<p>A unique dynamic seal assembly for use in a mold structure for encapsulating a glass window assembly (30) with a gasket (46). A seal assembly resiliently supports the window assembly (30) and coorperates with mold structure (31) for defining a gasket forming cavity. The mold structure (31) includes two cooperating mold sections (32), (33), each of which can be provided with a groove (37), (42) for receiving a separate dynamic seal assembly. Each seal assembly includes a sealing body (36), (41) having a sealing surface (36a), (41a) which faces and sealingly contacts window assembly (30) and preferably at least one outwardly extending fin (77) formed thereon in contact with a wall of groove (37), (42). The seal assembly also includes a fluid filled bladder (39), (43) positioned between sealing body (36), (41) and cooperating mold section (32), (33). When increased pressure is applied to a local area of the seal as a result of a contour difference between the seal and window assembly (30), bladder (39), (43) deforms to automatically transfer at least a portion of the applied pressure to adjacent areas of the seal. Such a seal construction produces a more effective seal, produces a true gasket contour, and reduces seal fatigue, thereby increasing the life of the seal.</p> |
