Abstract

A seat assembly may include a seat, a first bladder assembly connected to the seat, a second bladder assembly connected to the seat, and/or an electrical control unit (ECU) configured to independently control the first bladder assembly and the second bladder assembly. The ECU may be configured to maintain a level of inflation of the first bladder assembly to provide a hugging effect to a user of the seat while inflating and deflating the second bladder assembly to guide breathing of said user.

First claim

What is claimed is:

1. A seat assembly, including:
a seat;
a first bladder assembly connected to the seat;
a second bladder assembly connected to the seat;
an electrical control unit (ECU) configured to independently control the first bladder assembly and the second bladder assembly; and
a biomedical sensor connected with the ECU;
wherein the ECU is configured to adjust or maintain a level of inflation of the first bladder assembly to provide a hugging effect to a user of the seat while inflating and deflating the second bladder assembly to guide breathing of said user;
the ECU is configured to sense a breathing pattern of said user via the biomedical sensor;
the ECU is configured to determine if the breathing pattern is irregular; and
if the breathing pattern is irregular, the ECU is configured to automatically activate the first bladder assembly and the second bladder assembly to reduce irregularities in the breathing pattern of said user.

2. The seat assembly of claim 1 , wherein the second bladder assembly is disposed to substantially align with a neck and/or shoulders of said user.

3. The seat assembly of claim 1 , including a fluid source in fluid communication with the first bladder assembly and the second bladder assembly;
wherein the ECU is configured to control the fluid source to inflate and deflate the first bladder assembly and the second bladder assembly.

4. The seat assembly of claim 3 , wherein the fluid source includes a fluid pump.

5. The seat assembly of claim 1 , wherein the seat includes one or more bolsters, and a bladder of the first bladder assembly is disposed in at least one of the one or more bolsters.

6. The seat assembly of claim 1 , wherein the seat includes a seat base and a seat back;
the seat base includes a first bolster and a second bolster;
the seat back includes a third bolster and a fourth bolster;
the first bladder assembly includes a first bladder, a second bladder, a third bladder, and a fourth bladder;
the first bladder and the second bladder are disposed at least partially in the first bolster and the second bolster, respectively; and
the third bladder and the fourth bladder are disposed at least partially in the third bolster and the fourth bolster, respectively.

7. The seat assembly of claim 6 , wherein the ECU is configured to maintain the level of inflation for the first bladder, the second bladder, the third bladder, and the fourth bladder of the first bladder assembly to provide the hugging effect while guiding breathing of the user via the second bladder assembly.

8. The seat assembly of claim 6 , including a fluid pressure sensor having a first sensor portion, a second sensor portion, a third sensor portion, and a fourth sensor portion;
wherein the first sensor portion is configured to sense a pressure of the first bladder;
the second sensor portion is configured to sense a pressure of the second bladder;
the third sensor portion is configured to sense a pressure of the third bladder;
the fourth sensor portion is configured to sense a pressure of the fourth bladder; and
maintaining the level of inflation includes inflating and deflating the first bladder, the second bladder, the third bladder, and/or the fourth bladder such that each of the first bladder, the second bladder, the third bladder, and the fourth bladder are within a pressure range.

9. The seat assembly of claim 1 , including a massage assembly connected to the seat;
wherein the massage assembly is connected with the ECU; and
the ECU is configured to automatically activate the massage assembly to massage said user to reduce irregularities in the breathing pattern of said user while (i) adjusting or maintaining the level of inflation of the first bladder assembly to provide the hugging effect, and (ii) inflating and deflating the second bladder assembly to guide breathing.

10. The seat assembly of claim 9 , wherein the massage assembly includes one or more massage bladders; and
the ECU is configured to inflate and deflate the one or more massage bladders to massage said user to reduce irregularities in the breathing pattern of said user.

11. The seat assembly of claim 10 , wherein the ECU is configured to control a fluid source connected to the first bladder assembly, the second bladder assembly, and the one or more massage bladders.

12. A seat assembly, including:
a seat;
a first bladder assembly disposed at least partially in the seat;
a second bladder assembly disposed at least partially in the seat;
a biomedical sensor configured to sense a breathing pattern of a user of the seat;
a massage assembly including one or more massage actuators disposed at least partially in the seat; and
an electrical control unit (ECU) connected to the biomedical sensor;
wherein the ECU is configured to:
automatically and independently control the first bladder assembly, the second bladder assembly, and the massage assembly to reduce irregularities in the breathing pattern of said user;
determine if the breathing pattern sensed via the biomedical sensor is irregular; and
automatically activate the first bladder assembly and to maintain a level of inflation of the first bladder assembly to provide a hugging effect to said user when the breathing pattern is irregular.

13. The seat assembly of claim 12 , where the ECU is configured to maintain the level of inflation of the first bladder assembly to provide the hugging effect while inflating and deflating the second bladder assembly to provide a guided breathing pattern for said user.

14. A method of operating a seat assembly including a seat, a first bladder assembly, and a second bladder assembly, the method including:
sensing a breathing pattern of a user occupying the seat via a biomedical sensor;
determining if the breathing pattern of said user includes irregularities via an electronic control unit (ECU);
inflating one or more bladders of the first bladder assembly;
maintaining a level of inflation of the one or more bladders; and
inflating and deflating the second bladder assembly to provide a simulated breathing pattern for said user to reduce irregularities in the breathing pattern of said user.

15. The method of claim 14 , wherein inflating and deflating the second bladder assembly includes the ECU automatically controlling a fluid source to inflate and deflate the second bladder assembly while controlling the fluid source to maintain the level of inflation of the one or more bladders of the first bladder assembly.

16. The method of claim 14 , including:
wherein inflating the first bladder assembly includes automatically inflating the first bladder assembly if the breathing pattern is irregular; and
inflating and deflating the second bladder assembly includes automatically inflating and deflating the second bladder assembly if the breathing pattern is irregular.

17. The method of claim 14 , including inflating and deflating one or more massage bladders of a massage assembly to prove a massaging effect to said user to reduce irregularities in the breathing pattern of said user.

18. The method of claim 17 , including deactivating the first bladder assembly, the second bladder assembly, and/or the massage assembly when irregularities of the breathing pattern have been reduced below a threshold.
