"Dear Mr. Odaira: This responds to your letter asking about the ne dynamic requirements of Safety Standard No. 214, Side Impact Protection. You noted that the rear seat requirements do not apply to passenger cars which have rear seating areas that are so small that the Part 572, subpart F dummies cannot be accommodated according to the specified positioning procedure. You asked whether a test dummy should nonetheless be placed on the rear seat of such vehicles when conducting the specified dynamic test. As discussed below, the answer to your question is no. Section S3 of Standard No. 214 includes the following language concerning the dynamic side impact requirements: Part 572, subpart F test dummies are placed in the front and rear outboard seating positions on the struck side of the car. However, the rear seat requirements do not apply to passenger cars with a wheelbase greater than 130 inches, or to passenger cars which have rear seating areas that are so small that the part 572, subpart F dummies cannot be accommodated according to the positioning procedure specified in S7. Reading these two sentences together, it is our interpretation that a test dummy should not be placed in the rear outboard seating position of passenger cars which have rear seating areas that are so small that the part 572, subpart F dummies cannot be accommodated according to the positioning procedure specified in S7. While the first sentence states that the test dummies should be placed in both the front and rear outboard seating positions on the struck side of the car, that provision is limited by the sentence which immediately follows. That second sentence makes it clear that the rear seat requirements do not apply to certain vehicles with small rear seating areas. Since the sole purpose for placing a test dummy in the rear outboard seating position is to measure compliance with the dynamic side impact requirements, a test dummy should not be placed in the rear seating position of a passenger car for which the rear seat requirements do not apply. I hope this information is helpful. If you have further questions, please contact Edward Glancy of my staff at (202) 366-2992. Sincerely, Paul Jackson Rice Chief Counsel";
