Belt retractor, belt tensioner, belt tension limiter
First read and observe the introductoryinformation and safety warnings⇒
Introduction
The seat belts in the vehicle are part of the vehicle safety concept ⇒ Airbag system and include the
following important functions:
Automatic belt retractor
Every seat belt is equipped with an automatic belt retractor on the shoulder part of the belt. Full
freedom of movement is made possible when the shoulder belt is pulled slowly or when the vehicle
is travelling at normal speeds. However, if the belt is pulled out quickly or during sudden braking,
during travel in mountains or bends and during acceleration, the automatic belt retractor is locked.
Fastened seat belts on the front seats may be tensioned automatically by the proactive occupant
protection system in critical situations, for example during emergency braking or as a result of
oversteering or understeering. Both seat belts are slackened if the accident does not happen, or
when the critical situation has passed. The proactive occupant protection system is ready to be
triggered again ⇒ Proactive occupant protection system.
Belt tensioners
The seat belts for the front seat vehicle occupants, and in some cases those on the outer rear
seats, are equipped with belt tensioners.
The belt tensioners are activated by sensors during severe frontal, side and rear collisions. They
tighten the seat belts against the direction in which they are pulled. Any slack in the seat belt is
retracted, which can reduce the passenger's movement forwards or in the direction of the impact.
The belt tensioner works together with the airbag system. If the vehicle rolls over, the belt
tensioners will not be activated if the side airbags are not triggered.
A fine dust may be produced when the airbags are triggered. This is quite normal and does not
mean that there is a fire in the vehicle.
Reversible belt tensioning (proactive occupant protection systemyf
Reversible belt tensioning may trigger in certain driving situations. For example:
•Heavy braking,
•Oversteer or understeer,
•Minor collisions.
⇒ Proactive occupant protection system
Belt tension limiter
The belt tension limiter reduces the pressure exerted by the seat belt on the body during an
accident.
All safety requirements must be observed when the vehicle or components of the system are
scrapped. Qualified workshops are familiar with these requirements ⇒ Service and disposal of belt
tensioners.
Service and disposal of belt tensioners
First read and observe the introductoryinformation and safety warnings⇒
Introduction
Seat belts may become damaged during any work on the belt tensioners or while removing or
refitting any vehicle parts in conjunction with any other repair work. This damage will not always be
noticeable. The consequence may be that the belt tensioners could function incorrectly, or not
function at all, in the event of an accident.
Regulations must be observed to ensure that the effectiveness of the belt tensioner is not reduced
and that removed parts do not cause any injuries or environmental pollution. Qualified workshops
are familiar with these requirements.
Never adjust the seat belt height when the vehicle is in motion.
WARNING
Description and function of the airbags
First read and observe the introductoryinformation and safety warnings⇒
Introduction
The airbags can protect vehicle occupants during frontal and side collisions by reducing their
movement in the direction of the collision.
When an airbag is triggered, it is inflated by a gas generator. This causes the airbag covers to
break, and the airbags inflate forcefully to cover their deployment zones within milliseconds. Once a
vehicle occupant wearing a seat belt starts to sink into the inflated airbag, the gas inside the airbag
starts to escape to cushion the occupant and slow down their movement. This can reduce the risk
of severe and fatal injuries. A triggered airbag will not always prevent other injuries from occurring,
such as swelling, bruising, burning and grazing. The deployment of the airbag can also produce
frictional heat.
Airbags provide no protection for the arms or lower body. Exception: in vehicles with a knee airbag,
the knee area of the driver will be protected.
The most important factors for triggering the airbag are the type of accident, the angle of impact,
the vehicle speed and the type of object with which the vehicle collides. Therefore, visible damage
to the vehicle does not always mean that the airbag should have been triggered.
Whether or not the airbag triggers is determined by the vehicle deceleration rate caused by the
collision and registered by the electronic control unit. If this rate is below the reference value
programmed into the control unit, the airbags will not be triggered, even though the vehicle may be
badly damaged as a result of the collision. Vehicle damage, repair costs or even the lack of vehicle
damage in an accident do not necessarily give an indication of whether an airbag should inflate or
not. It is not possible to define a range of vehicle speeds and reference values, since the
circumstances will vary considerably between one collision and another. It is therefore impossible to
cover every possible kind and angle of impact that would trigger the airbags. Important factors in
the triggering of the airbag include the nature (hard or softyf R I W K H R E M H F W W K D W W K H Y H K L F O H K L W V W K H
angle of impact, and the vehicle speed.
Airbags only serve as a supplement to the three-point seat belt in some accident situations when
the vehicle braking is sufficient to trigger the airbags. Airbags can only be triggered once and only
in certain situations. The seat belts are always there to provide protection in situations in which the
airbags are not triggered or have already been triggered. For example, if the vehicle collides with a
further vehicle following the initial collision, or is hit by another vehicle.
The airbag system is part of the vehicle's overall passive safety concept. The airbag system can
only work effectively when the occupants are wearing their seat belts correctly and have assumed a
proper sitting position ⇒ Sitting position.
Components of the vehicle safety concept
The following vehicle safety equipment makes up the vehicle's safety concept to reduce the risk of
severe and fatal injuries. Some of this equipment may not be fitted in your particular vehicle. It may
not be available at all in some countries.
•Optimised seat belts for all seats.
