Description

Vehicle-mounted juvenile motor vehicle safety restraint system head rest control apparatus

Technical field

The present invention relates to a kind of vehicle-mounted juvenile motor vehicle safety restraint system, is a kind of control apparatus that is used to regulate vehicle-mounted juvenile motor vehicle safety restraint system head rest upper-lower position specifically.

Background technology

The vehicle-mounted constrained system of children is a kind of children safety system with the car colleague, is mainly the child safety seat seat assembly, can effectively protect children's traffic safety.Normal children's safety seat is made up of base, backrest and head rest, and base is used to connect automobile ISOFIX captive joint, and backrest and head rest are respectively applied for children back and head are supported.The traditional children safety seat is formed in one or the fixation group assembling structure; Can't regulate, because the growth of child development phase is very fast, the child safety seat that must often change bigger specification, model could satisfy operating needs; Increased customer using cost virtually, poor for applicability.

The child seat of existing changeable cushion; Like the patent No. is 201020516166.6 disclosed a kind of automobile children safety chairs, and head rest passes the head rest adapter plate through the gear shift plate and is connected on the backrest, utilizes the guide groove that is provided with on the head rest adapter plate and positioning groove to realize the head rest stationkeeping of differing heights; Children to satisfy different times use; But its operation is loaded down with trivial details, and the fixing and adjusting of each gear all need be dismantled the downward modulation plate washer, is repositioned onto in corresponding guide groove and the positioning groove fixing again; Waste user's time, use very inconvenience; Like the patent No. is the disclosed a kind of child safety seat for automobiles head rest arrangement for adjusting height of 201020530032.X, and the applicant is the vehicle-mounted constrained systems of the adjustable children of 201120392840.9 disclosed omnibearing stereos in the patent No. of first to file, all adopts two slide openings of regulating control herringbone to move along the backrest height direction in slide opening through latch one end; Latch other end parallel motion is plugged together or break away from the backrest slot, thereby realize that head rest along going up and down to be fixed on the backrest height direction, plays the effect of adjusting head rest; Regulate simple operation; Can effectively solve the problem that children growth causes adapting to use fast, take into account easy to usely, but its drive disk assembly is more; Complex structure; Manufacturing cost is high, and latch one end that places slide opening receives two vertically and the power of level two directions at slide opening, and long-term stressed wearing and tearing are fracture damage very easily; Cause and can't regulate by head rest, service life is shorter relatively.

Summary of the invention

In order to solve in the prior art head rest control apparatus complex structure on the child safety seat, manufacturing cost is high, operation inconvenience; Service life is short, and the fragile deficiency that waits the invention provides a kind of simple in structure; Easy and simple to handle; Adjustment structure is stable, long service life, the vehicle-mounted juvenile motor vehicle safety restraint system head rest control apparatus that make, use cost is low.

The technical scheme that the present invention adopts is: a kind of vehicle-mounted juvenile motor vehicle safety restraint system head rest control apparatus, comprise the head rest and the regulating mechanism that are installed on the seat body, and its technical characterstic is that said regulating mechanism comprises regulating plate, stick, slide rail and slide rail tooth; Regulating plate is installed on body back; The regulating plate dual-side is tooth bar, and stick is flush-mounted in and is the state of sliding up and down in the head rest, and the lower end of stick connects slide rail; Head rest connects slide rail; Slide rail is horizontally placed between two tooth bars, is provided with left and right slide rail tooth in the said slide rail, connects spring on the left and right slide rail tooth and is protruding or inside indentation simultaneously; Slide rail is provided with the spacing mouth of leading of a corresponding left and right slide rail backlash, and the lower end of stick is movably set in spacing leading and is the state that inserts or break away from left and right slide rail inter-lobe clearance in the mouth.

Be equipped with shoulder belt on said head rest or the regulating plate.

Adopt above technical scheme, of the present invention have a following beneficial effect: when head rest was regulated, the pulling stick upwards slided in head rest; The lower end of stick breaks away from left and right slide rail inter-lobe clearance in spacing lead mouthful, draw on the head rest to make left and right slide rail tooth overcome acting force of the spring to move up inwardly being retracted within on the regulating plate tooth bar on the slide rail, when head rest transfers to institute palpus position; Unclamp stick, insert in the left and right slide rail inter-lobe clearance spacing leading in the mouth lower end of stick, and left and right slide rail tooth is clamped between the regulating plate tooth bar by the stick lower end; The slide rail self-locking does not have mobile; The head rest fixing-stable, its adjusting is simple to operate, and drive disk assembly is few; Not fragile, long service life; When head rest or regulating plate slide up and down simultaneously, drive the shoulder belt that wears synchronously and move up and down the actv. safety strap protection of satisfying.

The present invention is by the telescopic moving or hold out against locking on the regulating plate tooth bar of left and right slide rail tooth in the stick of the head rest control slide rail, thereby realizes that being in harmonious proportion of head rest is fixing, and it is simple in structure, easy to adjust, stable, long service life.
