1.14 Visual inspection of buckle
– Examine the buckle for cracks and flaking.
• If damage is found, replace the seat belt complete with the
buckle.
1.15 Functional test of buckle
Checking buckle
– Insert the latch plate in the buckle until it is heard to engage.
Pull firmly on the webbing to check whether the locking mech‐
anism has engaged.
• If the latch plate fails to engage properly in the buckle even
once in the course of a minimum of 5 tests, replace the seat
belt complete with the buckle.
Checking release function
– Release the seat belt by pressing with a finger on the buckle
button. If the webbing is slack, the latch plate must be released
automatically from the buckle.
• Carry out the test at least 5 times. If the latch plate is not re‐
leased even just once, replace the seat belt complete with the
buckle.
WARNING
Never use lubricants to eliminate noise or if the buckle buttons
are stiff.
1.16 Checking guide fittings and latch plate
After being subjected to load (seat belt fastened in an accident)
plastic-covered fittings of the belt system exhibit fine parallel scor‐
ing marks (on the other hand, wear caused by frequent use can
be seen from uniformly smooth patches).
– Examine for deformation, flaking and cracks in the plastic.
• If scoring and/or damage is found, replace the seat belt com‐
plete with the buckle.
1.17 Checking fastening elements and an‐
chorage points following an accident
♦ Latch plate deformed (strained)
♦ No height adjustment function
♦ Anchorage points (seat, pillar, vehicle floor) deformed or
thread damaged
• If component damage is found, replace the seat belt complete
with the buckle.
• If parts of the belt system are removed on account of an acci‐
dent, the belt system bolts are to be replaced.
• Replace anchorage points.
Note
In the event of damage not resulting from an accident (for exam‐
ple wear) only the corresponding damaged part is to be replaced.
