Problems solved by technology

Double slide rail structure, when unlocking, both sides need to be unlocked at the same time, often there are asynchronous problems, the installation requires high precision, high cost, and heavy weight; and the floor needs to provide enough installation space and reserved installation holes; and in front of and behind the seat It is inconvenient to set the sliding rail adjustment method. When the rear passenger space is insufficient, passengers cannot adjust the front seat position in the rear row to increase the rear space

Embodiment 1

[0049] Such as Figure 1-2 As shown, the seat includes a seat cushion 20 , a seat frame 30 and a seat slide rail adjustment device 10 , and the seat slide rail adjustment device 10 is installed on the center line of the bottom of the seat frame 30 along the front-rear direction of the vehicle body.

[0050] Wherein, the seat slide rail adjustment device 10 includes a slide rail 1 and an unlocking unit 2, the slide rail 1 includes an outer rail 11 and an inner rail 12, the inner rail 12 slides in the outer rail 11, and the unlocking unit 2 is installed on the inner rail 12 for There is only one slide rail 1 for locking or unlocking with the outer rail 11.

[0051] In this embodiment, since there is only one slide rail 1, the installation accuracy is low, the cost is low, the weight is light, and the front and rear positions of the seat are easy to adjust.

[0052] Further, as figure 2 As shown, the slide rail 1 further includes an inner rail connecting plate 13 , the inner r...

Embodiment 2

[0056] Such as Figure 3-9 As shown, it is a structural schematic diagram of the seat slide rail adjusting device in the second embodiment.

[0057] Among them, such as Figure 3-4 As shown, the unlocking unit 2 includes an unlocking handle 21, an unlocking post 22 and a claw 23. The unlocking handle 21 rotates on a vertical plane, drives the unlocking post 22 to rotate on a horizontal plane, and the unlocking post 22 drives the pawl 23 to rotate on a horizontal plane and the outer rail Unlocked between 11.

[0058]Since the unlocking handle 21 rotates on the vertical plane, it drives the unlocking column 22 to rotate on the horizontal plane, and the unlocking column 22 drives the claw 23 to unlock between the horizontal plane rotation and the outer rail 11. The stroke of the claw 23 is small, and the claw can be reduced 23 size, reducing the space occupied by the entire seat slide rail adjustment device.

[0059] Further, as image 3 As shown, the unlocking handle 21 incl...

Abstract

A seat rail adjustment device includes a slide rail and an unlocking unit. The slide rail includes an outer rail and an inner rail, the inner rail slides in the outer rail, the unlocking unit is installed on the inner rail for locking or unlocking with the outer rail, The unlocking unit comprises an unlocking handle, an unlocking post and a jaw. The unlocking handle rotates on a vertical plane todrive the unlocking post to rotate on a horizontal plane, and the unlocking post drives the jaw to unlock between the horizontal plane rotation and the outer rail. The invention also discloses a seat.As there is only one slide rail in that invention, the installation precision requirement is low, the cost is low, the weight is light, and the front and rear position of the seat is easy to adjust.The unlocking handle rotates on the vertical plane to drive the unlocking column to rotate on the horizontal plane, and the unlocking column drives the jaws to unlock between the horizontal plane rotation and the outer rail, so that the travel of the jaws is small, the size of the jaws can be reduced, and the space occupied by the entire seat slide rail adjusting device can be reduced. The unlocking handle rotates on the vertical plane to drive the unlocking column to rotate on the horizontal plane.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a seat slide rail adjustment device and a seat. Background technique [0002] At present, most of the manual style seats and small sub-seats with sliding armrests on the market have a double slide rail structure. Double slide rail structure, when unlocking, both sides need to be unlocked at the same time, there are often asynchronous problems, the installation requires high precision, high cost, and heavy weight; and the floor needs to provide enough installation space and reserved installation holes; and in front of and behind the seat It is inconvenient to set the sliding rail adjustment method. When the rear passenger space is insufficient, the passenger cannot adjust the front seat position in the rear row to increase the rear space. [0003] Therefore, it is necessary to design a seat slide rail adjustment device and a seat that require low installation accuracy, low co...
