Publication number: 20180360315Abstract: The present invention uses a time-series waveform of biosignal information collected from the back of a person and including biological sound and vibration (back body surface pulse wave). The back body surface pulse wave is pressure vibration arising from cardiac and aortic motions, and includes ventricular systolic and diastolic information and information on vascular wall elasticity which serves as an auxiliary pump for the circulation, and is considered as a vibration system including both the damping of viscous damping friction and the damping of solid friction. The back body surface pulse wave fluctuates according to a flow rate (stroke volume) of blood pumped out from the heart, and the fluctuation of this flow rate is reflected in the amplitude of the time-series waveform of the back body surface pulse wave.Type: ApplicationFiled: December 12, 2016Publication date: December 20, 2018Applicant: DELTA KOGYO CO., LTD.Inventors: Etsunori FUJITA, Yumi OGURA, Ryuichi UCHIKAWA, Kanako NAKASHIMA

Patent number: 10136850Abstract: A biological body state estimation device configured such that a homeostatic function level is sorted and acquired in plural stages by using a biological signal obtained from an upper body of a person and each stage of the homeostatic function level is plotted in time series in accordance with a time axis indicated on the lateral axis and displayed as a graph by a display. A highest part on the vertical axis of the graph can be displayed as a highly active state and a lowest part as a function decline state. Therefore, a state of fluctuation due to autonomous nerves as an attempt to maintain homeostasis, progress of a feeling of fatigue, and a state stimulated by activation of the brain can be captured as a periodic function. Moreover, a sleep prediction phenomenon can be captured.Type: GrantFiled: October 14, 2010Date of Patent: November 27, 2018Assignee: Delta Tooling Co., Ltd.Inventors: Etsunori Fujita, Yumi Ogura, Shinichiro Maeda, Naoki Ochiai

Patent number: 10118513Abstract: A seat structure. A reinforcing structure in a substantially rectangular frame shape is set in an area where cushion-part side frames and back-part side frames are coupled to each other via reclining mechanism parts, from vicinities of rear portions of the cushion-part side frames up to vicinities of lower portions of the back-part side frames. The reinforcing structure increases unity of a cushion frame and a back frame, and when a load is applied to the back frame due to an impact at the time of a rear-end collision or the like, the load acts as a force deforming mainly the cushion frame via the reinforcing structure, and when the body of a seated person thereafter moves rearward, the load acts as a force deforming mainly the back frame, making it possible to use not only strength of the back frame but also strength of the cushion frame.Type: GrantFiled: May 11, 2015Date of Patent: November 6, 2018Assignee: Delta Tooling Co., Ltd.Inventors: Etsunori Fujita, Yumi Ogura, Masahiro Kuromoto

Patent number: 10118323Abstract: To obtain an integrated foam-molded product whose manufacturing cost is reduced and which makes an effective use of a property of an integration target. Foaming heat generated at the time of the foaming of a polyurethane foam raw material, whose influence has been conventionally prevented by contriving a special measure, is positively used. The integration target is influenced by foaming heat generated at the time of the foaming of the polyurethane foam raw material in a mold, to thermally deform into a desired shape along a mold shape. Consequently, it is possible to mold the integration target into an arbitrary shape in a step of integrating the integration target with a polyurethane foam layer in the mold by integrated foaming, and therefore, there is no need to work the integration target to a state closer to a final shape in a step before it is disposed in the mold, which can simplify manufacturing steps and reduce manufacturing cost.Type: GrantFiled: September 8, 2014Date of Patent: November 6, 2018Assignee: Delta Kogyo Co.

Patent number: 9826295Abstract: To enable an output sound of a speaker unit to be output as a surface sound source in a limited space. A three-dimensional knitted fabric is provided at a position substantially facing speaker units while being given tension in a surface direction. Since the tension is applied, a pair of ground knitted fabrics constituting the three-dimensional knitted fabric and a connecting yarn extending back and forth between the ground knitted fabrics vibrate due to their elastic action. In particular, string vibration is generated in the connecting yarn. Due to this vibration, output sounds of the speaker units are propagated in the surface direction of the three-dimensional knitted fabric, and as a result, the three-dimensional knitted fabric propagates and radiates acoustic waves of a surface sound source.Type: GrantFiled: November 11, 2014Date of Patent: November 21, 2017Assignee: DELTA TOOLING CO., LTD.Inventors: Etsunori Fujita, Yumi Ogura, Seiji Kawasaki, Shinichiro Maeda, Kosuke Aoi, Tatsuya Motoie

Patent number: 9738196Abstract: A base net for a back is formed from a three-dimensional stereoscopic knit, and has a configuration in which seams for bringing a pair of ground knitted fabrics thereof to close to each other in a thickness direction are partially provided, predetermined preliminary compression is applied in the thickness direction by the seams, and thereby residual stress is generated in a surface direction (stretching direction). Therefore, stiffness is partially increased by partial improvement in residual stress, and consequently a human body with extreme roughness is supported by nearly uniform pressure. Thus, in spite of a simple configuration in which the seams are provided in desired regions, posture supportiveness and body pressure dispersiveness can be improved. Further, by arbitrarily adjusting the formation positions of the seams, the pressure distribution is adjusted, thereby making it possible to easily control the vibration mode to desired setting, and easily improve vibration absorbency.Type: GrantFiled: November 23, 2012Date of Patent: August 22, 2017Assignee: Delta Tooling Co., Ltd.Inventors: Yumi Ogura, Etsunori Fujita, Seiji Kawasaki, Shogo Inoue, Yuki Arita, Eiji Sugimoto
