TITLE: FMVSS INTERPRETATION

TEXT: Thank you for your letter of October 2, 1972, concerning the Ford "Tot-Guard" and your child restraint patents.

The consumer complaints that we have received on the Ford Tot-Guard have been complaints focussing on the fit of the device for minimum recommended size children. The comments relate both to the case with which small children may climb out of the device and slide under it, as well as to the vision restriction problem for the small child.

The Tot-Guard has proven to perform well in 30 mph frontal impacts with the three-year-old child dummy in our research programs, but can be improved in lateral protection capability and in performance with the 50-pound child dummy.

We have just completed a research program to develop new concepts in child restraints and will very shortly be making these designs available for any manufacturer who chooses to produce one of these advanced design restraints.

A copy of your letter will be placed in the public docket along with plans for the restraints developed on our child restraint development contract.

We are interested in reviewing and placing in the public docket copies of your designs for the infant car bed, which you mention, in hopes of stimulating the production of a crashworthy design for such a device.

We appreciate your letter and are looking forward to hearing from you in the near future.

SINCERELY,

HEINRICH VON WIMMERSPERG DEVELOPMENT ENGINEER

OCTOBER 2, 1972

Douglas W. Toms Director National Highway Traffic Safety Administration

An article by John Thorner in the WASHINGTON POST on 20 July 1972, relative to the Consumers Union's report on children's car safety restraint systems, quoted you as stating that your agency, the National Highway Traffic Safety Administration, had found that children did not like the FORD "TOT-GUARD" and that therefore it would be difficult to get parents to use this restraint system.

As the owner of the basic patent used in the "TOT-GUARD", (Patent #3,232,665), I am naturally interested in your comments.

It is my impression that you are referring to the fact that the "TOT-GUARD" does have an extended front piece, covered by FORD's patent #3,424,497, which does interfere somewhat with the child's ability to see forward and may thus cause some children to object to being placed in the seat.

However from all dynamic tests about which I have heard, the FORD "TOT-GUARD" does provide maximum safety for children weighing up to 50 pounds in simulated crash conditions.

An editorial in the WASHINGTON POST of 6 July 1972, copy of which I am enclosing, did pose the question: "If some manufacturers can meet safety testing, why can't all of them?"

It is with this thought in mind that I would like to call your attention to the fact that FORD has a NON-EXCLUSIVE license on my patent and that I would be willing to license other manufacturers to avail themselves of its features on terms generally equivalent to the FORD agreement, involving a very nominal royalty.

I do feel that the small royalty should not deter them from using my patent to make their devices safer.

I have already noted that some attempts have been made to copy my system, but the endeavor to avoid infringement of my patent has not resulted in making their devices as safe as they would be if they had used my patent.

I realize that the NHTSA is not in a position to act as a "sales agent" for my patent but, in the mutual interest of promoting safety for children riding in cars, I do think it would be perfectly proper for you to at least call attention of manufacturers of child car restraint systems to the fact that my basic patent is available on a non-exclusive basis to any manufacturer for a very nominal royalty.

For your ready reference, I am enclosing a copy of U.S. Patent #3,232,665 issued on 1 February 1966.

I am presently in the process of developing a new version of a children's seat based on my Patent #3,232,665, for children up to 50 pounds weight, having no restricted frontal vision, conveniently adaptable to different sizes of children and collapsible for easy storage and transportation.

Recently a patent was allowed to me which probably will be issued in January 1973. This is for a Safety Seat for Infants (old enough to be seated).

Further, I have just filed a Patent Application for a CAR BED for infants too young to be seated. It is based on a completely new principle, which provides maximum possible protection, equally safe for short trips or for longer traveling.

These three developments thus cover the complete range from the newborn baby to the 50 pound child.

Having had over 30 years background in the development of automotic firearms, covered by over 60 patents, I have, since 1955, been interested in the difficult problem of decelerating fast moving vehicle occupants in crashes without injury, a problem very similar to the problems to be solved in the design of ornaments. This work has resulted in my obtaining patents for an Automotive Safety Belt and for a shock absorbing Sun Vison, automatically covering the impact area of the windshield.

I would be happy to give you additional information regarding any of the above-mentioned matters if you are interested.

I know that you primary interest is in promoting, SAFETY for all people riding in cars and airplanes. It is my sincere belief that I have contributed something to this cause, and I got particular satisfaction from seeing a display of photos on the fifth Floor of the NASSIF Building in Washington showing a little girl sitting in a "TOT-GUARD" and also the car in which she was riding when it was rolled over in a side-impact collision, without injuring the girl. I presume you have seen this display. If not, I am enclosing a copy of the display.

I look forward to hearing from you.

Heinrich von Wimmersperg
