Problems solved by technology

This method of energy absorption has advantages and disadvantages; when the energy is absorbed by the destruction or deformation of the protrusion, it occurs either in a short period of time, thus doing little to attenuate the rotational acceleration experienced by the user's head and brain, or the lining Can tend to spin out another liner, reducing helmet stability

Abstract

A helmet is disclosed that includes an outer liner and an inner liner slidably coupled to an inner surface of the outer liner by at least one return spring. The outer liner includes an inner surface with inwardly extending shelves. The shelf includes a stop surface. The liner has an outer surface, an inner surface, and an edge connecting the outer surface to the inner surface. The edge faces the stop surface of the shelf. The inner liner is slidably movable relative to the outer liner between a first position in which the edge of the inner liner is in contact with the shelf of the shelf through a gap and a detent position. A stop surface separates a portion of the edge of the liner in contact with a portion of the stop surface of the shelf in the stop position.

Description

technical field [0001] Aspects of this document relate generally to helmets with integrated rotation limiters. Background technique [0002] Protective headgear and helmets are used in a variety of applications and across multiple industries, including in sports, athletics, construction, mining, military defense, and others, to prevent injury to the user's head and brain . Contact injuries to the user can be avoided or mitigated by using a helmet that prevents hard or sharp objects from directly contacting the user's head. Non-contact injuries, such as brain injuries caused by linear or rotational acceleration of the user's head, can also be avoided or mitigated by helmets that absorb, distribute, or otherwise manage impact energy. This can be done using multiple layers of energy management materials. [0003] Conventional helmets with multiple energy management liners are able to mitigate the transfer of rotational energy to the head and brain by facilitating and control...
