A child vehicle seat includes two anchored members secured on a rear side of a back support portion of a seat body and respectively having positioning units, a belt support member movable uprightly relative to the anchored members and having a belt guiding opening, two locking members movable longitudinally relative to the belt support member to engage or disengage two of the positioning units, an actuator movable transversely relative to the belt support member, and a coupling member for transmitting movement of the actuator to the locking members, thereby moving simultaneously the locking members to an unlocking position, where the belt support member is movable uprightly. A belt passes through the belt guiding opening so that movement of the belt support member can permit change of height position of the belt.

1. A child vehicle seat comprising:a seat body adapted to be coupled to a vehicle seat, and including a bottom seat portion and a back support portion extending in an upright direction from said bottom seat portion, said back support portion having front and rear sides opposite to each other, and a belt receiving opening which extends from said front side through said rear side;right and left anchored members secured on said rear side and outboard to said belt receiving opening in a longitudinal direction transverse to the upright direction, each of said right and left anchored members having a plurality of positioning units which are displaced from one another in the upright direction;a belt support member disposed rearwardly of said back support portion, and movable relative to said right and left anchored members in the upright direction, said belt support member having a belt guiding opening which is communicated with said belt receiving opening;right and left locking members disposed to be movable relative to said belt guiding opening in the longitudinal direction, each of said right and left locking members having a key end and a positioning end which is opposite to said key end in the longitudinal direction and which is movable relative to a respective one of said right and left anchored members between a locking position, where said positioning end engages one of said positioning units so as to lock movement of said belt support member relative to said right and left anchored members, and an unlocking position, where said positioning end disengages from said one of said positioning units so as to permit movement of said belt support member relative to said right and left anchored members in the upright direction;an actuator disposed to be movable relative to said belt support member and relative to said key ends of said right and left locking members in a transverse direction relative to the longitudinal direction between first and second positions;a coupling member disposed to couple said actuator to said key ends of said right and left locking members such that when said actuator is moved from the first position to the second position, said positioning ends of said right and left locking members move simultaneously from the locking position to the unlocking position so as to permit movement of said belt support member in the upright direction relative to said right and left anchored members; anda belt including a top belt end which is disposed in said belt guiding opening, and a shoulder belt segment which extends from said top belt end forwardly to said front side of said back support portion through said belt receiving opening and which extends downwardly toward said bottom seat portion such that said shoulder belt segment is pullable to move in or out of said belt receiving opening when said top belt end is moved with said belt support member in the upright direction. 2. The child vehicle seat of claim 1, further comprising a biasing member disposed to bias said actuator toward the first position. 3. The child vehicle seat of claim 2, wherein each of said right and left anchored members is an elongated shaft which is secured to said rear side of said back support portion, each of said positioning units being configured to be a positioning slot for retaining a corresponding one of said positioning ends of said right and left locking members therein. 4. The child vehicle seat of claim 3, wherein said coupling member includesright and left keyways which are formed in said actuator, and which are spaced apart from each other in the longitudinal direction, each of said right and left keyways having proximate and distal ends respectively proximate to and distal from said key end of a respective one of said right and left locking members, said distal ends of said right and left keyways extending from said proximate ends, respectively, towards each other and in the transverse direction,right and left keys which are respe ctively secured to said key ends of said right and left locking members and which extend in the upright direction to be received in and to be slidable along said right and left keyways such that, when said actuator is moved from the first position to the second position, said right and left keys respectively slide from said proximate ends towards said distal ends so as to move said positioning ends of said right and left locking members from the locking position to the unlocking position. 5. The child vehicle seat of claim 4, wherein said belt support member has right and left sleeve ends which are disposed outboard to said belt guiding opening and which are sleeved on and which are slidable along said right and left anchored members, said positioning end of each of said right and left locking members extending radially into a respective one of said right and left sleeve ends so as to be retained in a corresponding one of said positioning slots, thereby preventing said right and left sleeve ends from moving relative to said right and left anchored members, respectively. 6. The child vehicle seat of claim 5, further comprising right and left blocking members which are disposed on said right and left anchored members, respectively, to limit an extent of movement of said right and left sleeve ends of said belt support member when said positioning ends are in the unlocking position. 7. The child vehicle seat of claim 1, wherein said belt receiving opening includes two elongated slots which are elongated in the upright direction and which are spaced apart from each other in the longitudinal direction, said belt guiding opening including two access holes which are respectively communicated with and which are aligned with said elongated slots, said top belt end of said belt including two top belt end portions which are respectively disposed in said access holes, said shoulder belt segment including two shoulder belt portions which extend from said top belt end portions forwardly to said front side of said back support portion through said elongated slots, respectively.
