Detailed Description

The utility model will be further explained with reference to the drawings.

In the present embodiment, as shown in fig. 1 to 7, a seat cushion assembly for a seat includes a cushion member 4, a cushion frame base 1, and a turnover mechanism; the turnover mechanism comprises two connecting rod assemblies which are arranged in bilateral symmetry. The connecting rod assembly comprises a first rotating support 7 and a second rotating support 2, one end of the first rotating support 7 is hinged to the front end portion of the seat cushion assembly 4, the other end of the first rotating support 7 is hinged to one end of the second rotating support 2, and the other end of the second rotating support 2 is hinged to the front end portion of the seat cushion framework base 1.

As shown in fig. 3, in this embodiment, the turnover mechanism further includes a connecting rod 17, and left and right ends of the connecting rod 17 are respectively fixedly connected to inner sides of the two second rotating brackets 2.

As shown in fig. 3 and 4, the present embodiment further includes a latch hook 12, a latch lever 11 and a pull tape 5; the lock hook 12 is connected to the seat cushion assembly 4 through a rotating shaft, the upper end of the lock hook 12 is connected with one end of the pull belt 5, and the lower end of the lock hook 12 is provided with a hooking part. The lock rod 11 is fixedly arranged on the connecting rod 17, and when the seat cushion assembly 4 is in a horizontal state, the hooking part of the lock hook 12 can be hooked on the lock rod 11.

As shown in fig. 4, in the present embodiment, a return spring 18 is sleeved on the rotating shaft, one end of the return spring 18 acts on the lock hook 12, and the other end of the return spring 18 is fixed on the seat cushion assembly 4. The end part of the second rotating bracket 2 connected with the first rotating bracket 7 is provided with a rotating bracket protecting cover 3.

As shown in fig. 3, 5 and 6, in the present embodiment, an automotive rear seat includes a backrest frame assembly 14 and a seat cushion assembly, wherein the seat cushion employs a seat cushion assembly according to the present invention; the lower end of the backrest frame assembly 14 is connected with the rear end of the seat cushion frame base 1 of the seat cushion assembly through an angle adjuster.

As shown in fig. 7, in the present embodiment, a front cushion pad 13 is provided on the front end portion of the seat frame base 1. The rear end part of the seat cushion framework base 1 is provided with a rear shock pad 19.

In this embodiment, an automobile adopts the automobile rear seat as described in this embodiment.

The seat mounting bolts are respectively fixed on the floor of the vehicle body through the front mounting foot plate 16, and the seat mounting bolts are fixed on the floor of the vehicle body through the rear mounting foot plate 15.

The working principle of the embodiment is as follows:

(1) the folding process:

pulling the pull belt 5, the lock hook 12 rotates around the rotating shaft, and the lock hook 12 is separated from the lock rod 11 to realize unlocking. Pulling on the pull strap 5 then causes the seating pad assembly 4 to pivot about the third center of rotation 9, thereby folding the seating pad assembly 4 from the horizontal orientation to the vertical orientation. The position of the seat cushion assembly 4 in the front-back direction is adjusted through the second rotation center 8, and more space is reserved for folding the backrest. The angle of the cushion component is adjusted through the first rotating center 6, so that the cushion component can be better attached to the back of the front-row backrest, and meanwhile, the backrest framework assembly 14 can be smoothly laid down in a limited space under the condition that the back-row backrest is turned over and the headrest is not detached, so that the backrest framework assembly 14 and the cushion component 4 are ensured not to interfere in the laying process. And unlocking the backrest through the angle adjuster, wherein after the backrest is unlocked, the backrest framework assembly 14 can rotate around the fourth rotation center 10 to perform the falling operation. Because the seat cushion member 4 has been folded forward and moved, there is enough space for the back frame assembly 14 to lie down, so that the back frame assembly 14 lies directly on the floor. After the backrest frame assembly 14 is laid down, the backrest foam and the surface cover may contact the first rotating bracket 7 and the second rotating bracket 2, and the surface cover may be protected from being cut by the rotating bracket cover 3 in this embodiment. The back of the backrest has enough height space with the car roof, and the back of the backrest in the back row and the trunk can be placed at the level of 0-3 degrees.

(2) Folding process:

the backrest frame assembly 14 is unlocked by the recliner and the fourth center of rotation 10 positions the backrest frame assembly 14 in the use position. The pulling strip 5 is pulled by the external force to make the seat cushion assembly 4 pass through the first rotation center 6, the second rotation center 8 and the third rotation center 9 to make the seat cushion assembly 4 be in the using position. In order to prevent the seat cushion assembly 4 from colliding and abnormal sound with the seat cushion frame base 1 in the turnover process, the front shock absorption pad 13 and the rear shock absorption pad 19 are installed on the seat cushion frame base 1, and the abnormal sound of the seat cushion in the use position is also avoided.
