, the leading maker of wheelchair safety systems. Below is a transcript of the instructions given in this training video.
Once the wheelchair has been restrained, it is critical that the passenger is secured separately.
Unwin Safety Systems 3 Point Safety Belts have separate lap and diagonal belts so that they can accommodate wheelchairs with fixed armrests.
All passenger restraints are secured into rail using the purpose designed ATF clip.
Position the occupant restraint with the inertia reel unit on the wall side of the vehicle nearest to the 3rd fixing point and the stalk to the aisle side for quick release in the event of an emergency.
To fit the occupant restraint, press down on the ribbed part of the ATF to locate into the rail and then push firmly towards the wheelchair until the yellow plunger locks into place.
Clip the 3rd point fixing into the cant rail, above the inertia reel. Unfasten the tongue and buckle.
Pull the black webbing upwards and unfasten the tongue from the red webbing buckle.
Position the black webbing to form the lap belt and insert the tongue into the buckle stalk.
Ensure that the lap belt lays low on the pelvis of the occupant, running close as possible over the hips on both sides.
Fit the red shoulder belt tongue into the third point fixing.
Position the red webbing to form the shoulder belt and insert the buckle into the tongue.
Adjust the height of the shoulder belt to clear the occupant's shoulder by approximately 25mm (1 inch).
To remove the occupant restraint, first release the red shoulder belt from the lap belt section, then from the third point fixing and carefully allow the shoulder belt to return to the retractor.
Disconnect the black lap belt from the buckle stalk on the aisle side and carefully allow the lap belt webbing to return onto its retractor
To protect the restraint system webbing, connect the shoulder belt buckle to the lap belt tongue above the opening of the retractor box.
Remove both the occupant restraint and the stalk from the rail and stow in a suitable location in the vehicle.
