Description

Technical Field

[0001] The present invention relates to a child safety seat, and in particular to a safety belt system that can be automatically deployed. Background Art

[0002] Child safety seats are designed for children of varying weights and ages, restraining them in the seat and effectively improving their safety. Child safety seats typically feature seatbelts—shoulder and lap straps—fastened with safety buckles. When not in use, these seatbelts are often cluttered and stacked inside the seat. When an infant or toddler is seated, the seatbelts often need to be untied to make room, making this design less user-friendly. This is especially true when a user is carrying a child alone. Since they need both hands to support the child, it's difficult to free one hand to untie the seatbelts without assistance. Instead, they have to place the child in the seat first and then pull the seatbelts out from under the child's body. This is not only uncomfortable but can easily wake a sleeping child. Therefore, existing child safety seats still require improvement. Summary of the Invention

[0042] The following examples are provided to further explain and supplement the present invention and do not constitute any limitation to the present invention.

[0043] like Figures 1 to 8 As shown, the automatically deployable safety belt system of the present invention includes a seat body 100 , a first elastic member 10 , a second elastic member 20 , a connecting belt 30 , a shoulder belt 40 , a male buckle 50 and a female buckle 60 .

[0044] First elastic members 10 are located on either side of the seat body 100, pulling the shoulder straps 40 and male buckles 50 to automatically deploy. One end of each first elastic member 10 is connected to the seat body 100, while the other end extends free. The first elastic members 10 are not only elastic but also provide a certain degree of support.

[0045] The second elastic member 20 is disposed on the seat portion of the seat body 100, with one end connected to the seat body 100 and the other end extending to form a free end. The second elastic member 20 is located in the crotch strap area and functions as a crotch strap. The second elastic member 20 is elastic and bends for secure restraint, and automatically flattens when unfastened.

[0046] The connecting straps 30 are connected to the free ends of the first elastic members 10, connecting between the first elastic members 10 and the male buckle 50 to enhance user comfort. Connecting straps 30 are provided on the left and right first elastic members 10. These connecting straps 30 can be fixed-length or adjustable-length webbing, and are commonly used. When the adjustable-length webbing is used, the connecting straps 30 can also be used to adjust the tightness of the width during use.

[0047] The shoulder strap 40 is provided on the seat body 100 and is used to be worn on the user's shoulder position during safety restraint to restrain the user in the safety seat. Typically, the shoulder strap 40 is movably provided with the seat body 100 to facilitate adjusting the length of the shoulder strap 40.

[0048] The male buckle 50 and the female buckle 60 can be connected together to form a safety buckle, and the male buckle 50 and the female buckle 60 can be separated by unfastening.

[0049] The female buckle 60 is provided on the free end of the second elastic member 20 and is movable with the second elastic member 20. In the default state, the female buckle 60 is in a position that does not interfere with seating. When the second elastic member 20 bends, the female buckle 60 moves with the second elastic member 20, providing a secure restraint. When unfastened, the female buckle 60 automatically expands with the second elastic member 20 and moves to a position that does not interfere with seating.

[0050] The male buckle 50 is provided on the connecting belt 30 and / or the shoulder belt 40. When connected with the female buckle 60, the shoulder belt 40 can be connected with the crotch belt and the connecting belt 30 to form a safety belt for safety restraint, so as to safely restrain the user in the safety seat.

[0051] In some embodiments, the male buckle 50 is provided on the connecting belt 30, and the shoulder strap 40 can be freely passed through the webbing hole on the male buckle 50 to form a detachable connection with the male buckle 50; at this time, the connection between the shoulder strap 40 and the male buckle 50 is freely set by the user.

[0052] In some embodiments, the male buckle 50 is provided on the shoulder strap 40, and the connecting belt 30 can be freely passed through the webbing hole on the male buckle 50 to form a detachable connection with the male buckle 50. At this time, the connection between the connecting belt 30 and the male buckle 50 is freely set by the user.

[0053] In some embodiments, the male buckle 50 is provided on the connecting belt 30 and the shoulder strap 40 , and the user does not need to connect the male buckle 50 by himself, and the male buckle 50 is always connected to the connecting belt 30 and the shoulder strap 40 .

[0054] Since the first elastic member 10 is provided on both the left and right sides of the safety seat, and the shoulder straps 40 generally include a left shoulder strap 41 and a right shoulder strap 42, the male buckle 50 is divided into at least two parts: a left part 51 and a right part 52. The left part 51 is provided on the left side of the safety seat and connects to the connecting strap 30 and the shoulder strap 40 on the left side of the safety seat; the right part 52 is provided on the right side of the safety seat and connects to the connecting strap 30 and the shoulder strap 40 on the right side of the safety seat.

[0055] The left portion 51 and the right portion 52 are connected to the female buckle 60 to connect the shoulder straps 40 and the connecting strap 30 on the left and right sides to the crotch strap to provide a safety restraint function.

[0056] The structures of the left portion 51 and the right portion 52 may be the same or different, as long as the overall structure forms a male buckle 50 that can be connected to the female buckle 60 .

[0057] In addition, the left part 51 can be a single component or multiple components. Similarly, the left part 51 can be a single component or multiple components, and can be specifically configured according to needs.

[0058] For example, the left portion 51 may be an integrally formed half male buckle 50 , which is provided with two webbing holes for connecting to the connecting strap 30 and the shoulder strap 40 , respectively.

[0059] For another example, the left portion 51 may include two independent components, each of which is provided with a webbing hole, one of which is connected to the shoulder strap 40 , and the other is connected to the connecting strap 30 .

[0060] When the user needs to be safely restrained in the safety seat, the male buckle 50 is connected to the female buckle 60. At this time, the first elastic member 10, the second elastic member 20, the connecting belt 30, and the shoulder strap 40 are connected together due to the engagement of the male buckle 50 and the female buckle 60. At this time, the enclosure is in a restrained state, which can provide a safe restraint for the user.

[0061] When the male buckle 50 is connected to the female buckle 60 (as Figure 2As shown), the male buckle 50 and the female buckle 60 are pulled to the middle area of ​​the seat body 100 for engagement. At this time, the first elastic member 10 and the second elastic member 20 are elastically bent, so that they always have a tendency to expand outward. When the male buckle 50 and the female buckle 60 are disconnected, the first elastic member 10 and the second elastic member 20 are elastically reset, and the first elastic member 10 can pull the shoulder strap 40 and the male buckle 50 to automatically expand toward the left and right sides of the seat body 100, and the second elastic member 20 drives the female buckle 60 to automatically expand. In this way, the shoulder strap 40, the crotch strap, the male buckle 50, and the female buckle 60 will not be piled up on the seat part, but will automatically expand to the sides and front of the seat (as shown). Figure 1 As shown), it does not affect seating and is convenient for users.

[0062] Furthermore, the first elastic member 10 is elongated and made of an elastic material. It possesses a certain degree of elasticity and strength, allowing it to bend and then return to its original position, thereby automatically deploying the connecting strap 30, shoulder strap 40, and male buckle 50 to both sides of the seat body 100. In this embodiment, the first elastic member 10 is made of silicone, which not only meets elastic requirements but is also soft and skin-friendly, making it suitable for child safety seats. In other embodiments, the first elastic member 10 may also be made of other materials.

[0063] Furthermore, in a default state, the first elastic member 10 is uprightly disposed on the left and right sides of the seat body 100 .

[0064] Furthermore, the first elastic member 10 includes an integrally formed connecting section 11, an elastic section 12, and an extension section 13. The elastic section 12 is connected between the connecting section 11 and the extension section 13, and the first elastic member 10 is configured as a whole in a bent state with a rounded transition.

[0065] The connecting section 11 is arranged along the first direction and is fixedly connected to the seat body 100. The connecting section 11 and the seat body 100 can be fixedly connected by fasteners such as screws.

[0066] The extension section 13 abuts against the inner sidewalls of the left and right sides of the seat body 100 and extends along a second direction. The second direction is different from the first direction. In this embodiment, the angle between the second direction and the first direction is approximately 75-105°. Of course, the angle between the second direction and the first direction is not limited.

[0067] Because the first elastic member 10 is an integrally formed structure, when the connecting section 11 and the extending section 13 extend in different directions, the elastic section 12 is elastically deformed when connected to the connecting section 11 and the extending section 13. This causes the extending section 13 to constantly tend to abut against the inner sidewall of the seat body 100. In other words, without the inner sidewall of the seat body 100 abutting against it, the extending section 13 will return to a position coplanar or substantially coplanar with the connecting section 11.

[0068] When the extension section 13 abuts the left and right inner sidewalls of the seat body 100, it may be partially or completely in abutment with the seat body 100. In this embodiment, the extension section 13 partially abuts the left and right inner sidewalls of the seat body 100, with the ends extending outside the seat body 100. The ends of the extension section 13 constitute the free ends of the first elastic member 10.

[0069] To facilitate installation of the connecting strap 30, a first mounting portion 14 is provided on the free end of the first elastic member 10. A first mounting hole 141 is defined in the first mounting portion 14. The connecting strap 30 passes through the first mounting hole 141 and is connected to the first mounting portion 14. The other end of the connecting strap 30 is connected to the male buckle 50. Specifically, the connecting strap 30 on the left side of the seat body 100 is connected to the left portion 51 of the male buckle 50, while the connecting strap 30 on the right side of the seat body 100 is connected to the right portion 52 of the male buckle 50.

[0070] The connecting belt 30 can be fixed in length or adjustable in length. It can be an elastic belt or a non-elastic belt. Typically, the connecting belt 30 is a webbing.

[0071] When the connecting belt 30 is a webbing with a fixed length, both ends of the connecting belt 30 are sleeved on the corresponding parts of the first elastic member 10 and the male buckle 50 and then sewn together to achieve connection.

[0072] Of course, the connecting belt 30 may also be provided with an adjustment buckle. After the connecting belt 30 is sleeved on the first elastic member 10 and the corresponding portion of the male buckle 50, the length of the connecting belt 30 can be adjusted by the adjustment buckle. The structure of providing the adjustment buckle on the connecting belt 30 to adjust the length can refer to the known art.

[0073] Furthermore, the second elastic member 20 is in the form of an elongated strip and is made of an elastic material. It has a certain degree of elasticity and strength as a whole. Therefore, it can be completely bent and can be reset after bending, thereby automatically flattening and driving the female buckle 60 to a position that does not affect seating. In the default state, the second elastic member 20 is in contact with the surface of the seat portion.

[0074] Furthermore, the second elastic member 20 extends entirely along the third direction, with its connecting end contacting and securely connected to the seat surface. When the second elastic member 20 is not pulled, the entire second elastic member 20 rests on the seat, and the female buckle 60 also contacts or substantially contacts the seat. For ease of use, the connecting end of the second elastic member 20 is positioned at a location corresponding to the crotch, while the free end of the second elastic member 20 is positioned in front of the crotch. The term "front" refers to the position toward which one's face faces when seated.

[0075] The male buckle 50 and the female buckle 60 are used to achieve a detachable connection. The principle structure of the detachable connection between the male buckle 50 and the female buckle 60 is not limited, as long as it can achieve a detachable connection.

[0076] In this embodiment, the female buckle 60 is provided with a locking hole 61, the male buckle 50 is provided with a protruding locking tongue 501, and a locking groove is formed around the locking tongue 501. A locking element is provided within the female buckle 60. When the locking tongue 501 enters the locking hole 61, the locking element can be laterally inserted into the locking groove of the locking tongue 501 and engage with the locking tongue 501, thereby connecting the male buckle 50 and the female buckle 60. To release the buckle, a release operating member 62 is movably provided on the female buckle 60. The release operating member 62 can move the locking element and disengage the locking tongue 501, thereby separating the male buckle 50 and the female buckle 60. The release operating member 62 can be operated in any manner and can be a two-way pressing or pulling motion.

[0077] To ensure that the female buckle 60 does not interfere with seating in the default position, it is fixed to the free end of the second elastic member 20. To enhance the convenience of unfastening and aesthetics, the female buckle 60 is positioned with its locking hole 61 facing upward in the default position, with the axial direction of the locking hole 61 perpendicular to the third direction. To connect, the female buckle 60 and the second elastic member 20 are pulled inward.

[0078] As previously mentioned, the male buckle 50 includes a left portion 51 and a right portion 52. When the locking tongue 501 is protruding from the male buckle 50, the locking tongue 501 can be provided only on the left portion 51, or only on the right portion, or partial locking tongues 501 can be provided on both the left portion 51 and the right portion 52. When the left portion 51 and the right portion 52 are spliced ​​together, a complete locking tongue 501 is formed, which can enter the lock hole 61 and engage with the locking member.

[0079] Furthermore, the left portion 51 and the right portion 52 respectively include a first male buckle portion 502 and a second male buckle portion 503 that are separable and connectable together.

[0080] The first male buckle 502 is connected to the connecting belt 30, and the second male buckle 503 is connected to the shoulder strap 40. The shoulder strap 40 and the connecting belt 30 can be connected together by the combination of the first male buckle 502 and the second male buckle 503, and can be separated by the separation of the first male buckle 502 and the second male buckle 503.

[0081] The first male buckle portion 502 and the second male buckle portion 503 are respectively provided with webbing holes for connecting the connecting belt 30 and the shoulder strap 40 respectively.

[0082] Furthermore, to achieve a detachable connection between the first male buckle 502 and the second male buckle 503, a concave positioning groove 5031 is provided on the engaging surface of the second male buckle 503 facing the first male buckle 502. Within this positioning groove 5031 is a latching groove 5032 that extends through the positioning groove 5031. The latching groove 5032 is a stepped groove, relatively narrow where it extends through the positioning groove 5031 and relatively wide elsewhere. This creates a stepped groove that acts as a retaining mechanism. Furthermore, to facilitate insertion of the first male buckle 502, one end of the latching groove 5032 extends through the side surface of the second male buckle 503.

[0083] A protruding clip portion 5021 is provided on the engaging surface of the first male buckle portion 502 facing the second male buckle portion 503. The shape of the clip portion 5021 matches the shape of the positioning groove 5031. In this embodiment, its cross section is L-shaped. In other embodiments, its cross section may also be T-shaped or other shapes.

[0084] The locking strip portion 5021 can be inserted into the locking groove 5032 along the side of the second male buckle portion 503 to be in shape engagement with the locking groove 5032 , so that the first male buckle portion 502 is at least partially embedded in the positioning groove 5031 .

[0085] The shape of the locking strip 5021 and the locking groove 5032 prevents the first male buckle 502 and the second male buckle 50 from being separated along the axial direction of the lock tongue 501. The shape of the positioning groove 5031 matches the shape of the first male buckle 502, allowing the first male buckle 502 to overlap the second male buckle 503, improving the integrity and facilitating the connection between the left and right parts 51, 52 and the female buckle 60.

[0086] Furthermore, to provide a locking function, improve safety, and prevent accidental separation of the first male buckle 502 and the second male buckle 503, a spring arm 5033 is provided at the bottom of the locking slot 5032, a locking protrusion 5034 is provided at the free end of the spring arm 5033, and a locking hole 5022 is provided on the locking strip 5021. The engagement of the locking protrusion 5034 with the locking hole 5022 prevents accidental separation of the first male buckle 502 and the second male buckle 503.

[0087] More specifically, a hollow hole is provided at the bottom of the locking slot 5032, so that one end of the elastic arm 5033 is connected to the second male buckle 503, and the other end of the elastic arm 5033 is separated from the second male buckle 503 and is free. In this way, the elastic arm 5033 has a certain elasticity, and its free end can be elastically displaced.

[0088] The locking protrusion 5034 is provided on the free end of the elastic arm 5033 and extends into the locking slot 5032. That is, the locking protrusion 5034 is located in the locking slot 5032.

[0089] When the clip 5021 is inserted into the slot 5032, the end of the clip 5021 pushes against the protruding portion 5034, causing the free end of the elastic arm 5033 to elastically displace, and the protruding portion 5034 does not hinder the continued movement of the clip 5021. When the clip 5021 moves to a position where its locking hole 5022 corresponds to the protruding portion 5034, the elastic arm 5033 elastically returns to its original position, causing the protruding portion 5034 to lock into the locking hole 5022, preventing the clip 5021 from moving.

[0090] In order to facilitate the insertion of the locking strip portion 5021 , a guiding slope is provided on the side of the locking protrusion 5034 facing the insertion opening.

[0091] Without external force, the first male buckle 502 and the second male buckle 503 are connected together and cannot be separated along the axial direction of the locking tongue 501 or in the direction opposite to the insertion into the locking slot 5032. At this time, the first elastic member 10, the connecting strap 30, the left portion 51, and the left shoulder strap 41 on the left side of the safety seat are connected together, while the first elastic member 10, the connecting strap 30, the right portion 52, and the right shoulder strap 42 on the right side of the safety seat are connected together.

[0092] When it is necessary to separate the first male buckle part 502 and the second male buckle part 503, a tool is used to elastically displace the free end of the elastic arm 5033 outward so that the locking protrusion 5034 exits the locking hole 5022. In this way, the locking strip part 5021 can be pulled out of the locking groove 5032 to achieve the separation of the first male buckle part 502 and the second male buckle part 503.
