下面将参考附图并结合实施例来详细说明本公开。
请参考图1和图2，图1和图2示出了本实施例提供的第一种座椅软硬度调节装置，该装置具有一个可集成在座椅中的软充气袋10；软充气袋连接有一个气路11；软充气袋10内填充有柔性填充物20；软充气袋10通过气路11充入或排出气体以调节座椅表面的软硬度；软充气袋10设有配置成限定软充气袋10充气时膨胀高度的限高结构30。
其中，气路11泛指给软充气袋10提供气源的气路结构，例如在本实施例中，气路11包括固定在软充气袋10上的气嘴，与气嘴固定连接的气管；气管的端部连接在电磁阀模组40的泄气口，电磁阀模组40的进气口连接有气源50；电磁阀模组40例如包括串联的二位二通电磁阀和二位三通电磁阀，即二位二通电磁阀的进气口充当整个电磁阀模组40的进气口，二位二通电磁阀的出气口与二位三通电磁阀的进气口连通；二位三通电磁阀的出气口与气管、软充气袋10连接，二位三通电磁阀的泄气口充当整个电磁阀模组40的泄气口；当只给二位二通电磁阀上电时，给软充气袋10充气，当只给二位三通电磁阀上电时，给软充气袋10泄气；当不给任何一个电磁阀上电时，软充气袋10处于保压的状态。电磁阀模组40的上电和断电由控制模块60控制，控制模块60例如可以是以单片机为核心处理器组成的控制电路。当气源50为气泵时，气泵和电磁阀模组40可以集成为一体，控制模块60可以为该集成零件内的控制电路。
在其他实施例中，电磁阀模组40也可以由手动阀代替，此时手动阀包括一个按压气囊，按压气囊的出气口设置有一个出气单向阀，其进气口设置一个进气单向阀；当手动挤压按压气囊时，按压气囊内压力增加，出气单向阀打开，给软充气袋10充气；当松开按压气囊时，按压气囊内压力小，外部空气通过进气单向阀进入到按压气囊内；如此往复操作按压气囊即可实现对软充气袋10的充气。
在本实施例中，一个软充气袋10上设有一个气路11，在其他实施例中，一个软充气袋10也可以设置多个气路11，使得软充气袋10各个部位软硬度均匀。当然了，该装置也可以包括多个软充气袋10。
其中，柔性填充物20可选地为海绵，泡棉等柔性物质。
其中，结合图2，本实施例中，限高结构30包括分布式排列设置的穿透式限高带31和/或内置型限高带32。穿透式限高带31和内置型限高带32的横截面可以是点状、条状、圆形或者蜂窝状等多种形状。
穿透式限高带31的纵截面为工字型，其两端伸出于软充气袋10外，其竖直部分略长于软充气袋10泄气时的正常高度，当软充气袋10充气时，其伸出于软充气袋10外的端部可对软充气袋10表面施加压力，避免其单点膨胀过高。
在可选的实施方式中，限高结构30上设有开口301(图16示出)，具体地，穿透式限高带31和内置型限高带32的中部开设有开口301，配置成导通穿透式限高带31和内置型限高带32两侧的气体。开口301的设置利于软充气袋10内气体的流通。
穿透式限高带31和内置型限高带32的材质为柔性材质，可选的为，尼龙、聚酯薄膜、编制带、编织布、无纺布材料、软塑胶透气膜或带孔洞的塑料片等。
穿透式限高带31由于其穿过软充气袋10的袋体，因此为了保证充气时，其穿透处的密封性，其伸出于软充气袋10外的端部与软充气袋10相邻的表面设有密封圈或者涂有密封胶或者将端部焊接在袋体上，以避免气体从穿透处溢出。
内置型限高带32的两端分别固定在软充气袋10内的上下表面，内置型限高带32的两端可选择地采用以下方式固定在软充气袋内：超声波焊接、胶黏、铆接或穿接等方式。
不管是上述何种方式，内置型限高带32通过将软充气袋10袋体内部的上部和下部拉紧的方式，限定软充气袋10在该处的鼓胀高度。
限高结构30可以单独采用穿透式限高带31或者内置型限高带32的方式；或者如图2所示，同时采用穿透式限高带31和内置型限高带32的方式；不管是哪种方式，本实施例中的均匀分布式的限高结构30使得软充气袋10充气时各个部位的臌胀外形与汽车座椅的泡棉结构的外形一致，与其泄气时的外形也一致，也即实现了与座椅表面原始状态的随形，保证了充气时座椅表面的美观性和舒适性，同时，增加了乘坐人员与软充气袋10对应区域的座椅表面的接触面积，提高了稳定性；同时气体在软充气袋10内不受限高结构30的隔绝，可自由流动。
请参考图3和图4，图3和图4示出了本实施例提供的第二种座椅软硬度调节装置，第二种座椅软硬度调节装置与第一种座椅软硬度调节装置的结构大部分相同，不同之处在于该软充气袋10上开设有若干导风孔道12，配置成将软充气袋10两侧的气流导通。导风孔道12与软充气袋10的充气腔隔绝，软充气袋10的充气腔即为填充有柔性填充物20的腔体，也即配置成容纳充入气体的腔体。
本实施例提供的第二种座椅软硬度调节装置，可应用于具有通风性能的汽车座椅，座椅底部向座椅表面导向的风可从导风孔道12吹出来，最终穿过椅面吹向人体，本实施例的第二种座椅软硬度调节装置的导风孔道12的设置进一步提高了本装置的适用性。
同理，本实施例提供的第二种座椅软硬度调节装置同样适用于吸风型座椅通风。
请参考图5-图7，图5-图7示出了本实施例提供的第一种汽车座椅70，汽车座椅70的靠背71、座垫72和侧翼73上集成有本实施例提供的第一种座椅软硬度调节装置；在其他实施例中，也可将座椅软硬度调节装置设置在汽车座椅的靠背71、座垫72、侧翼73中的任意一个或者多个部位。
在本实施例中，软充气袋10的气源可选地采用以下任意一种方式：
1、由单独设置的微型气泵提供；
2、由汽车车身内的压缩空气提供；
以汽车座椅70的座垫72为例，软充气袋10安装在座垫72的座椅面套75与泡棉结构74之间，软充气袋10的气路11从底部穿过泡棉结构74伸出与气源50连接。
本实施例中，设置在汽车座椅70上各个部位的软充气袋10的气路11上均分别安装有电磁阀模组40，汽车座椅70上的控制模块60通过控制各个电磁阀模组40的通断来分别独立控制各个软充气袋10充放气。各个软充气袋10的独立控制使得各个软充气袋10的充放气可以独立进行，从而使得各个软充气袋10可以形成不同的充放气组合，实现多功能，多种硬度的调节。
可选地，在其他实施例中，汽车座椅上所有软充气袋10分组设置，每组软充气袋10的气路11汇合在支气路上，支气路上安装有支路电磁阀模组；控制模块60通过控制各组支路电磁阀模组的通断来分别控制各组软充气袋10充放气。
软充气袋10的分组规则可以根据位置区域或者实际的使用需求或者控制需求而设定，例如以区域来分组时，所有位于侧翼73的软充气袋10的气路11并联设置，与一个共同的支气路连接；所有座垫72上的软充气袋10并联设置，与一个共同的支气路连接；所有靠背71上的软充气袋10并联设置，与一个共同的支气路连接；分组设置的软充气袋10可以实现总控制，使得同一区域的软充气袋同步动作。
以汽车座椅70的座垫72部位为例，驾乘人员80坐在安装有软充气袋10的座椅上的状态，当软充气袋10处于未充盈状态时，限高结构30弯曲塌缩。软充气袋10及其内部的柔性填充物被压缩，座椅表面处于相对软的状态，人体躯干陷入椅面较深如图6所示。当驾乘人员80坐在椅面，软充气袋10处于充盈状态时，限高结构30相对伸展。软充气袋10及其内部的柔性填充物20仅少许压缩，座椅表面处于相对硬的状态，人体躯干陷入椅面较浅如图7所示。因此本实施例的方案提供了不同软硬度可调的座椅。
请参考图8-图10，图8-图10示出了本实施例提供的第二种、第三种以及第四种汽车座椅70，其在第一种座椅软硬度调节装置的基础上进行改动。具体地，该汽车座椅70的软硬度调节区701叠加设有多层软充气袋10，本实施例以两层软充气袋10为例进行说明。
两层软充气袋10的设置方式具体可以采取以下任意一种方式：
1、相邻叠加，如图8所示，座椅的泡棉结构74邻近座椅面套75的一侧设有配置成放置软充气袋10的软充气袋容留槽76，软充气袋容留槽76的数量有三个，分别为两个对称设置的上软充气袋容留槽76-1和一个下软充气袋容留槽76-2；两个上软充气袋容留槽76-1内并排设有第一软充气袋13和第二软充气袋14；下软充气袋容留槽76-2内设有第三软充气袋15。
其中，第一软充气袋13和第二软充气袋14同时控制充放气，且第一软充气袋13和第二软充气袋14与座椅面套75之间设有柔性衬垫77，限高结构30周围出现局部微小臌胀，产生微小的凹凸不平状态，柔性衬垫77可以弥补这个状态，提升座椅椅面的舒适平整度；当只有位于上软充气袋容留槽76-1内的第一软充气袋13和第二软充气袋14充气，或者只有第三软充气袋15充气时，可以提供中等硬度的座椅座垫硬度；当第一软充气袋13、第二软充气袋14和第三软充气袋15同时充气时，可提供更强硬度的座椅座垫硬度；且当只有第三软充气袋15充气时，乘坐人员由于不直接接触该软充气袋10，硬度的调整从第三软充气袋15到乘坐人员有一定的缓冲间距，进一步提高了硬度调节的舒适性。
2、间隔叠加，如图9所示，两层软充气袋10分别位于靠近座椅面套75的一侧和远离座椅面套75的一侧，由于位于底部的第三软充气袋15与汽车座椅70的支撑骨架78直接接触，为了保护第三软充气袋15，在第三软充气袋15与支撑骨架78之间还设有柔性衬垫77。当然，如果第三软充气袋15的袋体材质较结实，如图10所示，其底部也可以不设柔性衬垫77。
请参考图11，图11示出了本实施例提供的第五种汽车座椅，其在本实施例提供的第一种汽车座椅70的基础上进行改动，如图11所示，泡棉结构74在软充气袋容留槽76靠近座椅面套75的一侧还设有遮盖体容留槽79，配置成放置遮盖体90；遮盖体容留槽79与软充气袋容留槽76呈梯形结构；当软充气袋10充气时，限高结构30周围出现局部微小臌胀，产生微小的凹凸不平状态，遮盖体90可以弥补这个状态，提升座椅椅面的舒适平整度。
遮盖体容留槽79比软充气袋容留槽76更宽，可充分地遮盖软充气袋10的边缘，保护软充气袋10。
上述遮盖体90和柔性衬垫77的材质可以是一样的，例如都为是无纺布、无纺毡、发泡或海绵垫体等柔性材质。
请参考图12-图15，图12-图15示出了本实施例提供第六种汽车座椅70，其在第一种汽车座椅70的基础上进行改动，将软充气袋10的结构替换为第二种座椅软硬度调节装置中的软充气袋结构，如图12所示，此时，软充气袋10与座椅面套75之间还设有加热垫100，汽车座椅70具有通风结构，通风结构包括设置在汽车座椅70底部的导风结构110，泡棉结构74内设有通风孔道74-1，导风结构110导出的气流从通风孔道74-1内流出后继而通过软充气袋10的导风孔道12流通到座椅的设有座椅面套75的一侧。
如图13，该汽车座椅70集成了加热、通风和软硬度调节的功能，汽车座椅70的靠背71，座垫72上设有加热垫100；功能更丰富；通风孔70-1的设置可以依据需要增加，当有通风、软硬度调节和加热功能时，加热垫的基材可选透气性好的基材，或者在加热垫上开口。加热、通风和软硬度调节可集成在一个控制模块上进行控制调节，降低成本。
可选地，如图14所示，与图8-图10对应的，图14中的软硬度调节也可以相应地采用多层调节的方式。结合图14，可以看出，为了配合具有通风结构的汽车座椅70，也可以采用同一层设置间隔的多个软充气袋10，在软充气袋10之间的泡棉结构74上开设通往座椅面套75方向的通风孔道74-1；上部并排设置的第一软充气袋13和第二软充气袋14之间，以及下部并排设置的第三软充气袋15和第四软充气袋16之间均预留有通风孔道74-1的位置；从该图的A部分放大图可以看出，在软充气袋10充气时，限高结构30的周围会呈现局部的臌胀状态，而柔性衬垫77正好可以弥补这个状态，提升座椅椅面的舒适平整度。
可选地，如图15所示，与图11对应的，图15中的汽车座椅70也可以在软充气袋预留槽76的上方设置遮盖体预留槽79，配置成放置遮盖体90。
请参考图16，图16示出了本实施例提供的第一种座椅舒适性调节装置，该装置包括至少一个可集成在座椅中的软充 气袋10；软充气袋10内填充有柔性填充物20；软充气袋10内充入有气体；软充气袋10上还通过连接管路17连接有减震机构120，配置成在软充气袋10受到突变挤压力时，释放软充气袋10内的压力。
本实施例中的软充气袋10如图16所示，其腔体(即，充气腔)内充入有气压，其内的气压一般大于外界的大气压，使得软充气袋10具有一定的硬度。
减震机构120可选地采取以下任何一种方式：
1.如图17所示，减震机构120包括至少一个弹性密封囊121；连接管路17将弹性密封囊121的腔体和软充气袋10的腔体连通；由于软充气袋10内已经预充好了气体，因此，此时软充气袋10内的腔体和弹性密封囊121连通的腔体形成一个完整的密封腔。
一般的密封气袋在道路频繁颠簸时，不断受到压力的反复冲击力，其内压力得不到释放，对于密封气袋的承压能力将造成耗损，另外反复冲击时，密封气袋会骤然增压变硬，骤然变软，突然的硬度变化人体会产生不适的颠簸震动感。而本实施例中的软充气袋10连接有减震机构120，会减缓这个过程，本实施例中的弹性密封囊121的材质为可变性弹性体，如图18所示，当软充气袋10的气体一部分压力大于可变形力时，弹性密封囊121内进入气体，囊体体积增大，当冲击力消失，软充气袋10形变消失，弹性密封囊121的收缩力大于软充气袋10的压力，弹性密封囊121体积缩小，恢复至原来状态，将气体压缩回软充气袋10，软充气袋10恢复至原来的软硬度；因此弹性密封囊121在汽车座椅颠簸的过程中，根据软充气袋10内压力的变化，及时地释放软充气袋内的气压或者回复其气压，减小了软充气袋10内气压的突变量及突变速度，增加人体乘坐的舒适感。
在本实施方式中，弹性密封囊121的材质例如可以为橡胶或者硅橡胶。
2.如图19所示，减震机构120包括气缸122；气缸122具有第一腔体123和第二腔体124；连接管路17将软充气袋10的腔体与第一腔体123互通；气缸122的活塞125的伸出端与复位弹簧126的一端固定连接；复位弹簧126的另一端与固定结构127连接。固定结构例如可以为座椅中固定结构，例如座椅骨架。
当突然增压时，如图20所示，软充气袋10内的一部分空气会被压缩至第一腔体123内，第一腔体123内突增的压力会推动活塞125往第二腔体124的方向移动，复位弹簧126被挤压，软充气袋10的压力变化被减小，软硬度变化减小，减缓整个过程，增加人体乘坐的舒适感。
并且当冲击力消失时，软充气袋10的压力减小，在复位弹簧126的恢复力的作用下，活塞125往第一腔体123的方向移动，活塞125会挤压第一腔体123的气体回流至软充气袋10内，直至复位弹簧126复位，软充气袋10恢复至原始的软硬度状体。
上述只是减震机构120的两种示例说明，还可以采取其他可行的功能类似的方案。
本实施例中，柔性填充物20可选地为海绵，泡棉等柔性物质。
其中，本实施例中，如图16至图21所示，软充气袋10内设有配置成限定软充气袋10充气时局部膨胀高度的限高结构30，限高结构30包括分布式排列设置的穿透式限高带31和/或内置型限高带32。穿透式限高带31和内置型限高带32的横截面可以是点状、条状、圆形或者蜂窝状等多种形状。
穿透式限高带31的纵截面为工字型，其两端伸出于软充气袋10外，其竖直部分略长于软充气袋10泄气时的正常高度，当软充气袋10充气时，其伸出于软充气袋10外的端部可对软充气袋10表面施加压力，避免其单点膨胀过高；
在可选的实施方式中，限高结构30上设有开口301，结合图16，具体地，穿透式限高带31和内置型限高带32的中部开设有该开口301，即，穿透式限高带31开设有开口301，内置型限高带32开设有开口301，配置成分别导通穿透式限高带31和内置型限高带32两侧的气体。开口301的设置利于软充气袋10内气体的流通。
穿透式限高带31和内置型限高带32的材质为柔性材质，可选的为，尼龙、聚酯薄膜、编制带、编织布、无纺布材料、软塑胶透气膜或带孔洞的塑料片等。
穿透式限高带31由于其穿过软充气袋10的袋体，因此为了保证充气时，其穿透处的密封性，其伸出于软充气袋10外的端部与软充气袋10相邻的表面设有密封圈或者涂有密封胶或者将端部焊接在袋体上，以避免气体从穿透处溢出。
内置型限高带32的两端分别固定在软充气袋10内的上下表面，内置型限高带32的两端可选择地采用以下方式固定在软充气袋内：超声波焊接、胶黏、铆接或穿接等方式。
不管是上述何种方式，内置型限高带32通过将软充气袋10袋体内部的上部和下部拉紧的方式，限定软充气袋10在该处的鼓胀高度。
限高结构30可以单独采用穿透式限高带31或者内置型限高带32的方式；同时采用穿透式限高带31和内置型限高带32的方式；不管是哪种方式，本实施例中的均匀分布式的限高结构30使得软充气袋10充气时各个部位的臌胀外形与汽车 座椅的泡棉结构的外形一致，与其泄气时的外形也一致，也即实现了与座椅表面原始状态的随形，保证了充气时座椅表面的美观性和舒适性，同时，增加了乘坐人员与软充气袋10对应区域的座椅表面的接触面积，提高了稳定性；同时气体在软充气袋10内不受限高结构30的隔绝，可自由流动。
请参考图22-图27，图22-图27示出了本实施例提供的第二种座椅舒适性调节装置，如图22所示，其在第一种座椅舒适性调节装置的基础上进行改动，图22中，该软充气袋10连接有至少一个气路11和通过气路11给软充气袋10充气的气源50；软充气袋10通过气路11充入或排出气体以调节座椅表面的软硬度。
本实施例中，软充气袋10内的气压不是固定的，软充气袋10内气体量的多少均可以通过气路11的充气和泄气来实现调节；如图22为软充气袋不充气时候的结构示意图，如图23为软充气袋10充入气体后的结构示意图；
和第一种座椅舒适性调节装置对应的，该第二种座椅舒适性调节装置也可以包括减震机构120，该减震机构120也可以相应地采取弹性密封囊121或者气缸组件的形式。
如图24为软充气袋10内充入气体后且减震机构120为弹性密封囊121的结构示意图，如图25所示，当座椅颠簸时，弹性密封囊121内进入气体，囊体体积增大，当冲击力消失，软充气袋10形变消失，弹性密封囊121的收缩力大于软充气袋10的压力，弹性密封囊121的体积缩小，恢复至原来状态。
如图26为软充气袋10内充入气体后且减震机构120为气缸122等相关组件时的结构示意图；如图27所示，当座椅颠簸时，当突然增压时，软充气袋10内的一部分空气会被压缩至第一腔体123内，第一腔体123内突增的压力会推动活塞125往第二腔体124的方向移动，复位弹簧126被挤压；当冲击力消失时，软充气袋10的压力减小，在复位弹簧126的恢复力的作用下，活塞125往第一腔体123的方向移动，活塞125会挤压第一腔体123的气体回流至软充气袋10内，直至复位弹簧126复位，软充气袋10恢复至原始的软硬度状体。
一般地，减震机构120对于软充气袋10的减震调节适用于软充气袋10内气压已经稳定，即在气路11处于关闭的状态进行。
其中，气路11泛指给软充气袋10提供气源50的气路结构，例如气路11包括固定在软充气袋10上的气嘴，与气嘴固定连接的气管；气管的端部连接在电磁阀模组40的出气口，电磁阀模组40的进气口连接有气源50；如图28所示，电磁阀模组40例如包括串联的两位两通电磁阀41和两位三通电磁阀42，即两位两通电磁阀41的进气口充当整个电磁阀模组40的进气口，两位两通电磁阀41的出气口与两位三通电磁阀42的进气口连通；两位三通电磁阀42的出气口与气管连接，两位三通电磁阀42的泄气口充当整个电磁阀模组40的泄气口；当只给两位两通电磁阀41上电时，给软充气袋10充气，当只给两位三通电磁阀42上电时，给软充气袋10泄气；当不给任何一个电磁阀上电时，软充气袋10处于保压的状态。电磁阀模组40的上电和断电由控制模块60控制，控制模块60例如可以是以单片机为核心处理器组成的控制电路。当气源50为气泵时，气泵和电磁阀模组40可以集成为一体，控制模块60可以为该集成零件内的控制电路。
在其他实施例中，电磁阀模组40也可以由手动阀代替，此时手动阀包括一个按压气囊，按压气囊的出气口设置有一个出气单向阀，其进气口设置一个进气单向阀；当手动挤压按压气囊时，按压气囊内压力增加，出气单向阀打开，给软充气袋10充气；当松开按压气囊时，按压气囊内压力小，外部空气通过进气单向阀进入到按压气囊内；如此往复操作按压气囊即可实现对软充气袋10的充气。
在本实施例中，一个软充气袋10上设有一个气路11，在其他实施例中，一个软充气袋10也可以设置多个气路11，使得软充气袋10各个部位软硬度均匀。当然了，该装置也可以包括多个软充气袋10。
请参考图29，图29示出了本实施例提供的第三种座椅舒适性调节装置，其在在第一种座椅舒适性调节装置的基础上进行改动，如图29所示，该座椅舒适性调节装置还包括配置成调节连接管路17内的流量大小的流量调节机构130。
在本实施例中，如图30所示，该流量调节机构130包括套在连接管路17外的卡箍132；卡箍132包括设有开口的环形部136，环形部136的两个活动端向外平行伸出有第一调节片133和第二调节片134；第一调节片133上开设有螺纹孔1331，第二调节片134上对应螺纹孔1331开设有光滑通孔1341；穿过光滑通孔1341后的螺杆手柄135螺纹固定在螺纹孔1331内。
上述流量调节机构130通过调节环形部136的大小来调节连接管路17的流量；如图31所示，当顺时针转动螺杆手柄135的时候，螺杆手柄135往第一调节片133的方向移动，将第一调节片133和第二调节片134拉近，进而使得卡箍132的环形部136的孔径变小，连接管路17在该处的口径也变小，从而实现了将连接管路17的流量调小；反之，当逆时针转动螺杆手柄135时，可将连接管路17的流量调大。
当乘坐人员对于座椅的硬度较高时，将连接管路17的流量调小可使软充气袋10的硬度变化调小，避免突然从高硬度变软，保持乘坐人员对座椅的高硬度的需求；当乘坐人员对座椅的硬度要求较低时，将连接管路17的流量调大可使得软 充气袋10内的气压快速释放，且不影响乘坐人员的软度需求。
上述流量调节机构130的调节方式为手动调节，在可选地实施方式中，可以采用电动调节，此时该座椅舒适性调节装置还包括微型电机140；微型电机140的输出轴与螺杆手柄135轴向固定连接；微型电机140由控制模块60控制正转或反转；
电动调节的方式可选地采用以下两种形式：
设置输入模块150，例如输入面板，该面板上具有大流量按钮和小流量按钮；当使用者点按大流量按钮后，控制模块60控制微型电机140带动螺杆手柄135转动，将卡箍132张大，以将连接管路17的流量调大；当使用者点按小流量按钮后，控制模块60控制微型电机140带动螺杆手柄135转动，将卡箍132缩小，以将连接管路17的流量调小；
该座椅舒适性调节装置还可以包括配置成检测软充气袋10内压力大小的压力传感器、配置成关断或开启气路11的电磁阀模组40；控制模块60电连接输入模块150；输入模块150配置成输入对应软充气袋10的设定压力；控制模块60配置成接收压力传感器的压力信号，并判断压力信号达到设定压力时，停止给软充气袋10充气；因此，本实施方式中，软充气袋10内的压力按需设定；而连接管路17的流量大小可根据设定压力来调节，也即控制模块60可自动根据软硬度状态的需求信息判断当前应该将流量调大还是调小。
请参考图32和图33，图32和图33示出了本实施例提供的第四种座椅舒适性调节装置，其在第二种座椅舒适性调节装置的基础上进行的改动，其保留了第二种座椅舒适性调节装置的大部分结构，例如包括上述示出的各类减震机构120。不同之处在于，如图32和图33所示，软充气袋10上还开设有若干导风孔道12，配置成将软充气袋10两侧的气流导通。导风孔道12与软充气袋10的腔体隔绝，软充气袋10的腔体即为填充有柔性填充物20的腔体，也即配置成容纳充入气体的腔体。
该座椅舒适性调节装置，可应用于具有通风性能的汽车座椅，座椅底部向座椅表面导向的风可从导风孔道12吹出来，最终穿过椅面吹向人体，本实施例的座椅软硬度调节装置的导风孔道的设置进一步提高了本装置的适用性。
同理，该座椅舒适性调节装置同样适用于吸风型座椅通风。
请参考图5，图5示出了本实施例提供的第七种汽车座椅，如图5所示，该汽车座椅70的靠背71、肩部71-1、座垫72和侧翼73上集成有第一种座椅舒适性调节装置；在其他实施例中，也可将座椅舒适性调节装置设置在汽车座椅的靠背71、座垫72、侧翼73中的任意一个或者多个部位。
以汽车座椅70的座垫72为例，软充气袋安装在座垫72的座椅面套75与泡棉结构74之间，软充气袋10的气路11从底部穿过泡棉结构74伸出与气源50连接。
图5中，设置在汽车座椅70上各个部位的软充气袋10的气路11上均分别安装有电磁阀模组40，汽车座椅70上的控制模块60通过控制各个电磁阀模组40的通断来分别独立控制各个软充气袋10充放气。各个软充气袋10的独立控制使得各个软充气袋10的充放气可以独立进行，从而使得各个软充气袋10可以形成不同的充放气组合，实现多功能，多种硬度的调节。
可选地，在其他实施例中，汽车座椅70上所有软充气袋10分组设置，每组软充气袋10的气路汇合在支气路上，支气路上安装有支路电磁阀模组；控制模块60通过控制各组支路电磁阀模组的通断来分别控制各组软充气袋10充放气。
软充气袋10的分组规则可以根据位置区域或者实际的使用需求或者控制需求而设定，例如以区域来分组时，所有位于侧翼73的软充气袋10的气路11并联设置，与一个共同的支气路连接；所有座垫72上的软充气袋10并联设置，与一个共同的支气路连接；所有靠背71上的软充气袋10并联设置，与一个共同的支气路连接；分组设置的软充气袋10可以实现总控制，使得同一区域的软充气袋同步动作。
以汽车座椅70的座垫72部位为例，驾乘人员80坐在安装有软充气袋10的座椅上的状态，当软充气袋10处于未充盈状态时，限高结构30弯曲塌缩。软充气袋10及其内部的柔性填充物被压缩，座椅表面处于相对软的状态，人体躯干陷入椅面较深如图6所示。当驾乘人员80坐在椅面，软充气袋10处于充盈状态时，限高结构30相对伸展。软充气袋10及其内部的柔性填充物20仅少许压缩，座椅表面处于相对硬的状态，人体躯干陷入椅面较浅如图7所示。因此本实施例的方案提供了不同软硬度可调的座椅。
请参考图8-图10，图8-图10示出了本实施例提供的第八种汽车座椅70，其在第四种汽车座椅70的基础上进行改动，该汽车座椅70的软硬度调节区701叠加设有多层软充气袋10，软硬度调节区701为汽车座椅70上设有软充气袋10的区域；本实施例以两层软充气袋10为例进行说明。
两层软充气袋10的设置方式具体可以采取以下任意一种方式：
1、相邻叠加，如图8所示，座椅泡棉结构74邻近座椅面套75的一侧设有配置成放置软充气袋10的软充气袋容留槽 76，软充气袋容留槽76的数量有三个，分别为两个对称设置的上软充气袋容留槽76-1和一个下软充气袋容留槽76-2；两个上软充气袋容留槽76-1内并排设有第一软充气袋13和第二软充气袋14；下软充气袋容留槽76-2内设有第三软充气袋15。
其中，第一软充气袋13和第二软充气袋14同时控制充放气，且第一软充气袋13和第二软充气袋14与座椅面套75之间设有柔性衬垫77，限高结构30周围出现局部微小臌胀，产生微小的凹凸不平状态，柔性衬垫77可以弥补这个状态，提升座椅椅面的舒适平整度；当只有位于上软充气袋容留槽76-1内的第一软充气袋13和第二软充气袋14充气，或者只有第三软充气袋15充气时，可以提供中等硬度的座椅座垫硬度；当第一软充气袋13、第二软充气袋14和第三软充气袋15同时充气时，可提供更强硬度的座椅座垫硬度；且当只有第三软充气袋15充气时，乘坐人员由于不直接接触该软充气袋10，硬度的调整从第三软充气袋15到乘坐人员有一定的缓冲间距，进一步提高了硬度调节的舒适性。
2、间隔叠加，如图9所示，两层软充气袋10分别位于靠近座椅面套75的一侧和远离座椅面套75的一侧，由于位于底部的第三软充气袋15与汽车座椅70的支撑骨架78直接接触，为了保护第三软充气袋15，在第三软充气袋15与支撑骨架78之间还设有柔性衬垫77。当然，如果第三软充气袋15的袋体材质较结实，如图10所示，其底部也可以不设柔性衬垫77。
请参考图11，图11示出了本实施例提供的第九种汽车座椅70，其在第五种汽车座椅70的基础上进行改动，如图11所示，泡棉结构74在软充气袋容留槽76的靠近座椅面套75的一侧还设有遮盖体容留槽79，配置成放置遮盖体90；遮盖体容留槽79与软充气袋容留槽76呈梯形结构；当软充气袋10充气时，限高结构30周围出现局部微小臌胀，产生微小的凹凸不平状态，遮盖体90可以弥补这个状态，提升座椅椅面的舒适平整度。
遮盖体容留槽79比软充气袋容留槽76更宽，可充分地遮盖软充气袋的边缘，保护软充气袋10。
上述遮盖体90和柔性衬垫77的材质可以是一样的，例如都为是无纺布、无纺毡、发泡、海绵垫体等柔性材质。
请参考图12-图15，图12-图15示出了本实施例提供的第十种汽车座椅70，其在第四种汽车座椅70的基础上进行改动，将软充气袋10的结构替换为第三种座椅舒适性调节装置中的软充气袋结构，此时，软充气袋10与座椅面套75之间还设有加热垫100，汽车座椅70具有通风结构，通风结构包括设置在汽车座椅70底部的导风结构110，泡棉结构74内设有通风孔道74-1，导风结构110导出的气流从通风孔道74-1内流出后继而通过软充气袋10的导风孔道12流通到座椅的设有座椅面套75的一侧。
如图12至图14所示，该汽车座椅70集成了加热、通风和软硬度调节的功能，汽车座椅70的靠背71，座垫72上设有加热垫100；功能更丰富；通风孔70-1的设置可以依据需要增加，当有通风、软硬度调节和加热功能时，加热垫的基材可选透气性好的基材，或者在加热垫上开口。加热、通风和软硬度调节可集成在一个控制模块上进行控制调节，降低成本。
可选地，如图14所示，该软硬度调节也可以相应地采用多层调节的方式。结合图14，为了配合具有通风结构的汽车座椅70，也可以采用同一层设置间隔的多个软充气袋10，在软充气袋10之间的泡棉结构74上开设通往座椅面套75方向的通风孔道74-1；上部并排设置的第一软充气袋13和第二软充气袋14之间，以及下部并排设置的第三软充气袋15和第四软充气袋16之间均预留有通风孔道74-1的位置；从该图的A部分放大图可以看出，在软充气袋10充气时，限高结构30的周围会呈现局部的臌胀状态，而柔性衬垫77正好可以弥补这个状态，提升座椅椅面的舒适平整度。
可选地，如图15所示，该汽车座椅70也可以在软充气袋预留槽76的上方设置遮盖体预留槽79，配置成放置遮盖体90。
