Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Specific embodiment described herein only in order to explain the utility model, and is not used in restriction the utility model.In addition, if below in described each embodiment of the utility model involved technical characteristic do not form conflict each other and just can mutually combine.
Motor vehicle seat back release mechanism of the prior art as shown in Figure 1, has done detailed introduction in the introduction, has repeated no more therewith.
A kind of motor vehicle seat back release mechanism as shown in Figure 2,3, comprises cushion skeleton 1, backrest frames 2, backrest adjustment skeleton 3, synchronizing bar centering rotating shaft cover 4, backrest regulating handle returning spring 5, backrest handle connector 6, backrest regulating handle 7, back regulator synchronizing bar 8.
Cushion skeleton 1 is welded with backrest frames 2, backrest frames 2 is bolted the side regulating skeleton 3 at backrest again, back regulator synchronizing bar 8 is laterally below backrest frames 2, a side of backrest frames 2 is passed until regulate skeleton 3 through backrest in one end of back regulator synchronizing bar 8, the other end of back regulator synchronizing bar 8 is rotatably connected to another side of backrest frames 2, namely backrest frames 2 with back regulator synchronizing bar 8 for axis of rotation.Key point of the present utility model is: regulate cover on one end of the back regulator synchronizing bar 8 of skeleton 3 to have synchronizing bar centering rotating shaft cover 4 through backrest, the outer peripheral edges cover of synchronizing bar centering rotating shaft cover 4 has backrest regulating handle returning spring 5, backrest regulating handle returning spring 5 is wind spring, synchronizing bar centering rotating shaft cover 4 is assemblied in the rotating shaft trepanning 6.1 of backrest handle connector 6, front end and the backrest of backrest regulating handle returning spring 5 regulate the outside panel beating of skeleton 3 (backrest regulates the outside panel beating of skeleton 3 to rotate) to be connected, the rear end of backrest regulating handle returning spring 5 connects with backrest handle connector 6 (backrest handle connector 6 can regulate skeleton 3 to rotate relative to backrest).The rotating shaft trepanning 6.1 of backrest handle connector 6 has outward extending extension 6.2, the periphery of extension 6.2 has some draw-in grooves 6.3, the middle part of backrest regulating handle 7 is provided with the projection 7.2 being inserted into extension 6.2, the periphery of protruding 7.2 is provided with the fastening strip 7.1 matched with some draw-in grooves 6.3, protruding 7.2 are inserted into the outward extending extension 6.2 of rotating shaft trepanning 6.1, fastening strip 7.1 snaps in draw-in groove 6.3, and backrest regulating handle 7 is fixedly connected on backrest handle connector 6.
Backrest regulating handle returning spring 5 is in tension time flat, rotating backrest regulating handle 7 when unlocked causes backrest handle connector 6 to rotate, backrest handle connector 6 allows synchronizing bar centering rotating shaft cover 4 rotate, and synchronizing bar centering rotating shaft cover 4 allows backrest adjustment skeleton 3 unlock thus makes backrest realize regulating.
Terminate when adjustment unlocks, recliner inner structure automatically stop, now because the reasons such as synchronism only rely on backrest to regulate skeleton 3 self can not locking completely, therefore, one end of backrest regulating handle returning spring 5 regulates owing to being stuck in backrest on the outside panel beating of skeleton 3, backrest handle will be forced to connect 6 resiliences, backrest is regulated skeleton 3 locking completely, substantially increase the safety that back of seat regulates; Synchronizing bar centering rotating shaft cover 4 is assemblied in the rotating shaft trepanning 6.1 of backrest handle connector 6, can ensure the squareness of backrest regulating handle 7 and back regulator synchronizing bar 8, thus ensure that the gap of backrest regulating handle and Plastic Parts side guard plate is even.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., be all included within protection domain of the present utility model.
