ABSTRACT:
Disclosed is a track fitting for an airplane seat leg which has a unitary bearing section and wall element that carries the pin holding the seat leg in position. The bearing section comprises an opening defined by two truncated conical walls with the abutting truncated sections providing a bearing site. The open ends of the opening are surrounded by segmented spherical bearing surfaces which carry caps having conforming internal, spherical bearing surfaces. The pin passes through the assembly of caps and bearing section to secure the leg in position. A plastic, box-like anti-rattle device to prevent rattling is mounted to the rear of the track fitting and bears against the top of a track receiving the fitting.
