After A Century—Airbags For Cyclists?

The first US-made automobiles with airbags were introduced in the mid-1970s.  The pneumatic restraints became common about two decades later and mandatory in 1998. However, the innovation is just over a century old: In 1919, Harold Round and Arthur Parrott of Birmingham, England filed a patent, which was approved the following year, in the United States.

(Interestingly, the airbag’s inventors were dentists. If they’d marketed their device, it would’ve made a fun ad slogan:  The Round Parrott takes the bite out of crashes!)

It took another three decades, however, for someone to patent a version for use in automobiles. John W. Hetrick, an industrial engineer, came up with the idea of a bag that would inflate on bumper impact after working on Navy torpedoes. Unfortunately, he became one of many who didn’t profit from his work:  No auto company wanted to finance it, and his patent expired just before Ford installed it on a few experimental cars.

That leads me to wonder whether the product I’m about to describe had a similar fate. Evoc Sports of Germany has just introduced its Commute Air Pro 18.  




It’s a set of football-style shoulder pads designed to inflate within 0.02 seconds after an impact is detected. They are intended to protect a cyclist’s neck, shoulders, chest and collarbone—the last of which is the site of frequent and painful injuries. The sensor is activated by an electronic magnetic buckle on the waistband. It can be unbuckled so that the rider can bend over (say, to pick up his or her bike) without deploying the airbags. The bags themselves are re-usable but, after they are inflated, the CO2 cartridge will need replacement.

The device is contained in a backpack that has enough room for a laptop and more. When it reaches the market next year, it’s expected to go for 900 Euros (about $1065 at current rates). I hope that a.) the price comes down, b.) it’s as effective at preventing injuries as it’s claimed to be and c.) its inventor benefits more from it than John Hetrick did from automotive air bags.

By Another Name

We’ve all heard Juliet’s plea to Romeo: “A rose by any other name would smell as sweet.”

There are entire academic sub-disciplines based on a negation of that premise.  So, what I am about to describe is ironic to me, as someone who’s been in the academic world.

When I worked in bike shops, I was classified, and described myself, as an assembler or mechanic.  The same can be said for others who did that work.  The other bike shop employees in shops—usually the larger ones—were salespeople and managers.  In smaller shops, though, employees (and, sometimes, the proprietor) wore multiple hats. Nearly all of us learned on the job:  Little, if any, formal training was available.

That last facet of the industry is changing.  Organizations like the United Bicycle Institute hold training programs and camps.  And community colleges—most recently Northwest Arkansas Community College—have launched programs to prepare students for the bike industry.

What has brought about this development?  Well, I think that one reason is that bicycles are increasingly included in transportation and infrastructure planning.  No one can argue any longer that adult cycling is a passing fad or a recreational activity for the privileged.

I believe there’s another another reason why academic institutions are seeing that the bicycle is not just a way to get around campus or an option to fill a Physical Education requirement—and that preparing students for a career in the industry is a worthy endeavor.  You see, now colleges like Northwest Arkansas and Minnesota State College Southeast are training bicycle technicians.

Now, in a way I can understand the name change: There is more technology, not only in design, but also in making, assembling and repairing new bikes and components than there was when I worked in shops.

I have to wonder, though:  Would the trajectory of my life have been different if I’d been a bicycle technician?

Whose Orders Would I Have Followed?

Years ago, someone tried to convince me to join a rowing team--what we call "crew" in the States.

Up to that time, I'd rowed maybe a couple of times in my life.  She didn't see that as a disqualifier.  If anything, she said, my other athletic pursuits, including cycling, would help. "People don't realize how important the legs are in rowing," she said.

She had a point.  She'd spent a lot of time with the rowing team:  She was its coxswain.

And, as  inexperienced as I was with oars, I'd spent more time with them than she'd spent on a bicycle:  She'd never learned how to ride. 

Oh, perhaps I should mention that we were dating.

I politely declined.

Our relationship didn't last much longer.

What if I had followed her "suggestion"--or she had learned how to ride?
