Description

A device and a safety seat with cross-strap directional retention function Technical Field

[0001] This application relates to the field of automotive parts technology, and in particular to a device and a safety seat with a cross-strap directional retention function. Background Technology

[0002] A child safety seat is a car seat specifically designed for children to ensure they are adequately protected while the car is in motion. Because children's body structure differs from adults, ordinary car seats cannot provide sufficient safety. Therefore, child safety seats use specialized designs and safety systems to help reduce injuries to children in the event of a car accident or collision.

[0003] In terms of seat belt design, child safety seats differ significantly from ordinary seats. For example, child safety seats mostly use a five-point harness, which has two shoulder straps, two lap belts, and one crotch strap. However, in actual use, because the crotch strap is relatively soft, after the buckle is subjected to tension, the position of the buckle end is unstable and it is easy to tilt in different directions, which can cause the child to be crushed, resulting in bumps and injuries to the child.

[0004] Therefore, a solution is needed to address at least one of the aforementioned problems.

[0005] Utility Model Content

[0006] To address the shortcomings of existing technologies, this application proposes a device and a safety seat with a lap belt directional holding function, which can achieve directional tilting and holding of the lap belt.

[0020] In one specific embodiment, one of the first directional member and the second directional member is provided with a first magnetic attraction member, and the other of the two is provided with a second magnetic attraction member;

[0021] The first magnetic attractor attracts the second magnetic attractor to generate a restraining force that prevents the cross-belt body from deviating from the holding area.

[0022] In one specific embodiment, the first magnetic attractor includes a first magnet or magnetic metal, and the second magnetic attractor includes a second magnet;

[0023] The contact surfaces of the first magnet and the second magnet are arranged with opposite polarities;

[0024] The first magnet includes one or more sub-magnets;

[0049] Example

[0050] This application provides a device with a cross-belt orientation retention function, as shown in Figures 1 and 2, including: a locking fastener 1 and a cross-belt body 2;

[0051] The cross strap 2 has a free end 21 and a fixed end 22. The free end 21 is used to connect to the locking fastener 1, and the fixed end 22 is used to connect to the seat frame 3. The cross strap 2 is also used to connect to the seat frame 3, generating a restraining force that prevents the cross strap 2 from deviating from the holding area 40 on the seat frame 3, so that the cross strap 2 is kept in the holding area 40.

[0052] Among them, the seat frame 3 is a component of the seat, mainly the frame of the seat.

[0053] Specifically, the dotted lines in each figure indicate the location of the retention area 40; however, there are no restrictions on the specific location of the retention area 40.

[0054] Specifically, in some embodiments of this application, the portion of the cross strap 2 located between the free end 21 and the fixed end 22 is connected to the seat frame 3 to generate a restraining force that prevents the cross strap 2 from deviating from the holding area 40 on the seat frame 3;

[0055] Of course, there are no restrictions on the specific connection method between the cross belt body 2 and the seat frame 3, nor are there any restrictions on the specific connection position of the cross belt body 2.

[0056] Since the free end 21 of the belt body 2 connected to the fastener 1 is constrained in the holding area 40, the possibility of the fastener 1 bumping or injuring children can be avoided, thereby improving the safety of using the belt.

[0057] Furthermore, the device also includes a first directional member 41 and / or a second directional member 42;

[0058] In one specific embodiment, as shown in FIG2, the cross strap 2 is connected to the seat frame 3 via a first directional member 41 or a second directional member 42 to form a holding area 40 for holding the cross strap 2 at least at the connection with the seat frame 3.

[0059] More specifically, the crossbody belt 2 can be connected to the seat frame 3 via the second directional member 42. In some embodiments of this application, the second directional member 42 is an elastic band. One end of the elastic band is connected to the area on the crossbody belt 2 except for the free end 21. The connection between the elastic band and the seat frame 3 forms a holding area 40. The elastic band connects the seat frame 3 and the crossbody belt 2 so as to generate a constraint force that keeps the crossbody belt 2 in the holding area 40 through elastic deformation, thereby achieving directional holding of the crossbody belt 2.

[0060] Of course, there are no restrictions on the specific structure of the first directional component 41 and the second directional component 42, nor are there any restrictions on whether the connection between the cross strap body 2 and the seat frame 3 is a detachable connection or a fixed connection.

[0061] Alternatively, as shown in Figure 1, in another embodiment, the crossbody strap 2 is connected to the seat frame 3 via a first directional member 41 and a second directional member 42. The first directional member 41 is disposed on the seat frame 3 to form a holding area 40 on the seat frame 3 for holding the crossbody strap 2. The crossbody strap 2 is provided with a second directional member 42 corresponding to the first directional member 41. The first directional member 41 is connected to the second directional member 42 to generate a restraining force that prevents the crossbody strap 2 from deviating from the holding area 40, so that the crossbody strap 2 is held in the holding area 40.

[0062] Specifically, in some embodiments of this application, the first directional member 41 may be detachably connected to the second directional member 42, or may be fixedly connected to the second directional member 42, in order to generate a restraining force that prevents the cross-belt body 2 from deviating from the holding region 40.

[0063] Understandably, this embodiment has a simple structure and strong feasibility. The directional holding function of the cross strap can be achieved simply by setting the first directional member 41 and the second directional member 42.

[0064] Through the design of the first directional component 41 and the second directional component 42, the free end 21 of the lap belt can automatically tilt towards the holding area 40 and remain in the holding area 40 after unlocking, and the lap belt will not easily deviate, which has strong stability and certainty; thus, no adjustment is required before or after use, which is convenient for users and optimizes the user experience.

[0065] Furthermore, as shown in Figures 3 to 5, the fixed end 22 is also provided with a stabilizer 221, and a stabilizer seat 222 matching the stabilizer 221 is provided on the side of the seat frame 3 opposite to the first directional member 41. The movement of the stabilizer 221 is restricted by the stabilizer 221 abutting against the stabilizer seat 222.

[0066] Understandably, the cooperation between the stabilizer 221 and the stabilizer seat 222 can effectively limit the movement of the fixed end 22, prevent the cross strap 2 from shifting or loosening due to external forces, thereby enhancing the stability of the seat belt system and enabling it to maintain a stable restraint force during collisions or sudden deceleration.

[0067] By ensuring a firm fit between the stabilizer 221 and the stabilizer seat 222, the relative movement between the stabilizer 221 and the seat frame 3 can be reduced, thereby reducing wear between the cross belt body 2 and the seat frame 3 and extending the service life of the cross belt system.

[0068] Furthermore, since the movement of the stabilizer 221 is restricted, it can effectively prevent the stabilizer 221 from shaking randomly and reduce the generation of noise.

[0069] Specifically, in some embodiments of this application, the stabilizer 221 is a swivel buckle;

[0070] Of course, no restrictions are placed on the specific structural form of the stabilizer 221.

[0071] Furthermore, as shown in Figures 10 and 11, the stabilizer 222 is provided with a mounting hole 223, and the free end 21 of the cross belt body 2 passes through the mounting hole 223 to connect to the locking fastener 1.

[0072] The extension direction of the mounting hole 223 is biased toward the direction of the first directional member 41.

[0073] Specifically, in some embodiments of this application, the stabilizer 221 is located at the bottom of the seat frame 3. After the free end 21 of the cross strap 2 passes through the mounting hole 223 and connects to the buckle 1, the stabilizer 221 abuts against the stabilizer seat 222.

[0074] Understandably, the free end 21 of the cross belt body 2 passes through the mounting hole 223 of the stabilizer 222 and is connected to the locking member 1. The first directional member 41 provides an upward pulling force, which can further enhance the connection stability between the stabilizer 221 and the stabilizer 222, making the stabilizer 221 less prone to shaking, thereby avoiding noise generation to a certain extent.

[0075] The extension direction of the mounting hole 223 is biased towards the direction of the first directional member 41, and the free end 21 of the cross belt body 2 passes through the mounting hole 223. The extension direction of the mounting hole 223 can guide the cross belt body 2, and to a certain extent guide the cross belt body 2 to tilt in a preset direction; and the force on the cross belt body 2 can also be transmitted in a reasonable direction, so that the cross belt body 2 tilts onto the holding area 40, and is held on the holding area 40 through the connection of the first directional member 41 and the second directional member 42.

[0076] Specifically, as shown in Figures 4, 6, 8 and 10, in some embodiments of this application, the first directional member 41 includes a fixing member 51, and the second directional member 42 includes an elastic member 52.

[0077] More specifically, in some embodiments of this application, the fastener 51 can be a fastening plate, and the elastic element 52 can be an elastic band;

[0078] The elastic element 52 can also be a spring. Of course, there are no restrictions on the specific structure of the fixing element 51 and the elastic element 52.

[0079] One end of the elastic element 52 is connected to the cross belt body 2, and the other end of the elastic element 52 is connected to the fixing element 51 to generate a restraining force that prevents the cross belt body 2 from deviating from the holding area 40.

[0080] The elastic element 52 connects the cross belt body 2 and the fixing element 51. Through the elastic force of the elastic element 52 itself, it provides a constraint force to keep the cross belt body 2 in the holding area 40. This can prevent the cross belt body 2 from deviating from the predetermined holding area 40 when not in use, effectively reducing the risk of instability or slippage of the cross belt body 2, thereby improving the stability and reliability of the cross belt body 2.

[0081] The cross strap body 2 has a certain rigidity. Specifically, in some embodiments of this application, this design uses two layers of webbing sewn together and controls the sewing density to increase the rigidity of the webbing in order to provide support for the locking buckle 1; or a support member (not shown in the figure) is provided on the cross strap body 2 to enhance the support of the cross strap body 2 in order to support the locking buckle 1.

[0082] Furthermore, the combination of elastic element 52 and fixing element 51 results in a simple and easy-to-implement structure that avoids excessive component parts, thus simplifying the overall structure and reducing the complexity of manufacturing and maintenance.

[0083] Furthermore, as shown in Figure 4, a first connecting part 23 is provided on the side of the cross belt body 2 near the fixed end 22, and the fastener 51 includes a base 511 and a locking part 512.

[0084] The base 511 is provided with a first connecting post 515 that matches the first connecting part 23, and the engaging part 512 is provided with a connecting groove 514 that matches the first connecting post 515.

[0085] The first connecting post 515 is used to pass through the first connecting part 23 and connect to the connecting groove 514. One side of the engaging part 512 is used to abut against the first connecting post 515, and the other side of the engaging part 512 is used to abut against the base 511, so as to achieve a stable connection between the cross belt body 2 and the fastener 51.

[0086] Understandably, the first connecting post 515 passes through the first connecting part 23 and connects to the connecting groove 514. The engaging part 512 engages with the base 511 and the first connecting post 515 by abutting, so that the crossbody belt 2 can be stably connected to the fixing member 51. The presence of the first connecting post 515 provides the crossbody belt 2 with a connection point and a point of force. The engaging part 512 engages with the base 511 and the first connecting post 515, which can effectively prevent the crossbody belt 2 from loosening from the fixing member 51 during use, thereby enhancing the stability of the overall structure. At the same time, it reduces unnecessary friction or vibration between the crossbody belt 2 and the fixing member 51, which can effectively reduce the vibration and noise of the system.

[0087] Specifically, in some embodiments of this application, the seat frame 3 is clamped between the fixing member 51 and the fixing member 51 through the mutual cooperation of the first connecting part 23 and the fixing member 51, and the mutual cooperation of the stabilizing member 221 and the fixing end 22. The cross strap 2 between the fixing member 51 and the stabilizing member 221 is tightened, thereby providing a tension force to fix the fixing member 51 and the stabilizing member 221.

[0088] More specifically, in some embodiments of this application, the first connecting portion 23 includes a belt hole formed on the cross belt body 2; during the assembly process, the first connecting post 515 is inserted from one side of the belt hole and exits from the other side of the belt hole, thereby connecting the first connecting post 515 with the first connecting portion 23.

[0089] Furthermore, as shown in Figure 4, the fastener 51 is also provided with a slot 513, which is used to connect the elastic element 52.

[0090] The slot 513 facilitates the smooth insertion and secure fixing of the elastic element 52 within the slot 513, enhancing the connection stability between the elastic element 52 and the fixing element 51. The design of the slot 513 ensures a uniform distribution of the contact area between the elastic element 52 and the fixing element 51, resulting in a more uniform force distribution on the elastic element 52. Furthermore, the slot 513 also helps maintain the shape of the cross belt 2 to a certain extent, making it less prone to folding or winding.

[0091] Specifically, in some other embodiments of this application, the plane on which the slot 513 is located on the fastener 51 is the first plane, and the plane on which the first connecting post 515 is located is the second plane. The second plane fits into the seat frame 3, and there is a certain angle between the first plane and the second plane.

[0092] Understandably, the second plane fits into the seat frame 3, facilitating the connection between the fastener 51 and the seat frame 3, and providing a stable reference plane;

[0093] The presence of a certain angle between the first plane and the second plane facilitates the connection between the elastic element 52 and the fixing element 51 through the slot 513.

[0094] Furthermore, the shape of the fastener 51 includes a U-shape.

[0095] The U-shaped fastener 51 provides a larger contact surface, which can firmly connect the fastener 51 to the seat frame 3. The increased contact area makes the force distribution of the fastener 51 more uniform, thereby improving the overall stability of the structure. The U-shaped design on both sides of the support surface can effectively disperse the external impact or vibration, reducing the impact of concentrated stress on the fastener 51 or the connection part.

[0096] Furthermore, the stabilizer 222 includes multiple mounting holes 223, so that the mounting position of the cross strap 2 on the seat frame 3 is adjustable.

[0097] Understandably, the seat frame 3 is provided with multiple stabilizing seats 222 and multiple mounting holes 223, which makes it easy for users to adjust the installation position of the cross strap on the seat frame 3 according to actual needs, thereby enhancing the flexibility and versatility of use, meeting the diverse needs of users, and helping to optimize the user experience.

[0098] Specifically, in some other embodiments of this application, as shown in FIG5, FIG7, FIG9 and FIG11, one of the first directional member 41 and the second directional member 42 is provided with a first magnetic member 61, and the other of the two is provided with a second magnetic member 62.

[0099] The first magnetic attractor 61 attracts the second magnetic attractor 62 to generate a restraining force that prevents the cross-belt body 2 from deviating from the holding area 40.

[0100] Using the first magnetic chuck 61 and / or the second magnetic chuck 62, the crossband 2 can be precisely guided into the holding area 40 by magnetic constraint. The magnetic constraint can effectively prevent the crossband 2 from deviating from the set holding area 40 during placement, improving safety. Moreover, the magnetic force acts relatively smoothly and is not subject to the impact of instantaneous external force like mechanical locking, which can effectively reduce the negative impact caused by vibration.

[0101] Furthermore, the first magnetic attractor 61 includes a first magnet or magnetic metal, and the second magnetic attractor 62 includes a second magnet;

[0102] The contact surfaces of the first magnet and the second magnet are arranged with opposite polarities.

[0103] The magnetic metal can be iron, nickel, or cobalt; however, there are no restrictions on the specific type of magnetic metal.

[0104] That is, one of the contact surfaces between the first magnet and the second magnet is the N pole and the other is the S pole. Through the adsorption of the N pole and the S pole, the first orientation member 41 and the second orientation member 42 can be detachably connected. It can also maintain the orientation of the cross belt body 2 to a certain extent. Specifically, it can be the orientation of the free end 21 or the orientation of the front and back surfaces of the cross belt body 2.

[0105] Furthermore, the first magnet includes one or more sub-magnets, that is, the first magnetic attractor 61 may include one or more sub-magnets;

[0106] Multiple sub-magnets are arranged at certain intervals along the length of the cross-belt body 2.

[0107] Multiple sub-magnets are arranged at equal intervals along the length of the crossband 2, which makes the magnetic force distribution more uniform and avoids the situation where the local magnetic field generated by a single magnet is too strong or too weak. The uniform magnetic field makes the crossband 2 subjected to more consistent force during placement, which makes it easier to adjust the placement shape of the crossband 2 more accurately.

[0108] When the cross-belt body 2 is subjected to balanced constraints under the action of multiple sub-magnets, it is easier to maintain the straight placement of the cross-belt body 2 and reduce the offset or deformation caused by external force interference.

[0109] This application also provides a safety seat with a cross-strap orientation retention function, including the aforementioned device with a cross-strap orientation retention function.

[0110] The embodiments of this application have at least the following beneficial effects:

[0111] This application provides a device and a car seat with a lap belt orientation retention function. The free end 21 of the lap belt can be effectively oriented and retained, avoiding the lap belt from tilting randomly, reducing the possibility of the lap belt buckle 1 injuring the child, and further improving the safety performance of the lap belt.

[0112] Specifically, the seat frame 3 is provided with a first directional member 41 to form a holding area 40 for holding the crossbody belt 2, and the crossbody belt 2 is also provided with a second directional member 42. Through the cooperation of the first directional member 41 and the second directional member 42, the crossbody belt 2 can be held relatively stably in the holding area 40.
