The present invention provides a child safety seat. The pitching angle adjustment of the child safety seat is achieved through the angle adjustment mechanism. The connecting rod is connected to the driving mechanism, and the shaft sleeve sleeving the connecting rod is driven by the motor. The gears are mounted at the two ends of the shaft sleeve, and the gears are driven by the shaft sleeve to move on the rack. The rack is mounted on the base plate, so that the seat body can adjust the angle on the base plate. The connecting rod and the seat frame form the fixed supporting structure, so that the stability of angle adjustment is better. By the arrangement of the protective device on the seat portion, the probability of accidentally injuring a child during the turning of the seat body is reduced, and the safety of use is improved.

Arrangement for controlling a component having multiple states includes a device that generates a signal at a frequency that enables it to be conducted through a human body, and a conductive surface coupled to the device, situated in a position accessible by a part of the human, and which enables proximity or contact of the part of the human to the conductive surface to develop a reactive coupling between the human and the conductive surface. The component has multiple, different states and is controlled by the human to change from a first state to a second state upon completion of an electrical circuit including the component, the conductive surface and the device upon developing reactive coupling between the human and the conductive surface when the device is generating the signal conducted through the human. The component may be a vehicular component such as a door or window.

Systems and methods including at least one internal sensor attached internally to a vehicle, at least one external sensor mounted externally to the vehicle, wherein the external sensor detects at least one of a distance of other vehicles, a speed of other vehicles, driving patterns of other vehicles, and weather conditions; and at least one display configured to receive input from the internal sensor and the at least one external sensor, wherein the at least one display notifies a driver of an adjacent vehicle and/or a system controlling an adjacent manually-driven, semi-autonomous, or self-driving car of at least one of the occupation status of the vehicle, operational status of the vehicle, weather conditions, changing driving behaviors, when the adjacent vehicle exceeds a speed threshold, and/or when the distance between the vehicle and the adjacent vehicle falls below a minimum separation distance.

A seat for a vehicle includes a passenger seat, an independent seat positioned behind the passenger seat and operated independently from rear seats, and a sliding rail disposed on a vehicle floor in a longitudinal direction of the vehicle, in which each of the passenger seat and the independent seat is coupled to the sliding rail, so as to independently slide on the sliding rail.

A seat occupancy determination apparatus includes a seat belt attachment detection portion, a first and a second load detection sensors, a front-rear load sum computing portion, a front-rear load difference computing portion, a memory portion, an adult possibility determination portion, and a child safety seat determination portion determining a vehicle seat determined as possibly occupied by an adult is occupied by a child safety seat in a case where a first predetermined amount increase condition satisfies by a front-rear load difference value within a time range between a time of engagement and a first time point increases by a first predetermined amount or more from the value at the first time point or earlier and a second predetermined amount decrease condition satisfies by the front-rear load difference value decreases by a second predetermined amount or more within a time range between the time of engagement and a second time point.

A programmable proximity alert system for providing a sensory reminder to a parent when the exit the vicinity of a vehicle possibly containing their child. The programmable proximity alert system comprises a remote receiver adapted to sense the presence of a seat transmitter that it has been paired with and provide plural sensor alerts upon exiting from within a predetermined proximity of the seat transmitter, as well as a coding remote for initiating a bonding request that pairs a remote receiver and a seat transmitter.

A system for guiding installation of car seat base and a corresponding car seat includes sensors mounted on the car seat base for detecting a progress in a plurality of sequential installation steps. The installation steps are required for installing the car seat base and the corresponding car seat on a vehicle seat. The car seat base further includes light emitting elements arranged at various locations on the car seat base, each location corresponding to one of the installation steps. A processor is adapted to execute code instructions for, in response to outputs of the sensors, identifying completion of a current installation step. The processor is further adapted to instruct a suitable light emitting element to indicate a location corresponding to an installation step following the current installation step. An anti-rebound device includes a spring or piston that adaptively adjusts in response to an impact and a locking mechanism.

A method for occupancy detection for at least one vehicle seat, using at least one transmit antenna and a plurality of receive antennas, includes: emitting a detection signal with each transmit antenna onto at least one vehicle seat, which detection signal is a frequency-modulated continuous-wave radar signal, and receiving with each receive antenna a reflected signal; recording sample data representing the reflected signal, the sample data having M channels, with M=N1.Math.N2, where N1 is the number of transmit antennas and N2 is the number of receive antennas; for each channel, removing a component from the sample data that corresponds to a reflection from a static object; and applying a frequency estimation method to the sample data to at least implicitly determine at least one angle of arrival .sub.i corresponding to a position of an occupant on a vehicle seat.

Systems and methods for automatically evaluating a vehicle seat replacement after a vehicle collision. Upon detecting a vehicle collision is detected, obtaining vehicle seat condition data from vehicle seat sensors and vehicle condition data from vehicle sensors. Analyzing the vehicle seat condition data and/or the vehicle condition data to detect one or more collision conditions indicating (i) the vehicle is not drivable, (ii) a vehicle door proximate the vehicle seat is damaged, (iii) an airbag of the vehicle is deployed, and/or (iv) the vehicle seat is visibly damaged. In response to detecting the one or more collision conditions, generating a recommendation to replace the vehicle seat and providing the recommendation to a user device.
