Abstract

Official abstract text for this publication.

A welding helmet ( 1 ) comprising a head suspension unit and a protective shield ( 2 ), the protective shield being pivotally mounted on the head suspension unit between a lowered position in which the protective shield covers a wearer's face, and an upraised position in which the protective shield uncovers the wearer's face, the head suspension unit comprising a head cover ( 100 ) for covering the wearer's head, wherein the head suspension unit includes a removable configurable scrape guard ( 110 ) to protect the wearer's head from impact.

First claim

Opening claim text (preview).

The invention claimed is: 1. A welding helmet comprising a head suspension unit and a protective shield, the protective shield being pivotally mounted on the head suspension unit between a lowered position in which the protective shield covers a wearer's face, and an upraised position in which the protective shield uncovers the wearer's face, the head suspension unit comprising a head cover for covering the wearer's head, wherein the head cover comprises a soft head cover, wherein the head suspension unit includes a removable scrape guard positioned inside the soft head cover to protect the wearer's head from impact. 2. The welding helmet of claim 1 , wherein the scrape guard is removably attached to soft head shield. 3. The welding helmet of claim 2 , wherein the scrape guard is removably attached to soft head cover by hook and loop connection. 4. The welding helmet of claim 1 , wherein the scrape guard has a soft lining on a head-facing surface. 5. The welding helmet of claim 1 , wherein the scrape guard has a circular profile and a series of radially extending protrusions. 6. The welding helmet of claim 5 , wherein the radially extending protrusions bend downwardly in use so as to form a substantially dome-shaped cap. 7. The welding helmet of claim 6 , wherein the scrape guard is configurable by altering the extent of the downward bend of the radially extending protrusions so as to alter the shape of the cap. 8. The welding helmet of claim 1 , wherein the soft head cover comprises an upper head section and a lower neck section, wherein the upper head section conforms broadly to the shape of the head and the lower neck section extends downwardly and rearwardly from a neck area of a user to provide air space between the neck area of the user and the head cover. 9. The welding helmet of claim 1 , wherein the scrape guard comprises a plastic material that is elastically deformable to allow for conformity with the head of the wearer. 10. The welding helmet of claim 9 , wherein the plastic comprises a bendable material having a hardness sufficient to protect the head of the user from impact against hard surfaces and sharp objects.
