Protective athletic garment

Abstract

A protective athletic garment provides segmented padding is patterned to conform to the size, shape and motion of the muscles it is protecting. Segmented padding is supplemented in joint areas by tangentially-stepped articulated shielding, each comprising a hingeably interconnected series of rigid shells. The structure and orientation of the shells deflects impact forces tangentially, while the rotational mobility of the shielding has a force-damping effect.

Description

BACKGROUND OF THE INVENTION[0001]The present invention relates to the field of protective garments, and more particularly to garments to protect athletes competing in contact sports, such as lacrosse, football, hockey and motocross. While the present invention is primarily directed to protective athletic garments, however, it is also applicable to garments used in any activity involving potential high-impact bodily contact where there is a need provide protection without unduly restricting mobility.[0002]Protective garments and equipment designed for use in contact sports typically rely on two modes of dissipating impact forces: padding and shielding. Padding dissipates the force through elastic deformation of the padding material, while shielding deflects a portion of the force away from the body. Optimally, padding and shielding are used in combination, with padding underlying shielding, so that undeflected forces transmitted through the shield can be absorbed by the padding benea...

Benefits of technology

[0013]Segmentation of the padding is patterned to conform to the size, shape and motion of the muscles it is protecting. Using the front of an upper body garment as an example, interior padding over the chest could comprise two large triangular foam segments over the right and left pectorals separated by an exterior vertical oblong strip of raised square or rectangular gel segments over the sternum. The outer sides of the upper arms and forearms could be covered with exterior padding comprising clusters of cubical or hemispherical cells containing compressed air, for greater mobility. Over the clavicle, exterior padding might consists of narrow raised polymer strips running across the shoulder, so as not to impede the upward movement of the arm.

[0015]The tangentially-stepped articulated shielding of the present invention will dissipate impact forces in two ways. First, an oblique impact to one of the shells will tend to move it in the direction of least resistance, which is at a tangent to the underlying body contour, so that the orthogonal component of the force is re-directed and deflected. Second, an orthogonal or oblique impact to one of the shells will generate a torque causing the shell to rotate about the hinge connecting it to the adjacent shell. This rotational motion will be transmitted down the series of interconnected shells, thereby generating an undulating movement which tends to dampen the force. Since this undulating motion of the shielding has both horizontal and vertical components, the orthogonal force component is again reduced. Moreover, the undulating transmission extends the force over a larger body area and protracts the time interval during which the force is applied to the body, thereby reducing the resulting pressure on the body.

Problems solved by technology

The major problem in designing effective athletic gear is the need to balance protection versus mobility.

Shoulder protectors suitable for a football lineman, for example, would be much too confining for a quarterback or wide receiver, while a quarterback's lighter padding would be ineffective for blocking on the line.

But, since segmentation and articulation introduce additional degrees of freedom of movement to padding and shielding beyond that associated with their protective functions, it's important that the mobility dynamics of the padding and shielding not work at cross purposes to their protective dynamics.

But, while facilitating elbow movement, such segmentation would also leave the most sensitive outer part of the elbow exposed every time the elbow was bent.

But the same padding beneath a two-piece panel may be subject to sideward pressure which limits its downward compression and reduces force dissipation.

While pocket-type padding has the advantage of versatility, the padding adds to the bulk of the garment and impedes mobility.
