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 backrest unlock component 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 unlock component 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 draw-ring type backrest unlock component, 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 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,
Described handle mounting bracket is welded by the support tube of " 7 " font and stamping steel plate, one end of described support tube is welded on the central post of backrest frames, the other end is welded on the lower transverse tubule of backrest frames, thus surrounds quadrangle with subordinate's corner in backrest frames; Described stamping steel plate is welded on support tube, stamping steel plate is provided with for backrest unlock pass through on a stay cord left side the first guiding journal stirrup, to unlock for backrest pass through on the stay cord right side the second guiding journal stirrup, for handle returning pull-spring one end hooking installation journal stirrup, be positioned at lower limit journal stirrup below "T"-shaped release lever, described first guiding journal stirrup and lower limit journal stirrup are to the rotary spacing of "T"-shaped release lever.
Preferred as such scheme, described "T"-shaped release lever is formed by steel plate punched, have reinforced rib in "T"-shaped release lever upper punch, described reinforced rib extends to the second hinge-point from the first hinge-point, increases the intensity of the main force part of "T"-shaped release lever.
Beneficial effect of the present invention: by traditional attacker's formula unlock component, change draw-ring type unlock component into, motion lever principle, the upset achieving back seat backrest unlocks, operate very laborsaving, the releasing force of attacker's formula unlock component is about 80N, and the releasing force of draw-ring type unlock component 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; And optimize the structure and layout of handle mounting bracket, reduce manufacturing cost.
