Japanese Utility Model Publication No. 4-7937

  However, the conventional armrest for a vehicle does not include a heater in the door trim. Therefore, when the occupant places the forearm on the upper surface of the armrest, there is a problem that the occupant feels a temperature difference between the portion that contacts the door trim and the portion that contacts the armrest.

  This indication is made paying attention to the above-mentioned problem, and it aims at providing the armrest for vehicles which can reduce the temperature difference which a crew member feels with an armrest and a door trim.

  In order to achieve the above object, an armrest for a vehicle according to the present disclosure includes an armrest heater that warms an upper surface region that supports a forearm of a seated occupant. The door trim installed on the door of the vehicle includes a door trim heater that warms a contact area where the door trim and the forearm contact. In this vehicle armrest, when the region heated by the door trim heater is the first region and the region heated by the armrest heater is the second region, the heat generation amount of the first region is set larger than the heat generation amount of the second region.

  As described above, by setting the heat generation amount in the first region to be larger than the heat generation amount in the second region, it is possible to reduce the temperature difference felt by the occupant between the armrest and the door trim.

[Heater configuration]
FIG. 5 is a configuration diagram illustrating a configuration of the door trim heater according to the first embodiment. FIG. 6 is a configuration diagram illustrating the configuration of the armrest heater according to the first embodiment. Hereinafter, the configuration of the door trim heater and the armrest heater will be described with reference to FIGS. 1, 2, 5, and 6. In addition, the shape of the door trim heater 33 and the armrest heater 14 is simplified and described for convenience of explanation.

  As shown in FIGS. 1 and 2, the door trim heater 33 is disposed on the outer side in the vehicle width direction than the armrest heater 14. The door trim heater 33 and the armrest heater 14 have substantially the same length in the vehicle front-rear direction.

  The armrest heater 14 is provided below the upper surface area of the arm restorer 11. The armrest heater 14 is provided over the entire upper surface area of the arm restorer 11. That is, the armrest heater 14 warms the position in contact with the forearm supported by the upper surface region of the arm restorer 11 from below. The upper surface area where the armrest heater 14 is heated is defined as a second area S2.

  The door trim heater 33 is provided on the wall portion of the door center 30. The door trim heater 33 warms the contact area where the forearm supported by the upper surface area of the arm restorer 11 contacts the door center 30 as the door trim 1 from the side. A contact area where the door trim heater 33 is heated is defined as a first area S1.

  As shown in FIG. 5, the heating wire 35 of the door trim heater 33 is formed of a nichrome wire or the like, and is arranged meandering in the vehicle front-rear direction. The heating wires 16 of the door trim heater 33 are arranged at the arrangement pitch H1 over the entire position corresponding to the first region S1.

  As shown in FIG. 6, the heating wire 16 of the armrest heater 14 is formed of a nichrome wire or the like, and is arranged meandering in the vehicle front-rear direction. The heating wire 16 is formed of the same material and the same diameter as the heating wire 35. The heating wire 16 of the armrest heater 14 is arranged at an arrangement pitch H2 larger than the arrangement pitch H1 over the entire position corresponding to the second region S2. That is, the wiring density of the heating wire 35 in the first region S1 is higher than the wiring density of the heating wire 16 in the second region S2. Therefore, the heat generation amount of the first region S1 is larger than the heat generation amount of the second region S2.

[Control structure of heater]
FIG. 7 is a block diagram illustrating the control configuration of the heater according to the first embodiment. The heater control configuration will be described below with reference to FIG.

  The heater switch 19 a and the temperature sensor 70 are connected to the input port of the control unit 60. The armrest heater 14 and the door trim heater 33 are connected to the output port of the control unit 60.

  An input signal from the heater switch 19a is transmitted to the control unit 60. An input signal from the temperature sensor 70 is transmitted to the control unit 60.

  The control unit 60 receives input signals from the heater switch 19 a and the temperature sensor 70 and transmits one output signal to the armrest heater 14 and the door trim heater 33. That is, the control unit 60 stops driving the armrest heater 14 and the door trim heater 33 based on the same control signal, and controls the temperature of the first region S1 and the temperature of the second region S2.

[Heater control processing configuration]
FIG. 8 is a flowchart illustrating the flow of the heater control process according to the first embodiment. Hereinafter, each step of the heater control processing configuration executed by the control unit 60 will be described with reference to FIG.

  In step S1, the control unit 60 determines whether or not the heater switch 19a is ON. If it is determined that the heater switch 19a is ON (YES), the process proceeds to step S2. On the other hand, if it is determined that the heater switch 19a is not ON (NO), the determination in step S1 is repeated.

  In step S2, following the determination that the heater switch 19a is ON in step S1, the control unit 60 turns on the armrest heater 14 and the door trim heater 33, and proceeds to step S3.

  In step S3, following the ON of the armrest heater 14 and the door trim heater 33 in step S2, the control unit 60 determines whether or not the temperature detected by the temperature sensor 70 is higher than the heater OFF threshold. When it is determined that the temperature detected by the temperature sensor 70 is higher than the heater OFF threshold (YES), the process proceeds to step S4. On the other hand, if it is determined that the temperature detected by the temperature sensor 70 is lower than the heater OFF threshold (NO), the determination in step S3 is repeated. Here, the heater OFF threshold is set to 37 ° C., for example.

  In step S4, following the determination that the temperature detected by the temperature sensor 70 in step S3 is higher than the heater OFF threshold, the control unit 60 turns off the armrest heater 14 and the door trim heater 33, and proceeds to step S5.

  In step S5, following the turning off of the armrest heater 14 and the door trim heater 33 in step S4, the control unit 60 determines whether or not the temperature detected by the temperature sensor 70 is lower than the heater ON threshold. When it is determined that the temperature detected by the temperature sensor 70 is lower than the heater ON threshold (YES), the process proceeds to step S6. On the other hand, if it is determined that the temperature detected by the temperature sensor 70 is higher than the heater ON threshold (NO), the determination in step S5 is repeated. Here, the heater ON threshold is set to 36 ° C., for example.

  In step S6, following the determination that the temperature detected by the temperature sensor 70 in step S5 is lower than the heater ON threshold, the control unit 60 turns on the armrest heater 14 and the door trim heater 33, and proceeds to step S7.

  In step S7, following the ON of the armrest heater 14 and the door trim heater 33 in step S6, the control unit 60 determines whether or not the heater switch 19a is OFF. When it is determined that the heater switch 19a is OFF (YES), the process proceeds to step S8. On the other hand, if it is determined that the heater switch 19a is not OFF (NO), the process returns to step S3.

  In step S8, following the determination that the heater switch 19a is OFF in step S7, the control unit 60 turns off the armrest heater 14 and the door trim heater 33, and proceeds to the end.

Next, the operation will be described.
The operation of the vehicle armrest according to the first embodiment will be described by dividing it into “comparison operation” and “heater control processing operation”.

[Comparison effect]
As shown in FIG. 2, the door trim 1 is generally disposed outside the armrest 10 in the vehicle width direction. Therefore, when the door trim 1 and the armrest 10 are provided with heaters, the door trim heater 33 is disposed outside the armrest heater 14 in the vehicle width direction. Further, a molded urethane as the second cushion layer 17 is disposed between the armrest heater 14 and the core material 18, while a molded urethane is disposed between the door trim heater 33 and the core material 36. It has not been. Therefore, the heat loss from the door trim 1 is larger than the heat loss from the armrest 10.

  Here, for example, the arrangement pitch of the heating wire of the armrest heater and the arrangement pitch of the heating wire of the door trim heater are the same as the comparative example.

  In the case of the comparative example, as shown in FIG. 9, the amount of heat generated from the armrest heater and the amount of heat generated from the door trim heater are the same.

  Then, as described above, since the heat loss from the door trim is larger than the heat loss from the armrest, as shown in FIG. 10, on the surface of the arm restorer as the armrest and the surface of the door center as the door trim, There is a problem that a temperature difference occurs.

  In contrast, in the first embodiment, the armrest 10 that supports the forearm of the seated occupant includes the armrest heater 14 that warms the upper surface region that supports the forearm of the seated occupant. The door trim 1 installed in the door body 4 of the vehicle includes a door trim heater 33 that warms a contact area where the door trim 1 and the forearm contact. In this armrest 10, when the region heated by the door trim heater 33 is the first region S1, and the region heated by the armrest heater 14 is the second region S2, the amount of heat generated in the first region S1 is the amount of heat generated in the second region S2. A larger value is set (FIGS. 5 and 6).

  That is, heat loss from the door trim 1 can be compensated. For this reason, the temperature of the first region S1 is approximated to the temperature of the second region S2.

  Specifically, in the case of the first embodiment, as shown in FIG. 11, the heat generation amount from the door trim heater 33 is larger than the heat generation amount from the armrest heater 14.

  Therefore, as shown in FIG. 12, the temperature of the second region S2 can be approximated to the temperature of the first region S1.

  By the way, if the main battery is used for power supply to the armrest heater and the door trim heater, normal power cannot be supplied when idling is stopped. Therefore, there is a problem that it is impossible to stably ensure the comfort of the passenger.

  Therefore, a sub-battery is used to supply power to the armrest heater and the door trim heater. The sub-battery stores regenerative energy during braking and supplies electric power. The sub battery performs power supply when normal power supply by the main battery is not possible. Thereby, a passenger | crew's comfort can be ensured stably.

  However, the upper limit of the voltage value is determined for the sub-battery. Therefore, it is not preferable to control the heat generation amount of the armrest heater and the door trim heater by the current value.

  On the other hand, in Example 1, the wiring density of the heating wire in the first region S1 is set higher than the wiring density in the second region S2 (FIGS. 5 and 6).

  That is, the current supplied to the door trim heater 33 and the armrest heater 14 can be made the same, and the heat generation amount of the door trim heater 33 can be made larger than the heat generation amount of the armrest heater 14.

  Moreover, the heating wire 35 of the door trim heater 33 and the heating wire 16 of the armrest heater 14 can be formed with the same material and the same diameter. For this reason, the temperature of the first region S1 is approximated to the temperature of the second region S2 with a simple configuration.

[Controlling action of heater]
The heater control processing operation executed by the control unit 60 of the first embodiment will be described with reference to FIG.

  First, if the heater switch 19a is ON, the process proceeds from step S1 to step S2 to step S3 in the flowchart shown in FIG. That is, when the heater switch 19a is ON, the armrest heater 14 and the door trim heater 33 are turned ON, and the temperature of the arm restorer 11 as the armrest 10 and the door center 30 as the door trim 1 is increased.

  In step S3, it is determined whether or not the temperature detected by the temperature sensor 70 is higher than 37 ° C. as the heater OFF threshold. If it is determined in step S3 that the temperature detected by the temperature sensor 70 is higher than 37 ° C. as the heater OFF threshold, the process proceeds from step S4 to step S5. That is, when the surface temperature of the armrest 10 exceeds 37 ° C., the armrest heater 14 and the door trim heater 33 are turned off.

  In step S5, it is determined whether or not the temperature detected by the temperature sensor 70 is lower than 36 ° C. as the heater ON threshold. If it is determined in step S5 that the temperature detected by the temperature sensor 70 is lower than 36 ° C. as the heater ON threshold, the process proceeds from step S6 to step S7. That is, when the surface temperature of the armrest 10 falls below 36 ° C., the armrest heater 14 and the door trim heater 33 are turned on.

  In step S7, it is determined whether or not the heater switch 19a is OFF. Thereafter, when it is determined in step S7 that the heater switch 19a is OFF, the process proceeds from step S8 to end. On the other hand, if it is determined that the heater switch 19a is ON, the process returns to step S3. That is, when the heater switch 19a is OFF, the armrest heater 14 and the door trim heater 33 are turned OFF to end. On the other hand, if the heater switch 19a is ON, the process returns to step S3.

  The heater control processing operation executed by the control unit 60 of the first embodiment will be described based on the graph of FIG.

  In FIG. 13, time t1 and time t3 are times when the armrest heater 14 and the door trim heater 33 are turned off. Time t2 and time t4 are times when the armrest heater 14 and the door trim heater 33 are turned on.

  When the heater switch 19a is turned on by an occupant's operation, the armrest heater 14 and the door trim heater 33 are turned on.

  When the surface temperature of the arm restorer 11 as the armrest 10 reaches 37 ° C. at time t1, the armrest heater 14 and the door trim heater 33 are turned off.

  When the surface temperature of the arm restorer 11 as the armrest 10 reaches 36 ° C. at time t2, the armrest heater 14 and the door trim heater 33 are turned on.

  When the surface temperature of the arm restorer 11 as the armrest 10 reaches 37 ° C. at time t3, the armrest heater 14 and the door trim heater 33 are turned off.

  When the surface temperature of the arm restorer 11 as the armrest 10 reaches 36 ° C. at time t4, the armrest heater 14 and the door trim heater 33 are turned on.

  Thus, by repeating ON / OFF of the armrest heater 14 and the door trim heater 33, the temperature of the first region S1 and the temperature of the second region S2 can be brought close to the target temperature.

  For example, when the drive stop of the door trim heater and the drive stop of the armrest heater are controlled by independent drive signals, there is a problem that the control becomes complicated.

  In contrast, the first embodiment includes a control unit 60 that controls the temperature of the first region S1 and the temperature of the second region S2. The control unit 60 uses the same control signal to control the temperature of the first region S1 and the second region S1. The temperature of the two regions S2 is controlled (FIG. 13).

  That is, the control unit 60 stops driving the armrest heater 14 and the door trim heater 33 based on the same control signal, and controls the temperature of the first region S1 and the temperature of the second region S2. For this reason, the temperature of the first region S1 can be approximated to the temperature of the second region S2 with a simple control configuration.

  The first embodiment includes a control unit 60 that controls the temperature of the first region S1 and the temperature of the second region S2, and the control unit 60 is a temperature sensor provided in either the first region S1 or the second region S2. Based on the detected temperature of 70, the temperatures of the first region S1 and the second region S2 are controlled (FIG. 13).

  That is, when the temperature of the first region S1 is approximated to the temperature of the second region S2, the temperature of the first region S1 and the temperature of the second region S2 are controlled based on the temperature detected by one temperature sensor 70. . For this reason, the temperature of the first region S1 and the temperature of the second region S2 can be controlled with a simple configuration.

Next, the effect will be described.
In the vehicle armrest in the first embodiment, the following effects can be obtained.

(1) The armrest 10 that supports the forearm of the seated occupant includes an armrest heater 14 that warms the upper surface region that supports the forearm of the seated occupant. A door trim 1 installed on a vehicle door (door body 4) includes a door trim heater 33 that warms a contact area where the door trim 1 and a forearm are in contact with each other. In this vehicle armrest (armrest 10), when the region heated by the door trim heater 33 is the first region S1, and the region heated by the armrest heater 14 is the second region S2, the amount of heat generated in the first region S1 is second. It is set larger than the amount of heat generated in the region S2 (FIGS. 5 and 6).
Therefore, the temperature of the first region S1 can be approximated to the temperature of the second region S2.

(2) The wiring density of the heating wire in the first region S1 is set higher than the wiring density in the second region S2 (FIGS. 5 and 6).
Therefore, the temperature of the first region S1 can be approximated to the temperature of the second region S2 with a simple configuration.

(3) A control unit 60 that controls the temperature of the first region S1 and the temperature of the second region S2 is provided, and the control unit 60 sets the temperature of the first region S1 and the temperature of the second region S2 with the same control signal. Control (FIG. 13).
Therefore, the temperature of the first region S1 can be approximated to the temperature of the second region S2 with a simple control configuration.

(4) A control unit 60 that controls the temperature of the first region S1 and the temperature of the second region S2 is provided, and the control unit 60 is a temperature sensor (temperature) provided in either the first region S1 or the second region S2. Based on the detected temperature of the sensor 70), the temperature of the first region S1 and the second region S2 is controlled (FIG. 13).
Therefore, the surface temperature of the door trim 1 and the surface temperature of the armrest 10 can be controlled with a simple configuration.

  The vehicle armrest of the present disclosure has been described based on the first embodiment. However, the specific configuration is not limited to the first embodiment, and design changes and additions are permitted without departing from the gist of the invention according to each claim of the claims.

  In the first embodiment, an example in which the heater switch 19a is provided in the switch operation unit 19 of the armrest 10 is shown. However, the heater switch may be an example provided on the instrument panel.

  In Example 1, the control part 60 showed the example which controls ON / OFF of the armrest heater 14 and the door trim heater 33 with the input signal from the heater switch 19a. However, the present invention is not limited to this mode. For example, the control unit may control ON / OFF of the armrest heater and the door trim heater by an input signal from an air conditioner switch.

  In the first embodiment, an example is illustrated in which the temperature sensor 70 is the temperature sensor 70 that detects the temperature of the second region S2. However, the temperature sensor may be an example of a temperature sensor that detects the temperature of the first region S1.

  Moreover, as an example of a temperature sensor, a temperature sensor that detects the temperature of the first region S1 and a temperature sensor that detects the temperature of the second region S2 may be provided. In this case, when one of the temperature sensors fails, the temperature of the first region and the temperature of the second region can be controlled based on the detected temperature of the other temperature sensor. Therefore, safety can be improved.

  In Example 1, the heating wire 35 of the door trim heater 33 and the heating wire 16 of the armrest heater 14 are shown meandering in the vehicle front-rear direction. However, the heat insulating wire of the door trim heater may be an example of meandering in the vehicle vertical direction, and the heating wire of the armrest heater may be an example of meandering in the vehicle width direction. .

  In Example 1, the example which changes the wiring density of the heating wires 16 and 35 with the arrangement pitch of the heating wires 16 and 35 was shown. However, the arrangement density of the heating wires may be changed depending on the number of heating wires.

  In the first embodiment, an example in which the armrest 10 is constituted by the arm restorer 11 and the armrest lower 42 has been described. However, the armrest may be an example in which an arm restorer and an armrest lower are configured integrally.

  In the first embodiment, the control unit 60 receives an input signal from the temperature sensor 70 and controls ON / OFF of the armrest heater 14 and the door trim heater 33. However, as shown in FIG. 14, the control may be an example in which the PID control is performed so that the surface temperature of the door trim and the surface temperature of the armrest are close to the target values.

  In Example 1, the example which applies the armrest for vehicles to the door trim attached to the front door of a motor vehicle was shown. However, the vehicle armrest may be applied to a door trim attached to a rear door of an automobile. In short, any vehicle armrest provided with an armrest and provided with an armrest heater and a door trim heater can be applied to vehicles other than automobiles.
