25. A seat restraint buckle and tension sensing assembly for a seat restraint system in a vehicle comprising:
-
a buckle assembly having a housing for receiving a portion of a latch plate of the seat restraint system, said buckle assembly including a movable latch member having one end contacting said housing and extending upwardly to another end, said latch member including a latch portion disposed between the ends thereof and having a generally arcuate shape, at least one spring contacting said latch member and said housing for urging said latch portion upwardly, at least one first magnet disposed on said latch portion, and at least one first Hall effect sensor fixed to said housing and cooperating with said at least one first magnet; and
a tension sensing assembly disposed in said housing and comprising a movable actuator cooperable with the belt webbing, at least one second magnet mounted to said actuator, and at least one second Hall effect sensor mounted to said housing, said actuator moving said at least one second magnet relative to said at least one second Hall effect sensor to change an output of said at least one second Hall effect sensor for sensing a tension level in the seat restraint system.
