A device for restraining a passenger in a relaxed position for a vehicle seat and a method for controlling the device are configured such that when a seated passenger in an autonomous vehicle enters a relaxed mode, and thus is seated in a relaxed posture in the vehicle seat, and when a vehicle speed is greater than or equal to a predetermined speed, the device automatically operates such that legs of the seated passenger can be restrained, thereby effectively protecting the passenger in the relaxed position if an accident occurs. The device includes a rod member coupled to a seat cushion and configured to have a variable length; and a support foam connected to one end of the rod member and positioned in front of the seated passenger to restrain the legs of the seated passenger.

A method for manufacturing a webbing (20) for a seat belt system in a vehicle comprises the following steps of: weaving the webbing (20) using a first yarn (30) and a second yarn (32), the first yarn (30) and the second yarn (32) reflecting light in the spectrum invisible to humans with different intensity, wherein the first and second yarns (30, 32) form a pattern (36), and overdying the webbing (20) so that the webbing (20) reflects light in the spectral range visible to humans in such a way that it has a homogenous appearance for humans. Moreover, such a webbing (20) and a vehicle comprising such a webbing (20) are provided.

An airbag deployment control apparatus for a vehicle, comprising: a first sensing unit configured to sense yaw rate information including yaw rate and acceleration values of a vehicle; a second sensing unit configured to sense whether a passenger in the vehicle wears a seat belt; a collision sensing unit configured to sense whether the vehicle collides; a communication unit configured to receive seat position information and ADAS operation information of the vehicle; and a control unit configured to calculate dynamic behavior information of the passenger and decide an airbag deployment point based on the dynamic behavior information of the passenger and the collision sensing result of the collision sensing unit.

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, receives sensor data from a plurality of sensors in an aircraft cabin; and employ an artificial intelligence (AI) program to train on input data comprising at least one of safety compliance data, aircraft system data, cabin environment data, cabin operations data, or aircraft operations data; and the AI program is configured to minimize a summed error of predictions of seatbelt compliance.
