Abstract
A mattress is provided having an elongated foam base, a plurality of air sacks positioned above the foam base, and a longitudinally-extending manifold. Each air sack defines an interior region. The manifold includes an outer wall defining an interior region in fluid communication with a source of pressurized fluid and in fluid communication with the interior region of each air sack. The foam base and the plurality of air sacks cooperate to define a channel. The manifold is positioned in the channel and supported on top of the foam base.
Claims31
A mattress comprising:
- an elongated foam base,
- a plurality of air sacks positioned above the foam base, each air sack defining an interior region, and
- a longitudinally-extending manifold including an outer wall defining an interior region in fluid communication with a source of pressurized fluid and in fluid communication with the interior region of each air sack, the foam base being positioned below the manifold.
A mattress comprising:
- an elongated foam base,
- a plurality of air sacks positioned above the foam base, each air sack defining an interior region, and
- a longitudinally-extending manifold located between the plurality of air sacks and the foam base with the foam base supporting the manifold, the manifold including an outer wall defining an interior region in fluid communication with a source of pressurized fluid and in fluid communication with the interior region of each air sack.
A mattress comprising:
- an elongated foam base,
- a plurality of air sacks positioned to lie above the foam base, each air sack defining an interior region.
- a longitudinally-extending manifold located between the plurality of air sacks and the foam base, the manifold including an outer wall defining an interior region in fluid communication with a source of pressurized fluid and in fluid communication with the interior region of each air sack, and
- a plurality of flow control assemblies, each flow control assembly being associated with at least one air sack of the plurality of air sacks and each flow control assembly defining an interior region in fluid communication with the interior region of the manifold and the interior region of its respective sack so that each air sack is in fluid communication with the manifold, each flow control assembly including a check valve mounted in the conduit to prevent the flow of pressurized fluid from the interior region of each air sack to the interior region of the manifold.

A mattress comprising:
- a plurality of air sacks, each air sack including an outer walls having a top portion, a pair of side portions, and a bottom portion cooperating to defining an interior region and
- a longitudinally-extending manifold member including an outer wall having a top portion, a pair of side portions, and a bottom portion cooperating to define an interior region in fluid communication with a source of pressurized fluid and in fluid communication with the interior region of each air sack, the top portion of the manifold being positioned above the bottom portions of the air sacks.
A mattress comprising:
- a plurality of air sacks, the air sacks cooperating to define a channel and
- a longitudinally-extending manifold positioned in the channel defined by the air sacks, the longitudinally-extending manifold including an outer wall defining an interior region in fluid communication with a source of pressurized fluid and in fluid communication with the interior region of each air sack.
A mattress comprising:
- an elongated foam base,
- a plurality of air sacks positioned above the foam base, each of the air sacks having an outer wall defining an interior region, and
- a longitudinally-extending manifold including an outer wall having a top portion, a bottom portion, and a pair of spaced-apart side portions cooperating to define an interior region in fluid communication with a source of pressurized fluid and in fluid communication with the interior region of each air sack, the bottom portion of the manifold being positioned adjacent to the elongated foam base.
