The specific embodiment
About aforementioned and other technology contents, feature and effect of the present utility model, following, coordinate in the middle of embodiment with reference to accompanying drawing describes in detail, can clearly present.
Refer to Fig. 1 to Fig. 5, according to the back support adjustment structure of the utility model one embodiment, comprise a seat support 100 and a flexibility chair back 200.
The rear end of seat support 100 has a backboard projecting upwards 110, this backboard be provided with along the above-below direction of seat support 100, extend always to chute 111.
The flexibility chair back 200 has two side frame portions 210 and the chair back body 220 between this two side frames portion.The bottom of two side frame portions 210 is connected in respectively two sides of the backboard 110 of seat support 100.Chair back body 220 has superposed one and leans against portion 221 and a waist support portion 222 that is positioned at bottom and gives prominence to forward, wherein, lean against portion 221 and respectively with a junction 223, continue mutually with two side frame portions 210, waist support portion 222 is separated and has a gap 224 with two side frame portions 210.The back side of waist support portion 222 is provided with and a straight projection 225 to chute 111 corresponding quantity, and it is placed in slidably directly to chute 111.Directly to chute 111, can limit the sliding stroke of projection 225 and the projecting degree of restriction waist support portion 222.
There is a packing ring 240 end of projection 225 with screw 230 lockings, and this packing ring is positioned at the back side of backboard 110, in order to prevent that projection 225 is from directly departing to chute 111.
The back side of backboard 110 is provided with a cover plate 120 with for example screw group, and it covers on the straight outside to straight trough 111, screw 230 and packing ring 240, in order to maintain the apparent integrality of backboard 110.
The portion that leans against 221 of chair back body 220 and waist support portion 222 offer a plurality of air-vents 226, make occupant's back have air permeable effect.
See also Fig. 6, when occupant 300 rides on seat support 100, and back 310 is leaned on when the flexibility chair back 200, the dependence weight of its human body back 310 can force the portion that leans against 221 and 210 hypsokinesis of two side frame portions of the flexibility chair back 200, and because there is gap 224 between the waist support portion 222 of the flexibility chair back 200 and two side frame portions 210, therefore waist support portion 222 can't be along with leaning against portion's 221 consubstantiality hypsokinesis, but the hypsokinesis action meeting that leans against portion 221 relative make waist support portion 222 take connecting portion 223 as axle prominent grand forward, and according to occupant's dependence degree of facing upward in various degree, waist support portion 222 can produce in various degree corresponding prominent grand forward.
Say in detail again it, occupant 300, ride on seat support 100, and human body back 310 is leaned on when the flexibility chair back 200, when occupant's 300 human body backs 310 are more swung back, occupant's waist 320 is relative healing forward, and the waist support portion 222 that now the dependence weight of human body back 310 can be impelled the flexibility chair back 200 more grand (simultaneously, the set projection 225 in waist support portion 222 back sides is along directly to chute 111 upward slidings), therefore, occupant 300 now waist 320 forward can be subject to corresponding degree forward prominent grand waist support portion 222 effectively support and rely on, lower the burden of human body waist, when occupant's 300 human body backs 310 turn forward, occupant's waist 320 is backward relative, and now human body back 310 can alleviate leaning against exerting pressure of portion 221, relatively making to protect splenium 222 reclaims backward and lowers waist support portion 222 prominent grand degree is (simultaneously forward, the set projection 225 in waist support portion 222 back sides is along directly to chute 111 down slidings), therefore, the occupant 300 waist support portion 222 that now waist 320 backward can be subject to corresponding prominent grand degree effectively supports and relies on, and lowers the burden of human body waist.
Back support adjustment structure according to the utility model one embodiment, can according to occupant different take attitude, the prominent grand degree in front and back of corresponding automatic adjusting back waist support portion at any time, make occupant's waist can obtain effective support and dependence at any time, lower the burden of human body waist, and make its ride comfort.
Although the utility model discloses as above with embodiment; so it is not in order to limit the utility model; anyly be familiar with this skill person; within not departing from spirit and scope of the present utility model; when being used for a variety of modifications and variations, the scope that therefore protection domain of the present utility model ought define depending on appending claims is as the criterion.
