<VV> Seat lock data

[William Hubbell]

I cannot argue the point about shoulder harnesses - nor the caveat about “if installed correctly.”  

The problem is, we don’t have any data about how to correctly install them in any car for which they were never originally installed.  Shoulder harnesses went through many different designs in the early years of use, before they finally figured out today’s designs.   It might be a mistake to assume we could simply add them to an older vehicle and get good results without doing structural analysis of the proposed mounting points and how they might be affected by various crash scenarios.

There is a Holley carburetor book written by Bill Fisher and Mike Urich. In that book is a statement:
"If the results don't agree with your theory, believer the results and invent a new theory."

PS - "If installed correctly, shoulder harnesses are still a good addition."  - Seth Emerson

Interesting article - particularly their conclusions:

Indeed, no significant casualty reduction was found in the sled tests or any of the accident data files, in spite of the large samples of data analyzed and the strenuous efforts to avoid biases in the analyses. Positive results were not obtained for any seating position (front seat occupants with nobody sitting behind them, front seat occupants with somebody sitting behind them, back seat passengers) or any specific injury type. No benefits were found in frontal crashes, or for restrained occupants, or unrestrained occupants.

Also:

Summary
This preliminary evaluation analyzes numerous sled tests and over a million accident cases, but none of the data showed significant benefits for SBL...  the data make a strong case that SBL have little or no overall effect on fatalities and injuries.

Hi all,

In addition to being a great place for cat videos, the Internet offers quite a number of actually useful resources.  Specifically I direct your attention to:
