| Closed Car Stiffness in Open Car Bodies SECTION A-A SECTION B-B The drawing shown here is of the body frame which is one of the features of the convertible coupes recently announced by Plymouth and Chrysler. It comprises side members and diagonals built up of channels welded together to form box sections. At the center the diagonals are welded to a deep box section to further add to the rigidity of the frame. The object of this body frame, which is rigidly bolted to the chassis frame, is to make up for the difference in the vertical stiffness of the ordinary open body and the conventional closed body.
