Abstract

An occupant detection system for a vehicle including a seat assembly and a mounting device. The mounting device includes a first member connected to the seat assembly, a second member connectable to the vehicle and connected to the first member at a first point, a floating joint located at a second point engageable with the seat assembly and with the vehicle, and a load sensor located on one of the first member and a second member between the first point and the second point. A compressing force tending to compress the seat assembly toward the vehicle travels through the load sensor, while a pulling force tending to pull the seat assembly from the vehicle travels through the floating joint.

Claims

1. An occupant detection system for a vehicle, comprising:

a seat assembly; and

a mounting device including a first member connected to said seat assembly, a second member connectable to the vehicle and connected to said first member at a first point, a floating joint located at a second point engageable with said seat assembly and with the vehicle, and a load sensor located on one of said first member and said second member between the first point and the second point;

such that a compressing force tending to compress said seat assembly toward the vehicle travels through said load sensor, while a pulling force tending to pull said seat assembly from the vehicle travels through said floating joint.

2. The occupant detection system of claim 1 wherein said seat assembly includes a track, and said first member is connected to said track.

3. The occupant detection system of claim 1 wherein said floating joint is connected to said first member.

4. The occupant detection system of claim 3 wherein said floating joint is connected to said seat assembly.

5. The occupant detection system of claim 1 wherein said floating joint is engageable with said second member.

6. The occupant detection system of claim 5 wherein said second member defines a clearance about said floating joint, such that during the compressive force said second member is isolated from said floating joint.

7. The occupant detection system of claim 6 wherein said floating joint includes an enlarged head, such that during the pulling force said enlarged head of said floating joint is engaged with said second member.

8. A mounting device of an occupant detection system for a vehicle with a seat assembly, said mounting device comprising:

a first member connectable to the seat assembly;

a second member connectable to the vehicle and connected to said first member at a first point;

a floating joint located at a second point engageable with the seat assembly and with the vehicle; and

a load sensor located on one of said first member and said second member between the first point and the second point;

such that a compressing force tending to compress the seat assembly toward the vehicle travels through said load sensor, while a pulling force tending to pull the seat assembly from the vehicle travels through said floating joint.

9. The mounting device of claim 8 wherein said first member is connectable to a track of the seat assembly.

10. The mounting device of claim 8 wherein said floating joint is connected to said first member.

11. The mounting device of claim 10 wherein said floating joint is connectable to the seat assembly.

12. The mounting device of claim 8 wherein said floating joint is engageable with said second member.

13. The mounting device of claim 12 wherein said second member defines a clearance about said floating joint, such that during the compressive force said second member is isolated from said floating joint.

14. The mounting device of claim 13 wherein said floating joint includes an enlarged head, such that during the pulling force said enlarged head of said floating joint is engaged with said second member.

15. A method for providing an occupant detection system in a vehicle, comprising:

providing a seat assembly;

providing a mounting device including a first member, a second member, a floating joint, and a load sensor;

connecting the first member to the seat assembly;

connecting the second member to the vehicle and to the first member at a first point;

locating a floating joint at a second point engageable with the seat assembly and with the vehicle; and

locating a load sensor on one of the first member and the second member between the first point and the second point such that a compressing force tending to compress the seat assembly toward the vehicle travels through the load sensor, while a pulling force tending to pull the seat assembly from the vehicle travels through the floating joint.

16. The method of claim 15 wherein said providing a seat assembly includes providing a seat assembly with a track;

and wherein said connecting the first member includes connecting the first member to the track.

17. The method of claim 15 wherein said locating the floating joint includes connecting the floating joint to the first member.

18. The method of claim 17 wherein said locating the floating joint also includes connecting the floating joint to the seat assembly.

19. The method of claim 15 wherein said locating the floating joint includes locating the floating joint at the second point engageable with the second member.

20. The method of claim 19 wherein said providing a mounting device includes providing a mounting device including the second member which defines a clearance about the floating joint such that during the compressive force the second member is isolated from the floating joint.

21. The method of claim 20 wherein said providing a mounting device includes providing a mounting device including a floating joint with an enlarged head such that during the pulling force the enlarged head of the floating joint is engaged with the second member.
