The seat back 102 is provided with a first shaft portion 103 on the lower side along the left-right direction, and the seat back 102 is provided with a second shaft portion 104 on the upper side along the left-right direction. The seat back 102 is pivotally supported by the first shaft portion 103 so that the upper side can rotate back and forth, that is, the seat back 102 can be reclined. The second shaft portion 104 is a member for rotatably supporting the movable portion (described later) in the present invention, and will be described later together with a description of the movable portion.

The temperature control device 1 includes a movable portion 2 and a temperature control portion 3. Further, in the present embodiment, a detection unit 4 is provided for driving and stopping the temperature control unit 3. The detection unit 4 will be described later with reference to FIG.

The movable portion 2 is supported by the seat back 102 and can move between the storage position stored in the seat back 102 and the separated position separated forward from the storage position. The movable portion 2 accommodates luggage between the lower portion of the movable portion 2 that has moved forward and the upper portion of the seat cushion 101. The movable portion 2 shown in FIG. 1 is arranged at the storage position.
When the movable portion 2 in the present embodiment is arranged at the storage position shown in FIG. 1, the movable portion 2 is provided so as to be substantially parallel to the seat back 102 on the front side of the seat back 102, and the movable portion 2 rotates forward. It has the second shaft portion 104 that supports the shaft so as to be possible. The movable portion 2 is formed as a part of the seat back 102, and as shown in FIG. 1, the movable portion 2 is a front surface layer portion on the seat back 102 on which the occupant leans on the back surface. The portion of the movable portion 2 that directly hits the back surface of the occupant and forms a plate is referred to as the cover portion 21. The front surface of the cover portion 21 preferably has cushioning properties, breathability, and the like for the comfort of the back surface when the occupant sits on the seat 100.
The second shaft portion 104 that pivotally supports the movable portion 2 is a hinge member that is attached to a part of the seat frame 105 (broken line) that is often built in the existing vehicle-mounted seat. The seat frame 105 usually has an upper and lower portion extending in the vertical direction at both left and right ends of the seat back 102, and a left and right portion connecting the upper ends of the left and right upper and lower portions at the upper end of the seat back 102.

The control and operation of the control unit 31 and the transmission unit 32 will be described later.

FIG. 2 shows a process of rotating the movable portion 2 to prepare for temperature control of the luggage B.
As shown in FIG. 2A, the movable portion 2 is particularly centered on the second shaft portion 104 from the storage position (initial position indicated by the alternate long and short dash line) at which the occupant can lean the back surface of the cover portion 21. By rotating the cover portion 21, the cover portion 21 is separated from the front side upward to the separation position (solid line).
The second shaft portion 104 has a lock mechanism so that the movable portion 2 can be fixed at a predetermined position or an arbitrary position when the cover portion 21 is moved forward and upward by rotating the movable portion 2. Using this locking mechanism, the movable portion 2 is fixed in a state where the cover portion 21 is rotated so as to be substantially horizontal. Further, the cover portion 21 and the seat cushion 101 are substantially parallel to each other.
As shown in FIG. 2A, in the movable portion 2, particularly when the cover portion 21 moves from the storage position (dashed line) to the separated position (solid line), the movable portion 2 is in front of the seat 100 in the upper region of the seat cushion 101, specifically. Will protrude in front of the seat back 102.

When the movable portion 2 is fixed at a separated position, the luggage B can be accommodated between the cover portion 21 of the movable portion 2 and the seat cushion 101 as shown in FIG. 2 (b). In the present invention, the region partitioned by the cover portion 21 on the upper side, the seat cushion 101 on the lower side, and the seat back 102 on the rear side (the region surrounded by the alternate long and short dash line) is the region where the temperature is controlled by the temperature control portion. It is referred to as an adjustment region S. That is, the luggage B is accommodated in the temperature control region S.

It should be noted that the baggage B preferably stored in the temperature control region S is preferably temperature-controlled, and specifically, refrigerated foods, frozen foods, fresh foods, and perishable foods that require a temperature lower than normal temperature. Examples of foods that require a higher temperature than normal temperature include warm foods. Whether cold air or hot air is required may be set manually by the occupant or may be set automatically. As this automatic setting mode, for example, a temperature sensor is attached to any of the temperature control regions S, and if it is detected that the luggage B is lower than the normal temperature, the temperature setting is lowered and the temperature is higher than the normal temperature. If it is detected, it is possible to adopt a form in which the temperature setting is set to a high temperature.

As shown in FIG. 2B, the cover portion 21 in the present embodiment has a hanging lower portion 22 which is a hook-shaped member at a portion facing downward when the cover portion 21 is projected forward from the seat back 102. The hanging lower portion 22 is stored in the cover portion 21 when the movable portion 2 is arranged in the storage position, and can be pulled down and used when the luggage B is suspended.
In the present embodiment, the cover portion 21 is arranged at a separated position, the hanging lower portion 22 is pulled out, and the luggage B is suspended from the hanging lower portion 22, whereby the luggage B is accommodated in the temperature control region S. It should be noted that disposing the cover portion 21 at a separated position and placing the luggage B on the seat cushion 101 without using the hanging lower portion 22 is also included in the accommodation of the luggage B in the temperature control region S.

The detection unit 4 shown in FIG. 1 detects the movement of the movable portion 2, the fixing of the movable portion 2, and the suspension of the luggage B to the hanging lower portion 22. The movement of the movable portion 2 is detected when, for example, a sensor attached to the second shaft portion 104 that can detect the rotation angle detects that the movement exceeds a predetermined rotation angle. And. Further, the fixation of the movable portion 2 can be detected by, for example, a sensor that detects that the lock mechanism attached to the second shaft portion 104 is in the locked state. The detection of suspension of the luggage B to the hanging lower portion 22 is performed by, for example, a weight sensor attached to the hanging lower portion 22 or a torque sensor attached to the second shaft portion 104 to detect the luggage on the second shaft portion 104 in a fixed state. It is assumed that the suspension of the luggage B is detected when it is detected that the load of B is acting.
As shown in FIG. 1, the detection unit 4 can output the detection result to the temperature control unit 3.

When the movable portion 2 is arranged at the storage position, as shown in FIG. 1, the upper region of the seat cushion 101 is not covered by any member, so that the movable portion 2 is in an open state. Therefore, when the movable portion 2 is arranged at the storage position, for example, as in the conventional case, an appropriate load that requires temperature control is placed on the seat cushion 101, and the temperature is controlled by in-vehicle air conditioning. However, the upper part of the luggage is greatly opened, and the temperature control efficiency becomes extremely poor due to sunlight that may shine through the window.

On the other hand, when the movable portion 2 is arranged at a separated position, the upper region of the seat cushion 101 is substantially covered by the cover portion 21 projecting forward from the seat 100, more specifically, the seat back 102. It has become. Therefore, when the temperature of the luggage B accommodated in the temperature control region S is adjusted while the movable portion 2 is arranged at a separated position, the upper portion of the luggage B is substantially closed, and the sunlight shining through the window is the cover portion 21. Because it is shielded from light, the efficiency of temperature control is improved.

By providing the hanging lower portion 22, the luggage B can be held at a position closer to the cover portion 21 of the movable portion 2 as compared with the case where the luggage B is placed on the seat cushion 101. When the luggage B is held at a position close to the cover portion 21, the light-shielding action of the cover portion 21 can be further exerted. Further, when the luggage B is hung from the hanging lower portion 22, it does not come into contact with the seat cushion 101 or the like, or it is difficult for the luggage B to come into contact with the seat cushion 101, so that heat transfer due to the contact is less likely to occur.
By providing the suspension lower portion 22 in this way, the efficiency of temperature control is further improved.

In the present invention, various forms can be adopted as the flow form of air to the temperature control region S in a state where the movable portion 2 is arranged at a separated position. Here, the flow mode of air to the temperature control region S will be described with reference to FIG.
3 (a) to 3 (c) are schematic views showing the flow mode of the temperature-controlled air blown out from the temperature control unit to the temperature control region S. In the description of the embodiment shown in FIG. 3, when the same members as those shown in FIGS. 1 and 2 are used, the same reference numerals are given and detailed description thereof will be omitted.

The embodiment shown in FIG. 3A is the same as the embodiment shown in FIGS. 1 and 2, and specifically shows the flow of air from the temperature control unit 3. As shown in FIG. 3A, the air temperature controlled by the temperature control unit 3 arranged inside the instrument panel 300 (hereinafter referred to as “instrument panel”) is arranged in the foot region of the seat 100. It is blown into the vehicle interior toward the temperature control region S through the air outlet 301. The air blown out from the outlet 301 travels substantially straight to reach the temperature control region S and hits the luggage B.
In the embodiment shown in FIG. 3A, the temperature control unit 3 shares a member (heating, ventilation, air conditioning (HVAC) system, etc.) used for air conditioning of the entire vehicle interior provided inside the instrument panel 300, and the air outlet. The foot air conditioning via 301 is used. The temperature control unit 3 normally controls the temperature for air conditioning in the vehicle, and only when the temperature is blown toward the temperature control region S, the temperature setting is made independent of the air conditioning setting for the entire vehicle interior, so that the property of the luggage B is It is possible to realize an arbitrary set temperature according to the above.

The embodiment shown in FIG. 3 (b) is a modification of the air flow path of the embodiment shown in FIG. 3 (a). As shown in FIG. 3B, the temperature control device 11 is provided with a duct 33. The air whose temperature is controlled by the temperature control unit 3 arranged inside the instrument panel 300 reaches the sheet 100 through a duct 33 which is embedded under the floor unit 200 and extends below the sheet 100. Further, the end of the duct 33 extends to the lower part of the seat cushion 101 and the lower part of the seat back 102. The end of the duct 33 is connected to the seat air conditioning duct 106 embedded inside the seat cushion 101 and the seat back 102. The seat air-conditioning duct 106 is opened at the upper surface of the seat cushion 101 and the front surface of the seat back 102 so that air-conditioned air can flow out from the seat surface and the back surface from the vicinity of the occupant when the occupant sits on the seat 100. It has become. Since the seat air-conditioning duct 106 is open facing the seating area of the occupant, it is also open facing the temperature control area S. Therefore, the air from the temperature control unit 3 that has reached the seat 100 through the duct 33 flows into the temperature control region S through the seat air conditioning duct 106.

In the embodiment shown in FIG. 3B, similarly to the embodiment shown in FIG. 3A, the temperature control unit 3 shares a member (HVAC system or the like) used for air conditioning of the entire vehicle interior. By using the duct 33 and the seat air-conditioning duct 106 that pass under the floor portion 200, it is not necessary to consider the diffusion of the blown air into the vehicle interior, and the temperature is surely controlled in the temperature control region S. Air can be introduced.

In the embodiment shown in FIG. 3C, an independent temperature control unit 30 is arranged on the sheet 100. As shown in FIG. 3C, the temperature control device 12 is arranged on the floor portion 200, and the temperature control portion 30 is provided inside the base member 107 for fixing and arranging the sheet 100. The air whose temperature has been controlled by the temperature control unit 30 flows into the temperature control region S via the seat air-conditioning duct 106, similarly to the temperature control device 11 shown in FIG. 3 (b).
In the embodiment shown in FIG. 3C, the temperature control unit 30 is provided as a separate member independent of the member (HVAC system or the like) used for air conditioning of the entire vehicle interior provided inside the instrument panel 300. Since the temperature control unit 30 is attached to the sheet 100 to send air from a position close to the temperature control area S, air is blown out from the temperature control section 30 until it is introduced into the temperature control area S. Unintended temperature changes are unlikely to occur.

Here, the control when the temperature control device 1 is used will be described with reference to FIG.
Note that FIG. 4 is a flowchart showing a control flow when the temperature control device 1 shown in FIGS. 1, 2 and 3 (a) is used to control the temperature of the temperature control region S in which the luggage B is accommodated. Is.

First, the occupant seated in the driver's seat with the luggage B moves the movable portion 2 of the passenger seat 100 forward (step S1). By this step, the movable portion 2 arranged in the storage position so that the cover portion 21 is substantially parallel to the seat back 102 is rotated around the second shaft portion 104 to the separated position. The cover portion 21 is in a state of protruding forward from the seat back 102. It is preferable to keep the movable portion 2 that has been rotated in a fixed state. When this step is completed, the temperature control region S is formed between the movable portion 2 and the seat cushion 101.
This step is basically performed manually to simplify the seat structure, but if necessary, a rotation switch for the movable portion 2 is provided in the vehicle interior, and an actuator or the like is provided for the second shaft portion 104. It may be automated by this.

Next, the luggage B carried by the occupant is accommodated in the temperature control region S (step S2). In this step, the occupant can put the luggage B in the temperature control region S in substantially the same operation as the operation of placing the luggage B on the adjacent seat cushion 101, so that the operation is completed by a simple operation. The accommodation of the luggage B in the present embodiment is achieved by pulling out the hanging lower portion 22 from the cover portion 21 and suspending the luggage B below the cover portion 21 as described above with reference to FIG. 2 (b). Will be done.
Before and after the storage operation of the luggage B, it is preferable that the control unit 31 sets the temperature of the air blown out toward the temperature control region S by the delivery unit 32 in the temperature control unit 3. The temperature may be set manually by the occupant. A temperature sensor is attached to one of the temperature control areas S, and the temperature is automatically set according to the temperature of the luggage B to maintain the temperature. Is also good.

Further, the control unit 31 of the temperature control unit 3 determines whether or not the movable unit 2 is rotated to the separated position and is in the fixed state (step S3). In this step, when it is determined that the second shaft portion 104 that pivotally supports the movable portion 2 is locked based on the detection result of the detection unit 4, the process proceeds to the next step (YES in step S3). If it is determined that the movable portion 2 is not fixed, this step is repeated until the movable portion 2 is fixed (NO in step S3).
In the present embodiment, the detection unit 4 detects not only whether or not the movable portion 2 is fixed at the separated position, but also the movement of the movable portion 2 to the separated position and the suspension of the luggage B to the hanging lower portion 22. Since it is possible, whether or not the movable portion 2 has moved to a separated position instead of whether or not the movable portion 2 is fixed, or whether or not the movable portion 2 is fixed, and whether or not the luggage B is suspended below 22 It may be determined whether or not it is hung on the ground.

When the movable portion 2 is fixed (YES in step S3), the control unit 31 of the temperature control unit 3 determines whether or not the foot air conditioner installed in front of the seat 100 is being driven (step). S4). In the present embodiment, the temperature control unit 3 used for air conditioning for the entire vehicle interior, that is, for the occupant, is also shared for temperature control of the temperature control area S, so that the foot of the seat 100, that is, the temperature control area is already used. It is necessary to divide the operation mode of the temperature control unit 3 depending on whether or not air conditioning is performed in the vicinity of S.

When the foot air conditioning of the seat 100 by the temperature control unit 3 is driven (YES in step S4), only the foot air conditioning is changed to the setting suitable for the luggage B in the temperature setting of the sending air in the sending unit 32 (step S52). ). The foot air conditioning by the temperature control unit 3 may be maintained to be driven.
If the foot air conditioning of the seat 100 is not driven (NO in step S4), the delivery unit 32 is driven for the luggage B (step S51).
Regardless of the determination result of the previous step (step S4), as a result, as shown in FIG. 3A, the air whose temperature is controlled by the delivery unit 32 is the air outlet provided in the lower part of the instrument panel 300. It flows into the temperature control region S via the 301. Although the movable portion 2 in the present embodiment is in an open state on the side when fixed at a separated position, the temperature control region S is covered with a cover portion 21 on the upper side, a seat back 102 on the rear side, and a seat cushion 101 on the lower side. Therefore, the cold air or warm air that has flowed into the temperature control region S tends to stay in the temperature control region S. As a result, the luggage B is maintained at a temperature lower or higher than the normal temperature, which is the temperature intended by the occupant.
In order to reduce the lateral gap in the temperature control region S, for example, it is preferable to adopt a form in which a curtain-shaped or shade-shaped expandable closing member is provided on the side of the center side of the vehicle.

In the present embodiment, the temperature control of the temperature control region S by the temperature control unit 3 is performed independently of the air conditioning of the entire vehicle interior for the occupant, in particular, the temperature setting of the delivery air of the delivery unit 32 is performed. Normally, the air conditioning of the entire vehicle interior is around 25 ° C for cooling and around 30 ° C for heating, but for example, for refrigerated foods and frozen foods, it is 15 ° C or less, and for warm lunch boxes, etc. The temperature is preferably 35 ° C. or higher. By making the setting and control related to the temperature control independent for the entire vehicle interior and the temperature control area S, appropriate air conditioning for both the occupant and the luggage B becomes possible.
