Abstract

Systems and methods for automatic seat adjustment, the systems and methods including a seat frame, a plurality of seat cushions coupled to the seat frame, a plurality of adjustable bladders enclosed within the plurality of seat cushions, and a plurality of sensors enclosed within the plurality of seat cushions. The systems and methods also including a memory for storing user data and a plurality of seat adjustment programs for controlling the at least one of the plurality of adjustable bladders. The systems and methods further including at least one controller coupled to the memory, the plurality of adjustable bladders, and the plurality of sensors, the at least one controller configured to modify at least one of the plurality of adjustable bladders based on feedback from at least one of the plurality of sensors, the user data, and the seat adjustable programs.

Claims (27)

1 . A seat comprising:

a frame;

a plurality of seat cushions;

a plurality of adjustable bladders positioned within the seat;

a plurality of sensors located within the seat;

a plurality of voice coils located within the seat, wherein each voice coil is associated on a one-to-one basis with an adjustable bladder of the plurality of adjustable bladders;

a memory for storing user data and a plurality of seat adjustment programs for controlling the plurality of adjustable bladders and the plurality of voice coils; and

an electronic processor coupled to the memory, the plurality of adjustable bladders, the plurality of voice coils, and the plurality of sensors, the electronic processor configured to control the plurality of adjustable bladders and the plurality of voice coils in accordance with the seat adjustment programs and based on the user data and feedback from at least one of the plurality of sensors;

wherein the plurality of adjustable bladders, the plurality of voice coils, or both the plurality of adjustable bladders and the plurality of voice coils is configured to provide a massaging output.

2 . The seat of claim 1 , wherein the plurality of seat cushions includes a seat base cushion, a back rest cushion, and a head rest cushion.

3 . The seat of claim 1 , further comprising a plurality of temperature controlling elements configured to supplement the massaging output by adjusting a temperature of the seat according to massage parameters.

4 . The seat of claim 3 , wherein the plurality of temperature controlling elements is configured to provide heat to warm a user of the seat prior to the user beginning an activity associated with the massaging output.

5 . The seat of claim 3 , wherein the plurality of temperature controlling elements is configured to cool a user of the seat after the user completing an activity associated with the massaging output.

6 . The seat of claim 1 , wherein the plurality of sensors includes a physiological sensor configured to measure a biometric signal that includes at least one of a group consisting of heart rate, heart rate variability (HRV), breathing rate, and combinations thereof; and

wherein the massaging output includes a biometric massage treatment configured to mimic the biometric signal and then be modified to be output according to a modified biometric signal that is adjusted based on a state of a user as determined based on the biometric signal.

7 . The seat of claim 1 , wherein the plurality of seat adjustment programs includes a static comfort module, and the electronic processor is configured to establish a seat contour.

8 . The seat of claim 7 , wherein the electronic processor is configured to

establish, via a seat adjustment subsystem, a contour of the seat based on a user's size, shape, and personal preferences.

9 . The seat of claim 8 , wherein establishing, via a seat adjustment subsystem, a contour of the seat includes adjusting a combination of bolsters, a lumbar support, the plurality of adjustable bladders, a seat recline, a seat height, and a seat angle.

10 . The seat of claim 7 , wherein the electronic processor is configured to assess a pressure between a user and the seat.

11 . The seat of claim 10 , where the electronic processor is configured to determine a total load measured by a plurality of pressure sensors prior to assessing the pressure between the user and the seat.

12 . The seat of claim 7 , wherein the plurality of sensors includes a plurality of pressure sensors located at a plurality of locations and wherein the electronic processor is configured to generate a map of pressure values based on pressures sensed by the plurality of pressure sensors.

13 . The seat of claim 12 , wherein the map of pressure values is stored in a user profile.

14 . The seat of claim 12 , wherein the pressure values are overlayed into a pressure grid representing regional body mapping zones of a human body model.

15 . The seat of claim 7 , wherein the electronic processor is configured to

control a pressure scan of the seat to establish an initial baseline pressure; and

establish, via a seat adjustment subsystem, an initial contoured static comfort configuration of the seat.
