Abstract:
The bed frame (10) includes a base frame (12) and an articulating upper frame (40). The base frame (12) includes a head end, a foot end, and oppositely disposed, longitudinally extending sides. The articulating upper frame (40) comprises an upper body section (42), a seat section (44), a thigh section (46), and a lower leg section (48). The articulating upper frame (40) is mounted on the base frame (12) for longitudinal shifting of the articulating upper frame (40) relative to the base frame (12). A first drive assembly (50) for raising and lowering the upper body section (42) includes linkage connected to the upper body section (42) such that, tilting movement of the upper body section (42) shifts the articulating upper frame (40) longitudinally relative to the base frame (12). A second drive assembly (52) for raising and lowering the thigh section (46) includes linkage connected to the lower leg section (48) such that, when the thigh section (46) tilts upwardly, the lower leg section (48) tilts downwardly.
