A recliner capable of adjusting idle travel

Abstract

The invention discloses an angle adjuster capable of adjusting an empty stroke. The angle adjuster comprises a main board, a cam, a locking plate, a control panel, a toothed plate and a stroke controlpiece, wherein the stroke control piece is mounted on the toothed plate through a multi-angle fixing mechanism, the stroke control piece is provided with a stroke adjustment profile, a stroke controlprofile and the stroke adjustment profile are overlapped and combined to form an adjustable stroke profile, and a high bulge group is further in contact with the adjustable stroke profile, wherein the adjustable stroke profile comprises an adjustable empty stroke profile and an adjustable locking stroke profile. The angle adjuster can realize the reasonable configuration of the non-empty stroke and the empty stroke; the angle of the adjustable empty stroke profile in the adjustable stroke profile can be changed, the adjustable empty stroke profile is matched with the high bulge group to realize various empty strokes, the types of stroke control pieces are effectively reduced, and the manufacturing and assembly costs are reduced; and at the same time, the defect that an existing stroke control piece is prone to being abrasion when in the first locking position can further be overcome.

Description

technical field [0001] The invention relates to the technical field of angle adjusters, in particular to an angle adjuster capable of adjusting idle travel. Background technique [0002] The recliner is a device installed on the car seat to adjust the angle of the seat back. As a safety part of the car seat, the recliner must not only ensure sufficient strength, but also satisfy the comfort and convenience of operation. Therefore, the manual non-continuous recliner must have the necessary idle stroke (ie, non-locking stroke) to achieve the purpose of quickly adjusting the backrest angle without keeping the unlock, especially suitable for the function of giving way to the rear row of front seats , and the quick flip function of the rear seats. [0003] Currently, the idle travel of the discontinuous manual recliner has the following two forms of realization: [0004] 1) The idle stroke feature is integrated on the gear plate parts. The specific implementation methods are: ...

AI Technical Summary

Problems solved by technology

This method is inconvenient to change the empty stroke area, and the change cost is high

[0005] 2) Add a specific stroke control piece: one kind of control piece only corresponds to one kind of empty stroke, the function is single, and the stroke requirements of customers are various, resulting in a wide variety of parts and small differences between parts (the characteristic difference is about 1mm), making it difficult to prevent mistakes , which is not conducive to subsequent quality control
