1. A bed for supporting a person comprising:
- a support platform coupled to a bed frame and having first and second panels with upwardly facing support surfaces, one longitudinal edge of the first panel positioned substantially parallel to and adjacent to a longitudinal edge of the second panel; and
an articulating seat joint assembly coupling the first panel to the second panel, said assembly varying the relative distance between the edges of the panels as the relative angle between the panels is varied, said joint assembly including;
a) a variable length rod assembly pivotally connected between the first and second panels whereby the first and second panels are rotated relative to one another as the length of the rod assembly is changed; and
b) a separation-varying hinge assembly for altering the vertical and horizontal distances between the adjacent edges as said longitudinal edges of the panels are rotated about an axis substantially coincident with the hip joint of the person supported on the bed.
