本申请要求2007年6月25日提交的德国申请No.10 2007 029 0167.3的优先权，其全部公开内容特此并入本申请中。 
技术领域
本发明涉及可枢轴转动到倚靠位置(reclined position)和折叠位置的机动车座椅。 
背景技术
机动车工业的竞争特性提供了发展改善的交通工具系统的连续推动力。尤其，交通工具内部部件因其与交通工具操作者和乘坐者的相互影响而特别地重要。其它设计压力来自于政府对改善燃料效率的规划和要求。后面的这些考虑常常与审美特征不一致，且燃料效率更高的交通工具往往具有非常有限的乘客室空间。 
许多交通工具包括放置在有一定限制的空间中的后部交通工具座椅。改善此类座椅舒适性的策略是需要的。在典型的交通工具座椅中，后部座椅和前部座椅通常都具有缓冲角度(cushion angle)，该角度不能很好地适宜于所有乘坐者，当然，这些角度可以是任意大小。在所有交通工具中，且尤其在较小的交通工具中，最好是具有折叠并提供增加的后面储存空间的座椅。 
因此，需要在已有技术中改进交通工具座椅，其为交通工具乘坐者提供增加的舒适性，而且可折叠。 
发明内容
本发明通过在至少一种实施方式中提供可定位在一个或多个升起位置的交通工具座椅解决了已有技术的一个或多个问题。这种实施方式的交通工具座椅包括座椅底部和座椅靠背。座椅底部包括前部部分和后部部分。座椅靠背围绕座椅底部枢轴地安装。座椅靠背可定位在倚靠位置和折叠位置。尤其，座椅靠背以及因此的交通工具座椅可有利地折叠到大致放平的构型。此特征使这种座椅对于增加交通工具中的储存空间是有用的。可枢轴转动的联接系统(pivotable link system)特质上将座椅底部的前部部分定位在降低位置以及一个或多个升起位置。这种可定位性被称为倾斜可调节性。除了提供倾斜可调节性外，本实施方式的交通工具座椅能够被折叠和/或被定位在倚靠位置。有利地，本发明的交通工具座椅提供了增加的乘坐者舒适性(尤其当定位成后部座椅时)以及增加的储存空间。 
本发明提供一种交通工具座椅，包括：

在一实施方式中，所述联接件可包括杆，所述杆与所述扇形齿轮通信。 
在一实施方式中，所述联接系统可进一步包括连接到所述扇形齿轮的夹紧托架，所述夹紧托架啮合所述杆。 
在一实施方式中，所述联接系统可包括与使用者操作的旋钮通信的小齿轮，所述小齿轮将所述扇形齿轮定位在一个或多个传动位置。 
在一实施方式中，所述座椅靠背可适合于向前折叠。 
在一实施方式中，所述座椅靠背可与所述联接系统通信，使得将所述座椅靠背定位在折叠位置促使所述座椅底部移动到向前延伸的位置，从而适应折叠的所述座椅靠背。 
在一实施方式中，所述座椅靠背可由第一滑轮系统耦合到所述联接系统，所述第一滑轮系统脱离所述座椅底部，使得所述座椅底部可被定位在所述向前延伸的位置。 
在一实施方式中，所述座椅靠背可由第二滑轮系统耦合到所述联接系统，使得当所述座椅靠背被折叠时，所述座椅底部被放置在所述向前延伸的位置。 
在一实施方式中，交通工具座椅可进一步包括扭力弹簧，所述扭力弹簧将所述座椅底部向前偏置到延伸位置或向后偏置到降低位置。 
在一实施方式中，交通工具座椅可进一步包括轨道，所述座椅底部在所述轨道上滑动，同时倾斜到基本放平的折叠位置。 
在一实施方式中，所述座椅靠背可适合于向后倾斜。 
本发明提供一种交通工具座椅，包括： 
座椅底部，其具有前部部分和后部部分； 
座椅靠背，其可相对于所述座椅底部枢轴转动，所述座椅靠背可定位在倚靠位置和向前位置；以及

贯穿该申请，在引用了出版物的地方，这些出版物的公开内容的全部特此以引用方式并入本申请，以更完整地描述本发明所属的技术水平。 
参照图1，示意性显示了座椅底部被定位在各种高度以适应使用座椅的交通工具乘坐者的能力。图1显示了座椅底部从最低位置到中间位置以 及然后到最高位置的转变。交通工具座椅10包括座椅底部12、座椅靠背14以及头部保护物16。座椅底部12包括前部部分20和后部部分22。座椅靠背14枢轴地安装到托架24，以围绕座椅底部12移动。可枢轴转动的联接系统30能够将座椅底部12的前部部分20定位到降低位置32、中间升起位置34和最高位置36。应理解，也可在本实施方式内设想其他的中间位置。前部部分20的移动由可枢轴转动的联接系统30的移动实现。可枢轴转动的联接系统30包括联接件40和托架42，该托架42可移动地连接到联接件40。联接件40沿方向d1的旋转促使托架42移动，因此如以上陈述的移动座椅底部12。通常，联接件40由使用者旋转与滑轮44通信(in communication with)的旋钮而旋转，滑轮44又与联接件40通信。在本发明的改进中，该旋钮可以用一只手操作。前部部分20的移动也伴随着座椅底部12沿方向d2的平移移动。导向装置48连接到座椅底部12。导向装置48引导座椅底部12沿支撑元件50移动(即，滑动)，支撑元件50起轨道的作用，同时也适应当前部部分20升高时发生的倾斜运动。 
参照图2，显示了交通工具座椅的实施方式折叠的示意图。图2显示了座椅从设计位置到折叠位置的转变。在这种变化形式中，座椅靠背沿方向d3旋转，以从升起位置60移动到折叠位置62，并在需要时返回。座椅靠背14的移动耦合到联接系统30的移动，使得当座椅靠背14折叠时，联接系统30将前部部分20移动到升起位置64，然后到延伸位置70。座椅底部12以这种方式的移动伴随沿方向d2的平移运动，使得当座椅靠背14完全折叠时，座椅底部12定位在延伸位置70。在折叠期间，座椅底部12和座椅靠背14的耦合运动经由连接到缆绳66的滑轮44完成。缆绳66在没有较大运动的机架内移动。当座椅靠背14被折叠时，缆绳66被拉动成使得滑轮44和联接件40如前面陈述的那样旋转。 
参照图3，提供了显示图1和图2交通工具座椅移动到倚靠位置的示意图。在这种变化形式中，座椅靠背沿方向d3旋转，以从升起位置60移动到倚靠位置72，并在需要时返回。 
参照图4和图5，提供了用于升起座椅底部12的联接系统的变化形式。图4是联接系统30的侧视图，而图5是联接系统30的透视图。联接系统 30包括联接件40、40’。联接件40通过托架42枢轴地连接到座椅底部框架80，而联接件40’通过托架42’枢轴地连接到座椅底部框架80。小齿轮82的旋转促使扇形齿轮84沿方向d1围绕枢轴点88旋转。中断系统(breaking system)与小齿轮82相关联，以便避免座椅加载时松垂。枢轴点88相对于支撑框架90被固定。支撑框架90可直接地或间接地固定到交通工具底板。在图4和图5中描绘的具体变化形式中，扇形齿轮通过杆92移动联接件40。杆92由夹紧托架(clasping bracket)94和钩形托架(hookbracket)96固定到扇形齿轮84。夹紧托架94连接到扇形齿轮84，而钩形托架可围绕杆100枢轴转动。弹簧102偏置钩形托架96，使得杆92被保持在夹紧托架94内。在折叠期间，如以上结合图2描述所陈述的，联接件40通过经缆绳110打开钩形托架96而与夹紧托架94脱离。缆绳110耦合到座椅靠背的折叠，以完成此打开。联接件40的脱离允许座椅底部旋转到延伸位置70，这与当座椅折叠时陈述的一样。滑轮44任选地经轮轴112连接到扇形齿轮84。在一变化形式中，虽然扇形齿轮84和滑轮44经轮轴112连接，但是扇形齿轮84能够独立于滑轮44旋转。这种特征允许交通工具座椅具有记忆功能。具体地，由旋钮定位在升起位置的座椅底部能在折叠后复原到与展开时相同的位置。在本实施方式的另一改进中，受扭杆簧(torsion rod spring)98通过轮轴112。受扭杆簧98可将座椅底部12向前偏置到延伸位置70或向后偏置到降低位置32。最后，在本实施方式的又一变化形式中，联接系统30是本领域的技术人员已知的常规的倾斜调节系统(recliner system)。 
参考图6，提供了显示使座椅靠背的折叠与座椅底部的移动耦合的示意图。在折叠期间，座椅靠背14的移动经由滑轮系统120、122，经由缆绳110、66耦合到座椅底部12的移动。当座椅靠背14被折叠时，缆绳110如上所陈述的脱离钩形托架96。相似地，由于当座椅靠背14折叠时缆绳66的缩回，滑轮系统122促使滑轮44将座椅底部12旋转到前部位置70。图6也显示了旋钮130，其由使用者使用，以将座椅底部12定位在一个或多个升起位置。 
显示和描述了本发明的实施方式，但是并不意味着这些实施方式显示 和描述了本发明的所有可能形式。而且，在说明中使用的词汇是描述性的词汇而非限定性的词汇，且可以理解，可以做出各种改变而不偏离本发明的主旨和范围。
