Problems solved by technology

In order to unlock the backrest lock and the pin lock at the same time, a splitter structure is usually used, that is, the splitter has a bus and two branch lines connected to the pin lock and the backrest lock respectively, and the operation of the bus through an unlocking and starting device, The two branch lines are used to pull and unlock the pin lock and the backrest lock respectively, realizing one-time unlocking of the pin lock and the backrest lock. However, the structure of the line divider is added to the structure, which will inevitably increase the manufacturing cost. In addition, due to the pin The unlocking of the lock and the backrest lock is different, which leads to the fact that when one of them is unlocked, the other may not be unlocked, that is, the unlocking operations of the two locks are not synchronized. Therefore, the operator mistakenly believes that the backrest has been unlocked, thus stopping to continue to pull to unlock Activate the device so that the backrest cannot be unlocked smoothly

Embodiment 1

[0020] Depend on figure 1 , figure 2 As shown, the vehicle seat back locking system involved in this embodiment has a backrest lock and a pin lock 2 that is unlocked by being pulled by the force end of the second pull wire 1, wherein the pin lock 2 adopts an existing structure, such as Figure 4 As shown, the pin lock 2 generally includes a housing 21, a lock pin 22 slidably arranged in the housing 21, a sleeve spring 23 sleeved on the lock pin 22, and the tail end of the lock pin 22 is connected with a second pull wire 1, through The pulling of the lock pin 22 by the second pull wire 1 makes the lock pin 22 move in the casing 21 to realize that the head end of the pin lock 2 is separated from the lock hole and unlocked.

[0021] Depend on image 3 As shown, the backrest lock 12 has an upper lock plate 4 and a lower lock plate 5, and the upper lock plate 4 and the lower lock plate 5 are respectively rotated by the first rotating shaft 45 and the second rotating shaft 52 and...

Embodiment 2

[0028] This embodiment relates to a vehicle seat, such as Figure 5 As shown, it includes a base 9, a backrest 10 that is rotationally connected with the base 9 through a rotating shaft, and a vehicle seat back locking system. The vehicle seat back locking system has the structure described in Embodiment 1, and the backrest lock 12 is installed on the Above the backrest 10 on one side of the car door, the lock pin 2 and the backrest lock 12 are arranged diagonally relative to the backrest. Specifically, the pin lock 2 is arranged below the rotation axis of the backrest 10 away from the car door.

Abstract

The invention relates to a device for unlocking a vehicle seat backrest, in particular to a vehicle seat backrest locking system. The vehicle seat backrest locking system is provided with a backrest lock and a pin lock (2) unlocked under the traction action of the force application end of a second pulling wire (1), wherein the backrest lock is provided with an upper lock plate (4), a lower lock plate (5) driving the upper lock plate (4) in a rotating manner, and a first pulling wire (6) connected with the lower lock plate (5); the force application end of the second pulling wire (1) is fixedly connected onto the lower lock plate (5); and when the first pulling wire (6) is dragged to rotate the lower lock plate (5), the lower lock plate (5) enables the second pulling wire (1) to have a displacement for unlocking the pin lock (2) due to rotation. Meanwhile, the invention provides a vehicle seat with the vehicle seat backrest locking system. Due to the adoption of the technical scheme, the manufacturing cost of a product can be effectively saved; and in addition, the pin lock and the backrest lock can be synchronously unlocked, so that incomplete unlocking is avoided.

Description

technical field [0001] The invention relates to a device for unlocking a vehicle seat back, in particular to a vehicle seat back locking system. At the same time, the invention also provides a vehicle seat with the vehicle seat back locking system. Background technique [0002] Most of the existing vehicle seats are equipped with a vehicle seat back locking system. One of the main functions of this system is to relieve the deformation of the middle part of the rear seat back when the vehicle is subjected to a severe collision or impact. and increase the anti-deformation strength. In the prior art, the combination of backrest lock and pin lock is generally adopted, wherein the backrest lock mostly adopts the form of combining the upper lock body and the lower lock body (as disclosed in the Chinese invention patent application CN102224035A for the locking of vehicle seats unit), the upper lock body and the lower lock body are rotatably set on the bottom plate fixed to the se...
