Occupant Classification System (Ocs); Window Curtain Air Bags - Mercedes-Benz C-Class Operator's Manual

Window curtain air bags

Window curtain air bags : are integrated
into the side of the roof frame and deployed in
the area from the A-pillar to the C-pillar.
When deployed, the window curtain air bag
enhances the level of protection for the head.
However, it does not protect the chest or
arms.
In the event of a side impact, the window cur-
tain air bag is deployed on the side on which
the impact occurs.
If the system determines that they can offer
additional protection to that provided by the
seat belt, a window curtain air bag may be
deployed in other accident situations
( page 56).

Occupant Classification System
(OCS)
Introduction
The Occupant Classification System (OCS)
categorizes the person in the front-passenger
seat. Depending on that result, the front-
passenger front air bag is either enabled or
deactivated.
The system does not deactivate:
the side impact air bag
R
the window curtain air bag
R
the Emergency Tensioning Devices
R
Occupant safety
Prerequisites
To be classified correctly, the front passenger
must sit:
with the seat belt fastened correctly
R
in an almost upright position with their
R
back against the seat backrest
with their feet resting on the floor, if possi-
R
ble
If the front passenger does not observe these
conditions, OCS may produce a false classi-
fication, e.g. because the front passenger:
transfers their weight by supporting them-
R
selves on a vehicle armrest
sits in such a way that their weight is raised
R
from the seat cushion
If it is absolutely necessary to install a child
restraint system on the front-passenger seat,
be sure to observe the correct positioning of
the child restraint system. Never place
objects under or behind the child restraint
system, e.g. cushions. The entire base of the
child restraint system must always rest on the
seat cushion of the front-passenger seat. The
backrest of the forwards-facing child restraint
system must, as far as possible, be resting on
the backrest of the front-passenger seat.
The child restraint system must not touch the
roof or be put under strain by the head
restraint. Adjust the angle of the seat back-
rest and the head restraint position accord-
ingly.
Only then can OCS be guaranteed to function
correctly. Always observe the child restraint
system manufacturer's installation instruc-
tions.
