Description

本発明は、車両用シートに関し、更に詳しくは、スピーカ装置が埋設されたシートバックを有する車両用シートに関する。   The present invention relates to a vehicle seat, and more particularly to a vehicle seat having a seat back in which a speaker device is embedded.

通常、自動車の室内に設けられるスピーカ装置は、音響効果及びレイアウトの観点から、車体側壁やドアの内面側に配設されている。   Usually, the speaker device provided in the interior of an automobile is disposed on the side wall of the vehicle body or the inner surface of the door from the viewpoint of acoustic effect and layout.

しかし、前記スピーカ装置からの音声は遮られやすいため、シートに着座した乗員にまで伝達されにくく、また、積載される荷物の配置によっては、スピーカ装置から発せられる音声が反響または撹乱されて優れた再生音が聴取しにくいという問題があった。このため、近年では、シートバックにスピーカ装置を埋設した音響シートが開発されている（例えば、特許文献１参照）。   However, since the sound from the speaker device is easily blocked, it is difficult to be transmitted to the occupant seated on the seat, and the sound emitted from the speaker device is reverberated or disturbed depending on the arrangement of the loaded luggage. There was a problem that it was difficult to hear the reproduced sound. For this reason, in recent years, an acoustic sheet in which a speaker device is embedded in a seat back has been developed (see, for example, Patent Document 1).

この音響シートにおいては、シートバックの上部に凹部を設け、該凹部にハウジングとスピーカ本体を埋設し、このハウジングの上部からスピーカグリルを取り付けている。
実開平５−４９４７２号公報 In this acoustic sheet, a recess is provided in the upper part of the seat back, a housing and a speaker main body are embedded in the recess, and a speaker grille is attached from the upper part of the housing.

It is formed and is configured to be stretchable in the thickness direction. A recess 41 from which the surface layer portion 11 and the seat back pad 35 are removed is provided at the upper end of the seat back 5, and a speaker housing 29 is embedded in the recess 41. The speaker device 13 includes a housing 29 embedded in a recess 41 of the seat back 5 and a speaker body 43 provided inside the housing 29. A bottom surface 45 of the housing 29 is disposed in contact with a seat frame (not shown), and a speaker body 43 is attached from the inner side of the housing 29 to the back surface side of the top surface. A locking hole 33 is formed in the upper surface, and the locking piece 25 of the speaker grille 15 is inserted into the locking hole 33, and the claw portion 27 at the tip thereof is locked in the locking hole 33. Yes. Further, the upper surface (front surface) 47 of the housing 29 is arranged on the inner side, that is, the lower side of the upper surface (front surface) 49 of the seat back pad 35, and the difference in height is indicated by h.

そして、スピーカグリル１５の外周部２１の端縁２３は、シートバック５の表層部１１の一般面よりもシートバック５の内方側、即ち下方側に配置されている。図３では、スピーカグリル１５の外周部２１の端縁２３とシートバック５の表層部１１の一般面との高さの差違がｄで示されている。   And the edge 23 of the outer peripheral part 21 of the speaker grill 15 is arrange | positioned rather than the general surface of the surface layer part 11 of the seat back 5, the inner side of the seat back 5, ie, the downward side. In FIG. 3, the difference in height between the edge 23 of the outer peripheral portion 21 of the speaker grill 15 and the general surface of the surface layer portion 11 of the seat back 5 is indicated by d.

次いで、スピーカグリル１５をハウジング２９に組み付ける手順について簡単に説明する。   Next, a procedure for assembling the speaker grill 15 to the housing 29 will be briefly described.

まず、図４に示すように、シートバック５の左右両側の上端部には、凹部４１が設けられており、該凹部４１にはハウジング２９が埋設されている。また、凹部４１に対応する表層部１１は矩形状に切り欠かれた開口部５１に形成されており、前述したように、該開口部５１に対応するハウジング２９の上面４７には、係止孔３３が穿設されている。この開口部５１の上方からスピーカグリル１５を下降させ、係止片２５をハウジング２９の係止孔３３に挿通させて爪部２７を係止孔３３に係止させる。   First, as shown in FIG. 4, recesses 41 are provided at upper left and right ends of the seat back 5, and a housing 29 is embedded in the recesses 41. Further, the surface layer portion 11 corresponding to the concave portion 41 is formed in the opening portion 51 cut out in a rectangular shape, and as described above, the upper surface 47 of the housing 29 corresponding to the opening portion 51 has a locking hole. 33 is drilled. The speaker grille 15 is lowered from above the opening 51, the locking piece 25 is inserted into the locking hole 33 of the housing 29, and the claw portion 27 is locked to the locking hole 33.

これにより、図５に示すように、スピーカグリル１５の外周部２１の裏面３１とハウジング２９の上面４７とによって、表層部１１は上下から挟持される。ここで、表層部１１のウレタン樹脂３９は厚さ方向に縮むため、この挟持された表層部１１の厚みは、例えばシートバックパッド３５の上部に配置された一般面の表層部１１の厚みよりも薄くなっている。また、スピーカグリル１５の外周部２１の端縁２３は表層部１１の表皮３７に密着しており、隙間がない状態になっている。   As a result, as shown in FIG. 5, the surface layer portion 11 is sandwiched from above and below by the back surface 31 of the outer peripheral portion 21 of the speaker grille 15 and the upper surface 47 of the housing 29. Here, since the urethane resin 39 of the surface layer portion 11 shrinks in the thickness direction, the thickness of the sandwiched surface layer portion 11 is, for example, larger than the thickness of the surface layer portion 11 of the general surface disposed on the upper portion of the seat back pad 35. It is getting thinner. Moreover, the edge 23 of the outer peripheral part 21 of the speaker grille 15 is in close contact with the skin 37 of the surface layer part 11, and there is no gap.

以下に、本発明の実施形態による作用効果について説明する。   Below, the effect by embodiment of this invention is demonstrated.

外表面が表層部１１で覆われたシートバック５の左右両側の上端部に凹部４１を設け、該凹部４１にスピーカ装置１３を収容すると共に、凹部４１の表面側をスピーカグリル１５によって覆った車両用シートにおいて、前記スピーカグリル１５をシートバック５に押しつけた状態で取り付けることにより、スピーカグリル１５の外周部２１の端縁２３を、シートバック５の表層部１１の一般面よりも距離ｄ分だけ下方に配置させているため、これらの間にシートベルト９が入り込むことがない。従って、シートベルト９を脱着する際に、該シートベルト９やスピーカ装置１３のハウジング２９等に傷が付くおそれがなくなる。   A vehicle in which recesses 41 are provided in upper left and right upper ends of the seat back 5 whose outer surface is covered with the surface layer portion 11, the speaker device 13 is accommodated in the recesses 41, and the surface side of the recess 41 is covered by the speaker grille 15. When the speaker grille 15 is attached to the seat back 5 while being pressed against the seat back 5, the edge 23 of the outer peripheral portion 21 of the speaker grill 15 is a distance d from the general surface of the surface layer portion 11 of the seat back 5. Since it is arranged below, the seat belt 9 does not enter between them. Therefore, there is no possibility that the seat belt 9 or the housing 29 of the speaker device 13 will be damaged when the seat belt 9 is detached.

また、前記スピーカ装置１３を、凹部４１に埋設されたスピーカ用のハウジング２９と、該ハウジング２９の内方に設けられたスピーカ本体４３とから構成し、スピーカグリル１５とハウジング２９によってシートバック５の表層部１１を挟持しているため、この挟持された表層部１１が厚み方向に圧縮されて、スピーカグリル１５の外周部２１の端縁２３とシートバック５の表層部１１との間の隙間が大幅に低減されてシートベルト９が入り込むことがなくなる。   The speaker device 13 includes a speaker housing 29 embedded in the recess 41 and a speaker main body 43 provided inside the housing 29. The speaker grill 15 and the housing 29 are used to Since the surface layer portion 11 is sandwiched, the sandwiched surface layer portion 11 is compressed in the thickness direction, and a gap between the edge 23 of the outer peripheral portion 21 of the speaker grille 15 and the surface layer portion 11 of the seat back 5 is formed. The seatbelt 9 is prevented from entering by being greatly reduced.

そして、前記表層部１１を、表面側に設けた表皮３７と、該表皮３７の裏面側に設けた、伸縮量が大きいウレタン樹脂３９とから構成しているため、スピーカグリル１５とハウジング２９によってシートバック５の表層部１１を挟持する際に、この挟持された表層部１１が厚み方向に圧縮される圧縮量が大きくなる。   Since the surface layer portion 11 is composed of a skin 37 provided on the front surface side and a urethane resin 39 provided on the back surface side of the skin 37 having a large amount of expansion and contraction, a sheet is formed by the speaker grill 15 and the housing 29. When the surface layer portion 11 of the back 5 is sandwiched, the compression amount by which the sandwiched surface layer portion 11 is compressed in the thickness direction increases.

さらに、前記表層部１１の内方にシートバックパッド３５を設け、該シートバックパッド３５の前記凹部４１近傍における上面４９の位置を、ハウジング２９の上面４７よりも距離ｈ分だけ外方側に配置しているため、スピーカグリル１５の外周部２１の端縁２３を、シートバック５の表層部１１の一般面よりも更に下方に配置させることができる。これによって、スピーカグリル１５の外周部２１の端縁２３とシートバック５の表層部１１との間の隙間がほとんどなくなってシートベルト９が入り込むことがなくなる。   Further, a seat back pad 35 is provided on the inner side of the surface layer portion 11, and the position of the upper surface 49 in the vicinity of the concave portion 41 of the seat back pad 35 is disposed outward from the upper surface 47 of the housing 29 by a distance h. Therefore, the edge 23 of the outer peripheral portion 21 of the speaker grille 15 can be disposed further below the general surface of the surface layer portion 11 of the seat back 5. As a result, there is almost no gap between the edge 23 of the outer peripheral portion 21 of the speaker grill 15 and the surface layer portion 11 of the seat back 5, so that the seat belt 9 does not enter.
