Description

Technical Field

[0001] This utility model belongs to the technical field of automotive seat leg support accessories, and relates to a seat cover tightening structure that is matched with automotive seat leg support. Background Technology

[0002] Leg rests are typically found on the seats of relatively high-end vehicles, especially luxury sedans, MPVs, and SUVs. The purpose of a leg rest is to increase the area of ​​support for the occupant's legs, thereby providing the desired comfort.

[0003] During the adjustment process of the leg rest, that is, when adjusting forward or backward, the car seat cover will adapt. Therefore, in order to meet the adaptability of the seat cover, a seat cover tightening device, also known as a "seat cover pre-tightening device", is usually matched with the car seat leg rest. However, the existing tightening devices have relatively simple specifications. When installing different models of seats, it is necessary to modify and adjust the dimensions of multiple components within the device, which reduces the overall adaptability of the tightening structure. Therefore, there is a need for a seat cover tightening structure that can adapt to different models of seats by adjusting the size of a single component to solve the above problems.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] The following is in conjunction with the appendix Figures 1 to 3The specific embodiments of this utility model will be described in further detail.

[0022] Depend on Figures 1 to 3 As shown, this utility model includes two fixing plates 1 that are fixedly connected to the seat. In order to facilitate the tightening of the seat cover, a rotating hole 2 is provided in the middle of each fixing plate 1. A rotating shaft 3 is provided inside each rotating hole 2. A vertical rod 4 is fixedly connected to the outside of each rotating shaft 3. A tightening rod 5 for tightening the seat cover is connected between the two vertical rods 4. A bushing 6 is fixedly connected to the outside of each rotating shaft 3. A torsion spring 7 is fitted on the outside of each bushing 6. The end of each torsion spring 7 away from the bushing 6 abuts against the corresponding vertical rod 4.

[0023] In use, the fixing plate 1 is used to fix the entire device. After the fixing plate 1 is fixedly connected to the lower side of the car seat (or the back side of the leg rest, depending on the actual situation, there is no restriction here), the tightening rod 5 can be connected to the seat cover. When the leg rest of the car seat moves (rotates or extends relative to the seat), the seat cover at the leg rest will slide relative to the leg rest of the seat. Therefore, the seat cover will pull the tightening rod 5 to move, thereby causing the torsion spring 7 to store force. When the leg rest moves in the opposite direction, under the action of the torsion spring 7, the tightening rod 5 can always have the force to tighten the seat cover, reducing the probability of seat cover wrinkles.

[0024] Furthermore, by Figures 1 to 3 As shown, in order to limit the tightening position, a first bending plate 8 is fixedly connected to the lower side of the fixed plate 1. The side of each first bending plate 8 near the vertical rod 4 abuts against the vertical rod 4. It should be noted that a buffer block is fixedly connected to the side of the first bending plate 8 near the vertical rod 4, which can reduce the noise when the first bending plate 8 contacts the vertical rod 4.

[0025] In use, by setting the first bending plate 8, a preload can be applied to the vertical rod 4 through the torsion spring 7, thereby ensuring that the tightening rod 5 always tightens the seat cover. The first bending plate 8 is used to limit the movement limit position of the vertical rod 4.

[0026] Furthermore, by Figures 1 to 3 As shown, in order to facilitate the staff to fix the fixing plate 1, a horizontal plate 9 is fixedly connected to the upper side of the fixing plate 1. The horizontal plate 9 has multiple fixing holes and a clearance groove 10 is provided in the middle of the horizontal plate 9.

[0027] In use, the horizontal plate 9 can be fixed to a suitable position at the bottom of the seat or the back of the leg rest by using bolts and nuts through the fixing holes on the horizontal plate 9. This completes the installation of the device. During installation, the positioning groove 10 makes it easier to position the horizontal plate 9 and the fixing plate 1, reducing installation errors and thus reducing the scrap rate.

[0028] Furthermore, by Figures 1 to 3 As shown, in order to increase the service life of the device, a second bending plate 11 is fixedly connected to the rear side of the horizontal plate 9, and a first connecting hole 12 is provided in the middle of the second bending plate 11.

[0029] Furthermore, by Figures 1 to 3 As shown, in order to be compatible with different seats, the torsion spring 7 has a first bending part 13 on the side close to the vertical rod 4 and a second bending part 14 on the side away from the vertical rod 4. The first bending part 13 is fitted on the outside of the vertical rod 4, and the second bending plate 11 passes through the first connecting hole 12 and is engaged with the second bending plate 11.

[0030] In use, by setting the first connecting hole 12, the second bending part 14 can pass through the first connecting hole 12 and engage with the second bending plate 11, which can effectively limit the fixed end of the torsion spring 7. By engaging the first bending part 13 with the vertical rod 4, the length of the vertical rod 4 can be adjusted according to the different seat models during actual use, thereby enabling the device to be adapted to different seat models and increasing the adaptability of the torsion spring 7 installation structure.

[0031] Furthermore, by Figures 1 to 3 As shown, in order to reduce the friction between the rotating rod and the fixed plate 1, a bushing 15 is provided inside the rotating hole 2;

[0032] In use, bushing 15 can reduce the friction between the rotating rod and the fixed plate 1, and at the same time reduce the noise generated by their collision.

[0033] Furthermore, by Figures 1 to 3 As shown, in order to reduce the probability of the bushing 6 falling off, a slot 16 is provided at the end of each rotating shaft 3, and a rubber plate 17 is engaged inside the slot 16.

[0034] When in use, the rubber clamp 17 can be engaged with the groove 16, which can limit the position of the bushing 6 and reduce the probability of the bushing 6 coming off the outside of the rotating rod.

[0035] It should be noted that bushing 15, bushing 6, and rubber clamp 17 are made of one of the following: natural rubber, styrene-butadiene rubber, butadiene rubber, chloroprene rubber, or nitrile rubber.

[0036] When using this utility model, the fixing plate 1 is first used to fix the entire device. After the fixing plate 1 is fixedly connected to the lower side of the car seat (or the back side of the leg rest), the tightening rod 5 can be connected to the seat cover. When the leg rest of the car seat moves, the seat cover at the leg rest will slide relative to the leg rest of the seat. Therefore, the seat cover will pull the tightening rod 5 to move, thereby causing the torsion spring 7 to store force. When the leg rest moves in the opposite direction, under the action of the torsion spring 7, the tightening rod 5 can always have the force to tighten the seat cover, reducing the probability of the seat cover wrinkling.

[0037] This utility model has a novel structure, ingenious design, and simple and convenient operation. Through this design, it effectively achieves the purpose of tightening the seat cover, realizes the function of limiting the tightening position, facilitates the staff to fix the fixing plate 1, increases the service life of the device, reduces the friction between the rotating rod and the fixing plate 1, and reduces the probability of the bushing 6 falling off.

[0038] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
