Description

Technical Field

[0001] This invention relates to the field of seating technology, and more specifically, to a type of seating. Background Technology

[0002] Seat armrests, as an important component for improving passenger comfort, are widely used in various vehicles. To reduce packing volume during transportation, seat armrests are typically designed as detachable structures. Currently, there are various methods for detachable connection between the armrest and the seat body, among which the connection scheme using a locking mechanism to achieve folding or adjustment is widely used. A common design features a single locking tongue on the armrest, with a corresponding locking hole on the support component. During installation, this single locking tongue is inserted into the locking hole of the support component, achieving point connection and locking between the armrest component and the support component at a single location. This single-point locking structure is widely used in various seating products due to its simplicity and ease of operation.

[0003] However, the existing single-latch latching structure has significant shortcomings in practical use. Because it only forms a single engagement point with the support component via a single latch, this single connection point becomes the only stress point when the seat is subjected to external impact or severe vibration. This causes the armrest component to wobble relative to the support component, resulting in a weak connection, wear on the latch, and even the risk of the latch loosening or detaching after prolonged use, affecting the overall stability and safety of the seat. Summary of the Invention

[0004] To address the problem of insecure single-latch connection in seat construction, this invention provides a seat comprising:

[0005] Support components;

[0015] The combined state also includes: the snap-fit ​​groove abutting against the fixing member, the second locking tongue engaging with the snap-fit ​​hole and abutting against the side of the fixing member near the base, and at least part of the belt unit moving away from the connecting housing, causing the connecting housing and the second locking tongue to rotate toward the base.

[0016] Optionally, the telescopic unit may also include: a pressing groove, a slide, and an elastic part;

[0017] The pressing groove is formed on the connecting housing and is located on the side of the connecting housing away from the base; at least part of the second locking tongue extends into the pressing groove along the extending direction of the connecting housing.

[0018] The elastic part is provided inside the connecting housing along the extension direction of the connecting housing, and the two ends of the elastic part are respectively connected to the connecting housing and the second locking tongue;

[0019] The slide rail is located inside the connecting housing along the extension direction of the connecting housing and is slidably connected to the second locking tongue;

[0020] The extension and retraction of the elastic part causes the second locking tongue to slide along the slide, thereby causing the second locking tongue to extend into or away from the locking groove.

[0021] Optionally, the fixing unit further includes a fixing hole; the fixing hole is located on the side of the base and is spaced apart from the fixing groove on the same side of the base; the combined state includes: the fixing hole engaging with the first locking tongue.

[0022] Optionally, the belt unit includes a waist belt portion disposed around the periphery of the base; the constraint state includes: the waist belt portion is wrapped around one side of the base and fixed to the other side of the base.

[0023] Optionally, the belt unit also includes a shoulder strap portion; the shoulder strap portion spans over the base, and both ends of the shoulder strap portion are connected to both ends of the waist belt portion.

[0029] To solve the problem of insecure single-latch connection of the seat, the present invention has the following advantages:

[0030] The dual-point locking structure formed by the first and second locking areas allows the load to be shared by both areas when the armrest assembly is subjected to external impact or severe vibration. This effectively disperses the impact force, greatly reducing the swaying of the armrest assembly relative to the support assembly and making the connection more secure. Secondly, due to the dispersion of force, the wear of individual locking points is reduced, thereby avoiding the risk of the locking tongue loosening or disengaging due to long-term use, extending the product's service life, and significantly improving the overall structural stability and safety of the seat.

In addition, the terms "installed", "set up", "equipped with", "connected", and "linked" should be interpreted broadly. For example, it can be a fixed connection, a detachable connection, or an integral structure; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or an internal connection between two devices, elements, or components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

Unless otherwise stated, "a plurality of" means two or more.

[0046] To reduce packing volume during transportation, seat armrests are typically designed as detachable structures. For vehicles with high safety and stability requirements, such as car seats, high-speed rail seats, or airplane seats, the armrests need to withstand the instantaneous impact force from the passenger's arms when traveling on bumpy roads or encountering emergencies such as sudden braking or collisions. In these situations, the reliability of the connection between the armrest and the seat body directly affects passenger safety and riding experience. In existing technologies, for non-fixed armrest connection methods, a locking tongue is usually provided on the armrest, and correspondingly, a locking hole is provided on the support component 10. During installation, the single locking tongue is inserted into the locking hole of the support component 10 to achieve point connection and locking between the armrest component 30 and the support component 10 at a single location. However, the existing single-latch latching structure has obvious shortcomings in actual use. Since only one latch forms a single engagement point with the support component 10, when the seat is subjected to external impact or severe vibration, this single connection point becomes the only stress point. This not only causes the armrest component 30 to wobble relative to the support component 10 and the connection to be unstable, but also makes the latch prone to wear under long-term stress, and there is even a risk that the latch may loosen or detach, which seriously affects the overall stability and safety of the seat.

[0047] Example 1:

[0048] This embodiment discloses a seat, such as Figure 1 , Figure 2 and Figure 11 As shown, the seat includes: a support assembly 10 for providing support to the passenger; at least one handhold assembly 30, including a connecting housing 31, a first locking tongue 32 and a telescopic unit 33, wherein the first locking tongue 32 and the telescopic unit 33 are disposed on the connecting housing 31 and are spaced apart along the extension direction of the connecting housing 31, thereby ensuring that the first locking tongue 32 and the telescopic unit 33 each have their own independent working space.

[0049] The seat's assembly configuration includes: a first locking tongue 32 inserted into the support assembly 10, forming a first engagement area. This first engagement area serves as both an initial connection point, providing pre-positioning without requiring simultaneous alignment of two points, and a rotational fulcrum for subsequent rotation. The connecting housing 31 rotates around the first engagement area toward the support assembly 10 until the telescopic unit 33 engages with the support assembly 10, forming a second engagement area. This establishes a dual-point locking structure between the armrest assembly 30 and the support assembly 10. This dual-point locking structure ensures that when the armrest assembly 30 is subjected to external impact or severe vibration, the load is shared by the first and second engagement areas, effectively dispersing the impact force and significantly reducing the swaying of the armrest assembly 30 relative to the support assembly 10, making the connection more secure. Secondly, due to the distributed force, the wear of individual engagement areas is reduced, thus avoiding the risk of the locking tongue loosening or disengaging due to long-term use and severe collisions, extending the product's service life, and significantly improving the overall structural stability and safety of the seat.

[0050] Furthermore, such as Figure 2 and Figure 3 As shown, the support assembly 10 includes a base 11 and a fixing unit 12; the base 11 provides support for the passenger, and the fixing unit 12 is used to connect the first locking tongue 32 and the telescopic unit 33; the fixing unit 12 includes a fixing groove 121 and a fixing member 122; the fixing groove 121 is opened on the side of the base 11; the fixing member 122 is disposed in the fixing groove 121 and forms a snap-fit ​​hole 123 with the fixing groove 121.

[0051] The combined state includes: the snap-fit ​​hole 123 and the telescopic unit 33 engaging with each other, making the engagement between the telescopic unit 33 and the support assembly 10 more stable and reliable. When the telescopic unit 33 is inserted into the snap-fit ​​hole 123, the fixing groove 121 and the fixing member 122 together form a circumferential limit on the telescopic unit 33, effectively restraining its displacement in multiple directions, preventing it from coming out due to vibration or impact, and ensuring the connection reliability of the second engagement area.

[0052] Furthermore, such as Figure 6 and Figure 10As shown, the telescopic unit 33 includes a second locking tongue 331 and a snap-fit ​​groove 332. The snap-fit ​​groove 332 is formed on the connecting housing 31 and is located on the side of the connecting housing 31 near the base 11. The snap-fit ​​groove 332 provides a space for the fixing member 122, effectively reducing the overall volume of the seat. Furthermore, it provides telescopic space for the second locking tongue 331, facilitating the switching between the combined and uncombined states of the second locking tongue 331. The second locking tongue 331 is located on the connecting housing 31, and at least a portion of the second locking tongue 331 extends into the snap-fit ​​groove 332 along the extending direction of the connecting housing 31. In the combined state, the second locking tongue 331 extends into the snap-fit ​​hole 123. Inside, the locking groove 332 limits the fixing member 122 in three directions: up and down, and away from the base 11. This limits the second locking tongue 331 in three directions, and together with the fixing groove 121, it keeps the second locking tongue 331 in a stable position within the locking hole 123. In the event of an impact or shaking, the second locking tongue 331 can only move towards the base 11 due to the multi-directional restrictions. At this time, the locking groove 332 abuts against the fixing member 122, and the two form a surface contact support, which can significantly reduce the wear on the second locking tongue 331 and make the connecting housing 31 more tightly protect the passenger.

[0053] The seat also includes a restraint assembly 20, which includes a belt unit 22. The belt unit 22 is located around the base 11. Specifically, the belt unit 22 is located on the external seat to provide safety restraint for passengers sitting on the base 11. Under normal conditions, the belt unit 22 is in a released state under the action of the existing seat belt retractor. The belt unit 22 also includes a restrained state: at least a portion of the belt unit 22 is wrapped around one side of the base 11 and fixed to the other side of the base 11. In the restrained state, when the belt unit 22 moves in the direction of passenger movement under the action of the passenger, the passenger's action can be self-driven or inertial action during collisions or sudden stops of external vehicles. The belt unit 22 absorbs some of the impact energy and plays a buffering role.

[0054] The combined state also includes: the snap-fit ​​groove 332 abutting against the fastener 122, the second locking tongue 331 engaging with the snap-fit ​​hole 123 to form a second engaging area, the second locking tongue 331 abutting against the side of the fastener 122 near the base 11, and at least part of the belt unit 22 moving away from the connecting housing 31, causing the connecting housing 31 and the second locking tongue 331 to rotate toward the base 11, making the snap-fit ​​groove 332 and the fastener 122 abut more tightly, reducing the wear of the second locking tongue 331, and making the armrest assembly 30 fit more closely to the passenger to provide better safety protection, fundamentally improving the seat's impact resistance and long-term reliability under complex working conditions; since the impact mainly acts on the fastener 122 and the snap-fit ​​groove 332, the first locking tongue 32 and the second locking tongue 331 do not need to have very high strength, saving material costs and improving service life.

[0055] In another embodiment, the second locking tongue 331 is engaged in the portion of the engagement hole 123, and the surface away from the fixing member 122 is an inclined surface. This inclined surface is inclined downward relative to the upper surface of the engagement groove 332. When the connecting housing 31 rotates around the first engagement area, the second locking tongue 331 can slide into the engagement hole 123 more smoothly.

[0056] Furthermore, such as Figure 7 As shown, the telescopic unit 33 further includes: a pressing groove 333, a slide 335, and an elastic part 334; the pressing groove 333 is formed on the connecting housing 31 and is located on the side of the connecting housing 31 away from the base 11; at least a portion of the second locking tongue 331 extends into the pressing groove 333 along the extending direction of the connecting housing 31, and the pressing groove 333 provides the operator with pressing space and interface; the elastic part 334 is located in the connecting housing 31 along the extending direction of the connecting housing 31, and the two ends of the elastic part 334 are respectively connected to the connecting housing 31 and the second locking tongue 334. The two locking tongues 331 are connected, providing a continuous elastic thrust to the second locking tongue 331, so that it always tends to extend into the locking groove 332 when no external force is applied, ensuring the stability of the second locking tongue 331 engaging with the locking hole 123; the slide 335 is provided in the connecting housing 31 along the extension direction of the connecting housing 31 and is slidably connected with the second locking tongue 331, forming a precise guide for the movement path of the second locking tongue 331, avoiding deflection or jamming during sliding, and ensuring the smoothness and reliability of the telescopic unit 33's operation.

[0057] The extension and retraction of the elastic part 334 causes the second locking tongue 331 to slide along the slide rail 335, thereby causing the second locking tongue 331 to extend into or move away from the locking groove 332. By pressing the second locking tongue 331 to overcome the force of the elastic part 334 and retract along the slide rail 335, the locking state between the second locking tongue 331 and the locking hole 123 can be released, thereby realizing the quick disassembly of the grip assembly 30. This makes the entire telescopic unit 33 have both automatic locking and manual unlocking functions, ensuring stability in the connected state and improving the ease of operation during use.

[0058] Furthermore, such as Figure 3 and Figure 10 As shown, the fixing unit 12 also includes a fixing hole 124; the fixing hole 124 is located on the side of the base 11 and forms a point-to-point direct engagement with the first locking tongue 32. This connection method is simple in structure and precise in positioning, and can quickly achieve initial insertion and positioning during installation, providing a stable rotation fulcrum for the subsequent rotation of the housing 31 around this point. The fixing hole 124 and the fixing groove 121 are spaced apart on the same side of the base 11; the combined state includes: the fixing hole 124 engaging with the first locking tongue 32. In this embodiment, the fixing hole 124 and the first locking tongue 32 are in clearance fit, and the first locking tongue 32 can easily slide into the fixing hole 124, significantly improving the smoothness of assembly and ensuring that the first locking tongue 32 can rotate flexibly within the fixing hole 124.

[0059] In another embodiment, the fixing hole 124 is a stepped hole, and the first locking tongue 32 is L-shaped to cooperate with the stepped hole, so as to achieve dual axial and circumferential limiting of the first locking tongue 32.

[0060] Furthermore, such as Figure 4 and Figure 5 As shown, the belt unit 22 includes a waist belt 221 to restrain the passenger's waist; the waist belt 221 is located on the periphery of the base 11; the restraint state includes: the waist belt 221 is wrapped around one side of the base 11 and fixed to the other side of the base 11, that is, the waist belt 221 forms a closed circumferential restraint structure outside the base 11. This wrapping method can evenly apply the restraint force of the waist belt 221 to the entire circumferential surface of the passenger, thereby achieving circumferential restraint on the passenger's waist area.

[0061] Furthermore, such as Figure 4 and Figure 5As shown, the belt unit 22 also includes a shoulder strap 222 to restrain the passenger's shoulders. The shoulder strap 222 spans above the base 11, further forming a longitudinal constraint beyond the belt unit 22's surrounding perimeter of the base 11, significantly improving the overall fixation capability of the belt unit 22 for the passenger. The shoulder strap 222 and the waist belt 221 work together to achieve a three-dimensional constraint around the passenger's waist and covering the passenger's shoulders, applying restraint forces from multiple directions and effectively improving passenger safety. The two ends of the shoulder strap 222 are connected to the two ends of the waist belt 221, forming a force linkage mechanism. When the connecting housing 31 is impacted and causes the waist belt 221 to move, the shoulder strap 222 tightens simultaneously, further pressing the passenger back to the original position, enhancing passenger safety. In this embodiment, under constraint, the shoulder strap 222 extends diagonally downward from above the passenger's shoulders and bypasses the connecting housing 31 for fixation, achieving better safety restraint for the passenger without affecting the passenger's hand movements.

[0062] Furthermore, such as Figure 4 and Figure 5 As shown, the constraint component 20 also includes multiple guide units 21; the multiple guide units 21 are spaced apart, so that the direction of the belt unit 22 is precisely constrained and optimized. When the belt unit 22 passes around each guide unit 21, it forms a predetermined bypass path, which can prevent the belt unit 22 from twisting, folding or deviating from the preset position during use; some guide units 21 are located above the base 11, and some guide units 21 are located around the base 11; so that the belt unit 22 can be guided in both vertical and horizontal directions at the same time. Specifically, the waist belt part 221 is fixed and guided by the guide units 21 located around the base 11, and the shoulder strap part 222 is fixed and guided by the guide units 21 located above the base 11 and around the base 11; the multiple guide units 21 are sequentially sleeved on the belt unit 22.

[0063] Furthermore, such as Figure 4 and Figure 5 As shown, the guide unit 21 includes a guide frame 211 and a hole 212. The guide frame 211 is located on the periphery of the base 11 and serves as an independent support structure on the periphery of the base 11, providing a reliable mounting base for the belt unit 22. The hole 212 is formed on the guide frame 211, and the guide frame 211 is fitted onto the belt unit 22 through the hole 212. The belt unit 22 is confined to move within the hole, ensuring that the belt unit 22 always travels along a preset path.

[0064] In another embodiment, a first buckle is fixed on a guide frame 211 located around the base 11, and a second buckle is provided around the base 11 to engage with the first buckle. In the constrained state, the engagement of the first buckle and the second buckle fixes the belt unit 22, thereby constraining the passenger. The first buckle and the second buckle can adopt existing locking structures.

[0065] Furthermore, such as Figure 6 , Figure 8 and Figure 9 As shown, the armrest assembly 30 also includes an armrest 34, which provides passengers with a stable and comfortable support area when riding. One end of the armrest 34 is fixed to the connecting housing 31, and the other end extends in a direction away from the connecting housing 31, which is equivalent to extending the support surface outward based on the connecting housing 31. Passengers' arms can rest directly on the armrest 34, avoiding direct contact between the arms and the connecting housing 31 or other rigid structures, which significantly improves the comfort of riding.

[0066] Furthermore, such as Figure 1 and Figure 11 As shown, there are two armrest components 30; the combined state also includes: the two armrest components 30 are respectively located on both sides of the support component 10 and are symmetrically arranged, so that the seat can provide passengers with bilateral symmetrical support function, which significantly improves the suitability and riding experience of the seat; in the combined state, when the passenger moves the belt unit 22, the armrest components 30 located on both sides of the support component 10 will move closer to each other under the action of the belt unit 22, fit the passenger more closely, thereby achieving closer protection for the passenger and improving passenger safety.

[0067] During the installation of the seat, the two armrest components 30 are first placed on both sides of the support component 10, so that the first locking tongue 32 of each armrest component 30 is inserted into the fixing hole 124 on the side of the base 11 and forms a clearance fit. The fixing hole 124 axially limits the first locking tongue 32, thereby establishing the first engagement area. Then, the operator rotates the armrest part 34, so that the connecting housing 31 rotates towards the base 11 with the first engagement area as the fulcrum. At this time, the second locking tongue 33 provided on the connecting housing 31 Because its surface near the base 11 is inclined, it can smoothly slide into the locking hole 123 formed by the fixing groove 121 and the fixing member 122, and abut against the side of the fixing member 122 near the base 11. At the same time, the locking groove 332 and the fixing member 122 abut against each other to form a surface contact support, thereby establishing a second locking area. During this process, the elastic part 334 always applies an elastic pushing force to the second locking tongue 331, so that it keeps extending into the locking groove 332 along the slide 335, ensuring a stable lock. When disassembly is required, the operator only needs to press the part of the second locking tongue 331 that extends into the pressing groove 333, so that it overcomes the force of the elastic part 334 and retracts along the slide 335, thereby disengaging from the locking hole 123, releasing the locking state of the second locking area, and then rotating the connecting housing 31 in the opposite direction to make the first locking tongue 32 exit from the fixing hole 124, thus completing the disassembly. When an external impact causes the passenger to lean forward or when the passenger leans forward voluntarily, at least part of the belt unit 22 leans forward, causing the connecting housing 31 and the second locking tongue 331 to rotate further toward the base 11, making the snap-fit ​​groove 332 abut against the fastener 122 more tightly, reducing the wear of the second locking tongue 331, and making the armrest assembly 30 fit the passenger more closely to provide better safety protection, fundamentally improving the seat's impact resistance and long-term reliability under complex working conditions.

[0068] Those skilled in the art will understand that the above embodiments are specific examples of implementing this disclosure, and in practical applications, various changes can be made in form and detail without departing from the scope of this disclosure.
