The infant carrier apparatus according to claim 1, wherein the first position is adjacent to the rear end or the front end of the seat assembly. 3. The infant carrier apparatus according to claim 1, wherein the first and second positions are respectively adjacent to the front and rear ends of the seat assembly, or vice-versa. 4. The infant carrier apparatus according to claim 1, wherein the support frame further includes at least a guide rail, and the holder socket is movable along the guide rail substantially parallel to the longitudinal axis. 5. The infant carrier apparatus according to claim 4, wherein the guide rail is affixed at one side of the seat assembly. 6. The infant carrier apparatus according to claim 1, wherein the restraint element includes a resilient arm, the resilient arm being biased to engage with the holder socket when the holder socket is in the first position. 7. The infant carrier apparatus according to claim 6, wherein the support frame further includes a guide rail along which the holder socket is movable for adjustment between the first and second position, and the resilient arm has a distal end that protrudes through an opening of the guide rail to engage with the holder socket for blocking displacement of the holder socket from the first position toward the second position. 8. The infant carrier apparatus according to claim 6, wherein while the holder socket is in the first position, the release actuator portion is operable to cause deflection of the resilient arm to disengage the resilient arm from the holder socket. 9. The infant carrier apparatus according to claim 6, wherein the restraint element further includes an angled surface, the holder socket moving toward the first position is adapted to come into contact with the angled surface to cause deflection of the resilient arm toward an unlocked position. 10. The infant carrier apparatus according to claim 1, wherein the backrest frame is pivotally connected with the holder socket about a pivot axis and has an end portion provided with a latch element, and the holder socket includes a plurality of locking grooves disposed at different radial directions relative to the pivot axis and adapted to receive the engagement of the latch element to hold the backrest frame at different inclinations. 11. A method of adjusting a backrest assembly of an infant carrier apparatus, wherein the infant carrier apparatus includes a support frame having a seat assembly, a backrest frame, and at least a holder socket that is assembled with the backrest frame and the support frame and has a first and a second release actuator, the support frame further including a first and a second restraint element that are arranged at two fixed locations spaced apart from each other on the support frame, the first and second restraint elements being respectively operable to retain the holder socket in a first and a second position spaced apart from each other, the method comprising: while the holder socket is in the first position, causing the first restraint element to engage with the holder socket to block displacement of the holder socket toward the second position;while the holder socket is in the first position, depressing the first release actuator so as to cause displacement of the first restraint element for disengaging the first restraint element from the holder socket;moving the holder socket from the first position toward the second position, wherein the first and second release actuators move in unison with the holder socket relative to the support frame;while the holder socket is in the second position, causing the second restraint element to engage with the holder socket to block displacement of the holder socket from the second position toward the first position;while the holder socket is in the second position, depressing the second release actuator to cause displacement of the second restraint element for disengaging the second restraint element from the holder socket; andmoving the holder socket from the second position toward the first position. 12. The method according to claim 11, wherein the step of moving the holder socket from the first position toward the second position comprises causing the holder socket to slide along a guide rail. 13. The method according to claim 11, wherein any of the first and second restraint elements is a unidirectional restraint element. 14. The method according to claim 11, wherein the backrest frame is pivotally connected with the holder socket about a pivot axis and has an end portion provided with a latch element, and the holder socket includes a plurality of locking grooves that are disposed at different radial directions relative to the pivot axis and are adapted to receive the engagement of the latch element to hold the backrest frame at different inclinations. 15. An infant carrier apparatus comprising: a support frame, including a seat assembly that has a longitudinal axis extending from a front end to a rear end thereof, and a first and a second restraint element arranged at two spaced-apart fixed locations on the support frame along the longitudinal axis; anda backrest assembly, including a backrest frame and at least a holder socket, the holder socket being respectively assembled with the backrest frame and the support frame, the holder socket including a first and a second release actuator and being adjustable between a first position and a second position along the longitudinal axis, the holder socket and the first and second release actuators being movable in unison along with the backrest frame relative to the support frame;wherein the first restraint element is operable to engage with the holder socket when the holder socket is in the first position to block displacement of the holder socket from the first position toward the second position, the first release actuator is operable to push against the first restraint element so that the first restraint element moves to disengage from the holder socket for allowing displacement of the holder socket from the first position toward the second position, the second restraint element is operable to engage with the holder socket when the holder socket is in the second position to block displacement of the holder socket from the second position toward the first position, and the second release actuator is operable to push against the second restraint element so that the second restraint element moves to disengage from the holder socket for allowing displacement of the holder socket from the second position toward the first position. 16. The infant carrier apparatus according to claim 15, wherein the first and second positions are respectively adjacent to the front and rear ends of the seat assembly, or vice-versa. 17. The infant carrier apparatus according to claim 15, wherein the support frame further includes at least a guide rail, and the holder socket is movable along the guide rail. 18. The infant carrier apparatus according to claim 15, wherein the first and second restraint element respectively include a first and a second resilient arm, the first resilient arm being biased to engage with the holder socket when the holder socket is in the first position, and the second resilient arm being biased to engage with the holder socket when the holder socket is in the second position. 19.
