Abstract: A fastener for an airbag cover, the fastener comprising first and second stringer tapes which are fixed to edges of an opening in the airbag cover. The stringer tapes each have a row of coupling elements mounted thereon, and these link together to connect the stringer tapes. The connection is strong within an area of coupling elements which have been connected, but is easily disengaged from the ends of a region of connected coupling elements. The fastener comprises holding means which hold the tapes together at a predetermined position in the middle region of the fastener. The holding means will release or displace under the force of the airbag expanding. When the airbag expands, e.g. during a car crash, the holding means allows the coupling elements to open, thus opening the fastener and allowing the airbag to expand outside the airbag cover.

Abstract: In a fastening device with tape, made of synthetic resin, the tape is composed of a warp knitting structure including an attachment area composed of one or more wales disposed at the right and left edge portions in a width direction of the tape, and a fastener-molding area composed of plural wales in a center portion in the width direction of the tape. The warp knitted tape is entirely composed of a knitting structure by tangling of two needle stitch yarns and weft in-laid yarns. A chain stitch yarn is further knitted into the attachment area so as to suppress the stretching property an stabilize dimensional form in the warp direction of the attachment area. In the fastener-molding area, a predetermined stretching property in the warp direction and some extent of stability in dimensional form are secured. The fastening device can be adapted well to an attachment object such as clothes having a stretching property and may be engaged or disengaged securely and accurately.

Abstract: A tape of the fastening device made of synthetic resin is composed of an attachment area formed of one or more wales disposed at right and left edge portions of the tape in the width direction thereof and a fastener-molding area formed of plural wales in a center portion in the width direction. The warp knitted tape is entirely composed of a knitting structure formed by tangling of tricot stitch yarns and single cord stitch yarns, and chain stitch yarns are further knitted in the fastener-molding area so as to suppress stretching property in a warp direction of the area to a maximum extent and ensure a dimensional stability. The attachment area is composed of a knitting structure having required stretching property in its warp direction and some extent of stability in the dimensional form. Therefore, the fastening device with tape can be sewed to and along a curved line easily and can be adapted to an attachment object having stretching property well.

Abstract: A fastener with tape has fastening members of synthetic resin molded integrally and firmly on front and rear surfaces of the tape so as to enclose an entire peripheral portion of a mounting hole of the tape having at least a mounting hole. The fastening members are made of synthetic resin material to which fine inorganic filler is added. The stiffness and the elasticity of the fastening members change depending on the kind and the addition amount of the inorganic filler.

The female button has at least one mold hole extending in a front and back direction of the tape, and at least one portion of the tape extends to an inside of the female button across the mold hole. At least one cut-out recessed in a diameter direction of the female button is defined in a portion of an inner peripheral engaging face of the engaging opening, and a gate burr is formed at a bottom face of the cut-out.

Abstract: A multiplicity of knitting needles and one or more knitting needles are slid vertically along first and second needle beds, respectively, which are disposed in a back-to-back relationship with and spaced a predetermined distance from each other. The second needle bed extends along only one end portion of the first needle bed. And at the same time, a predetermined number of knitting yarn guides are swung and shogged. During that time, a monofilament bending means disposed near one end of the first needle bed reciprocates along the upper space between the first and second needle beds at an underlapping position to continuously form individual fastener elements by bending the monofilament and to knit the formed fastener elements successively in a warp-knit fastener tape by the back-to-back needles in the first and second needle beds simultaneously with the knitting of the tape.

Abstract: In an automatic lock slider for a slide fastener having element rows on its back side, a resilient member having a locking pawl engageable and disengageable with the element rows from the back side is actuated by one end of a pivotal bat pivotable about a pivot, the resilient member being in the form of a small-width metallic leaf spring having a predetermined length and bent in a desired shape. The resilient member keeps adequate resilience for a long period and secures more reliable resilient deformation and restoration compared to a mere leaf spring, so that the locking pawl can come into and out of engagement with the element rows smoothly and reliably, depending on whether or not a pull tab is pulled.
