It is automobile-used additional with back of the body angle back-supportedTechnical field
The invention belongs to additive products manufacturing technology on the seat of vehicle.It is mainly used in automobile, electric car, aircraft, railcar, ship, agricultural vehicle, tractor, engineering truck, on transport facility, naturally it is also possible to for furniture, be used as most casesUnder the back-supported put on the seat that can be used alone.
Background technology
The backrest of present automotive seat, is called hip rear portion below, successively upwards, lumbar support, back-supported, shoulder waterFlat rubber belting support, neck rear portion, head support.Present market, additional back-supported, is not only sold to the present invention not phaseThe lumbar support of pass（I.e. waist is rested the head on）, lumbar support is all soft-body either mesh, is belonged to waist pressure distortion, is not to becomeAngle.Its application, is all to support application simultaneously with the back-supported of backrest, shoulder horizontal stripes, it is impossible to be used alone（I.e. notOnly it can be rested the head on and human contact with waist, back-supported, the support of shoulder horizontal stripes are not contacted）, that is to say, that the invention belongs to original hairIt is bright, without background technology, back-supported is not sold, the back-supported that can independently use is not sold, does not more sell with the back of the bodyChange is by the back-supported at angle.
The backrest of present seat has a disadvantage that：1st, the back of the body of people thinks docile on backrest, can only change hip and be sitting in chairFront and back position on seat surface, is to ask for help to adapt to pre-adjusted backrest angle, is not that back adapts to people's change at any timeBy angle.2nd, the body wt on lumbar vertebrae top, backrest heavy burden very little is born a heavy burden by lumbar vertebrae entirely.When the 3rd, bending over, back is without supportPower.
The content of the invention
The purpose of the present invention is that design is a kind of：1st, it can be used alone（I.e. not with other supports in the backrest of seatContact can also be applied）With the back-supported of back of the body angle；2nd, hip are moved after seat surface is gone forward in travelling, and are leaned against in the invention,It is consistent all with the dorsal horn degree of people, back of the docile in body at any time；3rd, body part weight is born in the invention in travelling, and reduces waistVertebra and hip load；4th, travel in can activity bend over, the back of the body of the invention and people can not be separated, lessened fatigue；Bow and bend overStill it can lean on；5th, in travelling on the premise of not adjusting, driver can sitting be driven at any time, semi-lying is driven.
The technical solution adopted for the present invention to solve the technical problems is that have：With exclusive use function with the back of the body angle back of the bodyPortion's supporter 1, changes angle according to by angle, reaches goal of the invention and following beneficial effect above.
The beneficial effects of the invention are as follows：Hip are changed in everyone, the life style of daily some time, traveling in seat surfaceUpper movable, the invention is consistent with the dorsal horn degree of people；Reduce lumbar vertebrae and the halfload of hip one；Can activity bend over, mitigate it is tiredLabor.In traveling on the premise of not adjusting, driver sitting can drive at any time（See Fig. 2）, semi-lying drive（See Fig. 3）, it is seen thatMeaning is big, the invention belongs to original invention, the invention of great significance, because it changes the life of some time for each person every day, Ke YiheStirrup invention is mentioned in the same breath, and user is never abandoned with once.
Brief description of the drawings
The present invention is further described with reference to the accompanying drawings and examples.
Fig. 1 is the stereoscopic photograph of the present invention.
Fig. 2 is the photo driven using sitting of the present invention.
Fig. 3 is the photo driven using semi-lying of the present invention.
Embodiment
Have in Fig. 1 and being connected with back of the body angle back supports 1 with seat contact 3 for function is used alone.With listThe use of function is solely to be rotated by axle 2 with back of the body angle with back of the body angle back-supported 1.With exclusive use function with the back of the body angle back of the bodyThe axle 2 that portion's supporter 1 is rotated is at the back of people（Above waist, below shoulder, it is called back）, horizontal positioned, with the back of the body change lean onAngle, is as can be seen from Fig. arc with being overlooked with back of the body angle back supports 1 for function is used alone, so can be with hiddenAxle, mainly effect are good, people when leaning against in the axle center of axle 2, preferably, during manufacture, arc bottom is slightly lower than axle center to effect.Seat connectsThe upper and lower ends of contact 3 apart from axle center distance, it is one long one short, be so easy to high high adjustment, that is to say, that body is highPeople, long head is placed on following, the short people of body, and brachycephaly is placed on following.The invention is put on the seat can be to use, it is not necessary to tiesTie up.Seat contact 3 typically uses plate, naturally it is also possible to using frame etc., the size of plate suqare, thus it is possible to vary elastic size（Because the backrest of seat is just with elasticity, the big elasticity of contact surface is reduced）.
Fig. 2 is the state that sitting is driven.
Fig. 3 is the state that semi-lying is driven.As can be seen that upper body major part weight with the back of the body by becoming with exclusive use functionAngle back supports 1 are held up, the meaning not exclusively " leaned on ", also " are held in the palm ", reduce lumbar vertebrae and hip load, control it is goodWords, lumbar vertebrae can realize zero load.Hip are sitting in seat surface any point, it is top after, be used alone function with back of the body angleBack supports 1 all ensure consistent with the dorsal horn degree of people, are pasted at any time with back of the body angle back supports 1 with exclusive use functionThe back in body is taken, still there is support force at back during movable waist.In traveling, on the premise of not adjusting, driver can be withSitting is driven at any time, semi-lying is driven, and is additionally included in certainly between both excessively, is rested in any point, it is seen that meaning is big.
Be used alone function implication --- the back of the body of-people, which only contacts the support, to be exactly not contact seat to useShoulder support and following lumbar support behind chair can be to use, and this point is as can be seen from Figures 2 and 3.In addition, differenceLumbar support and back-supported, can mainly see be used alone, it is clear that above lumbar support, be not all right by body support's.
The implication --- --- of back-supported be horizontal positioned, the axle center of the axle 2 of stress（That is stress point）At back, it is called the back of the bodyPortion is supported.Obviously, axle center is called lumbar support in waist, and axle center is called shoulder support in shoulder.
Angle is leaned on the implication --- -- back supports 1 for carrying on the back angle, is changed according to the back of the body of people.
Shoulder horizontal stripes support two shoulders of implication --- -- and its between support.
