A seat heater mounted to a seat includes: a heating wire; a base material provided with the heating wire and having air permeability; an excessive temperature rise prevention element that prevents an excessive temperature rise of the heating wire; and an auxiliary heating wire that heats the excessive temperature rise prevention element, in which air permeability in an auxiliary heater area provided with the auxiliary heating wire is lower than air permeability in a heater area provided with the heating wire, so that heat dissipation in the auxiliary heater area is suppressed to enable a temperature of the excessive temperature rise prevention element to rise efficiently to follow the temperature rise of the heater area.

A steering wheel heater includes: a base material that is wound around a steering wheel; a heater wire that generates heat by an electric current flowing through the heater wire; and a sewing thread that is used to sew the heater wire to one surface of the base material. A plurality of through holes that have a diameter smaller than a sewing pitch of stitches of the sewing thread used to sew the heater wire are formed in the base material.

A vehicle seat heater is provided in a vehicle seat. This vehicle seat heater includes a first heat generator, second heat generator, and controller. The first heat generator is disposed in a first area of the vehicle seat supporting an occupant. The second heat generator is disposed in a second area not being in contact with the occupant or being less pressed by the occupant than the first area is. The controller controls current application to the first heat generator in a manner such that a heating temperature zone of the first heat generator is a direct heat transfer temperature zone close to a body temperature of the occupant, and also controls current application to the second heat generator in a manner such that a heating temperature zone of the second heat generator is a radiation heat transfer temperature zone.

A seat heater includes a seating heater, a protection device of a non-resettable type, a base material, and a protecting heater. The protection device has a first surface and a second surface opposite to the first surface. The base material is a sheet having a first covering portion covering the first surface and a second covering portion covering the second surface, and is folded so that the first covering portion and the second covering portion face each other. The protecting heater heats the protection device. The protecting heater includes a pair of first heating portions and a second heating portion. The pair of first heating portions are formed as a meandered shape only on a surface, which faces the second covering portion, of the first covering portion. The second heating portion is disposed between the pair of first heating portions, and formed as a meandered shape both on the surface, which faces the second covering portion, of the first covering portion, and on a surface, which faces the first covering portion, of the second covering portion.

A seat heater that is a seat including: a planer heating element that has a plurality of electric heating wires on its upper surface and that includes a fiber layer; a cushion member that locates over a lower surface of the planer heating element; and a skin that locates above the planer heating element, wherein the planer heating element has, in voids of the fiber layer, a silica aerogel that is a silica porous body having pores with a mean pore diameter of 10 nm to 68 nm.

An in-vehicle heating device according to the present invention is provided on a lower part of a front side of a seat cushion () serving as a seating unit of a vehicle seat (). The in-vehicle heating device includes: an air feeder () including a suction opening () through which external air is sucked into the air feeder (); a warm air generator () including a heater () therein, the warm air generator () being configured to heat air fed from the air feeder () to generate warm air; and a blow-out unit configured to blow out the warm air from the warm air generator (), such that the warm air is blown out forward of the seat cushion (). At least a part of the blow-out unit is positioned at a front of the seat cushion (), and doubles as a front shield, which serves as a decorative member.

A temperature detection unit detects the temperature of a power plug. A control unit stops electric conduction to a battery when the detected temperature detected by the temperature detection unit is equal to or higher than a predetermined specified temperature (T). The control unit recovers the electric conduction to the battery when the detected temperature detected by the temperature detection unit decreases to a specified temperature (T) or lower, the specified temperature (T) being lower than the specified temperature (T).

Charging cable

A seat heater includes: a base material; and a heater wire disposed on the base material. The base material has a fold-back portion projecting from an edge of the base material where a cutout portion is formed. The heater wire is disposed on the fold-back portion. In a state where the fold-back portion is folded back toward a base material side, a proximal portion of the fold-back portion is positioned inside the edge of the base material. With such a configuration, the seat heater whose temperature elevation performance is not deteriorated can be realized.

A charging cable for use in charging a battery of an electrically-driven vehicle includes a power plug to be detachably connected to a receptacle outlet of a commercially available power source, a charging coupler to be detachably connected to the electrically-driven vehicle, a temperature sensor for detecting a temperature of an electric circuit between the power plug and the charging coupler, and a charging device having a controller for controlling a current value that flows from the power plug to the charging coupler. This configuration can minimize the charging time and enhance the durability between the charging cable and the receptacle outlet and between the charging cable and the charging coupler.
