Abstract

The invention relates to an adjustment mechanism for a seat back, comprising: a base arranged between the backrest and the vehicle body, one end of the base is fixed to the vehicle body and the other end of the base points to the backrest, the upper part of the base is formed with a The guide groove of the backrest rotation track; the slide bar inserted in the guide groove, one end of the slide bar is fixed on the back of the backrest and the other end of the slide bar points to the body; the locking piece fixed on the body, connected to the slide bar through the lock piece and the base to achieve locking; connected to the base and has an elastic top support, the top support is located at the bottom of the other end of the slide bar, and the slide bar is lifted upward by the elastic force of the top support to eliminate the slide bar and the base The gap in the sliding fit of the channel. The support is supported on the bottom of the slide bar, and its elasticity is used to support the slide bar upwards to eliminate gaps and avoid vibration.

Description

technical field [0001] The invention belongs to the field of seats, in particular to an adjustment mechanism for a seat back. Background technique [0002] Patent US8146996B2 discloses a recliner adjuster for the rear seat backrest of an automobile, see figure 1 A schematic structural view of an inclination adjuster in the prior art is shown. combine figure 1 As shown, the recliner includes a flat curved guide rail and a sliding piece inserted in the guide rail. But there may be play in the sliding fit of the curved rail and slide, for example due to manufacturing tolerances and slight deviations of the sliding path from the track of the backrest. The gap between the sliding fit of the guide rail and the slider may cause shaking or sticking during the adjustment process, wear the structure, and affect the user experience. Contents of the invention [0003] The purpose of the present invention is to overcome the defects of the prior art, provide an adjustment mechanism ...
