Vehicle seat position sensing apparatus
First Claim
1. An apparatus for use in a vehicle having a seat frame for supporting a vehicle occupant and a floor pan for supporting the seat frame for movement relative to the floor pan, said apparatus comprising:
- a deflection member for connection with the seat frame for movement with the seat frame, said deflection member having a first deflection surface;
a sensor lever for connection with the floor pan, said sensor lever having a second deflection surface for engaging said first deflection surface of said deflection member and for deflecting as the seat frame moves relative to the floor pan, the amount of deflection of said sensor lever changing as the seat frame moves relative to the floor pan; and
a sensor for sensing the deflection of said sensor lever and providing an output signal indicative of the amount of deflection of said sensor lever.

Abstract
An apparatus (10) is used in a vehicle having a seat frame (20) for supporting a vehicle occupant and a floor pan (4) for supporting the seat frame (20) for movement relative to the floor pan (4). The apparatus (10) includes a deflection member (50), a sensor lever (70), and a sensor (79). The deflection member (50) connects to the seat frame (20) for movement with the seat frame (20). The deflection member (50) has a first deflection surface (51). The sensor lever (70) connects to the floor pan (4). The sensor lever (70) has a second deflection surface (71) for engaging the first deflection surface (51) of the deflection member (50) and for deflecting as the seat frame (20) moves relative to the floor pan (4). The amount of deflection of the sensor lever (70) changes as the seat frame (20) moves relative to the floor pan (4). The sensor (79) senses the deflection of the sensor lever (70) and provides an output signal indicative of the amount of deflection of the sensor lever (70).

13. An apparatus for use in a vehicle having a seat for a vehicle occupant and a floor pan for supporting the seat, said apparatus comprising:
-
an actuatable vehicle occupant protection device;
a vehicle seat frame for supporting a vehicle occupant on the seat, said vehicle seat frame being movable linearly in a forward direction of vehicle travel and in a rearward direction of vehicle travel relative to the floor pan through an adjustment path;
a mechanism for sensing each position of the seat relative to the floor pan in said adjustment path and providing a first unique output signal indicative of each position;
a sensor for sensing the weight of the vehicle occupant in the seat and providing a second output signal indicative of the weight of the vehicle occupant; and
a controller for receiving said first unique output signal and said second output signal, said controller controlling actuation of said vehicle occupant protection device in accordance with said first and second output signals.
