Abstract

A welding-type helmet includes a cover with a channel recessed from an external surface of the cover, the channel being configured to house a removable light source within the channel.

First claim

What is claimed is:

1. A welding-type helmet comprising:
a lens defining a top, a bottom, a first side, and a second side, wherein the lens is coupled to the helmet and configured to protect a user wearing the helmet; and
a channel recessed from an external surface of the helmet and adjacent to at least one of the top, bottom, first side, or second side of the lens, the channel being externally accessible from the helmet and configured to receive and house a removable light source that is surrounded on three sides by the channel,
wherein a space is formed within the channel between: 1) a surface of the light source, and 2) a plane corresponding to the external surface of the helmet, when the light source is housed within the channel.

2. The helmet as defined in claim 1 , further comprising a protective cover configured to fit within the space such that an exterior surface of the protective cover is substantially flush with the external surface of the helmet, wherein the protective cover comprises a translucent silicon material or a translucent polymer material.

3. A bezel for an industrial helmet comprising:
a channel with two internal side walls and an internal surface configured to house a removable light source in contact with the internal surface of the channel within the channel; and
a protective cover configured to fit within a space within the channel such that an exterior surface of the protective cover is flush with an outermost surface of the two internal side walls, wherein an external surface of the bezel slopes upward to the outermost surface of each internal side wall at an angle with respect to the external surface of the bezel.

4. The bezel as defined in claim 3 , wherein the two internal side walls extend from the external surface of the bezel such that the internal surface of the channel is coplanar with the external surface of the bezel.

5. The bezel as defined in claim 4 , wherein, when the light source is housed in the channel, the two internal side walls extending beyond the light source to create the space within the channel.

6. The bezel as defined in claim 3 , wherein the bezel is configured to removably attach to a welding-type helmet, the light source being configured to connect with a power source remotely located from the helmet.

7. The bezel as defined in claim 3 , further comprising a battery to power the light source, the battery secured to the helmet as a removable battery pack by a frame configured to secure a clip and the battery pack at a rear portion of the frame.

8. A welding-type helmet comprising:
a bezel configured to removably attach to the helmet, the bezel including a channel recessed from an external surface of the bezel, wherein a space is formed within the channel between: 1) a surface of a light source, and 2) a plane corresponding to the external surface of the bezel when the light source is housed within the channel; and
a protective cover comprising a translucent material configured to fit within the space such that an exterior surface of the protective cover is substantially flush with the external surface of the bezel.

9. The bezel as defined in claim 3 , wherein the bezel is configured to removably attach to a surface of a welding-type helmet, the bezel arranged between the welding-type helmet and the light source.
