Abstract: Disclosed is apparatus for anchoring, mounting, attaching or otherwise securing a seat belt to a plastic structure which forms part of or is connected to a vehicle body. The plastic structure includes two spaced plastic frame-like members which are adjacently disposed, each including an opening therein, with the axes of the openings aligned. The apparatus includes first and second mounting members which are connected together after the members have individually been positioned in the structure. A first mounting member has a flange which engages one of the frame-like members on its exterior side and extends through the opening of that frame-like member to the interior side of other frame-like member. The second mounting member is inserted through the opening in the other frame-like member and has a flanged portion which engages the exterior side of the second frame-like member, the first and second mounting members thereby sandwiching the second frame-like member.

Abstract: In a method of molding a large plastic structure which includes applying a vacuum to draw the molds together, injecting resin into the space between the molds while the vacuum is applied, maintaining the vacuum at least until the resin gels, removing the vacuum, allowing the molded structure to harden, removing the male mold and then removing the molded structure, molding is carried out on a moving production line without danger of disturbing the resin while gelling by disposing the molds on bogies and moving the bogies onto motor driven glide rollers at the point where the resin is injected, and the bogies transported on the glide roller drive until initial gelling has taken place.

Abstract: In a structure comprising an inner molded glass reinforced plastic body and an outer shell of sheet material the sheet material is affixed to the body by at least one in-fill panel, the panel bonded to the body and the sheet material attached to the SMC panel by a plurality of self threading fasteners.

Abstract: A door is mounted to hinge about a horizontal axis between a closed position and an open position. A torsion bar is mounted in pretensioned manner to bias the door from the closed position to the open position and to hold the door in the open position in a tensioned manner. The vehicle body is made of molded reinforced plastic while the hinges and mounting plates are metal.

Abstract: In order to maintain a vacuum at a plurality of molds on an assembly line, each mold has its own vacuum unit operating with compressed air and a plurality of molds are interconnected to supply compressed air in series to each of the molds.
