Abstract
The invention discloses a back-row seat backrest overturning unlocking mechanism. The back-row seat backrest overturning unlocking mechanism comprises a left backrest unlocking pulling rope, a right backrest unlocking pulling rope, a pulling ring, a pulling ring support, an unlocking pulling band, a T-shaped unlocking handle, a handle installation support and a handle return tension spring. The pulling ring support is fixedly installed on an upper transverse pipe of a backrest. The upper end of the unlocking pulling band penetrates through the pulling ring support to be connected with the pulling ring, and the lower end of the unlocking pulling band is hinged to the tail of the T-shaped unlocking handle. The middle of the head of the T-shaped unlocking handle is hinged to the handle installation support. The handle installation support is fixedly installed in a backrest frame. The upper end of the left backrest unlocking pulling rope is connected to one end of the head of the T-shaped unlocking handle, and the upper end of the right backrest unlocking pulling rope is connected to the other end of the head of the T-shaped unlocking handle. The lower end of the left backrest unlocking pulling rope and the lower end of the right backrest unlocking pulling rope are connected with floor locks on the corresponding sides of the backrest respectively. As the motion lever principle is adopted, much less effort is needed for the unlocking operation; the unlocking operation can be completed through one hand and thus is more convenient; the potential safety hazard of hand clamping does not exist.
Description
Technical field
The present invention relates to automotive seating art field, be specifically related to a kind of backrest for back seat upset unlocking structure.
Background technology
As shown in Figure 3, existing back seat backrest upset release mechanism is attacker's formula structure, primarily of attacker's plastics solution lock box 3, separates lock box metal bracket 4, backrest unblock stay cord left 1 and right 2 compositions of backrest unblock stay cord.Attacker's plastics solution lock box is fixedly mounted on the top of back of seat by separating lock box metal bracket, backrest unlocks in the upper end access attacker plastics solution lock box that stay cord is left, backrest unlocks the stay cord right side, the lower end that backrest unlocks a stay cord left side is connected with the floor latch on the left of back of seat, and the lower end that backrest unlocks the stay cord right side is connected with the floor latch on the right side of back of seat.
During unblock, the hand of operator pulls attacker's plastics solution lock box, and unlocks by two the floor latch that stay cord pulls respective side respectively, thus realizes unlocking.The subject matter that this structure exists is: (1) operation is not laborsaving, after pulling attacker's plastics solution lock box, needs other hand application force back of seat, and two hands coordinate the upset that can realize backrest; (2), there is potential safety hazard in the easy tong of attacker's formula structure; (3) when back of seat is down flat forward, people stands in when boot pulls attacker's plastics solution lock box very inconvenient, and also need both hands to coordinate, operation easier is large simultaneously.
Summary of the invention
The present invention aims to provide a kind of release mechanism for the upset of back seat backrest, has safety of operation, laborsaving, feature easily.
For this reason, the technical solution adopted in the present invention is: a kind of back seat backrest upset release mechanism, comprise backrest and unlock a stay cord left side and the backrest unblock stay cord right side, also comprise draw ring, draw ring support, unlock drawstring, "T"-shaped release lever, handle mounting bracket and handle returning pull-spring, described draw ring support is fixedly mounted on the upper lateral tube of backrest, the upper end unlocking drawstring is connected with draw ring through draw ring support, it is hinged that the lower end of unblock drawstring and the afterbody of "T"-shaped release lever pass through the second hinge-point, the middle position of "T"-shaped release lever head is hinged on handle mounting bracket by the first hinge-point, handle mounting bracket is fixedly mounted in the skeleton of backrest, the upper end on a described backrest unblock stay cord left side is connected to one end of "T"-shaped release lever head, the upper end on the backrest unblock stay cord right side is connected to the other end of "T"-shaped release lever head, it is left that backrest unlocks stay cord, right lower end is connected with the floor latch of backrest respective side respectively, when pulling draw ring, draw ring pulls "T"-shaped release lever to rotate around the first hinge-point by unlocking drawstring, it is left that "T"-shaped release lever pulls backrest to unlock stay cord, part on the right side and do not rotate towards the direction away from each self-corresponding floor latch, after unclamping draw ring, "T"-shaped release lever self-return under the effect of handle returning pull-spring.
Beneficial effect of the present invention: by traditional attacker's formula release mechanism, change draw-ring type release mechanism into, motion lever principle, the upset achieving back seat backrest unlocks, reduce manufacturing cost, operate very laborsaving, the releasing force of attacker's formula release mechanism is about 80N, and the releasing force of draw-ring type release mechanism is about 30N; Continue after unblock to pull draw ring, then back of seat can be driven to overturn, do not need to vacate other hand and coordinate, one hand can complete; When back of seat is down flat forward, people stands in boot, and to pull draw ring ratio to pull attacker convenient; There is not the potential safety hazard of tong simultaneously yet.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 is the partial enlarged drawing of Fig. 1.
Fig. 3 is the structural representation of existing back seat backrest upset release mechanism.
Detailed description of the invention
Below by embodiment also by reference to the accompanying drawings, the invention will be further described:
Shown in composition graphs 1, Fig. 2, a kind of back seat backrest upset release mechanism, forms primarily of a backrest unblock stay cord left side 1, the backrest unblock stay cord right side 2, draw ring 3, draw ring support 4, unblock drawstring 5, "T"-shaped release lever 6, handle mounting bracket 7, handle returning pull-spring 8.
Draw ring support 4 is fixedly mounted on the upper lateral tube of backrest 9, draw ring support 4 preferably Plastic Parts, and center ofthe is arranged, and draw ring support 4 is provided with drawstring via hole and passes through for unlocking drawstring 5.The upper end unlocking drawstring 5 is connected with draw ring 3 through draw ring support 4, and it is hinged that the lower end of unblock drawstring 5 and the afterbody of "T"-shaped release lever 6 pass through the second hinge-point B.
The middle position of "T"-shaped release lever 6 head is hinged on handle mounting bracket 7 by the first hinge-point A, and during by External Force Acting, "T"-shaped release lever 6 rotates around the first hinge-point A.Handle mounting bracket 7 is fixedly mounted in the skeleton of backrest 9, and backrest plane can not be given prominence in front and back, can not affect the overall dimensions of backrest.
The upper end on a backrest unblock stay cord left side 1 is connected to one end of "T"-shaped release lever 6 head, the upper end on the backrest unblock stay cord right side 2 is connected to the other end of "T"-shaped release lever 6 head, and the backrest unblock upper end on a stay cord left side 1 and the distance of the first hinge-point A equal backrest and unlock the upper end on the stay cord right side 2 and the distance of the first hinge-point A.Backrest unlocks the left and right lower end of 1,2 of stay cord and is connected with the floor latch of backrest 9 respective side respectively, realizes left and right sides synchronizing unlocking.
When pulling draw ring 3, draw ring 3 pulls "T"-shaped release lever 6 to rotate around the first hinge-point A by unlocking drawstring 5, "T"-shaped release lever 6 pulls backrest to unlock stay cord left and right 1,2 and rotates towards the direction away from each self-corresponding floor latch respectively, after unclamping draw ring 3, "T"-shaped release lever 6 self-return under the effect of handle returning pull-spring 8.
