Question 6644
In addition to being adjusted to the proper height, what gap should there be between the head restraint and the head for it to be effective?
- More than 10 centimeters.
- The largest possible, and never less than 5 centimeters.
- The smallest possible, and never more than 4 centimeters.
Show answer and explanation
Correct answer: The smallest possible, and never more than 4 centimeters.
The smallest possible, and never more than 4 cm. With your head close to it, the head restraint supports it as soon as it starts moving backward. With a gap of 5 or 10 cm, your head reaches it at a higher speed, putting more strain on your neck.
