[0066] Generally, an automotive seat belt is an important safety device. Its main function is to restrain the occupant when the vehicle collides or brakes suddenly, preventing the occupant from having a secondary collision with hard objects inside the vehicle or being thrown out of the vehicle, thus greatly reducing the risk of injury to the occupant. Based on this, it is a very necessary safety solution to install a seat belt and its matching seat belt buckle on the vehicle. The seat belt buckle is usually installed on the seat or other positions of the vehicle body and fastened with bolts; the installation strength and comfort of common seat belt buckles still need to be improved. How to provide a seat belt buckle with better installation strength and comfort is something that those skilled in the art need to consider.

[0067] Correspondingly, the present application provides a seat belt buckle, a fixed connection device, and a vehicle. The seat belt buckle is used to connect with a tongue, and the seat belt buckle includes a buckle body and a connecting plate; the buckle body is used to connect the tongue; the connecting plate includes a connecting portion and a fixing portion, the connecting portion is connected to the buckle body, and the fixing portion is used to assemble the seat belt buckle; the connecting portion and the fixing portion are bent and connected, and the connecting portion is laterally twisted relative to the fixing portion at the connection between the two, so that the connecting portion and the fixing portion are inclined. The fixed connection device includes a connection body and a seat belt buckle, and the connection body is connected to the seat belt buckle; the connection body is provided with a through-hole, a section of the fixing portion is received in the through-hole, and the inner wall of the connection body surrounding the through-hole is configured to detachably abut against the fixing portion. The vehicle includes a main body portion, and a seat belt buckle or a fixed connection device; the seat belt buckle or the fixed connection device is installed on the main body portion.

[0068] Furthermore, the seat belt buckle can be connected to a tongue through the buckle body, the connecting portion is connected to the buckle body, and the fixing portion is connected to the connecting portion; by fixing the fixing portion and / or the connecting portion, the fixing of the buckle body and the tongue can be achieved. The connecting portion and the fixing portion are bent and connected, and the connecting portion and the fixing portion can extend in different directions respectively, so that the fixing portion can be configured to have sufficient length to ensure the installation strength of the seat belt buckle; at the same time, the connecting portion and the fixing portion are not arranged in the same direction, which can help shorten the protruding height of the connecting portion connecting the seat belt buckle, and further reduce the protruding height of the seat belt buckle, and try to avoid the seat belt buckle from touching or abutting against the occupant, thus improving comfort. The fixing portion of the seat belt buckle passes through the through-hole and is partially received in the through-hole, and the inner wall of the connection body surrounding the through-hole is configured to be located outside the fixing portion. The fixing portion can detachably abut against the inner wall of the connection body surrounding the through-hole. When the fixing portion abuts against the inner wall of the connection body surrounding the through-hole, the connection body can provide a reverse support for the fixing portion, further enhancing the installation strength of the seat belt buckle. The vehicle is equipped with a seat belt buckle or a fixed connection device, and the seat belt buckle or the fixed connection device can be arranged corresponding to the vehicle seat, for improving the installation strength of the seat belt buckle and the riding comfort of the occupant.

[0069] Those skilled in the art can understand that a "seat belt buckle" refers to a fixed connection structure capable of connecting a tongue, which can connect a restraint structure for restraining an occupant (such as a seat belt connected with a tongue) to an anchoring structure for providing support (such as a vehicle frame or a seat skeleton) to fix the occupant.

[0070] Those skilled in the art can understand that "bending connection" means that two connected parts extend along at least one direction respectively at their connection, and these at least two directions are not parallel.

[0071] Those skilled in the art can understand that "tilted setting" means that two parts are neither parallel nor perpendicular.

[0072] Those skilled in the art can understand that "opening" refers to an open structure having a certain thickness and openings in at least two directions.

[0073] The following content will describe exemplary embodiments in conjunction with the accompanying drawings. It should be noted that the components depicted in the reference drawings are not necessarily shown to scale; and the same or similar components will be given the same or similar reference numerals or similar technical terms.

[0074] The following will refer to the accompanying drawings to further describe in detail the specific embodiments of the present application.

[0075] As Figures 1 to 4 shown, an embodiment of the present application provides a seat belt buckle 10. The seat belt buckle 10 is used to connect with a tongue (not shown in the figure). The seat belt buckle 10 includes a buckle body 11 and a connecting plate 12. The buckle body 11 is used to connect the tongue; the connecting plate 12 includes a connecting portion 121 and a fixing portion 122. The connecting portion 121 is connected to the buckle body 11, and the fixing portion 122 is used to assemble the seat belt buckle 10; wherein, the connecting portion 121 and the fixing portion 122 are bent-connected, and the connecting portion 121 is laterally twisted at the connection with the fixing portion 122, so that the connecting portion 121 and the fixing portion 122 are tilted.

[0076] It should be explained that the tongue is connected to the buckle body 11. The mutual connection manner between the tongue and the buckle body 11 and the specific shape structure of the tongue can adopt known and feasible structures, which will not be elaborated here.

[0077] It can be understood that the seat belt buckle 10 can be connected to the locking tongue via the body 11, the connecting portion 121 is connected to the locking body 11, and the fixing portion 122 is connected to the connecting portion 121; by fixing the fixing portion 122 and / or the connecting portion 121, the locking body 11 and the locking tongue can be fixed. The connecting portion 121 and the fixing portion 122 are bent and connected, and the connecting portion 121 and the fixing portion 122 can be extended in different directions respectively, so that the fixing portion 122 can be constructed to have a sufficient length, thereby ensuring the installation strength of the seat belt buckle 10; at the same time, the connecting portion 121 and the fixing portion 122 are not arranged in the same direction, which can help shorten the protruding height of the connecting portion 121, thereby reducing the protruding height of the seat belt buckle 10, and avoiding the seat belt buckle 10 from touching or abutting against the occupant as much as possible, thereby improving comfort.

[0078] In one embodiment, the connecting portion 121 is extended along a first extension direction L1, the fixing portion 122 is extended along a second extension direction L2, the bending boundary between the connecting portion 121 and the fixing portion 122 is extended along a third extension direction L3, and the plane defined by the second extension direction L2 and the third extension direction L3 intersects with the first extension direction L1 and is not perpendicular.

[0079] In this embodiment, the example that the connecting portion 121 and the fixing portion 122 are both roughly plate-shaped is used for demonstration. The first extension direction L1 roughly corresponds to the length direction of the connecting portion 121, the second extension direction L2 roughly corresponds to the length direction of the fixing portion 122, and the third extension direction L3 roughly corresponds to the width direction of the fixing portion 122. At the same time, the thickness direction of the fixing portion 122 roughly corresponds to the fourth extension direction L4, the third extension direction L3 is perpendicular to the fourth extension direction L4, and the first extension direction L1 can be located between the third extension direction L3 and the fourth extension direction L4, and is set at an angle with the third extension direction L3 and the fourth extension direction L4 respectively. The angle between the first extension direction L1 and the fourth extension direction L4 is the forward tilt angle θ, and the angle range of the forward tilt angle θ is 10° to 20°, and can specifically be 11°, 12°, 13°, 14°, 15°, 16°, 17°, 18°, and 19°. It needs to be explained that “the connecting portion 121 is laterally twisted at the connection between the connecting portion 121 and the fixing portion 122” means that the connecting portion 121 and the fixing portion 122 are bent but not perpendicular along the extension plane of the fixing portion 122, and “lateral twisting setting” indicates the relative position relationship between the connecting portion 121 and the fixing portion 122, but does not limit the connecting portion 121 and the fixing portion 122 to be formed by a process of twisting the two.

[0080] In other embodiments, the connecting portion 121 and the fixing portion 122 may also be other irregular shapes, such as hollow shapes or branches extending in various directions, etc. The main body of the fixing portion 122 can be fixedly installed along the fourth extension direction L4, and the connecting portion 121 is fixed by connecting with the fixing portion 122. The main body of the connecting portion 121 extends along the first extension direction L1, so that the lock body 11 is convex and inclined compared to the fixing portion 122 along the first extension direction L1.

[0081] It is understandable that when the seat belt buckle 10 is assembled and in a usable state, the restraining member (such as the belt body of the seat belt) connected to the locking tongue is usually arranged obliquely around the front chest of the human body, and the seat belt buckle 10 is usually arranged behind the passenger's sitting position, and the passenger usually inserts the locking tongue into the buckle in an oblique downward direction. The connecting portion 121 and the buckle body 11 are arranged obliquely along the forward inclination angle θ, so that the insertion and extraction process of the locking tongue is more ergonomic and more convenient to operate. In some embodiments, the locking tongue is inserted into or extracted from the buckle body 11 along the first extension direction L1.

[0082] It can be understood that the seat belt buckle 10 is usually arranged relatively to the rear of the passenger's seat position and tilted toward one side along the first extension direction L1. When the seat belt buckle 10 is mounted on the fixed connection device 1 or the vehicle 2, the buckle body 11 tilts toward the front of the vehicle (or understood as the side where the passenger sits). The height of the end of the seat belt buckle 10 close to the passenger along the fourth extension direction L4 is reduced due to the tilt, making it less likely to come into direct contact with the passenger; although the height of the other end of the seat belt buckle 10 away from the passenger along the fourth extension direction L4 will be increased due to the tilt, this end is far away from the user, and the probability of it being touched by the passenger is relatively low; therefore, the inclined seat belt buckle 10 is not likely to come into direct contact with the passenger as a whole, and has higher comfort.

[0083] In one embodiment, the lock body 11 is connected to an end of the connecting portion 121 away from the fixing portion 122 .

[0084] In this embodiment, the lock body 11 and the fixing part 122 are connected by the connecting part 121, and the lock body 11 is spaced apart from the fixing part 122 by the connecting part 121. After the seat belt buckle 10 is installed, the lock body 11 can have a convex posture, which is convenient for the lock body 11 to be connected with the locking tongue.

[0085] In one embodiment, the lock body 11 is provided with a first mounting hole 111 and a second mounting hole 112. The first mounting hole 111 is used to allow the end of the connecting portion 121 away from the fixing portion 122 to extend into the lock body 11 and be fixedly connected to the lock body 11, and the second mounting hole 112 is used to allow the locking tongue to extend into the lock body 11 and be detachably connected to the lock body 11.

[0086] In this embodiment, the first mounting hole 111 extends along the first extension direction L1 and is arranged corresponding to the extension direction of the connecting plate 12 to avoid hard contact between the connecting plate 12 and the housing 110 of the buckle body 11. Similarly, the second mounting hole 112 extends along the first extension direction L1 and is arranged corresponding to the convenient insertion direction of the lock tongue (the direction that is convenient for the occupant to insert the lock tongue from the ergonomic perspective) and / or the force application direction (for example, the direction in which the lock tongue has a separation tendency from the buckle body 11 due to being pulled by the seat belt) to avoid hard contact between the lock tongue and the housing 110 of the buckle body 11.

[0087] It can be understood that when the seat belt buckle 10 is assembled and in a usable state, making the connecting portion 121 and the buckle body 11 inclined along the front inclination angle θ can reduce the probability of hard contact between the lock tongue and / or the connecting portion 121 and the housing 110 of the buckle body 11. Specifically, the opening size of the first mounting hole 111 is slightly larger than the width of the connecting portion 121, and the opening size of the second mounting hole 112 is slightly larger than the width of the lock tongue; if the connecting portion 121 and the buckle body 11 are not inclined along the front inclination angle θ but only protrude along the fourth extension direction L4, then in the event of an accidental collision, the angle between the lock tongue and the buckle body 11 is not corresponding, and the lock tongue will abut against the edge of the buckle body 11 and have hard contact with it, which may cause the housing 110 of the buckle body 11 to be damaged, and further cause the seat belt buckle 10 to be accidentally unlocked or unable to be unlocked; similarly, the lock tongue abutting against the edge of the buckle body 11 may also drive the buckle body 11 to deflect beyond the limit relative to the connecting portion 121, resulting in the connecting portion 121 abutting against the edge of the buckle body 11 and having hard contact with it, which may also cause the housing 110 of the buckle body 11 to be damaged, and further cause the seat belt buckle 10 to be accidentally unlocked or unable to be unlocked; however, in the seat belt buckle 10 of the present application, the connecting portion 121 and the buckle body 11 are inclined along the front inclination angle θ, the lock tongue generally has a separation tendency along the first extension direction L1 relative to the seat belt buckle 10, the first mounting hole 111 and the second mounting hole 112 and the connecting portion 121 have an arrangement direction corresponding to the first extension direction L1, and the lock tongue is not likely to abut against or have hard contact with the housing 110 of the buckle body 11, thereby reducing the possibility of the lock tongue directly damaging the buckle body 11 or indirectly damaging it by driving the deflection of the buckle body 11, and improving the safety of the buckle body 11.

[0088] In one embodiment, the connecting portion 121 and the fixing portion 122 are integrally connected to form a force-bearing whole.

[0089] In this embodiment, the connecting plate 12 is taken as an example of an integrally formed sheet metal, the connecting portion 121 and the fixing portion 122 are bent at the connection point so that the two have different extension directions, and the connecting portion 121 and the fixing portion 122 are integrally connected and form a force-bearing whole. The connecting portion 121 and the fixing portion 122 have a good connection strength, and by fixing the connecting portion 121 and / or the fixing portion 122, the lock body 11 can be better fixed.

[0090] In other embodiments, the connecting portion 121 and the fixing portion 122 may also be non-integrally formed, and the connecting portion 121 and the fixing portion 122 may be fixed by feasible installation methods such as welding, riveting, and locking, which can also better fix the lock body 11.

[0091] In one embodiment, the connecting portion 121 includes a first end portion 1211 facing away from the fixing portion 122, and a plurality of first connecting structures 1212 are provided on the first end portion 1211, and the first connecting structures 1212 can be used to connect the connecting portion 121 to the lock body 11. The fixing portion 122 includes a second end portion 1221 facing away from the connecting portion 121, and a second connecting structure 1222 is provided on the second end portion 1221, and the second connecting structure 1222 can be used to assemble the fixing portion 122. The second end portion 1221 is also provided with a protruding positioning end 1223 on the side facing away from the connecting portion 121, and the positioning end 1223 can be used to position the fixing portion 122.

[0092] In this embodiment, the first connection structure 1212 and the second connection structure 1222 are shown as through-type openings, which can be used to cooperate with the fixing member 16 of the structure of the cam, bolt, rivet, etc. In other embodiments, the first connection structure 1212 and the second connection structure 1222 can also have other connection forms, which are not repeated here.

[0093] Further integration Figure 5 As shown, in other embodiments, the lock body 11 may further include a sensor 123. One end of the sensor 123 extends into the lock body 11, and is used to sense the plug-in state of the lock tongue and the lock body 11 and generate a corresponding sensing signal. The other end of the sensor 123 extends out of the lock body 11 and can be electrically connected with other electronic components to derive the sensing signal. It can be understood that the sensor 123 can use a known and feasible structure, and its specific working method, connection method, etc. are not repeated.

[0094] Further integration Figure 5 As shown, in other embodiments, the lock body 11 may not be provided with the positioning end 1223, and the installation of the fixing portion 122 may also be achieved.

[0095] Further integrationFigures 6 to 8 As shown in the figure, an embodiment of the present application further provides a fixed connection device 1, which includes a connection body 15 and a seat belt buckle 10 as described in any one of the foregoing embodiments. The connection body 15 is connected to the seat belt buckle 10. Among them, the connection body 15 is provided with a through hole 150, and a section of the fixing portion 122 is received in the through hole 150. The inner wall 153 of the connection body 15 surrounding the through hole 150 is configured to abut against the fixing portion 122 in a separable manner.

[0096] It can be understood that the fixing portion 122 of the seat belt buckle 10 passes through the through hole 150 and is partially received in the through hole 150. The inner wall 153 of the connection body 15 surrounding the through hole 150 is configured to be located outside the fixing portion 122. The fixing portion 122 can abut against the inner wall 153 of the through hole 150 surrounded by the connection body 15 in a separable manner; when the fixing portion 122 abuts against the inner wall 153, the connection body 15 can provide a reverse support for the fixing portion 122, further enhancing the installation strength of the seat belt buckle 10.

[0097] In this embodiment, the connection body 15 is taken as an example of a seat frame for display. In other embodiments, the connection body 15 can also be a vehicle frame, or the connection body 15 can also be other fixed structures on the vehicle.

[0098] To more clearly show the technical solution of the present application, the present application uses a three-dimensional coordinate system composed of a first direction X, a second direction Y, and a third direction Z as a spatial reference to display the seat belt buckle 10 and the fixed connection device 1 provided in the embodiments of the present application. Among them, the first direction X, the second direction Y, and the third direction Z are the three-axis directions of the Cartesian coordinate system, and the first direction X, the second direction Y, and the third direction Z are perpendicular to each other; specifically, the first direction X can correspond to the length direction of a common vehicle (or the direction facing the front of a common vehicle), the second direction Y can correspond to the width direction of a common vehicle (or the direction facing the side of a common vehicle), and the third direction Z can correspond to the height direction of a common vehicle (or the direction facing the bottom of a common vehicle). The first extension direction L1, the second extension direction L2, the third extension direction L3, and the fourth extension direction L4 can respectively have an intersecting or parallel relationship with any one of the first direction X, the second direction Y, and the third direction Z; for example, in this embodiment, the second extension direction L2 is parallel to the second direction Y, the third extension direction L3 is parallel to the first direction X, and the fourth extension direction L4 is parallel to the third direction Z.

[0099] In one embodiment, the connecting portion 121 is torsionally inclined with respect to the fixing portion 122 along the first direction X. The fixing portion 122 is disposed through the opening 150 along the second direction Y. The connecting portion 121 protrudes with respect to the fixing portion 122 along the third direction Z. The buckle body 11 is disposed at one end of the connecting portion 121 along the third direction Z away from the fixing portion 122. At least a part of the inner wall 153 of the connecting body 15 surrounding the opening 150 overlaps with the projection of the fixing portion 122 along the first direction X, and / or at least a part of the inner wall 153 of the connecting body 15 surrounding the opening 150 overlaps with the projection of the fixing portion 122 along the third direction Z.

[0100] In this embodiment, the fixing portion 122 is disposed through the opening 150 along the second direction Y. The part of the fixing portion 122 away from the connecting portion 121 extends into the inner side of the connecting body 15. The second end portion 1221 of the fixing portion 122 is locked to the connecting body 15 along the third direction Z by the fixing member 16. One end of the fixing portion 122 along the second direction Y away from the second end portion 1221 passes through the opening 150 and extends to the outside of the connecting body 15, and is bent and connected to the connecting portion 121. The connecting portion 121 further protrudes along the third direction Z toward the side away from the fixing portion 122. At the same time, the connecting portion 121 is inclined with respect to the third direction Z. The buckle body 11 is connected to one end of the connecting portion 121 away from the fixing portion 122 and is disposed outside the connecting body 15.

[0101] It can be understood that the fixing portion 122 is disposed along the second direction Y, and the buckle body 11 extends in the third direction Z. The fixing portion 122 disposed along the second direction Y has a relatively large length, which can make the connecting plate 12 easier to assemble and / or increase the connection strength. At the same time, the connecting portion 121 protruding in the third direction Z has a relatively small length, which can reduce the protruding height of the buckle body 11 in the third direction Z, avoid excessive protrusion of the buckle body 11, and avoid the buckle body 11 from abutting against the occupant and causing discomfort to the occupant. Furthermore, the second end portion 1221 of the fixing portion 122 is locked along the third direction Z by the fixing member 16. After the seat belt buckle 10 is pulled by an external force, the force acting on the second end portion 1221 and the fixing member 16 is no longer only the shear force along the radial direction of the fixing member 16, but may also include the abutting force along the third direction Z, so that the seat belt buckle 10 and the fixed connection device 1 of the present application can have higher fixing strength.

[0102] In this embodiment, the opening 150 is formed through the connection body 15 along the second direction Y. After the fixing portion 122 passes through the opening 150, a section of the fixing portion 122 still remains inside the opening 150. The inner wall 153 of the connection body 15 surrounding the opening 150 is correspondingly arranged around the fixing portion 122, so that the projections of the inner wall 153 of the connection body 15 surrounding the opening 150 and the fixing portion 122 along the first direction X and the third direction Z at least partially overlap. That is, when the fixing portion 122 is displaced along the first direction X or the third direction Z, the fixing portion 122 can abut against the corresponding inner wall 153 along the first direction X and / or the third direction Z, so that the connection body 15 provides a reverse support for the fixing portion 122, especially can provide a reverse supporting force for the fixing portion 122 along the third direction Z.

[0103] It can be understood that when the seat belt buckle 10 is pulled by an external force, the fixing portion 122 can abut against the inner wall 153 of the connection body 15 surrounding the opening 150, providing additional support for the seat belt buckle 10, so that the seat belt buckle 10 and the fixed connection device 1 of the present application can have higher fixing strength.

[0104] In one embodiment, the opening 150 is formed in the side plate 151 of the connection body 15. The fixing portion 122 passes through the opening 150, and the second end portion 1221 is connected to the connection body 15. The connection body 15 includes a side plate 151, the opening 150 is formed in the side plate 151, and the connection portion 121 and the second end portion 1221 are respectively arranged on two opposite sides of the side plate 151.

[0105] In one embodiment, the connection body 15 includes a bottom plate 152. The bottom plate 152 is arranged along the third direction Z on the side of the fixing portion 122 away from the buckle body 11, and the fixing portion 122 is connected to the bottom plate 152.

[0106] In this embodiment, the connection body 15 is a sheet metal bracket with a bent structure, which has a side plate 151 and a bottom plate 152 connected by bending. The opening 150 is formed corresponding to the connection position of the side plate 151 and the bottom plate 152. The thickness direction of the side plate 151 generally corresponds to the second direction Y. The bottom plate 152 is substantially perpendicular to the side plate 151. The connection portion 121 and the second end portion 1221 are respectively arranged on two opposite sides of the side plate 151 along the second direction Y.

[0107] In one embodiment, a positioning buckle 1521 may be further provided at the end of the bottom plate 152 away from the side plate 151. The positioning end 1223 provided on the fixing portion 122 can extend into the positioning buckle 1521, which is used to position or lock the connecting plate 12 during the installation process, avoid the connecting plate 12 from deviating during the installation process, and improve the assembly convenience when the seat belt buckle 10 is installed on the connection body 15.

[0108] Further combined with Figures 9 to 11As shown, in other embodiments, the connecting body 15 may further include a reinforcing plate 154, and the reinforcing plate 154 is connected to the side plate 151. The reinforcing plate 154 is disposed on a side of the fixing portion 122 close to the lock body 11 along the third direction Z. The projection of the fixing portion 122 along the third direction Z at least partially overlaps with the projection of the reinforcing plate 154 along the third direction Z.

[0109] Combination Figure 9 As shown, in another embodiment, the fixing portion 122 can abut against the reinforcing plate 154 along the third direction Z, and the reinforcing plate 154 extends along the second direction Y to lock the fixing portion 122 with the reinforcing plate 154. The area where the reinforcing plate 154 abuts against the fixing portion 122 along the third direction Z is larger than the area where the inner wall 153 of the connecting body 15 surrounding the opening 150 abuts against the fixing portion 122 along the third direction Z, and the contact area between the fixing portion 122 and the connecting body 15 along the third direction Z is larger, so as to obtain better support along the third direction Z.

[0110] Combination Figure 10 As shown, in another embodiment, the fixing portion 122 can abut against the reinforcing plate 154 along the third direction Z, so as to provide support for the fixing portion 122 along the third direction Z. The reinforcing plate 154 is staggered with the fixing member 16 along the second direction Y, and the fixing portion 122 and the bottom plate 152 are locked by the fixing member 16. The reinforcing plate 154 can provide additional support for the fixing portion 122 along the third direction Z, and at the same time connect the fixing portion 122 with the bottom plate 152, so that the seat belt buckle 10 and the fixing connection device 1 have good assembly convenience.

[0111] Combination Figure 11 As shown, in yet another embodiment, the fixing portion 122 is clamped between the reinforcing plate 154 and the bottom plate 152 along the third direction Z, and the fixing portion 122 is respectively connected to the reinforcing plate 154 and the bottom plate 152 through different fixing members 16, so as to further enhance the strength of the seat belt buckle 10 and the fixing connection device 1; at the same time, a hollow area 1520 is provided on the bottom plate 152 corresponding to at least a portion of the reinforcing plate 154, and the hollow area 1520 can be used to expose the fixing members 16 connecting the fixing portion 122 and the reinforcing plate 154 for easy installation.

[0112] Further integration Figure 12 As shown, an embodiment of the present application further provides a vehicle 2, which includes a main body 21, and a seat belt buckle 10 as in any one of the aforementioned embodiments, or a fixing connection device 1 as in any one of the aforementioned embodiments; the seat belt buckle 10 or the fixing connection device 1 is installed on the main body 21.

[0113] It can be understood that the vehicle 2 is equipped with a seat belt buckle 10 or a fixed connection device 1. The seat belt buckle 10 or the fixed connection device 1 can be arranged corresponding to the seats (especially the rear seats) of the vehicle 2, so as to improve the installation strength of the seat belt buckle 10 and the riding comfort of the occupants in the seat riding positions.
