A method for producing an automotive glazing with an optical sensor device, with the glazing having superior optical qualities, including the steps of applying an enamel obscuration mask on at least one face of at least one glass sheet, where the obscuration mask extends to an area where the at least one optical sensor device will be fixed and includes at least one opening on the automotive interior side so as to be capable of acquiring information through the opening from the optical sensor device intended to be fixed at the at least one opening; drying or firing the enamel obscuration mask; applying a washable cover layer resisting at a temperature of at least 620° C. on the surface of the at least one opening; submitting the glass sheet to a heat treatment above 450° C. during a bending or tempering process; and removing by washing the washable cover layer.

Automotive glazing having superior optical quality

The invention concerns a glazing panel comprising first () and second () glass sheets linked together via at least one spacer () which holds them a certain distance apart from one another and, between said glass sheets (), an inner space () comprising at least one first cavity (), in which there is a vacuum of less than 100 mbar and which is closed by a peripheral seal disposed at the periphery of the glass sheets, around said inner space (), the seal () being a metal seal rigidly connected respectively to the first and second glass sheets. According to the invention, the metal seal () further comprises at least one hollow metal tube () of which a first end () communicates with the inner space () and a second end () communicates with the outside of the panel, the second end () comprising means for blocking the tube. According to the invention, the tube comprises at least one gas trap () rigidly connected to the inside of the tube ().

Glazing panel comprising glass sheets linked together via spacers and corresponding production method

The invention relates to a glass panel including a first () and a second () glass sheet combined together via at least one spacer () that keeps the glass sheets at a certain distance from each other, wherein an inner gap () between said glass sheets () includes at least a first recess () in which a vacuum of lower than 1 mbar is formed, said recess being sealed by a peripheral seal arranged at the periphery of the glass sheets around said inner space (), the seal () being a metal seal rigidly connected to the first and second glass sheets, respectively. According to the invention, the metal seal () further includes a means () for placing the inner gap () in communication with the outside of the panel, wherein said communication means can be sealed.

Glazing panel including glass sheets joined together by means of spacers and corresponding method for manufacturing same

The invention relates to a glazing panel (), particularly an insulated glazing panel, comprising at least a first () and a second () sheet of glass which are joined together by an intercalated surround () which holds them a certain distance apart, and between said at least two sheets of glass at least one internal space () closed by the intercalated surround positioned around said internal space. According to the invention, the intercalated surround () comprises an opening () causing the internal space () to communicate with the outside of the panel, the panel comprises at least one electrically conducting element () inserted into the opening, a first end () of the conducting element being situated inside the internal space and a second end () of the conducting element being situated outside the internal space, and the panel also comprises a first plug () of thermoplastic elastomer material closing the opening () around the electric conducting element.
