Description

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a vehicle safety system and, more particularly, to a vehicle safety system that helps to prevent a child from mistakenly being left behind in an unattended vehicle thereby helping to also prevent the accidental death of the child.

2. Description of the Related Art

Several designs for vehicle safety systems have been designed in the past. None of them, however, include a vehicle safety system that uses a weight sensor in a child car seat that can communicate with an onboard vehicle computer to send a message to a mobile telephone.

Applicant believes that a related reference corresponds to U.S. Pat. No. 10,196,036 for a safety system for a vehicle that uses a pressure sensor on a vehicle seat and a mobile phone app. Applicant believes another related reference corresponds to U.S. Pat. No. 10,071,654 for an alarm system to prevent a child from being left in a vehicle which uses a weight sensor and a communication link to a cellular phone. None of these references, however, teach of a vehicle safety system that makes use of an onboard vehicle computer or a vehicle's engine control unit (ECU) and of the onboard diagnostics (OBD) to allow for the present invention to be retrofitted onto existing vehicles.

Other documents describing the closest subject matter provide for a number of more or less complicated features that fail to solve the problem in an efficient and economical way. None of these patents suggest the novel features of the present invention.

DETAILED DESCRIPTION OF THE EMBODIMENTS OF THE INVENTION

Referring now to the drawings, where the present invention is generally referred to with numeral 10, it can be observed that it, a vehicle safety system, basically includes a vehicle assembly 20, a communication assembly 40 and a seat assembly 60.

The present invention is depicted in an operational setting as seen in FIG. 1. It can be seen that the present invention helps to increase the safety of a child C by reducing the chances that child C gets mistakenly left behind in a car. This is a situation that may potentially be fatal to the child and as such it may be desired to prevent.

The present invention includes vehicle assembly 20. Vehicle assembly 20 may include a vehicle 22. Vehicle 22 may be one of any preexisting vehicles. Importantly, vehicle 22 may include an onboard vehicle computer 24 which may permit for wireless communication to occur to allow a user U to be alerted about situations occurring within vehicle 22 that may be dangerous or potentially fatal. Importantly, vehicle 22 may include a diagnostics port 26 which may allow for communication assembly 40 to be mounted thereto. Diagnostics port 26 may be the port used to connect onboard diagnostic tools as known in the art. In one embodiment, vehicle 22 may include a display device, which may be used for alerts or alarms in a visual manner. Vehicle 22 may also include speakers for audio alerts or alarms. Additionally, vehicle 22 may include vehicle seats 28 for sitting or placing objects thereon.

Vehicle safety system 10 may further include communication assembly 40. Communication assembly 40 may include a communication device 42. As seen in FIG. 3, communication device 42 may be connected or plugged to diagnostics port 26. Communication device 42 may include a housing 44. In one embodiment, housing 44 may preferably be made of plastic. In one embodiment, housing 44 may be semicircular. However, it should be understood that it might be suitable for housing to be virtually any other shape. It may be suitable for housing 44 to be of predetermined dimensions that cooperate with fitting within vehicle 22 and attaching to diagnostics port 26. On one side of housing 44 may be vehicle connectors 46 which may extend from housing 44. Vehicle connectors 46 allow for communication device 42 to be mounted inside of vehicle 22 to diagnostics port 26. Vehicle connectors 46 cooperate with and plug into diagnostics port 26. Inside of housing 44 may be a microprocessor 48 and a wireless communications module 52. Microprocessor 48 and wireless communications module 52 may allow for the present invention to communicate with a mobile device 82 of user U. Once the present invention detects that child C has been left unattended in vehicle 22 microprocessor 48 may use wireless communication module 52 to communicate with mobile device 82 in the form of a phone call, text message, mobile device notification, mobile application alert, an alarm or combinations thereof. Wireless communication module 52 may allow for communication to occur through Bluetooth, Wi-Fi, RFID, 2G, 4G, 5G, mobile data or the like as known in the art with mobile device 82.

Vehicle safety system 10 may further include seat assembly 60. As seen in FIG. 4, seat assembly 60 may preferably be mounted inside of vehicle 22 where child C is intended to sit. Seat assembly 60 may include a seat cushion 62. Seat cushion 62 may be where child C sits while in vehicle 22. In one embodiment, seat cushion 62 may have a rectangular shape. However, it should be understood that seat cushion 62 may be any predetermined shape of predetermined dimensions. It should be understood that seat cushion 62 may be made of a material that is comfortable to sit upon for prolonged periods of time. Seat cushion 62 may be made of cotton, foam, rubber, latex, memory foam, feathers, bamboo, polyester, torn material or other suitable materials. Seat cushion 62 may be placed on one of vehicle seats 28 where it is suitable for child C to be seated within vehicle 22. This may be on vehicle seats 28 at the front or rear of vehicle 22. Importantly, within seat cushion 22 may be a weight sensor 64. Inside of seat cushion 62 may be a microprocessor 48 having wireless communication module 52. This allows for data from weight sensor 64 to be communicated to user U wirelessly as well as for alerts and alarms to be triggered when needed. It may also be suitable for weight sensor 64 to be on a top surface or bottom surface of seat cushion 62. Weight sensor 64 may be adapted to detect if there is any weight on seat cushion 62. Weight sensor 64 may detect if child C is sitting on seat cushion 62. Weight sensor 64 may be set to have a predetermined threshold to determine when an alert is necessary. It may be necessary to shut vehicle 22 off before weight sensor 64 determines if child C is still within vehicle 22. Once vehicle 22 is shut down, if weight sensor 64 detects weight above the predetermined threshold then alerts or alarms may go off within vehicle 22 and may additionally be sent to user U, whom may be the caregiver of child C. The alerts and alarms may be possible due to vehicle assembly 20 and communication assembly 40. If vehicle 22 is shut off and weight sensor 64 detects weigh below the predetermined threshold then no alerts or alarms are necessary and it is assumed child C has not been left unattended within vehicle 22. In one embodiment, the present invention may activate necessary alerts or alarms after a predetermined time has lapsed since vehicle 22 has been turned off and child C is determined to be on seat cushion 62 by weight sensor 64. This allows for the safety of child C to increase and thereby reducing the chance of accidental death of child C. Communication device 42 and seat cushion 62 may be portable. It should be understood that the present invention may be retrofitted onto any vehicles having diagnostics port 26 typically used of onboard diagnostic tools to be plugged into. It can be appreciated that alerts and alarms generated by the present invention may be visual or audio or combinations thereof.

The foregoing description conveys the best understanding of the objectives and advantages of the present invention. Different embodiments may be made of the inventive concept of this invention. It is to be understood that all matter disclosed herein is to be interpreted merely as illustrative, and not in a limiting sense.
