摘要： A chair located on an aisle of a theatre, arena, stadium or the like, which is easily accessible from a walker or wheelchair. The chair has an armrest proximal to the aisle which pivots in an upwardly manner providing an unobstructed path into the chair. Once the individual is seated, the armrest can be pivoted in a downwardly manner so that the occupant of the chair can use the armrest in comfort.

摘要： A seating assembly, such as for use in auditorium seating, includes a pair of spaced frame assemblies and a seat and back, each of which is mounted between the frame assemblies. The seat assembly is mounted to the frame assemblies by means of an internal pivoting arrangement providing movement of the seat between an occupied position and an unoccupied, storage position in which the seat is substantially vertical. A biasing arrangement, such as a counterweight, moves the seat toward its storage position. The back is mounted between the frame assemblies by a pivoting back mounting arrangement, providing articulating movement of the back according to the position of the sitter's back. A biasing arrangement, such as a torsion spring, is associated with the back mounting arrangement for moving the back toward a storage position when the seat is unoccupied. The storage position of the back is substantially vertical, to provide a thin depth of approximately 13 inches to the seating assembly when the seat and back are both in their storage positions.
摘要翻译：诸如用于礼堂座位的座位组件包括一对间隔开的框架组件和座椅和背部，每个座椅和后部安装在框架组件之间。座椅组件通过内部枢转装置安装到框架组件，该内部枢转装置提供座椅在被占用位置和空闲的存储位置之间的移动，其中座椅基本垂直。诸如配重的偏置装置将座椅朝向其存放位置移动。背部通过枢转的背部安装装置安装在框架组件之间，根据保持者背部的位置提供背部的铰接运动。诸如扭转弹簧的偏置装置与后部安装装置相关联，用于当座椅未被占用时将背部移动到储存位置。背部的存放位置基本上是垂直的，以便当座椅和背部都处于其存放位置时，向座椅组件提供约13英寸的薄的深度。
