Vehicle seat assembly having a vehicle occupant sensing system with a biasing pad
First Claim
1. A vehicle occupant sensing system for a vehicle seat assembly, said vehicle occupant sensing system comprising:
- a plurality of emitters;
a plurality of sensors, wherein each of said sensors is operatively paired to one of said emitters and adapted to detect relative distance therebetween, and thereby detect a condition of the vehicle seat assembly; and
a biasing pad having a top surface and a bottom surface, said top surface adapted to be disposed below a lower surface of a seat cushion of the vehicle seat assembly so that said top surface of said biasing pad is adapted to be biased into contact with the lower surface of the seat cushion of the vehicle seat assembly, being deflectable in response to deflection of the seat cushion, said biasing pad supporting said plurality of emitters and said plurality of sensors such that said operatively paired emitters and sensors are biased away from each other and such that said operatively paired emitters and sensors are supported so that they are movable toward and away from the other.

Abstract
A vehicle occupant sensing system for a vehicle seat assembly that includes at least one emitter and at least one sensor operable to detect relative distance between the sensor and the emitter to thereby detect a condition of the vehicle seat assembly. The vehicle occupant sensing system also includes a biasing pad adapted so as to be disposed below a seat cushion of the vehicle seat assembly so as to deflect in response to deflection of the seat cushion. The biasing pad supports at least one of the emitter and the sensor such that the emitter and the sensor are biased away from each other and such that one of the emitter and the sensor are supported for movement toward and away from the other.

8. A vehicle seat assembly comprising:
-
a seat cushion having an upper surface and a lower surface; and a vehicle occupant sensing system that includes a plurality of emitters, a plurality of sensors, wherein each of said sensors is operatively paired to one of said emitters detecting a relative distance therebetween, thereby detecting a condition of the vehicle seal assembly, and a biasing pad having a top surface and a bottom surface, said top surface disposed below the lower surface of said seat cushion of the vehicle seat assembly so that said top surface of said biasing pad is biased into contact with said lower surface of said seat cushion, deflecting in response to deflection of said seat cushion, said biasing pad supporting said plurality of emitters and said plurality of sensors such that said operatively paired emitters and sensors mare biased away from each other and such that said operatively paired emitters and sensors are supported so that they are moveable toward and away from the other. - View Dependent Claims (9, 10, 11, 12, 13, 14)

15. A vehicle occupant sensing system for detecting a condition of a vehicle seat assembly, said vehicle occupant sensing system comprising;
-
a plurality of emitters; a plurality of sensors, wherein each of said sensors is operatively paired to one of said emitters and adapted to detect relative distance therebetween, and thereby detect a condition of the vehicle seat assembly; and a biasing pad having a plurality of cavities formed therein and a top surface, said top surface adapted to be disposed below a lower surface of a seat cushion of the vehicle seat assembly so that said top surface of said biasing pad is adapted to be biased into contact with a lower surface of the seat cushion, said biasing pad supporting said plurality of emitters and said plurality of sensors such that said operatively paired emitters and sensors are supported so that they are movable toward and away from the other within said cavities, said biasing pad biasing said emitters away from said sensors. - View Dependent Claims (16, 17, 18, 19, 20)
