Abstract

A system and method that comprises a plurality of inflatable tubes is provided. The plurality of inflatable tubes comprises a first tube set and a second tube set. The plurality of inflatable tubes is configured to provide a pressure distribution to an object supported by the plurality of inflatable tubes. The first tube set is configured to be inflated and deflated at a predetermined time interval to shift the pressure distribution.

First claim

What is claimed is:

1 . A repositioning system, comprising:
a plurality of inflatable tubes, wherein the plurality of inflatable tubes comprises a first tube set and a second tube set, wherein the plurality of inflatable tubes is configured to provide a pressure distribution to an object supported by the plurality of inflatable tubes, wherein the first tube set is configured to be inflated and deflated at a predetermined time interval to shift the pressure distribution.

2 . The repositioning system of claim 1 , further comprising:
a soft foam cushion supported by the plurality of inflatable tubes.

3 . The repositioning system of claim 1 , further comprising:
a soft foam cushion provides a continuous plane that supports an occupant as the first tube is inflated and.

4 . The repositioning system of claim 1 , wherein the second tube set is configured to be inflated and deflated in conjunction with the first tube set at the predetermined time interval to shift the pressure distribution.

5 . The repositioning system of claim 1 , further comprising:
a seat structure configured to support the plurality of inflatable tubes.

6 . The repositioning system of claim 1 , further comprising:
a compressor configured to provide air to the plurality of inflatable tubes in accordance with the predetermined time interval.

7 . The repositioning system of claim 1 , wherein the repositioning system is in a seat of an aircraft.

8 . A repositioning method, comprising:
providing a pressure distribution to an object supported by a plurality of inflatable tubes, the plurality of inflatable tubes comprising a first tube set and a second tube set; and shifting the pressure distribution by inflating and deflating the first tube set at a predetermined time interval.

9 . The repositioning method of claim 8 , further comprising:
supporting a soft form cushion by the plurality of inflatable tubes.

10 . The repositioning method of claim 8 , further comprising:
providing a continuous plane that supports an occupant as the first tube is inflated by a soft foam cushion.

11 . The repositioning method of claim 8 , wherein shifting the pressure distribution comprises:
inflating and deflating the second tube set in conjunction with the first tube set at the predetermined time interval.

12 . The repositioning method of claim 8 , further comprising:
supporting the plurality of inflatable tubes by a seat structure.

13 . The repositioning method of claim 8 , further comprising:
providing air to the plurality of inflatable tubes in accordance with the predetermined time interval by a compressor.

14 . The repositioning method of claim 8 , wherein a seat of an aircraft comprises the plurality of inflatable tubes.
