Patent Application
20250033537
This application relates to a safety system for a vehicle seat. More particularly, the safety system actuates and monitors attachments for a child seat or other removable item in the vehicle to simplify and ensure safe and secured installation.
Generally described, a variety of forward and rearward facing child seats can be installed in a vehicle. More specifically, latches and tethers on a vehicle seat can be configured to secure the child seat in place. Many countries around the world have standardized how a child seat is to be secured to a vehicle seat and how movement of the car seat is controlled in the event of an impact to improve the overall safety of children's car seats in vehicles. In the U.S., the interconnection of the child seat to the vehicle seat employs a system called Lower Anchors and Tethers for Children (LATCH). LATCH employs two lower anchor attachments and a top tether. In Europe, a similar system for interconnecting the child seat to the vehicle seat is called ISOFIX.
Although current interconnection systems are well designed on paper, the level of safety provided by the systems is heavily dependent on whether the child seat is properly installed in the vehicle and whether the proper installation is maintained over time. Child seat installation is often physically difficult and can be confusing for users. Studies show that a high rate of mis-installation exists with child seats in vehicles. There is a need to improve the interconnection between the child seat and the vehicle to improve the level of safety provided to the child in the event of an impact.

The present disclosure is described with reference to the accompanying drawings, in which like reference characters reference like elements, and wherein:
Generally described, one or more aspects of the present disclosure relate to safety systems for vehicles. In certain embodiments, the disclosure relates to an attachment system that can be configured and arranged to connect to a variety of removable items (e.g. luggage, groceries, electronics, etc.) to enable an removable item or a passenger to be conveniently and securely attached to a vehicle.
Embodiments of the present disclosure can secure apparatus designed for children, generally referred to as child seats or child safety systems. Illustratively, such child seats or child safety systems can include a variety of apparatus/systems, including rear-facing car seats (e.g., Infant Car Seats, Convertible Seats, and All-in-One Seats) and forward-facing car seats (e.g., Convertible Seats, Combination Seats, and All-in-One Seats). Many jurisdictions/regions have laws, regulations or administrative procedures in which safety systems must be incorporated into a vehicle based on the age, height, weight, or combination of individual passengers. For example, most jurisdictions have laws requiring certified safety seats/systems for usually infants or children under or around the age of 8 that are passengers in a vehicle.
Prior approaches include anchors in conformance with regulatory standards on a vehicle seat that are fixed in positions. Installation of child seats on such fixed anchors can often be insecure or incorrect. Other approaches include safety systems that have to be mounted on a vehicle seat to receive a child seat. Such safety systems further obfuscate the latching mechanisms and often requires semi-permanent installation of the system on a vehicle seat and dedicating the seat position to the use of a specific child seat.
Advantages of the child seat attachment system can include ease of use. For example, the system can include self-presenting attachments (e.g., anchors) and confirm correct fit and safety. In certain embodiments, the child seat attachment system removes the need for a child seat base. In this way, the system can off-load the weight and cost of the child seat base to be instead incorporated into the vehicle seat. The system can confirm correct use including, in certain embodiments, electromechanical verification, child seat to vehicle verification, child to child seat verification, and/or child status. In certain embodiments, the system can monitor the child (e.g., heart rate, moisture, and/or picture of face).
The child seat attachment system can include one or more anchors that can be moved between a retracted position and an extended position to enable convenient and secured attachment of a child seat. In certain embodiments, an actuator is configured to move the one or more anchors between the retracted position and the extended position.
In certain embodiments, the child seat is attached to a rear seat (e.g., a seat and a seatback) of the vehicle. In certain embodiments, the one or more lower anchors can be disposed in a gap or slot between the seat and the seatback of the rear seat. In certain other embodiments, the one or more lower anchors can be disposed in the seat of the rear seat so as to be accessible by the user at least when in the extended position.
In certain embodiments, one or more of the anchors are configured as a tether anchor. In certain embodiments, the tether anchor is configured to secure a top tether extending from the child seat.
In certain embodiments, the system can include a switch. In certain embodiments, the switch can be activated by a user or by other means to cause the one or more anchors to move between the extended and retracted positions.
In certain embodiments, the child seat attachment system can include a controller that is configured to move the one or more anchors between the retracted position and the extended position to ease engagement of the one or more anchors to the attachment parts on the child seat (e.g. hooks). In certain embodiments, after engaging the hooks or another kind of attachment parts of the child seat, the controller can further move the one or more anchors along with the engaged hooks or another kind of attachment parts of the child seat towards the retracted position so as to firmly secure the child seat to the vehicle. In certain embodiments, the controller moves the anchors based at least in part on a trigger signal. Such trigger signal can be provided by a trigger source, for example, a smartphone, the vehicle, or the child seat itself.
In certain embodiments, the child seat attachment system can further include a power and/or data connection configured to connect to the child seat. In some embodiments, information generated from various sensors, cameras, integrated components, etc., can be provided to a processing component via a power and/or data connection. Illustratively, such a processing component, such as in the child safety system or vehicle, can process attributable to various conditions (e.g. temperature, dampness, etc.) of the child seat. In certain embodiments, the processing component can further transmit and provide the processed information to the vehicle, a user, or an owner of the vehicle through wire or wirelessly.
In certain embodiments, the system can comprise one or more sensors configured to sense tension applied on the one or more anchors when the one or more anchors are engaged to the hooks or another kind of attachment part of the child seat. In certain embodiments, the controller can receive tension information from the sensor and determine, periodically or continually, whether the one or more anchors are experiencing a sufficient level of tension that maintains the child seat firmly against the seat. For example, in certain embodiments, the controller can further retract the one or more anchors (along with the engaged hook) even after the initial installation of the car seat based on the sensed tension. The further retraction of the one or more anchors can increase the tension to a level which sufficiently secures the child seat to the vehicle.
In certain embodiments, the controller can be configured to generate a status signal (numeric value, level, color code, etc.) indicative of the real time tension and provide the status signal to the vehicle, the user, an owner of the vehicle, and the like. The user or owner of the vehicle can then act, based on the status signal, to make sure that the child seat is securely attached to the vehicle.
The system 1 comprises one or more anchors 10. In certain embodiments, the one or more anchors 10 comprise a first lower anchor 10A and a second lower anchor 10B. In certain embodiments, the first lower anchor 10A and the second lower anchor 10B move between a retracted position 2 and an extended position 3 and can stay at any point between the retracted position 2 and the extended position 3.
As shown in
As shown in
In certain embodiments, the system 1 can include a controller 30. In certain embodiments, the controller 30 is configured to move at least one of the lower anchors 10A, 10B between the retracted position 2 and the extended position 3. In certain embodiments, the controller 30 can be configured to receive a trigger signal 31. In certain embodiments, the trigger signal 31 is provided by a signal source 32. In certain embodiments, the controller 30 moves at least one of the lower anchors 10A, 10B between the retracted position 2 and the extended position 3 in response to receiving the trigger signal 31 from the signal source 32. In certain embodiments, the signal source 32 can be a smartphone or smart device, input components associated with the vehicle (e.g., touch screen interfaces, microphones, vision system, pressure sensing system, etc.), or the child seat 103 itself. In some embodiments, for example, as a user is approaching a vehicle implementing the system 1 with a child seat 103, the controller 30 may receive a trigger signal 31 from a signal source 32 (e.g., a smartphone connected to the child seat or the child seat itself) through Bluetooth® or other wireless means. Upon receiving the trigger signal 31, the controller 30 may control the actuator 20 to move at least one of the lower anchors 10A, 10B from the retracted position 2 to the extended position 3. The controller 30 can control the anchors 10A, 10B to automatically extend such that the anchors 10A, 10B are ready for attachment of the child seat 103 by the time the user opens the vehicle door.
In certain embodiments, the system 1 can further include one or more sensors 40. The one or more sensors 40 can include image sensors, temperature sensors, humidity sensors, or any other sensors. The controller 30 can receive information from the one or more sensors 40 and transmit the information to a processing component 60 for processing or directly to a user or an external device for monitoring/processing. In certain embodiments, for example, the controller 30 can receive video data from an image sensor and transmit the video data to a smart device in real-time or periodically so that a user can monitor a child's status in the child seat 103 of the system 1. In certain embodiment, the one or more sensors 40 can be configured to sense tension between the one or more anchors 10 and the child seat 103. For example, in certain embodiments, the controller 30 receives tension information from the sensor 40. In certain embodiments, the controller 30 can further determine whether the one or more anchors 10 are tightly attached to the hooks or another kind of attachment part of the child seat 103. In certain embodiments, the controller 30 can be configured to determine the tightness (e.g., tension) of the attachment between the child seat 103 and the vehicle seat 100 on a periodic or continual basis. In certain embodiments, the tightness is determined in real time.
In certain embodiments, the controller 30 can further generate a status signal indicative of the tightness or completeness of the attachment. In some embodiments, the child seat attachment system 1 can include LED illumination configured to indicate whether the child seat 103 has been securely attached. For example, as shown in
In certain embodiments, the controller 30 is configured to further retract the anchors 10 and tighten the attachment (e.g., increase tension) between the child seat 103 and the vehicle seat 100 based on the tension sensed by the one or more sensors 40. In certain embodiments, the controller 30 is configured to generate a status signal indicative of the tension. The status signal can be provided to the vehicle, or to a user or owner of the vehicle.
In certain embodiments, the system 1 can further include a processing component 60 configured to connect to the child seat 103. One or mor processing components can receive or measure data provided through power and/or data connection to monitor various conditions (e.g. temperature, dampness, etc.) of the child seat 103 or determine operational parameters associated with use of the system 1. In certain embodiments, condition information can be collected by one or more sensors and/or cameras. In some embodiments, the processing component 60 can be wired or wireless, thereby enabling the condition information to be transmitted to, for example, a smartphone, the vehicle, or a user or owner of the vehicle. In certain embodiments, the processing component 60 connects to the controller 30. In certain embodiments, the processing component 60 is a separate unit.
In certain embodiments, the one or more anchors 10 can include a tether anchor configured to secure a strap extending from the child seat 103.
In certain embodiments, each of the one or more anchors can alternatively be straight wires allowing the anchors to extend and retract along a straight axis. A child seat attachment system employing straight anchors can include a linear actuation system. In some embodiments, the linear actuation system can be positioned behind a vehicle seat instead of below the seat. The system with the linear system may be more suitable for two seats vehicles with nonmoving seats.
In accordance with various embodiments, an attachment system disclosed herein can also be used to secure other removable items. For example, the attachment system can be used to secure a console with various functions (e.g., bag storage, cup holders, table that could unfolds onto adjacent seats, and etc.). The attachment system can also be used to secure a food delivery storage box with optional heating or cooling function. It can be advantageous to also secure a pet carrier using the attachment system disclosure herein. Further, the attachment system can also be used to secure an electric device, for example, an Optimus bipedal bot, to avoid the need for other complicated securing method (e.g., seatbelt) and provide charging function.
The process 200 may be implemented for each individual actuator 20, such as by the controller 30 configured to receive or provide information on each individual actuator 20 and determine operational parameters for each individual actuator 20. Alternatively, the process 200 may be implemented for a set of actuators 20 located on the vehicle.
At block 202, the controller 30 receives a trigger signal from a smartphone, one or more components of the vehicle, or the child seat 103. For example, in certain embodiments, the vehicle may detect that a child seat 103 is placed on a vehicle seat 100 and send a trigger signal to the controller 30. In other embodiments, the vehicle may detect a user's verbal cue declaring a desire to mount a child seat 103 and send a trigger signal to the controller 30. At block 204, the controller 30 activates the actuator 20 to move anchors 10 from the retracted position 2 to the extended position 3 upon receiving the trigger signal. In the extended position 3, the anchors 10 are ready to be engaged with hooks or another kind of attachment part on the child seat 103. At block 206, the controller 30 determines whether the anchors 10 are engaged with the hooks or another kind of attachment part on the child seat 103. If the controller 30 determines the answer to be yes, the process moves to block 208 where controller 30 can activate the actuator to move the anchors 10 along with the hooks or another kind of attachment part on the child seat 103 towards the retracted position 2 so as to secure the child seat 103 to the vehicle seat 100. If the controller 30 determines the answer to be no, the process returns to block 204 where the engagement process can be repeated.
At block 210, the controller 30 can measure the tension on the anchor 10 when the anchor 10 is engaged to one of the hooks or another type of attachment part on the child seat 103. In certain embodiments, the tension is sensed by the sensor 40. In certain embodiments, the controller 30 receives the tension information from the sensor 40.
At block 212, the controller 30 determines whether the tension meets a predetermined requirement or value. The predetermined requirement or value can be based on a level of tensions that is sufficient for the child seat 103 to be safely installed to the seat 100. If the tension meets the predetermined requirement or value, the process then moves to block 214.
In certain embodiments, at block 214, the controller 30 can generate a status signal indicative of the sensed tension. In certain embodiments, the status signal can be provided to the vehicle, a user, or an owner of the vehicle. A user receiving the status signal will be able to monitor the sensed tension and take remedial steps if the tension falls below a predefined safe value. The process can then return to block 210.
Returning to decision block 212, if the controller 30 determines that the anchors 10 are not tightly attached to the hooks or another kind of attachment part of the child seat 103, the process can return to block 208 where the controller 30 can activate the actuator 20 to further move the anchors 10 towards the retracted position 2 and increase the tension. This feature can ensure that the child seat 103 is tightly secured to the vehicle seat 100 without user's input.
In certain embodiments, the controller 30 can be configured to periodically determine whether the anchors 10 are tightly attached to the hooks or another kind of attachment part of the child seat 103. Alternatively, the controller 30 can be configured to continually determine whether the anchors 10 are tightly attached to the hooks or another kind of attachment part of the child seat 103.
In accordance with various embodiments disclosed herein, another embodiment of a process conducted by the controller 30 of the child seat attachment system 1 may not perform any one or all of blocks 210 to 214 above. The anchors 10 may, after being moved to the retracted position 2, simply stay locked in the retracted position 2 until receiving a trigger signal to go through the process containing block 202, 204, 206, and 208 again as described above.
