ABSTRACT:
A tailgate ramp extends the tailgate with three hinged panels (13, 14, 15) able to fold out to a co-planar position whereat each hinge (51, 55) is braced by a system of struts (21, 26) and cables (22, 25) against opening past 180.degree.. The cables (22, 25) and struts (21, 26) are arranged to permit the outermost panel (15) to fold into between the other two (13, 14) to collapse into a pack against the inner face of the tailgate. The system of cables (21, 26) at each hinge (51, 55) can be passed around sheaves (29-32, 37-40) at each side of the ramp in a single length to balance loads on the ramp.
