Description
Technical field
The invention belongs to auto parts machinery field, specifically refer to a kind of backrest lifting unlocking type truck central seat.
Background technology
Motor-vehicle seat system is used in car support to driver, and is ensureing convenient turnover and driving behaviour
Thering is provided effective constraint on the premise of work, seat system is it would be desirable to provide controllability expected from driver and long-distance
The comfort driven.In closing of the door state, in seat whole regulation stroke, the operation of seat system should
This is suitable to all bodily form motorists and carries out control manipulation intuitively.Compare general truck and only have positive front passenger's seat
Chair, the configuration of central seat adds the quantity of the taken member of truck, significantly more efficient utilize car in empty
Between.
The automotive seat now used is handle locking type seat, and its ingredient includes that backrest, seat are sat
Pad, mounting bracket, recliner, regulation handle, wherein recliner is real by regulation handle
The existing turnover of backrest, the function of locking.
Handle locking type seat, seat needs recliner, relatively costly；The position of central seat
Put and structure be unfavorable for the layout of adjusting means, easily cause handle regulation power less with interior trim gap relatively greatly,
It is unfavorable for the problems such as operation.
Summary of the invention
It is an object of the invention to provide a kind of plug-in locking structure, make seat not increase recliner
In the case of, the locking and the lifting that can be achieved with backrest unlock；Seat cost, weight is made to be controlled；
Limit without regulation handle, make the layout of seat can not consider the requirement of working place.
The present invention is achieved by the following technical solutions:
Truck seat capable of being unlocked through lifting and pulling of backrest, includes Chain cushion, the cushion skeleton knot of support seat cushion
Structure, backrest, the backrest frames structure of support seat chair back；
Described cushion skeleton is each provided with arc convex, in described projection with the both sides of backrest frames contact edge
The face that line extended line is formed with backrest frames and backrest is parallel；
The limit shaft vertical with the face of arc convex it is provided with on described arc convex, convex with arc at limit shaft
It is provided with gathering sill between the top risen；The center line of described gathering sill, spacing axis of spindle and arc convex
Center line overlaps；
The nearly lower end, two sides of described backrest frames is respectively arranged with rotary shaft, and rotary shaft is joined with gathering sill
Close, to ensure that backrest frames can rotate around rotary shaft limited angle；
The lower end of two sides of described backrest frames is respectively arranged with stopper slot structure, and limit shaft can enter
In stopper slot.
Described gathering sill is long waist type.
Described arc convex is inserted into inside two sides of backrest frames.
Described stopper slot is set to arc angling close to backrest side end in the side of backrest frames.
The degree of depth of stopper slot is more than the diameter of axle length of limit shaft.
The lower surface of cushion skeleton is provided with mounting bracket.
The invention has the beneficial effects as follows:
By rotary shaft and limit shaft, coordinating of stopper slot realizing the locking of backrest；After backrest upwards lifts,
Latch functions disappears, and backrest can freely put down.Need not recliner and i.e. realize the turnover of backrest, lock
Only function；Be conducive to the clearance control of seat cost control and lightweight, beneficially seat and its Surrounding Parts.

Detailed description of the invention
Describe technical scheme by the following examples in detail, it should be appreciated that following reality
It is only exemplary for executing example, is only capable of for explaining and illustrate technical scheme, and is not to be construed as
Restriction to technical solution of the present invention.
As it is shown in figure 1, truck seat capable of being unlocked through lifting and pulling of backrest, include Chain cushion 4, support seat chair
Cushion skeleton 7 structure of pad, Chain cushion 4 is fixed in cushion skeleton 7 structure.Backrest 1,
Holding backrest frames 6 structure of backrest, backrest 1 is fixed in backrest frames 6 structure；Medicated cushion bone
Shelf structure and backrest frames structure are metal material manufacture.
Described cushion skeleton 7 is each provided with arc convex 10 with at least both sides of backrest frames 6 contact edge,
In other embodiments, it is also equipped with arc convex in centre；The center line extended line of described arc convex with lean on
The face that spine frame and backrest are formed is parallel, so ensure that the angle between backrest and Chain cushion
Degree, is beneficial to conform to the design of Human Physiology curve.Each arc convex is all in parastate, and arc convex is plate
Formula structure.Described arc convex 10 is inserted into inside two sides 11 of backrest frames 6.
The limit shaft 9 vertical with the face of arc convex, both sides limit shaft it is provided with on described arc convex 10
Top wire length more than the length of backrest frames dual-side outer surface line.Convex with arc at limit shaft 9
Rising and be provided with gathering sill 13 between the top of 10, described gathering sill 13 is long waist type.Described gathering sill
The center line of center line, spacing axis of spindle and arc convex overlaps；
The nearly lower end, two sides 11 of described backrest frames 6 is respectively arranged with rotary shaft 8, and rotary shaft is permissible
It is an axle construction, it is also possible to being two axle construction, rotary shaft 8 coordinates with gathering sill 13, rotary shaft energy
Enough in External Force Acting lower slider in gathering sill, rotary shaft is to ensure that backrest frames can be around rotary shaft finite angle
Degree rotates；
The lower end of two sides 11 of described backrest frames 6 is respectively arranged with stopper slot 12 structure, limit shaft
9 can enter in stopper slot 12.Close to seat back side in the side of described stopper slot and backrest frames
End is set to arc angling.
The degree of depth of stopper slot, more than the diameter of axle length of limit shaft, prevents the abjection of limit shaft.
The lower surface of cushion skeleton is provided with mounting bracket.
As shown in Fig. 2 a to Fig. 2 d, this seat is that backrest lifts unlocking type seat；It is primarily adapted for use in truck
Between seat；In use state, realize backrest by the cooperation of rotary shaft 8, limit shaft 9 and stopper slot 12
Locking；During backrest to be put down, backrest upwards lifts, and makes rotary shaft 8 prolong gathering sill 13 and moves up,
Limit shaft 9 departs from stopper slot 12, and backrest can freely put down.
Although an embodiment of the present invention has been shown and described, for those of ordinary skill in the art
For, it is possible to understand that without departing from the principles and spirit of the present invention can be to these embodiments
Carry out multiple change, revise, replace and modification, the scope of the present invention by claims and etc.
With limiting.
