The present invention also has the following embodiments in addition to the above:
in a further embodiment of the present invention, as shown in fig. 1 to 6, the lower portion of the rotating plate 18 is provided with a convex hull 53, and the convex hull 53 is constantly in contact with the wire connecting plate 19 when the rotating plate 18 rotates. When the rotating plate 18 is pushed by the backrest to rotate clockwise, the rotating plate 18 will force the wire connecting plate 19 to rotate clockwise synchronously. Clockwise rotation of the wire attachment plate 19 pulls the second wire 27.
In a further embodiment of the present invention, referring to fig. 4, when one end of the second pulling wire 27 is pulled by the pulling wire connecting plate 19, the other end of the second pulling wire 27 rotates the slide rail unlocking handle 15 counterclockwise by pulling the second pulling wire bracket 33 fixed on the slide rail unlocking handle 15, so as to unlock the slide rail 14. The simultaneous unlocking of the backrest and the slide rail 14 enables the seat state to be quickly adjusted, so that the space volume of the seat is smaller, and more space is reserved for a user to conveniently enter a rear seat.
In a further embodiment of the present invention, the slide rail 14 is provided with a first wire support 31, and the other end of the second wire 27 penetrates the first wire support 31.
In a further embodiment of the present invention, the slide rail unlocking handle 15 is provided with a second wire support 33, and the other end of the second wire 27 is connected to the second wire support 33.
In a further embodiment of the invention, the end of the shaft 23 is square and the fourth hole 37 is a key-like hole. When the backrest frame 3 is unlocked by the recliner unlocking handle 47, the recliner synchronous connecting shaft 38 rotates counterclockwise while driving the rotation shaft 23 to rotate, which does not cause the recliner unlocking bracket 17 to change its state.
In a further embodiment of the present invention, the one-way mechanism 44 comprises: and a torsion spring 50, one end of the torsion spring 50 being in contact with the groove on the outboard seat attachment plate 28.
In a further embodiment of the present invention, the one-way mechanism 44 comprises: the handle mounting plate 49, the other end of the torsion spring 50 contacts with the handle mounting plate 49, and the handle mounting plate 49 is provided with a three-handle mounting plate lug.
In a further embodiment of the present invention, the one-way mechanism 44 comprises: the joint 51, the joint 51 has three joint grooves, and each handle mounting plate projection contacts with the upper edge of one joint groove.
In a further embodiment of the present invention, the one-way mechanism 44 further comprises: a recliner unlocking handle 47, the recliner unlocking handle 47 being mounted to a handle mounting plate 49 by an unlocking handle screw 46.
In a further embodiment of the present invention, the one-way mechanism 44 further comprises: a second clip 48 is also provided between the second clip 48, the recliner release handle 47 and the handle mount plate 49.
In a further embodiment of the invention, a force limiting mechanism 32 is further provided in the middle of the second wire 27.
In a further embodiment of the present invention, please refer to fig. 1, fig. 3, and fig. 4, when the quick entry function is used, the locking handle 4 is locked, and the initial state of the quick entry mechanism is as shown in fig. 3, when the locking handle 4 pulls the angle adjuster unlocking bracket 17 to rotate counterclockwise by the first pull wire 26, a cam structure is formed at a place where the upper part of the angle adjuster unlocking bracket 17 contacts with the bent part of the rotating plate 18, when the angle adjuster unlocking bracket 17 rotates counterclockwise, the rotating plate 18 is forced to move upward, and when the angle adjuster unlocking bracket 17 rotates a certain angle, the rotating plate 18 rises to the highest position; meanwhile, in the rotating process, the rotating shaft 23 can synchronously rotate through a special hole in the angle adjuster unlocking support 17, so that the backrest framework 3 is unlocked by rotating the angle adjuster synchronous connecting shaft 38; after the angle adjuster unlocking support 17 rotates anticlockwise to a certain angle, the locking clamping plate 21 falls clockwise under the pulling of the first tension spring 20 to clamp the angle adjuster unlocking support 17, so that the angle adjuster unlocking support 17 is blocked from freely returning, and the backrest framework 3 is ensured to be always in an unlocked state in the using process. When the recliner 7 is unlocked and the rotating plate 18 is lifted to the highest position, the recliner limit bracket 17 will contact the rotating plate 18 at a specific position when the backrest is laid down, and then the rotating plate 18 is driven to rotate synchronously until the backrest rotates to the foremost position.
In a further embodiment of the present invention, referring to fig. 3, when the seat needs to be returned to the use position after the quick entry function is completed, the backrest frame 3 is pushed after the slide rail 14 is pushed backward to the locking position, when the backrest frame 3 is pushed to the setting position, the backrest limit stop point 43 will contact with the front end of the locking catch plate 21, and then the locking catch plate 21 will be pushed by the backrest limit stop point 43 to rotate counterclockwise around the rivet 29. After the angle adjuster unlocking support 17 is rotated by a certain angle, the locking clamping plate 21 releases the angle adjuster unlocking support 17, and after the angle adjuster unlocking support 17 returns, the angle adjuster 7 enters a locking state, and the backrest framework 3 is locked to a preset position.
In a further embodiment of the present invention, when the recliner unlocking handle 47 rotates counterclockwise to unlock the backrest frame 3, the handle mounting plate 49 drives the engaging member 51 to rotate counterclockwise together, thereby driving the recliner synchronization connecting shaft 38 to rotate to unlock the recliner 7. When the recliner 7 is unlocked using the quick entry function by the catcher 4 located at the shoulder, the recliner synchronizing connecting shaft 38 drives the engagement member 51 to rotate, but under the action of the torsion spring 50, the upper edge of the projection of the handle mounting plate 49 is gradually disengaged from the upper edge of the corresponding groove on the engagement member 51, so that the counterclockwise rotation of the recliner synchronizing connecting shaft 38 does not cause the synchronized rotation of the recliner unlocking handle 47.
While the invention has been described with reference to a preferred embodiment, it will be understood by those skilled in the art that various changes in form and detail may be made therein without departing from the spirit and scope of the invention.
