Abstract: A vehicle sunroof for installation into a roof of a vehicle includes a sunroof panel and a sunroof frame. The sunroof frame is attached to the vehicle roof through the use of rotating cam members which are disposed within the sunroof frame and which are rotatable such that cam lobes pressingly engage an inner surface of the vehicle roof or a pre-trim ring to clamp the vehicle roof between a lip of the sunroof frame and the rotating cam members. A method for attaching the sunroof frame to a vehicle includes the steps of forming an opening in the roof of a vehicle, then attaching the pre-trim ring to a lower surface of the edge of the opening. The sunroof frame is then inserted into the opening, with the sunroof frame having at least one rotatable cam members thereupon. The rotatable cam member is then rotated, to engage the pre-trim ring or the vehicle roof with an engagement surface of the cam, thereby clamping the roof between the lip of the sunroof frame and the cam or the pre-trim ring.

Abstract: A gravity traction apparatus including an adjustable and collapsible A-frame with a transversely extending beam member at the top. Pivotally mounted on the beam member is a generally flat thigh-pad structure which has a T-shaped knee-stop member extending upwardly and rearwardly from adjacent the rear portion thereof.Stop means are provided to limit the pivotal movement of the thigh-pad structure between an inoperative position in which it is in a generally vertical position and a user is in a standing position at the rear of the frame, and an operative position in which it is generally horizontal and the user is supported thereon and hanging over the beam member with his head in a downward position.
