ROTATABLE DRIVE CONNECTION THAT REDUCES CHATTER
First Claim
1. A rotatable drive connection comprising:
- a first component including an aperture having a plurality of corners; and
a second component including an end portion having a plurality of edges, the end portion of the second component being smaller than the aperture of the first component, wherein the end portion of the second component is disposed within the aperture of the first component such that at least one of the edges of the end portion is always biased into engagement with at least one of the corners of the aperture throughout a full rotation of the first and second components.

9. A rotatable drive connection comprising:
-
a first component including an aperture having a plurality of corners; and a second component including an end portion having a plurality of edges, the end portion of the second component being disposed within the aperture of the first component such that the end portion engages a leading edge of the aperture and a tip of the end portion engages an inner surface of the aperture at a location that is axially spaced from and generally opposite the leading edge, wherein at least one of the edges of the end portion is always biased into engagement with at least one of the corners of the aperture throughout a full rotation of the first and second components. - View Dependent Claims (10, 11, 12, 13, 14)

15. A power seat assembly comprising:
-
an adjustable seat frame; a drive mechanism mounted to the seat frame; an adjustment mechanism mounted to the seat frame and adapted to actuate movement of the seat frame, wherein at least one of the drive mechanism and the adjustment mechanism includes a rotatable component having an aperture that defines a plurality of corners extending along the aperture; and a flexible driveshaft interconnected between the drive mechanism and the adjustment mechanism, the flexible driveshaft including at least one end portion defining a plurality of edges extending along the end portion; wherein the end portion is smaller than the aperture and is received within the aperture such that at least one of the edges of the end portion is biased into engagement with at least one of the corners of the aperture throughout a full rotation of the rotatable component. - View Dependent Claims (16, 17, 18, 19, 20)
