Abstract: Glasses have a lens arrangement, a glasses frame, and at least one pivot point for joining together the lens arrangement and the glasses frame by pivoting them relative to one another, wherein the glasses frame has a nose support device for support against a nose of a glasses wearer, and wherein the lens arrangement has a nose support device receptacle which, in the joined-together state of the lens arrangement and the glasses frame, receives the nose support device.

Abstract: A goggle lens comprises a main body and at least one transparent, electrically conductive coating that covers the main body at least partly, as well as electrical contact means which cover the at least one coating partly and are in electrical connection with the at least one coating and also form at least one electrical heating zone.

Abstract: A protective helmet including a helmet shell for at least partially covering the head of a helmet wearer, and a holding strap arrangement arranged on the helmet shell for holding the helmet shell on the head of the helmet wearer. The holding strap arrangement includes a chin strap connected to the helmet shell, a first closure part connected to the helmet shell, and a second closure part connected to the chin strap and can be brought into closed connection with the first closure part, with a closure being formed. The closure automatically opens in a first closed position if a predetermined opening tensile force acts between the closure parts, and the closure parts separate from each other. In a second closed position, the first closure part and the second closure part are always in closed connection with each other irrespective of a tensile force acting between the closure parts.

Abstract: A securing system for a helmet has a forehead band having two guiding installations and two neck band portions having in each case one counter guiding installation that corresponds to one of the two guiding installations of the forehead band. Each of the counter-guiding installations for repositioning the respective neck band portion in relation to the forehead band is disposed so as to be displaceable on the corresponding guiding installation.

Abstract: A breathing mask for filtering air exhaled by a wearer of the breathing mask. The breathing mask includes a mask main body for covering the nose and mouth of the wearer, and at least one breathing valve arrangement which is arranged on the mask main body and includes a valve seat body and a valve membrane that is movable between a release position and a closed position, which valve membrane frees a breathing opening in the release position, closes the breathing opening in the closed position, and includes a reinforcement structure with at least one oblique reinforcement body extending obliquely with respect to a central plane of the valve membrane.

Abstract: A pair of spectacles including a lens arrangement having two lateral temple arm bearing arrangements. Each temple arm bearing arrangement has a first hinge lug having a first bearing opening and a second hinge lug having a second bearing opening, and at least one locking member insertion opening configured in the first or second hinge lug. The spectacles additionally comprise two temple arms, which respectively have a temple arm main body, and a bearing pin integrally connected thereto, which bearing pin, in the assembled state, is pivotably connected to the first and second bearing opening of the respective temple arm bearing arrangement. Each temple arm further has at least one locking member, which, in the assembled state, is arranged between the hinge lugs of the respective temple arm bearing arrangement and, in a pivot position, lockingly holds together this temple arm and the lens arrangement.

Abstract: A method for production of an eyeglass temple, the method including an injection of a first material into an injection molding tool upon forming an eyeglass temple main part with a main body and an inclination bearing body, and an injection of a second material into an eyeglass temple adjustment part cavity of the injection molding tool upon overmolding at least partly the inclination bearing body to form an eyeglass temple adjustment part, which is penetrated by the inclination bearing body and pivotable in relation thereto, after the first material has cured at least partly, and a removal of the eyeglass temple, which is in an eyeglass temple injection molding position, from the injection molding tool when the first material and the second material have cured at least partly.
