Abstract

Attachment of a suspension mat to a tubular seat frame is accomplished by partially or fully forming the tubular frame at the location of the attachment with a concave surface. The suspension mat has a J-clip fastener which conforms to the shape of the formed tube and is fitted around the tube and seated partially into the formed concave area. By forming the tube, and producing a concave surface portion on the tube, the J-clip fastener can be seated on the bent edge of the concave surface portion and prevented from rotating about the tube axis.

Claims

1. A seat assembly comprising:

a support frame having an elongated hollow tubular member with a generally circular cross section having a convex surface, said tubular member having an attaching section along a portion of the length of said elongated tubular member, said attaching section comprising a recess in said tubular member such that in cross section said tubular member has both convex and concave surface portions;

a suspension mat attached to said attaching section of said tubular member; and

a fastener coupled to said suspension mat having a hook configured to engage said attaching section of said tubular member and to engage both said concave surface portion and said convex surface portions of said attaching section of said tubular member.

2. The seat assembly of claim 1 wherein said tubular member has a plurality of said attaching sections and said suspension mat has a plurality of said fasteners.

3. The seat assembly of claim 1 wherein said frame is bent in multiple directions to form a three dimensional body having spaced opposite sides each having one of said attaching sections, said suspension mat being drawn tight between said opposite sides and said suspension mat having one of said fasteners along opposite edges for attaching said suspension mat to said opposite sides of said frame.

4. The seat assembly of claim 1 wherein said fastener is an elongated strip fastener.

5. The seat assembly of claim 1 further comprising a pair of fore and aft slide tracks carrying said frame for fore and aft movement, said slide tracks each having a fixed part for mounting to a support structure and a sliding part which moves fore and aft on said fixed part, said support frame being mounted to said sliding parts for movement therewith.

6. The seat assembly of claim 1 wherein said fastener is sewn to said suspension mat along an edge thereof.

7. The seat assembly of claim 1 wherein said fastener is a plastic molding molded onto an edge of said suspension mat.
