Description

Automotive seat are used the universal recliner

Technical field

The invention 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 use the universal recliner 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 stated, 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 through 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 is high, the displacement angle is little, setting range is wide, endplay is little, degree of balance is good, simple in structure, volume is little, convenient 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 through little tooth plate and the blocked ear of lobe plate both sides realizes the locking and the disengagement of recliner; So the requirement on machining accuracy to parts is high, 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, high, good, the dependable performance of dexterity of action of intensity, and applied widely, and productive costs is low.But also expose following point in actual use: 1, owing to adopt three little tooth plates, three little tooth plates are complete cycle and are uniformly distributed with, thus on gear ring, no teeth groove can't be set, thereby do not have neutral position, can not change the angle of recliner fast; 2,, and two stressed contact surfaces are arranged during locking because the rotation through driver train drives little tooth plate moving linearly, thus high especially to the requirement on machining accuracy of part, the bad control in the gap of recliner.

For this reason, the applicant has carried out useful exploration, has found the way of dealing with problems, and the technical scheme that will introduce below produces under this background

Summary of the invention

task of the present invention is to provide a kind of automotive seat to use the universal recliner; It not only volume little, simple in structure, easy to assembly, neutral position is arranged and can change angle fast, and reliable lock, convenient for unlocking, the gap is little, intensity is high, dexterity of action is good, dependable performance; Be convenient to processing and fabricating simultaneously and can reduce production costs, applied widely.

task of the present invention is accomplished like this; A kind of automotive seat are used the universal recliner, comprise fluted disc seat, fluted disc, little tooth plate, little tooth plate driver train and closed ring, and be characterized in: described fluted disc seat is a disc; Offer one first axis hole in the axial centre of fluted disc seat; On a side of fluted disc seat, convex with and be used for one group of first positioning boss being connected with seat support seat basin side plate, constitute cavity, in cavity, convex with tooth plate positioning boss and support rim in the centre of fluted disc seat opposite side; The quantity of described tooth plate positioning boss and support rim has two at least; Be distributed on respectively said first axis hole around, in the centre of cavity and be close to the first axis hole place and be concaved with a spring containing cavity, said spring containing cavity is provided with trough of spring hook; Described fluted disc is a disc; Offer one second axis hole in the axial centre of fluted disc; Constitute containing cavity at fluted disc towards the centre of fluted disc seat one side, be formed with inner ring, the outer ring of stepped setting around the outside of said containing cavity respectively, on the circumference of said inner ring, convex with limiting stopper to the second axis hole direction; On the circumferential inner wall of said outer ring, constitute gear ring, on the opposite side of fluted disc, convex with and be used for and one group of second positioning boss of chair back side plate bonded assembly; Described little tooth plate driver train is placed between the containing cavity of cavity and fluted disc of fluted disc seat; This little tooth plate driver train comprises lobe plate, center shaft and spring; The axial centre of said lobe plate offers and is formed with at least two protruding and blocked ears of retaining on the outer of cam plate hole, lobe plate; The centre of said center shaft is provided with axis hole, and the middle part of center shaft is located in the cam plate hole of lobe plate, and an end of center shaft is installed in first axis hole of fluted disc seat rotationally; The other end of center shaft is installed in second axis hole of fluted disc rotationally; Described spring places in the spring containing cavity of fluted disc seat, and the centre of spring has the spring eye that supplies center shaft to pass, and the outer end of spring has the spring that the trough of spring hook that is used for being provided with the fluted disc seat matches; Described little tooth plate has two pieces at least; The shape of each little tooth plate is identical with size; Be fan-shaped; Place respectively in the cavity of fluted disc seat; Be respectively equipped with the tooth plate knock hole that is used to supply the tooth plate positioning boss to insert on each little tooth plate, each little tooth plate is used for nibbling the teeth of joining mutually with gear ring, on fan-shaped interior circular arc, is formed with respectively and is used for the blocked ear groove that matches with blocked ear and is used for and keeps off protruding base of matching being shaped on one section on the fan-shaped external arc respectively, each little tooth plate towards be respectively equipped with on the face of fluted disc one side be used for the positive stop lug boss that cooperates with limiting stopper and be used to eliminate little tooth plate and fluted disc, fluted disc seat between the gap etc. high boss; Described closed ring is encapsulated in the outer perimeter of fluted disc seat and fluted disc.

offer the jump ring groove on the outer wall of an end end of said center shaft in a concrete embodiment of the present invention, in described jump ring groove, be embedded with the jump ring that is used for center shaft is carried out axial restraint.
