    • A tensionable internal reinforcing structure for a mattress, seat cushion or the like, comprising one or more elongate tension members each traversing a column of mutually abutting pressure elements to form a collapsible armature, includes several wedge pieces which are inserted between adjoining pressure elements to impart a desired curvature to the armature. The wedge pieces may be in the form of longitudinally slitted sleeves which are clipped either directly onto a tension member or onto a pressure element, being provided in the latter case with triangularly profiled end flanges to separate the engaged pressure element from its neighbors on one side of the centerline of the column. Aligned wedge pieces of adjoining armatures may be interconnected by a transverse strap.
    • 用于床垫,座垫等的可张紧的内部加强结构,包括一个或多个细长的拉伸构件,每个细长的拉伸构件横穿相互邻接的压力元件的列以形成可折叠的电枢,包括插入相邻的压力元件之间的若干楔块,以赋予 对电枢的期望曲率。 楔形件可以是纵向切割的套筒的形式,其被直接夹紧到张紧构件或压力元件上,在后一种情况下被设置成具有三角形的端部凸缘,以将接合的压力元件与其邻近的一侧分离 的列的中心线。 邻接的电枢的对准的楔形件可以通过横向带相互连接。
