Description

座椅腰托的渐进式调整系统 技术领域
本发明提供一种座椅腰托的渐进式调整系统，特别是关于一种可控制座椅的椅背腰托表面呈现凸起部位沿线性滑移态样的渐进式调整系统，尤其涉及该系统的配气阀、气泵、计时单元以及控制模块，来控制多个气袋组依序消涨，有别于传统技术只能控制单一气袋消长的方法。
背景技术
为使座椅的椅背腰托表面在人体垫靠时的舒适性更为提升，现有技术在椅背的海绵垫体中埋设有机械推杆或凸轮装置，并采用双马达进行双轴向的线性控制，让突出点很容易停止在任意点上，来对椅背表面弧曲度进行渐进式腰托调整，其调整的效果与范围都很好，以使垫体弧曲度改变成适合人体腰部的需求态样。例如：运用于汽车座椅的椅背垫体内，即可随意改变汽车座椅的椅背表面的弧曲度，而调整出使用者需求的腰托效果。
然而，前述在椅背垫体中埋设机械推杆或凸轮装置的技术，其机械式的调整机构体积大而且比较笨重，相当占用设置空间，不利于设置在汽车座椅上，还会造成垫体表面受压不平均的问题，让垫靠者相当不舒适；而且，其突出点为刚性支撑，即便包覆柔软材料还是缺乏缓冲性，也不够舒适，甚至是于当汽车发生碰撞时，会对乘坐者产生不当的集中压力，在使用上相当不安全。
于是，本发明的申请人曾经在椅背的垫体中设置多个气袋，并以气袋的消涨来调整椅背腰托表面弧曲度的技术，例如中国台湾TWI327901、TWM357915，因具有适当的缓冲效果，而为目前与未来的主流，其结构设计通常是将多个气袋容置于垫体与椅背内原有的支撑框架之间，使各个气袋可分别经由配气阀排气，以及通过配气阀接受气泵充气。然而前述通过配气阀控制各气袋的消涨的技术，由于缺少了机械式的双轴向线性控制结构，因此只能简单地调整椅背表面的凸起高度，仍难以达成渐进式腰托调整效果。
另外，本发明在研发过程中，亦曾尝试着将每一个气袋分别利用一个按钮 来控制，然而此种方法与一般控制系统无异，仍然难以达成渐进式的调整效果。有鉴于此，本发明人累积多年相关领域的研究以及实务经验，特发明出一种座椅腰托的渐进式调整系统，能够控制某一个气袋膨胀时让其他相邻的气袋相对应排气，以达成凸起部位沿线性滑移的效果，改善上述现有技术的缺失。
发明内容
本发明的目的在于提供一种座椅腰托的渐进式调整系统，特别是指一种配合操作时序记忆而能够控制座椅的椅背腰托表面呈现凸起部位沿线性滑移态样的渐进式调整系统，以克服现有座椅的气袋消涨技术，因为缺少了机械式的双轴向线性控制结构，只能单独控制一个气袋消涨而简单地调整座椅的椅背表面凸起高度，导致难以达成渐进式调整功能的缺失，由此提高座椅的舒适性。
为达成上述目的，本发明的座椅腰托的渐进式调整系统，是在椅背内相对于人体的腰部位置设有一气袋组，该气袋组是由是由至少三个上下排列而且局部重叠的气袋所组成，各气袋分别经由一配气阀接受一气泵供气来调整各气袋的饱和度，该配气阀及气泵分别接受一控制模块操作，该控制模块包含有一可控制其中一气袋膨胀的第一调节按钮、一能够控制由任一膨胀气袋开始朝向气袋组其中一端依序消涨的第二调节按钮、一能够控制由任一膨胀气袋开始朝向该气袋组另一端依序消涨的第三调节按钮、一能够控制所有气袋消气的第四调节按钮，并且信号连接有一能够记录任一调节按钮控制气袋组中各气袋的充气或泄气时间的计时单元，达到渐进式腰托调整效果。
凭借上述构造，当使用者乘坐于座椅上时，其背部抵靠在椅背表面。此时，使用者可操作该第一调节按钮，以通过该配气阀控制该气袋组其中一气袋接受气泵充气而膨胀，致使椅背表面受到该膨胀气袋支撑而呈现凸起形态，以支撑使用者腰部。接着，使用者可操作该第二调节按钮或第三调节按钮，以通过该配气阀控制由该膨胀气袋至该气袋组其中一端或另一端的各气袋逐一泄气及充气，而使气袋组中的各气袋，由该膨胀气袋开始朝向其中一端或另一端依序消涨，形成相互重叠的相邻气袋其中一气袋泄气缩小、另一气袋充气膨胀的作用，进而让椅背表面受到所述依序消涨的各气袋支撑及释放而呈现凸起部位沿线性滑移的态样，藉以产生以渐进方式调整该气袋组对于使用者腰部的支撑效果，有别于传统技术只能控制单一气袋消长的方法。
值得一提的是，本发明除了采用气袋组中，至少三个呈上下排列且局部重 叠的配置，来达成渐进方式调整支撑效果的目的以外，由于计时单元可以记录配气阀对任一调节按钮操作控制各气袋的充气或泄气的时间，因此通过该计时单元对于各气袋在时间点充气及泄气的精确时序控制，能够实现整体系统的渐进式平顺调节效果，上下调节无突兀感，不但能提供使用者自行通过对气袋的消涨调整，来精确控制该气袋组对腰部的支撑效果，还能模拟机械腰托的功能，达成渐进式的调整效果。并由于气袋非刚性材质，本身具备缓冲及较柔软的特性，让使用者垫靠时的舒适度更为提升，并可供矫正使用者坐姿及脊椎曲度，进而提升使用上的便利性及实用性。
以下进一步说明各元件的实施方式：
实施时，所述至少三个气袋设置在椅背内由上而下依序排置，且上方气袋的底部叠置在下方气袋的顶部外侧。
实施时，该椅背内设有一可供人体背靠的垫体，该气袋组位于该垫体背面相对于人体腰部的位置。
实施时，该气袋组后方设有一用来固定支撑各气袋的背板，该背板安装在椅背内原有的一支撑框架前侧。
实施时，该配气阀内设有一可接受该气泵供气的主气路，以及多条连通该主气路的支气路，多条该支气路分别连接一能够连通该气袋的充气通道，以及一连通外界的泄气通道，且各支气路内分别设有一逆止阀，以及一能够选择该充气通道与支气路或泄气通道连通的电磁阀杆。
实施时，该计时单元记录配气阀对任一调节按钮操作控制各气袋的充气或泄气的时间后，令控制模块在下一次操作时，得以由该计时单元所记录的充气时间和泄气时间点开始控制各气袋依序消涨。
实施时，该第一调节按钮和第四调节按钮设于该控制模块两侧，该第二调节按钮设于该第一调节按钮与第四调节按钮上方，该第三调节按钮设于该第一调节按钮与第四调节按钮下方。
实施时，该控制模块包含有一外壳，所述的第一调节按钮、第二调节按钮、第三调节按钮、第四调节按钮设置在该外壳外部。
实施时，控制模块建置于一触控荧幕装置内，该第一调节按钮、第二调节按钮、第三调节按钮、及第四调节按钮以画面方式呈现在触控荧幕装置上。
实施时，该计时单元设置在配气阀或气泵的电路板上，或与控制模块结合。
相较于现有技术，本发明采用气袋组中，呈上下排列的至少三个气袋局部 重叠的配置，并利用控制模块的各调节按钮配合计时单元来实施不同的时序控制，以实现整体系统的平顺调节效果，上下调节无突兀感，以模拟机械腰托的功能，并由于气袋非刚性材质，本身具备缓冲及较柔软的特性，因此可以让使用者垫靠时的舒适度更为提升，并可供矫正使用者坐姿及脊椎曲度，进而提升使用上的便利性及实用功效。

具体实施方式
请参阅图1至图3，揭示出本发明较佳实施方式的附图，由上述附图说明本发明的座椅腰托的渐进式调整系统，包括在座椅1的椅背11内相对于人体腰部的位置设有一气袋组2，该气袋组2是由至少三个上下排列且局部重叠的气袋所 组成。图示中，该座椅1可为汽车座椅、按摩座椅或一般座椅。该椅背11表面12可供人依靠，所述多个气袋在椅背11内由上而下依序排置，且上方气袋的底部叠置在下方气袋的顶部外侧；此实施例所示的气袋包括有三个纵向定位在椅背11内的一第一气袋21、一第二气袋22及一第三气袋23，而使第一气袋21位于该气袋组2的顶端，该第三气袋23位于该气袋组2的底端，且第二气袋22位于该气袋组2中间。
该椅背11内设有一可供人体背靠的缓冲用海棉或泡绵垫体13，该垫体13可供置放在座椅1的椅背11前方竖立使用，而使该气袋组2位于该垫体13背面相对于人体腰部的位置。为了方便模块化生产，该气袋组2后方设有一用来固定支撑气袋组2的背板3，而使该气袋组2容易设置在座椅1的椅背11内部。以汽车座椅1为例，该座椅1的椅背11内原本即设有一具备弹性的支撑框架14，安装时可将该背板3固定在支撑框架14前侧，使该气袋组2借以定位，并且提供该气袋组2充气时的反向支撑力，接着再将垫体13的背面贴靠于气袋组2前侧，以方便安装，而使该气袋组2位于该垫体13与支撑框架14之间。
此外，由于人体背部脊椎在腰部位置为略微向前弯曲的曲线，因此本发明实施时，该气袋组2是设置在垫体13背面相对于人体的腰部位置，当该第一气袋21、第二气袋22及第三气袋23充气时，即可以隔着垫体13朝椅背11表面12向前凸出，进而对人体的腰部产生支撑作用。
如图2及图4所示，该第一气袋21、第二气袋22及第三气袋23分别经由一配气阀4接受一气泵5供气，以调整各气袋的饱和度。该配气阀4可设于背板3后面或椅背11内的支撑框架14上，且配气阀4内设有一可接受该气泵5供气的主气路41，以及多条连通该主气路41的支气路42，每一支气路42分别设有一可连通该第一气袋21、第二气袋22和第三气袋23充气的充气通道43，以及一连通外界的泄气通道44，且每一支气路42内分别设有一逆止阀421，以及一利用电磁铁驱动的电磁阀杆45，该电磁阀杆45的作动与否，能够选择该充气通道43与支气路42或泄气通道44连通。该主气路41上更设有一安全泄压阀46，当主气路41内压过大时，该安全泄压阀46可进行安全泄压的动作。该气泵5可设于背板3旁侧或椅背11内的支撑框架14上，且气泵5通过一管体61接通主气路41，前述第一气袋21、第二气袋22及第三气袋23与所对应的充气通道43之间可分别通过一管体62相互接通。
当欲对该第一气袋21进行充气时，可开启该气泵5运作，直接令高压空气 自主气路41进入支气路42及充气通道43，令空气流入该第一气袋21内使其膨胀，待其膨胀至所需大小时，停止气泵5运作即可通过逆止阀421的逆止作用，使该第一气袋21保持在膨胀状态，而提供支撑的效果。当欲对已呈膨胀状态的第一气袋21进行消气时，可令配气阀4控制该电磁阀杆45阻断充气通道43与支气路42之间的连通状态，同时让充气通道43与泄气通道44连通，则第一气袋21内的空气即反向通过充气通道43，再由泄气通道44排出至外界大气。该配气阀4控制该第二气袋22和第三气袋23的充气及泄气方式与上述相同，故不再赘述。
请参阅图5及图6所示，该配气阀4及气泵5分别接受一控制模块7操作来对气袋组2的各气袋充气，该控制模块7包含有一第一调节按钮71、一第二调节按钮72、一第三调节按钮73、一第四调节按钮74，并信号连接有一计时单元8；图示中，控制模块7包含一外壳75，各调节钮设置在外壳75上，以提供给使用者一个方便操作的独立操作界面。而计时单元8则可以设置在配气阀4或气泵5的电路板上，用以记录任一调节按钮控制配气阀4对气袋组2中各气袋的充气或泄气时间；当然，计时单元8，亦可以结合在控制模块7的外壳75内。
如图7所示，上述控制模块7实际实施时，亦不排除与座椅原有的操座控制系统结合。以汽车座椅1为例，较先进的汽车可以通过车内的触控荧幕装置来操作调整汽车座椅1的前后、高低、椅背倾角等，因此本发明实施时如图所示，控制模块7可以内建于一触控荧幕装置76内，使第一调节按钮71、第二调节按钮72、第三调节按钮73、及第四调节按钮74以画面方式呈现在触控荧幕装置76上，来达成对气袋组2的各气袋控制调整的目的。
此外，控制模块7设置在触控荧幕装置76上的方式，亦可以利用触控荧幕装置76的多点触控功能，以水平向X轴和垂直向Y轴，形成上下、左右的方式来操作，例如：图7按压第一调节按钮71的操作模式，亦可以为手指向左滑动。
如图6所示，实施时，各调节钮排置时，前述第一调节按钮71和第四调节按钮74可设于该控制模块7两侧，该第二调节按钮72可设于该第一调节按钮71与第四调节按钮74上方，该第三调节按钮73可设于该第一调节按钮71与第四调节按钮74下方，而使该第一调节按钮71、第二调节按钮72、第三调节按钮73及第四调节按钮74排列成上、下、左、右等四方向可调整型态，搭配前 述各调节按钮的控制各气袋依序充气或消气的动作，让使用者操作时可以有直觉式的操作感；同样地，这种利用水平向X轴和垂直向Y轴来完成第一调节按钮71到第四调节按钮74，亦可以为一能够水平向X轴和垂直向Y轴实体操作杆。
当使用者乘坐于座椅1的坐垫上时，其背部抵靠在椅背11表面12，若使用者首先按压第二调节按钮72、第三调节按钮73或第四调节按钮74，因各气袋并无膨胀状态，因此感觉不到任何动作。如图7所示，本发明设定为需按第一调节按钮71，则可经由配气阀4控制该气袋组2中间的第二气袋22充气膨胀，致使椅背11表面12通过垫体13受到该膨胀的第二气袋22支撑而呈现凸起形态，以支撑使用者腰部。此时该计时单元8会记录停止充气的时间，藉以决定后续各气袋的开始充气时间。当第二气袋22充气膨胀呈满气压状态时，若使用者仍持续按住第一调节按钮71，该控制模块7可自动停止充气动作；当然，控制模块7亦可以预载一个设定时间，在计时单元8记录充气时间到达该设定时间时停止充气。
如图8所示，若此时使用者按压第二调节按钮72，则第二气袋22泄气缩小，同时第一气袋21充气膨胀，致使椅背11表面12通过垫体13受到该膨胀的第一气袋21支撑而呈现凸起形态，则垫体13表面的凸起部位，即形成由第二气袋22的位置，逐渐向上偏移到第一气袋21的位置，直到第一气袋21膨胀至饱和状态，或使用者停止按压，或计时单元8记录充气时间到达设定时间为止。
相反地，若如图9、图10所示按压第三调节按钮73，则第二气袋22泄气缩小，且第三气袋23充气膨胀(如图10所示)；直到第三气袋23膨胀至饱和状态，或使用者停止按压时，或计时单元8记录充气时间到达设定时间为止。
前述图8所示过程中，当使用者按压第二调节按钮72，使垫体13表面凸起部位由第二气袋22的位置向上偏移到第一气袋21的位置后，此时按第三调节按钮73，则如图9所示，第一气袋21泄气缩小，且第二气袋22充气膨胀，直到第二气袋22膨胀呈满气压状态时，若持续按第三调节按钮73，则如第十图所示，第二气袋22泄气缩小，且第三气袋23充气膨胀，致使椅背11表面12通过垫体13受到该膨胀的第三气袋23支撑而呈现凸起形态，以支撑使用者腰部，直到第三气袋23膨胀呈满气压状态时，若再持续按第三调节按钮73则无动作。此时，若再按压第二调节按钮72，则该气袋组2依据第三气袋23、第二气袋22和第一气袋21的顺序逐一产生消涨动作；上述各气袋的调整只是举例持续按压 状态，举例持续按压状态，调整过程中只要各气袋达到使用者感觉舒适的程度后，放开调节按钮即可随时停止，并通过前述计时单元记录当前状态、使控制模块7下一次操作时，由该计时单元8所记录的充气时间和泄气时间点开始控制各气袋依序消涨。
凭借上述说明可知，本发明可通过该控制模块7、配气阀4及计时单元8控制该气袋组2中的任一气袋开始，朝向其中一端或另一端逐一泄气及充气，形成相邻的一气袋泄气缩小且另一气袋充气膨胀的作用，致使椅背11表面12通过垫体13受到所述依序消涨的第一气袋21、第二气袋22和第三气袋23支撑及释放，而呈现凸起部位沿线性滑移的态样，产生以渐进方式调整对于使用者腰部的支撑效果。而且，该气袋组2对于椅背11表面12呈现凸起部位的上下移动调节极平滑顺畅，无相对的突兀感，实现了腰托的渐进式调节，让支撑弧度符合人体工学要求，使椅背11结构能作为矫正使用者坐姿及脊椎曲度的用。
再者，当上述使用者通过任一调节按钮对该气袋组2其中任一气袋(例如：第三气袋23)进行充气或排气后，若松开调节按钮，则计时单元8即可记忆该调节按钮的按压时间作为下一动作的起始点；例如：前次调整到第三气袋23刚开始充气、第二气袋22刚开始排气，此时，若按该第一调节按钮71，可继续对第三气袋23充气，若按该第二调节按钮72或第三调节按钮73，则以第三气袋23为起始点做充泄气动作。若按该第四调节按钮74，则第一气袋21、第二气袋22和第三气袋23都同时泄气。如此，通过第一调节按钮71、第二调节按钮72、第三调节按钮73和第四调节按钮74，即可以控制至少三个气袋依序消长，并利用该计时单元8记录充气及泄气时间，因此能够精确控制三个或三个以上的气袋，且顺序不会搞混。
特别值得一提的是，图7到图11中，该计时单元8能够记录任一调节按钮(71～74)控制气袋组2中各气袋(21～23)的充气或泄气时间，使控制模块7下一次操作时，由该计时单元8所记录的充气时间和泄气时间点开始控制各气袋依序消涨，进而具备记忆及时序控制来达成渐进式调节的作用，并实现一键恢复的功能。
据此，本发明有别于传统技术只能控制单一气袋消长的方法，采用多个气袋局部重叠的配置，结合该配气阀4对各气袋不同的充泄气时间，并由控制模块7及计时单元8实施不同的时序控制，以实现整体系统的平顺调节效果，上下调节无突兀感。可提供使用者自行通过对各气袋的渐进式消涨调整，来精确 控制该气袋组2对腰部及背部的支撑效果，实现背部腰托渐进式调整支撑作用，以模拟机械腰托的功能，并由于气袋组2非刚性材质，本身具备缓冲及较柔软的特性，让使用者垫靠时的舒适度更为提升，并可供矫正使用者坐姿及脊椎曲度，进而提升使用上的便利性及实用功效。
以上的实施说明及附图所示，举例说明本发明的较佳实施例，并非以此局限本发明；举凡与本发明的构造、装置、特征等近似或相雷同者，均应属本发明的创设目的及申请专利范围内，谨此声明。
