Method for adjusting a position of a vehicle seat
10974627 · 2021-04-13 · ·

A method for adjusting a position of a vehicle seat from a reclined position to a pre-determinable safety position. The method includes detecting an imminent or ongoing frontal or semi-frontal collision, pretensioning a seat belt associated with the vehicle seat, the seat belt being directly or indirectly attached to a backrest of the vehicle seat, and adjusting the position of the vehicle seat from the reclined position to the pre-determinable safety position by means of a seat adjustment means associated with the vehicle seat, the seat adjustment means being actuated by a collision force generated by the imminent or ongoing frontal or semi-frontal collision and applied via a seat occupant and/or the seat belt to the vehicle seat. The present invention also relates to an occupant safety arrangement for a vehicle seat.

Seatbelt control device

A seatbelt retractor device includes a pre-tensioner section, and a force limiter section that can change a magnitude of a load at which to start reducing tension of the retracted seatbelt. A seatbelt control ECU activates the pre-tensioner section when a deceleration G detected by a floor sensor exceeds a first threshold, and acquires a collision velocity from a radar device and sets a second threshold value to a lower value the greater the collision velocity. The seatbelt control ECU controls the starting load for tension reduction by the force limiter section to be a high load when the deceleration G has exceeded the second threshold within a determination time period after activation of the pre-tensioner section, and controls the starting load for tension reduction to be a low load when which the deceleration G has not exceeded the second threshold within the determination time period.

REAR OCCUPANT PROTECTION APPARATUS AND METHOD OF CONTROLLING THE SAME
20210129791 · 2021-05-06 ·

Disclosed are a rear occupant protection apparatus and a control method thereof for controlling a seat belt, or an airbag, based on the state of a rear occupant and a vehicle driving environment to safely protect the rear occupant. The rear occupant protection apparatus includes a first monitoring unit configured to monitor a state of a rear occupant, a second monitoring unit configured to monitor a surrounding situation of a subject vehicle, and a controller configured to control the first and second monitoring units, wherein the controller controls the first and second monitors units to monitor the state of the rear occupant and the surrounding situation of the subject vehicle when the rear occupant wears a seat belt, and controls the seat belt seat belt worn by the rear occupant based on at least one of the state of the rear occupant or the surrounding situation of the subject vehicle.

VEHICLE OCCUPANT RESTRAINT SYSTEM
20210107429 · 2021-04-15 · ·

A CPU of an ECU is configured to compute an estimated acceleration that is estimated to be applied to a vehicle and a remaining time that is taken from present time to acceleration occurrence time at which the estimated acceleration occurs from a road surface condition detected by a road surface condition detection unit and a vehicle status detected by a vehicle speed determination unit and a steering angle velocity determination unit. The CPU is configured to, when the remaining time becomes shorter than or equal to a predetermined value, drive a retractor motor. The webbing is retracted before an occupant moves with an acceleration that is applied to the vehicle, so the occupant is held in a normal seated position. The retractor motor is driven when the time that is taken from present time to acceleration occurrence time becomes shorter than or equal to the predetermined value.

ELECTRICAL ASSEMBLY
20210107419 · 2021-04-15 ·

An electrical assembly includes a first controller, a track assembly, and/or a support assembly configured for selective connection with the track assembly. The support assembly may include a second controller, a sensor, and/or a plurality of safety devices. The first controller may be configured to provide crash information to the second controller. The second controller may be configured control the plurality of safety devices according to the crash information and information from the sensor. The first controller may be connected to the second controller via at least two wireless connections. The at least two wireless connections may include at least one of induction coupling, magnetic field generation and detection, and light transmission. The first controller may be configured to provide the crash information to the second controller only via one or more wireless connections.

Method for Dynamically Restraining an Occupant Fastened into a Vehicle Seat with a Seatbelt
20230406248 · 2023-12-21 ·

A method for dynamically restraining an occupant fastened into a vehicle seat with a seatbelt in a vehicle, where a transverse acceleration of the vehicle and a course of a road ahead of the vehicle are determined and the seatbelt is tightened with a predefined belt force a predefined length of time before the vehicle enters a bend that has a predefined curvature. The method includes assigning a respective comfort speed to different turning angles of turnoffs and turnings at which it is possible to comfortably drive into the turnoffs or around the turnings. When the vehicle nears a turnoff or a turning at a current driving speed that exceeds the comfort speed assigned to the turning angle by a predefined value, the seatbelt is tightened with a predefined belt force before the turnoff or the turning is reached.

METHOD FOR OPERATING AN OCCUPANT PROTECTION DEVICE
20210086714 · 2021-03-25 ·

A method for operating an occupant protection device of a vehicle involves triggering an occupant protection mechanism, in the event of an imminent detected collision for the vehicle or of a detected collision of the vehicle. The triggering also depends upon detected image data of at least one interior camera of the vehicle and the triggering can be supressed based on the detected image data of the interior camera.

Occupant protection device

An occupant protection device including a seat belt that includes a shoulder belt and a lap belt, a locking tongue that is capable of switching between an unlock state and a lock state, a shoulder-belt puller that is capable of pulling the shoulder belt, a lap-belt puller that is capable of pulling the lap belt, a side-collision detector that detects a side collision or a precursor thereof, and a control unit that changes a state of the locking tongue into the lock state and a state of the lap-belt puller into a first pulling state in which the lap-belt puller pulls the lap belt and that subsequently changes a state of the shoulder-belt puller into a second pulling state in which the shoulder-belt puller pulls the shoulder belt when the side-collision detector detects the side collision that occurs opposite an occupant or the precursor thereof.

Seatbelt detection using computer vision

An apparatus includes a capture device and a processor. The capture device may be configured to generate a plurality of video frames corresponding to an interior view of a vehicle. The processor may be configured to perform operations to detect objects in the video frames, detect (a) occupants of the vehicle and (b) seats of the vehicle based on the objects detected in the video frames, determine a status of a seatbelt for each of the occupants and select a reaction based on (a) a state of the seatbelt and (b) characteristics of the occupants. The reaction may be selected to encourage proper usage of the seatbelt based on the characteristics of the occupants. The characteristics may be determined by performing the operations on each of the occupants.
