Protective helmet with attachment ring

Abstract

A protective helmet adapted to receive and protect the head of a wearer includes an outer shell and an attachment ring removably secured to the outer shell, such that the attachment ring can be selectively attached to or detached and removed from the outer shell. The outer shell is shaped to protect the head of the wearer of the protective helmet and defines a bottom opening and an internal cavity for receiving the head of the wearer. The attachment ring acts as a point of attachment for, and thus secures, one or more components of the protective helmet configured to engage the head of the wearer, such that the components secured to the attachment ring are transported with the attachment ring when the attachment ring is detached and removed from the outer shell.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]The present application claims priority to U.S. Patent Application Ser. No. 62 / 882,728 filed on Aug. 5, 2019, the entire disclosure of which is incorporated herein by reference.BACKGROUND OF THE INVENTION[0002]The present invention relates to a protective helmet. Protective helmets are commonly worn in the workplace to prevent or reduce the likelihood of head injuries. For example, a hard hat is the most common and well-recognized protective helmet. For another example, a fire helmet is another common protective helmet. Such protective helmets, including hard hats and fire helmets, commonly are comprised of three primary components—an outer shell, a headband, and a suspension—which cooperate to reduce the potential for injury by attenuating some translational energy of the force of an impact to the helmet. Certain protective helmets, including fire helmets, sometimes also include an inner shell (or liner) positioned between the outer shel...

AI Technical Summary

Benefits of technology

[0010]In some embodiments, the protective helmet further includes an inner liner positioned within the internal cavity defined by the outer shell to further attenuate the translational energy of the force of an impact. In some embodiments, the inner liner is supported by a shelf defined by the attachment ring, such that the inner liner can be removed from the internal cavity defined by the outer shell by detaching and removing the attachment ring from the outer shell. In some embodiments, the attachment ring includes inner wall portions that extend upwardly from the shelf to sandwich the inner liner between the attachment ring and the outer shell, thereby maintaining the position of the inner liner when the protective helmet is assembled.

[0011]For increased comfort, in some embodiments, the protective helmet includes ...

Problems solved by technology

By securing each component of the protective configured to engage the head of the wearer to the attachment ring instead of directly to the outer shell in such embodiments, the outer shell can be constructed free ...
