Abstract
A slide track structure for supporting a passenger seat consists of a U-shaped track disposed completely within a square tube supported on the track by balls arranged in the U-track between waved guide strips mounted opposite each other on the track and the square tube and forming a channel receiving the balls. At least one of the guide strips is resiliently supported to bias the square tube so as to cause engagement of the flat adjacent surfaces of the U-track and the square tube when no load is carried by the track. The track is mounted on support bases projecting through slots in the square tube to permit movement of the square tube relative to the U-track.
Claims9
A slide track structure especially for supporting passenger seats in different positions, said slide track structure comprising two tracks movable relative to each other in longitudinal direction and having opposed surfaces;
- guide strips disposed on the surfaces of said tracks facing each other;
- elastomer support means disposed between at least one of said guide strips and the associated track for resiliently supporting said guide strip on said track, said guide strips being waved to define therebetween a passage of essentially circular cross-section, and at least two balls disposed in said passage for supporting one of said tracks on the other, said one track being a square tube and the other being a U-track received within said square tube so as to engage said guide strips, said elastomer support means, said balls and the other U-track enclosed within said square track to prevent rattling when no load is supported by said slide track structure, said square tube having at least one slot formed in its bottom side and said U-track having connected thereto a mounting base, which extends through said slot in said square tube to permit movement of said square tube relative to said U-track when said mounting base is mounted on a support structure.
