First Claim
1. A vehicle seat sensing system for detecting a presence of an unrestrained vehicle occupant on a vehicle seat cushion comprising:
- a plurality of sensor assemblies in spaced relation to one another and disposed adjacent a lower surface of said vehicle seat cushion, wherein each of said plurality of sensor assemblies variably sense a displacement of said vehicle seat cushion; and
a summing circuit disposed in proximity to said plurality of sensor assemblies for summing sensed signals from said plurality of sensor assemblies, said summing circuit providing a summed output signal indicative of a presence of a vehicle occupant; and
wherein said summed output signal is output exterior of said vehicle seat for determining whether said vehicle occupant is seated on said vehicle seat cushion.

Abstract
A vehicle seat sensing system is provided for detecting a presence of an unrestrained vehicle occupant on a vehicle seat cushion. A plurality of sensor assemblies are in spaced relation to one another and disposed adjacent a lower surface of said vehicle seat cushion. Each of the plurality of sensor assemblies variably sense a displacement of the vehicle seat cushion. A summing circuit disposed in proximity to the plurality of sensor assemblies is provided for summing sensed signals from the plurality of sensor assemblies. The summing circuit provides a summed output signal indicative of a presence of a vehicle occupant. The summed output signal is output exterior of the vehicle seat for determining whether the vehicle occupant is seated on the vehicle seat cushion.

14. A method for detecting an unrestrained vehicle occupant seated on a vehicle seat cushion of a vehicle, said method comprising the steps of:
-
providing a plurality of sensor assemblies in spaced relation to one another disposed adjacent a lower surface of said vehicle seat cushion, each of said plurality of sensor assemblies output a sensed signal for variably sensing a displacement of a respective region of said vehicle seat cushion;
summing each sensed output signal from said plurality of sensor assemblies;
outputting a summed output signal exterior to said vehicle seat to be used for determining said presence of said vehicle occupant. - View Dependent Claims (15, 16, 17, 18, 19, 20)
