AI Technical Summary
The existing car seat slides cannot automatically move forward after the middle row seat is unlocked, and the angle adjuster only has the angle adjustment function but does not have the linkage function, so the slide rail cannot be unlocked.
A car seat slide rail that is unlocked in a linkage with the backrest is designed, including a left slide rail group, a right slide rail group and a handle device. The automatic forward movement and angle adjustment of the seat are achieved through the combination of the linkage device (pulling spring and pulling wire) and the locking mechanism (left locking mechanism and right locking mechanism).
Through the handle unlocking and rotating the adjuster, the front and rear position adjustment of the seat and the backrest angle adjustment are realized. At the same time, under the action of the pulling spring, the seat can automatically move forward, solving the problem that the seat cannot automatically move forward in the prior art.

[0022] The left slide rail assembly 1 in this embodiment includes a left upper slide rail 11 and a left lower slide rail 12 . The left upper slide rail 11 is slidably mounted on the left lower slide rail 12 and fixed by a left locking mechanism. The left lower slide rail 12 is mounted on the vehicle floor by a left mounting foot 13 .
[0023] The right slide rail assembly 2 in this embodiment includes a right upper slide rail 21 and a right lower slide rail 22 . The right upper slide rail 21 is slidably mounted on the right lower slide rail 22 and fixed by a right locking mechanism. The right lower slide rail 22 is mounted on the vehicle floor by a right mounting foot 23 .
[0024] The handle device 3 in this embodiment includes a left locking mechanism, a right locking mechanism and a handle 37. Both ends of the handle 37 cooperate with the left locking mechanism and the right locking mechanism respectively.
[0025] The left locking mechanism in this embodiment includes a left fixed bracket 31, a left locking pin 32 and a left pressure plate 33. The left fixed bracket 31 and the left locking pin 32 are both installed on the left upper slide rail 11, and the left upper slide rail 11 and the left lower slide rail 12 are fixed by the left locking pin 32, and the left locking pin 32 cooperates with the left pressure plate 33.
[0026] The right locking mechanism in this embodiment includes a right fixed bracket 34, a right locking pin 35 and a right pressure plate 36. The right fixed bracket 34 and the right locking pin 35 are both installed on the right upper slide rail 21, and the right upper slide rail 21 and the right lower slide rail 22 are fixed by the right locking pin 35, and the right locking pin 35 cooperates with the right pressure plate 36.
[0027] The left pressing plate 33 and the right pressing plate 36 in this embodiment are respectively fixed to the two ends of the handle 37 , and the two ends of the handle 37 are rotatably connected to the left fixing bracket 31 and the right fixing bracket 34 .
[0028] The linkage device 4 in this embodiment includes a tension spring 41, a tension spring bracket 42, a wire bracket 43 and a tension wire. The tension spring bracket 42 is installed on the left mounting foot 13 or the right mounting foot 23, one end of the tension spring 41 is connected to the tension spring bracket 42, and the other end of the tension spring 41 is connected to the seat frame. The wire bracket 43 is installed on the handle 37, one end of the tension wire is connected to the wire bracket 43, and the other end of the tension wire is connected to the angle adjuster.
[0029] Specifically, the car seat slide rail that is unlocked in conjunction with the backrest can be installed on the middle row of seats in a commercial vehicle. There are two unlocking methods when in use. The first unlocking method: when there is someone in the middle row of seats, the left locking mechanism and the right locking mechanism can be unlocked by pulling the handle 37 upwards. When the force of the person's legs supporting the vehicle floor when sitting on the seat is greater than the tension of the tension spring 41, the seat can be moved backward. When the force of the person's legs supporting the vehicle floor when sitting on the seat is less than the tension of the tension spring 41, the seat can automatically move forward under the action of the tension of the tension spring 41.
[0030] The second unlocking method: when there is no one in the middle row of seats, a person sits in the back seat, or a person stands outside the car and turns the angle adjuster to tilt the middle row of seats forward. At the same time, when turning the angle adjuster, the handle 37 can be pulled upward by the pull wire to unlock the left locking mechanism and the right locking mechanism. Since there is no one sitting in the middle row of seats, the seat can be moved forward under the action of the tension spring 41.
[0031] It should be noted that the seat frame is a part of the seat, and the bottom of the seat is the seat frame. "Unlocking in conjunction with the backrest" means that the angle of the backrest can be adjusted by rotating the angle adjuster. At the same time, the locking mechanism can be unlocked, and the seat can be moved forward under the action of the tension spring 41.
[0032] In addition, it should be noted that the shapes and names of the parts and components of the specific embodiments described in this specification may be different, and the above content described in this specification is only an example of the structure of the utility model. All equivalent changes or simple changes made based on the structure, features and principles described in the patent concept of the utility model are included in the protection scope of the utility model patent. Technicians in the technical field of the utility model can make various modifications or supplements to the specific embodiments described or replace them in a similar manner, as long as they do not deviate from the structure of the utility model or exceed the scope defined by the claims, they should all fall within the protection scope of the utility model.
