Description

本発明は、座部と背もたれとを備え、一体的に作られた構造体を有する車両シートに関する。
本出願は、２０１２年５月７日出願の米国出願第６１／６４３５８７号の優先権を主張するものであり、この米国出願の全内容が参照により本明細書に含まれるものとする。
このような車両シートは、特許文献１から知られている。自動車工学では、このような車両シートをより容易に且つ／又はコスト効率良く製造することが可能になるという継続的な要求がある。
独国特許出願公開第１０２０１１１０６２１９号明細書
したがって、本発明の目的は、上記要件を満たす車両シート又は車両シートの個々の構成要素を提供することであった。
上記目的は、座部と背もたれとを有する車両シートであって、座部及び／又は背もたれ、特にその側部の支持構造体が少なくとも１つのばね要素、ピボット点及び／又は安全ベルト接続部を一体的に有する車両シートによって達成される。
本発明は、座部と背もたれとを有する車両シートに関する。
本発明によれば、座部及び／又は背もたれ、特にその側部の支持構造体が、少なくとも１つのばね要素、傾き調節装置の一部及び／又は安全ベルト接続部を一体的に有する。
好ましくは、座部及び／又は背もたれは、プラスチック材料、特に繊維強化プラスチック材料から製造される。座部及び／又は背もたれは、好ましくは、樹脂によって結合された繊維構造体を提供することにより製造される。構造体は、変形することなくツールから構造体を取り外すことができるくらい堅くなるとすぐに、好ましくはプラスチック材料をオーバーモールドされる。
好ましい実施形態では、座部及び／又は背もたれの側部の少なくとも支持構造体は、一体的に、すなわち単一部品として設けられる。
好ましい実施形態では、座部及び／又は背もたれはシートシェル及び／又はクロスメンバーを一体的に有する。好ましくは、シートシェルはばね要素を一体的に備える。好ましくは、シートシェルは、例えば、側部とシートシェルとの間及び／又は側部自体にあるばね要素によって、座部の支持構造体の側部に対して移動可能に設けられる。
好ましくは、シートシェルの高さ調節装置は、座部の支持構造体の側部に組み込まれる。より好ましくは、シートシェルの後方及び／又は前方領域は、座部の支持構造体の側部に対して高さを調節可能である。
例えば、座部の側部にばねが設けられ且つ伸ばされ、その結果としてシートシェルが上昇する。好ましくは、側部は少なくとも１つのくさび形面を有し、くさび形面に沿って要素が移動させられ、その過程でクッションシェルを上昇及び下降させる。
好ましくは、座部の支持構造体はクロスメンバーを一体的に有し、シートシェルは前部衝突の際にクロスメンバーに支持される。
好ましくは、座部の支持構造体の側部が、前後方向シート調節装置のアッパーレールと一体的に設けられる。
好ましくは、背もたれが、傾き調節装置の少なくとも一部を一体的に有し、且つ／又はヘッドレストの少なくとも一部を一体的に有する。
本発明によれば、車両シート全体を、特にプラスチック材料、好ましくは繊維強化プラスチック材料から一体的に製造することも可能である。
本発明の他の好ましい又は独創的な実施形態は、座部及び／又は背もたれが粒子で満たされたクッションを有する車両シートである。
これらの粒子により、クッションは乗員の臀部及び／又は背中の形状に適合する。好ましくは、粒子は、クッション内でのそれらの移動が制限されるように、区画内に設けられる。粒子は、発泡スチロールなどから作ることができる。
本発明は、図１〜５に基づいて以下の本文で説明される。これらの説明は、例示に過ぎず、本発明の一般概念を限定するものではない。
一体的な座部を概略的に示す。 一体的な座部を概略的に示す。 ばね要素を有するシートシェルを示す。 図１及び１ａに係る座部の構造体の製造を示す。 図１及び１ａに係る座部の構造体の製造を示す。 粒子を有するクッションを示す。
互いに対応する部分には、図面のすべてにおいて同じ符号が付されている。
本発明は、座部２と背もたれ３とを有し、背もたれが、背もたれをその使用から例えばイージーエントリー位置へ移動させることができるように、且つ／又は快適さのために背もたれの傾きを調節するために、旋回可能に座部に設けられた車両シート１に関する。シートは、好ましくは前後方向調節装置を備える。
図１に示す本発明に係る車両シート１の実施形態では、座部２の少なくとも構造体が、一体的に構成され、すなわち単一部品として作られる。好ましくは、座部２は、プラスチック部品として、特に繊維強化プラスチック部品として構成される。座部２の側部には、前後方向調節装置４に属するアッパーレール４３が一体的に配置される。また、座部２の側部は、少なくとも１つのばね要素４０を有し、シートシェル４１とアッパーレール４３との間の距離Δｈが変更された結果、ばね要素４０が弾性的に伸張又は収縮するという点で、ばね要素によってシートシェル４１の高さ調節をもたらすことができる。好ましくは、２つのばね要素４０は異なるばね特性を有し、特に好ましくは、着座者の後方の領域にあるばねは、大腿部レストの領域にあるばねよりも硬いばね特性を有する。また、座部の側部に歯部１６が一体的に設けられ、前記歯部１６は本発明に係る車両シートのリクライナの一部である。さらに、本発明に係る車両シートは、２つのクロスメンバー４２を一体的に有し、クロスメンバーは、座部の右側及び左側に配置された２つの側部を互いに接続する。また、背もたれ３の旋回軸は、座部２に一体的に配置される。さらに、座部は、好ましくは、背もたれのピボット軸受Ｐを一体的に有する。座部２はまた、シートシェル４１とばね要素３１とを一体的に備え、ばね要素は背もたれと座部との間に設けられる。
図１ａは、実質的に図１による実施形態を示し、この例では、背もたれ３の傾斜角度の調節とシートシェルの高さ調節が示されている。傾き調節装置は、不連続な又は連続的な調節装置であることができる。レバーの動きは、例えば、背もたれの調節のロックを解除することができ、乗員はその後自分の体に合わせて背もたれの傾きを調節する。代わりに又は加えて、レバーは歯車を駆動することができ、歯車は歯部１６上を転動し、結果として背もたれの傾きを調節する。当業者は、少なくとも１つの、好ましくは２つの歯車が歯部１６と噛み合うという点において、調節を電動式に行うこともできることを理解するであろう。高さは、好ましくはハンドホイール５９によって調節され、ハンドホイールは、例えば、シートシェルを上向きに押すカムを駆動する。この調節装置は、「潜り込み現象」に関して座部に十分な安定性を与えるために、座部の前方３分の１に設けられる。高さ調節が作動すると、ばね４０が伸ばされる。シートシェルは、ばね４０によって下降位置に戻される。調節機構５９に力伝達手段６０を連結することができ、ハンドホイールを作動させると、前記力伝達手段６０が着座者の後部の領域でばねを作動させるので、前記ばねのばね偏位は前方のばねのばね偏位と異なる。結果として、ばね４０の伸展を別々に行うことができる。
図２は、一体的に設けられたばね要素４０を有するシートシェル４１を示す。これにより、必要とされる部品の数が減少する。
図３及び図４は、座部の製造を示す。図３から分かるように、ツール内に、樹脂で固定された繊維構造体が設けられる。構造体がもはや変形しないように樹脂が十分に固化するとすぐに、構造体はツールから取り外され、第２ツール内で又は槽内でプラスチック層をオーバーモールドされる。
図５は、本発明のさらに別の実施形態を示す。ここでは、クッションが座席構造体とカバーとの間に多数の粒子を備えるので、クッションは着座者の臀部及び／又は背中の形状に適合する。
