## Background
BACKGROUND OF THE INVENTION
Field of the Invention
The present invention relates to a direction setting device for the seat of a baby stroller and, more specifically, to a direction setting device for the seat of a baby stroller providing the function that the sunshade of the baby stroller may simultaneously change its direction after the direction of the seat of the baby stroller is changed.
Description of the Prior Art
It is more flexible to use a baby stroller if the direction of the backrest of the baby stroller is allowed to be changed to switch the riding direction of the baby on the stroller to allow the baby to face the pusher or not according to the users' requests.
The baby stroller disclosed in the prior art may only be operated to change its backrest direction, but the direction of its sunshade is not able to be changed after the backrest direction of the prior art is switched. That is, the sunshade arranged on the top of the prior art baby stroller for sun protection is not allowed to simultaneously change its direction after the seat direction of the prior art baby stroller is changed. Consequently, the sunshade of the prior art baby stroller will lose some of its sun-protective ability and weaken the effectiveness of sun protection. In order to enable the sunshade to change its direction, some stroller manufacturers suggest removing the whole sunshade apparatus from the frame and then re-assembling in the other direction, or interchanging the front and the rear ribs supporting the sunshade cloth by turning, or directly mounting another piece of sunshade apparatus in the other direction of the backrest.
The aforesaid mode disclosed in the prior art is inconvenient for the users, so that it needs to improve. Moreover, the angle of the backrest after being changed in direction is controlled by a plate mechanism for tilting the backrest according to the prior art, and to equip with such a plate mechanism for tilting the backrest may result in the product cost increasing. Thus, the prior art with the mentioned disadvantage also needs to be ameliorated.

DESCRIPTION OF THE PREFERRED EMBODIMENTS
The means for achieving the aforesaid objective and the functions of the present invention will become apparent from the following description, taken in connection with the accompanying drawings, wherein a preferred embodiment of the present invention is disclosed.
Referring to FIGS. 1 to 3, the baby stroller includes a frame 1, a seat 2 inside the frame 1, a main backrest 3, a footrest 4 arranged under the front end of the frame 1, and a sunshade 5 arranged at the top of the frame 1 and supported by a front sunshade rib 51 as well as a rear sunshade rib 52.
The side of the main backrest 3 facing the front end of the frame 1 is provided with an auxiliary backrest 6, which is a fabric cover stuffed with a supporting member and whose bottom end is sewed together with the seat fabric arranged on the frame 1 to form a sewing thread line 60. Thus, the auxiliary backrest 6 may move to the front end of the frame 1 via the sewing thread line 60 to change and set the direction of the seat.
The footrest 4 is adjustable to multiple elevation angles.
The sunshade 5 wraps on and between the front sunshade rib 51 and the rear sunshade rib 52. A rear canopy 53 has one side secured on the top surface of the sunshade 5 between the sunshade ribs 51 and 52. A switching line 531 forms at the joins of the rear canopy 53 and the sunshade 5. The other side of the rear canopy 53 is provided with a bottom end 530 hanging down, and the bottom end 530 is fastened to the outer surface of the top end of the auxiliary backrest 6 by a first fastening element 55 which may be a velcro strip. Moreover, the bilateral sides of the rear canopy 53 relating to and extending along the rear sunshade rib 52 are respectively provided with a slit 54 whose bilateral edges are fastened to each other by a second fastening element 56, such as a velcro strip.
FIGS. 4 to 13 show a sequence of movements how the direction of the baby stroller seat is changed. First, the second fastening element 56 on the slit 54 of each bilateral side of the rear canopy 53 needs to be pulled apart, and the first fastening element 55 on the hanging-down bottom end 530 of the rear canopy 53 also needs to be separated, as shown in FIG. 4. Next, the rear sunshade rib 52 needs to be held and the bottom end 530 of the rear canopy 53 needs to be grasped to turn over toward the top of the frame 1, as shown in FIGS. 5 and 6. Thus, the rear canopy 53 and the bottom end 530 of the rear canopy 53 are allowed to be turned over frontward to the front side of the frame 1 via the switching line 531. The front sunshade rib 51 and the rear sunshade rib 52 need moving toward the front side of the frame 1 to set its position, and, then, the second fastening element 56 on the slit 54 of the bilateral edges of the rear canopy 53 needs to be fastened together, as shown in FIG. 7 to FIG. 10. The auxiliary backrest 6 needs pivot turning and moving toward the front end of the frame 1 via the sewing thread line 60, as shown in FIG. 11 to FIG. 13. Further, the footrest 4 needs to be adjusted up to support the auxiliary backrest 6. The first fastening element 55 of the auxiliary backrest 6 needs to fasten to a third fastening element 57, such as a velcro strip, arranged on the bottom end of the footrest 4. The bottom end 530 of the rear canopy 53 also needs to be fastened to the bottom end of the footrest 4 and to the auxiliary backrest 6 simultaneously to allow the auxiliary backrest 6, the footrest 4 and the bottom end 530 to be fastened together. Consequently, the rear canopy 53 and the footrest 4 may support and hold the auxiliary backrest 6 to allow the baby to lean against after the direction of the seat on the baby stroller is changed, as shown in FIGS. 14 and 15. Thus, the direction changing and setting disclosed in the present invention is completed.
