Seat for car {Seat for car}

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an automotive seat, and more particularly, to a seat for an automobile which is connected to a front seat of an automobile and to which a cold air and a hot air are supplied, In addition, when a rear seat occupant reads a book or looks for an object, the angle of the lamp can be controlled by the rear seat seated person without disturbing the driver's view due to lighting of the lamp The present invention relates to an automotive seat which can be easily adjusted by an angle.

Generally, a cold air or a warm air supplied from a conventional automobile is supplied only from the front or bottom of the front seat. Such a cold air or hot air supply causes cold air or hot air directly to a seated person sitting on the rear seat behind the front seat It takes a long time for cold air or hot air supplied from the front of the front seat to be supplied to the rear seat, and the seated person of the rear seat has been cold or hot for a long time.

Generally, in order to perform a behavior such as reading a book or searching for a thing on a rear seat at night in a conventional automobile, a lamp in the ceiling of a vehicle is lit to read a book or search for an article Respectively.

However, when a seat occupant sitting on the rear seat lights up a lamp on the ceiling of the vehicle as described above, when the driver reads a book or looks for an object, the light of the lamp is irradiated to the driver, There is a problem that the risk of accidents increases because the eyes are disturbed and the risk of accidents increases and the light of the lamp is not able to quickly grasp information of the vehicle running in the rear.

In order to solve the problems of the conventional art as described above, a suction duct communicating with a suction port formed on an outer circumferential surface of a console box installed in a middle portion of an all-around seat and a temperature control chamber formed inside the console box to communicate with the suction duct A heat exchange core installed inside the temperature control room to be in contact with the air blown from the blowing fan and performing heat and air cooling and heating of the air blown by the thermoelectric operation, And an air duct connected to a discharge port formed on a rear surface of the console box so as to discharge the air that has been communicated, cooled, and heated to the back side, wherein the heat exchange core has one side accommodated in the temperature adjusting chamber, And is accommodated in an exhaust duct which is connected to the outside and separated from the temperature control room, and a plurality of heat dissipation A plurality of thermoelectric elements having one side contacting the outer circumferential surface of one side of the heat pipe, a heat exchange pin contacting the other side of the thermoelectric element, and a plurality of thermoelectric elements mounted between the heat pipe and the heat radiating fin, And a heat insulating material surrounding the lamp, as disclosed in Korean Patent Publication No. 10-1263554, and in a reading device for a passenger car installed in a front seat, a lamp in which a lamp is inserted can be bent in various angles A technique characterized in that the front sheet is fixed to the front sheet through an articulated tube as disclosed in Japanese Patent Application Laid-Open No. 10-1997-0037760.

However, the above-mentioned technology has a structure in which cold air or warm air is supplied only to the console box. In this case, there is a problem that cold air or warm air is supplied only to the legs of the rear seat occupant. In addition, the body of the rear seat occupant is exposed to the outside, There is a problem in that cold or warm air is not supplied to the neck or the face where the body temperature can be lowered or increased most rapidly.

In addition, the above-described technique has a problem that a seat occupant of a rear seat during a car accident is seriously injured by the articulated pipe, and is not visually beautiful.

Accordingly, there is a demand for an automotive seat that solves the above-described conventional problems.

Patent Registration No. 10-1263554 Japanese Patent Application Laid-Open No. 10-1997-0037760
