A seat track assembly for a seat of a motor vehicle having a floor and an
airbag. The seat track assembly includes a stationary rail fixedly
secured to the floor. The seat track assembly also includes a movable
rail fixedly secured to the seat and slidably engaged with the stationary
rail to move the seat therealong. The movable rail extends along a length
between a forward position and a rearward position. A shunt defining an
elongated body extends along a portion of the length of the movable rail.
A sensor is fixedly secured to the stationary rail and disposed adjacent
the shunt to produce a position signal indicating a position of the
sensor relative to the shunt. The sensor and the shunt are disposed
within the stationary and movable rails to be protected thereby.
