At this moment, the headrest 200 is allowable to move relative to the backrest portion 120 up and down. When the headrest 200 moves, since the adjusting members 520 are abutted against the headrest 200, the two adjusting members 520 are driven to move with headrest 200 simultaneously. During the above-mentioned process, the position of two shoulder straps 400 are immovable, but parts where the two shoulder straps 400 stretch out of the first through holes 522a are changed. When the headrest 200 moves to a desired position, the two shoulder straps 400 move to the corresponding positions simultaneously, such that the height of the two shoulder straps 400 match the height of the headrest 200. Afterward, the operating member 310 is released, such that the two resilient members 360 recover and drive the two engaging members 330 to protrude from the guiding member 340 and to insert into the corresponding engaging holes 352.

In contrast to the prior art, the end of each of the two shoulder straps of the child safety seat of the present invention, which wraps about the fixing member, passes through the first through hole of the adjusting member and stretches to the front side of the seat body. The ends of the two shoulder straps are coupled with the crotch strap so as to secure a child. Each of the two adjusting members is driven to adjust a height of the corresponding shoulder strap when a height of the headrest is adjusted. When the headrest is positioned at a desired height, the heights of the two shoulder straps match the height of the headrest, and it is not required to adjust the heights of the headrest and the shoulder straps repeatedly. Therefore, the shoulder strap adjusting mechanism has advantages of simple structure and easy operation, such that the child safety seat of the present invention can be adapted for children with different heights.

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. Caaln
