[specific embodiment]
About aforementioned and other technology contents, characteristics and effect of the present invention, in the middle of following cooperation describes in detail with reference to graphic embodiment, can clearly present.
See also Fig. 1 and Fig. 5, it illustrates the exploded view of looking according to outside drawing, exploded view, the back side of the chair back bustle automatic regulating apparatus of an embodiment of the present invention, outside drawing and the cutaway view that the back side is looked respectively.As shown in the figure, the chair back bustle automatic regulating apparatus according to an embodiment of the present invention comprises a chair back 100, an adjustment unit 200 and a bustle 300.
The chair back 100 is installed on the seat support 400 (seeing also Fig. 6 and Fig. 7).The chair back 100 has relative positive 110 and one back side 120; By overlooking, the chair back 100 has the radian that matches and answer with human body back, when human body is taken in seat support, supplies the usefulness as the dependence of human body back.
The bottom surface 233 of slide block 230 convexes with to match with spring 240 answers three guide pillars 234 of quantity, the bottom surface 224 of lid 220 then to be provided with three guide grooves 225 that position and quantity with guide pillar 234 match and answers.Each spring 240 overlaps respectively and is overlying on each guide pillar 234 and is placed in each guide groove 225 respectively.Make according to this each spring 240 by standard stably in set space and the path flexible, provide the stable elastic acting force of slide block 230 1.
The inner face of department of assembly 210 be provided with several for example three directly to raised line 211,235 at a back side of slide block 230 abuts in these directly to raised line 211.In the middle of the process that slide block 230 slides up and down, directly can reduce the friction area of slide block 230 back sides 235 and department of assembly's 210 whole inner faces to raised line 211, and then promote the smoothness that slide block 230 slides.
Directly the wherein raised line to raised line 211 is provided with the edge directly to spaced several locating slots 212, the back side 235 of slide block 230 then is equiped with an elasticity positioning bead body 236 that matches and answer with locating slot 212, the attitude of taking along with the user when slide block 230 is adjusted the position up and down and is arrived one both during allocation, the elasticity positioning bead body 236 of slide block 230 snaps into a wherein locating slot of several locating slots 212, and keep slide block 230 in this position of adjusting this moment, make its tool stability.
Bustle 300 has relative positive 310 and one back side 320; By overlooking, bustle 300 has the radian that matches and answer with the human body waist, when human body is taken in seat support, supplies the usefulness as the dependence of human body waist.The back side 320 of bustle 300 is hubbed at adjustment unit 200 with a pivot 250, thereby for adjustment unit 200, bustle 300 is to be the rotation that axle is layback or leans forward with pivot 250.
With regard to the pin-jointed structure between bustle 300 and the sliding adjustment unit 200, on implementing, the back side 320 of bustle 300 convexes with one second pin joint seat 330, this second pin joint seat has at the boss 331 of its both sides and the recess 332 between this two boss, 232 of first pin joint seats of slide block 230 are placed in the recess 332 of second pin joint seat 330, and articulate two boss 331 of first pin joint seat 232 and second pin joint seat 330 with pivot 250.Thereby bustle 300 can slide up and down along with slide block 230 one, and can be further on the residing position of slide block 230, be axle and rotate front and back with pivot 250.
See also Fig. 6 and Fig. 7, it illustrates respectively according to the chair back bustle automatic regulating apparatus of an embodiment of the present invention use schematic diagram when human body is in difference and takes attitude.As shown in Figure 6, when human body 500 was taken in seat support 400 and is in for example rest attitude, the waist of human body 500 was the attitudes that are layback and sink; This moment, the backward wing of human body 500 waists, can drive bustle 300 is axle rotate backward (rotating to up time bell direction) with pivot 250; Simultaneously, the sinking of human body 500 waists action can drive slide block 230 via bustle 300 and glide, and makes bustle 300 move down thereupon; Layback and the bustle 300 that glides in the time of according to this and the waist that supports human body layback 500 this moment effectively and sink.
Relatively, as shown in Figure 7, when human body 500 was taken in seat support 400 and for example is in operating attitude, the waist of human body 500 was to be the straight and upright attitude that turns forward slightly and make progress; This moment, the forward swing of human body 500 waists, can drive bustle 300 is axle and rotate (rotating to inverse time bell direction) forward with pivot 250; Simultaneously, the straight and upright action that makes progress of human body 500 waists, because the active force that acts on slide block 230 reduces, slide block 230 be can according to its spring 240 and go up sliding, make bustle 300 with on move; Lean forward in the time of according to this and go up sliding bustle 300 and support the human body straight and upright waist that leans forward and make progress 500 this moments effectively.Therefore, no matter human body 500 is in the rest attitude or is in the different attitudes of taking of operating attitude etc., the bustle 300 of the chair back 100 all can be adjusted the position thereupon, makes the waist of human body 500 obtain bustle 300 effective support and dependence.
Chair back bustle automatic regulating apparatus according to an embodiment of the present invention, the position of its bustle 300 can be adjusted automatically along with the position of human body waist, make the waist of human body can both obtain effective support and dependence at any time, lower the burden of human body waist, and make its ride comfort.The above reaches creation purpose of the present invention really.
Though the present invention discloses as above with embodiment; right its is not in order to limiting the present invention, anyly has the knack of this skill person, without departing from the spirit and scope of the present invention; when can being used for a variety of modifications and variations, so protection scope of the present invention is as the criterion when looking the claim person of defining.
