A sensor system for determining extension or tension in a seat belt of a seat-belt system in which the belt extends from and can be wound up on a retractor. The system has an electrical conductor extending longitudinally along the belt, a retractor for paying out and winding up the belt and the conductor thereon, and n electrode juxtaposed with the retractor. A controller connected to the conductor applies an electrical voltage to the conductor and is also connected to the electrode for detecting the voltage in the conductor.

A variable force limiter control system for a vehicle includes a variable force limiter mechanism, a relative speed sensor, an acceleration sensor and an electronic control unit. The variable force limiter mechanism is configured to change a force limiter load. The relative speed sensor is configured to detect a relative speed of the vehicle with respect to a collision object before a collision. The acceleration sensor is configured to detect an acceleration of the vehicle. The electronic control unit is configured to predict a severity of a collision on the basis of at least the relative speed. The electronic control unit is configured to control the force limiter load on the basis of both the predicted severity and the acceleration in an initial stage of the collision of the vehicle.

The present invention is comprised of a color changing device in the form of film or fabric that can be either integrated with a vehicle seatbelt or an add-on device that can be easily attached to the seatbelt. The color changing device will change its color when experiencing external stress. Different colors will indicate different external load applied to the seatbelt, which is used to determine if the seatbelt is properly tightened to secure a CRS. The invention can also be integrated into cargo mounting webbing to indicate webbing tightness used for securing and transporting cargo on trucks or other vehicles.

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.

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.

A tilt-lock adjuster system includes a tilt-lock adjuster that is used to tighten and loosen webbing. The tilt-lock adjuster includes an indicator configured to indicate when proper tension is applied to the webbing. The tilt-lock adjuster has a frame to which the indicator is slidably coupled and a web bar slidably coupled to the frame. The web bar is asymmetric for one way assembly with the frame. The web bar has a web engagement notch that is concave for enhancing locking of the webbing to the frame. The web bar has a frame guide slidably engaged to the frame. The frame defines a web opening in which the frame engagement ledge extends. The frame guide of the web bar includes a key guide foot. The frame has an orientation notch configured to receive the key guide foot of the web bar.

An apparatus for proper application of a seat belt in a vehicle. The apparatus includes the seat belt and a seat belt buckle which is assigned to it and which is provided with a measuring device, arranged for measuring a tensile force exerted on the seat belt buckle. The apparatus further relates to an evaluation device for evaluating the measured tensile force. At the same time, it is provided that the apparatus is also equipped with a tightening device for applying a tightening force to the seat belt, as well as with a detection device for detecting the applied tightening force. The evaluation device compares the tensile force to the tightening force and determines based on a corresponding comparison result whether the seat belt has been properly placed and secured in the seat belt buckle.

The invention relates to a safety belt, which is in particular intended to be installed in an aircraft seat, comprising: a closing loop comprising a male element and a female element, a first strap which is connected to the male element and a second strap which is connected to the female element, the first strap and the second strap being capable of being attached together by means of the closing loop, which can change from an open state to a closed state through cooperation between the male element and the female element, the safety belt further comprising: a system for detecting that the safety belt is in the closed stated, the system being capable of generating an information item relating to a closed state of the safety belt, and a system for detecting that the safety belt is in a mechanically tensioned state, said system being capable of generating an information item relating to a mechanically tensioned state of at least one strap of the safety belt.

There is provided a vehicle seat belt system including: webbing that has one end anchored to one seat width direction side surface of a vehicle seat or to a vehicle body, and that restrains an occupant seated in the vehicle seat; a retractor to which another end of the webbing is engaged and that is configured to take up the webbing, the retractor being provided with a pretensioner which, when activated, pulls in the webbing; a buckle, with which a tongue plate attached to the webbing can be engaged; a force limiter that allows the buckle to move to thereby reduce a tensile load acting on the webbing due to activation of the pretensioner; and a warning section that is configured to utilize movement of the buckle resulting from the force limiter to notify the occupant of an abnormality that the force limiter has been activated.
