Abstract

本发明涉及一种座椅壳架，或是座椅或是躺椅，其支撑面由弯曲延伸的成型件保持，其特征在于：这些成型件是分段的，并在分段过渡位置上具有转动和/或摆动轴承，从而使得一个成型件的端部确定下一成型件的方向，通过相接的成型件的相对转动，在成型件有很小的摆动范围时使支撑面发生大的偏转或者使成型件的作用部位加长，通过转动/摆动轴承来保证紧接着的部件对正。

Description

具有倾斜－轮廓配合机构的座椅壳架
本发明涉及一种座椅壳架(Sitzschale)，或是座椅或是躺椅，其支撑面由弯曲延伸的成型件保持，其特征在于：这些成型件是分段的，并在分段过渡位置上具有转动和/或摆动轴承，从而使得一个成型件的端部确定下一成型件的方向，通过相接的成型件的相对转动，在成型件有很小的摆动范围时使支撑面发生大的偏转或者使成型件的作用部位加长，通过转动/摆动轴承来保证紧接着的部件对正。此外，座椅或躺椅还具有下述特征：支撑面是一个在一个方向上可挠曲的具有侧面部件的绷料(Bespannung)的结构件，该侧面部件在绷料方向上是刚性的、但在长度方向上是可挠曲的并且将绷料传递到定位架上。
本发明的目的是保证实现一种符合背部弯曲的座椅或躺椅支撑，该支撑符合自然放松的身体姿态，而不必进行自身运动的调整。
这个目的由此而实现，即，靠背轮廓在直立的坐姿下与可变的靠背倾斜适配。此外，为了防止在向后靠得很厉害的姿态时向前滑动，通过较弱地构成脊柱前凸支撑(Lordosenstuetzung)来加大座椅倾斜。结构适配地，在上端后背处，头部位置姿态近乎垂直，从而起到了放松肩部和颈部的作用。
图5示出在递进顺序1至4中的轮廓变化，表示出在向后倚靠时，轮廓变化是如何按照本发明的结构特征进行的。
通过下面的附图1至8描述本发明：
图1和2由一个处在直立位置的座椅的侧面和正面视图示出成型件1的起始和终端轮廓。支撑面14被构成一个形状，该形状通过成型件1的转动而改变。头部件9在其上端借助连接件10这样地固定，即，使连接件总是与成型件1的端部对正。
所述这些成型件1这样支承在支座2上，使得仅仅通过1和2的相对转动就可以得到靠背倾斜的变化，如在图1和图3中所示的那样，并由此也改变靠背轮廓。
图3和4示出处在向后靠的位置的同一座椅的侧视图和正视图。
所述支座2在壳体3中可转动地支承，并如图3所示允许在底座6上翻转。
2的转动通过杠杆4和推杆5而引起从壳体3到底座6的翻转，由此使支座2同时反向同步。因此使靠背倾斜、靠背轮廓和座椅倾斜配合作用。
图6示出具有气压弹簧12和拉杆13的铰接机构11。在这里表示出在向后靠时可锁定的气压弹簧是如何一起移动的。气压弹簧产生对身体重量的反作用力和在各个位置上的止动性。
图7示出优选由可挠曲的侧面部件17所组成的支撑面14，该侧面部件通过绷料16缝制并将定位架15的张紧力均匀地传到绷料上。如果所述绷料是永久弹性的，则所述定位架可以是刚性的。如果当绷料适配于身体时，定位架可以向后摆动，则定位架15可以平坦地顶靠在绷料上。
侧面部件17在后面用弹性织物双叠并缝制，因此出现一个袋，在袋中成型件1可以移动并良好地顶靠支撑面14。
图8示出调整绷料硬度的方法，绷料硬度例如对于脊柱前凸支撑部位是有重要意义的，通过转动在轴承19中的手轮18可以改变定位架15的跨度。所述手轮和定位架配有螺纹，该螺纹起到改变长度的作用。
本发明对于健康保健方面是有益的，并且无需外部能源输入地、有利于环境地工作。
本说明书后附附图标记清单。

Claims (2)

1. 一种斗式座椅，包括：一个座位；一个从所述座位立起延伸的靠背，靠背具有一柔性的支撑面(14)和至少两个用于支承及保持所述支撑面的竖向的弯曲成型件(1)，支撑面沿着竖向的弯曲成型件的整个纵长范围与所述成型件接合；其特征在于，各成型件(1)分别以其端部段可转动地支承在支承部件(2，10)中，所述支承部件本身可相对于底座(6)或其基础构件进行转动或摆动，使得在成型件转动到不同位置时支承部件也相应地发生转动或摆动，而保持支承部件的走向与支承在其内部的成型件端部段的延伸方向相一致，由此，成型件的转动与支承部件的转动或摆动配合作用，在支撑面倾斜度发生变化的同时改变靠背的形状。
2. 如权利要求1所述的斗式座椅，其特征在于，所述支撑面(14)是一个具有侧面部件(17)的绷料(16)的结构件，该侧面部件是可挠曲的并且将定位架(15)的张紧力均匀地传到绷料上。
