Abstract
The utility model provides a children safety chair backrest angle adjusting device, which comprises a base, an adjusting mechanism and a backrest. The angle of the backrest relative to the base can be adjusted through the adjusting mechanism. The children safety chair backrest angle adjusting device is characterized in that the base is hollow so as to be provided with an inner cavity. The two sides of the inner cavity are respectively provided with a plurality of positioning grooves and a guide groove. The positioning grooves are matched with the adjusting mechanism so as to realize the positioning effect. The adjusting mechanism can slide through the guide groove. The guide groove is arc-shaped and is arranged at the lower part of the positioning grooves. The plurality of positioning grooves are arranged along a circular arc line from front to back. The circular arc line is formed by a plurality of arc segments connected together end to end and the arc segments are different in radius. The radiuses of the plurality of arc segments are gradually increased from front to back. Compared with the prior art, due to the special arrangement of the positioning grooves arranged along a special circular arc line, the range of inclination angle of the backrest relative to the base is greatly extended, so that the children safety chair is more comfortable and safer to use for children.
Description
Technical field
The utility model relates to a kind of child safety chair, relates in particular to child safety chair chair back angle regulator.
Background technology
Child's safety seat for vehicle is to aim at child safety to ride and a kind of restraint device of design-calculated.When take children hour, especially for the baby, need let children's ride-on in the child safety seat that relatively lies low, so promptly improved the safety that children ride, it is more comfortable to let children ride again; And when children grow up, need a bevelled or more upright position again.This just requires this type of child safety seat to possess bigger chair back angle of inclination control system.In existing child safety seat, in order to regulate the angle of inclination of the chair back, mainly contain following mode: one is single rail structure; Slide rail is installed in the middle of the chair back and the base, and the last slide rail and the chair back fix, and glidepath and base are fixed; Slide in glidepath through last slide rail; Produced the angle variation, thereby reached the purpose of chair back angular adjustment, but this structure chair back rocks big with respect to base and chair back tilt adjustable scope is too small.Other structure has the double sided slider bar structure, and this structure can effectively avoid the chair back with respect to the rocking of base, but needs two hands operate the adjusting that could realize chair back angle simultaneously, unusual inconvenience during use, and also angle of regulation range is too small.In sum, the chair back angle regulator of existing child's safety seat for vehicle, its structure is still waiting to improve.
The utility model content
The utility model technical matters to be solved is to provide a kind of chair back angle of regulation range big child safety chair chair back angle regulator to the above-mentioned state of the art.
The utility model another technical matters to be solved provides a kind of chair back combines the back firm, stable, is difficult for rocking with base child safety chair chair back angle regulator.
The utility model another technical matters to be solved provides the child safety chair chair back angle regulator of a kind of chair back and base angular adjustment one-hand operation.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: a kind of child safety chair chair back angle regulator; Comprise base, regulating mechanism and pass through this regulating mechanism chair back of base angular adjustment relatively; It is characterized in that described base hollow forms built-in chamber; These both sides, built-in chamber form the shift slot and the guide groove that supplies regulating mechanism to slide that a plurality of and aforementioned regulating mechanism cooperates the location respectively; This guide groove is circular arc and is positioned at the shift slot below, and described a plurality of shift slots arrange along a circular arc line that from front to back this circular arc line is formed by connecting before and after the multistage radius different arcs; And the multi-section circular arc radius increases from front to back gradually.
As preferably, described regulating mechanism can comprise
Front frame; Can be arranged in the aforementioned built-in chamber movably forward and backward and be connected fixing with the chair back of said base; Both sides have two orienting lugs, and each orienting lug laterally forms first through hole and horizontal first guide part that cooperates guiding with said guide groove to outer lug;
Handle is arranged between the orienting lug of aforementioned front frame and can moves forward and backward, and the rear end has two second through holes that are " eight " font;
Gear block is two, and each gear block is inserted in first through hole separately and has first protuberance that stretches out aforementioned first through hole and then can cooperate the location with shift slot and reaches second protuberance that upwards stretches out second through hole; And
Bringing-back mechanism forces aforesaid two gear blocks to keep mutual open trend all the time.
The preferred following design of Bringing-back mechanism: described front frame has a connection piece between two orienting lugs; Described Bringing-back mechanism comprises a retracing spring and is located at the strut rail in the handle; The front end of this retracing spring is connected with aforementioned strut rail, and the rear end then offsets with the front end face of attaching parts or is connected.
For making the smooth and easy convenience of angular adjustment, it is planar that the bottom surface of the said chair back is protruding cylinder, and accordingly, it is planar with the cylinder of the suitable indent in aforementioned chair back bottom surface that the upper surface of said base is.
Described after poppet both sides all have second guide part that can move around in said guide groove rear end of lateral projection.
Further, the suitable inner concave arc surface that is in the upper surface of described orienting lug and chair back bottom surface, and described attaching parts takes the shape of the letter U and is connected between the orienting lug, described first guide part takes shape in the orienting lug lateral surface.
For making relative base slip of the chair back and positioning combination more steadily reliable, said chair back rear end is fixedly connected with an after poppet, and this after poppet is positioned at the rear end of aforementioned front frame and can be arranged at the built-in chamber of said base movably forward and backward.
Compared with prior art, the advantage of the utility model is: because shift slot adopts distinctive camber line shape to arrange, make the chair back regulate the angle of inclination with respect to base and expand greatly, and then make the baby take more comfortable, the safety of safety seat.The chair back combines with base reliably, is difficult for rocking, and the angle of inclination of the one-hand operation adjusting child safety seat chair back, easy and simple to handle; Integral structure is simple, is convenient to produce, assemble.
