Description

Technical Field

[0001] This utility model relates to the field of automotive seat technology, and more specifically, to an automotive seat return spring fixing structure. Background Technology

[0002] An adjuster is a device installed on a car seat to adjust the seat back angle. After use, the device is reset by a return spring. However, after repeated use, the return spring's elasticity often decreases, causing the adjuster to fail to reset promptly.

[0003] Therefore, it is necessary to provide a car seat return spring fixing structure to solve the above problems. Utility Model Content

[0004] Based on the aforementioned problems in the prior art, the purpose of this application is to provide a car seat return spring fixing structure to achieve the effect of adjusting the return spring force.

[0005] The technical solution adopted by this application to solve its technical problem is: a car seat return spring fixing structure, including an adjuster, the adjuster including a support plate, a support rod and a fixing plate fixed on one side of the support plate, a rotating plate rotatably disposed on the support rod, a slot disposed on the rotating plate, a locking plate disposed in the slot, and an elastic element connecting the locking plate and the fixing plate.

[0006] Furthermore, a housing is fixed to one side of the support plate, and the support rod, fixing plate, and rotating plate are located inside the housing.

[0007] Furthermore, an opening is provided on one side of the housing, and the end of the rotating plate away from the support rod extends out to the outside of the housing through the opening.

[0008] Furthermore, a handle is fixed to the end of the rotating plate away from the support rod.

[0009] Furthermore, a fixing block is fixed on the rotating plate. The fixing block is located at the upper end of the slot. A bolt is provided on the upper side of the fixing block. The lower end of the bolt passes through the fixing block. The bolt is threadedly connected to the fixing block. A rotating shaft is fixed at the lower end of the bolt. A rotating sleeve is rotatably sleeved on the rotating shaft. The clamping plate is fixed to one side of the rotating sleeve.

[0010] The beneficial effect of this utility model is that the elastic force of the elastic element can be adjusted by the up and down movement of the card plate in the card slot.

[0011] During installation, the staff can move the card plate to the bottom of the slot. At this time, the distance between the card plate and the fixed plate is the shortest. When installing the elastic element, it is not necessary to pull the elastic element to a long length. After the elastic element is installed, the bolt can be turned to adjust the elastic force of the elastic element, so as to facilitate the installation of the elastic element.

[0012] During use, users can adjust the elasticity of the elastic element to avoid problems such as excessive elasticity making it difficult to pull the handle, or reduced elasticity after prolonged use making it difficult for the handle to quickly return to its original position.

[0020] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0021] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0022] In this utility model, unless otherwise stated, the orientations used, such as "up" and "down", usually refer to the direction shown in the accompanying drawings, or to the vertical, perpendicular, or gravitational direction; similarly, for ease of understanding and description, "left" and "right" usually refer to the left and right shown in the accompanying drawings; "inner" and "outer" refer to the inner and outer contours of each component itself, but the above directional terms are not used to limit this utility model.

[0023] like Figure 1-3 As shown, this application provides a car seat return spring fixing structure, including an adjuster 1. The adjuster 1 includes a support plate 11 and a housing 12 fixed to one side of the support plate 11. A support rod 13 is fixed to the side of the support plate 11 near the housing 12.

[0024] A rotating plate 2 is rotatably mounted on the support rod 13, and a fixing plate 14 is fixed between one end of the support rod 13 and the lower end of the support plate 11.

[0025] An opening 15 is provided on one side of the outer casing 12. The end of the rotating plate 2 away from the support rod 13 extends out through the opening 15 to the outside of the outer casing 12 and is fixed with a handle 16.

[0026] A slot 21 is provided on the rotating plate 2, and a fixing block 22 is fixed on the rotating plate 2, with the fixing block 22 located at the upper end of the slot 21. A bolt 23 is provided on the upper side of the fixing block 22, with the lower end of the bolt 23 passing through the fixing block 22 and being threadedly connected to the fixing block 22. A rotating shaft 24 is fixed to the lower end of the bolt 23, and a rotating sleeve 25 is rotatably sleeved on the rotating shaft 24. A retaining plate 26 is fixed to one side of the rotating sleeve 25, and the retaining plate 26 is engaged with the slot 21. An elastic element 27 connects the retaining plate 26 and the fixing plate 14.

[0027] Understandably, during use, passengers can turn the rotating plate 2 via handle 16 to activate the seat back adjuster 1 and adjust its angle. After the passenger releases handle 16, the rotating plate 2 is reset via the elastic element 27, thus closing the seat back adjuster 1.

[0028] When the bolt 23 is rotated, the bolt 23 will drive the rotating shaft 24 and the rotating sleeve 25 to move up and down together through the threaded connection between the bolt 23 and the fixing block 22. This will cause the clamping plate 26 to move up and down along the clamping groove 21, thereby stretching or relaxing the elastic element 27 and adjusting the elastic force of the elastic element 27 when the handle 16 is pulled.

[0029] During installation, the operator can move the clamping plate 26 to the bottom of the slot 21, at which point the distance between the clamping plate 26 and the fixing plate 14 is minimized. This eliminates the need to pull the elastic element 27 to a longer length when installing it. After the elastic element 27 is installed, the bolt 23 is rotated to adjust the elasticity of the elastic element 27, facilitating its installation.

[0030] During use, the user can adjust the elastic force of the elastic element 27 at any time by turning the bolt 23 with a screwdriver through the opening 15. This avoids problems such as the elastic element 27 having too much elastic force, making it difficult to pull the handle 16, or the elastic element 27 having reduced elasticity after prolonged use, making it difficult for the handle 16 to quickly return to its original position.
