TITLE: FMVSS INTERPRETATION

TEXT: This is in reply to your letter of November 21, 1973 to "U.S. Bureau of Safety" expressing your view that "the automobile industry should . . . have some type of clutch to reverse action when the closing motion of the (power) window meets any resistance."

I enclose a copy of Federal Motor Vehicle Safety Standard No. 118 Power-Operated Window Systems which has applied to all passenger cars and multipurpose passenger vehicles with power windows manufactured since February 1, 1971. The objective of the standard is to minimize the likelihood of injury or death occurring when a person is caught between a closing window and its frame, channel, or seat. The NHTSA determined that the most cost-effective way to accomplish this objective was by prohibiting operation of power windows when the ignition key is either in the ignition "off" position or removed. As you will see from the enclosure, consideration was given to mechanisms that would reverse the direction of the window.

We appreciate your interest in motor vehicle safety.

ENC.

The circumstance and comment in your letter of November 21, 1973, regarding automatic window closing operation is noted. The matter is deemed to be in the jurisdiction of the U. S. Department of Transportation (DOT). Therefore, we are forwarding your letter with a copy of this acknowledgement to DOT for their attention and an appropriate reply.

Gentlemen:

Recently one of our young patients was brought in after having his head caught in the window of a car door after the automatic window closing operation had been started. Fortunately, this was not a serious accident; however, it could have been.

It seems the automobile industry should be prevailed upon to have some type of clutch to reverse action when the closing motion of the window meets any resistance.

Sincerely,

IRVIN JACOBS, M.D.
