Abstract

The utility model is related to a kind of child seat head rest multi gear position adjustable bridge structures, including seat body, the chair back of seat body is equipped with the sliding slot extended up and down, guiding movement is equipped with headrest up and down in sliding slot, headrest is hinged with can be around the swing arm of the opposite overturning of the axis that left and right directions extends, the free end of swing arm is connected with the gear lever of left and right extension, the left and right ends of gear lever, which are respectively overlapped with, to be extended up and down and is fixed on the tooth row in seat body, and is connected between swing arm and headrest for gear lever to be pressed on the return spring in the tooth socket of tooth row.The mode overlapped in a tooth socket of tooth row using operating lever, headrest is locked to corresponding position, it is this relatively simple for structure, as long as and operate when to swing arm apply a return spring opposite force, it is adjusted with regard to that can unlock, also allowing for headrest adjusting, operation is very easy.

Description

Child seat head rest multi gear position adjustable bridge structure

Technical field

The utility model is related to a kind of children's seats, are specifically to be related to child seat head rest multi gear position height adjustment knot Structure.

Background technology

With reinforcement of the parent to child sitting cart awareness of safety, use of the child safety seat on automobile becomes increasingly It is universal.Children are growing tall daily, with the growth of height, the child safety seat used originally can not meet safety and Comfortable requirement, and common its height of headrest of child safety seat is usually what can not be adjusted at present, this means that With the growth of child's height, it is necessary to which the seat more renewed causes to waste to meet the requirement of safe handling.A small number of adjustable section headers The child safety seat of pillow height degree, adjustment structure is all more complicated, and adjusts knob and be typically disposed in chair back rear end, and when adjusting needs First the child safety seat on car seat to be disassembled, after completing the adjusting to height of headrest, then by children Safety seat is installed on car seat, operation and its inconvenience.

Invention content

The utility model is intended to provide child seat head rest multi gear position height a kind of simple in structure and easy to operate and adjusts Structure.

In order to solve the above technical problems, in the utility model child seat head rest multi gear position adjustable bridge structure technical side Case is as follows：

Child seat head rest multi gear position adjustable bridge structure, including seat body, the chair back of seat body is equipped with extension up and down Sliding slot, guiding movement is equipped with headrest up and down in sliding slot, and headrest is hinged with can be around the axis that left and right directions extend with respect to overturning Swing arm, the free end of swing arm is connected with the gear lever of left and right extension, and the left and right ends of gear lever are respectively overlapped with to be extended up and down And the tooth row in seat body is fixed on, and the tooth socket for gear lever to be pressed on to tooth row is connected between swing arm and headrest In return spring.

Swing arm is located at the back side of the chair back and overhangs to the back side of the chair back, and the high direction of tooth of tooth row is towards the back side of the chair back.

The hinged end of swing arm is equipped with and penetrates to the positive control terminal of the chair back, and control terminal, articulated section and free end are long along swing arm Degree direction is set gradually.

Lifting is connected with the operation handle that upper and lower guiding movement is assemblied on headrest in control terminal.

The beneficial effects of the utility model are：

Headrest is locked to corresponding position, this structure ratio by the mode overlapped in a tooth socket of tooth row using operating lever It is relatively simple, as long as soon as and while operating apply the opposite force of return spring to swing arm, can unlock and be adjusted, also allow for Operation is very easy for headrest adjusting.
