Occupant restraint system with seat position sensor
First Claim
1. A deployable passenger restraint system for an automotive vehicle comprising:
- an occupant seat mounted on a seat track for adjustable movement in at least a longitudinal direction, the seat track having a movable rail attached in a slidable relationship with a stationary rail mounted to a vehicle floor;
a deployable restraint;
a deployable mechanism for deploying the restraint;
deployable restraint processor means for receiving and processing a plurality of restraint deployment signals and for controlling the deployment mechanism; and
a seat position sensor comprising;
a generally L-shaped flange adapted to be mounted along a predetermined length of a flange side of the movable rail, the flange attached upside down with a horizontal leg attached on a first end to a flange side of the movable rail and a second end of the horizontal leg attached to a downturned leg; and
a magnetic sensor adapted to be mounted to the stationary rail on a sensor side adjacent the flange side for sensing presence of the flange and relaying a signal representative of seat position to the deployable restraint processor means, wherein the magnetic sensor has a support member extending from a sensor side of the stationary rail and an upwardly oriented U-shaped sensor member mounted to the support member for receiving the flange therethrough.

Abstract
A deployable passenger restraint system for an automotive vehicle has an occupant seat mounted on a seat track for adjustable movement in a longitudinal direction, the seat track having a movable rail in slidable relationship with the stationary rail mounted to the vehicle floor. The system includes a deployable restraint mounted in a forward location of the vehicle, a deployment mechanism for deploying the restraint, a deployment restraint processor for receiving and processing restraint deployment signals and for controlling the deployment mechanism, and a seat position sensor. The seat position sensor has a stepped flange adapted to be mounted along a predetermined length of a flange side of the movable rail, and a magnetic sensor adapted to be mounted to the stationary rail on a sensor side adjacent the flange side for sensing presence of the flange and relaying a single representative of seat position to the deployment processor. The magnetic sensor generates a single representing seat position in three zones, including a first zone represented by a first flange section having a first height, a second zone represented by a second flange section having a second height, and a blank section represented by that portion of the seat track not covered by a flange section.

6. A deployable passenger restraint system for an automotive vehicle comprising:
-
an occupant seat mounted on a seat track for adjustable movement in at least a longitudinal direction, the seat track having a movable rail attached in a slidable relationship with a stationary rail mounted to a vehicle floor; a deployable restraint; a deployable mechanism for deploying the restraint; a deployable restraint processor for receiving and processing a plurality of restraint deployment signals and for controlling the deployment mechanism; and a multi-zone seat position sensor comprising; a sensor flange mounted along a predetermined length of a flange side of the movable rail, the sensor flange having at least two sections along a length thereof with varying vertical heights, the sensor flange attached upside down with a horizontal leg attached on a first end to a flange side of the movable rail and a second end of the horizontal leg attached to a downturned leg; and a magnetic sensor mounted to the stationary rail on a sensor side adjacent the flange side for sensing for sensing position of the flange relative thereto and generating a signal representative of seat position to the deployment processor means, wherein the magnetic sensor has a support member extending from a sensor side of the stationary rail and an upwardly oriented U-shaped sensor member mounted to the support member for receiving the sensor flange therethrough.
