PCT No. PCT/GB97/01429 Sec. 371 Date Nov. 26, 1998 Sec. 102(e) Date Nov. 23, 1998 PCT Filed May 23, 1997 PCT Pub. No. WO97/45040 PCT Pub. Date Dec. 4, 1997Motorized adjustment of the configuration of a bed in its support of a user in an automatic "sleep" mode is controlled to establish the bed in state A (FIG. 3) pre-selected for sleeping on the side, or state B (FIG. 2) pre-selected for sleeping on the back, in dependence upon whether the user's shoulder as sensed by a pressure pad (26) is within a recess (27) of the mattress (1). A motor unit (8) adjusts the bed-configuration by inclining bed-base sections (4,5) under commands from a controller (15 FIG. 4) that for the "sleep" mode operates in conjunction with an auxiliary unit (16 FIG. 4) coupled to the pad (26). Delays for changeovers between states A and B and the changeover threshold are set by controls (31, 33 and 34) of the auxiliary unit (16). |
