Description

Child safety seat headrest mounting structure

Technical field

The utility model belongs to vehicle-mounted child safety seat technical field, relates generally to a kind of child safety seat headrest peace Assembling structure.

Background technology

The skeleton of child safety seat is the central factor of safety seat safety, is equivalent to the frame in house, house Jail is insecure, sees that frame is known that.Currently, the bone of the relatively simple integrated children safety seat of common structure in the market Frame is made of blow molding process production.Blow molding process is that the molten plastic blank of extrusion is placed in mold, is then borrowed Help compressed air that melting charge inflation is affixed on cavity wall, after cooling hardened forming, therefore skeleton made of blowing is all Hollow.It is this through chair framework made of blow molding process since centre is hollow, thus its structural strength is relatively low so that The impact force born is relatively low, and the security performance using the children's seat of this skeleton production is also relatively low naturally；And it is existing Headrest is mostly fitted without on some children's safety skeletons, this seat has prodigious owe to the head of children and the protection of neck It lacks, be easy to cause the damage of children's incidence, and structure is fixedly mounted even if substantially being used if being equipped with headrest, thus nothing Method is adjusted according to the body development condition of children, and there are still security risks.

Utility model content

The purpose of this utility model is：A kind of child safety seat headrest simple in structure, intensity is high, safe to use is provided Mounting structure.

The technical solution of the utility model is：A kind of child safety seat headrest mounting structure, including chair framework, it is described Chair framework includes the seat and backboard of integrated injection molding, has in the left and right sides integrated injection molding of seat and is bent upwards Balustrade panel has the forward side guard plate of bending, at the rear portion or so of seat and backboard in the left and right sides integrated injection molding of backboard Interval is equipped with integrated injection molding integrally formed with two reinforcing ribs, and at the edge of the seat, backboard, balustrade panel and side guard plate It turns edge outside molding；It is further fixed on headrest mounting plate on the top of the backboard, is passed through on the front face of the headrest mounting plate A pair of of guide post guiding being symmetrical set is slidably fitted with headrest substrate, and height is equipped between headrest mounting plate and headrest substrate Low adjustment mechanism.

If the reinforcing rib includes a pair of of gusset of relative spacing setting and is spaced between being fixed on a pair of gusset Dry floor, a pair of of gusset are respectively perpendicular to the seat and backboard, be mutually parallel between each floor and relative to The seat and inclined back plate setting.

The reinforcing rib extends to the forward position of seat by the top sides edge of backboard, and described two are corresponded on the seat Reinforcing rib is symmetrical offers twice slot hole, which extands rearward to the circle between the seat and backboard At arc transition structure, a pair of of gusset in every reinforcing rib is divided into the left and right side edge of corresponding slot hole, is located in corresponding slot hole Floor top sides edge is flushed with the seat.

The height adjusting includes the vertical sliding slot for being set to headrest mounting plate center, is divided into sliding slot or so relatively Limited bayonet on cell wall and the corresponding closing piece component for being installed on headrest substrate back, the closing piece component include and headrest substrate The vertical sliding block for being oriented to slidable fit and symmetrical two fixture blocks being divided at left and right sides of sliding block, two fixture block and headrest substrate Laterally steering is slidably matched and is slidably matched with sliding block synchronization steering by symmetrically arranged twice tip chute, in headrest substrate Top be equipped with the button being sequentially connected by connecting rod and sliding block.

Reinforcing rib, seat, backboard and balustrade panel and side of the chair framework using integrated injection molding in the utility model Backplate, overall structure is simple, has the characteristics that light-weight, intensity is high, impact resistance is big, can effectively improve child safety seat The safety and reliability of chair, the headrest substrate installed on chair framework can be developed according to children's torso carries out height adjustment, It not only plays a good protective effect to the incidence of children, while the service life of child safety seat can be extended.
