Description
Technical Field
[0001] This utility model relates to the field of automotive parts technology, and in particular to an automotive seat. Background Technology
[0002] Car seats and headrests are important components of a vehicle's passive safety system. Working together, they provide comfort, support, and safety for occupants. Car seats offer body support, distributing weight and reducing fatigue during long drives or rides. Ergonomic designs, such as lumbar support and side bolsters, enhance comfort. The angle and height of the headrest and seat back must be coordinated to ensure a natural fit for the head. A forward-protruding headrest design can actively shift forward during a collision, shortening the gap between the head and the headrest and improving support for the neck and head.
[0003] To better accommodate people of different heights, height-adjustable headrests are usually installed on car seats. There are generally two ways to adjust the car seat and headrest: one is manual adjustment, which involves pressing the button or buckle on the side of the headrest, sliding it up or down to the desired position, and then locking it for adjustment; the other is electric adjustment, with a few luxury models supporting button adjustment.
[0004] Manual adjustment is more commonly used, but it involves inserting the headrest support into the metal sleeve of the seat back. The headrest support has a slot on its side wall, and a spring pin locks into the slot to fix the height, making it difficult to achieve stepless adjustment of the headrest height. In addition, when adjusting the headrest support, it is necessary to pry off the cover that hides the spring pin, which is difficult to do, making it quite strenuous to adjust the headrest height. Utility Model Content
[0005] To address the shortcomings of existing technologies, this utility model provides a car seat that solves the problem that it is difficult to achieve stepless adjustment of the headrest height when the headrest support has a slot on its side wall and a spring pin is fixed to the slot.
[0006] To achieve the above objectives, the basic solution of this utility model is as follows: A car seat, comprising a seat body, a headrest, and a height adjustment unit located between the seat body and the headrest, the height adjustment unit comprising:
[0007] Insertion rod, the end of which is fixedly installed on the side of the headrest near the seat body;
[0008] The cover is fixedly installed on the side of the seat body near the headrest, and the cover has mounting holes for the insertion rod to pass through for installation;
[0009] The fixing tube is fixedly installed inside the seat body. The upper end of the fixing tube is fixedly connected to the shell cover and coaxially communicates with the mounting hole. The insert rod can be coaxially embedded into the fixing tube.
[0010] A locking clamp that can clamp the insert rod is coaxially mounted at the mounting hole of the cover. The locking clamp is provided with a hinge shaft and a first wing plate and a second wing plate located at the opening end of the locking clamp. The end of the hinge shaft is fixedly connected to the cover. The side wall of the cover is provided with actuation holes for the first wing plate and the second wing plate to extend. The first wing plate and the second wing plate can rotate horizontally at the actuation holes. Locking elements are provided on the first wing plate and the second wing plate.
[0011] The technical principle of this utility model is as follows: When adjusting the headrest height, the locking parts on the first and second wing plates are loosened, separating the first and second wing plates from the actuation hole, thereby causing the locking clamp to rotate relative to the hinge shaft, and simultaneously loosening the insertion rod; at this time, the user can press or lift the headrest to adjust the headrest height; after the headrest height is adjusted to the correct position, the first and second wing plates are then moved to close the locking clamp, and the locking parts are used to lock the first and second wing plates. The locking clamp can then lock and clamp the insertion rod, thereby fixing the headrest height.
[0012] During the height adjustment process described above, the connection position between the insert rod and the locking clamp can be adjusted steplessly, thereby precisely adjusting the installation height of the headrest and improving the overall comfort of the headrest and seat body. When adjusting the headrest height, simply control the contact state of the first or second wing plate through the toggle hole to lock or release the insert rod. The locking control of the insert rod is convenient and easy to adjust, and the adjustment is also more flexible.
[0013] Furthermore, the locking element is located on the end of the first wing plate and the second wing plate outside the actuation hole.
[0014] The above-mentioned design makes it easier to operate the locking mechanism through the toggle hole, making the locking or unlocking of the first and second wing plates more convenient.
[0015] Furthermore, the locking element includes:
[0016] The buckle can be rotated and engaged to be pressed against the outside of the first and second wing plates;
[0017] A fixed shaft is fixedly installed on the outer wall of the first or second wing plate.
[0018] A rotating ring is coaxially mounted on a fixed shaft. A portion of the outer wall of the retaining ring is fixedly connected to the outer wall of the rotating ring. The axis of the fixed shaft is perpendicular to the axis of the retaining ring.
[0019] With the above configuration, when the first and second wing plates are loosened, the buckle located on the first or second wing plate can be flipped around the fixed axis and rotating ring; conversely, the first and second wing plates are locked. The locking and loosening operations are simple and reliable, and the buckle is stably installed on the first or second wing plate, making the use of the buckle convenient and stable.
[0020] Furthermore, the end of the locking clamp abuts against the top of the fixing tube.
[0021] With the above settings, when the insert rod is inserted into the locking clamp and the fixing tube, there is no gap between the locking clamp and the fixing tube, which makes the downward insertion of the insert rod stable and fast.
[0022] Furthermore, a first elastic anti-slip plate is fixedly installed on the inner wall of the locking clamp, and the first anti-slip plate can abut against the insert rod.
[0023] With the above settings, after the buckle is fastened and locked, the elastic first anti-slip piece can be compressed and then tightly adhered to the outer wall of the insert rod, so that the installation limit of the insert rod and the headrest is stable.
[0024] Furthermore, a second elastic anti-slip plate is fixedly installed on the inner wall of the fixed tube, and the second anti-slip plate can fit against the insertion rod.
[0025] With the above settings, during the loosening adjustment process, the second anti-slip plate remains in contact with the anti-slip texture on the outer wall of the insert rod, and the insert rod will not slide freely vertically relative to the shell cover and the fixing tube, which facilitates the pre-adjustment and locking of the insert rod and the headrest; at the same time, it can reinforce the height locking of the insert rod and the headrest.
[0026] Furthermore, a first notch is vertically penetrating the first wing plate on the side near the second wing plate, and a second notch that can be fitted together with the first notch is vertically penetrating the second wing plate on the side near the first wing plate. The first notch is located on the end of the first wing plate away from the hinge axis, and the second notch is located on the end of the second wing plate away from the hinge axis.
[0027] With the above configuration, when separating the loose first and second wing plates, it is easy for a person to insert their hand into the first and second notches, thereby facilitating the separation of the first and second wing plates and reducing the difficulty of disassembling the first and second wing plates.

Detailed Implementation
[0033] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.
[0034] This embodiment is basically as follows: Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this utility model embodiment proposes a car seat, including a seat body 10, a headrest 20, and a lifting adjustment unit located between the seat body 10 and the headrest 20. The number of lifting adjustment units is two, and the two lifting adjustment units are symmetrically arranged with respect to the vertical center line of the headrest 20.
[0035] like Figure 2-4 As shown, the height adjustment unit includes an insertion rod 30, a cover 40, a fixing tube 50, and a locking clamp 60 that can clamp the insertion rod 30. The upper end of the insertion rod 30 is fixedly installed on the lower side of the headrest 20. The cover 40 is fixedly installed at the middle of the top side of the seat body 10, and the cover 40 is provided with a mounting hole for the insertion rod 30 to pass through. At the same time, the fixing tube 50 is fixedly installed inside the seat body 10. The upper end of the fixing tube 50 is fixedly connected to the cover 40 and coaxially communicates with the mounting hole. The insertion rod 30 can be coaxially embedded into the fixing tube 50.
[0036] like Figure 4As shown, the locking clamp 60 is coaxially mounted at the mounting hole of the cover 40. The locking clamp 60 is provided with a hinge shaft and a first wing plate 602 and a second wing plate 603 located at the opening end of the locking clamp 60. The end of the hinge shaft is fixedly connected to the cover 40 by screws. The side wall of the cover 40 is provided with a lever hole 401 for the first wing plate 602 and the second wing plate 603 to extend out. The lever hole 401 faces the front side of the seat body 10. The first wing plate 602 and the second wing plate 603 can rotate horizontally at the lever hole 401. The first wing plate 602 and the second wing plate 603 are provided with locking members. The locking members are located at the ends of the first wing plate 602 and the second wing plate 603 outside the lever hole 401. The end of the locking clamp 60 abuts against the top end of the fixing tube 50.
[0037] At the same time, such as Figure 4 As shown, the locking component includes a retaining ring 604, a fixed shaft 605, and a rotating ring 606. The retaining ring 604 can be rotatably engaged and pressed against the outside of the first wing plate 602 and the second wing plate 603. The fixed shaft 605 is fixedly installed on the outer wall of the second wing plate 603 via a connecting block. The rotating ring 606 is coaxially rotatably installed on the fixed shaft 605. A portion of the outer wall of the retaining ring 604 is fixedly connected to the outer wall of the rotating ring 606. The axis of the fixed shaft 605 is perpendicular to the axis of the retaining ring 604. A first notch 607 is vertically penetrating the first wing plate 602 near the side of the second wing plate 603. A second notch 608, which can be joined with the first notch 607, is vertically penetrating the second wing plate 603 near the side of the first wing plate 602. The first notch 607 is located on the left end of the first wing plate 602, and the second notch 608 is located on the left end of the second wing plate 603.
[0038] In addition, such as Figure 4 As shown, an elastic first anti-slip piece 601 is fixedly installed on the inner wall of the locking clamp 60, and the first anti-slip piece 601 can abut against the insertion rod 30; an elastic second anti-slip piece 501 is fixedly installed on the inner wall of the fixing tube 50, and the second anti-slip piece 501 can fit against the insertion rod 30; both the first anti-slip piece 601 and the second anti-slip piece 501 are made of elastic rubber; when the first wing plate 602 and the second wing plate 603 are closed and pressed together, the first anti-slip piece 601 is compressed and fitted against the outer wall of the insertion rod 30, and the outer wall of the insertion rod 30 is provided with anti-slip texture.
[0039] In this embodiment, when adjusting the height of the headrest 20, the buckle 604 located on the first wing plate 602 or the second wing plate 603 is first flipped around the fixed axis 605 and the rotating ring 606, causing the buckle 604 to disengage from the first wing plate 602 or the second wing plate 603, thereby loosening the locking clamp 60. At this time, the user's index finger and thumb simultaneously insert into the first notch 607 and the second notch 608, and the index finger and thumb press the first wing plate 602 in the lifting adjustment unit on both sides, causing the two first wing plates 602 to... 2. When they move closer to each other, the first wing plate 602 and the second wing plate 603 in a single lifting adjustment unit move away from each other. The first wing plate 602 drives one side of the locking clamp 60 to rotate relative to the hinge axis, thereby loosening the locking clamp 60 on the insertion rod 30. At this time, the user can press or lift the headrest 20 to achieve pre-adjustment of the height of the headrest 20. During the loosening adjustment process, the second anti-slip plate 501 and the anti-slip texture on the outer wall of the insertion rod 30 remain in contact, and the insertion rod 30 will not slide vertically and freely relative to the shell cover 40 and the fixing tube 50.
[0040] After the headrest 20 is adjusted to the required height, the first wing plate 602 and the second wing plate 603 in the single lifting adjustment unit are pressed together, and the buckle 604 is fastened to the first wing plate 602 and the second wing plate 603, so that the first anti-slip piece 601 on the inner wall of the locking clamp 60 is pressed against the anti-slip texture on the outer wall of the insert rod 30.
[0041] During the above process, the connection position between the insertion rod 30 and the locking clamp 60 can be steplessly adjusted, thereby precisely adjusting the installation height of the headrest 20 and improving the overall comfort of the headrest 20 and the seat body 10 during use. At the same time, when adjusting the height of the headrest 20, the insertion rod 30 can be locked or loosened by controlling the contact state of the first wing plate 602 or the second wing plate 603 through the toggle hole 401. The locking control of the insertion rod 30 is convenient and the adjustment is easy and flexible.
[0042] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
