Description

Technical Field

[0001] The utility model relates to the technical field of automobile seats, in particular to a novel seat connecting rod shielding structure. Background Art

[0002] There is a linkage flat structure between the seat cushion and the backrest of the rear seat of the car, which is widely used in the current passenger car market. This structure connects the seat cushion and the backrest frame through a connecting rod, and the connecting rod usually needs to be shielded. The current mainstream is to shield the metal connecting rod by attaching plastic parts. There are three disadvantages of the plastic parts shielding method: 1. The plastic parts need to be developed and designed, which increases the cost of a seat. 2. There is a problem of appearance matching between the plastic parts and the main appearance of the seat. The style is difficult to integrate into the leather or imitation leather appearance of the car seat, which destroys the overall shape and causes a bad effect on the appearance of the seat. 3. Plastic parts are hard parts, and there are problems such as the need to reserve gaps between relatively moving parts, easy holes between plastic parts, and easy to see through. Other compensation measures are required for automotive parts, which increases the cost of the whole vehicle. Utility Model Content

[0003] In view of the problems existing in the above-mentioned prior art, the utility model aims to provide a novel seat connecting rod shielding structure, which shields the seat connecting rod by means of a zipper combined with a cover, so that the overall appearance of the seat remains uniform and is conducive to cost saving.

[0004] In order to achieve the above-mentioned purpose, the utility model proposes a novel seat link shielding structure, including a seat four-link frame, a front floor bracket and a rear floor bracket fixed on the vehicle body floor, the seat four-link frame is hinged on the front floor bracket and the rear floor bracket, the seat four-link frame includes a backrest frame, a cushion frame, a front link and a seat connecting rod, the backrest frame is flipped forward and laid flat from the use position, the seat four-link frame is linked, the backrest frame is covered with backrest foam, the backrest foam upper edge is seated An avoidance groove is provided in the movement direction of the connecting rod, and a backrest back cover is covered on the backrest foam. A zipper is provided on the backrest back cover at the position corresponding to the avoidance groove. The pull head of the zipper faces inward relative to the backrest back cover, and the pull head is connected to the rear floor bracket. When the backrest frame flips forward, the pull head is restricted by the rear floor bracket and moves up relative to the zipper, thereby pulling the zipper to open the avoidance groove and realize the function of avoiding the sitting connecting rod. When the backrest frame returns to its position backward, the pull head moves down relative to the zipper, thereby closing the zipper and realizing the closing of the avoidance groove.

[0005] In the above scheme: the pull head is connected to the rear floor bracket through a spring to alleviate the impact load during the zipper closing process.

[0006] In the above scheme: a slider fixing hole is arranged at the upper end of the rear floor bracket, one end of the spring is hooked on the slider fixing hole and the other end is hooked on the slider, the installation structure is simple and the assembly is convenient.

[0007] In the above scheme: the upper end of the front connecting rod is hinged to the front end of the seat frame, the lower end of the front connecting rod is hinged to the front floor bracket, the bottom end of the backrest frame is hinged to the rear floor bracket, the front end of the seat support connecting rod is hinged to the rear end of the seat frame, and the rear end of the seat support connecting rod is hinged to the lower end of the backrest frame, thereby forming a linkage mechanism. When the backrest frame flips forward, the front connecting rod flips forward around the front floor bracket, driving the seat frame to move forward, and at the same time, the seat support connecting rod moves forward relative to the backrest frame.

[0008] In the above solution: the seat support connecting rod is in an "L" shape, and its horizontal section is located in front of the vertical section. This shape design makes it easy to hide the seat support connecting rod inside the seat.

[0009] The beneficial effects of the utility model are:

[0010] Abandoning the traditional plastic parts used to cover the seat connecting rod, an avoidance groove is opened on the backrest foam along the movement direction of the seat connecting rod, and the seat connecting rod is covered by a zipper combined with a face cover, that is, the back cover is closed with a zipper to ensure that there are no gaps in the avoidance groove when the backrest frame is in use position, and at the same time to ensure that the movement of the seat connecting rod is not obstructed during the folding of the backrest. The overall structure is simple and the cost is low, and the pull head faces inward relative to the back cover and cannot be directly seen from the outside of the seat, which is conducive to maintaining a unified overall appearance of the seat.

[0017] like Figure 1—6 shows a novel seat link shielding structure, which is mainly composed of a seat four-link frame, a front floor bracket 1 and a rear floor bracket 2 fixed on the vehicle body floor.

[0018] The four-link seat frame is hinged on the front floor support 1 and the rear floor support 2, and the four-link seat frame includes a backrest frame 3, a cushion frame 4, a front link 5 and a seat connection rod 6. When the backrest frame 3 is flipped forward and laid flat from the use position, the four-link seat frame is linked. The backrest frame 3 is covered with a backrest foam, and an escape groove 7 is provided on the backrest foam along the movement direction of the seat connection rod 6. The backrest foam is covered with a backrest back cover, and a zipper 8 is provided on the backrest back cover at the position corresponding to the escape groove 7. The pull head 81 of the zipper 8 faces inward relative to the backrest back cover, and the pull head 81 is connected to the rear floor support 2.

[0019] When the backrest frame 3 flips forward, the slider 81 is restricted by the rear floor bracket 2 and moves upward relative to the zipper 8, thereby pulling the zipper 8 to open the avoidance groove 7 and realize the function of avoiding the seat connecting rod 6; when the backrest frame 3 returns to its original position backward, the slider 81 moves downward relative to the zipper 8, thereby closing the zipper 8 and realizing the closing of the avoidance groove 7.

[0020] Preferably, the slider 81 is connected to the rear floor support 2 via a spring to alleviate the impact load during the closing process of the zipper 8.

[0021] Preferably, a slider fixing hole 21 is provided at the upper end of the rear floor bracket 2, one end of the spring is hooked on the slider fixing hole 21, and the other end is hooked on the slider 81, so that the installation structure is simple and easy to assemble.

[0022] Preferably, the upper end of the front connecting rod 5 is hinged to the front end of the seat cushion frame 4, the lower end of the front connecting rod 5 is hinged to the front floor bracket 1, the bottom end of the backrest frame 3 is hinged to the rear floor bracket 2, the front end of the seat support connecting rod 6 is hinged to the rear end of the seat cushion frame 4, and the rear end of the seat support connecting rod 6 is hinged to the lower end of the backrest frame 3, thereby forming a linkage mechanism. When the backrest frame 3 flips forward, the front connecting rod 5 flips forward around the front floor bracket 1, driving the seat cushion frame 4 to move forward, and at the same time, the seat support connecting rod 6 moves forward relative to the backrest frame 3.

[0023] Preferably, the seat support connecting rod 6 is in an "L" shape, with its transverse section located in front of the vertical section. This shape design facilitates hiding the seat support connecting rod 6 inside the seat.

[0024] Preferably, the zipper 8 is connected to the backrest cover by sewing, which has low processing cost and is easy and quick to operate.
