ABSTRACT:
The folding chair (10) includes V-shaped main support frame (12) with an apex (28) and two legs (22 and 24) with free ends. A V-shaped seat support frame (14) has an apex (40) and two arms (34 and 36) with free ends. The V-shaped seat support frame (14) is pivotally attached to the main support frame (12) by pivot pins (48 and 50) which allow pivotal movement between a position in which both V-shaped frames (12 and 14) are in a common plane and a position in which the seat support frame (14) is in a plane that is generally perpendicular to the plane through the main support frame (12). A third leg (16) is pivotally attached to the V-shaped main support frame (12) near its apex. The third leg (16) is connected to the apex portion (40) of the V-shaped seat support frame (14) by a pin member (66) and holds the seat support frame in a fixed position relative to the V-shaped main support frame. The pin (66) is removed to allow both V-shaped support frames (12 and 14) and the third leg (16) to fold flat and into a common plane. A back rest (20) is secured to the apex (40) of the V-shaped main support frame (12). A support seat (18) is attached to the free ends of the arms (34 and 36). The pivot pins (48 and 50) pass through conical bores (52 and 54). Shoulder straps (86 and 88) are provided for carrying the chair (10). Hooks (94) can be provided for attaching a backpack to the chair and carrying brackets (96) can be provided for attaching other equipment to the chair.
