Claims23
A laminated windshield of a vehicle, the laminated windshield being resistant to projections of gravel and comprising:
- at least one outer glass sheet for facing an exterior of the vehicle,
- at least one inner glass sheet for facing an interior of the vehicle, the inner glass sheet having a thickness of not more than 1.1 mm, and
- a polymeric sheet located between the inner and outer glass sheets,
- wherein the inner glass sheet is thinner than the outer glass sheet,
- wherein the outer glass sheet has a thickness of not more than 1.6 mm and a coefficient of thermal expansion of less than 50×10−7 K−1,
- wherein the inner glass sheet has a chemical composition of a soda-lime glass, and
- wherein the laminated windshield is a bent windshield for being mounted to the vehicle such that the inner glass sheet is more proximal to the interior of the vehicle than the outer glass sheet is, and
- wherein the polymeric sheet has a thickness from 500 μm to 4 mm.
The laminated windshield as claimed 1, wherein the outer glass sheet has a thickness of not more than 1.1 mm.
A bent laminated windshield of a vehicle, the bent laminated windshield being resistant to projections of gravel and comprising:
- at least one bent outer glass sheet with a convex outer surface for facing an exterior of the vehicle,
- at least one bent inner glass sheet with a concave inner surface for facing an interior of the vehicle, the bent inner glass sheet having a thickness of not more than 1.1 mm, and
- a polymeric sheet located between the inner and outer glass sheets,
- wherein the bent inner glass sheet is thinner than the bent outer glass sheet,
- wherein the bent outer glass sheet has a thickness of not more than 1.6 mm and a coefficient of thermal expansion of less than 50×10−7 K−1,
- wherein the bent inner glass sheet has a chemical composition of a soda-lime glass,
- wherein the bent laminated windshield is for being mounted to the vehicle such that the bent inner glass sheet is more proximal to the interior of the vehicle than the bent outer glass sheet is, and
- wherein the polymeric sheet has a thickness from 500 μm to 4 mm.
A vehicle comprising a bent laminated windshield, the bent laminated windshield being resistant to projections of gravel and comprising:
- at least one outer glass sheet for facing an exterior of the vehicle,
- at least one inner glass sheet for facing an interior of the vehicle, the inner glass sheet having a thickness of not more than 1.1 mm, and
- a polymeric sheet located between the inner and outer glass sheets,
- wherein the inner glass sheet is thinner than the outer glass sheet,
- wherein the outer glass sheet has a thickness of not more than 1.6 mm and a coefficient of thermal expansion of less than 50×10−7 K−1,
- wherein the inner glass sheet has a chemical composition of a soda-lime glass,
- wherein the bent laminated windshield is mounted to the vehicle such that the inner glass sheet is more proximal to the interior of the vehicle than the outer glass sheet is, and
- wherein the polymeric sheet has a thickness from 500 μm to 4 mm.
