Description
Technical field
The invention belongs to automotive seating art field, particularly relate to a kind of back seat backrest installation structure.
Background technology
Passenger car is to increase luggage boot space, and usual back seat backrest is turning structure, that is, in use,
The folding of backrest can be realized by switching mechanism and seat lock；And the back seat of commercial car is typically secured to back wall horizontal stroke
Liang Shang, back space narrow and small it is not necessary to realize turn over function, cost-saved, and ensure the reliability of product.
The back seat fixed mechanism of existing passenger car is turning structure, has following two structures at present：
The first structure as depicted in figs. 1 and 2, is backrest steel wire interface arrangment, and vehicle body sheet metal 1 welds the hook-shaped folding of V-type
Steel wire 4 clamping in comer pieces 2, with the seat reclining back of the body 3, Y-direction degree of freedom is unrestricted, can produce Y-direction relative motion, and backrest steel wire
On covering material easy to wear, lead to steel wire and V-type hook-shaped bending part metal bump, produce the defects such as abnormal sound.
Second structure as shown in Figure 3 and Figure 4, is backrest lock construction, and seat backrest latch 5 is installed on vehicle body by bolt
On panel beating, backrest foaming built-in backrest lock 6, backrest lock is realized by the construction of switch of backrest shoulder
Closure, complex structure, high cost, maintenance convenience is poor.
The shortcoming of existing above two passenger car back seat fixed mechanism is：
Because the hook-shaped bending part of V-type is unrestricted with the steel wire Y-direction degree of freedom of seat reclining back during traveling, Y-direction is produced
Raw relative motion, covering material abrasion on backrest steel wire, lead to steel wire and V-type hook-shaped bending part metal bump, back seat leans on
The back of the body rocks, and produces abnormal sound, the in-car noise of impact.
With the turning complex structure of backrest lock, relatively costly, and latch hook position is by latching the rubber in plastic and lock body
, gap after plastic part abrasion in pad locking, or not resilience after rubber blanket compression, between leading to occur between lock and lock body
Gap, equally exists the defects such as abnormal sound.
Content of the invention
It is an object of the invention to provide a kind of back seat backrest installation structure technical scheme, by the technical program, energy
Enough backrest X that effectively limits are to the degree of freedom with Y-direction, it is to avoid seat produces and rocks with defects such as abnormal sounds it is ensured that seat
Reliability, lifting driver's cabin comfortableness.
The present invention is achieved by the following technical solutions：
