摘要:
L'invention concerne un pare-brise feuilleté chauffant constitué de deux feuilles de verre réunies par une feuille intercalaire thermoplastique, comprenant d'une part un système de couches conducteur couvrant l'essentiel de la surface d'une feuille de verre du pare-brise alimenté électriquement par des busbars, et d'autre part un réseau de fils chauffants en contact avec le système de couches, électriquement non isolé de celui-ci, réseau situé dans la zone de repos des essuie- glace, les deux moyens de chauffage, système de couches et réseau de fils,étant situés du même côté de la feuille intercalaire, des lignes rompant la continuité électrique localement du système de couches conducteur étant pratiquées à l'emplacement correspondant à la zone de repos des essuie-glaces, ces lignes et le réseau de fils chauffant étant disposés respectivement de telle sorte que le courant alimentant les fils chauffant passe sur toute la longueur de ceux-ci, en isolant électriquement les fils chauffants des busbars, et des boucles des fils entre elles.
摘要:
A laminated glazing comprising two panes of glazing material, a sheet of interlayer material extending therebetween, and an electrically conductive member formed (possibly etched) from a sheet of electrically conductive material also positioned between the panes. The electrically conductive member may be a heating element which comprises a plurality of spaced apart, fine heating lines, electrically connected to a pair of busbars. The heating element may be divided into at least two heating zones, each having a different power density, and/or it may include a non-heated area. Also a method of manufacturing such a glazing involving locating a pre-formed electrically conductive member and . a sheet of interlayer material on a first pane of glazing material, placing a second pane of glazing material in register with the first so that the electrically conductive member and the interlayer material are between the two panes, and laminating in an autoclave.
摘要:
Functional layers do not have a good performance at lower temperatures. This limitation is overcoming by combining the functional layers with a resistive heating circuit. The heating circuit uses minimal power to maintain the glazing at or above the temperature required for acceptable operation.
摘要:
A windshield wiper park position heater employs an area-type heater construction having a flexible substrate supporting a high resistance heater material between electrodes of a lower resistance electrode material. The high length-to-width of the heater element is accommodated through a bus structure that orients current flow along the shortest dimension of the heater and by supplying power at a midpoint of the bus structure to decrease voltage drop over the longest dimension of the heater. A clip structure allows internal conductive layers of laminated connection point between heater components to be simply joined in the crimping operation.

Die vorliegende Erfindung betrifft eine beheizbare laminierte Seitenscheibe für ein offenbares Seitenfenster eines Fahrzeugs, mit einer Oberkante (O), einer Unterkante (U), einer Vorderkante (V) und einer Hinterkante (H), mindestens umfassend eine Außenscheibe (1) und eine Innenscheibe (2), welche über eine thermoplastische Zwischenschicht (3) miteinander verbunden sind, und mindestens einen in die Zwischenschicht (3) eingebetteten Heizdraht (4), welcher zwischen einer ersten Stromsammeischiene (5) und einer zweiten Stromsammeischiene (6) verläuft und mit den Stromsammeischienen (5, 6) elektrisch leitend verbunden ist, wobei die erste Stromsammeischiene (5) und die zweite Stromsammeischiene (6) entlang der Vorderkante (V) oder der Hinterkante (H) angeordnet sind.
摘要:
The disclosure is directed to a transparent armor laminate having a glass, glass ceramic or ceramic strike face layer, one or a plurality of glass, glass ceramic ("GC"), ceramic ("C") or polymeric ("P") backing layer behind the strike face layer, one or a plurality of spall catcher ("SC") layers behind the backing layer(s), and a thin cover glass layer laminated to the strike face, the thin layer being the first layer to be impacted by any incoming projectile or debris. The cover glass has a thickness =3mm. In another embodiment the cover glass thickness is =1mm. Additionally, a defrosting/defogging element is laminated between the cover glass and the strike face.
摘要:
A heatable glazing is disclosed in which electrical heating elements such as fine wires are connected to a bus bar. The resistance of the bus bar is chosen such that, at the supply voltage of the installation, the bus bar provides heating of a portion of the glazing in which it is located.
摘要:
A laminated glazing (e.g. a vehicle windscreen) comprising two panes of glazing material (e.g. glass) having a ply of laminating interlayer extending between them, and one or more wires between the panes of glazing material, each having a conductive central core and an outer dark-coloured (e.g. black) sheath, which is substantially resistant to colour- and substance-degradation by ultraviolet light. The wires may be in the form of a capacitive sensing plate, an inductive coupling loop, a heating element, an antenna and/or an RFID tag.
