- d. Advanced Side Impact Support
Correct

Incorrect
Question 3 of 10

3. Question
According to the IIHS, lap belt fit should:
- a. lie flat and on top of the thighs
- b. rest on the pelvis
- c. sit high up on the abdomen
- d. None of the above
Correct

Incorrect
Question 4 of 10

4. Question
In the 2008 UMTRI studies, “Assessing Child Belt Fit, Volume I and Volume II,” the shoulder belt should:
- a. Rest on the shoulder
- b. Cross the clavicle
- c. Lay next to the neck
- d. All of the above
Correct

Incorrect
Question 5 of 10

5. Question
According to IIHS statements about shoulder belt fit:
- a. The shoulder belt should fit snugly across the middle of the child's shoulder
- b. If the shoulder belt falls off the shoulder or rests on your child's neck, it won't work as well as when it is properly fitted
- c. An improper fit could encourage the child to move the belt to a dangerous position, such as behind the back or under the arm
- d. All of the above
Correct

Incorrect
Question 6 of 10

6. Question
The simplest definition of submarining is “when the lap belt penetrates the abdomen”
- True
- False
Correct

Incorrect
Question 7 of 10

7. Question
According to the 1975 research by Adomeit and Heger, the Alpha angle is the angle between the H-S plane (the line from the hip to the shoulder) and horizontal plane
- True
- False
Correct

Incorrect
Question 8 of 10

8. Question
With heightless booster seats, “torso arching” does not indicate submarining, even though the Alpha angle is greater than 90 degrees because:
- a. The Beta lap belt angle is more acute than in a no-booster situation. The Beta lap belt angle is defined as the angle between the lap belt (running from the anchor point to the pelvis/abdomen) and the horizontal plane
- b. The Gamma lap belt angle is more acute than in a no-booster situation. The Gamma lap belt angle is defined as the angle between the tangent to the iliac crest and the horizontal
- c. All of the above
Correct

Incorrect
Question 9 of 10

9. Question
The most accurate method of measuring abdominal penetration by the lap belt during submarining is:
- a. Careful review of video crash test footage in ultra-slow-motion and high resolution
- b. Inserting a symmetrical block of soft clay on the inside of a crash dummy's spine, behind the abdominal insert
- c. Using fluid filled Abdomen Pressure Twin Sensors
Correct

Incorrect
Question 10 of 10

10. Question
In the 2017 CChIPS research project, “Efficacy of booster seat design on the response of the Q6 ATD in simulated frontal sled impacts,” the highest resultant upper-neck force was observed with which type of booster seat?
- a. No booster
- b. Inflatable boosters
- c. Heightless boosters
- d. Backless boosters
- e. High-back boosters
Correct

Incorrect
