Seat Belt Tensioners - Seat LEON Owner's Manual

The seat belts are equipped with an automat-
ic retractor on the shoulder strap. Full free-
dom of movement is permitted when the
shoulder belt is pulled slowly. However, dur-
ing sudden braking, during travel in steep
areas or bends and during acceleration, the
automatic retractor on the shoulder belt is
locked.
The automatic belt retractors on the front
seats are fitted with seat belt tensioners

Seat belt tensioners

How the seat belt tensioner works
During a frontal collision, the seat belts on
the front seats are retracted automatically.
The seat belts for the occupants in the front
seats are equipped with belt tensioners. Sen-
sors will trigger the belt tensioners only dur-
ing severe head-on, lateral and rear-end colli-
sions and only if the seat belt is worn. This
retracts and tightens the seat belts, reducing
the forward motion of the occupants.
The seat belt tensioner can be triggered only
once.
The seat belt tensioners will not be triggered
in the event of a light frontal, side or rear col-
lision, if the vehicle overturns or in situations
where no large forces act on the front, side or
rear of the vehicle.
Note
If the seat belt tensioners are triggered, a
●
fine dust is produced. This is normal and it is
not an indication of fire in the vehicle.
The relevant safety requirements must be
●
observed when the vehicle or components of
the system are scrapped. Specialised work-

Service and disposal of belt
tensioners
The belt tensioners are components of the
seat belts that are installed in the seats of
your vehicle. If you work on the belt tension-
ers or remove and install parts of the system
when performing other repair work, the seat
belt may be damaged. The consequence may
be that, in the event of an accident, the belt
tensioners function incorrectly or may not
function at all.
So that the effectiveness of the seat belt ten-
sioner is not reduced and that removed parts
