Benefits of technology

The patent describes a device to protect a person's head and neck from injury during an impact. The device includes a helmet and a brace, along with two units that redirect force in response to impact. One unit helps resist compressive strain, while the other unit helps resist tensile strain. The device uses a combination of telescopic struts, viscoelastic hoods, and cables and compressive members. The technical effect of this invention is to provide better protection against head and neck injuries during impacts.

Problems solved by technology

Head injuries arise from damaging forces applied directly to the head or to the body that result in a rapid acceleration of the head.
TBI has been identified as a major public health concern by the U.S. Center for Disease Control and Prevention, and is a leading cause of death and disability worldwide.

Embodiment Construction

[0039]The following examples and embodiments serve to illustrate the present disclosure. These examples are in no way intended to limit the scope of the disclosure.

[0040]To reduce the incidence of fatalities and severe TBI, helmets are designed with the goal of reducing the amplitude and duration of translational acceleration. Two basic principles are employed in helmets. First, a rigid outer shell spreads a contact force over a larger area on the helmet and the head thereby reducing stress on the skull. Second, an inner padding material deforms during collision, which lengthens the time of the impulse while reducing the maximum force.

[0041]Focal brain trauma is largely a solved issue today as helmets can effectively distribute concentrated forces. However, because mTBI and severe TBI have different physical injury mechanisms, modern shell helmets are not sufficient to address both forms of TBI. While reported cases of severe TBI have been dramatically reduced, diffuse inertial inju...

Abstract

Described herein is a wearable device for redirecting head impact force from the head of a person to other body part or parts of the person, the device comprising: a helmet wearable on the head of the person; a brace wearable on the body of the person; and at least one force redirecting unit configured for connection to the helmet and the brace, wherein at least one of the force redirecting unit is configured to be compressed to carry compressive load, and at least one of the force redirecting unit is configured to be extended to carry tensile load.

Description

CROSS REFERENCE TO RELATED APPLICATION[0001]This application claims the benefit of U.S. Provisional Application Ser. No. 61 / 914,574 filed on Dec. 11, 2013, the disclosure of which is incorporated herein by reference in its entirety.FIELD OF THE DISCLOSURE[0002]The present disclosure, in general, relates to a device for redirecting the head impact force to reduce the risk of head injury.BACKGROUND[0003]The following discussion of the background of the disclosure is merely provided to aid the reader in understanding the disclosure and is not admitted to describe or constitute prior art to the present disclosure.[0004]Head injuries arise from damaging forces applied directly to the head or to the body that result in a rapid acceleration of the head. The resulting translation and rotation of the head have both been linked to neurological outcomes associated with brain injury. Brain injury may occur due to either (1) focal trauma from concentrated forces causing a rapid, focal translatio...
