Abstract
A vehicle window panel assembly and a manufacturing method for such assemblies having a gasket made from a melt-processible material and providing a long-term, failure-resistant bond between the gasket and window panel for retaining the window panel assembly in the vehicle, The gasket material provides a bond which resists both short- and long-term dynamic and static loads exerted on attachment members embedded in the gasket to prevent failure or separation between the gasket member and the window panel assembly for prolonged assembly life and substantial saving to vehicle manufacturers and owners. A method for identifying and selecting the melt-processible material for forming the gasket member is also disclosed.
Claims53
A vehicle window panel assembly, comprising:
- a window panel;
- a gasket attached to at least one surface of said window panel, said gasket formed a melt-processible material selected from the group consisting of thermoplastic urethanes, polyether block amides, or combination thereof, and having a multi-phase morphology;
- and
- at least one attachment member at least partially encapsulated in said gasket and spaced from said window panel for attaching the window panel assembly to the vehicle.
A vehicle window panel assembly, comprising:
- a window panel;
- gasket attached to a surface of said window panel, said gasket formed from a melt-processible material selected from the group consisting of thermoplastic urethanes, polyether block amides, or combinations thereof, and having a multi-phase morphology;
- and
- a plurality of attachment members, each having a first end partially encapsulated in said gasket and spaced from said window panel and a second end extending from said gasket for attaching the window panel assembly to the vehicle.
A vehicle window panel assembly, comprising:
- a window panel;
- a gasket attached to a surface of said window panel, said gasket formed from a melt-processible material having a multi-phase morphology and comprising at least one of thermoplastic urethanes, polyether block amides, or combinations thereof;
- said gasket being at least one of a single-sided encapsulant or a two-sided encapsulant;
- and
- at least one attachment member partially encapsulated in said gasket and spaced from said window panel for attaching the window panel assembly to the vehicle.
