Patent number: 9868412Abstract: Provided is an air-bag integrally formed by hollow weaving and including a control seam for restricting expansion. The control seam is extended from the base fabric on one surface of an expansion portion of the air-bag to the base fabric on another surface, and the base fabrics are joined. The control seam extending from the base fabric on the one surface to the base fabric on the other surface, and the control seam extending symmetrically from the base fabric on the other surface to the base fabric on the one surface constitute a pair of control seams One or more pairs of the restriction yarns are arranged in a block shape, forming a restriction yarn block. Adjacent restriction yarn blocks are disposed in a parallelly staggered manner with respect to the direction in which the restriction yarns extend.Type: GrantFiled: July 8, 2014Date of Patent: January 16, 2018Assignee: SUMISHO AIRBAG SYSTEMS CO., LTD.Inventors: Masatoshi Yoshida, Tadashi Takemoto

Patent number: 9863069Abstract: A junction band with high tensile strength in order to suppress rupture of a ground fabric from the junction band. Provided is a hollow-weave base fabric that includes a hollow-weave section (111) with a dual layer structure containing a first fabric layer and a second fabric layer, and a junction band (112) formed continuously from threads which form the hollow-weave section. The junction band comprises a first junction structure section (121), in which a structure of two layers is formed by the alternating positional relationship of a first continuation thread that extends from the first fabric layer of the hollow-weave section to the first junction structure section and a second continuation thread that extends from the second fabric layer of the hollow-weave section to the first junction structure section.Type: GrantFiled: March 17, 2015Date of Patent: January 9, 2018Assignee: SUMISHO AIRBAG SYSTEMS CO., LTD.Inventor: Teppei Harabayashi
