As shown in fig. 1 to 8, the portable seating system for the automobile seat comprises a base plate 14, a rotating plate 2 rotatably connected with the base plate 14 through a recliner 1 and a slide rail unlocking rocker arm 4 for unlocking a seat slide rail, wherein the rotating plate 2 has a seating position (shown in fig. 1 and 2), a slide rail unlocking starting position (shown in fig. 3 and 4), a slide rail unlocking completion position (shown in fig. 5 and 6) and a backrest flat position (shown in fig. 7 and 8), a seat backrest unlocking mechanism, a seat slide rail unlocking mechanism and a limit pulling piece 12 are arranged on the base plate 14, and the limit pulling piece 12 has a backrest unlocking position (shown in fig. 8), an initial position (shown in fig. 2) and a slide rail unlocking position (shown in fig. 6).
When the seat back unlocking mechanism is operated, the angle adjuster 1 is unlocked, the limiting poking piece 12 rotates from the initial position to the back unlocking position, and the rotating plate 2 can rotate between the riding position and the back flat position; when the seat slide rail unlocking mechanism is operated, the angle adjuster 1 is unlocked, the rotating plate 2 can rotate between a riding position and a slide rail unlocking completion position, wherein when the rotating plate 2 rotates from the slide rail unlocking starting position to the slide rail unlocking completion position, the limiting poking piece 12 can rotate from the initial position to the slide rail unlocking position under the drive of the rotating plate 2, so that the slide rail unlocking rocker 4 rotates to unlock the seat slide rail.
It should be noted that when the recliner 1 is locked, the rotating plate 2 and the base plate 14 cannot be rotated relatively, the relative position is locked, and when the recliner 1 is unlocked, the rotating plate 2 and the base plate 14 can be rotated relatively.
Referring to fig. 1, 2, 7 and 8, the seat back unlocking mechanism includes a recliner unlocking head 11, a recliner unlocking link 13, an execution link set and a manipulation link set. The angle adjuster unlocking end 11 is used for unlocking the angle adjuster 1, the execution connecting rod group is used for driving the limiting shifting plate 12, the angle adjuster unlocking connecting rod 13 is used for driving the execution connecting rod group, and the operation connecting rod group is used for driving the angle adjuster unlocking connecting rod 13.
The angle adjuster unlocking end 11 is connected with the angle adjuster 1 through welding, and the angle adjuster 1 can be locked and unlocked by rotating the angle adjuster unlocking end 11, and the angle adjuster unlocking end 11 has a trend of elastic reset (the angle adjuster 1 is internally provided with a reset spring), namely the angle adjuster unlocking end 11 has a trend of elastic reset. The limiting poking piece 12 is rotatably arranged on the base plate 14, when the limiting poking piece 12 is located at the initial position, the limiting poking piece 12 can interfere with the rotation of the rotating plate 2, so that the seat back can rotate by a certain angle and cannot be leveled, and when the limiting poking piece 12 rotates to the back unlocking position, the limiting poking piece 12 is used for yielding the rotating plate 2, so that the rotating plate 2 can rotate by a larger angle relative to the base plate 14, and the seat back can be leveled.
Referring to fig. 9, the shaft portion 111 of the recliner unlocking tip 11 includes two arcuate segments 111a and two inner cut segments 111b, and the two arcuate segments 111a and the two inner cut segments 111b are disposed in a pair by pair. And, the maximum aperture of the inscribed section 111b is smaller than that of the arc-shaped section 111 a. Further, the inner section 111b is a planar structure to facilitate the design of the steering assembly.

When the angle adjuster unlocking connecting rod 13 rotates, the angle adjuster unlocking end 11 synchronously rotates, the limiting poking piece 12 rotates from the initial position to the backrest unlocking position, and the backrest can rotate within a larger angle range until the backrest is put flat; when only the angle adjuster unlock end 11 is used, the angle adjuster unlock connecting rod 13 and the limit pulling piece 12 are not moved, the rotating plate 2 can rotate between the riding position and the slide rail unlock starting position, and when the rotating plate rotates to the slide rail unlock starting position, the limit pulling piece 12 can be driven to rotate from the initial position to the slide rail unlock position.
Specifically, the functional hole 131 includes two arc segments 131a and two protruding segments 131b that are disposed in two opposite directions, the maximum aperture of the protruding segments 131b is smaller than the aperture of the arc segment 131a, each protruding segment 131b has at least one interference point, and the length of the arc segment 111a is smaller than that of the arc segment 131a, and since the length of the arc segment 111a is smaller than that of the arc segment 131a, the shaft 111 of the recliner unlocking tip 11 can rotate in the functional hole 131 of the recliner unlocking link 13 at a certain angle to idle, i.e. the recliner unlocking tip 11 rotates without driving the recliner unlocking link 13 to rotate. Referring to fig. 12, when the recliner unlocking head 11 rotates clockwise from the locked position to the unlocked position, the recliner unlocking link 13 is not driven to rotate. Referring to fig. 11, due to the protruding section 131b, when the recliner unlocking link 13 rotates clockwise from the locked position to the unlocked position, the recliner unlocking end 11 can be driven to rotate clockwise from the locked position to the unlocked position.
Further, in order to make the outer peripheral surface of the shaft portion 11 of the unlocking end 11 of the angle adjuster and the inner wall of the functional hole 131 of the unlocking connecting rod 13 of the angle adjuster better in fitting degree, the following design is made, namely, the matching of the outer peripheral surface and the inner wall is more stable and reliable, and abnormal sound can be prevented: the curvature of the arc section 111a is equal to that of the arc section 131a, the protruding section 131b is of a V-shaped plane structure which is matched with the inner cutting section 111b, so that the functional hole 131 of the angle adjuster unlocking connecting rod 13 is of a butterfly-shaped structure, two planes of the whole protruding section 131b which are in a V shape are interference surfaces which are matched with the inner cutting section 111b, and when the shaft part 11 is abutted with the functional hole 131, the two inner cutting sections 111b of the shaft part 11 are respectively in surface contact with one protruding section 131b, the reliability is good, the abrasion is small, and the service life is long.
