发明内容
发明要解决的课题
在专利文献1所记载的电极装置中，为了抑制用于车辆用座椅等的情况下的触感的不协调、闷热感，而由具备伸缩性和通气性的纺织物、编织物构成了电极和绝缘体。
然而，在由纺织物、编织物构成绝缘体的情况下，当在一部分纤维发生绽裂时，绽裂的范围容易向周围扩大。在绽裂的地方绝缘性降低，因此在检测性能上有可能发生不良状况。
于是，在本公开的一方面，目的在于提供确保通气性和柔软性、并且能够抑制相对于电极的绝缘性的降低的传感器装置及其制造方法、以及使用了那样的传感器装置的车辆用座椅。
用于解决课题的方案
根据本公开的一方面，提供具有构成电极的导电性布帛、以及绝缘性的无纺布的传感器装置。所述导电性布帛通过热粘接以及缝合的至少一方而结合与所述无纺布的一个面。
发明效果

具体实施方式
以下，参照附图对本发明的实施方式进行说明。
图1是示出具备本发明的实施方式的传感器装置2的车辆用座椅1的一例的图。在图1的例子中，车辆用座椅1具备靠背部1A和座部1B，在比各自的表面靠内侧处配置有多个传感器装置2。车辆用座椅1例如也可以具备从靠背部1A、座部1B的表面吹送温度调节用的空气的功能。在该情况下，本实施方式的传感器装置2具有通气性，因此不阻碍空气的流动。因此，能够不对温度调节功能带来影响而使传感器装置2配置于靠背部1A、座部1B的适当的部位，能够以良好的灵敏度检测生物体的信息(身体的动作的变化、生物体所产生的电信号等)。
另外，如后述那样，传感器装置2也可以具备无纺布的电极罩，该电极罩面向车辆用座椅1的外侧，且具有与车辆用座椅1的外表面相同的颜色。通过该电极罩覆盖电极(导电性布帛)，能够使电极(导电性布帛)从外侧看不显眼。
以下，对本发明的实施方式的传感器装置进行说明。
<第一实施方式>
图2是示出第一实施方式的传感器装置2A的一例的图，示出从正面、侧面以及背面的各方向观察而得到的传感器装置2A的外观的例子。图2所示的传感器装置2A具有构成电极的导电性布帛21、22、绝缘性的无纺布31、以及基板10。
导电性布帛21以及22例如包括在由聚酯纤维等化学纤维形成的布帛表面涂覆了铜、镍等金属(导体)而成的布帛、由包含了具有导电性的材料(碳等)的纤维材料形成的布帛等。需要说明的是，后述的实施方式的导电性布帛23～27也由与导电性布帛21以及22相同的材料形成。
无纺布31是具有绝缘性的纤维互相缠绕而延伸为平面状的片状的构件。无纺布31例如由聚酯、聚酰亚胺等合成纤维、玻璃纤维等无机纤维形成。需要说明的是，后述的实施方式的无纺布33～37也由与无纺布31相同的材料形成。
两个导电性布帛21以及22隔着无纺布31而面对。导电性布帛21与无纺布31的正面侧的面结合，导电性布帛22与无纺布31的背面侧的面结合。导电性布帛21以及22与无纺布31的结合例如通过热粘接、缝合来进行。利用热粘接的结合例如通过在导电性布帛21以及22与无纺布31重叠的状态下对要结合的部位施加热量、振动、或者照射激光来进行。另外，利用缝合的结合例如通过使用合成纤维等绝缘体的线使两者缝合来进行。
在图2中，“P1”表示导电性布帛21与无纺布31结合的结合部位，“P2”表示导电性布帛22与无纺布31结合的结合部位。如图2所示，在传感器装置2A的俯视下，导电性布帛21与无纺布31结合的结合部位P1和导电性布帛22与无纺布31结合的结合部位P2错开。即，结合部位P1与结合部位P2不重叠。
如图2所示，在传感器装置2A的俯视下，导电性布帛21与导电性布帛22的重叠部分的多半包括在比导电性布帛22的外缘靠内侧的位置。即，导电性布帛21与导电性布帛22相比整体上较小，在俯视下导电性布帛21的多半部分包括在导电性布帛22的区域的内侧。导电性布帛22与无纺布31结合的结合部位P2在俯视下局部包围导电性布帛21的周围。
另外，如图2所示，在传感器装置2A的俯视下，导电性布帛21的外缘与导电性布帛22的外缘将无纺布31的至少一个面(正面侧的面、背面侧的面)的一部分夹在中间而分隔。即，导电性布帛21的外缘与导电性布帛22的外缘在沿着无纺布31的面的方向上相互分离。
基板10包括与两个导电性布帛21以及22连接的电子电路。该电子电路例如将一方的电极(例如导电性布帛21)作为检测电极，并包括将通过检测电极与生物体的静电电容结合而输入的电信号放大的放大器电路等。在该情况下，另一方的电极(例如导电性布帛22)例如作为被控制为与检测电极同电位的屏蔽电极而发挥功能。或者，基板10的电子电路也可以是检测两个电极(导电性布帛21以及22)所形成的静电电容(互电容)的变化的电路。在该情况下，电子电路将与静电电容的变化相应的生物体的微细的动作作为电信号来检测。导电性布帛21以及22例如通过钎焊而与基板10上的布线图案连接。
图3A～图3C以及图4A～图4B是用于说明图2所示的传感器装置2A的制造方法的一例的图。
图3A示出在无纺布31什么也没有安装的状态。在该图3A的状态下，如图3B所示，在无纺布31的正面侧的面配置导电性布帛21，如图3C所示，无纺布31与导电性布帛21通过热粘接以及缝合的至少一方而结合。
之后，如图4A所示，在无纺布31的背面侧的面配置导电性布帛22，如图4B所示，无纺布31与导电性布帛22通过热粘接以及缝合的至少一方而结合。此时，作为无纺布31与导电性布帛22结合的结合部位P2，选择不与无纺布31和导电性布帛21结合的结合部位P1重叠的部位、且没有设置导电性布帛21的部位。
如以上说明的那样，根据本实施方式的传感器装置2A，电极由导电性布帛21、22构成，在绝缘性的无纺布31的正面侧的面与背面侧的面分别结合有导电性布帛21、22，因此能够确保通气性和柔软性。另外，导电性布帛21、22与无纺布31通过热粘接以及缝合的至少一方而结合，因此通气性、柔软性不会由于结合而受损。并且，无纺布31难以产生纺织物、编织物那样的绽裂，因此能够有效地抑制构成电极的导电性布帛21、22的绝缘性的降低。并且，无纺布31与纺织物、编织物相比容易调整空孔率(间隙的密度)，因此能够与使用状况等相匹配地适当地设定通气性与绝缘性的兼顾。
根据本实施方式的传感器装置2A，在传感器装置2A的俯视下，导电性布帛21与无纺布31结合的结合部位P1和导电性布帛22与无纺布31结合的结合部位P2错开，因此能够将导电性布帛21以及22稳定地绝缘。
根据本实施方式的传感器装置2A，导电性布帛21的外缘与导电性布帛22的外缘在沿着无纺布31的面(正面侧的面、背面侧的面)的方向上相互分离，因此能够将导电性布帛21以及22稳定地绝缘。
<第二实施方式>
图5是示出第二实施方式的传感器装置2B的一例的图。图5所示的传感器装置2B具有构成电极的导电性布帛23、24、绝缘性的无纺布33、34、以及基板10。传感器装置2B中的基板10与已经说明了的传感器装置2A中的基板10相同，也与后述的传感器装置2C以及2D中的基板10相同。以下，以与已经说明了的传感器装置2A的不同点为主来进行说明。
两个导电性布帛23以及24隔着重叠为多重的无纺布33以及34而面对。导电性布帛23与无纺布33的正面侧的面结合，导电性布帛24与无纺布34的背面侧的面结合。在图5中，“P3”表示导电性布帛23与无纺布33结合的结合部位，“P4”表示导电性布帛24与无纺布34结合的结合部位。在图5的例子中，在传感器装置2B的俯视下，导电性布帛23与无纺布33结合的结合部位P3和导电性布帛24与无纺布34结合的结合部位P4错开。即，结合部位P3与结合部位P4不重叠。
在无纺布34的正面侧的面重叠有无纺布33的背面侧的面。在图5中，“Q1”表示无纺布33与无纺布34结合的结合部位。如图5所示，在传感器装置2B的俯视下，结合于导电性布帛23的无纺布33与结合于导电性布帛24的无纺布34结合的结合部位Q1位于导电性布帛23以及24的区域的外侧。
需要说明的是，导电性布帛(23、24)与无纺布(33、34)的结合、无纺布(33、34)彼此的结合与已经说明了的传感器装置2A同样地通过热粘接、缝合来进行。
如图5所示，在传感器装置2B的俯视下，导电性布帛23的外缘与导电性布帛24的外缘将无纺布33以及34的至少一个面(无纺布33的正面侧的面、无纺布34的背面侧的面)的一部分夹在中间而分隔。即，导电性布帛23的外缘与导电性布帛24的外缘在沿着无纺布33以及34的面的方向上相互分离。
图6A～图6C、图7A～图7C以及图8A～图8B是用于说明图5所示的传感器装置2B的制造方法的一例的图。
图6A是示出在无纺布33什么也没有安装的状态。在该图6A的状态下，如图6B所示，在无纺布33的正面侧的面配置导电性布帛23，如图6C所示，无纺布33与导电性布帛23通过热粘接以及缝合的至少一方而结合。
另外，图7A示出在无纺布34什么也没有安装的状态。在该图7A的状态下，如图7B所示，在无纺布34的背面侧的面配置导电性布帛24，如图7C所示，无纺布34与导电性布帛24通过热粘接以及缝合的至少一方而结合。
之后，成为图6C所示的状态的无纺布33的背面侧的面与成为图7C所示的状态的无纺布34的正面侧的面如图8A所示重叠。当无纺布33与无纺布34如图8A所示成为重叠了的状态时，两个导电性布帛23以及24隔着无纺布33以及34而面对。成为重叠了的状态的无纺布33以及34如图8B所示通过热粘接以及缝合的至少一方而结合。此时，在传感器装置2B的俯视下，无纺布33以及34在两个导电性布帛23以及24的区域的外侧的位置处结合。
如以上说明的那样，根据本实施方式的传感器装置2B，面对的两个导电性布帛23以及24被重叠为多重的无纺布33以及34分隔，因此能够将两个导电性布帛23以及24稳定地绝缘。
根据本实施方式的传感器装置2B，结合于一方的导电性布帛23的无纺布33与结合于另一方的导电性布帛24的无纺布34通过热粘接以及缝合的至少一方而结合。通过以与导电性布帛(23、24)和无纺布(33、34)的结合方式相同的方式将无纺布(33、34)彼此结合，能够使制造工序简易化。
根据本实施方式的传感器装置2B，在传感器装置2B的俯视下，结合有导电性布帛23的无纺布33与结合有导电性布帛24的无纺布34在导电性布帛23以及24的区域的外侧的位置处结合，因此能够将导电性布帛23以及24稳定地绝缘。
根据本实施方式的传感器装置2B，导电性布帛23结合于无纺布33的结合部位P3和导电性布帛24结合于无纺布34的结合部位P4错开，因此能够将导电性布帛23以及24稳定地绝缘。
根据本实施方式的传感器装置2B，导电性布帛23的外缘与导电性布帛24的外缘在沿着无纺布33的正面侧的面、无纺布34的背面侧的面的方向上相互分离，因此能够将导电性布帛23以及24稳定地绝缘。
本实施方式的传感器装置2B的上述以外的结构与已经说明了的传感器装置2A的结构相同，传感器装置2B具有与传感器装置2A相同的效果。
<第三实施方式>
图9是示出第三实施方式的传感器装置2C的一例的图。图9所示的传感器装置2C具有构成电极的导电性布帛25、26、绝缘性的无纺布35、36、以及基板10。以下，以与已经说明了的传感器装置2A、2B的不同点为主来进行说明。
如图9所示，两个导电性布帛25以及26隔着无纺布35而面对，并且两个无纺布35以及36面对。导电性布帛25结合于无纺布35的正面侧的面，导电性布帛26结合于无纺布36的正面侧的面。在图9中，“P5”表示导电性布帛25与无纺布35结合的结合部位，“P6”表示导电性布帛26与无纺布36结合的结合部位。在图9的例子中，在传感器装置2C的俯视下，导电性布帛25结合于无纺布35的结合部位P5和导电性布帛26结合于无纺布36的结合部位P6错开。即，结合部位P5与结合部位P6不重叠。
在结合有导电性布帛26的无纺布36的正面侧的面重叠有无纺布35的背面侧的面。在图9中，“Q2”表示无纺布35与无纺布36结合的结合部位。如图9所示，在传感器装置2C的俯视下，结合于导电性布帛25的无纺布35和结合于导电性布帛26的无纺布36结合的结合部位Q2位于导电性布帛25以及26的区域的外侧。
需要说明的是，导电性布帛(25、26)与无纺布(35、36)的结合、无纺布(35，36)彼此的结合与已经说明了的传感器装置2A、2B同样地通过热粘接、缝合来进行。
如图9所示，在传感器装置2C的俯视下，导电性布帛25以及26与无纺布35相比整体上较小，导电性布帛25以及26的多半部分包括在无纺布35的区域的内侧。另外，在传感器装置2C的俯视下，导电性布帛25的外缘与导电性布帛26的外缘将无纺布35的至少一个面(正面侧的面、背面侧的面)的一部分夹在中间而分隔。即，导电性布帛25的外缘与导电性布帛26的外缘在沿着无纺布35的面的方向上相互分离。
图10A～图10C、图11A～图11C以及图12A～图12B是用于说明图9所示的传感器装置2C的制造方法的一例的图。
图10A是示出在无纺布35什么也没有安装的状态。在该图10A的状态下，如图10B所示，在无纺布35的正面侧的面配置导电性布帛25，如图10C所示，无纺布35与导电性布帛25通过热粘接以及缝合的至少一方而结合。
另外，图11A示出在无纺布36什么也没有安装的状态。在该图11A的状态下，如图11B所示，在无纺布36的正面侧的面配置导电性布帛26，如图11C所示，无纺布36与导电性布帛26通过热粘接以及缝合的至少一方而结合。
之后，成为图10C所示的状态的无纺布35的背面侧的面与成为图11C所示的状态的无纺布36的正面侧的面如图12A所示那样重叠。当无纺布35与无纺布36如图12A所示那样成为重叠的状态时，两个导电性布帛25以及26隔着无纺布35而面对。另外，导电性布帛26成为被两个无纺布35以及36覆盖两面的状态。成为重叠的状态的无纺布35以及36如图12B所示那样通过热粘接以及缝合的至少一方而结合。此时，在传感器装置2C的俯视下，无纺布35以及36在两个导电性布帛25以及26的区域的外侧的位置处结合。
如以上说明的那样，根据本实施方式的传感器装置2C，面对的两个导电性布帛25以及26被无纺布35分隔，因此能够将两个导电性布帛25以及26稳定地绝缘。另外，导电性布帛26被夹在两个无纺布35以及36之间，因此能够提高相对于导电性布帛26的绝缘性。
本实施方式的传感器装置2C的上述以外的结构与已经说明了的传感器装置2A、2B的结构相同，传感器装置2C具有与传感器装置2A、2B相同的效果。
<第四实施方式>
图13A是示出第四实施方式的传感器装置2D的一例的图。图13B是示出省略了图13A所示的传感器装置2D中的电极罩41的图示的状态的图。图13A所示的传感器装置2D是利用绝缘性的电极罩41覆盖在已经说明了的图9所示的传感器装置2C中向外侧露出的导电性布帛25的面(与所述无纺布35接触的面的相反侧的面)而成的结构，其他结构与图9所示的传感器装置2C大体相同。但是，传感器装置2C中的无纺布36在传感器装置2D中被替换为比无纺布36尺寸大一些的无纺布36A。
电极罩41由绝缘性的无纺布构成，通过热粘接、缝合而与无纺布36A结合。图13A中的“Q3”表示电极罩41与无纺布36A结合的部位。如图13A所示，电极罩41与无纺布36A结合的结合部位Q3位于导电性布帛25、导电性布帛26的区域的外侧。
这样，在本实施方式的传感器装置2D中，向外侧露出的导电性布帛25的表面被由绝缘性的无纺布构成的电极罩41覆盖，因此能够提高相对于导电性布帛25的绝缘性。另外，通过以与导电性布帛(25、26)和无纺布(35、36A)的结合方式相同的方式将无纺布36A与电极罩41结合，能够使制造工序简易化。
需要说明的是，在将传感器装置2D配置于车辆用座椅1(图1)的内侧的情况下，也可以以电极罩41面向车辆用座椅1的外侧的方式配置传感器装置2D，并且将电极罩41设为与车辆用座椅1的外表面相同的颜色。由此，由面向车辆用座椅1的外侧、且与车辆用座椅1的外表面的颜色同色的电极罩41覆盖导电性布帛25，因此能够使导电性布帛25从外侧看不易显眼，并且能够使电极罩41本身也不易显眼。
以上，对本发明的实施方式的传感器装置进行了说明，但本发明并非仅限于上述的实施方式，在记载于技术方案的本发明的范围内，可以进行各种变形、变更。
图14是示出本发明的实施方式的传感器装置的一变形例的图。
图14所示的传感器装置2E具有绝缘性的无纺布37、以及通过热粘接、缝合而结合于无纺布37的单面的多个导电性布帛27A～27F。在导电性布帛27A～27D所结合的无纺布37的表面预先形成有与导电性布帛27A～27D导通的布线图案51A～51F。布线图案51A～51F例如通过溅射等成膜法而形成于无纺布37的表面。这样，通过使预先形成于无纺布37的表面的布线图案51A～51F与导电性布帛27A～27D导通，可以无需使用连接器等将这些导电性布帛连接到其他电子电路等的布线。因此，能够使组装工序简略化，并且能够削减部件数量。另外，在无纺布37的表面，配置导电性布帛27A～27D的位置变得明确，因此导电性布帛27A～27D的定位作业变得容易，能够提升制造的效率。
在图1中，举出了使传感器装置2配置于车辆用座椅1的内侧的例子，但本发明并不限定于此。在本发明的其他例子中，例如，也可以使传感器装置2配置于车辆的内衬(内装罩)的内侧。在该情况下，通过使用面向内衬的外表面侧、且与内衬的外表面同色的电极罩，能够使被电极罩覆盖的导电性布帛、电极罩自身从外侧看不易显眼。
在上述的第一～第四实施方式中，举出了在无纺布的正面侧和背面侧分别安装一个导电性布帛的例子，但安装于无纺布的各个面的导电性布帛的数量也可以是多个。另外，无纺布的正面侧与背面侧处的导电性布帛的数量可以相同，也可以不同。
在上述的第一～第四实施方式中，作为例子而举出的导电性布帛以及无纺布的形状、尺寸、位置关系等为一例，也可以任意地变更。
