| Abstract: |
An air deflector blade for vehicles and the like is pivotally movable between a substantially vertical orientation and a substantially horizontal orientation in response to the wind velocity created thereupon. The pivotal mounting enables the blade to rotate selectively between the vertical and horizontal positions in proportion to the speed of the vehicle.

Having, thus, described the invention what is claimed is:
1. A velocity responsive deflector blade assembly comprising:
- (a) a deflector blade,
- (b) a mounting assembly for each end of the blade, each assembly comprising:
- (1) a blade cap, the end of the deflector blade being journalled thereonto, said blade cap having a slot formed therein, the end of the blade being journalled into the slot and frictionally retained therewithin;
- (2) a casting having means defining a ledge, the blade cap normally seating on the ledge; and
- (3) means for self aligningly and pivotally mounting the blade cap to the casting, and
- wherein the blade cap pivotally rotates about the pivotal mounting means relative to the casting in response to the velocity of air impinging against the deflector blade.
