Description

TECHNICAL FIELD

This invention relates to the field of protective headgear. More specifically, the invention pertains to adjustable headgear.

BACKGROUND

Protective headgear worn by athletes and sport enthusiasts typically includes some form of padding to prevent injury to the athlete's head. Such injuries can result from a magnitude of athletic activities including football, flag football, 7 on 7 football, rugby, soccer, field hockey, lacrosse, basketball, cycling, or in-line skating etc.

The existing forms of padding are relatively inflexible and are not shaped to bend to the contour of the athlete's head. Further, current protective headgear does not allow for precise adjustment. The athletes are currently unable to adjust their protective headgear to uniquely fit their particular head shape.

There exists a need in the art for protective headgear that allows the athlete to adjust the protective headgear to fit their unique head shape to provide the best fit possible providing maximum protection during athletic events.

SUMMARY

In an embodiment, an example protective headgear may comprise a front section comprising padding configured to conform to a shape of a head of a wearer, a back section attached to the front section. The back section may comprise one or more adjustment members adjacent an opening in the back section. The protective headgear may comprise one or more pads configured to removeably attach to the adjustment member to define a horizontal adjustment and a vertical adjustment of the back section and at least partially cover the opening in the back section.

In another embodiment, an example apparatus may comprise a three-point adjustment system comprising three hook and loop closure points disposed in a back opening of a protective headgear and allowing for horizontal adjustment and vertical adjustment of a size the protective headgear. The protective headgear may comprise a padded section configured to conform to a shape of a head of a wearer.

In another embodiment, an example adjustment system for protective headgear may comprise a first adjustment member defining a first portion of a back opening of a protective headgear, a second adjustment member defining a second portion of the back opening, a third adjustment member defining a third portion of the back opening, and a flap configured to removeably cover at least a portion of the back opening. The first adjustment member, the second adjustment member, and the third adjustment member may be configured to removeably attach to the flap when at least partially covering the back opening, thereby adjusting a size of the protective headgear and causing padding of the protective headgear to conform to a head of a wearer.

In yet another embodiment, the protective headgear of the present disclosure utilizes closed cell compression molded foam combined with mesh and hook and loop closures and elastic strap that allow the protective headgear to have a more custom fit than other protective headgear on the market. The three-point adjustment system allows the athlete to fit the size and shape of the headgear both horizontally and vertically to their particular head.

DETAILED DESCRIPTION OF ILLUSTRATIVE EMBODIMENTS

In an aspect, the present disclosure relates to an apparatus and an adjustment system thereof. The apparatus may comprise protective headgear. The protective headgear may be designed for a user engaged in a dangerous activity, such as sports. The apparatus may comprise padding to protect the wearer from injury. The padding may be comprised of medium density closed cell outer foam, a semi-rigid moldable composite core, and low-density interior foam. The mix of these particular materials allows for the reduction of the force that is incurred by potential hits to the athletes head.

The apparatus may comprise a flexible material attached to the padding. The flexible material may allow the apparatus to adapt to the shape of the wearer's head. The flexible material may be breathable allowing for ventilation of the wearer. It should be understood that the relationship between the flexible material and padding is such that various patterns can be deployed to achieve the objectives of the disclosure.

The apparatus may comprise an adjustment system. The adjustment system may comprise hook and loop closure points or other fasteners (e.g., any set/release mechanism) that can be adjusted horizontally and vertically to secure the headgear to the size and shape of the wearer's head. The adjustment system may comprise a multi-point adjustment system that allows for one or more pads to be pulled up and attached to the fasteners. The adjustment system may comprise an inner pad that attaches to an interior of the apparatus and an outer pad that attaches to an exterior of the apparatus.

In the inside of the apparatus, interior padding may be used that comprises compression molded padding creating air flow channels which keep the wearer cool. An elastic strap on a lower portion of the back of the apparatus allows the athlete to take the helmet on and off without having to adjust the fit. Once the apparatus is on the wearer, the apparatus also assists in providing a secure fit by sitting underneath the occipital bone.

FIG. 1 is a front perspective view of an example apparatus 100 in accordance with the present disclosure. The apparatus 100 may comprise headgear, such as protective headgear. For example, the apparatus 100 may protect a wearer during a competitive event.
