Abstract

A glass carrier plate that includes a front side, a back side and a circumferential edge zone. A mirror plate with a mirror plate front side, a mirror plate back side and a circumferential edge, wherein the mirror plate back side is attached by means of an adhesive layer on the front side of the glass carrier plate. Holding bars extend from the circumferential edge zone of the front side of the glass carrier plate. The holding bars are distributed over the circumferential edge zone and the circumferential edge of the mirror plate engages the holding bars so that the mirror plate is spaced from and positioned over the front side of the glass carrier plate.

Claims

1. A glass unit for a vehicle mirror assembly, said glass unit comprising:

a glass carrier plate that includes a front side, a back side and a circumferential edge zone;

a mirror plate with a mirror plate front side, a mirror plate back side and a circumferential edge, wherein said mirror plate back side is attached by means of an adhesive layer on said front side of said glass carrier plate; and

,

holding bars extending from said circumferential edge zone of said front side of said glass carrier plate, said holding bars being distributed over said circumferential edge zone, and said circumferential edge of said mirror plate engaging said holding bars so that said mirror plate is spaced from and positioned over said front side of said glass carrier plate.

2. The glass unit of claim 1 wherein said holding bars extend outward from said edge zone of said glass carrier plate and protrude above the surface defining said front side of said glass carrier plate.

3. The glass unit of claim 1 wherein said holding bars each have a flat contact surface receiving said circumferential edge of said mirror plate, wherein said holding bars determine the distance (d) of said mirror plate from said glass carrier plate and the thickness (d) of said adhesive layer fixing said mirror plate to said glass carrier plate.

4. The glass unit of claim 3 wherein said contact surface is inclined from said edge zone to a free end.

5. The glass unit of claim 1 wherein said holding bars are tapered from said edge zone to a free end so that a cross section area of said holding bars being smaller in the area of said free ends than in the areas closer to said glass carrier plate.

6. The glass unit of claim 1 wherein said holding bars having a generally rectangular cross section.

7. The glass unit of claim 1 wherein free ends of said holding bars do not project beyond said mirror plate front side.

8. The glass unit of claim 1 wherein an overflow channel is disposed in said glass carrier plate in the area generally adjacent said edge zone for receiving excess adhesive.

9. A glass unit for a vehicle mirror assembly, said glass unit comprising:

a glass carrier plate that includes a front side, a back side and a circumferential edge zone;

a plurality of holding bars disposed on and distributed over said circumferential edge zone of said glass carrier plate, wherein said holding bars extending outward from said circumferential edge zone and generally perpendicular to said front side of said glass carrier plate;

a contact surface defined on each of said holding bars for receiving a circumferential edge of a mirror plate, wherein said contact surface is inclined in a direction outward from said circumferential edge zone so that said contact surface slopes upwardly to a free end of each of said holding bars; and

,

an overflow channel disposed in said glass carrier plate extending circumferentially around said glass carrier plate and generally adjacent to said circumferential edge zone.

10. The glass unit of claim 9 wherein said holding bars intersect with said front side of said glass carrier plate at said circumferential edge zone.

11. The glass unit of claim 9 wherein said contact surface is defined by a flat planer surface extending across at least a portion of said holding bars.

12. The glass unit of claim 9 wherein said holding bars taper in the direction of free ends.

13. The glass unit of claim 9 wherein said holding bars carry said mirror plate spaced above said front side of said glass carrier plate with an adhesive layer disposed there between fixing said mirror plate to said glass carrier plate.

14. The glass unit of claim 9 wherein free ends of said holding bars do not project beyond a mirror plate front side when said mirror plate is mounted to said glass carrier plate.
