Seats and Restraints 3-27
{WARNING
A safety belt that is not properly
worn may not provide the
protection needed in a crash. The
person wearing the belt could be
seriously injured. The shoulder
belt should go over the shoulder
and across the chest. These parts
of the body are best able to take
belt restraining forces.
4. Buckle, position, and releasethe safety belt as described
previously in this section. Make
sure the shoulder portion of the
belt is on the shoulder and not
falling off of it. The belt should
be close to, but not contacting,
the neck.
To remove and store the comfort
guide, squeeze the belt edges
together so that the safety belt can
be removed from the guide. Slide
the guide onto its storage clip on the
interior body.
Safety Belt Use During
Pregnancy
Safety belts work for everyone,
including pregnant women. Like all
occupants, they are more likely to
be seriously injured if they do not
wear safety belts.
A pregnant woman should wear a
lap-shoulder belt, and the lap
portion should be worn as low as
possible, below the rounding,
throughout the pregnancy.
The best way to protect the fetus is
to protect the mother. When a safety
belt is worn properly, it is more likely
that the fetus will not be hurt in a
crash. For pregnant women, as for
anyone, the key to making safety
belts effective is wearing them
properly.
