Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, this case is described in further detail.
This case relates to a kind of attitude-adjusting system of child safety seat, and seat as shown in Figure 1, has cushion frame 1, headrest 2 and base 4.Headrest 2 is located on cushion frame 1, and base 4 is located at bottom cushion frame 1.Cushion frame 1 specifically can by seat skeleton, belt stopper clamp mechanism, plate is wrapped up in bottom, plate is wrapped up at back, safety strap binding clasp etc. is formed.This base 4 is made up of the upper cover 41 mutually fastened up and down and lower cover 42.
The forward side of described base 4 is provided with this novel gesture adjusting mechanism.As Figure 2-3, this attitude-adjusting system 5 comprises tension arm 51, gear groove and return spring 53.
Tension arm 51, in reverse V-shaped shape structure, is rotationally connected with cushion frame 1 in the middle part of it.Specifically, the middle part of tension arm 51 is provided with the first circular hole 510, and cushion frame 1 is provided with the second circular hole 13(see Fig. 4), rotate together with round bar 511 is rotationally connected with by one between this first circular hole 510 with the second circular hole 13.One end of tension arm 51 is arm end 512, and the other end is provided with link stopper portion.This link stopper portion specific design mode is, the other end in tension arm 51 is provided with a gear round bar 513, and the both ends of this gear round bar 513 are configured to link stopper portion 5131 toward extension.Described gear groove be used for link stopper portion 5131 with the use of, it can be directly located on base 4, provides in embodiment, and gear groove is formed on a card article 52, this card article 52 is provided with abreast several gears 521, for link stopper portion 5131 embed realize position-limiting action.Base 1 is provided with card article installation position 411, installs for card article 52 adaptation.
Described return spring 53 elasticity is to being located at tension arm 51 with on cushion frame 1; Specifically, tension arm 51 is provided with arm boss 514, and cushion frame 1 is provided with blind hole boss, return spring 53 is provided with two, they are all set in rotates on round bar 511, and two torque arm are respectively to being located on arm boss 514 and blind hole boss, carries out spacing and reach the object of self-return with this.
Described base 4 rearward side is provided with an adjust bar 54, and cushion frame 1 is provided with regulating tank 14, and this regulating tank 54 is specifically in strip structure.Adjust bar 54 penetrates regulating tank 14, and can move around in regulating tank 54.
Preferably, in order to strengthen the mating reaction between cushion frame 1 and base 4, and be beneficial to the pose adjustment effect of cushion frame 1 respect thereto 4, the rear side of cushion frame 1 is provided with two camber reinforced ribs 15, base 4 is provided with limit guide rail 412, two camber reinforced ribs 15 sink in limit guide rail 412 respectively adaptedly, adopt camber outline to coordinate between the two.Regulating tank 14 is located on camber reinforced rib 15 particularly.
When cushion frame 1 carries out pose adjustment, finger force is along ground to pull-up tension arm 51, whole mechanism is that centre of gration is toward left-hand revolution to rotate round bar 511, therefore make gear round bar 513 depart from the gear 521 of card article 52, now cushion frame 1 part is in active state, cushion frame 1 part can rotate by predetermined attitude regulation track, and then reach the object of attitude regulation, this attitude regulation track determined by regulating tank 14, finally unclamp tension arm 51, mechanism's self-return is made by return spring 53, gear round bar 513 is coordinated with a corresponding gear 521, and then reach the object of attitude regulation.
