Description

Disc type does not have the gap recliner

Technical field

The utility model belongs to the automobile seat accessories technical field, be specifically related between a kind of chair back that is used to be installed in seat and the seat support, can suitably regulate the chair back and not have the gap recliner with disc type with respect to the automotive seat of the angle between the seat support

Background technology

The function of angle regulator for automobile chair is being taken on the function that changes back of seat swing angle as mentioned above, must join on automotive seat as this device.At present, the recliner that is applied on the automobile seat comparatively common on the market is the disc type recliner, and it mainly comprises a reaction plate, an Advance plate and a lockable mechanism, is used to keep the obliquity and attitude of backrest with respect to seat cushion.Lockable mechanism comprises that one is positioned at tooth bar circle and several ratchets on the Advance plate, all has a plurality of teeth on each ratchet wherein.Ratchet can radially move between a lock position and a unlocked position.When ratchet is in lock position, the teeth on the ratchet will with the tooth bar circle interlocking on the Advance plate, thereby can locking backrest with respect to the incident angle of seat cushion.Can obtain detailed understanding in the technical scheme by previous disclosed Chinese utility model patent Granted publication CN2712705Y to this.This patent scheme discloses a kind of " omnipotent recliner ", its achievement part is: locking intensity height, the displacement angle is little, setting range is wide, endplay is little, degree of balance is good, simple in structure, volume is little, advantage easy for installation, but also expose following problem in actual use: all be in the sliding tray of reaction plate moving linearly respectively because of little tooth plate and lobe plate, and the action between the blocked ear groove by little tooth plate and the blocked ear of lobe plate both sides realizes the locking and the disengagement of recliner, so to the requirement on machining accuracy height of parts, the difficult control of the conformability in recliner gap.And for example, Chinese utility model patent Granted publication CN201520234U discloses a kind of " angle regulator for automobile chair of structural development ", and its achievement part is: volume is little, simple in structure, easy to assembly, and two stressed contact surfaces are arranged during locking; Effect simultaneously, reliable lock, gap are little, convenient for unlocking, intensity height, good, the dependable performance of dexterity of action, and applied widely, and productive costs is low.But also expose following point in actual use: 1, since three little tooth plates to be complete cycle uniform, so on gear ring, no teeth groove can't be set; On fluted disc and little tooth plate, the neutral gear position limiting structure is not set again simultaneously, thereby does not have neutral position, can not change the angle of recliner fast; 2,, thereby there is not the gap design that disappears owing to the rotation by driver train drives little tooth plate moving linearly, thus high especially to the requirement on machining accuracy of straight-line groove, the bad control in the gap of recliner.

For this reason, the applicant has carried out useful exploration, finds a way to resolve the problem, and technical scheme described below produces under this background
