Abstract
A multistage gas generator for an air bag has ignition devices 51 and 61 respectively disposed in the combustion chambers 50 and 60 provided in a housing 3. A lead wire 9 for sending an ignition signal to each igniter 8 is provided with a connector 10. The connector 10 is provided with a defining element 17 for specifying unique combination of connection between the respective ignition signal-outputting unit and the respective igniters 8.
Claims15
A multistage type air bag apparatus, comprising:
- a multistage gas generator for an air bag including, in a housing, a first igniter and a second igniter, selectively initiated by activation signals, provided adjacent to one another;
- a first lead wire having a first connector, provided on a first end thereof, for selectively connecting the first lead wire to the first igniter, the first lead wire extending from a side peripheral portion of the first connecter such that when the first connector is attached to the first igniter, the first lead wire extends only in a predetermined direction on an imaginary plane substantially perpendicular to a central axis of the housing without bending the first lead wire;
- and
- a second lead wire having a second connector, provided on a first end thereof, for selectively connecting the second lead wire to the second igniter, the second lead wire extending from a side peripheral portion of the second connector such that when the second connector is attached to the second igniter, the second lead wire extends only in the predetermined direction and only on the imaginary plane without bending the second lead wire.

A multistage gas generator for an air bag, comprising:
- a housing including a gas discharge port;
- a first igniter attached to said housing and selectively initiated by activation signals, said first igniter selectively receiving a first connector provided at one end of a first lead wire, the first lead wire extending from a side peripheral portion of the first connector such that when the first connector is attached to the first igniter, the first lead wire extends only in a predetermined direction on an imaginary plane substantially perpendicular to a central axis of the housing without bending the first lead wire;
- and
- a second igniter attached to said housing and selectively initiated by the activation signals, said second igniter being adapted to receive a second connector provided at one end of a second lead wire, the second lead wire extending from a side peripheral portion of the second connector such that when the second connector is attached to the second igniter, the second lead wire extends only in the predetermined direction and only on the imaginary plane without bending the second lead wire.
1 more element
A method of connecting lead wires to igniters attached to multistage type air bag gas generator, comprising:
- providing the gas generator with a first igniter;
- providing the gas generator with a second igniter;
- providing a first lead wire having a first connector, provided on a first end thereof, for selectively connecting the first lead wire to the first igniter, the first lead wire extending from a side peripheral portion of the first connecter such that when the first connector is attached to the first igniter, the first lead wire is permitted to extend only in a predetermined direction on an imaginary plane substantially perpendicular to a central axis of a gas generator housing without bending the first lead wire;
- and
- providing a second lead wire having a second connector, provided on a first end thereof, for selectively connecting the second lead wire to the second igniter, the second lead wire extending from a side peripheral portion of the second connecter such that when the second connector is attached to the second igniter, the second lead wire is permitted to extend only in the predetermined direction and only on the imaginary plane without bending the second lead wire.
