  • Truck bed and method of manufacture with improved rear sill member
    Patent number: 5575525
    Abstract: An improved vehicle bed assembly, and process of manufacture, which involves formation of the floor pan (31) by roll forming, with the floor pan (31) having strengthening ribs (34) extending longitudinally throughout the entire length of the floor pan so as to terminate at the front and rear free edges thereof. The rear free edge (36) of the floor pan (31) cooperates with a rear sill member (32, 32') which has rib-end defining projections (47, 99) formed thereon and cooperating with the ends of the ribs (34) on the floor pan (31) for closing off the ribs and creating a transition to a flat horizontal surface defined on the rear sill member. The rib ends of the rear sill member preferably have guide portions (49, 102) which nest into and are fixedly secured, as by spot welding, to the rearward ends of the ribs defined on the floor pan.
