Description

A kind of adjustable height bogey
Technical field
The present invention relates to automotive seat design field, specifically a kind of adjustable height bogey.
Background technology
Ergonomics is widely used in the design of automotive seat, but everyone body is different, so everyone is required also just different, current seat, still can feel to have a pain in the back at chaufeur after driving relatively for a long time, most chaufeur by waist beyond the Great Wall headrest alleviate and ache, and have a lot of seat to be all provided with headrest.For the chaufeur that waistline is smaller, the chaufeur that the height that they will pad up is often larger than waistline is lower, they just feel more comfortable like this, and for same chaufeur, its different sitting posture is also different to the height that headrest will pad up, but current headrest is all fixing mostly, the unadjustable height that it pads up, so be badly in need of the automotive seat that a kind of adjustable headrest paves height.
Summary of the invention
Technical matters to be solved by this invention be to provide a kind of reasonable in design, headrest can be regulated to pave the device of height, i.e. a kind of adjustable height bogey.
Technical matters to be solved by this invention realizes by the following technical solutions:
A kind of adjustable height bogey, comprises cushion, backrest, headrest and control apparatus.Be provided with inner chamber in described backrest, and backrest middle and lower part is provided with chute, described headrest is arranged in chute, and headrest is placed on front side of backrest, described control apparatus and headrest are hinged, and described control apparatus is arranged in the inner chamber of backrest, and control apparatus can regulate paving highly of headrest.The present invention can be used for automotive field, sits and supported weight for chaufeur or passenger.
Described control apparatus comprises adjustment handle, drive link, pillar, pipe link and Unidirectional movement mechanism, described adjustment handle is arranged on drive link one end, described drive link is provided with three pillars, one end of described pillar and pipe link is hinged, the other end and the headrest of described pipe link are hinged, and described Unidirectional movement mechanism is arranged on drive link one end.Rotate and regulate handle that headrest can be made close to the waist of chaufeur along chute, thus reach the object that adjustment headrest paves height.
Described Unidirectional movement mechanism comprises ratchet and pawl, described ratchet is provided with draw ring, and Unidirectional movement mechanism adopts ratchet and pawl arrangement, when chaufeur waist leans against on headrest, Unidirectional movement mechanism can make the motion of headrest in chute be limited, stop headrest to be retracted, thus realize the object of reverse locking, draw ring is used for releasing reverse motion, when draw ring is axially drawn out along drive link, ratchet departs from ratchet and engages, and when at this moment the waist of chaufeur is pressed against pillow backward, headrest is retracted along chute.
The invention has the beneficial effects as follows: the present invention has the advantages such as reasonable in design, cost be lower, can realize adjusting the object that headrest paves height, meet the demand of different crowd, be applied in automotive field as sat for automobile driver, then the waist effectively can alleviating chaufeur is ached.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is perspective view of the present invention;
Fig. 2 is main TV structure schematic diagram of the present invention;
Fig. 3 is the perspective view of control apparatus of the present invention;
Fig. 4 is the B-B structural representation of Fig. 3.
Detailed description of the invention
The technological means realized to make the present invention, creation characteristic, reaching object and effect is easy to understand, below the present invention being set forth further.
As shown in Figures 1 to 4, a kind of adjustable height bogey, comprises cushion 1, backrest 2, headrest 3 and control apparatus 4.Inner chamber is provided with in described backrest 2, and backrest 2 middle and lower part is provided with chute 201, described headrest 3 is arranged in chute 201, and headrest 3 is placed on front side of backrest 2, described control apparatus 4 is hinged with headrest 3, described control apparatus 4 is arranged in the inner chamber of backrest 2, and control apparatus 4 can regulate paving highly of headrest 3.
Described control apparatus 4 comprises adjustment handle 401, drive link 402, pillar 403, pipe link 404 and Unidirectional movement mechanism 405, described adjustment handle 401 is arranged on drive link 402 one end, described drive link 402 is provided with three pillars 403, described pillar 403 is hinged with one end of pipe link 404, the other end and the headrest 3 of described pipe link 404 are hinged, and described Unidirectional movement mechanism 405 is arranged on drive link 402 one end.Rotate and regulate handle 401 that headrest 3 can be made close to the waist of chaufeur along chute 201, thus reach the object that adjustment headrest 3 paves height.
Described Unidirectional movement mechanism 405 comprises ratchet 405a and ratchet 405b, described ratchet 405b is provided with draw ring 405c, Unidirectional movement mechanism 405 adopts ratchet and pawl arrangement, when chaufeur waist leans against on headrest 3, Unidirectional movement mechanism 405 can make the motion of headrest 3 in chute 201 be limited, headrest 201 is stoped to be retracted, thus realize the object of reverse locking, draw ring 405c is used for releasing reverse motion, when draw ring 405c is axially drawn out along drive link 402, ratchet 405a departs from ratchet 405b and engages, at this moment when the waist of chaufeur is pressed against pillow 3 backward, headrest 3 is retracted along chute 201.
During use, chaufeur adjusts the height that headrest 3 paves needed for self, rotate and regulate handle 401, regulate handle 401 to drive drive link 402 to move, drive link 402 drives pipe link 404, pipe link 404 drives headrest 3 to move along chute 201, now complete adjustment, unclamp adjustment handle 401, under the effect of Unidirectional movement mechanism 405, headrest 3 cannot be retracted, thus reaches the object of reverse locking.When chaufeur pulls draw ring 405c, the reverse locking effect of Unidirectional movement mechanism 405 was lost efficacy, and now chaufeur waist extruding headrest 3 can make headrest 3 retract.
The present invention has the following advantages:
(1) reasonable in design, cost is lower, convenient to operation;
(2) can realize adjusting the object that headrest paves height, meet the demand of different crowd, and the waist effectively can alleviating chaufeur be ached.
More than show and describe groundwork of the present invention, principal character and advantage of the present invention.The technical personnel of the industry should be understood; the present invention is not restricted to the described embodiments; the just principle of the present invention described in above-described embodiment and specification sheets; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.Application claims protection domain is defined by appending claims and equivalent thereof.
