Benefits of technology

The present invention is a device that reduces the angular acceleration of the head during a concussion impact by connecting helmet and shoulders. It is made with a special fluid that dampens the impact load transfer to the body, minimizing brain injury. The device is designed to not interfere with the normal movement of the head and is conformal to the body. The key component is a fluid that shows a sudden solidification and quick refluidization upon stress. This technology is unique and can be used in a multi-degree-of-frequency damper to prevent brain concussion for football players.

Problems solved by technology

Most existing literature has focused on the periodic or quasi-steady response of such fluids and appropriate models and data available for impulsive conditions is limited or does not yet exist.

Embodiment Construction

[0023]FIG. 1 illustrates the system 10, which is the assembly of the SuperSpine 100 that connects the helmet 200 to the shoulder pads 300. The assembly is composed of two main components:[0024]1) Spherical Shell Shear Plates (SSSP) with boot (FIG. 2, 101 and FIGS. 3, 101 and 103), and[0025]2) Rotational Shear Anchor (RSA) with quick-release (FIG. 4, 110, and additional details in FIGS. 5, 6 and 7).

[0026]The primary components of the spherical shell shear plates assembly (as shown in FIGS. 3 and 4) are 4 plates (103) with a radius of curvature and positioning on the helmet 200 and shoulder pads 300 such that the center of the sphere would lie in the forward half of the neck just below the jaw. Although the head / neck has many more degrees of freedom available to it that the SSSP, detailed investigations have shown that for the most common head motions, this shape and positioning provides a nearly complete range of motion. The advantage of using spherical shell elements is that it allo...

Abstract

A safety helmet system to minimize brain concussions for athletes experiencing impact loading. A housing incorporates a series of displaceable plates which are displaceable having a shear thickening fluid between the displaceable plates for rigidifying upon impact. The housing is connected on one end to a helmet and to shoulder pads on an opposing end.

Description

FIELD OF USE[0001]This invention is in the field of devices that are designed to prevent concussions of the brain that frequently occur from blows to the head in certain sports such as football, lacrosse, field hockey, etc.BACKGROUND OF THE INVENTION[0002]There are an estimated 1.6 to 3.6 million sport's related concussions occurring annually just in the USA (J A Langlois, W Rutland Brown, M M Wald. (2006) The epidemiology and impact of traumatic brain injury: a brief overview. J Head Trauma Rehabil., 21(5):375-8). In addition to the professional sports, a greater percentage of these injuries occur in children, high school and college athletes who are also susceptible to severe negative effects of sport related concussions with a potentially greater negative impact on long-term quality of life.[0003]The kinematics that induce a concussion are thought to consist primarily of rotational acceleration-deceleration motions of the head. While existing protective helmets are effective at r...
