A driver assistance system for a vehicle may comprise a control unit that is configured to determine a state of a vehicle occupant via a neural network. The control unit may also activate a safety belt system for positioning and securing the vehicle occupant based on the identified state of the vehicle occupant.

An occupancy sensor is provided for detecting the occupancy status of a wheeled mobility device securement system. The occupancy sensor may additionally confirm adequate tightness of the wheeled mobility device securement system and/or provide an indication of the magnitude of tightness. In one embodiment, the occupancy sensor comprises a spring-loaded follower that breaks the straight-line path of a wheeled mobility device tie down as it travels between two touch points. The follower is displaceable from an extended position to a compressed position in response to the magnitude of tension applied to the tie down. Proximity sensors are used to detect the displacement distance of the follower, thereby providing an indication of occupancy, adequate securement, and/or the magnitude of tension.

An occupant protection device for a vehicle includes: a three-point seatbelt device having a seatbelt extendable across a front of an upper body of an occupant sitting on a seat; and a belt airbag device including a belt airbag that is provided at a shoulder belt section, which is extendable from a shoulder to a waist of the occupant, of the seatbelt the belt airbag being configured to be deployed when a collision occurs. The belt airbag includes a belt-direction deployment section extendable and deployable along the shoulder belt section, and an intersecting-direction deployment section extendable and deployable in a direction intersecting the shoulder belt section. The belt-direction deployment section and the intersecting-direction deployment section are configured to form a single bag by being coupled to each other below a head of the occupant sitting on the seat.

A vehicle occupant protection apparatus has a strap configured to extend across the front of a body of an occupant sitting on a seat of a vehicle, a pre-tensioner configured to retract the strap, a vehicle orientation sensor configured to detect either one of a change in the orientation of the vehicle and an operation for changing the orientation, and a controller configured to cause the pre-tensioner to start retracting the strap prior to a collision or when a collision occurs. After the retracting of the strap starts, the controller temporarily stops or eases the retracting of the strap in accordance with the change in the orientation of the vehicle.

A seatbelt system may include a seatbelt configured to constrain a waist and a torso of an occupant. The seatbelt may also include a coupling configured to selectively couple a portion of a vehicle and the seatbelt to one another. The system may also include a reel configured to receive at least a portion of the seatbelt, and a tension sensor associated with the coupling and/or the seatbelt and configured to generate a signal indicative of tension in the seatbelt. The system may also include a deployment sensor associated with the seatbelt and configured to generate a signal indicative of a length of the seatbelt deployed from the reel. The system may also include an occupant detector configured to determine, based at least in part on the signals indicative of tension and the length, whether an occupant is properly wearing the seatbelt, such that the seatbelt constrains the occupant.

An airbag safety system is provided with two or more safety airbags which can be adjoined to protect the rider when a crash occurs. A stabilizing mechanism is used to cause the inflated airbags to adjoin each other so as to form a stable protection space between the vehicle and the adjoined airbags. The adjoined airbags are shaped to meet a rider's ergonomics, making sure the rider can be caped for head protection and can be protected within the space surrounded by the airbags from being thrown away off the vehicle and subject to serious injuries.

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 seatbelt system may include a seatbelt configured to constrain a waist and a torso of an occupant. The seatbelt may also include a coupling configured to selectively couple a portion of a vehicle and the seatbelt to one another. The system may also include a reel configured to receive at least a portion of the seatbelt, and a tension sensor associated with the coupling and/or the seatbelt and configured to generate a signal indicative of tension in the seatbelt. The system may also include a deployment sensor associated with the seatbelt and configured to generate a signal indicative of a length of the seatbelt deployed from the reel. The system may also include an occupant detector configured to determine, based at least in part on the signals indicative of tension and the length, whether an occupant is properly wearing the seatbelt, such that the seatbelt constrains the occupant.

Vehicle passenger space contact mitigation (e.g., using a computerized tool) is enabled. For example, a system can comprise a memory that stores computer executable components, and a processor that executes the computer executable components stored in the memory, wherein the computer executable components comprise: a calculation component that determines a distance between an occupant of a vehicle and an object of the vehicle, and an impact mitigation component that, based on the distance, facilitates an action determined to mitigate an impact between the occupant and the object.

A computer-implemented method for automated evaluation of crash test data includes reading a data set with crash test data from a plurality of available data sets. The method proceeds by extracting from the data set time-dependent force signals that are attributable to a seatbelt tensioner of a passenger restraint system of a vehicle and calculating changes in force F.sub.i from the force signals at fixed or determinable time intervals between 0.05 ms and 0.15 ms, up to a fixed or determinable time threshold between 20 ms and 30 ms, starting from the time of vehicle impact on the barrier. The method then includes checking whether the force change F.sub.i reaches or exceeds a fixed or determinable threshold value within the time threshold in at least one of the time intervals.
