Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
111 words
A method of disabling an airbag system for a seating position within a motor vehicle, the airbag system comprising an airbag door, the method comprising the steps of: a) providing to a roof above the seating position one or more capacitive coupling occupant sensors; b) detecting presence or absence of an occupant of the seating position using the one or more capacitive coupling occupant sensors; c) disabling the airbag system if the seating position is unoccupied; d) detecting proximity of an occupant to the airbag door if the seating position is occupied; and e) disabling the airbag system if the occupant is closer to the airbag door than a predetermined distance.
Claim 2
Independent Claim
111 words
A method of disabling an airbag system for a seating position within a motor vehicle, the airbag system comprising an airbag door, the method comprising the steps of: a) providing to a roof above the seating position one or more capacitive coupling occupant sensors; b) detecting presence or absence of an occupant of the seating position using the one or more capacitive coupling occupant sensors; c) disabling the airbag system if the seating position is unoccupied; d) detecting proximity of an occupant to the airbag door if the seating position is occupied; and e) disabling the airbag system if the occupant is closer to the airbag door than a predetermined distance.
Claim 3
Dependent Claim
31 words
The method of claim 1 additionally comprising the step of modifying airbag deployment parameters to adjust inflation force of the airbag according to proximity of the occupant to the airbag door.
Claim 4
Dependent Claim
50 words
The method of claim 1 wherein the providing step comprises providing two capacitive coupling sensors, and the detecting proximity step comprises the steps of providing voltage output values of the capacitive coupling sensors to a data processor and comparing the voltage output values against predetermined values to determine occupant position.
Claim 5
Dependent Claim
32 words
The method of claim 1 wherein the providing step comprises providing one capacitive coupling sensor forward of a midpoint of the seating position and one capacitive coupling sensor aft of the midpoint.
Claim 6
Independent Claim
110 words
An apparatus for disabling an airbag system for a seating position within a motor vehicle, the airbag system comprising an airbag door, the apparatus comprising: one or more capacitive coupling occupant sensors proximate a roof above the seating position; means for detecting presence or absence of an occupant of the seating position using said one or more capacitive coupling occupant sensors; means for disabling the airbag system if the seating position is unoccupied; means for detecting proximity of an occupant to the airbag door if the seating position is occupied; and means for disabling the airbag system if the occupant is closer to the airbag door than a predetermined distance.
Claim 7
Independent Claim
110 words
An apparatus for disabling an airbag system for a seating position within a motor vehicle, the airbag system comprising an airbag door, the apparatus comprising: one or more capacitive coupling occupant sensors proximate a roof above the seating position; means for detecting presence or absence of an occupant of the seating position using said one or more capacitive coupling occupant sensors; means for disabling the airbag system if the seating position is unoccupied; means for detecting proximity of an occupant to the airbag door if the seating position is occupied; and means for disabling the airbag system if the occupant is closer to the airbag door than a predetermined distance.
Claim 8
Dependent Claim
30 words
The apparatus of claim 5 additionally comprising means for modifying airbag deployment parameters to adjust inflation force of the airbag according to proximity of the occupant to the airbag door.
Claim 9
Dependent Claim
54 words
The apparatus of claim 5 wherein said one or more capacitive coupling occupant sensors comprises two capacitive coupling sensors, and said means for detecting proximity comprises means for providing voltage output values of said capacitive coupling sensors to a data processor and comparing the voltage output values against predetermined values to determine occupant position.
Claim 10
Dependent Claim
34 words
The apparatus of claim 5 wherein the one of said capacitive coupling sensors is forward of a midpoint of the seating position and one of said capacitive coupling sensors is aft of the midpoint.
Claim 11
Dependent Claim
215 words
A motor vehicle air bag system for inflation and deployment of an air bag in front of a passenger in a motor vehicle during a collision, said motor vehicle having a passenger compartment for at least one passenger in said motor vehicle, said passenger compartment having an interior roof and a passenger seat for said passenger, said air bag system comprising: an air bag; inflation means connected to said air bag for inflating said air bag with a gas; passenger sensor means, mounted adjacent to said interior roof, for continuously sensing position of said passenger with respect to said passenger compartment, and for generating electrical output indicative of said position of said passenger; analog processor means, electrically connected to said passenger sensor means and to said inflation means, for comparing and performing an analysis of said electrical output from said passenger sensor means, and for activating said inflation means to inflate and deploy said air bag when said analysis indicates that said vehicle is involved in a collision and that deployment of said air bag would likely reduce a risk of serious injury to said passenger which would exist absent deployment of said air bag and likely would not present an increased risk of injury to said passenger resulting from deployment of said air bag.
Claim 12
Dependent Claim
215 words
A motor vehicle air bag system for inflation and deployment of an air bag in front of a passenger in a motor vehicle during a collision, said motor vehicle having a passenger compartment for at least one passenger in said motor vehicle, said passenger compartment having an interior roof and a passenger seat for said passenger, said air bag system comprising: an air bag; inflation means connected to said air bag for inflating said air bag with a gas; passenger sensor means, mounted adjacent to said interior roof, for continuously sensing position of said passenger with respect to said passenger compartment, and for generating electrical output indicative of said position of said passenger; analog processor means, electrically connected to said passenger sensor means and to said inflation means, for comparing and performing an analysis of said electrical output from said passenger sensor means, and for activating said inflation means to inflate and deploy said air bag when said analysis indicates that said vehicle is involved in a collision and that deployment of said air bag would likely reduce a risk of serious injury to said passenger which would exist absent deployment of said air bag and likely would not present an increased risk of injury to said passenger resulting from deployment of said air bag.
