Abstract
Abstract The present invention includes an improved protective football player''s helmet capable of providing improved protection against what is commonly known as ''''spearing'''' and face-guard tackles. The safety helmet or football helmet disclosed by the present invention includes a relatively rigid helmet portion formed with a recess for receiving and protecting the upper and side portions of the user''s head, a chin strap removably secured to the helmet in order to hold same upon the head of the user, and a face-guard assembly which functions both as an additional protective device as well as being cooperative with the chin strap such that, upon preselected and undesirable movement of the face-guard in a forward direction, the chin strap is rendered inoperative and releases the helmet from the user''s head. In an alternate embodiment hereof, the chin strap will not be detached from the face-guard, thereby facilitating refastening.

Claim 1
Independent Claim
196 words
A safety helmet, or the like, comprising cover means formed with a recess for receiving and protecting portions of the head of the user; retaining means for removably holding said cover means on the head, said retaining means comprising a plate assembly having walls that form a slide receiving channel, a substantially unitary slotted face-guard slide bar which includes a first snap fastener affixed thereto, a chin strap having at least one second fastener at extremities thereof, said first and second fasteners being cooperatively capable of engaging one another; an adjustable release force means for controlling a predetermined force necessary to enable a predetermined disengagement of said first and second snap fasteners upon forward movement of said slide bar, said release force means comprising a bolt member cooperatively secured to said plate assembly, and a cap member removably secured to said bolt member; said retaining means enabling said predetermined disengagement of said snap fasteners upon forward movement of said slide bar, said plate assembly further comprising a raised cam surface disposed in the path of said second fastener such that contact therebetween will cause a lifting of said second fastener, thereby resulting in said fastener disengagement.
