For the past 60 years and counting, Bell engineers have researched the forces involved in crashes across a wide range of scenarios. Recent findings have concluded that brain injury received during an angular impact can be much more severe, due to higher strain on the brain’s tissue. MIPS addresses this strain by allowing the head to slide independent of the helmet for a few milliseconds. This critical moment of time helps to reduce the relative motion of the brain inside the skull, and can potentially reduce strain to the brain caused by angled impacts.
