Description

本発明はリクライナーシャフトに関し、より詳細には車両シートの背もたれを一定の角度で回転及び固定できるようにする車両シート用リクライナーシャフトに関する。   The present invention relates to a recliner shaft, and more particularly, to a recliner shaft for a vehicle seat that allows the backrest of the vehicle seat to be rotated and fixed at a constant angle.

自動車の運転者及び搭乗者が座るシートには座板に対して背もたれを前、後方に角度調節が可能なようにするリクライナーを設置することによって、自動車に搭乗した者の搭乗姿勢を運転に適した姿勢に維持したりまたは任意の必要な角度に調節できるようにしている。   By installing a recliner on the seat on which the driver and passengers of the car sit, the angle of the backrest can be adjusted forward and backward with respect to the seat plate, the riding posture of the person riding the car is suitable for driving So that it can be kept in a fixed position or adjusted to any required angle.

このようなリクライナーは座板が設置されるクッションフレームと背もたれが設置されるシートバックフレームが相互ヒンジ結合される両側の部位に設置されており、両側のリクライナーはリクライナーシャフトで連結されて連動する。   Such a recliner is installed on both sides where a cushion frame on which a seat plate is installed and a seat back frame on which a backrest is installed are hinged to each other, and the recliners on both sides are connected by a recliner shaft and interlocked.

搭乗者は手動または自動でリクライナーシャフトを回転させることによってリクライナーを作動させ、背もたれの角度を調節できるが、リクライナーシャフトが回転するとき背もたれが座板に対して前、後方向に回転する。   The passenger can operate the recliner by manually or automatically rotating the recliner shaft to adjust the angle of the backrest, but when the recliner shaft rotates, the backrest rotates forward and backward with respect to the seat plate.

しかし、従来のリクライナーシャフトは中がすべて埋められた丸棒材質で構成され、重量が非常に重いという問題があり、これによって車両の軽量化の傾向に対応できず、全体的な製造原価を上昇させる要因となっている。   However, the conventional recliner shaft is made of a round bar material that is completely filled, and there is a problem that the weight is very heavy, which makes it impossible to respond to the trend of lighter vehicles and raises the overall manufacturing cost. It is a factor to make.
