摘要： A spring seat for accommodating the depending ischial tuberosities and to reduce the load on them by supporting the ischial tuberosities at a lower level than the supporting means under the buttocks of a seated occupant which take on a significant portion of the load.

摘要： The box spring and box spring structure include a versatile frame made at appreciably lesser expense than presently known frames of equal rigidity and light weight. End rails of rectangular cross section carry no springs and are arranged completely underneath and overlap the side rails at the frame corners. All the rails have upper surfaces planar throughout their widths, those of the end rails being in secured engagement with the lower wide faces of the side rails at the frame corners to dispense with braces. The cross slats are parallel to each other and spaced any desired distances apart, equal or unequal. The end slats which carry the end rows of springs are arranged in close proximity to the respective end rails and are spaced above the end rails while extending inwardly enough in width to locate said spring rows in the proper position for upholstering. However, each end slat is securely connected to the end rail adjacent thereto by a longitudinal brace inserted between said end rail and said end slat and constituting the end part of the box spring frame. The brace, end rail and slat cooperate to form a self- reinforcing and self supporting structural unit, the members of which mutually transfer stresses between them. The brace so connected is intended to change the nature of the stresses to which the end parts of box springs have heretofore been subjected. The end portion of the box spring consequently is made capable of supporting unusually heavy loads concentrated on relatively small areas of said end portion. The frame is assembled upside down without rehandling and then righted if the springs have previously been attached to the slats to form the box spring structure or for the attachment of springs if needed and final upholstering.
摘要翻译： 盒弹簧和箱体弹簧结构包括一个多功能框架，其成本比目前已知的相当刚度和重量轻的框架成本低得多。 矩形截面的导轨没有弹簧，并且完全安置在下面，并且在框架角处与侧轨重叠。 所有的导轨在整个宽度上具有平坦的上表面，端轨的边缘在框架角处与侧轨的下宽面紧固接合以省去支架。 交叉板条彼此平行并且间隔任何期望的距离，相等或不相等。 承载弹簧端排的端板被布置成紧邻相应的端轨，并且在端部轨道上方间隔开，同时向内延伸到足够宽的宽度以将所述弹簧排定位在用于装饰的适当位置。 然而，每个端部板条通过插入在所述端部导轨和所述端部板条之间并构成箱形弹簧框架的端部的纵向支架牢固地连接到与其相邻的端部导轨。 支架，端轨和板条配合形成一个自加强和自支撑的结构单元，其构件在它们之间相互转移应力。 如此连接的支架旨在改变盒弹簧的端部部件迄今为止受到的应力的性质。 因此，盒弹簧的端部能够支撑集中在所述端部的相对小的区域上的异常重的负载。 如果弹簧已经连接到板条上以形成箱形弹簧结构，或者如果需要和最终的装饰，则可以将框架倒置而不进行重新处理，然后如果弹簧已经连接到板条上，则可以弹簧附接。

摘要： A prestressed sinuous spring for furniture springing in which the upwardly spanned are or contour is loaded and depressed to a modified depth and contour by incorporating and selectively positioning a reinforcing link with the prestressed sinuous spring to resist tension and bending forces to which the prestressed sinuous spring is subjected upon loading between the ends thereof.

摘要： A chair having a seat and a seat back with said seat back having spaced-apart upright members to accommodate the back of a chair occupant in which spaced springy support means are provided in selected regions against which the chair occupant contacts to urge the rib cage and chest outwardly and urge the lumbar vertebral arch rearward, to induce minimal stress in the seated spine by reducing its curvatures.
