ABSTRACT:
A lightweight fabric structure having a plurality of arches, and more particularly, a pavilion type tent structure having arches to define the periphery of the structure with a flexible fabric membrane in tension between the arches. Adjustable length tension bars are placed between adjacent arches to maintain tension and hold the arches upright. Adjacent segments of the membrane are sewn back-to-back to provide a reverse curve seam to increase the usable space inside the fabric structure without the use of a center support or tension lines.
