Patent number: 10576852Abstract: The vehicle seat is structured by covering the pad surface with the surface layer provided with the beading, which prevents the beading formed on the vehicle seat from being rubbed and worn out by clothing of the occupant who is getting on or off the vehicle under pressure applied by the thigh or the back of the occupant, and further prevents dislocation of the beading on the seat under pulling force applied by the thigh of the occupant who is getting on or off the vehicle. The pad has a groove in which the beading is embedded. The beading is embedded in the groove famed in the pad, and the surface layer for enclosing the beading core of the beading is bonded and fixed to the bottom surface of the groove.Type: GrantFiled: December 14, 2015Date of Patent: March 3, 2020Assignee: TACHI-S CO., LTD.Inventors: Ayaru Sasaki, Hideki Kamata, Yasuyuki Ito

Patent number: 10351415Abstract: In order to solve the issue, during recessed-shape molding for vehicle seats, of requiring a suspension step, more work, members for suspension, and increased cost in a method using suspension, a recessed-shape molding method is provided for vehicle seats having a seat frame, a seat pad covering the seat frame, and a trim cover covering the seat pad. The seat pad has a seat pad groove. An adhesive sheet is sewn on to the rear surface of the trim cover by using outer stitching, the trim cover is put on to the seat pad, then a die is pressed on to the outer stitching from the trim cover surface, the trim cover is adhered to the seat pad groove, and a recessed shape is formed. As a result, a vehicle seat having simplified molding steps and effectively reducing costs can be provided, as well as a vehicle seat molding method used for same.Type: GrantFiled: December 9, 2015Date of Patent: July 16, 2019Assignee: TACHI-S CO., LTD.Inventors: Ayaru Sasaki, Hideki Kamata, Yasuyuki Ito, Ukyo Miyazawa

Patent number: 10220740Abstract: In existing manufacturing methods wherein a bonded seat is formed by adhering a surface skin material to a pad made from molded foam, defects may occur from curing of the adhesive, such as reduced flexibility and a poor texture on the seat contact surface. In addition, the manufacturing steps therefor are complicated. In order to solve the above problems, the present invention provides a manufacturing method for a vehicle seat having a molded pad and a trim cover that covers the molded pad. The molded pad has a groove, and an adhesive is applied to the inside of the groove. The trim cover is pressed into the inside of the groove, and a steam nozzle is inserted into the molded pad from the surface of the molded pad opposite from the surface covered by the trim cover. Heat or steam from the steam nozzle melts the adhesive inside the groove so as to adhere the trim cover to the groove.Type: GrantFiled: December 9, 2015Date of Patent: March 5, 2019Assignee: TACHI-S CO., LTD.Inventors: Hideki Kamata, Ayaru Sasaki

Patent number: 5362535Abstract: A location board in a covering member of a vehicle seat, which is used in such a seat assemblage which involves bonding at least two cover sections of a covering member to a cushion member and is of such type that can be teared along the sewn jointed portion of those two cover sections for attaining a resultant seat. The location board is formed with a notched portion laying along an imaginary sewing line. In the seat assemblage, the two cover sections of covering member are sewn to one section of the location board, thus forming a series of sewing holes in the location board. The notched portion is elongated in reference to the sewing holes at such a length that permits a tearing to occur from the notched portion towards the sewing holes in a direction to prevent creation of a pointed projection at the teared edge of residual section of location board in the resultant seat at a stage of tearing off another section of the same location board.Type: GrantFiled: September 29, 1992Date of Patent: November 8, 1994Assignee: Tachi-S Co., Ltd.Inventors: Ayaru Sasaki, Youichiro Haraguchi, Shigeki Kon
