Abstract
The utility model relates to a seat and a passenger car using the same. The seat comprises a backrest and a seat cushion, wherein the seat cushion is arranged under the backrest and can be turned up and down, the seat further comprises a guiding structure, and the guiding direction of the guiding structure stretches along the vertical direction. The backrest is mounted on the guiding structure in a guiding and moving mode. The seat further comprises a transmission rod, wherein two ends of the transmission rod are respectively connected with the backrest and the seat cushion in a hinged mode through an upper hinge structure and a lower hinge structure. The seat cushion, the transmission rod and the backrest form a slider-crank mechanism. The sum of the distance between the end portion of a free end of the seat cushion and a rotating axis of the lower hinge structure and the distance between the end portion of the lower end of the backrest and a rotating axis of the upper hinge structure is not larger than the distance between the rotating axis of the lower hinge structure and the rotating axis of the upper hinge structure. By means of the seat, the problem that when an existing seat is in a folding state, the seat cushion and the backrest occupy large space due to the fact that the thickness of the seat cushion and the thickness of the backrest are overlapped in the front-back direction is solved.

Described seat also comprises seat frame, and described guide frame is arranged on the described seat frame, and described cushion is hinged and connected by cushion articulated structure and described seat frame and realizes spinning upside down of described cushion.
Described cushion articulated structure is arranged at an end of supporting or opposing with described free end on the described cushion.
When described seat also is included in described cushion and turn to level attitude described cushion is remained on the maintenance structure of level attitude.
Described guide frame comprises the vertical guide groove that guide direction is extended along the vertical direction, be provided with the track adjusting wheel or the guidepost that cooperate with the cell wall guiding of described vertical guide groove on the described backrest, described maintenance structure is made of the cell wall of the end, lower end of the guiding stroke of described vertical guide groove.
The technical scheme of the utility model microbus is:
Passenger vehicle, comprise car body and the upper seat that arranges thereof, described seat comprises the cushion that spins upside down that backrest and below thereof arrange, described seat also comprises the guide frame that guide direction is extended along the vertical direction, being assemblied on the described guide frame of described backrest guiding movement, described seat comprises that also two ends are respectively by upper, lower articulated structure and described backrest, the drive link that cushion is hinged and connected, described cushion, drive link and backrest have consisted of slider-crank mechanism, the free end end of described cushion apart from the end, lower end of the distance between the pivot center of described lower articulated structure and described backrest apart between the pivot center of described upper articulated structure apart from sum be not more than described on, distance between the pivot center of lower articulated structure.
Described seat also comprises seat frame, and described guide frame is arranged on the described seat frame, and described cushion is hinged and connected by cushion articulated structure and described seat frame and realizes spinning upside down of described cushion.
The front door along the left and right directions extension that described Vehicular body front is provided with the Qianmen and communicates with described Qianmen, described seat frame is arranged on the rear side conduit wall of described front door, and the pivot center of described first, second and third articulated structure all extends along left and right directions.
When described seat also is included in described cushion and turn to level attitude described cushion is remained on the maintenance structure of level attitude.
Described guide frame comprises the vertical guide groove that guide direction is extended along the vertical direction, be provided with the track adjusting wheel or the guidepost that cooperate with the cell wall guiding of described vertical guide groove on the described backrest, described maintenance structure is made of the cell wall of the end, lower end of the guiding stroke of described vertical guide groove.
The beneficial effects of the utility model are: when needs pass through for corresponding pedestrian seat is folding, turnover cushion makes progress, drive link transmission and make backrest along the guide frame upward movement, cushion, drive link and backrest have consisted of slider-crank mechanism, in the upward movement process of backrest, because the free end end of cushion is apart from being not more than apart from sum between end, the lower end distance pivot center of upper articulated structure of the distance between the pivot center of lower articulated structure and backrest, distance between the pivot center of lower articulated structure, can abdicate a space that allows cushion be turned into vertical state behind the backrest upward movement, seat is when folding finishing like this, cushion and backrest all are on the same vertical facade, the thickness of cushion and backrest can be not overlapping on fore-and-aft direction, greatly saved the space.
