Abstract
A window assembly and method of forming a window assembly that is constructed to maintain separation of the environments separated by the window assembly when the window assembly is subjected to impacts and cooperate with the structure of associated with defining the window opening without detracting the operability of the window assembly relative to openings defined by the structure of third party original equipment manufacturers structures.
Claims20
A window assembly comprising:
- a first glass layer and a second glass layer that define opposing lateral sides of a window assembly and which each have a corresponding curved shape;
- a first adhesive layer and a second adhesive layer that are each comprised of one of an ethylene vinyl acetate (EVA) adhesive or a polyvinyl butyral (PVB) adhesive and such that the first adhesive layer overlies and extends radially beyond at least one side of the first glass layer and the second adhesive layer overlies at least one side of second glass layer;
- a reinforcement layer comprising one of a polyethylene terephthalate (PET) or thermoplastic polyester polyethylene terephthalate glycol (PET-G) layer that overlies and is disposed between the first adhesive layer and the second adhesive layer, the reinforcement layer having a lateral thickness between 3 mm and 45 mm and wherein the first adhesive layer, second adhesive layer, and reinforcement layer are trimmable to correspond to the curved shape of the first glass layer and the second glass layer;
- and
- wherein the window assembly remains intact when subjected to at least a 5 pound ball drop test from 30 feet and has a thickness that allows the window assembly to be secured to an opening defined by an original equipment manufacturer (OEM) mounting arrangement.

The window assembly of 1 further comprising another reinforcement layer and another adhesive layer disposed between the reinforcement layer an adjacent one of the first adhesive layer and the second adhesive layer.
A window assembly comprising:
- a first glass layer disposed on a first side of the window assembly;
- a second glass layer disposed on a second side of the window assembly, each of the first glass layer and the second glass layer having a curved shaped;
- a first adhesive layer and a second adhesive layer that are each comprised of one of an ethylene vinyl acetate (EVA) adhesive or a polyvinyl butyral (PVB) adhesive and such that the first adhesive layer overlies and extends radially beyond an inward facing side of the first glass layer and the second adhesive layer overlies and extends radially beyond an inward facing side of the second glass layer;
- and
- a reinforcement layer comprising one of a polyethylene terephthalate (PET) or thermoplastic polyester polyethylene terephthalate glycol (PET-G) layer having a thickness between 3 mm and 45 mm that overlies and is disposed between the first adhesive layer and the second adhesive layer and such that the first adhesive layer, the second adhesive layer, and the reinforcement layer are trimmable after securing between the first glass layer and the second glass layer to correspond to a shape of the first glass layer and the second glass layer such that the window assembly remains intact when the window assembly is subjected to at least a 5 pound ball drop test from 30 feet.
2 more elements
A method of forming a window assembly;
- the method comprising:
- acquiring a first pane of glass that is one of a tempered, annealed, or heat strengthened pane of glass;
- acquiring a second pane of glass having the same shape as the first pane of glass and that is one of a tempered, annealed, or heat strengthened pane of glass, each of the first pane of glass and the second pane of glass having a curved shape;
- adhering a first adhesive layer formed of one of an ethylene vinyl acetate (EVA) adhesive or a polyvinyl butyral (PVB) adhesive to a respective side of the first pane of glass such that the first adhesive layer extends radially beyond the first pane of glass;
- adhering a reinforcement layer formed of one of a polyethylene terephthalate (PET) layer or thermoplastic polyester polyethylene terephthalate glycol (PET-G) layer having a thickness between 3 mm and 45 mm to the first adhesive layer so that the reinforcement layer overlies the first adhesive layer;
- and
- adhering a second adhesive layer formed of one of the ethylene vinyl acetate (EVA) adhesive or the polyvinyl butyral (PVB) adhesive to an exposed surface of the reinforcement layer so that the second adhesive layer overlies the reinforcement layer and an exposed surface of the second adhesive layer can receive the second pane of glass and trimming the first adhesive layer, the reinforcement layer, and the second adhesive layer to correspond to a shape of the first pane of glass and the second pane of glass and such that, when assembled, the window assembly remains intact when subjected to at least a 5 pound ball drop test from 30 feet.
