Helmet assemblies with flip-type welding visors
10278867 · 2019-05-07 · ·

Helmet assemblies with flip-type welding visors are provided. A representative helmet assembly includes: a grinding shell having a grinding view port; a welding visor mounted to the grinding shell and having a welding view port; and a connector extending between the grinding shell and the welding visor. The welding visor is rotatable between lower and upper positions. In the lower position, the welding view port is aligned with the grinding view port. In the upper position, the welding visor is rotated toward the back of the grinding shell such that the line of sight of the wearer is unobstructed by the welding view port. Interaction of the grinding shell, the connector and the welding visor, responsive to rotation of the welding visor between the lower and upper positions, provides a biasing force to urge the welding visor towards a selected one of the positions.

Welding Protector With Magnifying Cover

A welding protector (1) has a curved eye protection shield (10) with an electrically switchable light filter. The welding protector further has a magnifying cover (20) for arrangement on an eye facing inner side of the eye protection shield. The magnifying cover is pre-shaped based on a curve that extends equidistant to the curve the eye protection shield is based on. Further, the magnifying cover has two optical lenses (27) which in combination only partially cover the eye protection shield.

Control of Mediated Reality Welding System Based on Lighting Conditions
20190121131 · 2019-04-25 ·

An example head-worn device includes a camera, a display device, weld detection circuitry, and pixel data processing circuitry. The camera generates first pixel data from a field of view of the head-worn device. The display device displays second pixel data to a wearer of the head-worn device based on the first pixel data captured by the camera. The weld detection circuitry determines whether a welding arc is present and generates a control signal indicating a result of the determination. The pixel data processing circuitry processes the first pixel data captured by the camera to generate the second pixel data for display on the display device, where a mode of operation of said pixel data processing circuitry is selected from a plurality of modes based on said control signal.

An eye protection device for a welding mask or the like includes a welding activity detection circuit that is configured to detect welding activity, and a filter driver that controls an optical filter to be in undarkened and darkened states. The filter driver is configured to (i) provide a slower and/or gradual opening of the filter, (ii) insert a user-selected delay and/or gradient between the end of welding activity and the opening of the filter, and/or (iii) cause variation of light transmission values of the filter between a darkened state and an undarkened state based on varying brightness detected by a brightness sensor during transition of the filter from a darkened state to an undarkened state.

An illuminated welding helmet system for selectively illuminating a darkened area during welding operations includes a welding helmet that may be worn during welding and the welding helmet includes an auto lens. A light unit is coupled to the welding helmet and the light unit selectively emits light outwardly from the welding helmet thereby facilitating a darkened area to be visible. The light unit is in electrical communication with the auto lens. Moreover, the light unit is turned on when the auto lens does not detect light and the light unit is turned off when the auto lens detects light.

PROTECTIVE HEADGEAR COMPRISING A CURVED SWITCHABLE SHUTTER AND COMPRISING MULTIPLE ANTIREFLECTIVE LAYERS

Protective headgear with a curved switchable shutter and curved front and rear cover plates and including at least two antireflective layers.

WELDING MASK WITH SENSOR LAMP
