Abstract: An impact-absorbing helmet for reducing brain trauma includes an inner shell and an outer shell. The inner shell has a bottom and a front that are open. The bottom is configured to insert a head of a user, positioning the front proximate to a face of the user. The outer shell is complementary to and positioned around the inner shell. The outer shell has an edge that is coupled to a rim of the inner shell so that the inner shell and the outer shell define an interior space. A plurality of first springs is positioned in the interior space. Each first spring is coupled to and extends between the inner shell and the outer shell. The first springs are configured to reduce transfer to the inner shell of a force applied to the outer shell.
