1. A bed comprising:
- a deck having at least one section that is orientation adjustable about a laterally extending, longitudinally translatable axis that translates a prescribed distance in response to a change in orientation of the deck section;
a mattress assembly including at least one volumetrically adjustable element associated with the orientation adjustable deck section, the element comprised of a set of N inflated and deflatable bladders adapted to change the thickness of a portion of the mattress assembly adjacent to the deck section in a direction nonparallel to the orientation of the section; and
a controller adapted to command bladder inflation as a function of occupant characteristics and the orientation of the orientation adjustable deck section as specified in an inflation schedule set forth below.

Abstract
A bed comprises a deck having at least one section that is orientation adjustable about a laterally extending, longitudinally translatable axis and a mattress assembly including at least one volumetrically adjustable element associated with the orientation adjustable deck section. The volumetrically adjustable element is adapted to change the thickness of a portion of the mattress assembly adjacent to the deck section in a direction nonparallel to the orientation of the section and in response to a change in orientation of the deck section.

24. A bed comprising:
-
a deck having at least one section that is orientation adjustable about a laterally extending, longitudinally translatable axis that translates a prescribed distance in response to a change in orientation of the deck section; a mattress assembly including a volumetrically adjustable element comprised of multiple inflatable bladders associated with the orientation adjustable deck section and distributed in a direction substantially perpendicular to the orientation of the deck section, the bladders adapted to change the thickness of a portion of the mattress assembly adjacent to the deck section in a direction nonparallel to the orientation of the section; and a controller for commanding inflation of a selected quantity of the bladders in response to the change in orientation of the deck section thereby regulating the change of thickness. - View Dependent Claims (25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45)

46. A bed comprising:
-
a deck having an upper body section which is orientation adjustable about a laterally extending, longitudinally translatable axis that translates a prescribed distance in response to a change in orientation of the upper body deck section; and a mattress assembly including at least one volumetrically adjustable element comprised of multiple inflatable bladders associated with the upper body deck section, the element adapted to change the thickness of a portion of the mattress assembly adjacent to the deck section in a direction nonparallel to the orientation of the section and; a controller for regulating the change of thickness by commanding inflation of a selected quantity of the bladders in response to the change in orientation of the deck upper body section. - View Dependent Claims (47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60, 61, 62, 63, 64, 65, 66)
