Abstract

A system that generates a dynamic seating body pressure distribution data includes a seat and a stimulus applying mechanism that is adapted to apply a stimulus to the seat. A human biofidelic manikin is provided on the seat. A seat pressure distribution sensor array is responsive to the human biofidelic manikin for generating a dynamic seating body pressure distribution data when the stimulus applying mechanism applies a stimulus to the seat.

Claims

1. A system for generating a dynamic seating body pressure distribution data comprising:

a seat having a plurality of areas of interest, each area of interest having a unique natural resonant frequency;

a stimulus applying mechanism that is adapted to apply a stimulus of varying frequency to the seat;

a human biofidelic manikin provided on the seat; and

a seat pressure distribution sensor array having a plurality of individual pressure sensors, each individual pressure sensor positioned at one of the plurality of areas of interest;

wherein the seat pressure distribution sensor array is responsive to the human biofidelic manikin for generating a dynamic seating body pressure distribution data when the stimulus applying mechanism applies a stimulus of varying frequency to the seat;

wherein each area of interest reacts differently in response to the frequency of the stimulus applied to the seat by the stimulus applying mechanism;

wherein changes in pressure exerted on each area of interest in the seat by the human biofidelic manikin in response to the stimulus of varying frequency applied to the seat over time are measured by the individual pressure sensors, the measurements defining the dynamic seating body pressure distribution data.

2. The system defined in claim 1 wherein the seat pressure distribution sensor array is provided on a surface of the seat, and wherein the human biofidelic manikin provided on the seat pressure distribution sensor array.

3. The system defined in claim 1 wherein the seat pressure distribution sensor array is provided within the seat, and wherein the human biofidelic manikin provided on the seat.

4. The system defined in claim 1 wherein the seat includes a seat bottom and a seat back, the human biofidelic manikin is provided on one of the seat bottom and the seat back, and the seat pressure distribution sensor array is responsive to the human biofidelic manikin on the one of the seat bottom and the seat back.

5. The system defined in claim 1 wherein the seat includes a seat bottom and a seat back, the human biofidelic manikin is provided on both of the seat bottom and the seat back, and the seat pressure distribution sensor array is responsive to the human biofidelic manikin on both of the seat bottom and the seat back.

6. The system defined in claim 1 wherein the individual pressure sensors are arranged in a two-dimensional array.

7. The system defined in claim 1 wherein the dynamic seating body pressure distribution data is expressed as a two dimensional array of individual pressure measurement regions.

8. A method for generating a dynamic seating body pressure distribution data comprising the steps of:

(a) providing a seat having a plurality of areas of interest, each area of interest having a unique natural resonant frequency;

(b) providing a seat pressure distribution sensor array having a plurality of individual pressure sensors, each individual pressure sensor positioned at one of the plurality of areas of interest;

(c) providing a human biofidelic manikin on the seat;

(d) applying a stimulus of varying frequency to the seat; and

(e) generating a dynamic seating body pressure distribution data when the stimulus of varying frequency is applied to the seat;

wherein the seat pressure distribution sensor array is responsive to the human biofidelic manikin for generating a dynamic seating body pressure distribution data when the stimulus of varying frequency is applied to the seat;

wherein each area of interest reacts differently in response to the frequency of the stimulus applied to the seat; and

wherein changes in pressure exerted on each area of interest in the seat by the human biofidelic manikin in response to the stimulus of varying frequency applied to the seat over time are measured by the individual pressure sensors, the measurements defining the dynamic seating body pressure distribution data.

9. The method defined in claim 8 wherein step (a) is performed by providing a seat pressure distribution sensor array on a surface of the seat, and wherein step (c) is performed by providing the human biofidelic manikin on the seat pressure distribution sensor array.

10. The method defined in claim 8 wherein step (a) is performed by providing a seat pressure distribution sensor array within the seat.

11. The method defined in claim 8 wherein step (a) is performed by providing a seat that includes a seat bottom and a seat back, step (c) is performed by providing the human biofidelic manikin on one of the seat bottom and the seat back, and step (e) is performed by generating a dynamic seating body pressure distribution data when the stimulus of varying frequency is applied to the one of the seat bottom and the seat back.

12. The method defined in claim 8 wherein step (a) is performed by providing a seat that includes a seat bottom and a seat back, step (c) is performed by providing the human biofidelic manikin on both of the seat bottom and the seat back, and step (e) is performed by generating a dynamic seating body pressure distribution data when the stimulus of varying frequency is applied to both of the seat bottom and the seat back.

13. The method defined in claim 8 wherein the individual pressure sensors are arranged in a two-dimensional array.

14. The method defined in claim 8 wherein step (e) is performed by expressing the dynamic seating body pressure distribution data as a two dimensional array of individual pressure measurement regions.
