Seat Belts
Even though car crashes are the number-one cause of foetal death related to maternal trauma, we haven’t even yet developed a seat belt that works for pregnant women. Research from 2004 suggests that pregnant women should use the standard seat belt, but 62% of third-trimester pregnant women don’t fit the standard seat-belt design.
​
Standard seat belts aren’t great for nonpregnant women either: apparently, in an effort to accommodate our breasts many of us are wearing seat belts ‘improperly’ which again, increases our risk of injury (another reason we should be designing explicitly female dummies rather than just smaller male dummies).63 And it’s not just a woman’s belly that changes in pregnancy: breast-size changes can also diminish seat-belt efficacy by affecting positioning. Here again, we find an example of a situation where we have the data on women, but are just ignoring it. Clearly what is needed is a wholesale redesign of cars using complete data, and this should be fairly simple since it’s not exactly hard to find women to model a test dummy on.
Even with all these gaps, the 2011 introduction of the female crash-test dummy in the US still sent cars’ star ratings plummeting. The Washington Post reported on the experience of Beth Milito and her husband, who bought a 2011 Toyota Sienna, based primarily on its four-star safety rating. But all was not as it seemed. The passenger seat, which Milito says she is likely to be sitting in when they are ‘out and about as a family’, had a two-star rating. In the previous year’s model, the front passenger seat (tested on a male dummy) had earned a top five-star rating. But the shift to female dummies revealed that in a front collision at 35 mph a female passenger had a 20-40% risk of being killed or seriously injured. The average risk of death for that class of vehicle, explains the, is 15%.
