Seat track assembly for a motor vehicle having an integrated position sensor
First Claim
1. A seat track assembly for a seat of a motor vehicle having a floor and an airbag, said seat track assembly comprising:
- a stationary rail fixedly secured to the floor;
a movable rail fixedly secured to the seat and slidably engaged with said stationary rail to move the seat therealong, said movable rail extending along a length between a forward position and a rearward position;
a shunt defining an elongated body extending along a portion of said length of said movable rail; and
a sensor fixedly secured to said stationary rail and disposed adjacent said shunt to produce a position signal indicating a position of said sensor relative to said shunt whereby said sensor and said shunt are disposed within said stationary and movable rails to be protected thereby.

Abstract
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.

25. A method for controlling a deployment rate of an airbag of a motor vehicle having a seat and a seat track assembly including a stationary rail, a sensor disposed within the stationary rail, a movable rail, and a shunt disposed within the movable rail, the method comprising the steps of:
-
sensing a magnetic field using the sensor and the shunt;
producing a position signal indicating the position of the seat based on the magnetic field sensed by the sensor; and
varying the deployment rate of the airbag based upon the position signal. - View Dependent Claims (26, 27, 28)
