An occupant crash protection includes: a seatbelt that restrains a front-seat occupant sitting in a front seat; a retractor that is installed inside a seatback of the front seat and reels in one end side of the seatbelt, inserted inside the seatback, so as to allow the seatbelt to be pulled out; and a rear-seat airbag module that is installed inside the seatback, on a seat rear side relative to the seatbelt, and inflates and deploys an airbag toward the seat rear side of the seatback while inflating a part of the airbag toward a seat front side so as to press the seatbelt toward the seat front side.

A method for determining the severity of a possible collision between a motor vehicle and another vehicle is disclosed. Sensor data which describes the other vehicle is received from at least one sensor of the motor vehicle by means of a control apparatus, a change in velocity which describes a difference between a velocity (V1) of the motor vehicle before the collision and a collision velocity (Vc) of the motor vehicle (1) after the collision is determined on the basis of the sensor data, and the severity of the possible collision is determined on the basis of the determined change in velocity, wherein a mass (m2) of the other vehicle is estimated by means of the control apparatus on the basis of the sensor data, and the severity of the possible collision is additionally determined on the basis of the estimated mass (m2).

A vehicle includes an inertial sensor configured to measure a speed, a steering angle, and a yaw rate, a camera configured to acquire image data, a radar configured to acquire a radar data, and a safety device including an air bag and a seat belt pretensioner. A controller is configured to predict a collision with a first object located at the outside of the vehicle based on the image data or the radar data, predict a collision with a second object that is likely to occur after the collision with the first object based on an angle of reflection predicted at a time of the collision with the first object, and lower a deployment threshold that is compared with a collision severity such that the safety device is deployed before the collision with the second object.

A method and system for determining whether a seatbelt of a vehicle is fastened is provided. The system may be configured to detect markers on a seatbelt, engage seatbelt tensioners, and determine whether the markers have moved. The system may then be configured to determine whether the seatbelt is fastened based on movement of the markers.

A vehicle seatbelt device of an embodiment includes a recognizer that recognizes circumstances around a vehicle, a steering operator that is able to adjust steering of the vehicle, a vibrator that causes a portion of the steering operator to vibrate, a seatbelt that restrains a portion of the body of an occupant of the vehicle, a tension adjustment mechanism that is able to adjust the tension of the seatbelt, and a controller that controls the vibrator and the tension adjustment mechanism on the basis of the circumstances recognized by the recognizer.

A wheelchair occupant restraint device includes: a wheelchair retractor which is disposed in a vehicle cabin, and around which one end portion of a wheelchair belt member is wound; a wheelchair buckle which is disposed on the opposite side of a securing space for a wheelchair from the wheelchair retractor, and on which a wheelchair tongue plate attached to the other end portion of the wheelchair belt member is able to be mounted; an occupant retractor which is disposed on the opposite side of the securing space from the wheelchair retractor, and around which one end portion of an occupant belt member is wound; and an occupant buckle which is disposed on the opposite side of the securing space from the occupant retractor, and on which an occupant tongue plate attached to the other end portion of the occupant belt member is able to be mounted.

Embodiments described herein generally relate to a system for preventing the automatic retraction of a seatbelt. The system generally includes one or more processors, one or more host vehicle status sensors, one or more seatbelt braking mechanisms, and one or more memory modules. The one or more host vehicle status sensors output a status signal that a host vehicle is stopped an off-road driving condition. The one or more memory modules store logic that causes the one or more processors to determine that the host vehicle is in the off-road driving condition based on the status signal output by the one or more host vehicle status sensors and activate the one or more seatbelt braking mechanisms in response to detecting the host vehicle is in the off-road driving condition to prevent automatic retraction of the seatbelt.

An anchor pretensioner module for a seat belt includes: an anchor which is disposed at a side of a seat cushion, and to which a tongue of the seat belt is fastened, a base which is provided at a lower side of the anchor, the base having a first operating part, which generates an explosive pressure, provided at a rear of the base, and a second operating part, which generates the explosive pressure, provided at a front of the base, a first wire which is connected to the base and the anchor, and allows the anchor to be moved downward when the first operating part is operated, and a second wire which is provided on the base, and moves the first wire while being inserted into the base when the second operating part is operated to allow the anchor to be moved forward while moving downward, so that a relative location of the anchor is moved when a collision occurs to restrain a passenger's body.

A vehicle includes a safety device, a camera sensor configured to detect an obstacle around the vehicle, a radar sensor configured to detect the obstacle around the vehicle, and a controller configured to predict a collision state and a collision position of the vehicle through the camera sensor and the radar sensor, determine whether to control the safety device based on at least one of a vehicle type, a collision speed, a seat position of an occupant, whether the occupant wears a seat belt, a gender of the occupant, whether the occupant is an infant, or a size of the occupant, in response to a prediction result, and control the safety device depending on device determination result.

A seatbelt system includes a take-up device configured to take up a seatbelt, and an electronic control unit configured to, when any one of first and second conditions is satisfied, cause a motor to take up the seatbelt. In the first condition, after occurrence of a collision whose physical quantity detected by a detector configured to detect the physical quantity associated with a magnitude of the collision is less than or equal to a first threshold, the physical quantity decreases to less than or equal to a second threshold. In the second condition, after occurrence of a collision whose physical quantity is less than or equal to the first threshold, a first predetermined time elapses, which is estimated to be equivalent to a decrease in the physical quantity to less than or equal to the second threshold.
