Automobile seat torsion bar rotating mechanism

Abstract

The invention discloses an automobile seat torsion bar rotating mechanism. The mechanism comprises a backrest body, two angle adjusters, an unlocking handle, a middle linkage shaft, a bottom body anda torsion bar assembly, wherein the torsion bar assembly comprises an end fixing piece, a torsion bar body, a mounting piece and a locking piece, the torsion bar body comprises a fixing section, a connecting section and a rotating section, and the connecting section is connected with the fixing section and the rotating section; the rotating section is fixed on the mounting piece by the locking piece, and the fixed section is fixed on the end part fixing piece; the end fixing part is fixed to one side of the bottom body, the installation part is fixed to the backrest body, the two angle adjusters are installed at the two ends of the bottom body, the middle linkage shaft is installed between the two angle adjusters, the lower portion of the backrest body is installed on the angle adjusters,and the unlocking handle is installed on the side portions of the angle adjusters. The unlocking handle unlocks the angle adjuster, the torsion bar assembly replaces a volute spring to provide power for the whole rotating process, problems that the volute spring is high in cost and insufficient in durability are solved, mounting and dismounting are more convenient, and cost is saved.

Description

technical field [0001] The invention relates to the field of automobiles, in particular to an automobile seat torsion bar rotation mechanism. Background technique [0002] At present, some car rear seats have backrest adjustment function, and there is a recliner linkage mechanism inside. After the backrest adjustment handle is unlocked, the backrest will automatically generate a forward force, which is convenient for backrest adjustment. [0003] But there are following defects in the rotation adjustment process of the existing car rear seats: [0004] 1. In the traditional rear seats on the market, the force is generated by the internal vortex spring mechanism. Since the backrest itself is too heavy to adjust, it needs a forward force to balance. The force is generally The vortex spring reset mechanism, the head and end of the vortex spring are fixed on the seat frame through the bracket, one end is fixed, and the other end is linked with the rotation of the seat back, the...
