Claims
- 1. A seat belt tension sensor assembly comprising:
a housing; a slider slidably received within said housing, said slider being configured for movement between a first position and a second position within said housing; a first and second magnet associated with said slider for slidable movement therewith, said first and said second magnets being positioned side by side with opposite polarization; a hall effect device being fixed relative to said housing and protruding between said first and said second magnet when said slider is in said second position, said hall effect device being configured to produce an output voltage signal, said output voltage signal being indicative of a seat belt tension of a seat belt as applied to said sensor assembly; and a biasing member for providing an urging force to said slider, said urging force urging said slider into said first position.
- 2. The seat belt sensor assembly of claim 1 wherein said housing further comprises a hook to accept a latch of said seat belt.
- 3. The seat belt sensor assembly of claim 2 wherein said hook further comprises a stop device.
- 4. The seat belt sensor of claim 2 wherein said slider is adapted for receiving force from said latch.
- 5. The seat belt sensor assembly of claim 1 wherein said hall effect sensor produces a discrete signal.
- 6. The seat belt sensor of claim 1 wherein said output voltage signal changes as a function of tension of the movement of said slider.
- 7. The seat belt sensor assembly of claim 1 wherein said biasing member is a plurality of springs.
- 8. A seat belt tension sensor assembly comprising:
a housing; a slider slidably received within said housing, said slider being configured for movement between a first position and a second position within said housing; a first and second magnet associated with said slider for slidable movement therewith, said first and said second magnets being positioned side by side with opposite polarization; a hall effect device being fixed relative to said housing and protruding between said first and said second magnet when said slider is in said second position, said hall effect device being configured to produce an output voltage signal, said output voltage signal being indicative of a seat belt tension of a seat belt as applied to said sensor assembly; a biasing member for providing an urging force to said slider, said urging force urging said slider into said first position; and wherein said hall effect device provides said output voltage signal to a control unit, said control unit communicates said tension of said seat belt to a safety restraint device.
- 9. The seat belt tension sensor assembly of claim 8 wherein said safety restraint device is a light display.
- 10. The seat belt tension sensor assembly of claim 8 wherein said safety restraint device is an airbag.
- 11. The seat belt tension sensor assembly of claim 8 wherein said safety restraint device is a pre-tensioner.
- 12. A seat belt tension sensor assembly comprising:
a housing; a slider slidably received within said housing, said slider being configured for movement between a first position and a second position within said housing; a first and second magnet associated with said slider for slidable movement therewith, said first and said second magnets being positioned side by side with opposite polarization; a hall effect device being fixed relative to said housing and protruding between said first and said second magnet when said slider is in said second position, said hall effect device being configured to produce an output voltage signal, said output voltage signal being indicative of a seat belt tension of a seat belt as applied to said sensor assembly; a biasing member for providing an urging force to said slider, said urging force urging said slider into said first position; wherein said hall effect device provides said output voltage signal to a control unit, said control unit communicates said tension of said seat belt to a safety restraint device; and a switch being fixed relative to said housing configured to detect a magnetic field created from said first and said second magnet when said slider is in said first position.
- 13. The seat belt sensor tension assembly of claim 12 wherein said housing further comprises a hook to accept a latch of said seat belt.
- 14. The seat belt sensor of claim 12 wherein said slider is adapted for receiving force from said latch.
- 15. The seat belt sensor of claim 14 wherein said switch reacts relative to position of said latch.
