Patent number: 10369909Abstract: A surface fastener formed of a synthetic resin and in which a base with a 0.1 to 0.9 mm thickness and engagement element groups including engagement elements with a 0.2 to 0.8 mm protrusion height are integrally molded, and engagement element rows are composed of the plural engagement elements arranged in a row direction and each protruding independently. A cushioning member is covered with a covering member via the surface fastener. A resistance value of the surface fastener by itself as measured by a handle-o-meter method conforming to the JIS L 1096 E method is 80 to 150 g, whereas a load-deflection characteristic when a pressure is applied to an overlapping portion of the stacked surface fastener and cushioning member by a pressure plate with a 30 mm diameter approximates a similarly measured load-deflection characteristic of the cushioning member by itself.Type: GrantFiled: February 25, 2015Date of Patent: August 6, 2019Assignees: DELTA TOOLING CO., LTD., KURARAY FASTENING CO., LTD.Inventors: Etsunori Fujita, Yumi Ogura, Seiji Kawasaki, Shigeki Wagata, Yukitoshi Higashinaka, Satoru Ono, Tooru Tanokura

Patent number: 10227229Abstract: A headrest in which a pad layer is integrally formed, including a portion with a narrow gap, between a mechanism having various types of incorporated functions and a skin member. A shock absorbing member that is an injection-passage-forming member having a foaming raw material injection passage formed so as to run substantially along a direction that is the vertical direction of the headrest in orientation of when a seat is attached, is set in the inside of a skin member, and a foaming raw material for forming the pad layer is injected through the foaming raw material injection passage. The configuration preferably causes the foaming raw material to spread by the foaming start time, as the foaming raw material spreads to the outer side of the headrest, that is, to the inner surface of the skin member, where the pad layer is required to be formed.Type: GrantFiled: January 22, 2016Date of Patent: March 12, 2019Assignee: Delta Tooling Co., Ltd.Inventors: Etsunori Fujita, Kazuhiro Takenaka, Kazunari Yasui, Shigeki Wagata

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. Ltd.Inventors: Etsunori Fujita, Yumi Ogura, Seiji Kawasaki, Shigeki Wagata, Yoshimi Enoki

Patent number: 9144402Abstract: A technology to grasp a state of a human being more accurately is provided. The technology is provided with means for acquiring a time-series waveform of a frequency from a time-series waveform of a biological signal sampled from the upper body of a human being and for further acquiring a time-series waveform of frequency slope and a time-series waveform of frequency fluctuation and for applying frequency analysis to them. In the frequency analysis, a power spectrum of each frequency corresponding to a functional adjustment signal, a fatigue reception signal, and an activity adjustment signal, respectively, determined in advance is acquired. Then, a state of a human being is determined from a time-series change of each power spectrum.Type: GrantFiled: January 31, 2011Date of Patent: September 29, 2015Assignee: Delta Tooling Co., Ltd.Inventors: Etsunori Fujita, Yumi Ogura, Shinichiro Maeda, Naoki Ochiai, Shigeki Wagata

Patent number: 8919887Abstract: To achieve weight reduction while providing elasticity sufficient in a cushioning member for a vehicle seat, an elastic member made of expanded resin beads includes an elastic covering material having stretching properties stuck to an outer face of an expanded bead body. Therefore, when the elastic member made of expanded resin beads is bent or compressed, the respective beads themselves configuring the expanded bead body are elastically deformed according to stretching or compressing of the elastic covering material, and since the elastic deformation is not such deformation that a gap between beads of the expanded bead body largely expands, a crack occurring between beads or permanent deformation does not occur so that bending or compressing becomes possible. Accordingly, the elastic member made of expanded resin beads is suitable as a cushioning member utilizing an elastic recovering force in a bending direction and a thickness direction thereof.Type: GrantFiled: May 22, 2009Date of Patent: December 30, 2014Assignee: Delta Tooling Co., Ltd.Inventors: Etsunori Fujita, Yumi Ogura, Soichi Makita, Shigeki Wagata, Seiji Kawasaki, Yuji Hattori

Publication number: 20030234476Abstract: A magnetic spring device and a vibration damping apparatus, which are simpler and cheaper to manufacture, are disclosed. The magnetic spring device includes a plurality of stationary magnets, which are spaced apart to define a space between them, and a magnetic movable element, which is fit in the space. The magnetic poles of the stationary magnets are opposite to each other. The movable element is moved by the magnetic force generated by the stationary magnets in a parallel direction with the magnetic field. The properly positioned stationary magnets and movable element form a magnetic spring device, which together with additional properly positioned magnets alone may be used as a vibration damping apparatus. Also, when the magnetic spring device is combined with a cushioning member such as a metal spring, rubber or the like to form a vibration damping apparatus, the total elastic constant of the vibration damping apparatus may be near zero.Type: ApplicationFiled: June 12, 2003Publication date: December 25, 2003Applicant: Delta Tooling Co., Ltd.Inventors: Yoshimi Enoki, Shigeki Wagata, Hiroki Oshimo, Etsunori Fujita, Hiroki Honda, Hideyuki Yamane
