SEATBELT INSPECTION and DEFINITIONS.

LTSA regulations:

The regulations for Seatbelts are contained in the Land Transport Rule 32011 – Seatbelts and
Seatbelt Anchorages.
From this ‘Rule’ the inspection criteria for Warrant of Fitness Inspections makes up the VIRM.
This is the inspection manual for all aspects of Vehicle Inspections.

Inspection Criteria:
The Inspection items detailed overleaf are a summury for the requirements of the VIRM.

EXPLANATIONS:

Tongue and Buckle Assembly:
This is the locking mechanism for the securing the seatbelt.
It is vital that the locking mechanism is secure and operating correctly.

Retractor:
The retractor mechanism is often hidden out of site inside the body structure of the vehicle.
The retractor automatically recoils the seatbelt when it is disengaged. It is a mechanical
device and can wear out over time. It is very important that the seatbelt webbing fully retracts
continuously in a smooth operation.
The locking mechanism that prevents occupants from moving forward violently in an accident
or severe braking, is located inside the retractor unit.

Webbing:
Seatbelt webbing is a special polyester weave manufactured and tested to a specific
International Standard for use in motor vehicles.
Damage to the webbing can dramatically reduce the effectiveness of the seatbelt.
Small cuts, frayed edges and holes in the webbing can cause it to tear when put under load.
Badly fade webbing, caused by sunburn and UV exposure, can have it’s strength reduced by
up to 5o%.

Anchorages:
The seatbelt unit must be securely fixed to the vehicle. Loose fittings, rust or insecure mountings will fail under load.

Accident Dynamics:
In a frontal impact accident at 50 kph, the vehicle occupants’ are propelled forward against the seatbelt restraint system.
The force applied to the restraint system is equal to 30 times the occupants’ weight. At 70
kph, this force is 60 times the body weight.
The force is applied in an instant, and any defective parts of the seatbelt assembly or
anchorages could result in failure, causing occupants’ to be propelled forward into the
steering wheel, dashboard or through the windscreen.
It is vital that seatbelts are inspected regularly for damage and replaced when found to be defective.

WEBBING
The webbing should be securely attached to its end Pass
fittings and displaying no stretching or pulled stitching.
The webbing should be flat throughout its entire length Pass
Look for plastic burn marks, frayed stitching and any Pass
