Abstract

The utility model relates to a buffer layer structure for vehicle children safety seats, belonging to the daily necessary technical field, wherein the rigid seat frame of the common vehicle children safety seat is sheathed by a buffer layer for damping vibration and absorbing energy, as buffer cushions of some thickness, such as sponge or cotton at seat, back and headrest, the buffer cushion are independently arranged without connection, having complex installment and easy displacement in use, to cause bad protection children under collision and bad convenience. The utility model provides a buffer layer structure of simple installment, no displacement in use and good shock absorption and buffer effect, for vehicle children safety seats, which comprises a plurality of buffer cushions sheathed at different parts of a seat, wherein the buffer cushions are interlocked. The buffer cushions of interlocking structure realizes better collision resistance and shock absorption effect, is hard to displace in use after being sheathed on a seat to confirm normal application, and has simple installment.

Description

The buffer layer structure of child's safety seat for vehicle

[affiliated technical field]

The utility model relates to daily necessities field, particularly a kind of buffer layer structure of child's safety seat for vehicle.

[background technology]

The hard chair frame of common safety chair seats of car for children is equipped with the cushion layer that the damping energy-absorbing is used outward more, these cushion layers mostly are some and are placed in each one of chair frame certain thickness cushion rubber is arranged, as the seat, lean against, the sponge of head rest position or cotton-wool etc., wrapping the cloth cover at last becomes client sees sale in market finished product child's safety seat for vehicle.Each cushion rubber is separate to be laid, onrelevant, and trouble not only is installed, and the easy loose shift of each locational cushion rubber in use, particularly when external impacts to a little less than the children's torso protection effect, comfort level is poor; Especially do not have cushion rubber on the handrail of seat both sides, fill out the cloth cover of a small amount of bullet wadding in only coating, the bullet wadding is in use also easily because of regular touching skewness, and the armrest of rigidity very easily waves to get to for active active child, has potential safety hazard.

[utility model content]

The technical assignment of the technical problems to be solved in the utility model and proposition is, provides a kind of easy for installation, in use is difficult for loose shift, the buffer layer structure of the child's safety seat for vehicle that damping, buffering is respond well.

The utility model adopts following technical scheme: the buffer layer structure of child's safety seat for vehicle, comprise some cushion rubbers that are nested with at chair frame different parts, and it is characterized in that described some cushion rubbers are conjoined structure.Originally the independent cushion rubber that is provided with is made into the cushion rubber of conjoined structure, and the shock resistance damping performance is better, has strengthened the safety performance of child safety seat greatly; The cushion rubber of conjoined structure in use is difficult for loose shift, effectively guarantees its normal operation, installs also very convenient.

The cushion rubber of conjoined structure described in the utility model comprise lean against cushion rubber and on prolong the disjunctor head rest cushion rubber that expansion forms.According to using needs that disjunctor head rest cushion rubber is set and leaning against the protection that neck and the vertebra of cushion rubber to children's most fragile partly provides safe enough.

The cushion rubber of conjoined structure described in the utility model comprises the seat cushion cushion rubber and is symmetrically distributed in the handrail cushion rubber of its both sides.The handrail cushion rubber that extends to form by seat cushion cushion rubber both sides has been eliminated existing armrest not to be had the individual buffer layer and only relies on the too thin defective of bullet wadding, and handrail cushion rubber touch perception concerning the active children of seat safe in utilization uses safer well; Conjoined structure is convenient to the assembling of later stage cushion rubber and chair frame, and this outer armrest cushion rubber is close to the handrail installation surely according to the handrail profile, installs the whole cushion rubber in back and is difficult for loose shift, fully guarantees the result of use of cushion rubber.

The cushion rubber of seat cushion described in the utility model is provided with the safety lock mounting hole, is convenient to the assembling of later stage and special-purpose child belt.

The cushion layer of conjoined structure described in the utility model comprises the head rest cushion rubber, leans against cushion rubber, seat cushion cushion rubber and handrail cushion rubber, and described head rest cushion rubber prolongs expansion and forms for leaning against on the cushion rubber, and the handrail cushion rubber is symmetrically distributed in seat cushion cushion rubber both sides.The head rest cushion rubber, lean against cushion rubber, seat cushion cushion rubber and handrail cushion rubber and be made of one structure, easy for installation, the protection effect of bumper and absorbing shock is better.

The thickness of cushion rubber described in the utility model is 0～2cm.This thickness can guarantee that cushion rubber can also provide good damping, buffering effect when keeping light and handy convenient bending to be nested with the chair frame.In addition, can be according to the human engineering principle to the cushion rubber of different parts design different-thickness, the seat cushion that is pressed onto as health and lean against the position can be thicker than the handrail position.

Cushion rubber described in the utility model is that cold sponge of polyurethane made, and is identical with common seat cushions sponges cover manufacturing process, the convenient realization.

The utility model substitutes the cushion rubber that independently is nested with on the existing child safety seat by the cushion rubber of cold foaming conjoined structure, whole parcel chair frame, good damping, buffering effect is provided, strengthens the seat safety in utilization, eliminate the potential safety hazard of rigidity chair frame the potential injury of active children; The cushion rubber of conjoined structure and chair frame convenience quick for installation; The cushion rubber of conjoined structure in use is difficult for displacement, good operating stability, and children use touch perception better.

Among the figure: 1. the chair frame, 2. the handrail cushion rubber, 3. the seat cushion cushion rubber, 4. the safety lock mounting hole, 5. the head rest cushion rubber, 6. lean against cushion rubber.

[specific embodiment]

Below in conjunction with the description of drawings and the specific embodiment the utility model is described further.

Embodiment 1 as depicted in figs. 1 and 2, the buffer layer structure of child's safety seat for vehicle comprises a seat cushion cushion rubber 3 that is used to be placed on the seat, seat cushion cushion rubber middle part has the safety lock mounting hole 4 that connects special-purpose safety strap; The handrail cushion rubber 2 that being provided with symmetrical distribution and can being close to the handrail surface is extended in seat cushion cushion rubber both sides, cold sponge of the polyurethane that handrail cushion rubber and seat cushion cushion rubber are formed in one, and cushion rubber thickness is 1.5cm.

During installation siamesed handrail cushion rubber and seat cushion cushion rubber be nested with the corresponding position at chair frame 1, the handrail cushion rubber is close to the armrest portion on the parcel chair frame, gets final product by existing production technology outsourcing cloth cover then.The cushion rubber of this conjoined structure is easy for installation, the production efficiency height; The back cushion rubber is installed is difficult for loose shift, the cushion rubber of conjoined structure helps evenly to disperse external impacts when meeting accident, and strengthens the protection effect of seat, has improved the safety that seat uses.
