Abstract
Abstract A mirror assembly for a vehicle comprises a housing (12) and a mirror assembly (18, 20) mounted therein. The housing includes attachment means (30, 32, 34, 36) for supporting the mirror (18, 20) in the housing (12). Support means (22) pivotably mounts the mirror assembly (10, 18) to the attachment means (30, 32, 34, 36). The support means (22) includes first and second arm means (40, 42, 44, 46) which mount the support means (22) to the attachment means (30, 32, 34, 36). The first arm means (44, 46) are mounted in tension and the second arm means (40, 42) are mounted in compression. The prestressing of the first and second arm means (40, 42, 44, 46) serves to reduce vibration of the mirror relative to the vehicle and thereby substantially reduce blurring of images on the mirror.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
111 words
A mirror assembly for a vehicle comprising: a housing; a mirror; attachment means in said housing for supporting said mirror in said housing; support means for pivotably mounting said mirror to said attachment means; said support means including first and second prestressed arm means for mounting said support means each said arm means having a pair of opposing arms, to said attachment means, said first arm means being mounted in tension and said second arm means being mounted in compression; wherein said prestressing of said first and second arm means serves to reduce vibration of the mirror relative to the vehicle and thereby substantially reduce blurring of images on said mirror.
Claim 2
Dependent Claim
111 words
A mirror assembly for a vehicle comprising: a housing; a mirror; attachment means in said housing for supporting said mirror in said housing; support means for pivotably mounting said mirror to said attachment means; said support means including first and second prestressed arm means for mounting said support means each said arm means having a pair of opposing arms, to said attachment means, said first arm means being mounted in tension and said second arm means being mounted in compression; wherein said prestressing of said first and second arm means serves to reduce vibration of the mirror relative to the vehicle and thereby substantially reduce blurring of images on said mirror.
Claim 3
Dependent Claim
37 words
The mirror assembly of claim 1 wherein said attachment means includes stud means for engaging one of said first and second arm means and flange means for engaging the other of said first and second arm means.
Claim 4
Dependent Claim
19 words
The mirror assembly of claim 2 including fastening means for securing said one arm means to said stud means.
Claim 5
Dependent Claim
32 words
The mirror assembly of claim 3 wherein said fastening means comprises a threaded fastener received in a bore in said stud means and passing through an aperture in said one arm means.
Claim 6
Dependent Claim
63 words
The mirror assembly of claim 4 wherein said one arm means is said second arm means and the distance between the centerlines of the bores in said stud means is less than the distance between the centerlines of the apertures in said one arm means so that said one arm means are compressed when the arm means are secured to said stud means.
Claim 7
Dependent Claim
21 words
The mirror assembly of claim 2 wherein the other of said arm means include lip means for engaging said flange means.
Claim 8
Dependent Claim
55 words
The mirror assembly of claim 4 wherein said other arm means is said first arm means and the distance between said lip means is greater than the distance between said flange means so that said arm means are prestressed in tension and said housing is compressed when the lip means and flange means are engaged.
Claim 9
Dependent Claim
22 words
The mirror assembly of claim 1 wherein said first and second arm means extend from a central hub of said support means.
Claim 10
Dependent Claim
20 words
