A protective shield features a single-piece transparent dome or shell having a rear opening through which facial and cranial regions of a user's head are received, thereby providing improved coverage over conventional face shields that cover the face only. Inward protrusions at a transitional region between the facial and cranial portions of the shield rest against the forehead to offset the facial portion of the shield forwardly of the user's face to allow airflow, optionally introduced from an external fan via an airflow channel integrally formed in the cranial portion. A flexible connector clip has a J-shaped profile for engaging an out-turned flange around the boundary of the shield s rear opening, to enable clipped connection of a bib or shroud. Support protrusions in an underside of the cranial portion maintain airspace above the head, which is further optimized by a rearwardly sloped incline of the cranial portion.
A protective shield comprising a transparent non-spherical dome or shell delimiting a hollow interior space for receiving facial and cranial regions of a user's head therein, said non-spherical dome or shell having a boundary edge thereof that delimits an opening of said hollow interior space through which said facial and cranial regions of said user's head are admitted into said hollow interior space, said opening having an elongated primary dimension measured in one direction thereacross and configured with sufficient length to accommodate a chin-to-crown measurement of the user's head in an inferior-superior anatomical direction, and a shorter secondary dimension measured in a cross-wise direction to said primary dimension and configured with sufficient length to accommodate a narrower width measurement of the user's head in a lateral anatomical direction.

A one-piece adjustable length headband for support of a protective shield on a users head, said headband comprising a singular unitary strip of foam material having al length dimension in which said strip of foam material is elongated relative to width and thickness dimensions thereof that are orthogonal to both one another and to said length dimension, said strip of foam material having opposing first and second ends between which said length dimension is measured, said strip of foam material having a barbed tail region spanning a partial length of the length dimension from the first end toward the second end, and a widened end region that resides adjacent the second end and is of greater measure in the width dimension than said barbed tail region, said strip of foam material being flexibly bendable in said length dimension to bring the first and second ends toward one another to form a closed loop, said barbed tail region being barbed on opposing sides thereof, and said the widened end region having at least one receiver opening therein through which the first end is insertable to engage the barbed tail through said receiver opening, whereupon the barbed sides of the barbed tail region resist pulling of the first end back through said receiver opening, thereby securing the headband in said closed loop, which is adjustable in size by pulling more of the barbed tail onward through said receiver opening.

A two-piece adjustable length headband for support of a protective shield on a users head, said headband comprising a first strip of foam material having a first pair of opposing ends separated from one another by a length dimension of said first strip of foam material, and a second strip of foam material having a second pair of opposing ends separated from one another by a length dimension of said second strip of foam material, one of two widthwise faces of the first strip having a respective piece of hook or loop fastener thereon adjacent each of the first pair of opposing ends, and one of two widthwise faces of the second strip having a respective piece of loop or hook fastener thereon adjacent each of the second pair of opposing ends that is matable with one of the hook or loop fasteners on the first strip, whereby the first and second strips are connectable face-to-face in end-overlapping fashion to form a closed loop, and at least one of the pieces of fastener is elongated in the length dimension of the respective strip of foam material to enable coupling together of the two strips in varying degrees of overlap to thereby adjustably size said headband.
