Abstract

An instrument panel projection apparatus is mounted on a pivotable steering column or the ceiling of the vehicle. A small steering wheel, preferably no more than twelve inches in diameter, is also mounted on the steering column. The instrument panel image is projected onto a reflection plate. The steering wheel, reflection plate and the instrument panel cluster are positioned so that the driver'"'"'s sight line for viewing the image of the instrument panel cluster is over the steering wheel. Further, when the steering column is pivoted or telescoped, the steering wheel and the instrument panel cluster are also pivoted and telescoped, so as to continue to provide a sight line for viewing the instrument cluster over the steering wheel. The projection apparatus may include a lens system with a magnifying lens to increase the size of the projected image.

Claims

1. In a vehicle having a steering column with a steering wheel mounted thereon and a front windshield, an operating condition display comprising:

an image source for projecting an image of information indicating vehicle operating conditions toward the windshield, said image source being mounted outside a line of sight of a driver through the windshield; and

a reflection plate positioned between the windshield and steering wheel to intercept and reflect the entire projected image of information over the steering wheel to the driver'"'"'s line of sight;

wherein said steering column is pivotable and further including a linkage between said reflection plate and said steering column arranged so that said reflection plate pivots with said steering column so as to maintain the reflection of the entire projected image over the steering wheel.

2. The display of claim 1 wherein said steering column telescopes in addition to being pivotable.

3. The display of claim 2 wherein said image source is mounted on said steering column adjacent to said steering wheel.

4. The display of claim 2 wherein said image source is mounted on a ceiling of the vehicle.

5. The display of claim 1 wherein said image source is mounted on said steering column adjacent to said steering wheel.

6. The display of claim 1 wherein said image source is mounted on a ceiling of the vehicle.

7. In a vehicle having a steering column with a steering wheel mounted thereon and a front windshield, an operating condition display comprising:

an image source for projecting an image of information indicating vehicle operating conditions toward the windshield, said image source being mounted outside a line of sight of a driver through the windshield; and

a reflection plate positioned between the windshield and steering wheel to intercept and reflect the entire projected image of information over the steering wheel to the driver'"'"'s line of sight;

wherein said steering column telescopes and further including a linkage between said reflection plate and said steering column arranged so as to maintain the reflection of the entire projected image over the steering wheel.

8. In a vehicle having a steering column with a steering wheel mounted thereon and a front windshield, an operating condition display comprising:

an image source for projecting an image of information indicating vehicle operating conditions toward the windshield, said image source being mounted outside a line of sight of a driver through the windshield, and

a reflection plate positioned between the windshield and steering wheel to intercept and reflect the entire projected image of information over the steering wheel to the driver'"'"'s line of sight;

wherein said steering column pivots and telescopes, and further including a linkage between said reflection plate and steering column arranged so that said reflection plate moves with said steering column so as to maintain the reflection of the entire projected image over the steering wheel.

9. In a vehicle having a steering column with a steering wheel mounted thereon and a front windshield, an instrument panel display comprising:

an image source for projecting an image of an instrument panel indicating at least one vehicle operating condition toward the windshield, said image source being mounted on said steering column outside a line of sight of a driver through the windshield,

a reflection plate positioned between the windshield and steering wheel to intercept and reflect the entire projected image over the steering wheel to the driver'"'"'s line of sight, said steering column being capable of at least one of pivotable and telescoping movement; and

a linkage between said reflection plate and said steering column to move said reflection plate as said steering column moves so as to maintain the reflection of the entire projected image over the steering wheel.

10. The display of claim 9 further comprising a lens system positioned between said image source and said reflecting plate.

11. The display of claim 10 wherein said lens system comprises a magnifying lens.

12. The display of claim 9 wherein said image source includes a liquid crystal display.

13. The display of claim 9 wherein said image source includes a cathode ray tube.

14. The display of claim 9 wherein said steering wheel is no greater in diameter than 12 inches.

15. The display of claim 9 in which the image source has a cross section form factor of substantially 5 inches wide by 2 inches in height.

16. The instrument panel display of claim 9 wherein said image source includes a liquid crystal display and further comprising a lens system positioned between said image source and said reflecting plate, said lens system including a magnifying lens.

17. The instrument panel display of claim 9 wherein said image source includes a cathode ray tube and further comprising a lens system positioned between said image source and said reflecting plate, said lens system including a magnifying lens.

18. The display of claim 9 wherein said image moves said reflecting plate to maintain the reflection of the entire projected image over said steering wheel at all positions of said steering column.

19. In a vehicle having a steering column with a steering wheel mounted thereon and a front windshield, an instrument panel display comprising:

an image source for projecting an image of an instrument panel indicating at least one vehicle operating condition toward the windshield, said image source being mounted on a ceiling of the vehicle and outside a line of sight of a driver through the windshield,

a reflection plate positioned between the windshield and steering wheel to intercept and reflect the entire projected image over the steering wheel to the driver'"'"'s line of sight, said steering column being capable of at least one of pivotable and telescoping movement; and

a linkage between said reflection plate and said steering column to move said reflection plate as said steering column moves so as to maintain the reflection of the entire projected image over the steering wheel.

20. The display of claim 19 wherein said image source includes a liquid crystal display and further including a lens system positioned between said image source and said reflecting plate, said lens system including a magnifying lens.
