Description

Technical Field

[0001] This utility model relates to the field of automotive seat technology, specifically to an automotive seat cushion that allows for adjustment of the front and back of the seat according to seasonal temperature. Background Technology

[0002] With the development of the automotive industry and the improvement of people's living standards, people have increasingly higher requirements for the comfort of car seats. The seat cushion fabric directly affects the comfort of riding. Currently, the seat cushion fabrics on the market are usually fixed, commonly including leather and fabric. Leather fabric has a high-end appearance and is easy to clean, but in cold winters, it can feel cold and uncomfortable; in hot summers, its poor breathability can make people feel stuffy. Fabric fabric is relatively warm in winter and has good breathability in summer, but its appearance and ease of cleaning are not as good as leather. Existing car seat cushions cannot flexibly switch fabrics according to seasonal temperature changes, making it difficult for users to obtain the best riding experience in different seasons. Therefore, there is an urgent need for a car seat cushion that can adjust the front and back of the seat according to seasonal temperature to solve the above problems. Utility Model Content

[0003] The purpose of this invention is to provide an adjustable car seat cushion with both front and back sides, in order to solve the problem that the existing car seat cushion fabric is fixed and cannot be flexibly switched according to seasonal temperature, resulting in poor riding comfort.

[0004] An aircraft seat cushion includes a seat frame, a backrest, a seat, and a side panel disposed on the seat frame. The seat frame is fixedly connected to the seat via a disassembly / removal assembly, which includes a pair of guide rails and a limiting mechanism fixed on the seat frame, a pair of guide cavities disposed on the seat, and a limiting hole formed on the seat.

[0005] The limiting mechanism includes a slide cylinder fixed to the seat frame, a reduction motor fixed to the bottom of the slide cylinder, a lead screw extending into the slide cylinder via the output shaft of the reduction motor, a pair of guide grooves on the slide cylinder, a limiting rod inside the slide cylinder, a pair of guide blocks on the limiting rod, and threaded holes on the limiting rod, which is threadedly connected to the lead screw through the threaded holes. The front of the seat is made of leather, and the back is made of fabric.

[0006] Furthermore, the guide rail has a T-shaped or inverted T-shaped cross-section, and the inner wall of the guide cavity is provided with a T-shaped or inverted T-shaped groove that matches the guide rail, allowing the guide rail and the guide cavity to slide and engage. This structure ensures that the chair seat slides stably on the seat frame, while also facilitating installation and disassembly.

[0007] The geared motor is electrically connected to a control switch mounted on the seat surface. The control switch controls the forward and reverse rotation of the geared motor, which in turn drives the lead screw to rotate, causing the limit rod to move up and down. By operating the control switch, the user can raise or lower the limit rod, thereby fixing or unlocking the seat.

[0008] The guide groove is adapted to the guide block, and the guide block slides up and down inside the guide groove, thereby limiting the circular motion of the limiting rod. This ensures that the limiting rod does not rotate during its up and down movement, guaranteeing its accurate insertion or disengagement from the limiting hole.

[0009] The limiting rod has a spherical structure at its top, which is adapted to fit the limiting hole on the chair seat. The spherical structure allows the limiting rod to be inserted into the limiting hole more smoothly, while improving the stability of the connection.

[0010] The external thread of the lead screw and the internal thread of the threaded hole are trapezoidal or rectangular threads, and the thread pitch is 2-5mm to ensure the movement accuracy and stability of the limit rod. Trapezoidal or rectangular threads have good transmission efficiency and load-bearing capacity, and a suitable thread pitch can ensure that the limit rod moves slowly and smoothly.

[0011] Both the slide cylinder and the limiting rod are made of aluminum alloy or carbon fiber. The surfaces of the guide rail and guide cavity are coated with a wear-resistant coating to improve the strength and service life of the components. Aluminum alloy or carbon fiber materials are lightweight and high-strength, and the wear-resistant coating can reduce wear between components and extend the service life of the entire seat cushion.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] By incorporating a convenient disassembly and retraction component, the chair seat can slide on the seat frame, and a limiting mechanism enables the seat to be fixed and unlocked. Users can adjust the seat position by controlling a switch to operate the reduction motor, causing the limiting rod to descend and release the seat's restriction. The seat can then slide along the guide rail, flipping it so the leather or fabric side faces upwards. The reduction motor then raises the limiting rod again, inserting it into the limiting hole to secure the seat. This allows for seat adjustment, meeting users' seasonal preferences for seat fabric and improving seating comfort. Attached Figure Description

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.

[0024] Example 1

[0025] like Figure 1-6 As shown;

[0026] A seat cushion for aircraft seats.

[0027] This implementation plan addresses the technical problems existing in the prior art, as disclosed in the background section above: "With the development of the automotive industry and the improvement of people's living standards, people have increasingly higher requirements for the comfort of car seats. The seat cushion fabric directly affects the comfort of riding. Currently, the seat cushion fabrics on the market are usually fixed, commonly including leather and fabric. Leather fabric has a high-end appearance and is easy to clean, but in cold winters, it can feel cold and uncomfortable; in hot summers, it has poor breathability and can make people feel stuffy. Fabric fabric is relatively warm in winter and has good breathability in summer, but its appearance and ease of cleaning are not as good as leather. Existing car seat cushions cannot flexibly switch fabrics according to seasonal temperature changes, making it difficult for users to obtain the best riding experience in different seasons." In practical terms, this problem is clearly a real and difficult-to-solve issue. Therefore, to solve this technical problem, a seat cushion for aviation seats is provided.

[0028] like Figure 1-6 As shown in the figure;

[0029] This utility model provides a technical solution: a seat cushion for an aircraft seat, including a seat frame 1, and a backrest 11, a seat 12, and a side 13 disposed on the seat frame 1. The seat frame 1 is fixedly connected to the seat 12 via a portable assembly 2. The portable assembly 2 includes a pair of guide rails 21 and a limiting mechanism 22 fixed on the seat frame 1, a pair of guide cavities 23 disposed on the seat 12, and a limiting hole 24 opened on the seat 12.

[0030] The limiting mechanism 22 includes a slide cylinder 221 fixed to the seat bracket 1. A reduction motor 222 is fixed to the bottom of the slide cylinder 221. The output shaft of the reduction motor 222 extends into the slide cylinder 221 and is equipped with a lead screw 223. A pair of guide grooves 224 are provided on the slide cylinder 221. A limiting rod 225 is provided inside the slide cylinder 221. A pair of guide blocks 226 are provided on the limiting rod 225. A threaded hole 227 is provided on the limiting rod 225. The limiting rod 225 is threadedly connected to the lead screw 223 through the threaded hole 227. The front of the seat 12 is leather, and the back is fabric.

[0031] The guide rail 21 has a T-shaped cross-section, and the inner wall of the guide cavity 23 has a T-shaped groove that matches the guide rail 21, so that the guide rail 21 and the guide cavity 23 form a sliding engagement. Of course, the cross-section of the guide rail 21 can also be an inverted T-shaped structure, and the inner wall of the guide cavity 23 can be correspondingly provided with an inverted T-shaped groove, which can also achieve a sliding engagement.

[0032] The geared motor 222 is electrically connected to a control switch located on the surface of the seat 12. The control switch can be a push-button switch, located on the surface of the seat 12 in a position convenient for the user to operate. When the user presses the control switch, the geared motor 222 can be controlled to rotate in both directions. When the geared motor 222 rotates in the forward direction, the lead screw 223 rotates, causing the limit rod 225 to rise; when the geared motor 222 rotates in the reverse direction, the lead screw 223 rotates, causing the limit rod 225 to fall.

[0033] The guide groove 224 is adapted to the guide block 226. The size of the guide block 226 is slightly smaller than the size of the guide groove 224, so that the guide block 226 can slide up and down inside the guide groove 224, while restricting the circumferential movement of the limiting rod 225, ensuring that the limiting rod 225 can only move up and down.

[0034] The top of the limiting rod 225 is provided with a spherical structure, and the diameter of the limiting hole 24 is slightly larger than the diameter of the spherical structure, so that the top of the limiting rod 225 can be smoothly inserted into the limiting hole 24, and the chair seat 12 can be stably fixed after insertion.

[0035] The external thread of the lead screw 223 and the internal thread of the threaded hole 227 are trapezoidal threads with a pitch of 3mm. Trapezoidal threads have good transmission efficiency and load-bearing capacity, and the 3mm pitch ensures the movement accuracy and stability of the limit rod 225. Of course, rectangular threads can also be used, with a pitch between 2-5mm.

[0036] Both the slide cylinder 221 and the limiting rod 225 are made of aluminum alloy, which is lightweight and high-strength, making it suitable for use in car seat cushions. The surfaces of the guide rail 21 and the guide cavity 23 are coated with a wear-resistant coating, such as a ceramic coating or a polytetrafluoroethylene coating, which can reduce wear between the guide rail 21 and the guide cavity 23 and improve the service life of the components.

[0037] Working principle

[0038] When the user needs to adjust the front and back of the seat 12 according to the seasonal temperature, first press the control switch set on the surface of the seat 12 to control the geared motor 222 to reverse. The output shaft of the geared motor 222 drives the lead screw 223 to reverse. Since the limit rod 225 is threadedly connected to the lead screw 223 through the threaded hole 227 and the guide block 226 slides inside the guide groove 224, the circumferential movement of the limit rod 225 is limited. Therefore, the limit rod 225 will move downward along the lead screw 223. When the spherical structure at the top of the limit rod 225 completely disengages from the limit hole 24 on the seat 12, the limitation on the seat 12 is released.

[0039] Then, the user can slide the seat 12 outward along the guide rail 21 until the seat 12 is completely separated from the seat support 1 (or slide it to a position that is easy to flip), and then flip the seat 12 180 degrees so that the original reverse side (fabric side) is up and the original front side (leather side) is down, or vice versa (depending on seasonal needs).

[0040] Next, slide the flipped chair seat 12 back onto the seat bracket 1 along the guide rail 21, so that the guide cavity 23 and the guide rail 21 re-establish a sliding engagement. Press the control switch again to control the geared motor 222 to rotate forward. The output shaft of the geared motor 222 drives the lead screw 223 to rotate forward, and the limit rod 225 moves upward along the lead screw 223. When the spherical structure at the top of the limit rod 225 is inserted into the limit hole 24 on the chair seat 12, the chair seat 12 is fixed.

[0041] Through the above operations, the front and back of the seat 12 can be adjusted. In winter, users can face up with the fabric side up for a warm riding experience; in summer, they can face up with the leather side up for better breathability and coolness.

[0042] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model 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 this utility model should be included within the protection scope of this utility model.
