摘要： A chair seat that is movable between an upright and a forward position includes a spring mechanism that biases the seat toward the upright position. The spring mechanism includes camming structures that utilize both compressional and torsional forces from the spring to bias the seat toward the upright position. The compression of the spring exerts a positive force that must be overcome before the seat can be moved out of its upright position. The chair seat is constructed from a number of discrete components that are secured together without the use of welding or separate fasteners, such as via snap-fits. The discrete components include positioning tabs, special shapes, and other features that prevent them from being improperly assembled. The components of the chair seat may all be constructed out of suitable durable plastics, such as polypropylene, polyethylene, polycarbonate, and glass filled thermoplastics.
摘要翻译：可在直立位置和前位置之间移动的椅子座包括弹簧机构，其将座椅朝向直立位置偏置。弹簧机构包括利用来自弹簧的压缩力和扭转力将座椅偏压到直立位置的凸轮结构。弹簧的压缩在座椅能够移出其直立位置之前施加必须克服的正向力。椅座由许多分立的部件构成，这些组件固定在一起，而不需要使用焊接或单独的紧固件，例如通过卡扣配合。分立组件包括定位凸片，特殊形状和其他功能，可防止组件错误组装。椅子座椅的部件都可以由合适的耐用塑料制成，例如聚丙烯，聚乙烯，聚碳酸酯和玻璃填充的热塑性塑料。

摘要： A back for a chair includes fabric panel with a flexible carrier attached to the panel around its periphery. The carrier is configured to be secured along a bottom edge to a bottom portion of a chair back frame member. The carrier is also secured to two vertical frame supports at its two upper corners. Preferably, the upper carrier and frame connections are ball and socket joints. A lumbar support is provided that is easily height adjustable, by providing tension to the back frame and requires no screws or adjustment knobs in its adjustment mechanism.

摘要： A chair back is disclosed and includes a mesh material connected to a two-piece carrier, the carrier being deformable and stretchable. The carrier has a bottom edge including a groove and is engageable by tabs attached to a transverse member of a chair frame assembly. The upper ends of the carrier each includes an opening for receiving a spherical end portion of the upper end of the chair frame assembly. Engagement of the carrier with the chair frame assembly is accomplished by stretching the carrier and mesh between the transverse member and the spherical end portions. The chair back includes a lumbar support which is mounted to slide along the side edges of the carrier and along vertical supports of the chair frame assembly, the lumbar support causing the chair to tension forwardly. The chair back is pivotal under the influence of a chair user and is pivotally connected to the chair seat so as to cause the chair seat to also pivot in response.

摘要： A plastic contoured seat back includes an inner and an outer shell affixed together. The inner shell includes a three dimensionally curved front surface and a two-dimensionally curved back surface. The inner shell may include an internal rib adjacent the top of the shell that is shaped differently from the top edge of the inner shell. The internal rib is adapted to allow the inner shell to be cut adjacent the internal rib so that the inner shell can be varied in shape. The shell may also include indentations on the back side of the shell adjacent the corners of the inner shell. The indentations are dimensioned to receive overlapping fabric that is pulled around the corners such that the fabric on the back of the shell adjacent the corners does not project outwardly more than the fabric elsewhere, despite the overlapping of the fabric at the corners. The inner shell may also include a plurality of uniquely identified holes adapted to allow a variety of different ornamentation to be attached to the inner shell.
摘要翻译：塑料轮廓的座椅靠背包括固定在一起的内外壳。内壳包括三维弯曲的前表面和二维弯曲的后表面。内壳可以包括邻近壳的顶部的内部肋，其与内壳的顶部边缘不同地成形。内肋适于允许内壳邻近内肋切割，使得内壳可以变形。壳体还可以包括邻近内壳角部的壳体后侧的凹陷。凹痕的尺寸被设计成接收被围绕角落拉扯的重叠织物，使得邻近角部的外壳背面上的织物不会比其他地方的织物向外突出，尽管织物在拐角处重叠。内壳还可以包括多个独特地识别的孔，其适于允许各种不同的装饰物附接到内壳。
