At this time, the second locking member 266 locks the footrest 264 to the backrest 262. 15, the second locking member 26 is locked in the second deployed position relative to the second locking member 26. When the support base 260 is in the locked position, the stop 2604 of the support base 260 engages the second locking member 2602. The second engaging portion 2662a of the footrest 266 is stopped, and the footrest 264 is rotated in the direction of the arrow A5. Therefore, the footrest 264 is in the second deployed position. The position is kept constant.

[0049] When the user desires to fold the seat 26, the user may fold the footrest 26 shown in FIG. 264 can be rotated in the direction of arrow A6 relative to the backrest 262. When the footrest 264 rotates relative to the backrest 262, the footrest 264 engages the second locking member. 266 is driven to release the lock, and the footrest 264 is moved relative to the backrest 262 as shown in FIG. 4 to the second folded position shown in FIG. The rest 264 is extended from the second extended position shown in FIG. 13 in the direction of arrow A relative to the backrest 262. 17, when the second locking member 266 is rotated in the direction of the arrow 6, the second locking member 266 is The support base 260 rotates in the direction of arrow A6 together with the support base 264. The inclined drive surface 2602 presses the second engagement portion 2662b of the second locking member 266. As a result, the second locking member 266 moves in the direction of the double arrow A3 toward the footrest 264. The second locking member 2 then moves to drive the second locking member 2 and release the lock. 66 is fully inserted into the receiving recess 2642 of the footrest 264, and the lock shown in FIG. 14. The footrest 264 is in the release position, whereby the footrest 264 is in the position shown in FIG. The footrest 264 can then be rotated to a second folded position as shown in FIG. By rotating, the seat 26 can be quickly folded and is simple in structure. It is also convenient to operate.

[0050] As shown in FIG. 19, the footrest 264 rotates to drive the second locking member 266. When the lock is released, the second locking member 266 moves toward the footrest 264. , compressing the third elastic member 268. When the user wishes to unfold the sheet 26, the user The footrest 264 can be rotated relative to the backrest 262 in the direction of arrow A5 shown in FIG. The footrest 264 may be folded relative to the backrest 262 in the second folding position shown in FIG. 19 to the second deployed position shown in FIG. 13. The elastic force generated by the second locking member 266 moves toward the support base 260. 262. The footrest 264 is driven back to lock the footrest 264 in the second extended position relative to the backrest 262. Click.

[0051] As shown in FIGS. 12-14 and 20, the seat 26 pivots to the footrest 264. The arm bar 270 may further be provided so as to be movably connected thereto. 70 can also be rotated to fold and unfold relative to the backrest 262. Preferably, the arm bar 270 is in a position where it can be moved when the arm bar 270 is not in use. a removable and pivotable footrest 264 so that it can be removed from the seat 26; As shown in FIG. 21, the footrest 264 includes a guide groove 2646. The arm bar 270 may include a guide pillar 2700. When the footrest 264 is pivotally connected to the footrest 264, the guide pillar 2700 is guided by the guide groove 2 646. Thus, the footrest 264 is folded relative to the backrest 262. When the footrest 264 is rotated to be folded or unfolded, the end of the guide groove 2646 of the footrest 264 Push the guide pillar 2700 of the arm bar 270 to move the arm bar against the backrest 262. -270 to fold or unfold.

[0052] As described above, the tension member pulls the rotating member as long as the user pulls the unlocking member. The first locking member is driven to rotate and push the first locking member toward the second fixing member. At this time, the handle, rear legs, and front legs rotate relative to each other. The present disclosure relates to a lock release member, a first lock member, a rotating member, and The folding mechanism of the stroller is formed by using the pulley and tension member, which is not only simple in structure but also It is convenient to operate, thereby further reducing the manufacturing cost of the stroller. As long as you rotate the footrest, the seat will fold or unfold accordingly. The second locking member cooperates with the second inclined drive surface of the support base to The cart can be quickly folded by rotating the footrest, and the structure is simple. In addition, it is easy to operate. In this case, the user rotates the footrest to fold the armbars in synchronization. The seat of the present disclosure does not need to have a separate folding mechanism. This further reduces the manufacturing costs of the seat and stroller.
