Description

本発明は、枠状のシートフレームと、シートフレーム上に配置するシートパッドと、シートフレームの枠内でシートパッドを支持する支持部材と、気体を送り出し可能な送風装置とを備えた乗物用シートに関する。 The present invention relates to a vehicle seat comprising a frame-shaped seat frame, a seat pad disposed on the seat frame, a support member that supports the seat pad within the frame of the seat frame, and a blower that can send out gas. About.

この種の乗物用シートとして、シートクッションが、シート骨格をなす枠状のシートフレームと、シートパッドと、支持部材と、送風装置を備える乗物用シートが公知である（特許文献１を参照）。シートパッドは、シート外形をなして乗員を弾性的に支持する部材であり、シートパッドを厚み方向に貫通する送風路が形成される。この送風路は、シートパッドの着座側に開口する複数の吹出孔と、シートパッドの裏面に開口する溝状の送風溝部を有する。また送風装置は、気体を送り出し可能な直方体状の箱体であり、気体の流路となる管状のダクト部材を備える。また支持部材は、上面視で略矩形の支持枠体と、気密性を備えた面状の面状体とを有する。この面状体は、その周縁で支持枠体に固定されて保持されており、面状体の裏面から突出する掛止部材と、面状体を厚み方向に貫通する口枠体を備える。口枠体は、気体が通過可能な流入孔が設けられており、この流入孔が、シートパッドの送風溝部に対面可能な位置に配置する。 As this type of vehicle seat, a vehicle seat including a frame-shaped seat frame in which a seat cushion forms a seat skeleton, a seat pad, a support member, and a blower is known (see Patent Document 1). The seat pad is a member that elastically supports an occupant with a seat outer shape, and an air passage that penetrates the seat pad in the thickness direction is formed. The air passage has a plurality of blowout holes that are opened on the seating side of the seat pad and a groove-like air groove that opens on the back surface of the seat pad. The blower is a rectangular parallelepiped box that can send out gas, and includes a tubular duct member that serves as a gas flow path. Further, the support member includes a substantially rectangular support frame body in a top view and a planar sheet body having airtightness. The planar body is fixed and held on the support frame body at the periphery thereof, and includes a hooking member protruding from the back surface of the planar body and a mouth frame body that penetrates the planar body in the thickness direction. The mouth frame body is provided with an inflow hole through which gas can pass, and the inflow hole is disposed at a position where the inflow hole can face the air blowing groove portion of the seat pad.

公知技術では、シートフレーム内に支持部材を取付けるとともに、支持部材の裏面側に送風装置を配設する。このとき面状体の裏面に設けた掛止部材に送風装置を掛止して吊下げつつ、ダクト部材を口枠体の流入孔に連通する。そしてシートパッドを、シートフレーム上に配置しつつ表皮で被覆する。このとき面状体にて、シートパッドを支持しながらその裏面側の送風溝部を閉鎖しつつ、口枠体の流入孔のみを、シートパッドの送風路に連通する。こうして乗員の着座時において、着座側から押圧されたシートパッドを面状体が弾性的に凹み変形しつつ支持する。そして送風装置から送り出される気体が、ダクト部材と流入孔を通じて送風路の各吹出孔から着座側に吹出される。 In the known technique, a support member is mounted in the seat frame, and a blower is disposed on the back side of the support member. At this time, the duct member is communicated with the inflow hole of the mouth frame body while the air blower is hooked and hung on the hook member provided on the back surface of the planar body. Then, the seat pad is covered with the skin while being placed on the seat frame. At this time, only the inflow hole of the mouth frame is communicated with the air passage of the seat pad while supporting the seat pad and closing the air blowing groove on the rear surface side with the planar body. In this way, when the occupant is seated, the planar body supports the seat pad pressed from the seating side while being elastically dented and deformed. And the gas sent out from an air blower blows off to the seating side from each blowing hole of a ventilation path through a duct member and an inflow hole.

ところで公知技術では、送風装置が、掛止部材を介して面状体に直接的に取付けられる。そして面状体が、その周縁だけで支持枠体に固定されるため、支持枠体で振動を吸収できず面状体に振動が伝達されやすい構成である。このため公知技術の構成は、送風装置の作動時に面状体が過度に振動することで、やや着座性に劣る構成になりがちであった。もっとも送風装置を、シートフレームに固定して面状体の裏面に配設することもできる。しかしそうすると乗員の着座時において、凹み変形した面状体が送風装置に当たるなどして、乗員に対して硬さなどの違和感を生じさせるおそれがある。本発明は上述の点に鑑みて創案されたものであり、本発明が解決しようとする課題は、送風装置を、支持部材の裏面側に性能良く配設することにある。 By the way, in a well-known technique, an air blower is directly attached to a planar body via a latching member. And since a planar body is fixed to a support frame body only by the periphery, it is a structure which cannot absorb a vibration with a support frame body but is easy to transmit a vibration to a planar body. For this reason, the configuration of the known technique tends to be a configuration slightly inferior in seating because the planar body vibrates excessively when the blower is operated. Of course, the blower can be fixed to the seat frame and disposed on the back surface of the planar body. However, when the occupant is seated, the concavely deformed planar body hits the air blower, which may cause the occupant to feel uncomfortable such as hardness. The present invention has been devised in view of the above points, and a problem to be solved by the present invention is to arrange a blower with good performance on the back side of a support member.

上記課題を解決するための手段として、第１発明の乗物用シートは、シート骨格をなす枠状のシートフレームと、シート外形をなして乗員を弾性的に支持可能なシートパッドと、シートパッドを厚み方向に貫通する流路部と、シートパッドを支持する支持部材と、気体を送り出し又は吸い込み可能な送風装置とを備える。また支持部材が、シートパッドを支持可能な通気性を備える面状体と、面状体を保持可能な枠状体とを有する。本発明では、シートフレームの枠内に枠状体を取付けて、枠状体に保持された面状体にてシートパッドをその裏面側から支持する。また送風装置を、面状体の裏面側に設けて、面状体を通じて送風装置と流路部の間で気体の行き来を可能とした。この種の構成では、送風装置を、支持部材の裏面側に性能良く（例えば着座性良く）配設できることが望ましい。 As means for solving the above-mentioned problems, a vehicle seat of the first invention includes a frame-like seat frame forming a seat skeleton, a seat pad that forms a seat outer shape and can elastically support an occupant, and a seat pad. A flow path portion penetrating in the thickness direction, a support member for supporting the seat pad, and a blower capable of sending or sucking gas are provided. The support member includes a planar body having air permeability capable of supporting the seat pad and a frame body capable of holding the planar body. In the present invention, a frame-like body is attached within the frame of the seat frame, and the seat pad is supported from the back side by the planar body held by the frame-like body. Moreover, the air blower was provided in the back surface side of the planar body, and gas came and went between the air blower and the flow-path part through the planar body. In this type of configuration, it is desirable that the blower can be arranged with good performance (for example, good seating property) on the back side of the support member.

そこで本発明では、送風装置が、伸縮可能な連結部材を介してシートフレームに取付けられる。そして面状体が、シートパッドを支持しつつ着座側から離れる方向に凹み変形する際に、送風装置を、連結部材を伸張させながら凹み変形する面状体に追従させる構成とした。本発明では、送風装置を、連結部材を介して面状体の凹み変形に追従させることで、乗員に対して送風装置が原因の異物感を極力感じさせない構成とすることができる。また送風装置を、連結部材を介してシートフレームに取付けることにより、送風装置の振動を連結部材にて好適に吸収できる。 Therefore, in the present invention, the blower is attached to the seat frame via a connecting member that can be expanded and contracted. When the planar body is recessed and deformed in the direction away from the seating side while supporting the seat pad, the blower is configured to follow the planar body that is recessed and deformed while extending the connecting member. In this invention, it can be set as the structure which does not make the passenger | crew feel as much as possible the foreign material sensation caused by the air blower by making the air blower follow the dent deformation of the planar body via the connecting member. Further, by attaching the blower device to the seat frame via the connecting member, the vibration of the blower device can be suitably absorbed by the connecting member.

第２発明の乗物用シートは、第１発明の乗物用シートであって、連結部材が、面状体に対面可能に配置する面状のダクト部と、ダクト部を厚み方向に貫通する開口部とを有し、ダクト部の縁部が、開口部から離れるに従って次第に面状体に向けて曲げられてなる。本発明では、連結部材のダクト部によって、送風装置と流路部の間でスムーズな気体の行き来が可能となる。 The vehicle seat of the second invention is the vehicle seat of the first invention, wherein the connecting member is disposed so as to be able to face the planar body, and the opening penetrates the duct portion in the thickness direction. And the edge of the duct portion is gradually bent toward the planar body as the distance from the opening portion increases. In the present invention, smooth passage of gas between the blower and the flow path portion is enabled by the duct portion of the connecting member.

本発明に係る第１発明によれば、送風装置を、支持部材の裏面側に性能良く配設することができる。また第２発明によれば、送風装置を、支持部材の裏面側に更に性能良く配設することができる。 According to the first aspect of the present invention, the blower can be disposed on the back side of the support member with good performance. Moreover, according to the 2nd invention, an air blower can be arrange | positioned further with sufficient performance in the back surface side of a supporting member.

In this embodiment, the seat pad 4P is covered with the seat cover 4S while being disposed on the frame-like seat frame 4F. As will be described later, the seat pad 4P is supported by a planar body 24 of a support member 20 disposed in the frame of the seat frame 4F.

In this type of configuration, it is to be avoided as much as possible that the dent deformation of the planar body 24 is obstructed by the blower 30 from the viewpoint of improving seating of the seat. Therefore, in the present embodiment, with reference to FIGS. 7 and 8, the blower 30 is attached to the seat frame 4 F via the connecting member 50 that can be expanded and contracted. And the planar body 24 contacts the contact part 44 of the main-body part 41 because the planar body 24 dents and deform | transforms in the direction away from a seating side, supporting the seat pad 4P. In this state, as the planar body 24 is further recessed and deformed, the blower device 30 pressed by the planar body 24 moves downward while extending the connecting member 50 and follows the planar body 24 that is deformed into a recess. . As described above, in this embodiment, the air blower 30 is caused to follow the planar body 24 via the connecting member 50 so that the occupant CM is not caused to feel as much foreign matter as possible due to the air blower 30.

It can be configured. Further, since the surface of the main body 41 of the duct member 40 and the planar body 24 are spaced apart by the amount of the abutting portion 44, a clearance that allows the passage of gas can be ensured between them. Further, by attaching the blower device 30 to the seat frame 4 F via the connecting member 50, the vibration of the blower device 30 can be suitably absorbed by the connecting member 50. For this reason, according to the present Example, the air blower 30 can be arrange | positioned with sufficient performance in the back surface side of the supporting member 20. FIG.

In addition to the stretchable material, the stretchable portion can be formed of various stretchable and shortenable members such as a stretchable rod and a bellows-like tube material. Moreover, the attachment method of the connection member with respect to an air blower and a seat frame can take various methods besides the fastening by the bolting of an Example.

また本実施形態では、送風装置３０（送風ファン３２，ブラケット３４，ダクト部材４０）の構成を例示したが、同部材の構成を限定する趣旨ではない。例えばダクト部材は、本実施例のように面状であってもよく管状であってもよい。また送風ファン自体に、伸縮部材とダクト部材を取付けて、ブラケットを省略する構成であってもよい。またダクト部材の形状は、周縁部が屈曲又は湾曲していてもよく、また周縁部が曲げられていない平面状であってもよい。また送風ファンとブラケットとダクト部材の取付け方法も適宜選択可能である。そして送風ファンは、気体を送り出し可能な構成のほか、気体を吸い込み可能な構成でもよい。 Moreover, in this embodiment, although the structure of the air blower 30 (The ventilation fan 32, the bracket 34, the duct member 40) was illustrated, it is not the meaning which limits the structure of the same member. For example, the duct member may be planar as in the present embodiment or may be tubular. Moreover, the structure which attaches an expansion-contraction member and a duct member to a ventilation fan itself, and abbreviate | omits a bracket may be sufficient. Moreover, the shape of the duct member may be bent or curved at the periphery, or may be a flat shape where the periphery is not bent. Moreover, the attachment method of a ventilation fan, a bracket, and a duct member can also be selected suitably. The blower fan may have a configuration capable of sucking gas in addition to a configuration capable of sending gas.
