Abstract: A vehicle seat includes a seat pad and a seat cover including a first part and a second part. The seat cover is provided with: a sewing line that sews the first part and the second part together; and an outline stitch that extends in parallel to the sewing line and that is located on one side of the sewing line. A belt-shaped plate is sewn to a first seam allowance and a first main body of the first part by the outline stitch in a position on an end side of the first seam allowance relative to the sewing line. The seat pad is covered with the seat cover in a state where the belt-shaped plate extends beyond the sewing line toward the second part and where the belt-shaped plate presses a second seam allowance to abut against a second main body of the second part.

Abstract: The present disclosure relates to a vehicle seat having a seat pad and a planar seat cover. The seat cover may include a plurality of the skin materials and at least one seam allowance formed by sewing the adjacent skin materials each other. The seam allowance includes end portions of the adjacent skin materials projecting from a back surface of the seat cover. The seat pad may include a plurality of recessed grooves and an intersecting area of the grooves. The skin material may include a high-rigidity portion disposed at the intersecting area and configured to cover at least one of the corners formed at the intersecting area. The high-rigidity portion may include a planer overlapping portion laid over a back surface of the skin material.

Abstract: A conveyance seat may include a seat pad, a first recess and a second recess formed in the seat pad. The first recess may have a pad-side engaging member disposed therein. The second recess may have no pad-side engaging member disposed therein. The conveyance seat may include a seat cover configured to cover the seat pad, the seat cover including a plurality of cover pieces, a first stitched portion and a second stitched portion projecting from the seat cover. At the first and second stitched portions, adjacent cover pieces may meet. The first stitched portion may have a cover-side engaging member configured to engage the pad-side engaging member. The second stitched portion may have no cover-side engaging member and may intersect with the first stitched portion at an intersection point. The conveyance seat may include a reinforcement member attached to the second stitched portion and bestriding the intersection point.

Abstract: A vehicle seat including: a seat pad including: a first surface portion; a second surface portion; and a peripheral edge portion forming a boundary between the first and second surface portions, and a seat cover including: a first cover portion; a second cover portion; and a sewn portion in which a first seam allowance of the first cover portion and a second seam allowance of the second cover portion are overlapped in a state of being turned back inwardly and are sewn together, the sewn portion being arranged along the peripheral edge portion, and a portion of the sewn portion arranged along the peripheral edge portion is formed of the first seam allowance and the second seam allowance which is shorter than the first seam allowance, and the first seam allowance is tilted toward in a manner of facing either the first surface portion or the second surface portion.

Abstract: An interior equipment including: a sewn portion where seam allowances of first and second covers are overlapped in a state where front surface thereof face each other; a regulating member which regulates a falling direction of a leg portion of a piping, wherein the regulating member is attached to a second cover side of the sewn portion and protrudes from an end of the sewn portion, and wherein, in a state of being pressed against a corner portion of a pad member, the regulating member falls toward the first cover together with the leg portion of the piping which is co-sewn to the sewn portion, and thereby a portion of the first cover which is folded back at a seam is arranged to be overlapped with the sewn portion on the corner portion in a state of being raised by a head portion of the piping.

Abstract: A vehicle seat including: a seat pad; and a seat cover including: a first cover piece and a second cover piece which are arranged adjacent to each other; and a sewn portion, wherein the first cover piece includes a general portion which forms a design surface of the seat and a thin end portion which projects from an edge of the general portion and has a thickness smaller than a thickness of the general portion, and wherein in the sewn portion in a tilted state, the thin end portion is bent back towards a back side of the general portion so as to form a lateral U shape, and a part of the thin end portion which is arranged at a back side thereof serves as a seam allowance of the first cover piece and is overlapped with and sewn to a seam allowance of the second cover piece.

Abstract: An interpolation device (4) includes a band extraction high-pass filter (11) for extracting a frequency component of a predetermined lower limit frequency or above from reproduction data obtained by digitizing an audio waveform signal; a multiplier (13) for frequency-shifting the frequency component extracted by the band extraction high-pass filter (11); lower side wave band suppression high-pass filter (14) suppressing the frequency component of the lower side wave band in the frequency component subjected to frequency shift by the multiplier (13); and an adder (17) for adding the frequency component after suppression by the lower side wave band suppression high-pass filter (14). It is possible to reduce the processing load.
