Description

本発明は、チャイルドシートの載置、装着に適したシートクッションフレーム構造に関する。   The present invention relates to a seat cushion frame structure suitable for placing and mounting a child seat.

自動車等のシートにおける乳幼児等用補助座席、いわゆるチャイルドシートは、通常、シートクッション上に載置され、その後端をシートベルト、あるいは専用の取付装置等で連結、支持することにより装着される(特開2003−25882号公報等参照)。   An auxiliary seat for infants or the like in a seat of an automobile, for example, a so-called child seat is usually placed on a seat cushion and is mounted by connecting and supporting the rear end thereof with a seat belt or a dedicated attachment device (Japanese Patent Application Laid-Open (JP-A)). 2003-25882 publication etc.).

ところで、この種のチャイルドシートは、通常、シートクッションの、シートパッド等の弾性体上に載置されているにすぎないため、衝突等の際に発生する前方への慣性力等によりチャイルドシートの前端部に過剰な負荷が作用されると、シートクッションの弾性に抗したチャイルドシート前端部の沈み込みによるその前傾が伴われる。   By the way, this kind of child seat is usually only placed on an elastic body such as a seat pad of the seat cushion, and therefore the front end portion of the child seat is caused by a forward inertial force generated in the event of a collision or the like. When an excessive load is applied to the seat cushion, its forward tilt is caused by the sinking of the front end of the child seat against the elasticity of the seat cushion.

一般に、チャイルドシートに着座した乳幼児等の上体は、3点式等の専用ベルトにより拘束されるため、このようなチャイルドシートの前傾のもとでも別段危険性は伴われない。しかし、このチャイルドシートの過剰な前傾は、その安定性等の点において好ましいとはいえない。   In general, the upper body of an infant or the like seated on a child seat is restrained by a dedicated belt such as a three-point type, and thus there is no particular danger even under such a forward tilt of the child seat. However, this excessive forward tilt of the child seat is not preferable in terms of its stability.

ここで、たとえば、チャイルドシート前端の沈み込みを規制可能とする受け金をシートクッションフレームの前端部に固着した構成が、特開2003−154878号公報に開示されている。このような構成であれば、下方からのこの受け金による支持のもとで、チャイルドシート前端の沈み込みが抑制されるため、衝突等の衝撃発生時においても、その安定性等は十分に高く維持される。   Here, for example, Japanese Patent Application Laid-Open No. 2003-154878 discloses a configuration in which a receiver that can regulate the sinking of the front end of the child seat is fixed to the front end of the seat cushion frame. With such a configuration, since the sinking of the front end of the child seat is suppressed under the support by the backing from below, its stability is maintained sufficiently high even when an impact such as a collision occurs. Is done.

しかしながら、この公知の構成における受け金は、複雑な曲げ加工により形成された金属製丸棒材であり、また、別部材であることから溶着等の相応の組立工程が必要となるため、構成の複雑化およびコストの上昇等を伴うことが否定できない。   However, the receiver in this known configuration is a metal round bar formed by a complicated bending process, and since it is a separate member, a corresponding assembly process such as welding is required. It cannot be denied that it is complicated and cost increases.

そして、このような受け金によってチャイルドシート前端を支持する構成であると、この受け金自体に、チャイルドシートの沈み込みに抗するだけの剛性が要求されるが、この公知の受け金が金属製丸棒材であり、所要の剛性を得るには相応の直径が必要となることから、その大型化に伴う重量化も避けられない。
特開2003−25882号公報 特開2003−154878号公報
And if it is the structure which supports a child seat front end with such a receiver, the receiver itself is required to have rigidity sufficient to resist the sinking of the child seat, but this known receiver is a metal round bar. Since it is a material and requires a suitable diameter to obtain the required rigidity, it is inevitable that the weight will increase with the increase in size.
JP 2003-25882 A JP 2003-154878 A

解決しようとする問題点は、金属製丸棒材を曲げ加工してなる受け金であると、構成の複雑化、重量化、およびコストの上昇等を伴いやすいという点である。   The problem to be solved is that a metal base made by bending a metal round bar is likely to be complicated in configuration, increased in weight, and increased in cost.

本発明の請求項1に係るシートクッションフレーム構造は、トリムカバー係止用のパネル状ブラケットを、その前端に一体に備えてなるとともに、シートクッション上に載置、装着されたチャイルドシートの前端部をその下方から支持可能とする支持部を、突出加工によりなる上方突出のビードとして、このパネル状ブラケットの上面壁に一体に形成したことを、その最も主要な特徴としている。   The seat cushion frame structure according to claim 1 of the present invention is provided with a panel-like bracket for locking the trim cover integrally at the front end thereof, and the front end portion of the child seat mounted and mounted on the seat cushion. The main feature is that the support portion that can be supported from below is formed integrally with the upper surface wall of the panel-like bracket as an upward protruding bead formed by protruding processing.

また、この発明の請求項2は、シートクッションフレームの前端にその上方から係合、載置されるものとしてパネル状ブラケットの支持部を形成したことを、その最も主要な特徴としている。   The main feature of claim 2 of the present invention is that the support portion of the panel bracket is formed to be engaged and placed on the front end of the seat cushion frame from above.

本発明の請求項1に示すシートクッションフレーム構造は、トリムカバー係止用のパネル状ブラケットに上方突出のビードを設けることにより、これをチャイルドシートの前端部に対する下方からの支持部としている。つまり、別部材を用いずに、従来からあるトリムカバー係止用のパネル状ブラケットを形状変更するにすぎないため、その構成の簡素化およびコストの低減が確実にはかられるとともに、重量の増加も確実に防止されるという利点が、この請求項1によれば得られる。   In the seat cushion frame structure according to the first aspect of the present invention, a bead protruding upward is provided on the panel-like bracket for locking the trim cover, and this is used as a support portion from below with respect to the front end portion of the child seat. In other words, the conventional panel-like bracket for locking the trim cover is only changed in shape without using a separate member, thus simplifying the configuration and reducing costs and increasing the weight. The advantage that this is reliably prevented is also obtained according to this claim.

そして、この発明の請求項2は、パネル状ブラケットの支持部をシートクッションフレームの前端にその上方から係合、載置させているため、シートクッションフレームへの荷重分散が容易に確保されるという利点がある。   According to the second aspect of the present invention, since the support portion of the panel-like bracket is engaged and placed on the front end of the seat cushion frame from above, load distribution to the seat cushion frame is easily ensured. There are advantages.

衝突時等におけるチャイルドシートの過剰前傾を、別部材を設けることなく防止可能とした。   An excessive forward tilt of the child seat at the time of a collision or the like can be prevented without providing a separate member.

図1、図2は、本発明のシートクッションフレーム構造を示す、シートクッションフレーム10の前端部を表す概略部分斜視図、およびシートクッションフレームの概略側面図であり、これらを見るとわかるように、この発明においては、トリムカバー係止用のパネル状ブラケット12をその前端部に一体に備えるものとして、このシートクッションフレームが形成されている。   FIG. 1 and FIG. 2 are a schematic partial perspective view showing a front end portion of a seat cushion frame 10 and a schematic side view of the seat cushion frame 10 showing the seat cushion frame structure of the present invention. In the present invention, the seat cushion frame is formed as a panel-like bracket 12 for engaging the trim cover integrally provided at the front end portion thereof.

このシートクッションフレーム10は、たとえば、左右一対のサイドフレーム14の前端間、後端間をそれぞれの架設フレーム16,17で一体的に連結することにより、平面略矩形状に形成され、通常は、その前端を連結する前端架設フレーム16が、シートクッションフレーム10の前端として具体化される。   The seat cushion frame 10 is formed into a substantially rectangular plane by integrally connecting the front ends and rear ends of the pair of left and right side frames 14 with the installation frames 16 and 17, for example. A front end erection frame 16 that connects the front ends is embodied as a front end of the seat cushion frame 10.

ここで、このシートクッションフレーム10を骨格部材としてなるシートクッション18は、左右のサイドフレーム14間に架設、張設された複数のSばね20上にシートパッド等の弾性体22を載置し、これら全体をトリムカバー24で覆うことにより形成される。そして、シートクッションフレーム10の前端に設けられたパネル状ブラケット12は、このトリムカバー24の前端の係止に使用されるものであり、図2に示すように、トリムカバー24のフック片26をパネル状ブラケット12の垂下片である前面壁12aに係止することにより、シートクッションフレームに対するこのトリムカバー前端の係止、取り付けは行われる。   Here, the seat cushion 18 having the seat cushion frame 10 as a skeleton member has an elastic body 22 such as a seat pad placed on a plurality of S springs 20 that are laid and stretched between the left and right side frames 14. These are formed by covering the entirety with a trim cover 24. The panel bracket 12 provided at the front end of the seat cushion frame 10 is used to lock the front end of the trim cover 24. As shown in FIG. By engaging the front wall 12a, which is a hanging piece of the panel bracket 12, the front end of the trim cover is locked and attached to the seat cushion frame.

なお、車両用シートのシートクッション、およびその骨格をなすシートクッションフレーム自体は公知であり、これらの基本構成はこの発明の主旨でないため、これらに対する詳細な説明は、ここでは省略するものとする。   In addition, since the seat cushion of a vehicle seat and the seat cushion frame itself that forms the skeleton of the vehicle seat are well known, and the basic configuration thereof is not the gist of the present invention, the detailed description thereof will be omitted here.

ところで、車両用シートにおいて、チャイルドシート28は、図2に示すようにシートクッション18上に載置されるとともに、その後端部を車両用シートのシートベルト、あるいは車両用シートに設けられた専用取付金具等(いずれも図示しない)により連結、支持することにより装着される。   By the way, in the vehicle seat, the child seat 28 is placed on the seat cushion 18 as shown in FIG. 2, and the rear end of the child seat 28 is provided on the seat belt of the vehicle seat or on the vehicle seat. Etc. (both not shown) are connected and supported.

そして、この発明においては、図2に示すように、シートクッション18上に載置、装着されたチャイルドシート28の前端部が、シートクッションフレーム前端のパネル状ブラケット12上に整列する点に着目し、このチャイルドシート前端部をその下方から支持可能とする支持部30を、突出加工によりなる上方突出のビードとして、パネル状ブラケットの上面壁12bに一体に形成するものとしている。   In the present invention, as shown in FIG. 2, paying attention to the point that the front end portion of the child seat 28 placed and mounted on the seat cushion 18 is aligned on the panel-like bracket 12 at the front end of the seat cushion frame, The support portion 30 that can support the front end portion of the child seat from below is integrally formed on the upper surface wall 12b of the panel-like bracket as an upward protruding bead formed by protruding processing.

このように、この発明においては、パネル状ブラケット12に形成した上方突出の支持部30によって、チャイルドシート28の前端部をその下方から支持可能とするものとしている。つまり、この支持部30は、シートクッションフレーム10に従来から設けられたパネル状ブラケット12の形状変更のみによってなるものであるため、衝突等の衝撃による祖の前端部の過剰な沈み込みに伴ったチャイルドシート28の過剰な前傾を防止可能とする構成であっても、その部品点数の増加が確実に防止されるとともに、それに伴うコストの低減も確実にはかられる。   Thus, in the present invention, the front end portion of the child seat 28 can be supported from below by the upwardly projecting support portion 30 formed on the panel-shaped bracket 12. That is, the support portion 30 is formed only by changing the shape of the panel-like bracket 12 conventionally provided in the seat cushion frame 10, and thus accompanied by excessive sinking of the front end portion of the ancestor due to an impact such as a collision. Even if the child seat 28 is configured to prevent an excessive forward tilt, an increase in the number of parts can be reliably prevented, and a cost reduction associated therewith can be reliably ensured.

そして、このようなビード状の支持部30であれば、その形状により、この支持部自体に十分に高い剛性が確保できるため、重量増加を伴うことのない支持強化が容易に確保可能となる。   And if it is such a bead-shaped support part 30, since sufficiently high rigidity can be ensured by this shape in this support part itself, the support reinforcement | strength without accompanying a weight increase can be ensured easily.

ここで、図1、図2に示すように、この発明においては、シートクッションフレーム10の前端、つまり前端架設フレーム16にその上方から係合、載置されるものとして、パネル状ブラケット12のビード状の支持部30が形成されている。   Here, as shown in FIGS. 1 and 2, in the present invention, the bead of the panel bracket 12 is assumed to be engaged and placed on the front end of the seat cushion frame 10, that is, the front end installation frame 16 from above. A shaped support portion 30 is formed.

このような構成であれば、衝突等の衝撃に伴ってチャイルドシート28の前傾方向に過剰な荷重が作用しても、シートクッションフレーム10への荷重分散が容易に確保できるため、パネル状ブラケット12の変形等も確実に防止可能となる。   With such a configuration, even when an excessive load acts in the forward tilt direction of the child seat 28 due to an impact such as a collision, the load distribution to the seat cushion frame 10 can be easily ensured. It is possible to reliably prevent deformation of the material.

上述した実施例は、この発明を説明するためのものであり、この発明を何等限定するものでなく、この発明の技術範囲内で変形、改造等の施されたものも全てこの発明に包含されることはいうまでもない。   The above-described embodiments are for explaining the present invention, and are not intended to limit the present invention. All modifications, alterations, etc. within the technical scope of the present invention are included in the present invention. Needless to say.

この実施例においては、左右一対のサイドフレームの前端間、後端間を前後の架設フレームによって一体的に連結してなる平面略矩形状のものとして、シートクッションフレームを具体化しているが、その前端にトリムカバー係止用のパネル状ブラケットを有すれば足りるため、シートクッションフレーム自体の形状、構成はこの限りでない。   In this embodiment, the seat cushion frame is embodied as a substantially rectangular shape in which the front and rear ends of a pair of left and right side frames are integrally connected by front and rear installation frames. Since it is sufficient to have a panel bracket for engaging the trim cover at the front end, the shape and configuration of the seat cushion frame itself are not limited to this.
