Abstract: The present invention provides a seat which is unlikely to cause wrinkles or slack in a surface cover thereof, makes surface cover attachment and detachment simple, and is also capable of withstanding long-term use. To this end, a second fastening part 50 for attachably/detachably connecting a cushion material 2 and a surface cover 4 to one another is formed as a zipper in a seat 1.

Abstract: To make it possible to improve a low-tone reproducing ability with a simple structure in an acoustic device including speakers in a headrest. The acoustic device includes a core material of a closed structure functioning as a core of a headrest main body, acoustic speakers 50, 50 disposed in the core material, and hollow headrest stays 15, 15 that pierce through the core material. The headrest stays 15, 15 circulate the air on the inside of the core material to the outer side via hollow sections.

Abstract: A recessed seam structure for a cover (3) that improves workability when forming a recessed seam (A) and allows frequent attachment and detachment at the recessed seam (A) is provided. In a seat (1) having the recessed seam (A) formed by pulling part of the cover (3) toward a side of a cushion material (2), the recessed seam (A) is provided with an opening and closing fastener (30) configured to couple the cover (3) and the cushion material (2), and the opening and closing fastener (30) includes a first fastener half (31) fixed to a back face of the cover (3) and a second fastener half (32) fixed to the cushion material (2). In such a seat (1), the recessed seam (A) can be formed easily and reliably on the seat (1) by aligning an end of the first fastener half (31) in a longitudinal direction and an end of the second fastener half (32) in the longitudinal direction of the opening and closing fastener (30) and simply sliding a slider (33).

Abstract: There is provided a head rest device 10 that does not impair safety of a seated person even when a secondary battery 35 is accommodated therein. An accommodation space 28 partitioned by a partitioning plate part 25 is provided inside a cushioning core material 12 of a head rest main body, and a secondary battery 35 is accommodated inside the accommodation space 28.

Abstract: To prevent a person from experiencing discomfort when touching portions of a headrest having built-in speakers; to enable the headrest to be formed compactly by arranging the speakers close to the body of the person; and to prevent any decrease in the acoustic pressure and/or acoustic quality of sound from the speakers. Provided are: a plurality of speakers 25a, 25b; fiber pads 15 provided to the front surfaces of the speakers 25a, 25b; a sound-insulating pad 16 provided between the fiber pads 15; and a surface skin 9 for covering the speakers 25a, 25b, the fiber pads 15, and the sound-insulating pad 16, the fiber pads 15 being formed from an elastic material that has a three-dimensional-mesh structure therein, and the sound-insulating pad 16 being formed from an elastic material for minimizing the transmission of sound.

Abstract: To make it possible to provide an acoustic device in a headrest device such that a standard of a shock is satisfied and the performance of the acoustic device can be efficiently exhibited. In the headrest device, a shock resistant surface is formed in a core material of a headrest main body, an opening is formed in the shock resistant surface, and a non-contact type acoustic microphone is disposed on the inner side of the opening.

Abstract: A hooking structure (10) of a seat for supporting a trim cover (7) by hooking the trim cover (7) onto a seat member (3) constituting the seat, the hooking structure (10) comprising: a linear hook member (14) used for hooking, the linear hook member (14) being arranged on a front surface side of the trim cover (7); and an anchoring member (18) which anchors the linear hook member (14) onto the seat member (3), with the linear hook member (14) being inserted in a hooking groove (11) formed in the seat member (3). An insert member (16) to be engaged with the anchoring member (18) is preferably provided inside the seat member (3).

Abstract: The present invention provides a seat which reduces the load applied to a first fastening part, is unlikely to cause wrinkles or slack in a surface cover, and makes surface sheet attachment and detachment simple. To this end, a first fastening part and a second fastening part of a seat are attachable and detachable; hence, it is possible to easily exchange a surface cover according to the season and to clean the surface cover. The second fastening part attachably/detachably connects the surface cover and the rear-surface cover to one another. As a result, the second fastening part appropriately reduces the load directly applied to the first fastening part, making it possible to prevent damage to the first fastening part, and making it unlikely for wrinkles or slack to occur in the surface cover. Furthermore, the second fastening part is the same color and hue at each suspended section; hence, aligning the surface sheet position is easy.

Abstract: Container for accommodating small article(s) comprises: a container body including flange portion wherein connecting slits are formed; and a container lid element including lateral wall region having projected connecting pieces. A trim cover assembly of the seat includes: a peripheral end area or margin defined in a container mounting hole formed in the trim cover assembly; and connecting slits formed in that margin. In assembly, the connecting pieces are inserted through those flanged portion, while simultaneously the margin of trim cover assembly is sandwiched between the flanged portion and lateral wall region. Those free ends are flattened to connecting slits, respectively, so that free ends of the connecting pieces project from the connect together all the container body, container lid element and trim cover assembly. Finally, the trim cover assembly is attached upon a foam padding, with the container body inserted in a recession of the foam padding.
