Head protection for reducing angular accelerations

Protective headwear to accommodate linear forces in a linear direction and angular forces in an angular direction, the headwear comprising:

• an outer shell having an outer surface and an inner surface;
• an inner liner having an inner surface and an outer surface;
• the outer surface of the inner liner being adjacent the inner surface of the outer shell;
• a plurality of shear components each unitary and separated by a space;
• the plurality of shear components each comprise a closed bladder containing a liquid;
• the plurality of shear components independently managing compression and shear force characteristics of the headwear to decrease brain trauma resulting from high linear and angular acceleration during impacts to the headwear;
• the plurality of shear components including a first shear component at a forehead of the headwear, a second shear component at a crown of the headwear, a third shear component at a rear of the headwear, a fourth shear component at a left side of the headwear, and a fifth shear component at a right side of the headwear;
• wherein the fourth shear component and the fifth shear component each include a first closed bladder and a second closed bladder with the first closed bladder being adapted to fit on one side of a user's ear when the headwear is disposed on a user's head and the second closed bladder being adapted to fit on an other side of a user's ear when the headwear is disposed on a user's head.
