Description
Technical field
The invention belongs to the automobile seat accessories technical field, be specifically related to a kind of be used between the chair back that is installed in seat and the seat support, can suitably regulate the chair back with respect to the high strength recliner of angle between the seat support, be the improvement to existing high strength recliner structure.
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 at 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 for keeping backrest with respect to the obliquity and attitude of seat cushion.Lockable mechanism comprises that one is positioned at tooth bar circle and several ratchets on the Advance plate, has a plurality of teeth on each ratchet wherein.Ratchet can be radially mobile between a lock position and a unlocked position.When ratchet is in lock position, the teeth on the ratchet will with Advance plate on tooth bar circle interlocking, thereby can the locking backrest with respect to the incident angle of seat cushion.Can obtain detailed understanding in the technical scheme by previous disclosed Chinese invention patent Granted publication CN101875321B to this.This patent scheme discloses a kind of " angle regulator for automobile chair of structural development ", its achievement part is: volume is little, simple in structure, easy to assembly, there are two stressed contact surfaces to act on simultaneously during locking, reliable lock, gap are little, convenient for unlocking, intensity height, good, the dependable performance of dexterity of action, and applied widely, 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; At 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, the sliding tray that cooperates with little tooth plate is longer, thus high especially to the requirement on machining accuracy of straight-line groove, the bad control in the gap of recliner; 3, two stressed contact surfaces are arranged during locking, thus very high to the contact surface requirement on machining accuracy of lobe plate and little tooth plate, be easy to occur the unreliable phenomenon of locking; 4, because spring when assembling one end colludes in the spring hole, under the rebound action of spring self, it is not in place to be easy to produce the spring assembling, causes entire product release and locking to lose efficacy.And for example, Chinese utility model patent Granted publication CN202966015U discloses a kind of " a kind of high strength recliner ", and its achievement part is: the conformability that can guarantee many pieces little tooth plate actions; Reliable lock; Convenient for unlocking, flexible movements; The intensity height; The gap is little; Neutral position is arranged, can change the angle of recliner fast; Parts are few, assembling, easy to process, and cost is low; Applied widely.But also expose following point in actual use: higher to the requirement on machining accuracy of locking face because little tooth plate and latch segment are formed with four stressed contact surfaces, in the alternation fatigue process, the slip teeth phenomenon appears easily.
In view of above-mentioned prior art, the applicant has done useful design, has formed technical scheme described below finally, and the production plant area the applicant has carried out analogue test under the strict secrecy provision having taked, and it is practicable that the result proves.
Summary of the invention
