摘要： A chair including a seat assembly (114) having depending leg members (116) and a hollow support frame (118) having at least two open ends (142) terminating beneath the seat and a pair of upstanding, hollow frame members arranged to provide a backrest frame (120) for the chair having at least two open ends (128) extending beneath the seat and in registry with the ends of the support frame, and flexible spring members (50) secured between each pair of members to provide an articulated, flexible spring backrest for the chair. Each spring member includes an elongated, flat spring (56) having its ends secured within a holder (52) (54) which is closed at one end and open at its opposite end for inserting the spring into the holder. The open ends of each holder have stop flange formations (70) protruding outwardly thereon which, effect limitation of the angle of flexure of the spring by engagement of the flanges one with the other.
摘要翻译：一种椅子，包括具有悬挂腿部构件（116）的座椅组件（114）和具有终止于座椅下方的至少两个开口端（142）的中空支撑框架（118），以及一对直立的中空框架构件，用于椅子的靠背框架（120）具有在座椅下方延伸并与支撑框架的端部对准的至少两个开放端（128）以及固定在每对构件之间的柔性弹簧构件（50），以提供铰接的，弹簧弹簧靠背椅子。每个弹簧构件包括细长的扁平弹簧（56），其端部固定在保持器（52）（54）内，该保持器（52）在一端封闭并且在其相对端处开放以将弹簧插入保持器。每个保持器的开口端具有向外突出的停止凸缘结构（70），这通过凸缘与另一个的接合来实现弹簧的弯曲角度的限制。

摘要： A flexible, articulated backrest frame assembly adapted to be installed between a backrest member (98) and a chair seat member (88) to form a flexible backrest for a chair. The frame assembly includes a lower frame part (86) having a pair of hollow, spaced apart frame members (104) joined together at one end of each and open at their opposite ends (110) and an upper frame part (84) having a pair of hollow, spaced apart frame members and open ends (96) in registry with the open ends of the lower frame members. Spring members (50) are secured between the open ends of the frame members to provide an articulated flexible spring connection between the upper and lower frame parts. The frame parts include members (100, 106) for attaching same to a backrest member and chair seat member respectively to form the flexible backrest for the chair. A resilient cover (120) can enclose the backrest frame assembly.
摘要翻译：一种柔性铰接的靠背框架组件，其适于安装在靠背构件（98）和椅子座椅构件（88）之间，以形成用于椅子的柔性靠背。框架组件包括下框架部件（86），该下框架部件（86）具有一对中空间隔开的框架构件（104），每个框架构件的一端在其相对端（110）的一端处连接在一起，并且上框架部件（84）具有一对中空的间隔开的框架构件和与下框架构件的开口端对准的开放端（96）。弹性构件（50）固定在框架构件的开口端之间，以在上部和下部框架部件之间提供铰接的弹性连接。框架部分包括用于分别将其附接到靠背构件和椅子座椅构件的构件（100,106），以形成椅子的柔性靠背。弹性盖（120）可以包围靠背框架组件。

摘要： A chair (11) which includes a seat frame (14) having depending leg members (26) and a pair of upstanding, spaced apart members (40) arranged to provide a lower backrest part for the chair and upper backrest frame part (12) having a pair of spaced apart depending members (18) in registry with the upstanding members, said members being hollow with open extremities (24, 42), and flexible spring means (50) secured between each pair of members to provide an articulated, flexible spring backrest for the chair. Each flexible spring means includes an elongated, flat or blade spring member (56) having its opposite ends secured within a holder member (52, 54) which is closed at one end and open at its opposite end for inserting the spring into the holder. The open ends of each holder have stop flange formations (68, 70) protruding outwardly thereon which, when the holders are spaced apart at their open ends with a slight gap therebetween, effect limitation of the angle of flexure of the spring.
