Abstract
A seat assembly may include a seat, a seat actuator, a sensor assembly, and an electrical control unit (ECU). The seat actuator may be configured to adjust the seat. The sensor assembly may be connected to the seat and may be configured to detect a pressure applied to the seat. The ECU may be operatively connected to the seat actuator and the sensor assembly. The ECU may be configured to reduce soft tissue stress in soft tissue of a user via adjusting the seat with the seat actuator.
Claims19
A seat assembly, comprising:
- a seat including a plurality of bolsters, the plurality of bolsters including a first bolster and a second bolster;
- a bladder assembly including a plurality of bladders, the plurality of bladders including a first bolster bladder associated with the first bolster and a second bolster bladder associated with the second bolster;
- a sensor assembly connected to the seat, the sensor assembly detecting pressure applied to the seat;
- a seat actuator;
- and
- an electrical control unit (ECU) operatively connected to the seat actuator and the sensor assembly;
- wherein the ECU reduces soft tissue stress in soft tissue of a user of the seat via adjusting the seat with the seat actuator;
- wherein adjusting the seat with the seat actuator includes operating the seat actuator to adjust an inflation level of at least one of the first bolster bladder and the second bolster bladder to adjust an amount of lateral force applied to said user to reduce lateral bulging of said soft tissue;
- wherein the sensor assembly detects a plurality of characteristics of said user;
- wherein the ECU generates a model for at least one portion of a body of said user based on the plurality of characteristics of said user;
- wherein the ECU identifies one or more capillaries of said user that are at least partially closed via utilizing the model;
- and
- wherein adjusting the seat with the seat actuator includes adjusting the seat to facilitate opening of the one or more capillaries.

A seat assembly, comprising:
- a seat;
- a seat actuator;
- a sensor assembly connected to the seat, the sensor assembly detecting pressure applied to the seat;
- and
- an electrical control unit (ECU) operatively connected to the seat actuator and the sensor assembly;
- wherein the ECU:
- generates a plurality of pressure distribution maps of respective localized pressure of a plurality of regions of the seat at different points in time during a period of time;
- detects a peak pressure area in at least some of the plurality of pressure distribution maps;
- assembles the plurality of pressure distribution maps into a pressure distribution stack;
- tracks the detected peak pressure area over the pressure distribution stack and analyzes changes in the detected peak pressure area;
- and
- reduces soft tissue stress in soft tissue of a user of the seat via adjusting the seat with the seat actuator to reduce the respective localized pressure in the detected peak pressure area.
