Description
Technical field：
The invention belongs to arta vehicle seat unit technical field is and in particular to a kind of seat folding and moving forward that leans forward fills
Put.
Background technology：
The automotive seat of prior art enters system soon and mainly unlocks backrest, and the flip angle using backrest by drag-line
Spend and to drive unlocking sliding rail.The limited space of the heel row personnel turnover that this structure can be provided by, is not easy to get on or off the bus, and assembles
Complex process, the space that can vacate is extremely limited, and resultant effect is not good.
Prior art also has improved automotive seat easily to enter structure, such as Chinese Patent Application No.：
201110274054.3, the Chinese patent application of entitled " seat-back release system of the automotive seat easily entering ", public
Open a kind of fast entrance structure of automotive seat, the backrest motion controller of this application is arranged on the seat in vehicle
On, seat includes seat base and backrest, and backrest is configured to vertically make with respect to seat base
With position with lean forward and carry out pivoting movement between the position easily entering.The structure of this patent application is only backrest
With respect to base rotation that is to say, that it has the certain significance for the space release of seat upper portion, but it is under seat
Half portion is still not changed in, and lower half and Free up Memory easily enter unrelated, and the special complicated, operating cost of the structure of this application
Power, the comprehensive significance of enforcement is little.
Content of the invention：
The purpose of the present invention is, overcome the automotive seat that prior art exists fast entrance system structure complicated, heavy and
The little defect of effect, provides a kind of seat unit, and this device can lean forward to fold and move forward and discharge as far as possible big space to obtain
Come in and go out for heel row personnel, and this device rapid operation.
The purpose of the present invention is achieved through the following technical solutions.
A kind of automotive seat leans forward folding adjusting means, including seat basin skeleton, backrest frames and swing handle, it is characterized in that, this
Device is additionally provided with the sliding track mechanism being connected in floor compartment, and sliding track mechanism includes trapped orbit and slide rail；Slide rail, swing handle, seat
Basin skeleton and backrest frames collectively form as a quadric chain, swing handle and seat basin skeleton, seat basin skeleton and backrest frames,
Backrest frames are connected through the hinge respectively with slide rail, slide rail and swing handle；This device is provided with locking mechanism.
When backrest frames are opened with seat basin skeleton, slide rail and trapped orbit simultaneously close and slide rail is in fixing guide rail back-end location
When, it is to be in normal operating condition for device, also referred to as rear extreme position, now locking mechanism locking；When backrest frames are to seat basin
Skeleton leans forward folding, when slide rail and trapped orbit open and slide rail is in fixing guide rail front position, is for providing rear passenger
Fast enter use state, also referred to as front extreme position, now locking mechanism unclamp.
When swing handle rotate counterclockwise, quadric chain action, device rotates and by means of artificial promotion from rear extreme position
It is transformed into front extreme position, now device is lifted entirely around the hinge connection of slide rail and swing handle, the space at seat rear
Expand, be easy to rear passenger and get on or off the bus.
By the structure design of sliding track lock and double leval jib, realize when sliding track lock is in released state, make a basin skeleton with
Slide rail separates, thus seat can be advanced longitudinally forward, produce additional distance, vacates bigger space and meet heel row personnel's
Turnover.
Preferred version, described locking mechanism includes sliding track lock, and sliding track lock has one end to be connected to the lower end of backrest frames, another
End is releasably connected with the trapped orbit being connected in floor compartment.When the seat is folded, sliding track lock reaches released state, sliding
Rail obtains the longitudinal degress of feedom.
Preferred version, in described all hinges junction, wherein at least has at one and is provided with wind spring.Wind spring is located at seat
On certain point of rotation of fold mechanism, provide power-assisted to during seat rotation lifting, make operation light.
Preferred version, described wind spring is arranged on the hinge connection of backrest frames and slide rail；Wind spring is plane scroll spring,
The mounting means of this plane scroll spring is fixed for outer end, inner revolution.Learnt according to theoretical derivation computing, outer end is fixing inner
The rigidity big 25% of the plane scroll spring of ratio of rigidity the inner fixed outer ends revolution of the plane scroll spring of revolution, in other words,
Same its moment of torsion of angular deformation amount wants big 25%.
Preferred version, described plane scroll spring is the plane scroll spring of variation rigidity, and its outermost end has one section of rigidity relatively
Low breeze way.When locking mechanism just releases, due to the unexpected release of wind spring moment of torsion and the superposition force of operator, make phase
Close and produce angular acceleration mutation between tumbler and cause to collide, the relatively low breeze way of rigidity of setting wind spring can play mitigation collision
Cushioning effect.
Preferred version, present basin skeleton is provided with torsion spring with the junction of backrest frames, and torsion spring has a torque arm to be fixed on
On seat basin skeleton, another torque arm is fixed on backrest frames.Torsion spring is located in the rotary shaft of backrest, adjusts in backrest
There is provided during section and reply power-assisted, make backrest reply operation easily.
Preferred version, is connected with some installing plates in present basin skeleton, seat basin skeleton adopts pipe assemble welding mode.This
Plant structure and can improve the intensity of basin skeleton and stability.
Preferred version, is connected with the gag lever post toward upper process in the front end of trapped orbit, and gag lever post is front lower with seat basin skeleton
The inconsistent position-limit mechanism being advanced to forefront position for constituting seat in bottom.
The invention has the beneficial effects as follows：
1st, seat leans forward and folds extension heel row personnel turnover space；
2nd, when seat by the folding movement that leans forward to rearmost position when, slide rail is separated with trapped orbit makes seat overall
Move forward to expand bigger space；
3rd, setting wind spring makes lifting of folding and seat lighter；
4th, setting torsion spring makes backrest reply lighter；
5th, lean forward the four-bar linkage structure of fold mechanism, rotate easily, quick；
6th, four-bar linkage structure reduces cost, saves installation time；
7th, wind spring has buffering segment structure, it is to avoid the impingement phenomenon of starting stage of leaning forward；
8th, wind spring outer end is fixed, the inner is turned round, and lifts moment of torsion；
9th, it is provided with gag lever post and limits seat and lean forward the forward extreme position of folding；
10th, intensity and stability are improved using pipe assemble welding mode by installing plate and seat basin skeleton.
