The engaging component 11 is coupled to the resilient component 14 via the pivoting component 15, so that the engaging component 11 is disposed on the front end of the seat 30 for easy operation.
The pivoting component 15 facilitates the disposal of the engaging compoiieiiL 11 and Lhe resilieiiL compoiieiib 14.
Preferably, the first driving component 131 is engaged with the second driving component 112 between a pivoting point of the pivoting portion 13b and the seat 30 and a pivoting point of the pivoting component 15 and the seat 30 along the back-and-forth direction of the supporting base 20. Thus the operation of the operating component 13 for driving the engaging component can be simplified.
The operation of the child safety seat 100 of the present invention is introduced in detail as follows and illustrated with the figures. Please refer to FIG. 6a to FIG. 7c. FIG. 7a to FIG. 7c are lateral diagrams of the child safety seat disposed on a car seat 200 as the angle of the backrest 31 relative to the supporting base 20 is adjusted to different angles according to the embodiment of the present invention.
When the child safety seat 100 is disposed on the car seat as shown in FIG. 7a, the stepping engaging portion 111 of the engaging component 11 of the seat angle adjusting mechanism 10, which is closest to the pivoting component 15, is engaged with the fixing component 12 on the front end of the supporting base 20. The backrest 31 is at a smallest angle relative to the supporting base 20 for satisfying a user. As the child safety seat 100 is adjusted from a status shown in FIG. 7a to a status shown in FIG. 7b, the operating component 13 is rotated in a clockwise direction 01 so that the operating component 13 is pivoted around the pivoting portion 13b. The first driving portion 131 is engaged with the second driving portion 112, so that the rotating operating component 13 drives the engaging component 11 to pivot around the connecting component 15 in a counterclockwise direction 02, so as to detach the engaging component 11 from the fixing component 12. simultaneously, the seat 30 can be pulled in a direction far away from a backrest of the car seat 200 so that the seat 30 is pivoted around a hinge 91, as shown in FIG. 7b. And then, the operating component 13 can be released to be pivoted in the counterclockwise direction 02 by a recovering force provided by the resilient component 14, so Ohab Ohe operaLiiig comporienb 13 drives Ohe engaging componeiib 11 to recover in the clockwise direction Cl so as to contact against the fixing component 12 on the front end of the supporting base 20, by cooperation of the first driving component 131 and the second driving component 112. At this time, if the stepping engaging portion 111 at a central portion of the engaging component 11 is aligned to the fixing component 12, the engaging component 11 can be locked on the fixing component 12. If the stepping engaging portion 111 at the central portion of the engaging component 11 is not aligned to the fixing component 12, the operating component 13 should be pulled along the clockwise direction Cl until the stepping engaging portion 111 at the central portion of the engaging component 11 is locked on the fixing component 12. Thus the backrest 31 is at a middle angle relative to the supporting base 20, as shown in FIG. 6a and FIG. 7b.
As the child safety seat 100 is adjusted from the status shown in FIG. 7b to a status shown in FIG. 7c, the operating component 13 is rotated in the clockwise direction Cl so that the operating component 13 is pivoted to the pivoting portion 13b. The first driving portion 131 is engaged with the seoond driving portion 112, so that the rotating operating component 13 drives the engaging component 11 to pivot around the connecting component 15 in the counterclockwise direction C2, so as to detach the engaging component 11 from the fixing component 12, by cooperation of the first driving component 131 and the second driving component 112. Simultaneously, the seat 30 can be pulled in the direction far away from the backrest of the car seat 200 so that the seat 30 is pivoted around the hinge P1, as shown in FIG. 7c. And then, the operating component 13 can be released to be pivoted in the counterclockwise direction 32 by the recovering force provided by the resilient conponent 14, and the operating component 13 drives the engaging component 11 to recover in the clockwise direction Cl so as to contact against the fixing component 12 on the front end of the supporting base 20, by cooperation of the first driving component 131 and the second driving compoiierib 112. AL Ihis Lime, if LJie sLeppiiig engaging portion 111 of the engaging component 11 far away from the pivoting component 15 is aligned to the fixing component 12, the engaging component 11 can be locked on the fixing component 12. If the stepping engaging portion 111 of the engaging component 11 far away from the pivoting component 15 is not aligned to the fixing component 12, the operating component 13 should be pulled along the clockwise direction Cl until the stepping engaging portion 111 of the engaging component 11 far away from the pivoting component 15 is locked on the fixing component 12. Thus the backrest 31 is at a largest angle relative to the supporting base 20, as shown in FIG. 6c and FIG. 7c.
In contrast to the prior art, the fixing component is disposed on one of the seat and the supporting base transversely. An end of the engaging component is pivoted to the other one of the seat and the supporting base, and the other end of the engaging component is selectively engaged with the fixing component in different positions. The seat is movably connected to the supporting base in a back-and-forth direction along the supporting base, and an angle of the backrest of the seat relative to the supporting base can be adjusted conveniently. Besides, the structure of the seat angle adjusting mechanism is simplified in the present invention. Therefore, the child safety seat therewith also facilitates the adjustment of the angle of the backrest of the seat relative to the supporting base.
Those skilled in the art will readily observe that numerous modifications and alterations of the device and method may be made while retaining the teachings of the invention.
Accordingly, the above disclosure should be construed as limited only by the metes and bounds of the appended claims.
