Abstract

The present invention relates to an automobile seat and a backrest which are mounted inside the seat and the back of the vehicle to warm the seat and the back of the vehicle by using a heating wire connected to the DC power supply of the vehicle. The present invention relates to an automobile seat and a backrest having a large temperature controlled by repetitive operation and a defect in which a deviation of the seat and backrest temperature is greatly generated.

The seat and back of the vehicle whose temperature is controlled by the physical device 100 (bimetal, actuator, thermostat, etc.) using the existing heating wire are set differently according to the type of the physical device 100. According to the discrete ON and OFF 110 is made, as a result of the wide time interval between ON and OFF, there was a large unreasonable point of temperature deviation of the seat and back of the vehicle.

In addition, there are heating mats for vehicle seats using heating wires (Korean practical 93-8616), but this is simply used by connecting heating wires to the cord wires, and there is no thermostat and safety device, resulting in continuous heat generation as well as overheating. There was a problem of fire by.

In addition, in order to solve the above temperature control problem, there is a vehicle auxiliary mat that can control the temperature (Korean practical use 1998-014451), but this is because the skin surrounding the oil is continuously exposed to the temperature by using the oil, not the heating wire, the outer skin In addition to the problem of rupture, the seat and the backrest are connected or integrated by a string, the irrational point and temperature control means of breaking the appendix space containing oil by the weight of the human body physical device 100 (actuator, etc.) By using), the ON-OFF is not continuously performed, and the ON-OFF 110 is made discretely, so that the temperature deviation of the seat and the back of the vehicle is largely unreasonable.

In addition, there is a seat and a backrest for automobiles with a heater applied by the present applicant (Korean-used 99-28073), but this part is made by separating the seat and the backrest separately by using a heating wire, a temperature control device, and a safety device. In addition to the effect of disconnection and the prevention of breakage due to the body's weight, safety devices have been used to improve the risk of fire due to breakdown and overheating, but this is also achieved through the use of a physical device (100) (thermostat, etc.). As a result, the ON-OFF 110 is not made discretely, and the temperature difference between the seat and the back of the vehicle is largely unreasonable.

In order to solve this problem, the present invention further comprises NTC 11, variable resistance multi-stage regulator 40, and ECU 30 to prevent discrete ON-OFF by physical devices. This is to solve the problem that the temperature deviation of the seat and back of the vehicle is large by making the ON-OFF 41 continuously.

The present invention relates to a vehicle seat and a backrest for warming the seat and the back of the vehicle by using a heating wire 15 mounted inside the seat and the back of the vehicle and connected to a DC power source of the vehicle. The present invention relates to an automobile seat and a backrest which have been improved in defects in which a large temperature is controlled by repeated operation of -OFF and a large deviation of the seat and backrest temperature is generated.

The seat and back of the vehicle whose temperature is controlled by the physical device 100 (bimetal, actuator, thermostat, etc.) using the existing heating wire are set differently according to the type of the physical device 100. According to the discrete ON and OFF 110 is made, as a result of the wide time interval between ON and OFF, there was a large unreasonable point of temperature deviation of the seat and back of the vehicle.

In addition, there are heating mats for vehicle seats using heating wires (Korean practical 93-8616), but this is simply used by connecting heating wires to the cord wires, and there is no thermostat and safety device, resulting in continuous heat generation as well as overheating. There was a problem of fire by.

In addition, in order to solve the above temperature control problem, there is a vehicle auxiliary mat that can control the temperature (Korean practical 1998-01451), but this is because the skin surrounding the oil is continuously exposed to the temperature by using the oil, not the heating wire, the outer skin In addition to the problem of rupture, the seat and the backrest are connected or integrated by a string, the irrational point and temperature control means that the oil-filled space is broken by the weight of the human body physical device 100 (actuator, etc.) By using the continuous ON-OFF is not possible, discrete ON-OFF 110 is made, there was a large unreasonable point of temperature deviation of the seat and back of the vehicle.

In addition, there is a seat and a backrest for automobiles with a heater applied by the present applicant (Korean-used 99-28073), but this part is made by separating the seat and the backrest separately by using a heating wire, a temperature control device, and a safety device. In addition to the effect of disconnection and the prevention of breakage due to the body's weight, safety devices have been used to improve the risk of fire due to breakdown and overheating, but this is also achieved through the use of a physical device (100) (thermostat, etc.). As a result, the ON-OFF 110 is not made discretely, and the temperature difference between the seat and the back of the vehicle is largely unreasonable.

The present invention has been made in order to solve the above problems, NTC (11) and the application filed by the present applicant (Korean Utility 99-28073) to prevent discrete ON-OFF by a physical device The variable resistance multi-stage regulator 40, ECU 30 is further configured to solve the problem that the existing temperature deviation is large by the ON-OFF 41 is made continuously by each resistance value.

In order to achieve the above object, the present invention connects the NTC 11 to the heating wire 15 inside the seat, and connects the ECU 30 and the variable resistance multi-stage regulator 40 outside the seat, When the resistance value and the variable resistance value of the variable resistance multi-stage regulator 40 coincide with each other, the signal is turned OFF. When the resistance value of the NTC 11 and the variable resistance value of the variable resistance multi-stage regulator 40 are inconsistent, the value is turned ON. The continuous ON-OFF 41 is made to solve the large irrationality of the existing problem, the temperature deviation of the seat and the back of the vehicle is to improve the system reliability.

When described in detail according to the accompanying drawings to achieve the above object is as follows.

Figure 1 is a circuit diagram according to the present invention, Figure 2 is a perspective view of a seat heater cushion according to the present invention, Figure 3 is a perspective view of a seat heater back according to the present invention, Figure 4 is a seat heater cushion and back according to the present invention 5 is a graph showing a temperature characteristic according to the present invention, FIG. 6 is a temperature characteristic graph using a conventional physical apparatus, and FIG. 7 is a circuit diagram using a conventional physical apparatus.
