Abstract

Abstract A pair of g-responsive first parallel sensors and a pair of g-responsive second parallel sensors provided in a motor vehicle. An inflator is mounted on a steering wheel of the vehicle and cruise operating switches are provided on the steering wheel. An air bag circuit is from a first source to a ground passing through the first parallel sensors, a pair of first parallel leads in a connector provided on the steering wheel, inflator, a pair of second parallel leads in the connector, and the second parallel sensors. A cruise operating circuit is from a second source to the ground passing through a lead in the connector, cruise switches, and the second parallel leads, so that the second parallel leads are common to the air bag circuit and the cruise operating circuit.

Claims Analysis

Total Claims: 3
Claim 1
Independent Claim 189 words
An air bag system for a motor vehicle comprising: a pair of g-responsive first parallel sensors provided in the motor vehicle at a position; a pair of g-responsive second parallel sensors provided in the motor vehicle at another position; an inflator provided on a steering wheel of the vehicle; switches provided on the steering wheel for operating an operating system mounted on the vehicle; a connector having a plurality of leads and mounted on the steering wheel so as to permit the rotation of the steering wheel, keeping electrical connection between components on the steering wheel and components mounted on the vehicle; an air bag circuit from a first source to a ground passing through the first parallel sensors, a pair of first parallel leads in the connector, inflator, a pair of second parallel leads in the connector, and the second parallel sensors; an operating circuit from a second source to the ground passing through a lead in the connector, said switches, and said second parallel leads; a pair of diodes provided in the air bag circuit so as to separate the operating circuit from the air bag circuit
Claim 2
Dependent Claim 189 words
An air bag system for a motor vehicle comprising: a pair of g-responsive first parallel sensors provided in the motor vehicle at a position; a pair of g-responsive second parallel sensors provided in the motor vehicle at another position; an inflator provided on a steering wheel of the vehicle; switches provided on the steering wheel for operating an operating system mounted on the vehicle; a connector having a plurality of leads and mounted on the steering wheel so as to permit the rotation of the steering wheel, keeping electrical connection between components on the steering wheel and components mounted on the vehicle; an air bag circuit from a first source to a ground passing through the first parallel sensors, a pair of first parallel leads in the connector, inflator, a pair of second parallel leads in the connector, and the second parallel sensors; an operating circuit from a second source to the ground passing through a lead in the connector, said switches, and said second parallel leads; a pair of diodes provided in the air bag circuit so as to separate the operating circuit from the air bag circuit
