Abstract
Abstract An occupant detection system ( 10 ) for controlling the activation of an air bag inflator module ( 16 ) incorporates radar module ( 12 ), the activation of which is responsive to an activation sensor responsive to either the likelihood of a crash or to the likelihood of injury from the air bag inflator module ( 16 ) as a result of proximity thereto. In one embodiment, responsive to a potential crash, the air bag inflator module activates the radar module ( 12 ) for a period of time to sense if an occupant is within the at-risk zone of the air bag inflator module. In another embodiment, the activation of the radar module ( 12 ) is responsive to a continuously active range/proximity sensor ( 22 ). The air bag inflator is disabled if an occupant is detected with in the at-risk zone of the air bag inflator module ( 16 ).

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
124 words
A method of detecting an occupant in a vehicle and for controlling the actuation of a safety restraint system responsive thereto, comprising: a. detecting a condition for which the safety restraint system should not be deployed, wherein the operation of detecting a condition for which the safety restraint system should not be deployed comprises sensing the proximity of an occupant to a region within which said occupant is at risk of injury by the safety restraint system; b. controlling the activation of a sensor for sensing the position of an occupant responsive to said operation of detecting a condition for which the safety restraint system should not be deployed; and c. controlling the safety restraint system responsive to the sensed position of said occupant.
Claim 2
Independent Claim
124 words
A method of detecting an occupant in a vehicle and for controlling the actuation of a safety restraint system responsive thereto, comprising: a. detecting a condition for which the safety restraint system should not be deployed, wherein the operation of detecting a condition for which the safety restraint system should not be deployed comprises sensing the proximity of an occupant to a region within which said occupant is at risk of injury by the safety restraint system; b. controlling the activation of a sensor for sensing the position of an occupant responsive to said operation of detecting a condition for which the safety restraint system should not be deployed; and c. controlling the safety restraint system responsive to the sensed position of said occupant.
Claim 3
Dependent Claim
42 words
A method of detecting an occupant in a vehicle and for controlling the actuation of a safety restraint system responsive thereto in claim 1 , wherein the operation of sensing the proximity of an occupant to said region comprises sensing the occupant.
Claim 4
Dependent Claim
52 words
A method of detecting an occupant in a vehicle and for controlling the actuation of a safety restraint system responsive thereto as recited in claim 2 , wherein the operation of sensing the proximity sensor selected from the group consisting of a capactive sensor, a vision sensor, and a passive infrared sensor.
Claim 5
Independent Claim
151 words
A method of detecting an occupant in a vehicle and for controlling the actuation of a safety restraint system responsive thereto, comprising: a. sensing with a first sensor the proximity of an occupant to a region within which said occupant is at risk of injury by the safety restraint system; b. if said occupant is in proximity to a region so as to be at risk of injury by the safety restraint system, then in response to said proximity of said occupant, sensing with a second sensor that is normally inactive the position of said occupant; c. communicating said position to a controller for controlling the safety restraint system; and d. controlling the safety restraint system responsive to said position, wherein if said position corresponds to a position for which said occupant is at risk of injury by the safety restraint system, then reducing the power of the safety restraint system.
Claim 6
Independent Claim
151 words
A method of detecting an occupant in a vehicle and for controlling the actuation of a safety restraint system responsive thereto, comprising: a. sensing with a first sensor the proximity of an occupant to a region within which said occupant is at risk of injury by the safety restraint system; b. if said occupant is in proximity to a region so as to be at risk of injury by the safety restraint system, then in response to said proximity of said occupant, sensing with a second sensor that is normally inactive the position of said occupant; c. communicating said position to a controller for controlling the safety restraint system; and d. controlling the safety restraint system responsive to said position, wherein if said position corresponds to a position for which said occupant is at risk of injury by the safety restraint system, then reducing the power of the safety restraint system.
Claim 7
Dependent Claim
45 words
A method of detecting an occupant in a vehicle and for controlling the actuation of a safety restraint system responsive thereto as recited in claim 4 , wherein the operation of reducing the power of the safety restraint system comprises disabling the safety restraint system.
Claim 8
Dependent Claim
64 words
A method of detecting an occupant in a vehicle and for controlling the actuation of a safety restraint system responsive thereto as recited in claim 4 , further comprising the operation of disabling said second sensor responsive to a condition selected from the group consisting of the expiration of a period of time and the occurrence of said acceleration being less than a threshold.
