Abstract: An electrochromic dimming system is proposed having two flat electrodes disposed on respectively a first and a second carrier, and an electrochromic layer arrangement, of which at least one element is arranged between the electrodes. The electrodes are provided with contact elements via which the electrodes can be connected to a voltage/current source. In the region of the peripheral edge of the electrode of the first carrier is arranged an annular conductive element which, possibly with the interposition of a conductive layer, is pressed onto the region of the peripheral edge of the second carrier receiving the other electrode. In the region of the peripheral edge of the second carrier is provided at least one feedthrough for connecting the one electrode to the current/voltage source.

Abstract: The invention relates to an eclectrochromic glass component, particularly for motor vehicle mirrors, which contains a doped ion-conducting basic polymer (4) as the ion-conducting layer. The electrochromic glass component consists, for example of a glass substrate (1) as well as a layer system having an electrochromic layer (2), a mirror layer (3), a doped polymer membrane (4), for example of polybenzimidazole polymer, a proton store (5), a rear electrode (6) and a polyester film (7). The layer system is sealed by a seal (8) which closes the coating system towards the glass substrate (1).
