It started with a easy query: is there a option to verify seat belt security for pregnant bellies?
A Toyota group of 4 ladies and one man introduced an concept in late 2022 that was easy however highly effective: pregnant clients don’t at all times really feel they’re protected and safe when utilizing seat belts present in automobiles at present resulting from seat belts becoming in another way on pregnant our bodies. Could Toyota assist change that?
“The common misperception that seat belts aren’t safe for pregnant women surprised me,” mentioned Juliana Said, a physique design engineer at Toyota Motor North America (TMNA) R&D. “Some people were even avoiding using them. The idea was: can we help show that the designs are safe, while investigating areas for further enhancement?”
When Said and her colleagues began to have a look at the problem, they encountered surprising challenges. There was restricted analysis concerning the effectiveness of seat belts with expectant moms or their infants. Additionally, the aftermarket was stuffed with untested, unverified security units.
But the most important problem to beat is a widespread (and faulty) perception amongst pregnant ladies and their households that seat belts are unsafe for a fetus throughout a crash – and that perception is so entrenched that some expectant moms drive unbelted.
In reality, at present’s seat belts are protected for pregnant ladies. When correctly worn, statistics present that belted pregnant ladies are a lot safer in crashes than people who don’t put on them. But a false narrative has developed that they will hurt unborn infants in crashes.
Said and her group began to work with the corporate’s Collaborative Safety Research Center (CSRC) in Ann Arbor, Michigan. CSRC contracted with the University of British Columbia, which has entry to a specialised magnetic resonance imaging machine designed to map anatomies of all kinds of physique shapes in a seating place.

While pregnant ladies correctly sporting seat belts have higher outcomes than no seat belts, there are alternatives by new analysis to additional discover seat belt match for pregnant ladies, in accordance with Jason Hallman, senior analysis supervisor for CSRC. The heart and its analysis collaborators set concerning the activity of making the info that engineers can use to probably give you future designs.
“We design seat belts using standardized dummies and processes,” Hallman mentioned. “There’s no standardized dummy, no standardized tools available specifically for assessing pregnant occupant safety. Therefore, the industry doesn’t have a clear understanding of how future seat belts could better protect pregnant women or fetuses during a crash.”
Working with the info generated at UBC, CSRC will create a computerized, three-dimensional mannequin of pregnant our bodies. And not only one physique, however how totally different styles and sizes look, with detailed illustration of bones, the backbone, inside organs, and numerous physique tissues in several phases of being pregnant.
In the long run, the analysis venture might assist improve one among Toyota’s analysis achievements, the THUMS digital crash damage mannequin. THUMS is sort of a digital crash-test dummy, constructed from painstaking analysis on totally different sorts of human tissue and the way they react to crash forces.
The University of British Columbia analysis group is utilizing a novel type of MRI machine to create the digital, three-dimensional representations of pregnant drivers, mentioned Peter Cripton, director of the Orthopedic and Injury Biomechanics Group at UBC.
The analysis group devised a technique to scan individuals seated in a automobile place. There are two large plates three to 4 toes aside. The take a look at topic sits in an automotive seat. A smaller MRI system is moved a number of instances to sew collectively totally different views till there’s a whole physique picture. Researchers are taking a look at how seat belts work together with bones and inside organs.
Cripton mentioned that one of many nice strengths of working with Toyota is that it’s a safety-minded producer with substantial information about constructing protected merchandise for patrons.
“It’s really exciting to me about working directly with an automotive manufacturer,” Cripton mentioned. “We will publish this data together, and make it available to other injury biomechanics researchers, too. Toyota will do the work, but it won’t just be Toyota that gets the benefit.”
The pregnant-body analysis and fashions could make clear one other high matter amongst dad and mom: whether or not third-party units designed for pregnant ladies add a security profit. There are big pads to placed on high of the seat cushion, a specialised lap belt, and a type of metallic defend, for instance. These varieties of units could seem logical, however they’re not topic to the type of rigorous testing used for seats, belts, airbags, and different elements of the automobile’s inside. With higher info sooner or later, reminiscent of digital pregnant crash-test dummies, researchers will be capable to draw higher conclusions.
“That product may seem obvious to you, but it may not be compatible with the way your car works,” in accordance with Said.
