Seat Belts
The
modern seat belt was created by Nils Ivar Bohlin, a Swedish aircraft
engineer. Bohlin's invention - a three-point combination lap and
diagonal belt positioned across the pelvis and rib cage - has saved
thousands of lives since its introduction in 1959.
Today, most drivers and passengers use their seat belts every
time they enter their automobiles. Unfortunately, millions of other
vehicle occupants put their lives at risk by either not wearing
them or not wearing them properly.
Seat
belts combine Bohlin's strong three-point harness with a relatively
simple pendulum and ratchet mechanism that locks the belt in sudden-stop
situations. This design helps improve the comfort of belt wearers,
as it is not locked in position under normal operation.
As
with any safety system, however, seat belt performance is dependent
on proper use and fit. If it is not positioned correctly on the
occupant's body, it can fail to provide adequate safety in the event
of a collision or rapid deceleration.
Seat Belt Tips
Seat
belts...
- ...should always
be worn. Insist that your passengers do the same. One non-restrained
passenger can seriously injure others in the vehicle.
- ...help prevent
internal injuries by spreading the force of a collision across
two of the human body's strongest areas - the pelvis and upper
chest. To ensure the proper distribution of force, the lap belt
should be positioned across the upper thighs. Without this restraint,
your body would be thrown under the diagonal belt and into the
dashboard or steering wheel. The
diagonal belt should be positioned across the chest. Never slip
it behind your body as the lap belt alone cannot prevent you from
being thrown forward and out of the vehicle.
- ...should fit
snugly against your body. If it is too loose, you could be injured
by being thrown against the belt itself.
Additionally...
- If your seat
belts don't seem to operate correctly, or you cannot adequately
adjust them, return the car to a dealership or qualified repair
shop for assistance.
- If your vehicle
is fitted only with lap belts (pre-1974 models), contact a dealership
for an upgrade to a three-point harness. Aftermarket kits are
available for many vehicle makes and models.
