TITLE: FMVSS INTERPRETATION

TEXT: In reference to your August 3, 1973, petition for rule making pertaining to Standard No. 213, we require additional information on your harness release mechanism prior to reaching any decision on this matter.

Specifically, we require data on the amount of force required to open your release mechanism under the following conditions:

1. When the harness system is preloaded with the child body block to 45 pounds (according to the existing procedure in Standard No. 213);

2. When the harness system is preloaded to 45 pounds with a three-year-old Sierra child dummy (by pulling on the arms and legs of the dummy); and

3. When the child seating system with an actual child occupant is suspended upside down and when the harness system is not unloaded (pulling only on the latch mechanism without releasing the load on the harness).

Your cooperation in furnishing us this data will aid in resolving this matter.
