Patent number: 10899308Abstract: Provided is a bag body which has a flatter shape in its expanded state. This bag body has control yarn therein, which controls expansion. The control yarn includes: a first seam which extends from a non-expansion section to another non-expansion section within the bag body; a second seam which is a seam forming the fabric on one surface of the expansion section of the bag body, and is formed by being separated from the fabric on said one surface, threaded through the first seam, and turned back to the fabric on said one surface; and a third seam which is a seam forming the fabric on the other surface of the expansion section of the bag body, and is formed by being separated from the fabric on the other surface, threaded through the first seam, and turned back to the fabric on the other surface.Type: GrantFiled: February 6, 2017Date of Patent: January 26, 2021Assignee: SUMISHO AIRBAG SYSTEMS CO., LTD.Inventors: Masatoshi Yoshida, Teppei Harabayashi

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

Patent number: 9403502Abstract: Provided is an airbag having a function for controlling bag-section expansion while also retaining air-tightness, by reducing the concentration of stress applied to restriction threads during deployment. Provided is a bag body having, in the interior, restriction threads for restricting expansion, wherein the restriction threads comprise: first yarn extending in the interior of the bag body from a non-expanding section to a different non-expanding section; second yarn which forms a base fabric of one side of an expanding section of the bag body and which is separated from the one side and is caught on the first yarn, or is woven with the first yarn to constitute a structure, again returning to the base fabric of the one side; and third yarn which forms a base fabric of the other side of the expanding section of the bag body and which is separated from the other side and is caught on the first yarn, or is woven with the first yarn to constitute a structure, again returning to the base fabric of the other side.Type: GrantFiled: February 27, 2013Date of Patent: August 2, 2016Assignee: SUMISHO AIRBAG SYSTEMS CO., LTD.Inventors: Takeshi Tanaka, Masatoshi Yoshida, Teppei Harabayashi
