Definitions

  • This invention relates to adjustable chairs and it has for its object the construction of an arm chair (a) which is built up of a plurality of separate sections, primarily designed for export purposes, adapted to be assembled together and maintained in position by spacing members, (1)) which will when assembled and fully upholstered have the appearance of an ordinary padded easy chair and (c) which will enable same to be used so that the user may sit in an approximately upright position or in a semi-reclining position, or in one or more intermediate positions, the change in position being effected by the operation of one or more control devices without the user rising from the chair.
  • the chair comprises a framework embodying two side frames constituting the arms and sides of the chair, means for securing said side frames in rigid relationship, a back frame and a seat frame hinged together, the back frame being pivoted adjacent the lower end thereof in the side frames, the seat frame being pivoted adjacent its front end in said side frames, means permitting the pivot members of both back and seat frames to be raised or lowered and means for effecting and controlling the movements of said back and seat frames.
  • FIG. 1 is a perspective view of the frame- Work of the chair in assembled relationship.
  • Figure 2 is a sectional side elevation approximately on the line II-II of Figure 3.
  • Figure 2A is a sectional side elevation of the front part of one of the side arms.
  • Figure 3 is a vertical transverse section on line III-III of Figure 2.
  • Figure 4 is a vertical transverse section on line IV-IV of Figure 2.
