Description

Technical fields:

[0001] This utility model belongs to the field of automotive technology, and specifically refers to a B-pillar seat belt sliding plate moving component. Background technology:

[0002] As automobiles become increasingly important tools in human life, the height of seat belts often needs to be adjusted to improve comfort due to the different physiques of drivers. Therefore, B-pillar trim panels on the market are often equipped with adjustable sliding plates that can slide up and down, as well as seat belt adjustment mechanisms that can lock the position of the adjustable plate and are connected to the seat belt, such as the B-pillar seat belt height adjustment structure disclosed in the existing Chinese invention patent (authorization announcement number CN110126778B). Currently, the adjustable plate that moves up and down within the B-pillar trim panel generally uses a structure of metal guide rails and rollers, which has the following drawbacks: First, the metal guide rail and rollers are rigidly connected, which is prone to wear, and the increased assembly clearance can lead to vibration and continuous loosening and abnormal noise during vehicle operation; Second, the metal guide rail is prone to corrosion, affecting the smoothness of sliding. Summary of the Invention:

[0003] The purpose of this utility model is to provide a B-pillar seat belt sliding plate moving component, which, through the dynamic friction cooperation between the damping rubber strip and the matching sliding groove, can not only compensate for wear in a timely manner to ensure that the seat belt sliding plate and the B-pillar trim panel are stably matched and do not wobble, but also provide damping feedback to the driver and passengers when the seat belt height is adjusted.

[0004] This utility model is implemented as follows:

[0005] A B-pillar seatbelt sliding plate moving assembly includes a B-pillar trim panel body and a seatbelt sliding plate that slides vertically and horizontally on the B-pillar trim panel body. The left and right sides of the inner wall of the B-pillar trim panel body are provided with mating grooves in the vertical direction. The two sides of the seatbelt sliding plate are respectively located in the corresponding mating grooves. The side of the seatbelt sliding plate is provided with a damping rubber strip in the inward and outward direction. The damping rubber strip abuts against and dynamically rubs against the inner groove wall of the mating groove.

[0006] In the aforementioned B-pillar seatbelt sliding plate moving assembly, both the B-pillar trim panel body and the seatbelt sliding plate have U-shaped cross-sections. The inner walls of both shoulder walls of the B-pillar trim panel body are provided with limiting baffles in the transverse direction. The limiting baffles and the B-pillar trim panel body form the mating groove. The damping rubber strips are provided at both ends of the seatbelt sliding plate and cooperate with the corresponding limiting baffles.

[0007] In the aforementioned B-pillar seatbelt sliding plate moving assembly, the damping strip includes an inner damping strip and an outer damping strip, both with a U-shaped cross-section. The end of the seatbelt sliding plate is inserted into the U-shaped groove of the inner damping strip, and the seatbelt sliding plate located on the upper and lower sides of the inner damping strip is provided with limiting step surfaces for restricting the upper and lower positions of the inner damping strip. The U-shaped middle part of the inner damping strip is inserted into the U-shaped groove of the outer damping strip.

[0008] In the aforementioned B-pillar seatbelt sliding plate moving assembly, the end side walls of the seatbelt sliding plate are provided with limiting protrusions along their edges, and the U-shaped inner side wall of the damping inner strip is provided with a limiting groove for engaging with the limiting protrusions.

[0009] In the aforementioned B-pillar seatbelt sliding plate moving assembly, a mating pad is provided on the B-pillar trim panel body located outside the seatbelt sliding plate, and a mating space is formed between the mating pad and the limiting baffle to clamp the seatbelt sliding plate inside and out.

[0010] In the aforementioned B-pillar seatbelt sliding plate moving assembly, a connecting support plate is provided on the B-pillar trim panel body located inside one end of the seatbelt sliding plate. The connecting support plate is provided with a lateral limiting plate that can abut against the side wall of the damping rubber strip to limit the damping rubber strip from moving away from the mating groove. A gap compensation part is provided on the side of the seatbelt sliding plate away from the lateral limiting plate. The minimum lateral distance between the end of the gap compensation part and the bottom surface of the corresponding mating groove is smaller than the minimum lateral distance between the other end of the seatbelt sliding plate and the bottom surface of the corresponding mating groove.

[0011] In the aforementioned B-pillar seatbelt sliding plate moving assembly, the end of the connecting support plate holds a U-shaped sheet metal clamp, and the lateral limiting plate is formed by cutting and bending the U-shaped sheet metal clamp. The U-shaped clamping end of the U-shaped sheet metal clamp is inclinedly provided with a barbed pawl whose tip abuts against the connecting support plate. The barbed pawl can prevent the U-shaped sheet metal clamp from moving away from the connecting support plate.

[0012] The outstanding advantages of this utility model compared to the prior art are:

[0013] This utility model has a simple structure, reasonable design, and low cost. By using the dynamic friction between the damping rubber strip and the matching groove, it can not only compensate for wear in time to ensure that the seat belt slide plate and the B-pillar trim panel are stably matched and do not wobble, but also provide damping feedback to the driver and passengers when adjusting the seat belt height, so that the driver and passengers can make stable and precise adjustments.

[0019] The present invention will be further described below with reference to specific embodiments. See also: Figure 1 —4:

[0020] A B-pillar seatbelt sliding plate moving assembly includes a B-pillar trim panel body 1 and a seatbelt sliding plate 2 that slides vertically on the B-pillar trim panel body 1. The left and right sides of the inner wall of the B-pillar trim panel body 1 are provided with mating grooves in the vertical direction. The two sides of the seatbelt sliding plate 2 are respectively located in the corresponding mating grooves. The side of the seatbelt sliding plate 2 is provided with a damping rubber strip 3 in the inward and outward direction. The damping rubber strip 3 abuts against and dynamically rubs against the inner groove wall of the mating groove.

[0021] This utility model has a simple structure, reasonable design and low cost. With the help of the dynamic friction between the damping rubber strip 3 and the matching groove, it can not only compensate for wear in time to ensure that the seat belt slide plate 2 and the B-pillar trim panel body 1 are stable and do not wobble, but also provide damping feedback to the driver and passengers when adjusting the seat belt height, so that the driver and passengers can make stable and precise adjustments.

[0022] Furthermore, in this embodiment, both the B-pillar trim panel body 1 and the seat belt slide plate 2 have U-shaped cross-sections. Limiting baffles 4 are provided laterally on the inner walls of both shoulder walls of the B-pillar trim panel body 1, forming the mating groove between the limiting baffles 4 and the B-pillar trim panel body 1. The damping strip 3 is disposed at both ends of the seat belt slide plate 2 and mates with the corresponding limiting baffles 4. To assemble the damping strip 3 onto the seat belt slide plate 2 and prevent it from detaching during vertical movement, the damping strip 3 includes an inner damping strip 5 and an outer damping strip 6, both with U-shaped cross-sections. The end of the seat belt slide plate 2 is inserted into the U-shaped groove of the inner damping strip 5, and limiting step surfaces for restricting the vertical position of the inner damping strip 5 are provided on the upper and lower sides of the inner damping strip 5. The U-shaped middle portion of the inner damping strip 5 is inserted into the U-shaped groove of the outer damping strip 6. Meanwhile, it should be noted that the damping strip 3 can also be just one piece. However, in this embodiment, the damping strip 3 is designed as a damping inner strip 5 and a damping outer strip 6 with different coefficients of friction. This is because the damping outer strip 6 and the mating groove need to be in dynamic frictional fit, while the damping inner strip 5 and the seat belt slide plate 2 need to be in static frictional fit.

[0023] In order to facilitate the assembly of the damping inner strip 5 to the end of the seat belt slide plate 2 and to ensure that it will not easily detach, the end side walls of the seat belt slide plate 2 are provided with limiting protrusions along their edges, and the U-shaped inner side wall of the damping inner strip 5 is provided with limiting grooves for the limiting protrusions to engage.

[0024] Furthermore, in order to ensure that the damping strip 3 can always abut against the mating groove during the up and down movement, a mating pad 7 is provided on the B-pillar trim body 1 located outside the seat belt slide plate 2. The mating pad 7 and the limiting baffle 4 form a mating space for clamping the seat belt slide plate 2 inside and out.

[0025] Furthermore, to improve the stability of the seat belt slide plate 2's vertical movement and reduce the amount of lateral displacement, a connecting support plate 8 is provided on the B-pillar trim panel body 1 located on the inner side of one end of the seat belt slide plate 2. The connecting support plate 8 is provided with a lateral limiting plate 9 that abuts against the side wall of the damping strip 3 to limit the damping strip 3 from moving away from the mating groove. A gap compensation part 10 is provided along the edge of the seat belt slide plate 2 away from the lateral limiting plate 9. The minimum lateral distance between the end of the gap compensation part 10 and the bottom surface of the corresponding mating groove is smaller than the minimum lateral distance between the other end of the seat belt slide plate 2 and the bottom surface of the corresponding mating groove. In this embodiment, the connecting support plate 8 and the limiting baffle 4 are an integral structure.

[0026] Furthermore, the specific structure of the transverse limiting plate 9 is as follows: the end of the connecting support plate 8 holds a U-shaped sheet metal clamp 11, the transverse limiting plate 9 is cut and bent from the U-shaped sheet metal clamp 11, and the U-shaped clamping end of the U-shaped sheet metal clamp 11 is inclinedly provided with a barbed pawl 12 whose tip abuts against the connecting support plate 8. The barbed pawl 12 can prevent the U-shaped sheet metal clamp 11 from moving away from the connecting support plate 8.

[0027] The above embodiments are only one of the preferred embodiments of this utility model and are not intended to limit the scope of implementation of this utility model. Therefore, all equivalent changes made in accordance with the shape, structure and principle of this utility model should be covered within the protection scope of this utility model.
