1. A seat framework in combination with a bus having a floor therein, comprising:

  • a tubular seat back frame member of a generally inverted-U-shaped configuration including a horizontal frame portion and a pair of vertical lateral frame portions extending vertically from said horizontal frame portion, said tubular seat back frame member extending in a direction transversely of said bus, thus having a forward plane facing to a side forwardly of said bus and a backward plane facing to a side backwardly of said bus;

    a tubular seat cushion frame member including;

    a forward cross frame portion facing to said side forwardly of said bus;

    a pair of horizontal lateral frame portions extending horizontally from said forward cross frame portion; and

    a backward cross frame portion facing to said side backwardly of said bus;

    said pair of vertical lateral frame portions of said tubular seat back frame member being firmly connected with said pair of horizontal lateral frame portions of said tubular seat cushion frame member, respectively;

    whereupon the seat framework has a forward side facing to the side forwardly of the bus and a backward side facing to the side backwardly of the bus;

    a support leg means for supporting said seat cushion frame member thereupon, said support leg means being fixed on said floor of said bus; and

    a reinforcing means fixedly provided between said tubular seat back frame member and said support leg means, said reinforcing means being basically formed from a tubular material in such a manner as to reinforce said tubular seat back frame member and said tubular seat cushion frame member against deformation due to one great load applied toward said forward side of the seat framework and due to another great load applied toward said backward side of the seat framework.
