Abstract
A rotational mattress has (a) a support surface and a rotating bladder object or (b) the support surface, the rotating bladder and a cushion material object. Depending on the embodiment used, the rotating bladder object and/or cushion material object has at least one longitudinal hinge; a longitudinal hinge extends from the object's head end toward the object's foot end. In one embodiment, the longitudinal hinge can be a shaped aperture and within the shaped aperture is a second cushion material. The second cushion material is less rigid than the cushion material.
Claims20
A rotating mattress comprising:
- a support surface;
- a rotating bladder positioned above at least a portion of the support surface, having a right bladder and a left bladder, the right bladder is interconnected to a first pump that provides a fluid to the right bladder, and the left bladder is interconnected to a second pump that provides fluid to the left bladder;
- a cushion material (a) positioned over the rotating bladder and the support surface, (b) has a head end, a foot end, a right side, a left side, a top surface and a bottom surface, (c) has a first longitudinal hinge (i) extending from the head end toward the foot end, and (ii) is parallel to and near the right side, (d) a second longitudinal hinge (i) extending from the head end toward the foot end, (ii) is parallel to and near the left side, and (iii) that is not the first longitudinal hinge;
- wherein when the cushion material is rotated by having the right rotatable bladder raise the right side above the left side, the cushion material's fulcrum point is at the second longitudinal hinge and
- wherein when the cushion material is rotated by having the left rotatable bladder raise the left side above the right side, the cushion material's fulcrum point is at the first longitudinal hinge.
