A motor vehicle has a passenger compartment for at least one vehicle user and has at least one sensor device for detecting a location of the vehicle user in the passenger compartment. At least one retaining device is used to fix the vehicle user in his/her location. A control device is provided to activate the at least one retaining device according to a signal of at least one impact sensor of the motor vehicle. The at least one retaining device is designed to fix the vehicle user in a location in the passenger compartment different from a vehicle seat of the motor vehicle. A method operates such a motor vehicle.

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 extendable seat belt (18) with a locking tongue (22), at least one belt buckle (24) and at least one webbing extension measuring device (30), includes the steps of: a) determining the webbing extension by means of the webbing extension measuring device (30), b) determining whether a buckling operation has occurred, c) activating at least one guide element on the belt buckle (24) and/or the seat belt (18), if a buckling operation has occurred.

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

A seatbelt detection system detects seatbelt use in each seat of a passenger aircraft to produce safety-compliance data. A computer system, which is communicatively coupled to the seatbelt detection system, generates a time-based record of the safety-compliance data. The computer system can use the time-based record to adapt cabin operations policy, including cabin temperature, cabin lighting, illumination of seatbelt signs, scheduling of meal or drink service, timing of inflight announcements, or the availability of in-flight entertainment.

An occupied seat detection device includes: at least one receiver that is disposed in a space including a plurality of seats and receives at least one of sound generated inside the space or sound generated outside the space; an acoustic characteristics analyzer that calculates, from a signal received by the at least one receiver, temporal characteristics or frequency characteristics of the sound in the space; and a detector that detects whether an occupant is present or whether an occupied seat is present inside the space, based on the temporal characteristics or the frequency characteristics calculated by the acoustic characteristics analyzer, and outputs a detection result.

A safety system for improving road compatibility of a vehicle includes a monitoring system and an integrated safety domain control unit. The monitoring system includes a vehicle external information monitoring module and a vehicle body posture monitoring module. The integrated safety domain control unit is configured to compute a collision condition between the vehicle and an obstacle based on data acquired by the vehicle external information monitoring module and the vehicle body posture monitoring module, the collision condition including a collision relative speed and a collision overlap rate, and determine, based on the collision relative speed and the collision overlap rate, whether to deploy an external airbag. A determination condition for controlling triggering of deployment of the external airbag includes determining whether the collision relative speed is less than a first speed threshold and/or whether the collision overlap rate is less than a first overlap rate threshold. The present disclosure further relates to a safety apparatus and method for improving road compatibility of a vehicle, and a medium, as well as a vehicle safety system, a vehicle safety apparatus, a method for enhancing safety of a vehicle, and a readable storage medium.

A seat for a vehicle may include a seatback including one or more inflatable bladders that may be configured to deploy in response to a triggering signal indicative of a change of velocity, collision, or predicted collision event. As at least a portion of the back of an occupant of the seat pushes against a front surface of the seatback due to the event, the one or more inflatable bladders compress at least partially the comfortable foam or comfort material in the seatback and expedite engagement of the energy absorbing material.

A method for monitoring the interior of a vehicle including emitting electromagnetic waves of at least one frequency or at least one frequency band towards at least one seat arranged in the interior of the vehicle by means of an electromagnetic radiator, receiving reflected electromagnetic waves by means of a sensor, detecting a living object on the seat from the received reflected electromagnetic waves by means of a detection device, determining a volume of the detected object from the received reflected electromagnetic waves by means of the detection device, determining a weight characteristic of the detected object on the basis of the determined volume of the object by means of the detection device, outputting a detection signal representing the weight characteristic by way of the detection device, and actuating a safety system to make the interior safe in accordance with the detection signal.

There is provided a system for improving safety of an occupant by an airbag, which can provide adaptive protection for occupants in different seat positions and different sitting postures. Further, there is provided a method for improving safety of an occupant by an airbag. Further, there is provided a computer-readable medium.
