Patent
CA 2055671
A bed - Figure 1 - comprises a profiling mattress frame. Backrest 42 is arranged to be lifted by actuator 58 via a crank 56, and thighrest 46 similarly by actuator 60. Legrest 48 is freely pivoted to the thighrest. The angles of the parts are sensed and maintained in proportion by control means, so that as if for example the backrest angle 42 is steepened, the thighrest 46 is also raised in proportion but to less extent, taking the legrest 48 with it.
