Abstract
Abstract Locking mechanism for a pedestal mounted seat is actuated by a spring biased handle which is mounted on the seat and which moves with the seat and carries an eccentric cam and guide member. In one position of adjustment, an outer tube carried by the seat is free to rotate about an inner tube carried by a floor mounted pedestal until the seat is in its aligned forward position at which point the guide member is moved into a slot in the inner tube. When the seat is in its forward position with the guide member in the slot, movement of the handle will rotate the eccentric cam into progressively greater contact with portions of the outer surface of the inner tube which are immediately adjacent the slot so as to prevent any wobbling taking place between the two tubes.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
199 words
In a rotatable seat for a motor vehicle having an outer tubular member attached to the seat frame and a telescoped inner tubular member attached to a base, the improvement comprising bracket means affixed to said outer tubular member, shaft means carried by said bracket means, cam means and detent means carried by said shaft, handle means on said shaft means for rotating said shaft, cam and detent means, a first aperture means formed in said inner tube and a second aperture means formed in said outer tube, said second aperture means being larger than said first aperture means and positioned relative to said first aperture means so that when the seat is in its driving position the first aperture means is positioned centrally of the second aperture means and aligned with said detent means whereby rotation of said handle means will cause said detent means to move into or out of said first aperture means and will cause said cam means to move into or out of evertightening engagement with portions of said inner tube located immediately adjacent said first means so as to force portions of said inner and outer tubes into binding contact with each other.
