Detailed description of the invention
The utility model is further described with specific embodiment below in conjunction with accompanying drawing, see Fig. 1-Figure 15:
Vehicular seats seat cushion turning control mechanism, comprise backrest frames 1 and seat cushion framework 8, the downside of described seat cushion framework 8 is hinged on the downside of backrest frames 1, the downside of backrest frames 1 is hinged with the latch 7 of lower end with lock groove 10, locking extension spring 2 is provided with between backrest frames 1 and latch 7, the rear portion of seat cushion framework 8 be fixed with seat cushion framework 8 rotate forward pack up after be stuck in locking tooth 11 on lock groove 10, the radius of turn of locking tooth 11 end is greater than the radius of turn of latch 7 outer end, seat cushion framework 8 is packing up in the anglec of rotation put down, the outer end points of locking tooth 11 and the rotational trajectory of the outer end points of latch 7 have twice crossing, intersection point is A, B two point.
The jointed shaft 12 of above-mentioned seat cushion framework 8 is positioned at the upside of the locking pin 13 of latch 7, when seat cushion framework 8 is positioned at seating position (level attitude), locking tooth 11 be positioned at the downside of latch 7 and the upper end of locking tooth 11 higher than lock groove 10, the jointed shaft 12 of seat cushion framework 8 and locking tooth 11 are positioned at the side of the locking pin 13 of latch 7.
When above-mentioned seat cushion framework 8 is positioned at and packs up (vertically) or put down (level) position, the axis of locking extension spring 2 is all positioned at the lower right side of latch 7 locking pin 13.
Above-mentioned seat cushion framework 8 by pack up to put down be less than 90 degree, be greater than in the anglec of rotation G of 70 degree, the rotational trajectory of the outer end points of locking tooth and latch end points outward have twice crossing, intersection point is A, B 2 point.
The downside of above-mentioned backrest frames 1 is fixed with locking bracing frame 3, and described latch 7 is hinged on locking bracing frame 3.
The material of above-mentioned latch 7 is powdered metallurgical material, and subsequent heat treatment, take into account precision, durability and intensity.
The lower end of above-mentioned backrest frames 1 is hinged on seat base, backrest frames 1 and be provided with backrest frames 1 flip angle setting device between seat base.
Details are as follows for working process of the present utility model:
A pair hinge hole is arranged at seat cushion framework 8 rear of seat, and seat cushion freely can be rotated around jointed shaft 12.On seat back-rest framework 1, fix a latch 7, this latch can rotate around locking pin 13 simultaneously, and the predetermincd tension of the locking extension spring 2 be connected with backrest frames by an one end.
In the locking stage: when seat cushion slowly rises, seat cushion framework 8 slowly slides to the lock groove (engagement position) of latch 7, until the locking tooth 11 of seat cushion framework snaps in the lock groove 10 of latch 7, and sends click sound simultaneously.Now the pivotal degree of freedom of seat cushion framework 8 receives constraint: on the one hand, latch 7 has blocked seat cushion framework 8 makes it not fall after rise downwards, seat cushion has been rotated to the position towards backrest and has mutually compressed (see Fig. 5: backrest border 21 and seat cushion border 22 interference portion) with back cushion on the other hand, seat cushion like this rotates up and down and receives constraint, and seat cushion is in lockup state.
Released state: see Fig. 8-Fig. 9, at the front portion of seat cushion force F, overcome the screen resilience of back cushion to seat cushion if continue, seat cushion can continue to rotate to backrest, and latch 7 and seat cushion framework can continue relative sliding, until latch 7 and seat cushion framework disengage.Now latch 7 returns back to initial rest position because of tension spring force.Along with the return of latch, the downward slew constrained releasing of seat cushion, seat cushion can freely fall after rise forward, and seat cushion unlocks.
Reseting stage: see Figure 10-Figure 12, along with the falling forward of seat cushion, seat cushion framework 8 meets with the latch 7 of balance position again, and drive latch 7 to leave balance position to rotate backward (Figure 10), be returned to again balance position (Figure 11) until depart from, the upset locking for second leg is prepared (Figure 12).So far seat cushion completes the action of a upset locking and unblock.
Lockup state under backrest different angles: from the locking stage, the rotation of seat cushion receives the constraint of back cushion and latch 7, when backrest is in different angles, back cushion and latch 7 follow backrest to rotate (latch 7 be fixed on backrest frames 1), therefore above-mentioned restrained condition is consistent under the different angles of backrest, namely when backrest is in different angles, the locking (three kinds of lockup states as Figure 13-Figure 15) that seat cushion can be stable.
Above-described embodiment is only preferred embodiment of the present utility model, not limits protection domain of the present utility model according to this, therefore: all equivalence changes done according to structure of the present utility model, shape, principle, all should be covered by within protection domain of the present utility model.
