Description
Technical field
The utility model belongs to the seats for children in vehicles field, a kind of specifically chair back inclined angle regulating mechanism that is used for child seat chair back angular adjustment.
Background technology
Along with expanding economy; improving constantly of people's living standard; automobile; especially the family expenses small passenger car has more and more become the daily walking-replacing tool of people; in general; the adult uses of seat belts and can guarantee its safety substantially; and the safety of children's ride-on small passenger car is not resolved; for this reason; developed the child seat that aims at designed for children; child seat is fixed on the automotive seat,, can forms better protection children because child seat more agrees with children's body type; but child seat fixedly is the key factor that influences its safety performance; putting before this, people have proposed the notion of International Standardization Organization's anchor fitting (isofix), and this anchor fitting is to aim at the fixing of child safety seat and a cover system of exploitation.Its maximum characteristics make the installation of child safety seat become easy to be more firm with regard to being, the more important thing is that it makes again the normalisation that is connected between seat and the child safety seat of different brands is of value to the popularization of child safety seat.There are some researches prove that the standardized child safety seat mounting means of isofix can reduce by 22% with 0-4 year children's injures and deaths situation.The isofix system no longer needs to use car belt to fix, but child safety seat and body structure is integrated at all, has also solved the problem that child safety seat chair apparatus difficulty, mistake are used.
But the isofix device uses and also to bring a series of problems, and wherein one is exactly that the chair back angle of child seat can not be regulated the traveling comfort when having influenced children's ride-on greatly.
Summary of the invention
The utility model provides a kind of chair back inclined angle regulating mechanism that can conveniently regulate child seat chair back angle at deficiency of the prior art.
In order to solve the problems of the technologies described above, the utility model is solved by following technical proposals: chair back inclined angle regulating mechanism, comprise the base and the chair back, the described chair back is arranged on the described base, described base is provided with slide plate, the lock slots that slide plate is provided with chute and communicates with described chute, also comprise seesaw, described seesaw is provided with S. A. and oscillating axle, described S. A. is arranged on and leans on midway location on the described seesaw, and described oscillating axle is arranged on described seesaw one end, and described S. A. is articulated on the described chair back, also comprise reset attachment, described oscillating axle at roof pressure under the effect of described reset attachment in described lock slots.
Under general state, oscillating axle is stuck in the lock slots under the effect of reset attachment, and this moment, the angle of the chair back can't be regulated.When the needs adjusting angle, pull an end relative with oscillating axle on the seesaw with hand, seesaw is that rotate at the center with the S. A., and the oscillating axle of the seesaw other end is along with seesaw rotates lock slots, enter in the middle of the chute, oscillating axle and S. A. can slide in chute, and the seesaw and the chair back also can be followed together and slide, and chair back angle changes thereupon during slip, when arriving suitable angle, unclamp seesaw, oscillating axle snaps in the lock slots under the effect of reset attachment once more.Control process is quick and convenient, and regulating mechanism is simple, novel.Reset attachment has multiple, does not enumerate one by one here, oscillating axle can be returned to the device in the lock slots after the intact chair back angle of every each adjustment, all belongs to protection domain of the present utility model.
Skid off chute when preventing that oscillating axle and S. A. from sliding in chute, and then make the chair back and base be separated, be provided with in the described chute and stop that oscillating axle skids off the block face first of chute, be provided with in the described chute and stop that S. A. skids off the block face second of chute.
Specific embodiment, the described chair back comprises main part and connecting panel, described connecting panel is arranged on described main part bottom and extends downwards.Described connecting panel is provided with fulcrum hole and swing spacing hole, and described S. A. is articulated on the described chair back by described fulcrum hole, and described oscillating axle passes swing spacing hole.
Concrete, wherein a kind of structure of reset attachment is, described reset attachment comprises spring, and described spring one end is arranged on the described seesaw with respect to the other end of described oscillating axle, and the other end of described spring withstands on the described chair back.In the time of need not regulating chair back angle, spring handle seesaw one end is toward pressing down, and the other end of seesaw promptly is equipped with an end of oscillating axle then toward upwarping, and oscillating axle holds out against lock slots under this trend that upwarps, can not skid off.This reset attachment is simple in structure, and is reliable, is the preferred reset attachment of the utility model.
The utility model also comprises block, described block is arranged on the both sides of the described chair back, and described block props up described base side, and described block is provided with cylinder, described base both sides are provided with the slide rail face, and the outside face of described cylinder and described slide rail face contact.Block props up two sides of base, prevent chair back double swerve on base, the outside face of cylinder and slide rail face contact, and cylinder is realized being connected of the chair back and base, prevent that the chair back and base from throwing off, and can slide along slide rail face pulsation-free when making chair back angular adjustment.
Scheme more specifically, the two ends of described slide rail face are provided with the block face third that stops cylinder.Block face third can effectively limit the scope of chair back angular adjustment, cooperates block face first and block face second, can prevent effectively that the chair back and base are separated.
The beneficial effects of the utility model are: as long as pull seesaw, oscillating axle withdraws from lock slots, the chair back angle of child seat can be regulated fast, easily, openhanded opening after the seesaw, oscillating axle can rely on reset attachment to enter lock slots again, realize the location, the location after the angular adjustment of the chair back and angular adjustment are intact is all very convenient, quick.
