The specific embodiment

With preferred embodiment the utility model is described in further detail in conjunction with the accompanying drawings now.These accompanying drawings are the scheme drawing of simplification, basic structure of the present utility model only is described in a schematic way, so it only show the formation relevant with the utility model.

A kind of twin-lock shown in Fig. 1-2 ends reclining apparatus, comprise upper cover plate 1, with seat cushion bonded assembly lower cover 3 and with the big tooth plate 5 of backrest bonded assembly, big tooth plate 5 and upper cover plate 1 movable riveted joint, dispose first main shaft 7 and second main shaft 9 between upper cover plate 1 and the lower cover 3, be connected with the little tooth plate 11 that matches with big tooth plate 5 on first main shaft 7, second main shaft 9 is connected with the main latch 13 that matches with little tooth plate 11, main latch 13 is connected with release lever 15, dispose elastic element 17 between release lever 15 and main latch 13 coupling ends and the upper cover plate 1, be movably set with secondary latch 19 on second main shaft 9, the little tooth plate 11 coaxial little shift forks 21 that match with secondary latch 19 that are connected with, the big tooth plate 5 coaxial big shift forks 23 that match with little shift fork 21 that are fixed with, main latch 13 is the angle setting with secondary latch 19, and main latch 13 and secondary latch 19 are at least partially in same plane, by increasing the lockout mechanism of big shift fork 23 and little shift fork 21, make between back of seat and the cushion be connected more firm, in addition, Joint strenght between big tooth plate 5 and the little tooth plate 11 improves, the back of seat rigidity strengthens, so when transfer at the angle, backrest to rock the gap less relatively, and then require the gap between big and small toothed plate cooperation and the axle to require to reduce, assembling easily, part processing difficulty accuracy requirements such as while tooth plate relatively reduce.

In addition, above-mentioned elastic element 17 is extension spring, by extension spring release lever 15 is connected with upper cover plate 1 with main latch 13 coupling ends, and after main latch 13 rotations, extension spring provides restoring force for main latch 13, guarantees engagement between big tooth plate 5 and the little tooth plate 11.For further with engagement connection between big shift fork 23 and the little shift fork 21, so be connected by spring 25 with upper cover plate 1 at secondary latch 19 ends, thereby guarantee that secondary latch 19 in time resets.For backrest is in time rotated at the angle timing, at the big tooth plate 5 coaxial scrollwork springs 27 that are fixed with, for backrest provides rotational force.

Because big tooth plate 5 links by boss 29 and groove 31 with big shift fork 23, little tooth plate 11 links by boss 29 and groove 31 with little shift fork 21, make that the angle transfers to rock the gap less relatively, and then require the gap between big and small toothed plate cooperation and the axle to require to reduce, assembling easily, part processing difficulty accuracy requirements such as while tooth plate relatively reduce, and have reduced difficulty of processing, and the part processing cost descends relatively simultaneously.

It is as follows that the lock working process is reconciled at the utility model angle:

At first, release lever 15 rotates around second main shaft, 9 clockwise directions, thereby driving main latch 13 rotates around second main shaft 9, main latch 13 1 ends drive little tooth plate 11 along 7 rotations of first main shaft, because little tooth plate 11 is connected with little shift fork 21, little shift fork 21 is also around 7 rotations of first main shaft, and then little tooth plate 11 breaks away from big tooth plate 5, main latch 13 continues around 9 rotations of second main shaft, because main latch 13 and secondary latch 19 are at least partially in same plane, main latch 13 is rotated drive secondary latch 19 around 9 rotations of second main shaft, follow secondary latch 19 and drive little shift fork 21 around 7 rotations of first main shaft, and then little shift fork 21 and big shift fork 23 are broken away from, and realize releasing process, guarantee backrest is rotated within the specific limits.

With above-mentioned foundation desirable embodiment of the present utility model is enlightenment, and by above-mentioned description, the related work personnel can carry out various change and modification fully in the scope that does not depart from this utility model technological thought.The technical scope of this utility model is not limited to the content on the specification sheets, must determine its technical scope according to the claim scope.
