A safety belt automatic adjustment apparatus includes a safety belt buckle fastening assembly, a safety belt retractor and a linking component. The safety belt buckle fastening assembly is rotatably connected to a seat body of a child safety seat and for connecting with a safety belt buckle. The safety belt retractor is used for retracting a safety belt, and the safety belt retractor includes a restraining assembly for restraining a movement of the safety belt in a predetermined direction. The linking component is installed between the safety belt buckle fastening assembly and the safety belt retractor, and the safety belt buckle fastening assembly rotates to drive the linking component and the restraining assembly, so as to restrain or release the safety belt winding around the safety belt retractor. The safety belt automatic adjustment apparatus has advantages of automatic adjustment for the safety belt, simple structure, convenient operation and enhanced safety.

An apparatus and method for assisted buckle release employing a generally C-shaped or U-shaped assistive device adapted to depress a buckle's release button, such as a button typical of a child car seat restraint harness, and thereby assist in unlocking the buckle.

A detection system may include a first sleeve shaped to receive and retain a buckle of a child safety seat. The first sleeve may include a first body portion shaped to receive and retain the buckle, a male connector portion integrally formed with the first body portion, and a transmitter electrically coupled to the male connector portion. The detection system may include a second sleeve shaped to receive and retain a buckle connector. The second sleeve may include a second body portion shaped to receive and retain the buckle connector, a female connector portion connected to the second body portion, and a battery electrically coupled to the female connector portion and configured to provide energy to the transmitter when the male connector portion communicates with the female connector portion. The transmitter may generate a signal, indicating a presence of a child, when the transmitter receives energy from the battery.

A child safety seat checking system for a child safety seat of a vehicle, in particular a motor vehicle, is comprised of at least one child safety seat, a first checking device for checking whether a child is located in the child safety seat, and a second checking device for checking whether a person supervising the child is present, wherein the second checking device is designed to operate in an at least partly portable manner in an operating state of the child safety seat checking system and/or is designed to operate regardless of an on/off state of the vehicle.

The invention is an indicator means on a strap to provide a means of showing when slack in the strap is removed and/or tension is applied to the strap. The strap is secured with respect to an object at one end and to an anchor point at the other end and the indicator means shows visually that the strap has at least had all slack removed therefrom and where the indicator means is arranged to provide an indication from both sides of the strap to allow a visual indication of tension regardless of which direction the strap extends away from the object.

A child safety seat includes a first and a second restraining device, and an alert device and a first and a second switch serially connected in a series circuit. Each of the first and second restraining device is deployable to engage with a corresponding structure provided in a vehicle, each of the first and second restraining devices being operable independently and having an idle position and a deployed position. The first and second switches are respectively coupled operatively to the first and second restraining device, and are respectively closed when the first restraining device is in the deployed position and the second restraining device in the idle position. The alert device is thereby activable to emit an alert signal when the first restraining device is in the deployed position and the second restraining device in the idle position.

An assembly system warning device includes a first assembly member, a second assembly member, a main circuit, a power supply, an alarm device, a first circuit, a first switch, a second circuit and a second switch. When the first assembly member is located at an assembly position and the second assembly member is located at an idle position, the main circuit and the second circuit are connected in series to form a closed circuit. When the second assembly member is located at an assembly position and the first assembly member is located at an idle position, the main circuit and the first circuit are connected in series to form a closed circuit.

The present disclosure provides a new method and apparatus for a ratchet tensioning mechanism. The apparatus uses a spring release mechanism to limit the torque applied via the tensioning device to a predetermined level. In an alternative configuration the limit of the tension could be adjusted by the user.

A child car seat system includes a car seat having a strap with a restraining device to secure over a body of a child; a sensing system to be incorporated into the restraining device, the sensing system having a first sensor associated with a first half of the restraining device; a second sensor associated with a second half of the restraining device; a third sensor secured positioned within a body of the restraining device; a control system in electrical communication with the first, second, and third sensors; and an alarm in communication with the control system; the alarm is activated via the control system when the first sensor and the second sensor are separated from one another, such as when the restraining device is unsecure; and the third sensor is to alert the control system when the car seat is occupied.

Systems and methods define a stimulation pattern for a juvenile product utilizing a mobile device that executes a mobile application that is linked to the juvenile product. The method comprises the step of recognizing, by the mobile device when executing the mobile app, the user-defined stimulation pattern for the juvenile product. The stimulation pattern can be a vibration pattern or a motion pattern, and can be detected in a number of different ways by the mobile device. The method further comprises the step of determining control signals for the actuator(s) of the juvenile product based on the user-defined stimulation pattern that is recognized by the mobile device. The method further comprises the step of, in response to receiving a command to execute the user-defined stimulation pattern, controlling the actuator(s) of the juvenile product based on the stored control signals for the user-defined stimulation pattern.
