Abstract
A mechanical engagement system such as a seat belt assembly includes a housing and a slider slidably received within the housing, the slider is configured for movement between a first position and a second position within the housing. A single magnet is associated with the slider for slidable movement therewith while a hall effect device is fixed relative to the housing. The hall effect device is fixed relative to the housing and aligned with at the single magnet when the slider is in the second position. The hall effect device is configured to generate an output signal indicative of a latch condition of the mechanical engagement system as applied to the sensor assembly.
Claims31
A seat belt 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 single magnet associated with said slider for slidable movement therewith;
- and
- a hall effect device being fixed relative to said housing and substantially aligned with said magnet when said slider is in said second position, said hall effect device being configured to generate an output signal, said output signal being indicative of a latch condition of the seat belt as applied to said sensor assembly.
A seat belt 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 single magnet associated with said slider for slidable movement therewith;
- and
- a hall effect device being fixed relative to said housing and aligned with said magnet when said slider is in said second position, said hall effect device being configured to generate an output signal, said second output signal being indicative of a latch condition of the seat belt as applied to said sensor assembly;
- wherein said hall effect device provides said output voltage signal to a control unit, said control unit communicates said latch condition of said seat belt to a safety restraint device.
A method to determine positive latch engagement of a mechanical engagement system, the method comprising:
- configuring a slider to be slidably received within a housing, said slider being configured for movement between a first position and a second position within said housing;
- associating a single magnet with said slider for slidable movement therewith;
- and
- fixedly disposing a hall effect device relative to said housing and aligned with said magnet when said slider is in said second position, said hall effect device being configured to generate an output signal, said output signal being indicative of a latch condition of the mechanical engagement system as applied to said sensor assembly.
