ATTACHMT: MEMO DATED 7-7-83 TO BINICHI DOI FROM FRANK BERNDT, REDBOOK A24, NOA-30

TEXT: On January 12th, I asked you this question and was told to submit the question in writing.

This question is from NSK-Warner K.K. of Japan which is one of the safety belt manufacturers of Japan and for which I work as its representative in North America.

Attached sketches are: 1. One type of adjust tongue installed in Japanese automobiles; 2. Another type of same; 3. GM's tongue called "One way friction D ring". The second sheet shows the general arrangement of our seat belt system.

Our question is as follows:

Is it required by regulation(s) that a safety belt system with tension reliever (such as GM's window shade type) should have adjust tongue of Type 3 of attached sketches (one way locking)?

Your kind attention to this inquiry will be appreciated by us.
