  1. Driver EducationSection VI • Day 1 - Occupant Protection

  2. SOL DE 14 • The student will demonstrate an understanding of the proper use of vehicle occupant protection features and analyze how they reduce injury severity and increase collision survival a. Active restraint system b. Passive restraint system c. Child restraint system d. Highway safety design

  3. Objective • The student will • Understand the proper use of seatbelts, airbags, and child restraints

  4. Day 1 – Occupant Protection • Bell Ringer – #1 • 3 paragraphs 5 sentences each • Describe your experience riding in a car during braking and accelerating. What does it feel like to be a passenger in a car that suddenly stops? Suddenly accelerates? • Why do you think wearing safety belts is especially important in these situations? • Why is it important for all passengers in the car to buckle up? • What are some other features on a car that make it safer?

  5. Definitions • Active Restraint • Passive Restraint • Occupant • Head Restraints • Air Bags

  6. Topics Safety Belts Child Safety Seats Air Bags Other Structural Features Occupant ProtectionDMVM > 20-21Text > 120-122DOE PP > Module 8 & Module 9

  7. Safety BeltsDMVM > 20Text Book > 120 • Can double your chances of surviving a crash and more than double your chances of avoiding serious injury. • Reduces chances of being killed by 50% and reduces chance of serious injury by 70%.

  8. Safety Belt Clip

  9. Accidents have three separate collisions: 1.The vehicle collision, the car hits something. 2.The occupant collision, the occupant hits unsecured items inside the vehicle. 3.The organs of the body colliding with the skeletal system. Buckle up to guard against additional injury from a secondary collision or ejection from the vehicle COPY THIS SECTION

  10. Virginia Safety Belt LawsDMVM > 20 • Requires drivers and front seat passengers to use safety belts. • A driver transporting anyone through age 15 must make sure that the child is properly secured in a safety belt, booster seat or child safety seat no matter where the child is seated.

  11. Virginia Law for ChildrenDMVM > 21DOE PP > Module 8 • All children under age eight must be properly secured in a child safety seat or booster seat. • Safest if seated in back center seat • Infant seats/rear facing/birth to 20 lbs. • Use child seats up to 40 lbs. • Use booster seats up to 60 lbs.

  12. DO NOT WRITE THIS SLIDE Movement of Belted Occupant DOE PP> Module 8 31 MPH Crash Head = 1.9 ft. Chest = 1.3 ft. Pelvis = 1.2 ft.

  14. DO NOT WRITE THIS SLIDE Types of Child Safety SeatsDOE PP > Module 8 Booster Seats Rear Facing Infant Seat Over 40 LBS until age 8 Up to 20 LBS Forward Facing Child Restraints Up to 40 LBS

  15. Handout Adjusting Belts for Proper Fit Seat belts should be worn over the strongest skeletal bones Wear Lap Beltlow and snug across hips (pelvis) to avoid unnecessary internal injuries Wear Shoulder Beltover collar bone and chest (sternum) to avoid shoulder dislocation and rib cage damage

  16. COPY THIS SLIDE Additional Safety Belt ConcernsDOE PP > Module 8 • Keeping the seat back in an upright position avoids the submarine effect of the lower body in a frontal crash.

  17. Safety Belt Clip

  18. Air BagsDMVM > 20-21Text > 120 • They cushion occupants as they move forward in a front-end crash. • The air bag keeps the occupant’s head, neck and chest from hitting the steering column or dashboard. • Some vehicle’s have air bags that inflate in a side collision. • Air bags do not take away the need to wear safety belts.

  19. Video ClipWith & Without Side Air Bags

  20. Handout Air Bag in Steering Wheel • Raise seat or adjust steering wheel to direct air bag toward chest and not at the facial area • Adjust seat for a minimum 10-inch clearance between chest and steering wheel • Hand position should be at 8 and 4 • Avoid 10 and 2 hand position to prevent blow hole burns to hands and arms

  22. COPY THIS SLIDE Fatal Crashes 63% of people killed in accidents are not wearing seat belts

  23. Class Work #1Other Structural FeaturesText Book > 120 - 122 • Read Pages 120 – 122 • “What features protect you and your passenger from injury?” • - Answer Lesson 2 Review Question #2 (page 122) • * Make sure to write down all 9 features ANDexplain why these features are important in your opinion.

  24. Other Structural FeaturesText Book > 121 - 122 Answers to Lesson 2 Review Question #2 Make Sure your answers Match (EACH SHOULD HAVE AN EXPLAINATON) • Head Restraints • Door Locks • Childproof door Locks • Tempered Safety-glass windows • Impact-resistant Bumpers • Protective padding on the Dashboard and Roof • Energy-absorbing steering column

  25. DO NOT WRITE THIS SLIDE Other Structural FeaturesDOE PP> Module 8 • Vehicle Crumple Zones • Anti-Lock Brakes • Traction Control Devices • Electronic Stability Program (ESP) • Suspension Control Devices • Headlights

  27. How Brakes Work Brakes are actually energy conversion devices. When you step on the brakes, they convert the kinetic energy (momentum) of your vehicle into thermal energy (heat). Thousands of pounds of pressure are applied on each of the four brakes, permitting the driver to slow or stop the rotation of the tires. The friction of the tires against the road surface will then slow and/or stop the vehicle. DO NOT WRITE THIS SLIDE DOE PP> Module9 Vehicle Systems —Brake Systems

  28. Topic 2 Lesson 1 Vehicle Systems —ABS Brake System Handout DOE PP> Module 9 Anti-Lock Braking System (ABS) * ABS was developed to assist driver braking actions by preventing tires from sliding and to keep them rotating slowly to allow steering.

  29. DOE PP> Module 9 Handout ABS Advantages Enhanced Braking Action • Enhanced Vehicle Steerability Braking and Steering In many emergency situations braking alone may not prevent a collision. • IncreasedVehicle Stability • ReducedStopping Distance

  30. DOE PP> Module 9 Handout With ABS… • Increase your following distance in bad weather • Practice using ABS • Keep your foot firmly on the brake even if it vibrates • Check owner’s manual for special concerns INCREASE

  31. DOE PP> module 9 Handout With ABS, Do Not • Drive More Aggressively • Pump the Brakes 3. Steer Too Much 4. Be Alarmed by ABS Noise or Vibration

  32. Handout Highway Design FeaturesDOE PP> Module 8 • Wide clear shoulders and wide lanes • Rumble strips installed at the road edge • Redesign of median barriers • Traffic calming devices

  33. Handout Highway Design FeaturesDOE PP> Module 8 1-Breakaway sign support posts 2- New design guard rails with ends angled away from roadway and buried 3- Crash attenuators such as vinyl liquid or sand filled drums

  34. Handout Highway Design FeaturesDOE PP> Module 8 4-Protected left and right turn bays 5-Collector/distributor lanes on high speed, high density highways - separates slower moving entering/exiting traffic fromthe higher speed through traffic 6-Variable message signs alert drivers to weather conditions, construction, and traffic problems

  35. Class Work #23 paragraphs, 5 sentences each • Come up with TWO additional safety features, for either the car or the roadway and explain why your safety features should be used and how they are to be implemented. Work on until the end of the class
