Abstract
Abstract A motor vehicle window assembly comprises a windshield, a window frame flange in parallel spaced relationship to a marginal area on the rear surface of the windshield and a looped trim strip. The looped trim strip includes a channel portion embracing the edge of the windshield and a dam portion spaced apart from and connected with a rear channel wall lying against the rear surface of the windshield by a plurality of bridges. The rear channel wall, dam portion and the rear surface of the windshield forms a channel into which an adhesive is injected. The adhesive bonds the windshield to the flange of the window frame and is prevented from being exposed to the ambient atmosphere by means of the rear channel wall and dam portion which lie against the flange.
