Safety sheet

Abstract

The safety seat includes a seat section, an anchor device, two movable side protection blocks, a side protection block driving module, an anchor device sensor, and a control module. The anchor device sensor is provided adjacent to the anchor device. The side protection block driving module is connected to the side protection block and drives the side protection block to fold or unfold. The control module is electrically connected to the anchor device sensor and the side protection block driving module and detects whether the seat section is occupied. When the control module detects that the anchor device is in a locked state via the anchor device sensor and that the seat section is occupied, the control module controls the side protection block driving module to unfold at least one of the side protection blocks, thereby enhancing the side impact protection capability of the safety seat.

Description

Technical Field

[0001] The present disclosure relates to a safety seat, particularly to a safety seat having a side protection function.

Background Art

[0002] Conventionally, in consideration of a safe and comfortable riding space, it has been actively carried out to provide a safety seat for carrying a child. A safety seat is a device that restrains a child with a restraint device. During a sudden braking or accidental collision of a vehicle, the safety seat decelerates the impact force applied to the child through its housing and restricts the movement of the child by its restraint device, thereby reducing the injury of the child in case of an accident and ensuring the safety of the child sitting in the vehicle. Among safety seats, some have side protection blocks on both sides thereof for side collision protection. Among the side protection blocks, some are foldable in order to reduce the occupied space of the safety seat. Among these side protection blocks, some side protection blocks can be manually deployed, so the user needs to actively open the side protection blocks. However, if the user forgets to deploy the side protection blocks, the side protection function of the side protection blocks may be lost, and the height may be significantly reduced.

Summary of the Invention

[0003] In order to supplement the deficiencies of the prior art, the technical problem to be solved by the present disclosure is to provide a safety seat that can automatically deploy the side protection blocks to be protruded and generate a side protection effect when it senses that the safety seat is occupied after the safety seat is attached to a vehicle seat.

[0004] According to one embodiment of the present disclosure, the safety seat includes a seat portion, an anchoring device (which may also be called a “fixing device”), two movable side protection blocks, a side protection block drive module, an anchoring device sensor, and a control module. The anchoring device sensor is provided adjacent to the anchoring device. The side protection block drive module is connected to the side protection blocks and drives them to fold or unfold. The control module is electrically connected to the anchoring device sensor and the side protection block drive module and detects whether the seat portion is occupied. If the control module detects via the anchoring device sensor that the anchoring device is locked and the seat portion is occupied, it controls the side protection block drive module to unfold at least one of the side protection blocks, thereby enhancing the side impact protection capability of the safety seat. Thus, the side protection blocks can be automatically unfolded without user (parent or driver, etc.) operation, effectively solving the problem that the side protection function of the side protection blocks may be disabled or significantly reduced due to user negligence.

[0005] The merits and spirit of this disclosure can be further understood from the following detailed description and accompanying drawings of this disclosure. [Brief explanation of the drawing]

[0007] Referring to Figures 1 and 2, the safety seat 1 according to an embodiment of the present disclosure includes a seat body 12, two anchoring devices 14, two movable side protection blocks 17, and a fastening assembly 18. The seat body 12 is locked to an anchoring structure provided on the vehicle seat via the anchoring devices 14 for attaching the safety seat 1 to the vehicle seat. The side protection blocks 17 are movably positioned on the seat body 12. The side protection blocks 17 can be deployed to project outward relative to the seat body 12 to provide a side protection effect, and the side protection blocks 17 may be folded to facilitate storage of the safety seat 1. The fastening assembly 18 is movably positioned on the seat portion 122 of the seat body 12 and is detachably connected to a safety belt so that a child seated on the seat portion 122 can be securely fastened to the safety seat 1 by the safety belt.

[0008] The safety seat 1 according to this embodiment further comprises a control circuit 10 including a control module 20, an anchor device sensor 22, and a side protection block drive module 24. The control module 20 is electrically connected to the anchor device sensor 22 and the side protection block drive module 24, respectively. The anchor device sensor 22 is located adjacent to the anchor device 14. The side protection block drive module 24 is connected to the side protection block 17 and drives the side protection block to fold or unfold. The control module 20 can sense the state of the anchor device 14 via the anchor device sensor 22. When the control module 20 senses from the anchor device sensor 22 that the anchor device 14 is locked and the seat portion 122 is occupied, it controls the side protection block drive module 24 to unfold at least one of the side protection blocks 17, thereby providing side impact protection to the safety seat 1.

[0009] Referring further to Figures 3 to 6, in this embodiment, the anchor device 14 includes a structural frame 142, an anchor hook 144, and an operating element 146. The anchor hook 144 is rotatably connected to the structural frame 142 and has a pivot axis 144a (shown as a cross in Figures 4 and 6, and as a dashed line in Figure 5), and is rotatable relative to the structural frame 142 about the pivot axis 144a, and is positioned in a locked position (shown in Figure 4) and an unlocked position (shown in Figure 6). The anchor device 14 is in a locked state (as shown in Figure 4) when the anchor hook 144 is in the locked position, and in principle, the anchor device 14 can engage with the anchor structure, shown by the thick dashed line in Figure 4, such that, for example, the anchor hook 144 hooks onto the crossbar of the anchor structure, and the safety seat 1 is securely attached to the vehicle seat. When the anchor hook 144 rotates to the unlocked position, the anchor device 14 detaches from the anchor structure, and the safety seat 1 can be removed from the vehicle seat.

[0010] The operating element 146 is slidably positioned relative to the structural frame 142 in the sliding direction 146a (indicated by a double arrow) and has a restraining portion 1462, the sliding direction 146a being perpendicular to the rotation axis 144a. The restraining portion 1462 is capable of restraining the rotation of the anchor hook 144, for example, it can limit or prevent the rotation of the anchor hook 144. In this embodiment, the restraining portion 1462 is plate-shaped, and when the anchor hook 144 is in the locked position, the restraining portion 1462 engages (e.g., clamps) with the clamp slot 144b of the anchor hook 144 to prevent the rotation of the anchor hook 144. Furthermore, a restoring spring 148 biasing between the operating element 146 and the structural frame 142 is used in the anchor device 14 to slide the operating element 146 toward the anchor hook 144, thereby facilitating the maintenance of the restraining portion 1462 in a clamped state in the clamp slot 144b. Furthermore, the operating element 146 has an exposed operating section 1466, which can be moved by a user (e.g., a parent or driver) in the sliding direction 146a, for example, to disengage the restraining section 1462 from the clamp slot 144b, thereby rotating the anchor hook 144 toward the unlocked position under the bias of the torsion spring 150, i.e., the anchor hook 144 is always biased toward the unlocked position. Furthermore, when the anchor hook 144 is in the unlocked position, i.e., when the anchor device 14 is in the unlocked state, the anchor hook 144 is held in the unlocked position under the bias of the torsion spring 150.

[0011] Furthermore, in this embodiment, the anchor device 14 is provided with a safety lock mechanism for the operating element 146 to prevent the restraining portion 1462 from detaching from the clamp slot 144b in the event of unexpected slippage of the operating element 146 due to vibrations generated during operation, or if the anchor function of the anchor device 14 fails due to unexpected slippage of the operating element 146 by the user. The safety lock mechanism includes a release element 152, a movable pin 154, and a stopper 156. The release element 152 is slidably positioned on the structural frame 142. The movable pin 154 is slidably positioned in the sliding direction 154a (indicated by a double arrow) within the sliding groove 1468 of the operating element 146. The stopper 156 is fixed on the structural frame 142 to prevent the movable pin 154 from moving in the sliding direction 146a, thereby preventing the operating element 146 from accidentally moving in the sliding direction 146a. The unlocking element 152 can move the movable pin 154 along the inclined surface 152a (i.e., slide it relative to the operating element 146 in the sliding direction 154a) so that the movable pin 154 does not structurally interfere with the stopper 156 in the sliding direction 146a (i.e., release the operating element 146), and as a result the operating element 146 moves smoothly in the sliding direction 146a. The stopper 156 can selectively stop the movable pin 154 as long as the sliding direction 154a is not parallel to the sliding direction 146a. In actual operation, the user can move the unlocking element 152 to release the operating element 146, and then move, for example, the operating part 1466 of the operating element 146 to disengage the restraining part 1462 from the clamp slot 144b of the anchor hook 144. At this time, the anchor hook 144 rotates to the unlocked position due to the bias of the torsion spring 150, so that the anchor device 14 is detached from the anchor structure. Furthermore, a restoring spring 158 that contacts the unlocking element 152 and the stopper 156 is used in the safety locking mechanism to disengage the inclined surface 152a of the unlocking element 152 from the movable pin 154, and a torsion spring 160 provided on the operating element 146 is used in the safety locking mechanism to return the movable pin 154 to its original position, i.e., to cause the stopper 156 to stop the movable pin 154 again.

[0012] Furthermore, in this embodiment, the operating element 146 also has a sensing unit 1464, the projection position of which is indicated by a dotted circle in Figures 4 and 6. The sensing unit 1464 can slide together with the operating element 146 to trigger the anchor device sensor 22, and the control module 20 senses the state of the anchor device 14 via the anchor device sensor 22. In this embodiment, the anchor device sensor 22 may be a limit switch, and the sensing unit 1464 triggers the anchor device sensor 22 by pressing the actuator of the limit switch. Thus, when the anchor device 14 is in a locked state, i.e., when the anchor hook 144 is in the locked position, the restraining unit 1462 restrains the rotation of the anchor hook 144, and the sensing unit 1464 triggers the anchor device sensor 22. In practical applications, the anchor device sensor 22 may be a proximity sensor or other sensor capable of sensing the position of the sensing unit 1464. As another example, the anchor device sensor 22 may be a pair of contacts, and it can be logically considered that the anchor device sensor 22 is triggered when the sensing unit 1464 conducts through the contacts. In practical applications, the anchor device sensor 22 may also be directly triggered by the anchor hook 144. Furthermore, in practical applications, the anchor device sensor 22 may be structurally integrated with the anchor device 14. For example, the anchor device sensor 22 may be fixed onto the structural frame 142 of the anchor device 14, and the casing may cover both the anchor device sensor 22 and the anchor device 14, thereby preventing external objects from interfering with the operation of the anchor device sensor 22, for example, preventing an external object from inadvertently triggering the anchor device sensor 22 and causing a misjudgment by the control module 20.

[0013] Referring to FIGS. 1, 2, 7 to 9, in this embodiment, the side protection block 17 is rotatably connected to the fixed sheet 126 of the seat body 12. The side protection block drive module 24 is connected to the side protection block 17 via two drive mechanisms 240, and the two drive mechanisms 240 are respectively arranged corresponding to the side protection block 17. The drive mechanism 240 includes a motor 242 and a gear set 244. The motor 242 (for example, a servo motor) is provided on the fixed sheet 126. The motor 242 is coupled to the corresponding side protection block 17 via the gear set 244. Therefore, the control module 20 controls the side protection block drive module 24 to control the operation of the motor 242, and thus drives the corresponding side protection block 17 via the gear set 244, so that the corresponding side protection block 17 can protrude relatively outward with respect to the seat body 12, or the corresponding side protection block 17 can be folded.

[0014] The fixed seat 126 has a lock groove 1262. The side protection block 17 includes a housing 172, a lock block 174, and a bias spring 176. The housing 172 is rotatably connected to the fixed seat 126. The lock block 174 is slidably positioned within the housing 172. The bias spring 176 abuts against the lock block 174 to drive the lock block 174 toward the lock groove 1262. The gear set 244 includes, but is not limited to, a drive gear 2442, a clutch gear 2444, and a driven gear 2446. The motor 242 can mesh with the drive gear 2442 via a pinion 242a. The drive gear 2442 and the clutch gear 2444 are coaxially positioned and detachably meshed in the axial direction 244a (shown by a dashed line in Figure 9). The drive gear 2442 and the clutch gear 2444 are detachably meshed with each other via wavy teeth 2442a and 2444a projecting parallel to the axial direction 244a, and the drive gear 2442 and the clutch gear 2444 slide relative to each other via the wavy teeth 2442a and 2444a to detachably mesh with each other. The clutch gear 2444 meshes with a driven gear 2446. The driven gear 2446 is connected to a linkage rod 174a fixed to the lock block 174. Thus, the motor 242 can drive the side protection block 17 to rotate relative to the seat body 12 via the gear set 244 and the linkage rod 174a. Furthermore, in this embodiment, the gear set 244 includes a restoring spring 2448 that contacts the clutch gear 2444 to drive the drive gear 2442 to mesh with the clutch gear 2444. The detachable meshing of the drive gear 2442 and the clutch gear 2444 prevents the motor 242 from losing step and prevents the side protection block 17 from being detached from the motor 242 when interference occurs. In actual applications, the return spring 2448 can also be positioned to the side of the drive gear 2442 so as to mesh the drive gear 2442 with the clutch gear 2444 and to contact the drive gear 2442. This structural configuration can also provide the effect of preventing the motor 242 from losing step.A person skilled in the art can understand that this embodiment provides a design having a gear set 244, but the present disclosure is not limited thereto. Even if it is a design different from the gear set 244, as long as the effects of the present disclosure can be achieved, it should be covered by the present disclosure.

[0015] Furthermore, referring to FIGS. 10 to 12, the driven gear 2446 drives the side protection block 17 to rotate from the folded position (which can also be called the "closed position" as shown in FIG. 10) to the deployed position (as shown in FIG. 11) with respect to the seat body 12 via the linkage rod 174a. During the rotation, the lock block 174 slides on the fixed seat 126. When the side protection block 17 is in the deployed position, the lock block 174 is aligned with the lock groove 1262. When the driven gear 2446 continues to rotate, the driven gear 2446 cooperates with the linkage rod 174a (lock block 174) to drive the lock block 174 to slide into the lock groove 1262 in a direction perpendicular to the axial direction 244a, and by locking the side protection block 17 (as shown in FIG. 12) and holding it in the deployed position, side impact protection can be effectively provided for the safety seat 1. The lock block 174 has an exposed operation portion 174b, and the user can slide the operation portion 174a to disengage the lock block 174 from the lock groove 1262.

[0016] Furthermore, referring to Figures 9, 13, and 14, in this embodiment, the corresponding drive mechanism 240 of the side protection block drive module 24 includes a toggle switch 246 (shown as shaded in Figures 13 and 14) located on the fixed sheet 126. The driven gear 2446 of the drive mechanism 240 has an arc-shaped groove 2446a, and the trigger portion of the toggle switch 246 is slidably positioned in the arc-shaped groove 2446a. When the side protection block 17 is in the folded position, the end 2446b of the arc-shaped groove 2446a toggles the trigger portion of the toggle switch 246 in one direction, and when the side protection block 17 is in the unfolded position and locked, the other end 2446c of the arc-shaped groove 2446a toggles the trigger portion of the toggle switch 246 in the other direction. In this way, the side protection block drive module 24 can determine the state of the side protection block 17 via the toggle switch 246 and correctly control the operation of the drive mechanism 240.

[0017] Referring to Figures 1, 2, and 15-17, in this embodiment, the clamping assembly 18 is movably projected onto the seat portion 122 of the safety seat 1, and the control circuit 10 further includes a position sensor 26 (shown as a diagonal line in Figure 2). The position sensor 26 is electrically connected to the control module 20 to sense changes in the position of the clamping assembly 18. In practical applications, when a child is sitting on the seat portion 122 of the safety seat 1, the child (e.g., their buttocks) generally presses against the clamping assembly 18, and the pressed clamping assembly 18 can be sensed by the position sensor 26. That is, in principle, if the control module 20 senses, via the position sensor 26, that the clamping assembly 18 has been pressed, the control module 20 can determine that a child is sitting on the seat portion 122.

[0018] In this embodiment, the fastening assembly 18 includes, for example, an actuation part 182, a rotating shaft part 184, and a fastening part 186. The fastening assembly 18 is rotatably connected to the seat part 122 via the rotating shaft part 184. The actuation part 182 extends upward and toward the backrest 124 and has an end connected to the rotating shaft part 184 (i.e., a connecting end) and the other end that is relatively higher than the rotating shaft part 184 (i.e., a free end). Relatively, the fastening part 186 extends upward and faces the backrest 124 and has an end connected to the rotating shaft part 184 (i.e., a connecting end) and the other end that is relatively higher than the connecting end (i.e., a free end), so that the fastening assembly 184 is integrally formed in a V shape. Furthermore, a fastener 1862 is provided at the free end of the fastening part 186. The rotating shaft portion 184 is rotatably connected to the sheet portion 122 via a rotatable shaft or pin, and the fastening assembly 18 is integrally formed as a seesaw structure so as to be rotatable relative to the sheet portion 122, so that the position sensor 26 can sense the change in position (or angle) of the fastening assembly 18 caused by the rotation, thereby determining whether the fastening assembly 18 is being pressed down. In a preferred embodiment, the position sensor 26 is located within the fastener 1862. In other embodiments, the position sensor 26 may also be located in the actuation portion 182 or the rotating shaft portion 184, and is not limited thereto. Furthermore, in a preferred embodiment, the position sensor 26 may be a gyroscope, but it will be understood by those skilled in the art that other types of position sensors, such as accelerometers, may be used instead of a gyroscope, and is not limited thereto.

[0019] Furthermore, the above description gives an example in which the position sensor 26 senses a change in the angle of the clamping assembly 18. In practical applications, the position sensor 26 can be implemented as a device that senses whether the clamping assembly 18 is in a pressed position (as shown in Figures 15 and 17). For example, a switch is used as the position sensor 26' (shown by a dotted line in Figures 16 and 17), which is located on the seat portion 122 and below the actuation portion 182 of the clamping assembly 18, so that the actuation portion 182 directly triggers the position sensor 26' when the clamping assembly 18 is in a pressed position. This structural configuration also has the function of sensing whether the clamping assembly 18 is being pressed. For example, the position sensor 26' may be a touch switch, an optical sensor, etc., and is not limited thereto in this disclosure.

[0020] Furthermore, in this embodiment, the fastening assembly 18 is integrally formed as a seesaw structure, and when the fastening assembly 18 is in the pressed position (for example, when the child is not sitting on the safety seat 1), the rotating shaft portion 184 rotates forward, so that the fastening portion 186 moves toward the front of the safety seat 1, avoiding interference with the parent moving the child to the seat portion 122 and making operation easier (for example, the parent does not need to operate the fastening portion 186 with one hand while holding the child on the seat portion 122). Moreover, in this embodiment, the rotating shaft portion 184 is biased by the torsion spring 27 and attempts to move to the non-pressed position, so the actuating portion 182 remains protruding relative to the seat portion 122, and the fastening portion 186 is in a position facing relatively forward. In practical applications, interlocking protrusions and recesses can also be arranged on the rotating shaft portion 184 and the seat portion 122 to maintain the fastening portion 186 in a position facing relatively forward, but a detailed explanation is omitted.

[0021] Furthermore, in this embodiment, the control module 20 senses the operating part 182 of the clamping assembly 18 via the position sensor 26 to determine whether the seat portion 122 is occupied or not. However, in actual applications, the control module 20 can also sense whether the seat portion 122 is occupied or not using a sensor provided independently of the clamping assembly 18. For example, this sensor may be a pressure sensor, a touch switch, a proximity sensor, etc., and this sensor is located on the seat portion 122 and is triggered when a child can sit on the seat portion 122.

[0022] Referring to Figure 18, this is a flowchart of the put-in-use safety seat 1. Therefore, for further explanation of the components of the safety seat 1, please refer to the relevant explanations and corresponding drawings above without further repetition. As shown in step S102 of Figure 18, the control module 20 senses the state of the anchor device 14 via the anchor device sensor 22 and determines whether the anchor device 14 is in a locked state. If "NO" (i.e., the anchor device is not in a locked state), the process returns to step S102. If "YES" (i.e., the anchor device is in a locked state), the control module 20 senses the state of the seat portion 122 via the position sensor 26 and determines whether the seat portion 122 is occupied (e.g., whether a child is sitting on the seat portion 122), as shown in step S104. If the answer is "NO" (i.e., the seat portion is not occupied), the process returns to step S104. If the answer is "YES" (i.e., the seat portion is occupied), the control module 20 controls the side protection block drive module 24 to deploy at least one of the side protection blocks 17 to enhance the side impact protection capability of the safety seat 1, as shown in step S106. The control module 20 then continuously senses the state of the seat portion 122 via the position sensor 26 to determine whether the seat portion 122 is occupied (for example, whether a child sitting on the seat portion 122 is still sitting on the seat portion 122), as shown in step S108. If the answer is "YES" (i.e., a child is still sitting on the seat portion 122 and is still pressing the actuation part 182 of the clamping assembly 18), the process returns to step S108. If "NO" (i.e., the child has moved away from the seat portion 122 and the actuation portion 182 of the clamping assembly 18 is no longer pressed and is protruding from the seat portion 122), the control module 20 controls the side protection block drive module 24 to fold the deployed side protection block 17, as shown in step S110.In step S106, the control module 20 may directly deploy the side protection blocks 17 on both sides, or it may decide which side protection blocks 17 to deploy or both depending on the set value. The set value may be set before or after the safety sheet 1 is installed (for example, after step S102, the user may be prompted to set the set value as described later).

[0023] Furthermore, in a preferred embodiment, the control circuit 10 further includes a communication module 28 electrically connected to the control module 20 (as shown in Figure 1). In some embodiments, the communication module 28 may be a Bluetooth module that can communicate with an external mobile device 5 via a Bluetooth transmission interface or an on-board control system 4 on the vehicle. In other embodiments, the communication module 28 may be a short-range communication module such as WiFi, ZigBee, or RFID. The setting procedure can be configured such that the control module 20 sends a request signal S1 to the on-board control system 4 or mobile device 5 and receives a setting signal S2 from the on-board control system 4 or mobile device 5 to complete the setting of the setting value. The on-board control system 4 and mobile device 5 can run corresponding mobile application programs, and the user, by operating the application program, selects one or both of the side protection blocks 17 to deploy, for example, needing to deploy the side protection block 17 near the vehicle door, and the on-board control system 4 and mobile device 5 send a setting signal S2 to the control module 20 according to the user's selection. In actual applications, the control module 20 can also be automatically configured to deploy the side protection blocks 17. For example, proximity sensors are provided on both sides of the seat body 12 corresponding to the side protection blocks 17 to detect whether or not it is close to a vehicle door. Therefore, the control module 20 can determine which side of the seat body 12 is closer to the vehicle door based on the detection by the proximity sensors and perform a set accordingly (i.e., designate the side protection block 17 located on the side of the seat body 12 closer to the vehicle door as the side protection block 17 that should be deployed).

[0024] As mentioned above, although the safety seat 1 has been described as having an integrated structure, a height-adjustable safety seat may also be used, and a detailed explanation is omitted. In practical terms, a composite type safety seat can also be used. For example, as shown in Figure 19, the safety seat 6 includes a base 61 and a basket 62, the basket 62 being detachably connected to the base 61. The seat portion 622 is located on the basket 62, and the side protection block 63 is rotatably connected to the basket 62. The base 61 is locked to an anchor structure provided on the vehicle seat via an anchor device 64 for attaching the safety seat 6 to the vehicle seat. The safety seat 6 also includes adjustable support legs 65 that support the base 61 in contact with the floor near the vehicle seat. A docking electrical connection interface can be placed between the basket 62 and the base 61, so that the control module can be smoothly electrically connected to the anchor device sensor, position sensor and drive mechanism, whether it is located on the base 61 or on the basket 62. For example, as shown in Figure 20, similar to the safety seat 6, the safety seat 7 includes a base 71 and a basket 72 (its outline is shown by a dotted line), the basket 72 being detachably connected to the base 71. A seat portion 722 is positioned on the basket 72, and side protection blocks 73 are rotatably connected to the base 71. The base 71 is locked to an anchor structure provided on the vehicle seat via an anchor device 74 for attaching the safety seat 7 to the vehicle seat. The safety seat 7 also includes adjustable support legs 75 that contact the floor near the vehicle seat and support the base 71. Similarly, a docking electrical connection interface may be positioned between the basket 72 and the base 71 to ensure smooth electrical connection with the anchor device sensor, position sensor, and drive mechanism, whether the control module is located on the base 71 or on the basket 72. Furthermore, if the basket 72 is separated from the base 71, logically, the child (or baby) would need to be away from the vehicle, and the side protection block 73 would no longer be needed, so the control module can fold up the deployed side protection block 73.Furthermore, the above explanation regarding the modification of safety sheet 1 can also be applied to the parts of safety sheets 6 and 7 for which detailed explanations are omitted.

[0025] As described above, after safety seats 1, 6, and 7 are fixed to the vehicle's anchor structure, the side protection blocks can be automatically deployed when a child is sitting in safety seats 1, 6, or 7, effectively solving the problem of users forgetting to deploy the side protection blocks and improving the inconvenience of users having to manually deploy or fold the side protection blocks. In addition, for practical purposes, safety seats 1, 6, and 7 can be equipped with energy storage devices (such as batteries) to supply the power required by the electronic devices installed in safety seats 1, 6, and 7, but a detailed explanation of this will be omitted.

[0026] The foregoing description represents only preferred embodiments of the Disclosure and is not intended to limit the Disclosure. To those skilled in the art, the Disclosure is modifiable and can be adapted. Modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the Disclosure shall be within the scope of the Disclosure. [Explanation of symbols]
