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.

Safety check List

TONGUE and BUCKLE ASSEMBLY
Check the engagement of tongue and buckle          Pass

The tongue and buckle should securely latch          Pass
together with very little free play.

The tongue should eject actively when released     Pass

There should be no visible cracks on the buckle    Pass
and the buckle cover must be intact.

The tongue should have no metal deformation      Pass
webbing marks or visible cracks on metal or
plastic sections.

RETRACTOR
Pull the belt out as far as it will go, then release it. Pass 
The belt should return all the way to the retractor   Pass
Without sticking, gripping or stalling.

The retractor should lock if the webbing is pulled  Pass
out suddenly.

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
signs of rippling.

Look for fading – exposure to sunlight can reduce the    Pass
strength by up to 50%.

ANCHORAGE

Ensure all anchorages are free from corrosion and are Pass
securely fastened to the vehicle structure.

All mounting points should not show any signs deformation. Pass


Reports:
Everything is good condition nothing wrong .
