Description
Technical field
The present invention relates to automotive seating art fields, and in particular to a kind of car seat back frame and the linkage of seat frame skeleton
Regulating mechanism.
Background technique
As automobile is universal in life, more stringent requirements are proposed to car comfort by people, and automotive seat is vapour
Important component on vehicle, comfort level, the structure and function of automotive seat by bus for directly affecting driver and passenger are designed to pass
Important, the user of different height is different to the requirement for height of automotive seat, in order to improve the versatility of automotive seat, improves every
The riding comfort of position user, the backrest angle and seat basin height of automotive seat can be adjusted separately.When people need to adjust
When whole posture rest, the form that this backrest and seat basin are adjusted respectively then seems that some are cumbersome, and due to second being adjusted respectively
Section user may need repeatedly to adjust respectively to find a pleasant rest angle, thus a it is necessary to develop
The structure of backrest and the linkage of seat basin.
Use new content
In view of this, the present invention provides a kind of car seat back frames and seat frame skeleton linkage adjustment mechanism.
Its technical solution is as follows: a kind of car seat back frame and seat frame skeleton linkage adjustment mechanism, including leans on spine
Frame and seat frame skeleton, wherein the seat frame skeleton includes that seat frame side plate, the two sides difference of the backrest frames is arranged in two pieces of faces
Rear portion by articulation piece and two block frame side plates is hinged, and seat pelvis frame is equipped between two pieces of seat frame side plates, and key exists
In: the rear portion of the seat pelvis frame and the corresponding seat frame side plate are hinged, and the front of the seat pelvis frame passes through height-regulating mechanism
It is connected with the front of the corresponding seat frame side plate；
The backrest frames are connected with power mechanism, which drives the backrest frames to turn centered on articulation piece
The dynamic angle so as to adjust the backrest frames, the power mechanism also drive the height-regulating mechanism movement so as to adjust the seat
The height of pelvis frame front.
By adopting the above technical scheme, power mechanism can drive backrest side plate to rotate around articulation piece, so as to adjust backrest frames
Angle, while power mechanism also pass through driving height-regulating mechanism movement, and then drive seat pelvis frame front be raised or lowered
To achieve the purpose that adjust its height, this structure and traditional structure for individually adjusting seat back angle, cushion height
It compares, eliminates traditional angle adjustor, structure is simple, cost is lower, good reliability, and can adjusting angle of backrest and seat basin simultaneously
Highly, convenient for users to being quickly adjusted to most suitable resting state.
As preferred:
Above-mentioned height-regulating mechanism includes side plate connecting plate, and the seat frame side plate is equipped with the first limit hole of bar shaped, this first
Limit hole is obliquely installed, and the front end of its high-end close seat frame side plate, is equipped with limited post on the side plate connecting plate, should
