Proper Restraints Save Lives!
Step1
With your child sitting in the chair, fasten a belt around her and the chair at waist level. Now, tell her that the original intent of the lap belt was to keep the passenger’s body from sliding forward and slamming the dashboard. Hold up the cutting board at chest level about a foot in front of her and ask her to bend forward, simulating her movement in a crash. She will quickly see why lap restraints were modified to include shoulder restraints.
Step2
Now remove the first belt, take the second belt or strap and lay it over your child’s left shoulder. Fasten it around the right side of the seat where the two right legs meet by the hip. Have your child try to repeat the forward motion. He will now see the value of the shoulder restraint, but his hips will slide forward, creating a submarine or hangman effect.
Step3
Now refasten the lap belt and repeat the process. Your child will now see the value of the three point restraint system, as no part of her body will slide forward or impact the dashboard. She will also be able to maintain control of the wheel, since she would not be bounced out of the driver’s seat.
Step4
Contrary to popular belief, the head rest is not merely a place to rest your head. The head rest is a safety feature and it is adjustable. Have your child tip his head back, simulating a reaction to a rear end collision. This motion will cause whiplash at even low speeds. Place the cutting board surface flat against the back of his head. Explain that the head rest should be high enough to keep the head from snapping back. Have him try this now. He will now see the value of the head restraint.
Step5
Explain to your child that the airbag is a tightly packed fabric balloon in the steering wheel. The airbag has sensors that set off a gas charge when they detect a strong enough collision. This gas charge has the force of a hard-swung baseball bad as the airbag leaves the steering wheel, but when the airbag inflates it is a much softer and less powerful blow.
To demonstrate this effect, have your child remove the restraint belts. To simulate an airbag deployment without seatbelts, have your child bend forward toward the baseball bat you are now holding. Suggest strongly that she try it faster this time, as you wind up to take a swing. Now ask her if she would prefer a cold, hard baseball bat or a big, fluffy pillow. She will now see the value of airbags when used properly with safety belts. This is a graphic demonstration, but it will certainly open the eyes of the invincible teen in your life.
