A vehicle safety system for helping to protect an occupant of a vehicle seat includes a seatbelt extensible around the occupant to help restrain the occupant in the vehicle seat. The seatbelt includes a lap belt configured to extend across the occupant at the hips. An airbag is secured to the lap belt and configured to inflate and deploy upward from the lap belt to a deployed position in front of the occupant. The system is configured to adjust the deployed position of the airbag in response to the position of the occupant.

A seatbelt height adjuster includes a track elongated along an axis and including a plurality of holes spaced from each other along the axis, a slider slideably coupled to the track, a D-ring supported by the slider, a pin supported by the slider and releasably engageable with one respective hole, and a pyrotechnic actuator supported by the slider and engaged with the pin.

A method for a seat belt system (10) in a vehicle (14), the seat belt system (10) comprising a control unit (36) and at least one seat belt (18) with an extendable webbing (20) and a webbing extension measuring device (30), includes the steps of: a) determining whether a vehicle seat (16) is occupied, b) determining whether the webbing (20) is in a storage position, if the vehicle seat (16) is not occupied, and c) outputting a warning signal, in particular via an output device (34), if the webbing (20) is not in the storage position.

Moreover, the invention provides a seat belt system (10) for a vehicle (14) comprising an extendable seat belt (17, 18) as well as a vehicle (14) comprising a seat belt system (10).

Disclosed is a seat belt wireless communication system. The system includes a detection unit provided in each seat and detecting a first signal indicating whether or not a seat belt is fastened and a second indicating a battery state, a sub-control unit provided in the each seat and transmitting the first signal and the second signal through wireless communication; and a main control unit, performing the wireless communication with each of the sub-control units, causing the sub-control unit to wake up through the wireless communication, receiving the first signal and the second signal from the sub-control unit, determining whether or not a belt of the each seat is fastened and a charged state of a battery, and controlling an output through the first signal and the second signal.

A safety restraint system for a vehicle that includes seat belts that extend over both side pelvic portions and both side rib cage portions of the vehicle occupant and directly prevents inward and outward lateral displacement of the side pelvic portions and side rib cage portions during a side collision event. Said side belts attach to a forward-facing seat belt system with two shoulder belts, one on either side of the neck, for improved performance on the torso in a collision event, and a lap belt, while still maintaining the convenience of a single buckle click task for the occupant to secure the belt system.

A method for controlling an actuatable safety device (110) for helping to protect a vehicle occupant includes sensing left-front and right-front pressure values via a pressure tube sensor (18). The method also includes executing pressure tube metrics that evaluate the left-front and right-front pressure values and selecting switched crash thresholds in response to the pressure tube metrics. The method also includes sensing vehicle acceleration parameters (99) and executing one or more crash metrics that evaluate the vehicle acceleration parameters to determine whether the switched crash thresholds are exceeded. The method further includes controlling deployment of the actuatable safety device (110) in response to determining that the switched crash thresholds are exceeded. A vehicle safety system (100) implements the method.

Ingenious and practical, the Fire Safety Seat Belt has sensors around the car to tell the vehicle's computer to unlock the seat belts. When picking out your vehicle and wanting it fully loaded, drivers would definitely want this one extra safety mechanism, the Fire Safety Seat Belt. Not only would this device sense fires but is designed to sense the presence of excess water. This apparatus once sensing the vehicle is either on fire or flooding would release the seat belts and unlock the doors. This process would be lifesaving, allowing the individuals to easily get out of the vehicle and harm's way and to safety either by their own means or with aid of a good Samaritan. With the knowledge that you would be safe wearing your seat belt, without the potential of being stuck in the vehicle during an emergency, would also ease people's fears. Thus, this would help more individual's to make the choice to buckle up and potentially save more lives.

A method for controlling operations of safety devices of a vehicle includes determining whether there is a possibility of a collision with a preceding vehicle on the basis of vehicle driving information, determining occupancy information of a passenger or a type of a passenger or determining whether a passenger has fastened a seat belt using vehicle sensor information, and determining whether to apply, and applying accordingly, full braking, a full braking profile, or an airbag deployment scheme according to the occupancy information of a passenger, the type of the passenger, or whether the passenger has fastened a seat belt when a possibility of a collision is determined, and fully retracting the passenger's seat belt before full braking is applied after partial braking is applied.

An automatic seat belt retractor includes a belt reel configured to wind a seat belt and a sensor configured to permanently record a rotational speed of the belt reel. The sensor cooperates with an element that is speed-coupled to the belt reel to record the rotational speed. The automatic seat belt retractor includes a brake unit configured to decelerate the seat belt being unwound from the belt reel with a restraining force and a control module configured to control the brake unit with respect to the restraining force as a function of the rotational speed.
