Abstract
A steering wheel heater device including: a heating wire; a power line connected in series to the heating wire, for supplying the heating wire with power; a ground line connected in series to the heating wire; a lead-out wire connected to a point along a wiring pattern formed of the heating wire; and a contact detection circuit electrically connected to the wiring pattern formed of the heating wire through the lead-out wire, wherein a portion of the wiring pattern is connected in series between the ground line and the contact detection circuit.
Claims27
A steering wheel heater device comprising:
- a heating wire having a first end connected to a power line and a second end connected to a ground line;
- a lead-out wire connected to a point along a wiring pattern formed of the heating wire;
- and
- a contact detection circuit electrically connected to the wiring pattern through the lead-out wire, wherein
- a portion of the wiring pattern formed of the heating wire and the lead-out wire are connected in series between the ground line and the contact detection circuit.
A steering wheel heater comprising:
- a heating wire;
- a first connecting member connected to a first end of the heating wire, the first connecting member being externally connected;
- a second connecting member connected to a second end of the heating wire, the second connecting member being externally connected;
- a lead-out wire connected to a portion between the first end and the second end which is a point along a wiring pattern formed of the heating wire;
- and
- a third connecting member connected to the lead-out wire, the third connecting member being externally connected, wherein
- the first connecting member or the second connecting member is connected to an external power line through which a direct-current passes, the third connecting member being connected to an external signal line.
A steering wheel comprising:
- a first heating wire having a first end connected to a power line and a second end connected to a ground line;
- a second heating wire having a first end connected to the power line and a second end connected to the ground line;
- a first lead-out wire connected to a point along a first wiring pattern formed of the first heating wire;
- a second lead-out wire connected to a point along a second wiring pattern formed of the second heating wire;
- a first contact detection circuit electrically connected to the first wiring pattern through the first lead-out wire;
- and
- a second contact detection circuit electrically connected to the second wiring pattern through the second lead-out wire, wherein
- a portion of the first wiring pattern formed of the first heating wire and the first lead-out wire are in series between the ground line and the first contact detection circuit,
- a portion of the second wiring pattern formed of the second heating wire and the second lead-out wire are connected in series between the ground line and the second contact detection circuit, and
- the first wiring pattern formed of the first heating wire and the second wiring pattern formed of the second heating wire are included on left and right, respectively, of the steering wheel.
A steering wheel comprising:
- a heating wire having a first end connected to a power line and a second end connected to a ground line;
- a lead-out wire connected between a first wiring pattern and a second wiring pattern which are formed of the heating wire;
- and
- a contact detection circuit electrically connected to the wiring pattern through the lead-out wire, wherein
- the first wiring pattern or the second wiring pattern formed of the heating wire and the lead-out wire are connected in series between the ground line and the contact detection circuit, and
- the first wiring pattern and the second wiring pattern are included on right and left, respectively, of the steering wheel.
