A method for recognizing a seat occupancy of seats in a motor vehicle including a) preparing a checking sequence of the seats at least using a probability of occupancy of the seats, and b) sequentially checking the occupancy of the seats using the checking sequence prepared in step a).

A seat belt take-up control system includes: a first belt-take-up unit mounted at a child seat, the first belt-take-up unit taking up a seat belt of a vehicle seat and applying a predetermined tension at a time of fastening the seat belt; a belt lock unit that prevents pulling out of the seat belt in a state which the seat belt has been taken up by the first belt-take-up unit; and an second belt-take-up unit that, in a state in which pulling out of the seat belt has been locked by the belt lock unit, takes up the seat belt and applies a predetermined tension after the seat belt is fastened in at least one of a case in which pulling out of the seat belt is detected or a case in which a predetermined period of time has elapsed.

A method for providing an activation signal activating a vehicle occupant protection device includes reading in passenger compartment data from a passenger compartment detection unit and seat belt data from a seat belt sensor. The passenger compartment data represent a passenger compartment of the vehicle. The seat belt data represent a seat belt fastening angle of a seat belt of the vehicle at a belt reversing point relative to a reference axis of the vehicle. The method also includes determining, based on the passenger compartment data, a piece of seat position information representing an occupancy state of a vehicle seat by an occupant and a relative position of the seat relative to the vehicle; ascertaining an occupant class, representing a physical characteristic of the occupant, using the seat position information seat belt data; and generating the activation signal using the seat position information and the occupant class.

A seat belt for an occupant sitting on a seat in a vehicle includes a tongue part provided at a first side portion of the seat and a buckle part provided at a second side portion of the seat. The tongue part includes at least one first guide part that is operable between extended and contracted configurations, and at least one first webbing with a tongue wound therein. In addition, the tongue of the first webbing is connected with an end portion of the first guide part. The buckle part includes a second guide part that is operable between extended and contracted configurations, and the second webbing with a buckle wound therein. In addition, the buckle of the second webbing is connected with an end portion of the second guide part. The tongue of the tongue part is fastened to the buckle of the buckle part.

A vehicle safety system includes a vehicle that has a plurality of seats, a plurality of seat belts, an electrical system and an ignition. Each of the seat belts includes a buckle and a clasp. A plurality of buckle sensors is provided and each of the buckle sensors is coupled to the buckle on an associated one of the seat belts. Each of the buckle sensors senses when the clasp of the associated seat belt is engaged to the buckle of the associated seat belt. A plurality of weight sensors is provided and each of the weight sensors is coupled to an associated one of the seats to sense weight of an occupant in the associated seat. A shut down unit is coupled to the vehicle. The shut down unit is in electrical communication with each of the seat belt sensors, each of the weight sensors and the ignition. The shut down unit turns the ignition off when any of the weight sensors senses an occupant in an associated of the seats and the buckle sensor corresponding to the associated seat does not sense the seat belt of the associated seat is fastened.

A computer that may be programmed to: in response to receiving an indication that a vehicle is approaching a geofence boundary, retract slack in a webbing associated with a seat in the vehicle by actuating a seatbelt retractor; then receive measurement data from one or more sensors associated with the seat; using the data, determine whether an occupant occupies the seat; and when no occupant occupies the seat, then transmit an instruction to stop the vehicle.

A vehicle warning device includes a housing disposed at a front of a roof in a vehicle compartment, a plurality of light emitting units provided in the housing to emit warning light having directionality, a seating sensor that detects a seated state of an occupant on each of back seats in the vehicle compartment, a wearing sensor that detects a wearing state of a seat belt of each of the back seats, and an ECU that controls turning on of each of the light emitting units based on the seated state and the wearing state, and each of the light emitting units corresponds to the occupant on each of the back seats, and has an optical axis disposed with respect to the housing toward an eye point region ER including an eye point of the occupant on the back seat.

A seat belt wearing encouragement apparatus includes a wearing state detecting unit to detect a wearing state of a seat belt; a wearing determination unit to determine whether the seat belt is worn, based on the wearing state; a vehicle speed detecting unit to detect a vehicle speed of the vehicle; a warning unit to warn the passenger; a warning command unit to issue a command to the warning unit to execute warning if the vehicle speed detecting unit has detected the vehicle speed exceeding a setting speed, and the wearing determination unit has determined that the seat belt is not being worn properly; and a vehicle speed limiting unit to limit the vehicle speed in a case where even after a predetermined time has elapsed since the warning was executed, the wearing determination unit still determines that the seat belt is not being worn properly.

A child seat misuse warning system for a vehicle, comprising a child seat having one or more misuse sensors embedded in the child seat, the one or more misuse sensors being configured to obtain data regarding a state of installation of the child seat; and transmission means configured to transmit data obtained by the misuse sensors to a vehicle; a terminal configured to be embedded in a vehicle and to receive data transmitted by the transmission means, the terminal comprising display means configured to display signals to a user; the child seat being communicatively connected to the terminal; wherein the child seat warning system is configured to, on the basis of the data obtained by the misuse sensors and received by the terminal, display a signal with the display means indicating whether the installation of the child seat is in a misuse state.

Methods, systems and apparatuses may provide for technology that conducts an automated vision analysis of image data associated with an interior of a vehicle cabin, determines a state of a child restraint system (CRS) based on the automated vision analysis, and generates an alert if the state of the CRS does not satisfy one or more safety constraints. In one example, the technology identifies the safety constraint(s) based on a geographic location of the vehicle cabin.
