Load cells and car safety: why baby is best facing backwards
Published On: April 19 2018
There’s no doubt that child car seats have saved many babies and young children from serious injury in car crashes. Now a new study aims to resolve a vexing question for all parents: which is better in the event of a rear-end collision, front-facing or rear-facing?
“The CRABI 12-month-old and Hybrid III 3-year-old ATDs instrumented with head and chest accelerometers, head angular rate sensors, six-axis upper neck load cells, and a chest linear potentiometer (3-year-old only).”
“Rear-facing car seats support the head, neck, and spine of the child. They help to keep these vulnerable body regions supported and aligned during a crash. This is especially important for children under age 2, whose spines are not fully developed yet.”
Sit back and relax
The team’s findings are very reassuring for parents:
“We found that the rear-facing car seats protected the crash test dummy well when exposed to a typical rear impact. …. A lot of the crash energy was absorbed through the car seat interacting with the vehicle seat, so that reduced the amount of energy transferred into the occupant.”
You can see the test rig set-up (albeit briefly) in this YouTube news report:
Load cells for crash test dummies
Today’s crash test dummies can be fitted with a range of 4 and 6 axis load cells that are specifically designed to measure the forces on particular body parts and joints, such as the lower neck, femur, knee, shoulder, and spine. There is event a 12-axial load cell available for measuring forces in the sacroiliac joint in the pelvis.
