Bicycle helmets reduce the chance of certain injuries such as skull fractures according to various research. However, they are not designed to prevent other injuries such as concussions or traumatic brain injury. This is due to test regulations, which only test for high speed linear accelerations. In reality however, low speed as well as oblique impacts occur frequently. A design is proposed that adds an extra layer to the inside of the modern helmet. Four zones with impact absorbing cylinders are both able to absorb low speed linear accelerations by compression, as wells as angular accelerations (as a result of oblique impacts) by shearing.
