Description

Technical Field

[0001] The present invention relates to a seat belt adjustment mechanism, a baby stroller, a child seat, a high chair, and a bicycle seat.

Background Art

[0002] One specific form of a seat belt is a five-point seat belt. The five-point seat belt includes two shoulder belts, two crotch / waist belts, and a central buckle located between both feet. The five-point seat belt has a total of five-point restraints at one point under the crotch, two points on both sides of the waist, and two points above the shoulders, covering the main parts of the human body. Therefore, when a strong impact occurs, the five-point seat belt can relieve the same pressure over a larger area of the human body, thereby reducing the pressure at a certain point and reducing the damage to the human body caused by these impacts.

[0003] Therefore, considering that the development of the human body, such as the skeletal tissue of children, is immature, in the design of seats for children to ride, a five-point seat belt is adopted to disperse and relieve the pressure caused by impacts on each part of the body, thereby reducing the damage to the child's body caused by the impact during an accident.

[0004] However, in the conventional seat belt adjustment structure, when adjusting the tightness of the shoulder belt or the waist belt, it is necessary to adjust each shoulder belt or waist belt individually, so the operation is complicated and time-consuming. In the conventional seat belt, the shoulder belt and the waist belt are usually installed separately, so they need to be adjusted individually, which is not only complicated and time-consuming, but also leaves long tails at the shoulder belt and the waist belt, affecting the riding experience.

[0005] Therefore, in view of the problems of the prior art, developing an improved seat belt adjustment mechanism has become a technical problem to be solved by those skilled in the art.

[Modes for carrying out the invention]

[0022] Hereinafter, the technical means in embodiments of the present invention will be clearly and completely described with reference to the drawings of the embodiments. Obviously, the embodiments described are only some, not all, embodiments of the present invention. The following description of at least one exemplary embodiment is for practical purposes only and does not limit the present invention or its application or use. All other embodiments obtained by those skilled in the art without creative work based on embodiments of the present invention are within the scope of the protection of the present invention.

Also, the terms "includes," "contains," or any other variation thereof are intended to cover non-exclusive inclusion, and a process, method, article, or device containing a set of elements includes not only those elements but also other elements not explicitly listed, or elements specific to such a process, method, article, or device. Unless there are further restrictions, an element limited by the phrase "one includes" does not preclude the presence of other identical elements in a process, method, article, or device containing the element.

[0024] As shown in Figures 1 to 5, this embodiment discloses a seat belt adjustment mechanism including a first backrest portion 1, a second backrest portion 2, a connecting portion 3, a first locking device 4, a second locking device 5, a first seat belt 6, a second seat belt 7, a first elastic connecting member 8, a second elastic connecting member 9, a first extension cord 10, a second extension cord 1011, and an operating stay 1012.

[0025] The first backrest portion 1 and the second backrest portion 2 may be tubular in shape, or they may be rod-shaped, plate-shaped, or have other shapes.

[0026] The connecting part 3 connects the first backrest part 1 and the second backrest part 2. The connecting part 3 may also be a tubular structure, a rod-shaped, plate-shaped, or other shape. The three components, the first backrest part 1, the second backrest part 2, and the connecting part 3, may be a single integrated structure, a separate structure, or three parts of a single overall structure. If the three components are a single integrated structure, the overall strength of the structure can be enhanced, and if the three components are a separate structure, it is convenient for transportation and storage.

[0027] The first locking device 4 is attached to the connecting part 3 or the first backrest part 1.

[0028] The second locking device 5 is attached to the connecting part 3 or the second backrest part 2.

[0029] The first seat belt 6 includes a fixed end and a movable end. The first seat belt 6 is provided on the first locking device 4 so as to pass through the first locking device 4. The first seat belt 6 is locked or unlocked by the first locking device 4. If the first locking device 4 is not operated, the first seat belt 6 is locked by the first locking device 4 and cannot be moved. Only when an unlock operation is performed on the first locking device 4 does the first seat belt 6 become unlocked by the first locking device 4 and can be moved.

[0030] The second seat belt 7 includes a fixed end and a movable end. The second seat belt 7 is provided on the second locking device 5 so as to pass through the second locking device 5. The second seat belt 7 is locked or unlocked by the second locking device 5. If the second locking device 5 is not operated, the second seat belt 7 is locked by the second locking device 5 and cannot be moved. Only when an unlock operation is performed on the second locking device 5 does the second seat belt 7 become unlocked by the second locking device 5 and can be moved.

[0031] The first elastic connecting member 8 is connected to the first backrest portion 1, and the first elastic connecting member 8 is provided with a first passing portion 81.

[0032] The second elastic connecting member 9 is connected to the second backrest portion 2, and the second elastic connecting member 9 is provided with a second passage portion 91.

[0033] The first extension strap 10 has one end connected to the first backrest 1 and the other end passing through the first passage 81 to connect to the movable end of the first seat belt 6 or another nearby location. The first extension strap 10 is folded back after passing through the passage 81. The first extension strap 10 is pulled by the first elastic connecting member 8. The first extension strap 10 may be kept taut by the first elastic connecting member 8. That is, the first elastic connecting member 8 is taut by default and always applies tensile force to the first extension strap 10, thereby moving the movable end of the first seat belt 6 toward the first elastic connecting member 8.

[0034] The second extension strap 1011 has one end connected to the second backrest 2 and the other end passing through the second passage 91 to connect to the movable end of the second seat belt 7 or another nearby location. The second extension strap 1011 is folded back after passing through the passage 91. The second extension strap 1011 is pulled by the second elastic connecting member 9. The second extension strap 1011 may be kept taut by the second elastic connecting member 9. That is, the second elastic connecting member 9 is taut by default and always applies tensile force to the second extension strap 1011, thereby moving the movable end of the second seat belt 7 toward the second elastic connecting member 9.

[0035] The operating stay 1012 connects the first locking device 4 and the second locking device 5. The operating stay 1012 can unlock the first locking device 4 and the second locking device 5 simultaneously.

[0036] In this embodiment, according to the above structure, the operating stay 1012 can simultaneously unlock the first locking device 4 and the second locking device 5. The first seat belt 6 is unlocked by the first locking device 4, and the movable end of the first seat belt 6 is pulled by the first elastic connecting member 8 and automatically moves toward the first elastic connecting member 8, thereby fastening the first seat belt 6. At the same time, the second seat belt 7 is unlocked by the second locking device 5, and the movable end of the second seat belt 7 is pulled by the second elastic connecting member 9 and automatically moves toward the second elastic connecting member 9, thereby fastening the second seat belt 7.

[0037] Therefore, when a user needs to adjust the tightness of the two seat belts of the seat belt adjustment mechanism according to this embodiment, they do not need to adjust each seat belt separately, making the operation simple and time-consuming. Also, because the required adjustment amount for the seat belts is relatively large, if the first elastic connecting member 8 is directly connected to the first extension cord 10 and the second elastic connecting member 9 is directly connected to the second extension cord 1011, it is necessary to arrange the first elastic connecting member 8 and the second elastic connecting member 9, which have a large volume. Therefore, in this embodiment, by providing the first extension cord 10 and the second extension cord 1011 in cooperation with other corresponding structures, the first elastic connecting member 8 and the second elastic connecting member 9 can be miniaturized, reducing not only weight but also cost.

[0038] Furthermore, in this embodiment, the tensile length of the first elastic connecting member 8 is smaller than the travel length of the first seat belt 6. Preferably, the ratio of the tensile length of the first elastic connecting member 8 to the travel length of the first seat belt 6 is 1:2, that is, for every 1 unit change in the length of the first elastic connecting member 8, the first seat belt 6 is pulled and moves a distance of 2 units. Similarly, the tensile length of the second elastic connecting member 9 is smaller than the travel length of the second seat belt 7. Preferably, the ratio of the tensile length of the second elastic connecting member 9 to the travel length of the second seat belt 7 is 1:2, that is, for every 1 unit change in the length of the second elastic connecting member 9, the second seat belt 7 is pulled and moves a distance of 2 units.

[0039] In this embodiment, by setting the tensile lengths of the first elastic connecting member 8 and the second elastic connecting member 9 to be smaller than the travel lengths of the first seat belt 6 and the second seat belt 7, respectively, the necessary force can be effectively provided when the elastic connecting members are pulled, allowing the seat belts to be fastened quickly.

[0040] Furthermore, in this embodiment, the first locking device 4 includes a first adjustment base 41, a first locking member 42, and a first elastic member 43.

[0041] The first adjustment base 41 is attached to the connecting member 3 by screwing it in place.

[0042] The first locking member 42 is rotatably attached to the first adjustment base 41 by rivets.

[0043] The first elastic member 43 is attached to the connection between the first locking member 42 and the first adjustment base 41. The first elastic member 43 is positioned such that the first locking member 42 approaches the side wall of the first adjustment base 41 in the counterclockwise direction in Figure 2, pressing against the first seat belt 6, and the frictional force between the first locking member 42 and the first seat belt 6 is greater than the tensile force of the first elastic connecting member 8. This ensures that the first seat belt 6 cannot slide freely downward (towards the first elastic connecting member 8). In this embodiment, the first elastic member 43 is a torsion spring, but is not limited thereto.

[0044] The second locking device 5 includes a second adjustment base, a second locking member, and a second elastic member.

[0045] The second adjustment base is attached to the connecting member 3 by screwing it in, maintaining a constant distance from the first adjustment base 41.

[0046] The second locking member is rotatably attached to the second adjustment base by rivets.

[0047] The second elastic member is attached to the connection between the second locking member and the second adjustment base. The second elastic member is positioned such that the second locking member approaches the side wall of the second adjustment base and presses against the second seat belt 7, and the frictional force between the second locking member and the second seat belt 7 is greater than the tensile force of the second elastic connecting member 9, thereby ensuring that the second seat belt 7 cannot slide freely downward (towards the second elastic connecting member 9). In this embodiment, the second elastic member is a torsion spring, but is not limited thereto.

[0048] The operating stay 1012 has one end connected to the first locking member 42 and the other end connected to the second locking member, and the operating stay 1012 rotates the first locking member 42 and the second locking member simultaneously.

[0049] In this embodiment, taking the first locking device 4 as an example, when the operating rod is pulled up, the operating rod rotates the first locking member 42 clockwise, and when the gap between the first locking member 42 and the side wall of the adjustment base becomes larger than the thickness of the first seat belt 6, the first seat belt 6 can move freely, thereby realizing the function of tightening or loosening the first seat belt 6. The principle of the second locking device 5 is similar. As shown in Figure 4, (1) Seat belt tightening operation: When the operating stay 1012 is pulled up in the direction of arrow A, the first seat belt 6 and the second seat belt 7 are automatically tightened by being pulled by the corresponding elastic connecting members. (2) Seat belt loosening operation: Pull the operating stay 1012 in the direction of arrow A and pull the first seat belt 6 and the second seat belt 7 in the direction of B.

[0050] The design of the first locking member 42 and the second locking member, combined with the arrangement of the elastic member, improves stable structural support and ensures the reliability of seat belt use under various conditions. The first locking device 4 and the second locking device 5 in this embodiment are simple in structure, stable, resistant to damage, and can save costs on seat belt adjustment mechanisms and extend their service life.

[0051] Furthermore, in this embodiment, the first locking member 42 is provided with a plurality of pointed teeth on the side closer to the side wall of the first adjustment base 41. The second locking member is provided with a plurality of pointed teeth on the side closer to the side wall of the second adjustment base.

[0052] In the seat belt adjustment mechanism of this embodiment, the first locking member 42 and the second locking member are provided with multiple pointed teeth on the side closest to the side wall of their respective adjustment bases. The presence of the pointed teeth provides additional locking points, making the seat belt more secure in the locking device and improving the safety of the seat belt system. Because the pointed teeth can work precisely with the corresponding structure on the seat belt, seat belt adjustment becomes more precise, ensuring that the position and tension of the seat belt meet the passenger's needs. In the event of emergency braking or a collision, the pointed teeth can prevent the seat belt from sliding in the locking member, ensuring that the seat belt can provide sufficient restraint in critical moments.

[0053] Furthermore, as shown in Figure 5, in this embodiment, the first seat belt 6 includes a first shoulder belt portion 61 and a first waist belt portion 62, and the first shoulder belt portion 61 and the first waist belt portion 62 are integrally structured. The second seat belt 7 includes a second shoulder belt portion 71 and a second waist belt portion 72, and the second shoulder belt portion 71 and the second waist belt portion 72 are integrally structured.

[0054] In other words, in this embodiment, the first shoulder belt portion 61 and the first waist belt portion 62 constitute the first seat belt 6, and the second shoulder belt portion 71 and the second waist belt portion 72 constitute the second seat belt 7. Therefore, both the shoulder belt portion and the waist belt portion can be adjusted simultaneously, making operation simple and convenient. Furthermore, since there are no excess exposed parts in the first seat belt 6 and the second seat belt 7, they do not get in the way of passengers and can provide a more comfortable ride.

[0055] Furthermore, in this embodiment, the first elastic connecting member 8 is a first tension spring. The first tension spring has one end connected to the first backrest portion 1 and a first through portion 81 at the other end. The first through portion 81 is an annular end portion. The second elastic connecting member 9 is a second tension spring. The second tension spring has one end connected to the second backrest portion 2 and a second through portion 91 at the other end. The second through portion 91 is an annular end portion.

[0056] In this embodiment, by using a tension spring as an elastic connecting member, the seat belt adjustment mechanism becomes more compact overall, reducing the space it occupies. Furthermore, because the tension spring can act quickly, the seat belt can be fastened quickly. A standardized tension spring assembly reduces production costs and facilitates large-scale production.

[0057] This embodiment further discloses the high chair shown in Figure 6, the car seat (child seat) shown in Figure 7, the stroller shown in Figure 8, and the bicycle seat shown in Figure 9, all of which include the seat belt adjustment mechanism described above. [Explanation of symbols]
