TITLE: FMVSS INTERPRETATION

TEXT: This is in response to your letter of March 9, 1973, requesting our confirmation of an opinion given you by phone concerning the method of testing the sensitivity of seat belt warning systems under Motor Vehicle Safety Standard No. 208.

We hereby confirm our previous statement that the weight sensing provisions of sections S7.3 and S7.4 do not require the use of a specified test dummy. The sections refer to "persons" of specified weights, thereby implying some distribution of the weight, but they do not reference the test dummy used in other sections of the standard.
