Description

Technical Field

[0001] The utility model relates to a child safety seat, in particular to an automatically deployable seat belt system. Background Art

[0002] A child safety seat is designed for children of different weights or ages. It is used to restrain a child in the seat to effectively improve the safety of children when riding in a vehicle. A seat belt - a shoulder belt and a crotch belt - is usually provided on the child safety seat and is fastened by a safety buckle. When not in use, the seat belt is usually stacked messily in the safety seat. When an infant is seated, it is usually necessary to first push aside the seat belt to make room for the seat, and its design is less user - friendly. Especially when a user holds a child alone, since both hands are used to hold the child, without the help of others, it is difficult to free one hand to first push aside the seat belt stacked in the safety seat. Instead, the child can only be placed in the seat first, and then the seat belt is pulled out from under the child's body, which not only makes the child uncomfortable but also easily wakes up a sleeping child. Therefore, there is still room for improvement in existing child safety seats. Summary of the Utility Model

[0042] The following embodiments are further explanations and supplements to the present utility model, and do not constitute any limitation to the present utility model.

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

[0044] Among them, the first elastic member 10 is respectively arranged on the left and right sides of the seat body 100, and is used to traction the shoulder strap 40 and the male buckle 50 to automatically deploy. One end of the first elastic member 10 is connected to the seat body 100, and the other end extends into a free end. The first elastic member 10 not only has elasticity, but also has a certain supporting effect.

[0045] The second elastic member 20 is arranged on the seat portion of the seat body 100. One end of it is connected to the seat body 100, and the other end extends into a free end. The second elastic member 20 is located in the crotch strap position area and can act as a crotch strap. The second elastic member 20 has elasticity, can be bent to be suitable for safety restraint, and can automatically flatten when unbuckled.

[0046] The connecting strap 30 is respectively connected to the free ends of the first elastic members 10. It is connected between the first elastic member 10 and the male buckle 50 and is used to improve the use comfort. For the first elastic members 10 on the left and right sides, connecting straps 30 are respectively arranged thereon. The connecting strap 30 can be a webbing with a fixed length or in the form of an adjustable-length webbing, and a well-known webbing can be selected. When the connecting strap 30 is in the form of an adjustable-length webbing, the connecting strap 30 can also be used to adjust the tightness in the width direction during use.

[0047] The shoulder strap 40 is arranged on the seat body 100 and is used to be worn on the user's shoulder position during safety restraint to restrain the user on the safety seat. Usually, the shoulder strap 40 is movably arranged between 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 unbuckling.

[0049] The female buckle 60 is arranged on the free end of the second elastic member 20 and can move along with the second elastic member 20. In the default state, the female buckle 60 is in a position that does not affect sitting. When the second elastic member 20 bends, the female buckle 60 moves along with the second elastic member 20 to be suitable for safety restraint. When unbuckled, the female buckle 60 moves to a position that does not affect sitting along with the automatic deployment of the second elastic member 20.

[0050] The male buckle 50 is arranged on the connecting strap 30 and / or the shoulder strap 40. When it is connected to the female buckle 60, it can connect the shoulder strap 40 with the crotch strap and the connecting strap 30 to form a safety restraint seat belt to safely restrain the user on the safety seat.

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

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

[0054] Since the first elastic members 10 are provided on both the left and right sides of the safety seat, and the shoulder strap 40 usually includes a left shoulder strap 41 and a right shoulder strap 42, therefore, the male buckle 50 is at least divided into two parts: a left part 51 and a right part 52. Among them, the left part 51 is provided on the left side of the safety seat and is connected 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 is connected to the connecting strap 30 and the shoulder strap 40 on the right side of the safety seat.

[0055] The left part 51 and the right part 52 need to be connected to the female buckle 60 together to connect the shoulder straps 40, the connecting straps 30 on both sides and the crotch strap to provide a safety restraint function.

[0056] Among them, the structures of the left part 51 and the right part 52 can be the same or different, as long as the overall formed male buckle 50 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 right part 52 can be a single component or multiple components, and can be specifically set according to needs.

[0058] For example, the left part 51 can be a half male buckle 50 formed integrally, with two webbing holes provided thereon, which are respectively connected to the connecting strap 30 and the shoulder strap 40.

[0059] Another example is that the left part 51 can include two independent components, with webbing holes respectively provided on each independent component, one of which is connected to the shoulder strap 40 and one of which is connected to the connecting strap 30.

[0060] When it is necessary to securely fasten the user to 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 belt 40 are connected together due to the engagement of the male buckle 50 and the female buckle 60. At this time, they enclose to form a restraint state, which can provide a safety restraint function for the user.

[0061] When the male buckle 50 is connected to the female buckle 60 (as Figure 2 shown), the male buckle 50 and the female buckle 60 are pulled towards 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, thus constantly having a tendency to expand outwards. When the male buckle 50 is disconnected from the female buckle 60, the first elastic member 10 and the second elastic member 20 elastically reset. The first elastic member 10 can then pull the shoulder belt 40 and the male buckle 50 to automatically expand towards 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 belt 40, the crotch belt, the male buckle 50, and the female buckle 60 will not pile up on the seat part, but will automatically expand to the two sides and the front side of the seat (as Figure 1 shown), thus not affecting the user's seating and facilitating the user's use.

[0062] Furthermore, the first elastic member 10 is in a long strip shape and is made of an elastic material. It has a certain elasticity and strength as a whole. Therefore, it can be bent and can reset after bending, thereby driving the connecting belt 30, the shoulder belt 40, and the male buckle 50 to automatically expand to both sides of the seat body 100. In this embodiment, the first elastic member 10 is made of a silicone material, which can not only meet the elastic requirements but also be soft and skin-friendly, suitable for children's safety seats. In other embodiments, the first elastic member 10 can also be made of other materials.

[0063] Furthermore, in the default state, the first elastic member 10 is straightly arranged 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. Among them, the elastic section 12 is connected between the connecting section 11 and the extension section 13, and the first elastic member 10 is integrally constructed in a bent state with a rounded corner 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 through fasteners such as screws.

[0066] The extension section 13 abuts against the inner walls on the left and right sides of the seat body 100 and is arranged to extend in the second direction. Among them, the second direction is different from the first direction. In this embodiment, the included angle between the second direction and the second direction is about 75 - 105°. Of course, the angle between the second direction and the first direction is not limited.

[0067] Since the first elastic member 10 is an integrally formed structure, when the extending directions of the connecting section 11 and the extension section 13 are different, the elastic section 12 will be in an elastic deformation state when connected to the connecting section 11 and the extension section 13. Therefore, it makes the extension section 13 always have a tendency to abut against the inner wall of the seat body 100. In other words, if there is no abutment against the inner wall of the seat body 100, the extension section 13 will return to a position coplanar or substantially coplanar with the connecting section 11.

[0068] When the extension section 13 abuts against the inner walls on the left and right sides of the seat body 100, it can be in partial abutment with the seat body 100 or in full abutment with the seat body 100. In this embodiment, the extension section 13 is in partial abutment with the inner walls on the left and right sides of the seat body 100, and the end portion extends out of the seat body 100. The end portion of the extension section 13 is the free end of the first elastic member 10.

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

[0070] The connecting belt 30 can have a fixed length or an adjustable length. It can be an elastic belt or a non-elastic belt. Usually, the connecting belt 30 is selected as 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 well to achieve the connection.

[0072] Of course, an adjustment buckle can also be provided on the connecting belt 30. After the connecting belt 30 is sleeved on the corresponding parts of the first elastic member 10 and the male buckle 50, the length of the connecting belt 30 can be adjusted through the adjustment buckle. The structure of setting an adjustment buckle on the connecting belt 30 to adjust the length can refer to the known technology.

[0073] Further, the second elastic member 20 is strip-shaped and made of an elastic material. As a whole, it has a certain elasticity and strength. Therefore, it can be fully bent and then reset, so that it can automatically flatten and drive the female buckle 60 to unfold to a position where it does not affect sitting. In the default state, the second elastic member 20 is attached to the surface of the seat portion.

[0074] Further, the second elastic member 20 extends as a whole along the third direction, and its connecting end is attached to the surface of the seat portion and fixedly connected to the seat portion. When the second elastic member 20 is not pulled, the second elastic member 20 is entirely attached to the seat portion, and the female buckle 60 is also attached or substantially attached to the seat portion. For the convenience of use, the connecting end of the second elastic member 20 is located at the position corresponding to the crotch, and the free end of the second elastic member 20 is located in front of the crotch. Here, the front refers to the position where the face faces when sitting normally.

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

[0076] In this embodiment, a lock hole 61 is provided on the female buckle 60, a protruding lock tongue 501 is provided on the male buckle 50, a lock groove is provided in the circumferential direction of the lock tongue 501, and a locking member is provided inside the female buckle 60; when the lock tongue 501 enters the lock hole 61, the locking member can be horizontally inserted into the lock groove of the lock tongue 501 to engage with the lock tongue 501, so that the male buckle 50 and the female buckle 60 are connected together. To unlock, a release operation member 62 is movably provided on the female buckle 60, and the release operation member 62 can drive the locking member to move and disengage from the lock tongue 501, so that the male buckle 50 and the female buckle 60 are separated. The movement form of the release operation member 62 is not limited, and it can be two-way pressing or pulling, etc.

[0077] To ensure that the female buckle 60 does not affect sitting in the default state, the female buckle 60 is fixedly provided at the free end of the second elastic member 20. To improve the convenience of the unlocking operation and the aesthetics of use, the female buckle 60 is in a state where the lock hole 61 faces upward in the default state, and the axial direction of the lock hole 61 is perpendicular to the third direction. When connection is required, the female buckle 60 and the second elastic member 20 are pulled inward.

[0078] As mentioned above, the male buckle 50 includes a left part 51 and a right part 52. When the lock tongue 501 protrudes from the male buckle 50, the lock tongue 501 can be provided only on the left part 51, or only on the right part, or partial lock tongues 501 are respectively provided on the left part 51 and the right part 52. When the left part 51 and the right part 52 are spliced, a complete lock tongue 501 is formed and can enter the lock hole 61 to engage with the locking member.

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

[0080] Wherein, the first male buckle part 502 is connected to the connecting band 30, and the second male buckle part 503 is connected to the shoulder strap 40. Between the shoulder strap 40 and the connecting band 30, they can be connected together through the combination of the first male buckle part 502 and the second male buckle part 503, and can be separated through the separation of the first male buckle part 502 and the second male buckle part 503.

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

[0082] Further, to achieve the separable connection of the first male buckle part 502 and the second male buckle part 503, a concave positioning groove 5031 is provided on the joint surface of the second male buckle part 503 facing the first male buckle part 502, and a clamping groove 5032 communicating with the positioning groove 5031 is provided in the positioning groove 5031. The clamping groove 5032 is a stepped groove, and the part thereof communicating with the positioning groove 5031 is relatively narrow, and other parts are relatively wide, so that a stepped groove can be formed to play a limiting role. In addition, to facilitate the insertion of the first male buckle part 502, one end of the clamping groove 5032 communicates with the side surface of the second male buckle part 503.

[0083] A protruding clamping strip part 5021 is provided on the joint surface of the first male buckle part 502 facing the second male buckle part 503. The shape of the clamping strip part 5021 matches the shape of the positioning groove 5031. In this embodiment, its cross-section is L-shaped, and in other embodiments, its cross-section can also be T-shaped or other shapes.

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

[0085] The shape engagement between the clamping strip part 5021 and the clamping groove 5032 makes the first male buckle part 502 and the second male buckle 50 unable to be separated along the axial direction of the locking tongue 501. The shape fit between the positioning groove 5031 and the first male buckle part 502 makes the first male buckle part 502 lap on the second male buckle part 503, which can improve the integrity and is more conducive to the connection of the left part 51, the right part 52 and the female buckle 60.

[0086] Further, to play a locking role, improve the use safety, and prevent the first male buckle part 502 and the second male buckle part 503 from being accidentally separated, an elastic arm 5033 is provided at the bottom of the card slot 5032, a card convex part 5034 is provided at the free end of the elastic arm 5033, and a card hole 5022 is provided on the card strip part 5021. Through the cooperation of the card convex part 5034 and the card hole 5022, the first male buckle part 502 and the second male buckle part 503 can be prevented from being accidentally separated.

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

[0088] The card convex part 5034 is provided at the free end of the elastic arm 5033 and extends into the card slot 5032. That is, the card convex part 5034 is located in the card slot 5032.

[0089] When the card strip part 5021 is inserted into the card slot 5032, the end of the card strip part 5021 presses the card convex part 5034, so that the free end of the elastic arm 5033 is elastically displaced, and the card convex part 5034 does not hinder the continuous advancement of the card strip part 5021. When the card strip part 5021 moves to a position where its card hole 5022 corresponds to the card convex part 5034, the elastic arm 5033 elastically resets, and the card convex part 5034 can be made to snap into the card hole 5022, so that the card strip part 5021 cannot move.

[0090] To facilitate the insertion of the card strip part 5021, a guiding inclined surface is provided on one side of the card convex part 5034 facing the insertion opening.

[0091] When there is no external force assistance, the first male buckle part 502 and the second male buckle part 503 are connected together, and they cannot be separated along the axial direction of the lock tongue 501, nor can they be separated in the direction opposite to the direction of inserting into the card slot 5032.
