Abstract
Official abstract text for this publication.
A vehicle window plate has a maximum value of a variation of a curvature in a vertical direction being ±7.6E-6 mm −2 or less at least within a HUD display area. The curvature preferably increases monotonically from a lower side to an upper side at least within the HUD display area.
First claim
Opening claim text (preview).
1 . A vehicle window plate, wherein: a maximum value of a variation of a curvature in a vertical direction is ±7.6E-6 mm −2 or less at least within al-IUD display area. 2 . The vehicle window plate according to claim 1 , wherein: the curvature increases monotonically from a lower side to an upper side at least within the HUD display area. 3 . The vehicle window plate according to claim 1 , wherein: an average value of the variation of the curvature in the vertical direction is ±1.2E-6 mm −2 or less at least within the HUD display area. 4 . The vehicle window plate according to claim 1 , wherein: the variation of the curvature is constant at least within the HUD display area. 5 . The vehicle window plate according to claim 1 , wherein: a position most distant from a chord connecting an upper side and a lower side serving as a reference is located more closely to the upper side than a center position in the vertical direction. 6 . The vehicle window plate according to claim 1 , wherein: a difference in curvatures between a left end portion and a right end portion is 0.00040 mm −1 or less at least within the HUD display area. 7 . The vehicle window plate according to claim 1 , wherein: a maximum value of the curvature is 0.001 mm −1 or less at least within the HUD display area. 8 . The vehicle window plate according to claim 1 , wherein: the HUD display area is 10 cm 2 or more. 9 . The vehicle window plate according to claim 1 , wherein: the vehicle window plate is a glass plate; the glass plate has an area where a plane stress is formed at an outer peripheral edge and inside the outer peripheral edge; and the HUD display area dose not overlap with the area where the plane stress is formed.
