The present invention relates to a gap elimination mechanism. The wedge spring mechanism includes a first wedge, a second wedge, a third wedge, a first spring and a second spring, wherein the first wedge and the second wedge are stacked And one end thereof jointly defines a first wedge retaining surface, the third wedge independently defines a second wedge retaining surface, the first spring is arranged between the first wedge and the third wedge, and the second spring is arranged on the second wedge between the block and the third wedge. The invention also relates to a concentric recliner and an installation method thereof. According to the gap elimination mechanism and its concentric recliner of the present invention, its part structure is relatively simple, and it is easy to produce in large quantities; it has wide applicability and good transplantability, and can be used in various manual electric recliners; the wedge and spring are simple in structure , easy production and low cost. According to the installation method of the concentric recliner of the present invention, there is no need to open an opening on the tooth plate, which is beneficial to production control.
Description
Technical field [0001] The present invention relates to a vehicle seat, and more particularly, to a mechanism to eliminate the gap and a concentric recliner and mounting method. Background technique [0002] A recliner is mounted on a vehicle seat, a seat back angle adjustment means to realize the. At present, there is used a seat recliner Most electric double eccentric. When adjusting the seat back, not done about a point concentric with the rotational movement, but eccentrically rotating with a certain eccentricity. Due to the eccentricity, in the process of movement, not only the longitudinal horizontal direction of displacement, it is also displaced vertically up and down, resulting in a wavy motion of the backrest. This is likely to cause problems such as jitter abnormal sound, can not meet the rapid and smooth adjustment of demand, thus affecting the customer experience. Further, the eccentric gear card death regulation problem prone, and therefore the eccentric adjustable ...
