  • Patent number: 4278287
    Abstract: A folding seating piece, preferably in the form of a chair (10) includes pivotally interconnected frames (12, 14 and 16) forming a seat, backrest and armrests. A frame member (28) of the seat adjacent each side of the chair includes a snap fastener (40) connected thereto; each of said fasteners including a laterally extending guide section (46) and a downwardly directed clip section (48). The guide section of each clip overlies an adjacent frame member (34) for engaging, and being adapted to move along the adjacent frame member as the chair is being pivoted into its open position. The clip section of each snap fastener generally aligns with an additional frame member (38) of the chair when its respective guide section is closely positioned to the adjacent frame member it overlies and the chair is in its desired opened position.
