摘要： A seating system includes seat and back internal support frames disposed within respective foam-filled seat and back cushions which each have an outer fabric cover. The back assembly is provided with a pair of quick-release clip locks, while the seat assembly includes a plurality of support hooks in combination with mounting brackets and locking mechanisms to facilitate quick mounting and removal of the seat from a support frame such as a wheelchair base. The seat and back assemblies are coupled together in a pivoting manner by means of a handle assembly which allows the seat to be compactly folded and easily carried when removed from a support base. The back inner support frame includes upper and lower support subassemblies pivotally coupled by means of a hinge joint which allows for extension of the lumbar region when the upper support subassembly is moved rearwardly to a reclined position. The seat and back support surfaces are contoured for user comfort and support while a lower, aft portion of the back cushion is provided with a plurality of corrugations to facilitate its flexure. The internal support frame includes telescoping members to allow the internal frame to fit a range of user sizes while the hinge joint in the lower portion of the back assembly may: (1) be locked in a fixed orientation; (2) incorporate forward and aft stops to limit pivoting displacement of the upper back; or (3) have a selected neutral position to which the upper back is biased.
摘要翻译：座椅系统包括设置在相应的充满泡沫的座椅和后靠垫中的座椅和后部内部支撑框架，每个椅子和后部衬垫均具有外部织物罩。后组件设置有一对快速释放夹锁，而座椅组件包括与安装支架和锁定机构组合的多个支撑钩，以便于座椅从诸如轮椅的支撑框架的快速安装和移除基础。座椅和后组件通过手柄组件以枢转的方式联接在一起，该手柄组件允许座椅被紧凑地折叠并且当从支撑座移除时容易携带。后部内部支撑框架包括通过铰链接头可枢转地联接的上部和下部支撑子组件，当铰链接头上部支撑组件向后移动到倾斜位置时允许延伸腰部区域。座椅和后支撑表面的轮廓是为了使用者的舒适和支撑，而后垫的下部后部设置有多个波纹以便于其弯曲。内部支撑框架包括伸缩构件，以允许内部框架适应一定范围的使用者尺寸，而后部组件的下部中的铰链接头可以：（1）以固定的方向被锁定; （2）包括前后挡块，以限制上背部的转动位移; 或（3）具有上背部被偏置的选定中性位置。
