A child restraint includes a juvenile seat and a seat base. The juvenile seat is formed to include a child-receiving space configured to hold a child for transportation in a vehicle. The seat base configured to be secured to a vehicle seat to mount the juvenile seat to the vehicle seat during transportation in the vehicle. The juvenile seat is movable relative to the seat base.

Embodiments include a vehicle comprising a user interface, a first sensor coupled to a child seat for detecting a child seat belt status; a gear selector for selecting a vehicle gear, and a processor communicatively coupled to the first sensor and the gear selector, and configured to cause the user interface to present a first notification if a first alarm condition is detected based on the child seat belt status and a selected gear. Embodiments also include a method of providing child seat monitoring in a vehicle, the method comprising receiving a gear position from a vehicle gear selector, receiving a child seat belt status from a first sensor coupled to a vehicle child seat, and presenting a first notification using a vehicle user interface if the gear position is a non-park position and the child seat belt status is unbuckled.

Systems and methods of impact handling and ultrasound alerting are provided. Systems comprise an ultrasound transmitter is configured to transmit ultrasound signals at specified frequencies, a controller associated with a vehicle seat and configured to generate the ultrasound signals with respect to seat statuses and control the transmitter accordingly, and an application installable on a user's communication device to be associated with a device's audio receiver. The seat may comprise a dynamic part mounted on a static part and energy absorbing element(s) configured to restrain a movement of the dynamic part relative to the static part upon impact, via connection(s) between the static and dynamic parts that have static element(s) attached to the static part and dynamic element(s) attached to the dynamic part.

Embodiments include a vehicle comprising a user interface, a first sensor coupled to a child seat for detecting a child seat belt status; a gear selector for selecting a vehicle gear, and a processor communicatively coupled to the first sensor and the gear selector, and configured to cause the user interface to present a first notification if a first alarm condition is detected based on the child seat belt status and a selected gear. Embodiments also include a method of providing child seat monitoring in a vehicle, the method comprising receiving a gear position from a vehicle gear selector, receiving a child seat belt status from a first sensor coupled to a vehicle child seat, and presenting a first notification using a vehicle user interface if the gear position is a non-park position and the child seat belt status is unbuckled.

The present disclosure discloses a wireless sensing system of a seat position and a control method of the sensing system, the system including a slave control unit provided for each seat to detect a seat belt fastening status and a seat occupancy status by a passenger, and a master control unit provided in a vehicle to receive data based on a radio signal of the slave control unit through radio communication with each slave control unit, calculate a position of each slave control unit based on the data received through the radio communication, and discontinue a position checking of a slave control unit when it is determined that the position of the slave control unit calculated for each slave control unit is outside the vehicle.

A child restraint configured to be securable to and separable from a base installed in a vehicle, the child restraint comprising an illuminator positioned on an external portion of the child restraint, configured to operate in a first mode, illuminating a first region external to the child restraint wherein, in the event that the child restraint is not secured to the base, and the child restraint is moved, the illuminator will be activated in its first mode, illuminating the first region external to the child restraint for the purpose of aiding securement to the base, and wherein in the event that the child restraint is secured to the base, the first mode will be deactivated.

The present disclosure discloses a child safety seat, which is for being installed on a vehicle seat. The child safety seat includes a base having an anchor part connected to the vehicle seat; a seat coupled to the base; a top rod fixed to the rear of the base; a tether assembly including a top tether and a tether fixing portion that are connected with each other, the top tether being connected with the top rod and the tether fixing portion being connected with the vehicle seat; and an alarm device including a switch which can be triggered when the top tether is tightened. The present disclosure also discloses a tether assembly and a support structure. The child safety seat can conveniently prompt that it is not correctly fixed, and can be conveniently fixed and adjusted, thereby improving the safety and riding comfort of the child safety seat.

An occupant sensing method includes steps of: sensing installation of a child seat on a seat of a vehicle; storing a detection value of a load sensor which is provided to be attached to the seat and detects an input load as a first load value, when the installation of the child seat is sensed; storing a detection value of the load sensor as a second load value when a predetermined time period has elapsed from a time point at which the installation of the child seat is sensed; and estimating a load change amount at the time of getting on/off which is a change amount of a load that is generated as the occupant gets on/off the child seat, based on a difference value between the first load value and the second load value.

A system and application to alert parents or guardians to the solitary status of a dependent accidentally left within the confines of a vehicle is described. The system alerts individuals in the event that a dependent such as a child is left behind via the use of sensors configured to detect the presence of the dependent, and determine if he or she is alone. Upon recognizing that the dependent has been left alone, an alert is sent to the parent or guardian's wirelessly connected key fob and/or mobile device via a proprietary mobile application. Simultaneously, the system employs an active display sticker, configured to calm or entertain the dependent left within the vehicle until the alerted parent or guardian returns.

Methods and systems for detection of removable vehicle seats may be used to indicate presence or absence of a child in the vehicle. In some examples, an alarm system includes a radio frequency (RF) transceiver and a removable seat magnetic coupling. Various actions are triggered when the parent (e.g., guardian) goes beyond a predefined range while the removable seat is within the vehicle, such as sounding an alarm on a mobile electronic device.
