Frame 1 is hinged by shaft and seat support 2 and chairback brace 3 respectively, torsional spring is arranged in shaft, lockable mechanism 11 is installed in seat
On chair holder 2, for realizing the expansion locking to seat, link mechanism is connect with seat support 2 and chairback brace 3 respectively, can
The both ends of swivel link 8 are connect with lockable mechanism 11 and link mechanism respectively, after rotatable connecting rod 8 is for realizing seat is folded
Rotation dig, seat fold rotation dig after, occupy little space.
Further, link mechanism includes fixed link 12 and swing rod 10, and fixed link 12 is set on chairback brace 3 (fixed
Bar 12 is set in the shaft of chairback brace 3), swing rod 10, which is equipped with, determines shaft, determines shaft and installs in cushion bracket 1, swing rod
10 can determine to rotate centered on shaft, and the both ends of swing rod 10 are hinged by axis pin and fixed link 12 and rotatable connecting rod 8 respectively, can
Swivel link 8 is equipped with pin hole 13, is connect with swing rod 10 by pin hole 13 and axis pin；
Lockable mechanism 11 includes lock 4, block 5, sliding block 6, connecting rod 7 and sliding rail 9, and lock is fixed in cushion bracket 1, is kept off
Block 5 is set on sliding block 6, and sliding rail 9 is fixedly arranged on seat support 2, and sliding block 6 is set on sliding rail 9, and sliding block 6 can be moved along sliding rail 9
Dynamic, the connection of sliding block 6 and one end of connecting rod 7, rotatable connecting rod 8 and the other end of connecting rod 7 are hinged, and rotatable connecting rod 8 passes through spiral shell
Bolt is fastened with the locking of connecting rod 7.
Further, rotatable connecting rod 8 is nested in the other end of connecting rod 7, and rotatable connecting rod 8 is locked by bolt and connecting rod 7
It is tightly solid, it is nested with rotatable connecting rod 8 for connecting rod 7 by this bolt.
Further, the installation site of sliding rail 9, connecting rod 7 and rotatable connecting rod 8 is conllinear with the shaft on seat support 2；It protects
When card cushion bracket 1 and 3 entirety of chairback brace are rotated around seat support 2, link mechanism will not be interfered.
Further, block 5 is hinged by hinged shaft and sliding block 6, and torsional spring is arranged on hinged shaft；Make block 5 that can only unidirectionally turn
Dynamic, when seat is unfolded, the lock 4 of seat bottom jacks up block 5, and after being laid flat seat, block 5 rebounds simultaneously automatically under the effect of torsion spring
Into lock, the locking to seat is realized.
Further, one end of connecting rod 7 is equipped with the first sliding groove, and sliding block 6 is set to by bolt lock fastening in the first sliding groove,
Adjustment can be moved along the first sliding groove by unclamping bolt rear slider 6；There is sliding slot on connecting rod 7, when backrest is unfolded, there is one section of null
Journey, when the chair back is deployed into certain angle, connecting rod 7 pulls sliding block 6, and the block being connected on sliding block 65 is made to be detached from lock 4；It realizes
The positioning of multiple angles after seat is unfolded.
Further, the both ends of swing rod 10 are equipped with second sliding slot, and axis pin is set in second sliding slot, and axis pin can be along second
Sliding slot moves；Ensure that rotatable connecting rod 8 moves in the horizontal direction, will not interfere with the rotation of chairback brace 3.

Prevent upper boom from being rotated with lower beam, upper boom and lower beam can relatively rotate after bolt unclamps.
As shown in Figure 7 and Figure 8, the state when foldable seat of car mechanism deploying that solid line expression automatically resets in Fig. 7, it is empty
Line indicates the state when foldable seat of car mechanism to automatically reset folds；Solid line indicates lockable mechanism 11 and connecting rod machine in Fig. 8
The position of structure in the unlocked state, dotted line indicate the position of lockable mechanism 11 and link mechanism in a latched condition, automatically reset
The use process of foldable seat of car mechanism include the following steps：
1) user is laid flat cushion bracket 1 and back bracket manually, at this point, swing rod 10 turns to vertical direction, block 5 into
Enter U-shape lock button 4 and cushion bracket 1 is locked in horizontal position.
2) backrest is unfolded in user manually, and the fixed link 12 on chairback brace 3 makes swing rod 10 rotate, and connects with swing rod 10
The rotatable connecting rod 8 connect pulls connecting rod 7 to move backward, but mobile distance is no more than the length of 7 upper hopper chute of connecting rod, and seat is leaned on
The back of the body is fixed to the angle for accommodating seating with other mechanisms, and lock 4 and block 5 still lock cushion bracket 1 at this time.
3) need seat automatically reset folding when, user releases the fixation of backrest manually, and is leaned on to pusher seat
The back of the body makes the expanded angle of backrest increase, and swing rod 10 is made to be rotated further, to allow the displacement distance of connecting rod 7 to be more than 7 upper hopper chute of connecting rod
Length, the beginning of sliding block 6 at this time moves backward along sliding rail 9, block 5 pulled out U-shape lock button 4, cushion bracket 1 is made to unlock.
4) make chairback brace 3 and cushion bracket collapse automatically under the action of torsional spring after unlocking to reset, because of cushion bracket 1
The elastic force of torsional spring is less than the elastic force of torsional spring between cushion bracket 1 and chairback brace 3 between seat support 2, so back bracket
First close up, seat support is packed up again.
Above is only presently preferred embodiments of the present invention, and of course, the scope of rights of the present invention cannot be limited by this,
Therefore according to equivalence changes made by scope of the present invention patent, still belong to protection scope of the present invention.
