Abstract:
(EN) In order to prevent a reduction in the accuracy of information acquired by an information acquisition device, a windshield according to the present invention comprises a glass sheet, such as a laminated glass sheet 5, having on the vehicle interior surface thereof an antifogging film 8 containing a water repellent group and a metal-oxide composition. The surface of the glass sheet has an information acquisition region 12 which is disposed facing the information acquisition device 2 so as to allow light 22 travelling to the information acquisition device to pass therethrough. The antifogging film 8 is formed so as to cover at least the information acquisition region 12. The information acquisition region 12 may be isolated by a separation region 71, on which a blocking film 7 is formed, from a transparent region 11 providing the driver with a view of the outside. The antifogging film 8 may be formed so as not to cover the transparent region 11.
(FR) Afin d'empêcher une réduction de la précision d'informations acquises par un dispositif d'acquisition d'informations, un pare-brise selon la présente invention comprend une plaque de verre, telle qu'une plaque de verre stratifié (5), dont la surface intérieure du véhicule présente un film antibuée (8) contenant un groupe hydrofuge et une composition d'oxyde métallique. La surface de la plaque de verre comprend une région d'acquisition d'informations (12) qui est disposée en face du dispositif d'acquisition d'informations (2) de manière à permettre à la lumière (22) se déplaçant vers le dispositif d'acquisition d'informations de passer à travers cette dernière. Le film antibuée (8) est formé de manière à recouvrir au moins la région d'acquisition d'informations (12). La région d'acquisition d'informations (12) peut être isolée par une région de séparation (71), sur laquelle un film de blocage (7) est formé, d'une région transparente (11) fournissant au conducteur une vue de l'extérieur. Le film antibuée (8) peut être formé de manière à ne pas recouvrir la région transparente (11).
(JA) 情報取得装置により取得される情報の精度の低下を防止するために、本発明によるウインドシールドは、例えば合わせガラス5であるガラス板の車内側の表面に、撥水基及び金属酸化物成分を含む防曇膜8を備えている。ガラス板の表面は、情報取得装置2に入射する光22が透過し、情報取得装置が対向して配置される情報取得領域12を有する。防曇膜8は、少なくとも情報取得領域12を覆うように形成されている。情報取得領域12は、遮蔽膜7が形成された分離領域71により、運転者が車外を視認するための透視領域11と分離されていてもよい。防曇膜8は、透視領域11を覆わないように形成されていてもよい。
