Occupant Support with Multi-Modal Control
An adjustable bed ( 20 ) includes a base frame ( 30 ) and an occupant support system ( 32 ) operable in two or more modes of operation. A user control ( 90 ), which may be a rocker pedal ( 100 ) is capable of assuming at least two identities, each corresponding to one of the two or more modes of operation. A mode selector ( 122 ) allows a user to select an identity for the user control. Selection of the user control identity enables a user to use the user control to govern the mode of operation corresponding to the selected identity.
1 . An adjustable bed comprising:
a base frame;
an occupant support system operable in two or more modes of operation;
a user control capable of assuming at least two identities, each identity corresponding to one of the two or more modes of operation;
a selector for selecting an identity for the user control whereby selection of the user control identity enables the user control to govern the mode of operation corresponding to the selected identity.
2 . The bed of claim 1 wherein the two or more modes of operation are selected from the group consisting of an elevation mode, an inclination mode, a weigh mode, an upper body rotational mode, a leg contour mode, a profile mode, a length mode, a mattress firmness mode and a turn assist mode.
3 . The bed of claim 1 wherein the user control is at least one pedal.
4 . The bed of claim 1 wherein the user control is a single rocking pedal.
5 . The bed of claim 1 wherein the user control is a finger operated interface.
6 . The bed of claim 1 wherein the user control is capable of assuming exactly two identities, one of the two identities corresponding to an elevation mode of operation and the other of the two identities corresponding to an upper body rotational mode whereby selection of the elevation mode enables the user control to govern an elevation of the bed and selection of the upper body rotational mode enables the user control to govern angular orientation of an upper body section of the bed.
7 . The bed of claim 1 wherein the user control is capable of assuming exactly two identities, one of the two identities corresponding to an UP mode of operation and the other of the two identities corresponding to a DOWN mode whereby selection of the UP mode enables the user control to increase an elevation of the bed and an orientation angle of an upper body section of the bed and selection of the DOWN mode enables the user control to decrease the elevation of the bed and the orientation angle of the upper body section.
8 . The bed of claim 6 wherein the user control is a pair of controls, a first member of the pair enabling a decrease in the elevation of the bed when the elevation mode is selected and a second member of the pair enabling an increase in the elevation of the bed when the elevation mode is selected, and the first member of the pair enabling a decrease in the angular orientation of the bed when the upper body rotational mode is selected and the second member of the pair enabling an increase in the angular orientation of the bed when the upper body rotational mode is selected.
9 . The bed of claim 8 wherein each member of the pair of controls is a pedal.
10 . The bed of claim 1 wherein the user control is capable of assuming exactly three identities, one of the three identities corresponding to an elevation mode of operation, a second identity corresponding to a leg profile mode of operation and a third identity corresponding to an upper body rotational mode of operation whereby selection of the elevation mode enables the user control to govern an elevation of the bed, selection of the leg profile mode enables the user control to govern angular orientation of thigh and calf deck sections of the bed, and selection of the upper body rotational mode enables the user control to govern angular orientation of an upper body section of the bed.
