Unit: Safety RestraintsSafety belts, child restraints, airbags

The primary learning outcomes desirable from this lesson are as follows:

1) Become aware of the various restraint devices (both active and passive), their capabilities and limitations.

2) Understand how to properly use these restraints, and utilize appropriate safeguard measures for maximum effectiveness.

3) Understand the fallacies and excuses people commonly give for non-seatbelt use and the benefits of consistent habitual usage.

In the U.S. alone seatbelts save more than 10,000 lives a year and over 200,000 serious injuries.

If you are wearing a shoulder-lap belt during a crash, your risk of being killed is reduced by 50% and risk of serious injury by 70%.

A restraining device, consisting of anchored straps that buckle across the hips, to protect a seated passenger from abrupt jolts, as in a collision.

Nearly every state has laws requiring the driver and front seat passengers to wear safety belts.


Deaths of unbelted occupants have occurred at speeds as low as 12 miles per hour.

Active restraints requires the connection and adjustment.

Passive restraints operate without action by occupants.

• Adjust the seat to a comfortable upright position…be sure the belt is not twisted and the metal fittings snap into place.

• The lap belt should be worn across the hip bones. (including expectant mothers)

• It should never be positioned across the stomach or soft part of the abdomen.

• Adjust the shoulder strap so that it is comfortable and does not cross the body at or near the neck or face.

• The shoulder belt should go over the shoulder and across the sternum.

• The shoulder belt should go over the shoulder and across the sternum.

The newer safety belts feel so comfortable you may not think they work, but they do. Many belt systems are activated only when the vehicle stops suddenly. The belt has a tiny pendulum connected to a locking mechanism. In the event of a sudden stop, the pendulum activates the locking device, which keeps you firmly in your seat.

The first crash is the car hitting the wall. In only 1/10th of a second, the car is stopped.

...but nothing makes the people stop...they keep going...until something inside the car stops them, like the steering wheel or instrument panel or windshield.

Cuts, broken bones a crushed chest...the films show it all.

Looking closer in slow motion, what looked like one crash, was actually two crashes.

Since safety belts areproven to be

very effective…why do some people still not wear them?

If you wear safety belts, they prevent you from being thrown from a car in case of an accident.

In a crash, any unbelted passenger is a danger not only to himself but to the other people in the vehicle, as he can crash into them causing injury.

Wearing safety belts really helps. You can see how in this crash test film.

Just the simple act of buckling up.

Wearing safety belts holds you while the car takes the force of the crash.

Be sure all passengers in your car all buckled!

Be sure all passengers in your car are buckled!

“Thee dead in this vehicle...the girl is critical. They say the guy without the seatbelt did the damage.”

“This is Michael. Today he is going to hit his girlfriend so hard that she ends up with permanent brain damage.”

Safety belts are also your best defense against drunk drivers.

You are four times more likely to die in a car crash if you are not wearing your seat belt.

90% of the time child restraints are not properly installed.

Auto accidents are a leading cause of deaths in infants and children.

50% of those deaths could be prevented by child restraints.

The back seat is the safest place for a child to ride.

Car crashes are sudden and violent. Your arms cannot hold onto an infant or child during a collision. But a certified, correctly installed child restraint system can.

As a driver, make sure that ALL infants and children are properly secured in

certified child restraint systems.

This simulated crash at 40 mph shows that a real unrestrained child would have been seriously injured in such a crash.

At closer to true speed the violence of the impact is evident. Even a mother’s arms cannot protect her child.

In fact, her body may crush her child in speeds as slow as 25 mph.

Children should always be restrained in cars. For those tall enough the shoulder strap should be used crossing the chest. (not the neck)

When used properly they

do work.

Since their introduction it has been estimated that airbags have saved several thousand people.

Below is an illustration of a driver side airbag deployment. The first image is the airbag inflation, the second depicts the dummies contact with the airbag, and the third is the deflation of the airbag. This all takes place in about 30 milliseconds.

In fact the entire inflation/deflation cycle takes less than 1/2 second. The speed of the airbag inflating is around 200 MPH. The vehicle has not come to a stop at this point.

Airbags are designed to only deploy in frontal crashes.

Side airbags have also been developed and are currently available with certain models.

More relaxed position, better if airbag deployed …but this position can quickly become fatiguing.

What about this 9 and 3 hand position on the steering wheel?

4 and 8 is now recommended – this is the location of most hand holds on the wheel.

At least 10 inches

This will affordprotection in case

WHY?

Also if you have a tilt-wheel, tilt it so the air bag will

deploy toward your chest. (not face)

Children and air bags do not mix

Air bags could seriously injure or kill children who are sitting in the front seat…they should always be in the back seat buckled up.

Also short adults (the airbag should be aimed at the chest)…on some models optional switches are available to temporarily turn off the airbag. (check with insurance policy for conditions)
