Claim 11

The sun visor of claim 6, wherein said adjusting device further comprises a bearing supported on the vehicle for supporting said strap; said strap being pivotally connected to said bearing at a location along said strap remote from said second visor body pivot.

Claim 12

The sun visor of claim 9, wherein said strap comprises a generally U-shaped shaft having a first leg which is pivotally attached to said visor body at said second visor body pivot and having another leg which is pivotally attached to said bearing.

Claim 13

The sun visor of claim 10, further comprising a detent spring embedded in said visor body; said shaft first leg engages said detent spring.

Claim 14

The sun visor of claim 6, wherein said guiding means comprises a slide means attached to the vehicle body, said visor body first pivot comprises means on said visor body for slidably engaging said slide means for sliding therealong as said visor body pivots about said first pivot.

Claim 15

The sun visor of claim 12, wherein said slide means includes a slot and said means on said visor body at said first pivot includes a projection extending from said visor body into said slide means slot.

Claim 16

The sun visor of claim 13, wherein with said sun visor body rear moved away from the windshield and said visor body projection moved rearwardly on said slide means slot, said strap forms an acute angle with said slide means slot at both said bearing and said second pivot.

Claim 17

The sun visor of claim 12, wherein the distance between said first and second pivots is approximately the length of said strap between said bearing and said visor body second pivot.

Claim 18

The sun visor of claims 12 or 15, wherein the length of said slide means slot approximates the distance between said first and said second pivots.

Claim 19

The sun visor of claim 13, wherein said visor body has side edges between said front and said rear thereof and said projection extends from a said side edge of said visor body; said slide means being along said side edge of said visor body.

Claim 20

The sun visor of claim 13, wherein said slide means slot is periodically constricted throughout its length thereby to impede the movement of said projection through said slide means slot.

Claim 21
