Fig. 2 is the partial enlarged view of the adjustment structure of Fig. 1, and Fig. 3 is the explosive view of Fig. 2.The regulating mechanism 4 is pulled including backrest
Machine 41, fixing axle 42, linkage mechanism baffle 43, thrust cap 44, returning spring 45, idler wheel 46, roller bearing 47 and driving idler wheel
Bracket 48.
Referring to Fig. 1, backrest frames 1 have backrest side plate 11, and backrest trigger 41 is connect by welding with backrest side plate 11.When
When backrest frames 1 are rotated around pivotal axis L, which is rotated with.As shown in figure 3, the backrest trigger 41 has
Inwardly projecting stopper section 411.
Referring to Fig. 1, cushion skeleton 2 has cushion side plate 21, and fixing axle 42 is connect by riveting with cushion side plate 21.Such as figure
Shown in 3, which has inwardly projecting outrigger shaft 421.
As shown in Figures 2 and 3, which includes integrally formed 431 He of lateral plate being generally perpendicular to each other
Connection sheet 432, wherein lateral plate 431 extends generally perpendicular to pivotal axis L (referring to Fig. 1), and connection sheet 432 is in substantially parallel relationship to pivot
Shaft L (referring to Fig. 1) extends.There is the kidney slot 431a being set on outrigger shaft 421, wherein the kidney slot on lateral plate 431
The extending direction of 431a is the vertical direction perpendicular to pivotal axis L (referring to Fig. 1).In this way, lateral plate 431 can be in the vertical direction
It is moved up and down relative to fixing axle 42.In addition, also having spring coupling part 431b on lateral plate 431.
As shown in figure 3, thrust cap 44 is set in the inside (outside that cushion side plate 21 is located at lateral plate 431) of lateral plate 431
On outrigger shaft 421, so that the lateral plate 431 of linkage mechanism baffle 43 is limited in cushion side plate 21 (referring to Fig. 1) and thrust cap 44
Between do not depart from.Preferably, gasket is provided between the lateral plate 431 and thrust cap 44.
As shown in Fig. 2, the first end of returning spring 45 is fixed on the freedom of the separate cushion side plate 21 of outrigger shaft 421
On end, and second end is fixed on the spring coupling part 431b (referring to Fig. 3) of linkage mechanism baffle 43, for replying connection
Motivation structure baffle 43 is always maintained at a position when making it not by outer power drive.
As shown in figure 3, idler wheel 46 is connected in the connection sheet 432 of linkage mechanism baffle 43 by roller bearing 47.
Referring to Fig. 1, rolling wheel support 48 is driven to connect by welding with pedestal 3.As shown in figure 3, the driving rolling wheel support 48
With the flange 481 for being parallel to pivotal axis L extension comprising the first section 481a and the second section on different level
481b.In the present embodiment, the second section 481b is slightly below the first section 481a in the vertical direction.As shown in Fig. 2, connection sheet
432 extend perpendicular to flange 481, and the idler wheel 46 being assemblied in connection sheet 432 slidably cooperates along the bottom surface of flange 481.
Fig. 4 be it is according to an embodiment of the invention with backrest classification adjustment structure seat in the first state
Partial enlarged view, at this point, idler wheel 46 is located at the lower section of the higher first section 481a of the flange 481 of driving rolling wheel support 48,
Returning spring 45 is in tightening state, and the axis 42 that is strained and fixed is located at the kidney slot 431a's of the lateral plate 431 of linkage mechanism baffle 43
Bottom position, linkage mechanism baffle 43 is accordingly in a high position.After backrest frames 1 pivot certain angle backward, it is fixedly connected on
The backrest trigger 41 of backrest side plate 11 is rotated into stop dog position, to contact linkage mechanism gear by stopper section 411 outstanding
The rear end of piece 43, backrest frames 1 can not continue to pivot backward and limit a lesser rotatably range.It should be understood that should be only
Stopper 411 is not intended to limit the pivot forward of backrest frames 1.
Fig. 5 be it is according to an embodiment of the invention with backrest classification adjustment structure seat in the second condition
Partial enlarged view, cushion skeleton 2 (referring to Fig. 1) are slided along the direction for being parallel to pivotal axis L, and idler wheel 46 is located at driving idler wheel
The lower section of the lower second section 481b of the flange 481 of bracket 48, returning spring 45 are in elongated condition, pull fixing axle 42
Positioned at the top position of the kidney slot 431a of the lateral plate 431 of linkage mechanism baffle 43, linkage mechanism baffle 43 is accordingly in low level.
When backrest frames 1 pivot backward, although the backrest trigger 41 for being fixedly connected on backrest side plate 11 is rotated into stop dog position,
It is that the stopper section 411 outstanding can not contact linkage mechanism baffle 43 (since linkage mechanism baffle 43 is located at low level), leans on spine
Frame 1 can continue to pivot backward and limit a biggish rotatably range.
It should be understood that stopper section 411 can play backstop action mainly by linkage mechanism baffle 43 in the vertical direction
Height determines, and the height determines by the flange 481 of driving rolling wheel support 48.Therefore, as needed, this can be turned over
Side 481 is provided with multiple stepped portions.Fig. 6 a- Fig. 6 c is according to another embodiment of the invention with backrest classification adjusting
Partial enlarged view of the seat of structure under three states, wherein flange include the first section 481a ', the second section 481b ' and
Third section 481c ', so as to limit different range of pivot etc. in three different positions.
Fig. 7 is the partial enlargement of the seat with backrest classification adjustment structure according to still another embodiment of the invention
Figure, unlike above embodiment, cushion skeleton is along direction (the i.e. front and back perpendicular to pivotal axis shown in arrow
To) slided, linkage mechanism baffle 43 ' at this time only includes the lateral plate 431 ' extended generally perpendicular to pivotal axis, without
It is in substantially parallel relationship to the connection sheet of pivotal axis extension, idler wheel 46 ' is connected to the side of linkage mechanism baffle 43 by roller bearing at this time
On piece 431 '.
Above-described, only presently preferred embodiments of the present invention, the range being not intended to limit the invention, of the invention is upper
Stating embodiment can also make a variety of changes.Made by i.e. all claims applied according to the present invention and description
