I cannot see any way of doing that in a practical way. Furthermore to deploy them rapidly enough you need a method of explosive decompression which would in all likelihood be more dangerous than the fall it would be capable of protecting you from. Again - the problem is not the ABILITY to build something that would work - it's the ability to build something that people can accept and isn't more of a danger than the fall. |

I do not see it as an improvement on the typical skid lid, and it looks to me as if it could lead to even worse neck injuries. -- Andrew Chaplin SIT MIHI GLADIUS SICUT SANCTO MARTINO |

At the moment of impact, just call 911 [1] and the helpful crew [2] will inflate it for you. [1] motto: "When seconds matter, we'll be there in half an hour or so." [2] In many areas, each call response must include a police or sheriff squad car, a fire truck and an ambulance regardless of the nature of the problem. -- Andrew Muzi www.yellowjersey.org/ Open every day since 1 April, 1971 |

What would trigger inflation? It's not a joke, at least not to the people promoting it. Supposedly it's got accelerometers and electronics that distinguish between normal motions and impending impacts. However, I remember seeing one video showing the thing going off accidentally when a guy was simply putting on the jacket that contained the gizmo in its collar. Since it costs upwards of $200, that false alarm was pretty pricey. (I searched for the video but couldn't find it.) -- - Frank Krygowski |

The new "Body Bag", an all encompassing inflatable covering for the bicyclist which automatically inflates in the event of an accident will provide the cyclists with "all over" protection. Yes! Development of the Body Bag (tm) is proceeding apace and we will shortly be accepting pre-devolvement donations. Presently we are working on the problem of decelerating which, while not impinging on the safety of the bicyclist does present certain difficulties in impeding the trajectory and absorbing kinetic energy of the inflated Body Bag. However initial studies of a drogue type devise, while not complete to date seems to present a probable solution. We wish to include mention of The Michelin Tire Company who provided certain visual preconceptual assistance to the Body Bag development team. http://tinyurl.com/yasztdk9 -- Cheers, John B. |
