Description

本発明は、オフィス等で好適に使用されるソファに関する。 The present invention relates to a sofa suitable for use in offices and the like.

近時のオフィス等においては、リラックス、没頭、雑談・相談等に適した多様な姿勢のサポートを図るべく、通常の事務用椅子だけでなく、ワーク感を感じさせないボリューム感と暖かみのある種々の形態のソファが設置されることもある。 In modern offices, in order to support various postures suitable for relaxing, immersing yourself, chatting, consulting, etc., in addition to regular office chairs, we are introducing various types of voluminous and warm chairs that do not give a feeling of work. A shaped sofa may also be installed.

ところで、従来のソファは、座の後端に背凭れが固設されたものであって、背凭れが前後方向に傾動可能なものではない(例えば、特許文献1を参照)。そこで、多様な姿勢で会話等を行うことができるようにすべく、ソファの背凭れを前後方向に傾動可能にすることが考えられている。 By the way, conventional sofas have a backrest fixed to the rear end of the seat, and the backrest is not tiltable in the front-rear direction (for example, see Patent Document 1). Therefore, in order to make it possible to have a conversation in a variety of postures, it has been considered to make the back of the sofa tiltable in the front and rear directions.

しかしながら、背凭れを前後方向に傾動可能な椅子等においては、背支桿を前後方向に傾動可能なものとし、このような背支桿に背凭れを固定する態様のものが従来多く用いられているが、このような態様のものにおいて背凭れを前後方向に傾動可能にした場合、以下のような不具合が生じうる。すなわち、このような構成の背凭れの下端の高さ位置は背凭れの傾動角度によって異なり、背凭れの傾動角度によっては背凭れの下端と座面との間に大きな隙間ができて座り心地や見栄えが損なわれるという不具合が存在する。 However, in chairs etc. whose backrests can be tilted back and forth, the backrest is tiltable back and forth, and the backrest is fixed to the backrest. However, if the backrest is made to be tiltable in the front-rear direction in such a case, the following problems may occur. In other words, the height position of the lower end of the backrest with such a configuration varies depending on the tilting angle of the backrest. There is a problem that the appearance is impaired.

かかる不具合の存在は、オフィスで用いられるソファに限らず、一般的な家庭等で用いられるものについても同様である。 The existence of such defects is not limited to sofas used in offices, but also applies to sofas used in general homes.
