Description
Technical field
The present invention relates to a kind of for the commutation seat in mass transportation facilities.
Background technology
With expanding economy, China is just experiencing the tide of urbanization, and the public transportation system in city is also faced with newly
Test, the riding comfort with regard to public transports such as city bus, subway, trains and the research of hommization also more next
More.And the design for large-scale mass transportation facilities and the man machine interface seat of general passenger also receives very big concern.
For example it is desirable to the seat of subway can commutate, thus passenger can with unrestricted choice towards direction, or be easy to be talked with friend
And carry out recreations.Existing seat capable of reversing in part high ferro at present, by rotating 180 ° of realities by seat around its center
Existing direction changes.But the tumbler of this seat is excessively heavy and loaded down with trivial details, high cost, switch operation is also relatively more painstaking, and
Floor space is larger, and needing to reserve enough spaces in installation process guarantees that seat can rotate, and is unsuitable for originally gathering around
Use in crowded compartment space.
Content of the invention
In order to overcome the commutation shortcoming that armchair structure is loaded down with trivial details, floor space is big in existing mass transportation facilities, this
Commutation seat in bright offer mass transportation facilities.
The technical solution used in the present invention is：
A kind of for the commutation seat in mass transportation facilities, including seat body and its support base, described seat this
Body includes seat, and described seat both sides are provided with handrail, are provided with backrest on rear side of described seat, and described backrest passes through changement and institute
The both sides stating seat connect, to drive described backrest to rotate around described seat；
Described changement includes constituting the first side link and second side link of four-bar mechanism with seat, backrest, described
First side link and the second side link intersect, the near-end of described first side link and the second side link respectively with described seat side
Side is hinged, and the far-end of described first side link and the second side link is hinged with the side of described backrest respectively, and the two of described backrest
Side is provided with draw-in groove, and the far-end of described first side link and the second side link is hinged with the groove inwall at described draw-in groove two ends respectively, institute
State draw-in groove and be respectively arranged at two ends with the termination limiting described first side link and the second side link inordinate rotation；
The two of described first side link and the equal length of the second side link, described first side link and the second side link are near
The mounting distance at end is less than the length of described first side link, the installation of two near-ends of described first side link and the second side link
Distance is less than the mounting distance of two far-ends；
Described backrest is provided with the draw ring being easy to overturn.
Beneficial effects of the present invention are embodied in：Only the transformation that backrest just can realize seat directions need to be rotated, lightly facilitate,
And it is not take up additional space, so that people can be freely changed towards direction as needed, meet personal needs it is adaptable to people
Flow is big, on the vehicle of the large-scale public transport such as the buses of narrow space, subway.

Specific embodiment
Referring to the drawings, a kind of for the commutation seat in mass transportation facilities, including seat body 1 and its support base 2,
Described seat body 1 includes seat 11, and described seat 11 both sides are provided with handrail 13, are provided with backrest 12, institute on rear side of described seat 11
State backrest 12 to be connected with the both sides of described seat 11 by rotating mechanism, to drive described backrest 12 to rotate around described seat 11；
Described changement includes constituting the first side link 14 and second side link of four-bar mechanism with seat 11, backrest 12
15, described first side link 14 and the second side link 15 intersect, the near-end of described first side link 14 and the second side link 15
Hinged with described seat 11 side respectively, the far-end of described first side link 14 and the second side link 15 respectively with described backrest 12
Side hinged, the both sides of described backrest 12 are provided with draw-in groove 122, and the far-end of described first side link 14 and the second side link 15 divides
Not hinged with the groove inwall at described draw-in groove 122 two ends, described draw-in groove 122 is respectively arranged at two ends with described first side link 14 He of restriction
The termination of the second side link 15 inordinate rotation；
Described first side link 14 and the equal length of the second side link 15, described first side link 14 and the second side link
The mounting distance of 15 two near-ends is less than length, described first side link 14 and second side link 15 of described first side link 14
Two near-ends mounting distance be less than two far-ends mounting distance；
Described backrest 12 is provided with the draw ring 121 being easy to overturn.
Draw ring 121 is pulled to be convenient for the switch operation of the present invention.
Described first side link 14 is identical with the structure of the second side link 15, size.
Described seat 11, backrest 12, the first side link 14 and the second side link 15 are linked together by way of hinged
Constitute double crank type changement, according to the operation principle of four-bar mechanism, the first side link 14 and the second side link 15 drive and lean on
The back of the body 12 turns to and uses position.Described backrest 12 is provided with two draw rings 121, is easy to pull backrest 12 to commutate.Described backrest 12
The draw-in groove 122 that both sides are provided with, described first side link 14 and the second side link 15 are hinged with groove inwall, go to use in backrest 12
The motion further of the first side link 14 or the second side link 15 is limited by the termination at draw-in groove 12 two ends, thus realizing during position
Positioning function.
During commutation, pull draw ring 121 backrest 12 is rotated up, when turning to certain position, the termination of draw-in groove 122 with
The side link being now placed in lower section is conflicted, and continues motion to limit this side link, thus reaching the purpose of positioning, so far, that is, complete
Become the switch operation of seat.
Especially, by adjust the first side link 14 and the second side link 15 mounting distance on described seat 11,
The length of one side link 14 and the second side link 15, the length of draw-in groove 122 and thickness, can adjust between backrest 12 and seat 11
Angle, thus reaching the desired position of user.
Content described in this specification embodiment is only enumerating of the way of realization to inventive concept, the protection of the present invention
Scope is not construed as being only limitted to the concrete form of embodiment statement, and protection scope of the present invention is also and in people in the art
Member according to present inventive concept it is conceivable that equivalent technologies mean.
