A buckle switch-and a microcontroller are provided. A power supply is connected to the buckle switch, which switches the connection with the power supply between a connected state and a disconnected state. The microcontroller is connected with the buckle switch and includes a removal switch input port and a removal control port. The removal switch input port detects the state of the buckle switch. The removal control port is connected to the buckle switch-via a pull-down resistance and controls whether the pull-down resistance operates. The microcontroller controls the removal control port such that the pull-down resistance does not operate when the buckle switch is in the connected state and such that the pull-down resistance does operate when the buckle switch is in the disconnected state.

There are provided a buckle switch that detects an insertion of a tongue into a buckle of a seatbelt and an ejection of the tongue from the buckle, a signal transmitting section that wirelessly transmits a signal showing a state of the buckle switch, and an attaching detection control unit that controls the signal transmitting section such that the signal transmitting section transmits different signals that correspond to a first time lasting from the insertion of the tongue into the buckle until the ejection of the tongue from the buckle or a second time lasting from the ejection of the tongue from the buckle until the insertion of the tongue into the buckle.

A safety on-board vehicle multi-force restraint self-controlling system improves the security of the air bags for children and light women passengers according requirements of the final rule of Section §571.208 Standard No. 208; “Occupant crash protection” by employing the accurate weight occupant KEF technology. The system also provides, in case of an accident, different forces applied to the occupant bodies of different weight categories by employing an original occupant's weight, measured at the beginning of a trip by innovative weighing KEF technology, which is eventually modified during the trip according to the current values of the morphological and driving factors. The system provides secure personalization of the occupants' weight by a finger print sensor. From beginning and during the trip, an extracting unit continuously monitors the needed combination of openings that gives an access for the extra gas to move from inflator to the atmosphere by a signal from the crash sensor, and the combination satisfies the code of the accurate original weight of the occupant, modified according to the current morphological and the car trip situation parameters: car crash severity, position of the occupant, seat belt state, and other possible parameters of the current trip situation. The multi-force restraint system provides a self-control and prevents the inflator from rupturing when an excessive internal pressure is produced.

A system and method for determining when a child safety system is present in a passenger seat in a vehicle and restrained, including at least one of: a) two lower anchors each including a lower anchor sensor, or b) an upper anchor including an upper anchor sensor; an occupancy sensor; a seatbelt buckle sensor; a microprocessor control system in communication with at least one of the sensors. The microprocessor control system includes executable code to: provisionally determine whether the child safety system is detected in the passenger seat; determine whether at least one of: a) a strap is connected to each lower anchor and b) a tether is connected to the upper anchor; determine whether the seatbelt is buckled; and verify the presence of a child safety system in the passenger seat. Executable code can also be included to detect strap and tether tension.

A system and method for a vehicle includes detecting within a first predetermined time period of a vehicle ignition transitioning to from an OFF status to an ON status: (a) a rear door OPEN status; and (b) at least one of: (i) a stored record of rear seat occupancy; and (ii) a rear seat belt BUCKLED status; and outputting a rear seat occupancy indicator within the vehicle upon detecting the vehicle ignition transitioning from the ON status to the OFF status.

A seat belt device includes a webbing and a tongue. The webbing includes a lap belt and a shoulder belt. At least a portion of the lap belt is configured to be disposed to extend in a vehicle-width direction along a front of an abdomen of an occupant. At least a portion of the shoulder belt is configured to be disposed obliquely along a front of a chest of the occupant. The tongue is provided between the lap belt and the shoulder belt of the webbing and is configured to be coupled to a vehicle body when the tongue is to be mounted. The tongue rotates in accordance with a collision or a warning of the collision of a vehicle in a direction in which the shoulder belt is twisted with respect to the vehicle body.

A vehicle airbag control system includes an airbag module, a temperature detector and an electronic controller. The airbag module is for a vehicle. The airbag module has an airbag with a vent. The temperature detector configured to detect an ambient temperature of the vehicle. The electronic controller is programmed to control the airbag module between an active venting condition and a non-venting condition based on a detected result detected by the temperature detector. The vent is in an open state in the active venting condition. The vent is in a closed state in the non-venting condition.

A system includes a seat belt routing module and a user interface device (UID) control module. The seat belt routing module is configured to: determine a routing of a seat belt relative to an occupant in a vehicle seat based on input from a webbing payout sensor; and determine the seat belt routing based on an input from an in-cabin sensor. The in-cabin sensor includes at least one of a camera, an infrared sensor, an ultrasonic sensor, a radar sensor, and a lidar sensor. The UID control module is configured to control a user interface device to indicate that the seat belt is being worn improperly when: the seat belt routing determined using at least one of the webbing payout sensor and the in-cabin sensor is improper; and the seat belt routing determined using the webbing payout sensor corresponds to the seat belt routing determined using the in-cabin sensor.

An electronic module assembly (EMA) for use in controlling one or more personal restraint systems. A programmed processor within the EMA is configured to determine when a personal restraint system associated with each seat in a vehicle should be deployed. In addition, the programmed processor is configured to perform a diagnostic self-test to determine if the EMA and the personal restraint systems are operational. In one embodiment, results of the diagnostic self-test routine are displayed on a display included on the electronic module assembly. In an alternative embodiment, the results of the diagnostic self-test routine are transmitted via a wireless transceiver to a remote device. The remote device can include a wireless interrogator or can be a remote computer system such as a cabin management computer system.

A vehicle airbag control system includes an airbag module, a temperature detector and an electronic controller. The airbag module is for a vehicle. The airbag module has an airbag with a vent. The temperature detector configured to detect an ambient temperature of the vehicle. The electronic controller is programmed to control the airbag module between an active venting condition and a non-venting condition based on a detected result detected by the temperature detector. The vent is in an open state in the active venting condition. The vent is in a closed state in the non-venting condition.
