A unibody style automobile has bumper attachment pads for a crash bar and bumper cover assembly of conventional configuration. Removal of these bumper components provides access to these pads for a load carrier or beam that defines two coupling connections for a frame selected from a plurality of frames, each designed for a different load. All the frames have one fixed slide bolt received in one of the two sockets in the beam. A second bolt provides a very secure attachment point for each of these frames.

1. In a motor vehicle having bumper attachment pads provided in spaced relationship in the vehicle, the improvement comprising:a support beam having spaced support lands constructed and arranged to fit the spaced attachment pads in the vehicle body, said beam having at least two rearwardly open sockets arranged below said lands and also spaced horizontally apart below and between said support lands,a load carrying frame having at least one forwardly projecting primary slide bolt received in at least one of said sockets,a secondary bolt movable independently of said primary slide bolt and received in a second of said at least two sockets whereby said frame is adapted to support a load to be carried by the vehicle. 2. The combination of claim 1 wherein said frame is selected from a plurality of frames, each of which frames of said plurality is specifically designed to carry a different load. 3. The combination of claim 1 wherein said spaced attachment pads of said support beam are so constructed and arranged so to support the vehicle bumper in a manner that obscures said support beam except for the sockets which project outwardly of the vehicle below the bumper. 4. The combination of claim 1 wherein said primary slide bolt is rotatably received in said at least one socket, said slide bolt and socket having complementary mating surfaces so that relative rotation therebetween prevents said slide bolt from sliding movement in said socket when assembled therein. 5. The combination of claim 1 wherein said load carrying frame has said primary slide bolt provided in fixed relationship thereto, said secondary slide bolt being movably mounted in said frame and separately lockable in said second socket. 6. The combination of claim 1 wherein said support beam lands are spaced from one another by a dimension T, and wherein said sockets are spaced from one another by a dimension in the range of T/2 and T/4. 7. The combination of claim 1 wherein said support beam is of elongated configuration, and has a flanged cross-sectional shape to enhance its strength, and wherein said lands of said support beam are offset upwardly of said elongated beam, said sockets being defined as depending struts which are offset downwardly of said elongated beam. 8. In a vehicle of unibody construction having a bumper assembly that includes a crash bar mounted to spaced attachment pads in the vehicle body, the improvement comprising;a beam having spaced support lands constructed and arranged to fit the spaced attachment pads, said beam having at least two socket openings arranged below said spaced support lands;at least one protecting bolt received by one of said socket openings and adapted to support a frame selected from a plurality of frames, each frame being constructed and arranged so that it will accommodate at least one article of predetermined size and shape to be transported, said socket opening defining a radially inwardly projecting pin, and said projecting bolt defining a cam slot for providing a bayonet type connection between said socket opening and said projecting bolt. 9. The combination according to claim 8 further including a second projecting bolt received in another of said two socket openings, at least one of said bolts being rotatable relative said frame for securing said frame in a fixed position relative said beam. 10. The combination according to claim 9, wherein said projecting bolts have cam slots, and said sockets have pins to provide a bayonet connection to secure said frame. 11. The combination according to claim 10 wherein said one projecting bolt is mounted in said frame, and said second bolt is rotatably received in said frame. 12. The combination according to claim 10, wherein said second projecting bolt is not mounted in said frame.
