DETAILED DESCRIPTION OF EMBODIMENTS Attention is first directed to Figs. 1A to 1F of the drawings directed to a first example of a headgear according to the present disclosure, generally designated 20. The headgear 20 is a full-face mask (i.e. namely configured for covering user's eyes. Nose and mouth) useful, by way of example by individuals so as to avoid, or likely reduce risk of engaging pollutants/ infectious organisms.

The headgear 20 comprises a head support generally designated 22 and a facial accessory, namely the face mask 24, and a substantially rigid support arm 26 unilaterally extending between the head support 22 and the facial accessory 24.

The head support 22 is configured with a skull rest 30 having an open curved shape bearing portion, shaped and sized for bearing over posterior head portion 40 of an individual 42 (Fig. 1F), and wherein the skull rest 30 can be padded and/or flexible to an extent, for comfort use.

The facial accessory 24 comprises a transparent visor 32 and a facial rest portion 34 in the form of a cushioning circumferentially disposed over an inside edge portion of the facial accessory 24. The support arm 26 can be substantially rigid though it may be pliable to an extent, and it supports the head support 22 and the facial accessory 24 at a spaced apart relation, where in the illustrated example the head support 22 and the facial accessory 24 are fixed about the support arm 26. The length of the support arm 26 is one- size-fit-all, though it may be manufactured in different lengths so as to conform with different average head sized individuals (e.g. Mini, Small, Medium, Large, Extra Large, etc.) It is noted that the support arm 26 is in fact configured of two longitudinal arms 16A and 26B, though the example of Figs. 1 and 1F illustrates a single armed support arm.

In use (Fig. 1F), the skull rest 30 bears over the posterior head portion 40 whilst the facial rest portion bears over the users face, such that he visor 32 is spaced from the user's face, giving rise to a safe space therebetween, free of potential contamination.

Further, when the headgear 20 is mounted over a user's head, the unilateral support arm 26 is disposed along one side of user's head (right side in the examples), such that the support arm 26 is in close proximity with user's head, and wherein the support arm 26 serves as a mounting/unmounting grip, configurable for applying or removing the headgear using one hand only.

Turning now to Figs. 2A to 2C there is illustrated a headgear according to an embodiment of the present disclosure, generally designated 50, in the form of a half-face mask (namely configured for covering only ones nose and mouth), comprising a head support generally designated 52 and a facial accessory, namely an ergonomically shaped nose-mouth mask 54, and a substantially rigid support arm 56 unilaterally extending between the head support 52 and the facial accessory 54.

The head support 52 is configured with a skull rest 60 having circular (somewhat oval) shape bearing portion 63, shaped and sized for bearing over posterior head portion of an individual (not shown), and wherein the skull rest 60 comprises an anatomically shaped cushioning pad 62 for comfort use, wherein said pad can be replaceable. Further comprised at the skull rest 60 is a mini air propelling unit, namely electric fan 64, configured for propelling ambient air through a filtration unit 66, powered by a power source (namely a battery within encasement 68; rechargeable or not).

The facial accessory 54 comprises a transparent nose-mouth cover 70 and a facial rest portion 72 in the form of a cushioning circumferentially disposed over an inside edge portion of the facial accessory 54. The nose-mouth cover 70 is transparent so that others can read lips of the user and further so that others can identify hazardous conditions of a user, e.g. chocking, vomiting, etc.). The support arm 56 is substantially rigid though pliable to an extent, owing to a rigidifying steel member 74, said support arm 56 supports the head support 52 and the facial accessory 54 at a spaced apart relation, where in the illustrated example the head support 52 and the facial accessory 54 are distantly fixed about the support arm 56, however pivotable over the support arm 56 (i.e. about an axis parallel to a frontal axis of a user). In this example too, the length of the support arm 56 is one-size-fit-all).

The support arm 56 in the present example is a hollow tube being in flow communication between the air propelling unit 64 and an air outlet port 80 at the facial accessory 54, whereby activating the air propelling unit (e.g. by an electric switch, a pressure sensor, position sensor, etc.; not shown) entails pressure built-up at the space 85 between user's face (not shown) and the cover 70. The pressure build-up forces fresh, filtered air to the users respiratory system and yet reduces likelihood of contaminants to enter the space 85. Mounting an using the headgear 50 takes place in the same fashion as discussed in connection with the previous example as disclosed in connection with Figs. 1A to 1F, however with the addition of an active air filtration and propelling system.

The headgear 50 is a detachable configuration, wherein the head support 52 (Fig. 3A) comprises a tubular coupling socket 88 for articulating thereto the tubular support arm 56, such that the coupling socket 88 facilitates air flow therethrough and yet allows for rotational freedom of the support arm 56 with respect to said head support 52. The support arm 56 is detachably attachable to said socket by a clicking coupler 90 (Fig. 3C). such an arrangement is useful for example for cleaning/sterilizing the components, and for fitting a suitable size head support with a support arm, depending on user's anatomy.

Likewise, the facial accessory (nose-mouth mask 54) is detachably attachable to the fore end of the support arm 56, via a locking latch 92 configured for facilitating rotational articulation therebetween.

Figs. 4A and 4B illustrate the headgear 50 (discussed hereinabove wit reference to Figs. 2A to 2C and 3A to 3C) worn/mounted over a user's head 96, wherein the bearing portion 63 of the skull rest 60 bear over the user's posterior head portion 98 and the facial rest portion 72 sealingly bears over the user's face at a spaced apart relation, giving rise to a sealed space 100.

The arrangement disclosed in connection with the example illustrated in Figs. 5A to 5D is principally similar to that disclosed in connection with the example illustrated in Figs. 2A to 2C and 3A to 3C, with reference being made back thereto, and wherein like elements are designated with like reference numbers with an apostrophe mark (').

The headgear generally designated 50', in the form of a half-face mask comprises a head support generally designated 52' and a facial accessory, namely a nose-mouth mask 54' with a substantially rigid support arm 110 unilaterally extending between the head support 52' and the facial accessory 54'. The difference between the present example and the previous example resides primarily in that the support arm 110 comprises two tubular segments 112 and 114 telescopically articulated to one another by a telescopic fluid coupler 116, whereby the effective length of the support arm 110 can be adjusted so as to fit user's anatomy. It is however appreciated that the fluid coupler 116 maintains rigidity of the support arm 110, yet facilitates extension/retraction thereof (in direction of arrow 120 and oppositely) and yet facilitates free air flow therethrough.

Figs. 6A to 6E are directed to yet an example of the present disclosure, illustrating a full-face mask headgear according to the disclosure, generally designated 130. The headgear 130 is similar to the headgear 50 discussed in connection with the example illustrated in Figs. 2A to 2C and 3A to 3C whereby reference is made thereto.

The headgear generally designated 130, in the form of a full-face mask, comprises a head support generally designated 132 and a facial accessory, namely an eyes, nose and mouth nose-mouth mask 134 with a substantially rigid support arm 136 unilaterally extending between the head support 132 and the facial accessory 134, said support arm 136 being rigidified by a steel strip 138 extending along the hollow tube of the support arm.

The head support 132 is configured with a skull rest 140 having circular (somewhat oval) shape bearing portion 142, shaped and sized for bearing over posterior head portion 148 of an individual 150 (Fig. 6E), and wherein the skull rest 140 comprises an anatomically shaped cushioning pad 154. Further comprised at the skull rest 132 is a mini air propelling unit, comprising an electric fan 158, configured for propelling ambient air through a filtration unit 160, powered by a power source (namely a battery within encasement 162).

The facial accessory 134 comprises a transparent eye-nose-mouth cover 164 and a facial rest portion 166 in the form of a cushioning circumferentially disposed over an inside edge portion of the facial accessory 134, for cushioning and gas sealing the face mask over user's face.

In the illustrated example, the head support 132 and the facial accessory 134 are distantly fixed about the support arm 136, however pivotable over the support arm 136 (i.e. about an axis parallel to a frontal axis of a user) and at a detachably attachable fashion, as illustrated in Figs. 6C and 6D, wherein the head support 132 comprises a tubular coupling socket 170 for articulating thereto the tubular support arm 136, such that the coupling socket 170 facilitates air flow therethrough and yet allows for rotational freedom of the support arm 136 with respect to said head support 132. The support arm 136 is detachably attachable to said socket by a (not seen). Likewise, the facial accessory 134 is detachably attachable to the fore end of the support arm 136, via a locking latch 174 configured for facilitating rotational articulation therebetween. such an arrangement is useful for example for cleaning/sterilizing the components, and for fitting a suitable size head support with a support arm, depending on user's anatomy.

Figs. 7A and 7B illustrate a headgear 190 similar to that disclosed in the previous example, the headgear 190 being a full-face mask comprises a head support generally designated 192 and a facial accessory194 with a substantially rigid support arm 196 unilaterally extending between the head support 192 and the facial accessory 196. The difference between the present example and the previous example resides primarily in that the support arm 196 comprises two tubular segments 200 and 202 telescopically articulated to one another by a telescopic fluid coupler 206, whereby the effective length of the support arm 196 can be adjusted so as to sealingly fit over user's head 211 and in compliance with the user's anatomy. It is however appreciated that the fluid coupler 206 maintains rigidity of the support arm 196, yet facilitates extension/retraction thereof (in direction of arrow 210 and oppositely) and yet facilitates free air flow therethrough.

Fig. 8A exemplifies a headgear 220 according to the disclosure, differing from previous examples in that the head support 222 is a non circular curved shape bearing portion 224 and wherein the support arm 228 is configured with two parallelly extending tube members 230A and 230B, with a gripping handle 234 fitted thereon, wherein one of the tubes 230A and 230B serves for propelling filtered (from the filtration system 231) through the air towards the facial accessory, namely the face mask 240, and the other one of the tubes 230A and 230B serves for evacuating gas from the space between the users face and the face mask 240, i.e. exhaled gases.

Figs. 8B to 8G illustrates the headgear 220 of Fig. 8A mounted over a user's head 244, with the bearing portion 224 of the head support 222, shaped and sized for bearing over posterior head portion 250 of the user 244.

The headgear 260 of Figs. 9A and 9B follows the principals as discussed hereinabove, wherein it comprises a head support generally designated 262 and a facial accessory, namely the face mask 264, with a substantially rigid support arm 266 unilaterally extending between the head support 262 and the facial accessory 264.

The head support 22 is configured with a passive filtrating unit 270, i.e. devoid of an air propelling power unit, wherein filtered air flows towards the sealed space 274 between the user's face and the face mask 264 owing to inhaling pressure by the user 278.

Exhaled gases can be exhausted from the space 274 via a one way valve at the face mask (not shown) or towards an outlet valve at the filtrating unit 270 (not shown).
