Specific embodiment
Technical solution of the present invention is described in further detail below by specific embodiment and in conjunction with attached drawing.The present invention
The description as described in orientation is undefined in the normal use state of seat.
Embodiment one: as shown in figures 1 to 6, a kind of Lumbar regulating mechanism, including Lumbar 11, support frame 12, it further include installation
Seat 5, the mounting base 5 are fixedly installed on support frame 12, and the mounting base 5 is equipped with the first mounting groove 51；
Including first support 31 and the returning face plate 32 of 31 rear end of first support is arranged in turnover bracket 3, and the returning face plate 32 is set
It sets in the first mounting groove 51,32 lower end of returning face plate is rotated around the first mounting groove 51,31 front end of first support and Lumbar 11
Rotation connection；
Adjusting block 4, the adjusting block 4 are arranged between returning face plate 32 and the first mounting groove 51, by slide up and down adjusting block 4 with
The rotation angle for adjusting turnover bracket 3 makes Lumbar 11 can be realized front and back and adjusts；
Cover board 2 is installed, the installation cover board 2 is covered on the outside of returning face plate 32 and is fixedly connected with mounting base 5, the installation lid
Plate 2 is equipped with a holding tank 24 for being pierced by and moving up and down for first support 31.
Specifically, as shown in figure 3, being equipped with a groove 52, the returning face plate below first mounting groove 51 in mounting base 5
A crook 321 is correspondingly provided on 32, the crook 321 is in groove 52；Width along adjusting block 4 glide direction, it is recessed
The width of slot 52 is greater than the width of crook 321.32 lower part of returning face plate is equipped with the first protrusion 322, and the installation cover board 2 is equipped with
With the first mounting portion 21 of 322 cooperation of the first protrusion；First mounting portion 21 is equipped with an arc groove 211, the first protrusion 322
Always it is in arc groove 211.
As shown in figure 3, adjusting block 4 has wider part and narrower part along glide direction, formed between wider part and narrower part
One inclined-plane 41 opposite with 32 medial surface of returning face plate.The face can may be other inclined-planes for cambered surface, and the purpose is to be turned over
There are enough activity spaces when rotating plate 32 is close to 51 bottom surface of the first mounting groove.As shown in figure 3, the adjusting block in the present embodiment
Using cambered surface.
The bottom surface of first mounting groove 51 is equipped with the retention bead 53 of an elasticity, the adjusting block 4 and the first installation
The contact surface of 51 bottom surface of slot is equipped with the limiting groove 42 matched with retention bead 53.The retention bead 53 and mounting base 5
It is integrally formed.What the mounting base 5 can be plastic material is also possible to metal material.Specifically, first mounting groove 51
Upper end middle position is equipped with a groove for accommodating retention bead 53, and the retention bead 53 is arranged in groove, the limit
Protrusion 53 is inverted L shape, including horizontal part and rake, the horizontal part are extended by mounting base 5, the rake
Lower end turns forward, and lower end is equipped with a protrusion cooperated with limiting groove 42.
Adjusting block 4 is in close to the rotation fulcrum position (i.e. the lower section of the first mounting groove 51) of returning face plate 32, by external force
Effect, returning face plate 32 rotate, and 32 upper end of returning face plate is close to the bottom surface of the first mounting groove 51, and the inside of returning face plate 32 and cambered surface
41 are affixed；Adjusting block 4 is in the rotation fulcrum position (i.e. the top of the first mounting groove 51) far from returning face plate 32, adjusting block 4
The retention bead 53 of 51 bottom surface of limiting groove 42 and the first mounting groove cooperates, and adjusting block is made to be fixed on the upper of the first mounting groove 51
Side, 32 inside of returning face plate and the wider part of adjusting block 4 offset at this time, and 32 upper end of returning face plate offsets with cover board, and returning face plate is conditioned
Block fixation is in the lock state.
For the adjusting convenient for adjusting block 4, regulation handle 43 is extended in two sides to the adjusting block 4 to the left and right.
In addition to this rotation angle of the returning face plate 32 can also be realized by spring mechanism, when using the mechanism, then
Adjusting block is not needed.Between returning face plate 32 and installation cover board 2, installation cover board 2 is equipped with to be turned over for blocking for the spring setting
The salient point of rotating plate 32, Lumbar 11 are at front position, the spring-compressed, and returning face plate 32 is mounted the salient point card on cover board 2
It is firmly motionless.When the needs of Lumbar 11 are adjusted at rear position, for convenient for manipulation, 32 two sides of returning face plate also can be extended out adjusting
Handle presses forward regulation handle, and returning face plate 32 is flicked, at this time returning face plate 32 can after topple over and 51 bottom surface phase of the first mounting groove
It supports, realizes moving back for Lumbar 11.In addition to this setting that the first mounting groove 51 of inclination also can be used carries out the rotation of returning face plate 32
Angular adjustment, i.e., described first mounting groove, 51 vertical direction are tilted backwards by supreme up and down, the rear end and first of the adjusting block 4
Mounting groove 51 inclined surface cooperation can be moved up and down along the inclined surface of the first mounting groove 51, the front end face of the adjusting block 4 with it is upper
Be right angle between end face, when adjusting block 4 at the bottom when, returning face plate offsets with adjusting block 4, and Lumbar 11 is in front position, when
When adjusting block 4 moves up, returning face plate is tilted backwards by external force, and returning face plate 32 drives first support 31, first support 31
Lumbar 11 is driven, Lumbar 11 is adjusted in rear position.Alternative scheme as described above has very much, but its final purpose
All it is that returning face plate 32 is made to rotate, i.e., the front-rear position of 11 front end of first support occurs
Variation, to adjust the front-rear position of Lumbar 11.
It is described installation 2 upper end of cover board set there are two for fixed installation buckle 22, installation 2 lower end of cover board set there are two peace
Fill hole 23；The card slot 54 cooperated there are two being set in the mounting base 5 with buckle 22.The installation cover board is fixed by above structure
In mounting base.
Embodiment two: the present embodiment and embodiment one the difference is that: revolved around the first mounting groove 51 32 upper end of returning face plate
Turn, i.e., the top of the first mounting groove 51 in mounting base 5 is arranged in the described groove 52.
