  • Patent number: 6547322
    Abstract: A chair with four sets of leg tubes(22) consisting of two leg tubes(22) attached at their centers in an X position which fold into a collapsed position with leg tubes(22) nearly parallel to each other. Seat tubes(24), and back tubes(44) are pivotally attached to the upper ends of leg tubes(22) at the rear of the chair. Seat tubes(24) are connected to leg tubes(22) at the front of the chair by seat clips(30). This configuration of the chair in the open position, provides a stable structure for the attachment of a seat cover(42) and for the attachment of a mechanism for reclining back tubes(24) and back cover(11). Arm braces(18) extending from the top of leg tubes(22) at the rear of the chair, and connected to vertical tubes(14) extending from near the center of seat tubes(24) support arm tubes(8), which are attached to back tubes(44). Back tubes (44) recline by moving arm tubes(8) to different positions in slots in arm plates(12) attached near the front of arm tubes(8).
