Description

Technical Field

[0001] This utility model belongs to the field of seat technology, and in particular relates to a guide tube and pull-line positioning device inside the seat cushion frame of a seat. Background Technology

[0002] Currently, the shock absorber ducts and related cables within the seat cushion frame of most seats have not undergone standardized routing. The ducts and cables are haphazardly routed without any constraint points. During prolonged use, the ducts and cables may rub against metal parts or other components, leading to wear and air leakage. They may also kink or bend in narrow spaces, causing duct deformation or cable breakage and kinking. These issues directly affect the ventilation performance of the ducts or the operation and control of the cables, and may even cause the shock absorbers to malfunction, rendering the seat ineffective in shock absorption. Summary of the Invention

[0003] The purpose of this invention is to provide a seat cushion frame inner guide tube and pull line positioning device that can better position, reduce or avoid wear and tear on the guide tubes and pull lines.

[0004] The purpose of this utility model is to solve the following problem:

[0005] A seat cushion frame internal guide tube and pull cable positioning device includes a lower seat cushion frame and a height-adjustable upper seat cushion frame. The upper seat cushion frame is provided with a positioning frame for positioning guide tubes and pull cables. The positioning frame includes an L-shaped positioning plate and its upper cover. The vertical plate of the L-shaped positioning plate is fixed to the side beam of the upper seat cushion frame. The horizontal plate of the L-shaped positioning plate is provided with upwardly extending spacers along the length direction. A gap is reserved between adjacent spacers for placing guide tubes or pull cables. The upper cover is snapped onto the top of the spacers to cover all the spacers. The guide tubes and pull cables connecting to the shock absorbers in the seat cushion frame pass through the gaps between adjacent spacers and are thus positioned relative to each other.

[0006] As a further optimization of the above technical solution, the middle of the horizontal plate of the L-shaped positioning plate is provided with a strip hole along the length direction to form the side plates on both sides and the front end plate at the end. The front end plate extends upward to the same height as the spacer, and a forward-extending snap-fit ​​block is provided on its upper front part. A groove is provided on the horizontal plate near the vertical plate, and upper cover snap-fit ​​grooves are provided on the two side walls of the groove.

[0007] As a further optimization of the above technical solution, the vertical plate of the L-shaped positioning plate is provided with mounting holes, and the L-shaped positioning plate is fixed to the side beam through the mounting holes on the vertical plate and bolts.

[0008] As a further optimization of the above technical solution, the spacer is a partition plate, the two ends of the partition plate are integrally formed with the side plates on both sides of the horizontal plate, and the lower two sides of the partition plate are respectively formed with reinforcing plates between them and the horizontal plate.

[0009] As a further optimization of the above technical solution, the reinforcing plate is a right-angled triangle plate, with the two right-angled sides of the right-angled triangle plate formed on the partition and the horizontal plate, respectively.

[0010] As a further optimization of the above technical solution, positioning strips are integrally formed on the upper two sides of the partition.

[0011] As a further optimization of the above technical solution, the cross-section of the snap-fit ​​block is triangular, and the upper surface of the snap-fit ​​block is a slope that slopes forward and downward.

[0012] As a further optimization of the above technical solution, the upper cover is a strip plate, and short shafts that are snapped into the snap-fit ​​grooves on the horizontal plate are respectively provided on the rear two sides of the strip plate. The front part of the strip plate is provided with a snap-fit ​​groove or snap-fit ​​hole that is snapped into the snap-fit ​​block.

[0013] As a further optimization of the above technical solution, the lower surface of the strip plate is provided with protrusions on both sides extending toward the gap between adjacent spacers.

[0014] As a further optimization of the above technical solution, the protrusion and the positioning strips integrally formed with the partition are respectively matched on the upper two sides of the partition.

[0015] The advantages of this invention compared to the prior art are:

[0016] 1. This utility model utilizes a positioning bracket fixed to the side beam of the seat cushion frame to position the air duct and control cable of the shock absorber within the seat cushion frame. This not only allows for better positioning of the duct and cable within the seat cushion frame but also facilitates the installation and maintenance of related components. In particular, when inspecting the duct and cable, it allows for direct and clear observation of the relevant duct and cable. It also reduces or avoids malfunctions such as wear and air leakage, difficulty in operation, or abnormal noise caused by friction, collision, kinking, or entanglement between the duct and cable and metal parts or other components, or kinking or entanglement in narrow places. This improves the safety and maintainability of the seat, extends the product's service life, and realizes a platform-based and modular layout of the duct and cable within the seat cushion frame, which is conducive to the standardized production of the seat.

[0017] 2. The L-shaped positioning plate and the top cover of this utility model are connected by a snap-fit, which facilitates the disassembly, assembly, and maintenance of the conduit and pull wire, and provides good maintainability.

[0018] 3. The protrusions on the lower surface of the strip plate of this utility model match the positioning strips integrally formed with the partition plate on both sides of the upper part of the partition plate, which restricts the conduit and the pull wire within the gap X under the positioning strip and the protrusion, resulting in good positioning effect and no interference between conduits and between pull wires.

[0019] 4. This utility model has a simple structure, is easy to install and operate, and has low production cost. It is suitable for positioning the guide tube and pull wire inside the seat cushion frame of a chair. Attached Figure Description

[0030] As a further optimization of the above technical solution, the spacer 44 is a partition plate, and the two ends of the partition plate are integrally formed with the side plates 431 on both sides of the horizontal plate 43. Reinforcing plates 51 are respectively formed between the lower two sides of the partition plate and the horizontal plate 43.

[0031] As a further optimization of the above technical solution, the reinforcing plate 51 is a right-angled triangle plate, with the two right-angled sides of the right-angled triangle plate formed on the partition (spacer 44) and the horizontal plate 43, respectively.

Place the air supply pipe, exhaust pipe and control cable of the shock absorber in the reserved gap X between adjacent spacers in sequence. After fitting the short shaft 31 of the upper cover 30 onto the snap-fit ​​groove 50 on the horizontal plate 43, rotate the upper cover 30 so that the snap-fit ​​groove or snap-fit ​​hole 34 of the upper cover 30 snaps into the snap-fit ​​block 45 of the horizontal plate 43 of the L-shaped positioning plate 40. This completes the assembly and use of the positioning frame. Flip the upper cover 30 so that the snap-fit ​​groove or snap-fit ​​hole 34 on the upper cover 30 disengages from the snap-fit ​​block 45 on the horizontal plate 43 of the L-shaped positioning plate 40. This is to open the upper cover 30 and disassemble and repair the related pipes 13 and cables.
