2) it draws forward or pushes chair body backward；
3) angular adjustment knob is unclamped, under the pulling force of tension spring, angular adjustment knob can do homing action, there is two at this time
Kind situation, the first situation do homing action for angular adjustment knob and angular adjustment pin are driven just to be inserted into adjustment hole, make bone
Frame bent beam is fixed in chair body fixing seat；Second situation be angular adjustment knob do homing action drive angular adjustment pin without
Method is inserted into adjustment hole, is needed front and back slightly front and back micro-shifting chair body at this time, is inserted into angular adjustment pin in adjustment hole, completes chair
Body angle angle modulation；
(3) shoulder belt adjusts fixed and quick-disassembly structure application method:
1) fixing means: the first shoulder belt axis regulating part and the second shoulder belt axis regulating part are snapped into corresponding on headrest pulling plate
In card slot, fastening item is pressed, spring steel plate is in bending state at this time, provides pressing force to shoulder belt axis, is tightly attached to shoulder belt axis
On headrest pulling plate in corresponding card slot；
2) quick-disassembling method: lifting spanner makes to fasten item no longer to the first shoulder belt axis regulating part and the second shoulder belt axis regulating part
Pressuring action, the first shoulder belt axis regulating part and the second shoulder belt axis regulating part open rapidly under the effect of spring steel plate elastic force at this time,
Entire shoulder belt is adjusted fixed and quick-disassembly structure to remove from headrest pulling plate；
(4) have the application method of the child safety seat ISOFIX interface unlocking structure of anti-error Trigger Function:
1) the standard ISOFIX short interface for being mounted on the two sides of pedestal fixed frame is snapped into the interface of automobile seat rear
In, i.e., child safety seat is fixed on automotive seat, unlocks toggle at this time under the elastic force effect of pressure spring to far from standard
The direction of ISOFIX short interface is mobile, and the slot bottom on ISOFIX interface unlocking structure is covered；
2) toggle will be unlocked to stir to the direction close to standard ISOFIX short interface, unlock toggle no longer covers slot bottom
Portion, unlock knob expose, and operator protrudes into finger and pulls unlock knob, and standard ISOFIX short interface and automobile seat rear connect
Mouth separation；
(5) drawstring fixing means on:
1) the upper drawstring fixed link being fixed on upper drawstring one end in chair body fixing seat；
2) upper drawstring can be made from top to bottom by what the upper side top that the upper drawstring other end is upward through back cushion structure was arranged
The channel design passed through, the fixed anchor point being fixed on above automotive seat.
The utility model compared with prior art, has the following advantages that and effect:
(1) pedestal fixed frame and the detachable separate design in steel skeleton construction part: allow child safety seat positive and negative
To installation, the chair body fixing seat of steel skeleton construction part is placed on pedestal fixed frame, it can be achieved that automatic locking, make pedestal with
The chair back securely connects, and the safety is improved for children riding；
(2) design of the bent beam of steel skeleton construction part: suitable for blow molding or injection molding process will be utilized to produce
The child safety seats components such as headrest, chair body are installed on it, and bent beam convenient for children safety seat adjusts angle, improve children and multiply
Comfort is sat, and its impact resistance is good, good rigidity；
(3) chair body part rear design has back cushion structure: can make the chair body part discord automotive seat of child safety seat
It is directly in contact, facilitates children's seat and angle is adjusted；
(4) it devises the child safety seat ISOFIX interface unlocking structure for having anti-error Trigger Function: being solved by design
Toggle is locked, if needing that unlock toggle is first toggled it to side, unlock toggle no longer covers the bottom of slot before pulling unlock knob
Portion, at this time unlock knob expose, can be operated unlock knob be unlocked, thus largely prevent children or its
He is detached from child safety seat and automotive seat by personnel misoperation unlock knob, has ensured the safety of children；
(5) by the fixation point design of upper drawstring one end in chair body fixing seat: when child safety seat carries out chair back angle modulation,
Without upper drawstring of loosening；Upper drawstring is fixed on the chair back in compared with the prior art, and upper drawstring is fixed in chair body fixing seat
Have the advantages that more solid and reliable.
