Definitions

  • a pressure spring means 20, FIG. 3, in the form of a helical coil spring is located between the seat frame 7 and the base plate 1 to retard downward movements of the seat.
  • the linkage system comprises a forward pair of parallel spaced link arms 3a, 3b which at their lower ends are pivotable about a first common pivot axis 3c. There is also a rearward pair of parallel spaced link arms 3d, 3e, which at their lower ends are pivotable about a second common pivot axis 3f.
  • each of the two link arms at one side of the seat pivotally support a buffer arm extending downwardly and having its free lower end portion resting on an elastic buffer member, the free ends of the two buffer arms being located adjacent each other and subjected to the action of common adjusting means provided to enable a desired initial pressure of the two buffer arms on the elastic buffer member.
