Abstract
The invention discloses a folding automobile seat and a four-connecting rod mechanism for supporting the seat; the four four-connecting rod mechanism comprises a connecting rod, a seat mounting bracket, a right-and-left connecting rod, a fore-and-aft connecting rod and a locking mechanism; one end of the connecting rod is connected with the seat mounting bracket through a pin; the other end of the connecting rod is connected with the right-and-left connecting rod and the fore-and-aft connecting rod through pins; and the locking mechanism is arranged on one of two rear connecting rods and is used for locking the connecting rod when the seat is in a riding state. The lower part of the seat is provided with the four-connecting rod mechanism; when the seat is in the riding state, the four-connecting rod mechanism is locked; a cushion is in the highest position; when the seats of the rear row are not used and the storage space is needed to increase, the seat backs can be set level; and after the four-connecting rod mechanism is unlocked through an unlocking part, the four-connecting rod mechanism drives the folded seats to move forwards and reduces height of the seats at the same time. The four-connecting rod mechanism furthest broadens the space of a boot, keeps the decoration of the automobile neat and attractive and brings great convenience for a user.
Description
Technical field
The present invention relates to automotive seat, particularly relate to a kind of adjustable automotive seat four-bar linkage.
Background technology
Some automobile need fall back seat when increasing storage space at present, just directly back of seat was set level, and can not utilize interior space to greatest extent; Or after cushion vertically need being overturn forward, could realize the fold-flat of back backrest, and this brings inconvenience not only for user's use, and because the volume of cushion has taken certain space, reduces storage space, and the interior trim effect is also untidy.
Summary of the invention
Problem to be solved by this invention is that the back seat of automobile is just directly set level back of seat and increased storage space, can not utilize the space in the car to greatest extent.
For addressing the above problem, the invention discloses a kind of four-bar linkage, comprise: connecting rod, chair mounted support, left and right sides pipe link, front and back pipe link and lockout mechanism, one end of connecting rod is connected by pin with the chair mounted support, the other end is connected by pin with all around pipe link, lockout mechanism is installed on one of them of two rear linking rods, is used for being in lock link when taking state at seat.Lockout mechanism comprises the release drawstring, is used for the locking of unlocked mechanism to connecting rod.
Divide at seat and to put above-mentioned four-bar linkage, when seat when taking state, four-bar linkage is lockable, cushion is in the extreme higher position; When back seat does not use, when needing to increase storage space, then can earlier back of seat be set level, by separate lock assembly with the four-bar linkage release after, four-bar linkage reduces height when driving seat reach after folding.
The present invention increases by a four-bar linkage to realize that the height of seat reduces under Chain cushion, the space that makes full use of in the car increases storage space.And after can well realizing that second and third row's seat fell simultaneously, can keep at grade with baggage compartment floor, when expanding trunk space to greatest extent, keep the neat and artistic of car interior trim, bring great convenience to the user, and but by release drawstring release four-bar linkage just, operation is very easy.

The specific embodiment
Below in conjunction with accompanying drawing the present invention is specifically described.
As shown in Figure 1, 2, the automotive seat four-bar linkage comprises: connecting rod 4, chair mounted support 5, left and right sides pipe link 7, front and back pipe link 9 and lockout mechanism 8.One end of four connecting rods 4 and chair mounted support 5 are connected by pin, and the other end and pipe link 7,9 are connected by pin, on one of them of two rear linking rods 4 lockout mechanism 8 are installed.
As shown in Figure 3, four-bar linkage is arranged under the Chain cushion 3, and is fixed on the floor by chair mounted support 5.Seat is being taken under the state, and four connecting rods 4 simultaneously by left and right sides pipe link 7, guarantee that seat does not shake by lockout mechanism 8 lockings when taking state.
The seat that shown in Figure 4 is behind the backrest fold-down is set level after with back of seat 2 releases by pushing back of seat unlock button 1, and this moment, four-bar linkage also was in lockup state.
Fig. 5 and Fig. 6 are seat under the storing state and four-bar linkage, after back of seat 2 is set level, the locking of untiing 8 pairs of four connecting rods of release mechanism by the release drawstring 6 that is provided with on the lockout mechanism 8, this moment, four connecting rods can center on and base mounting bracket bonded assembly pin, and rotate with pipe link 7,9 bonded assembly pins, seat after then folding can be realized the reduction of height by the effect of four-bar linkage.
