Abstract: A pretensioner for a seat belt is configured to reduce injury by preventing load applied to the passenger's chest from increasing may include a pinion connected to a cylindrical spool wound with a webbing, a cylinder receiving a rack engaged with the pinion, a micro gas generator disposed in the cylinder and rotating the pinion by moving the rack with an explosion due to an external shock, a generator cap covering the outer circumferential edge of the cylinder and preventing the micro gas generator from separating outside, and a guide blade that guides gas discharged through vent holes to the outside is formed on the outer circumferential edge of the micro gas generator.

Abstract: A pretensioner for a seat belt is configured to reduce injury by preventing load applied to the passenger's chest from increasing, by allowing a compressed gas generated in a cylinder when a rack used for the pretensioner moves down to be discharged while rotating along a spiral guide blade formed in a micro gas generator. The pretensioner may include a pinion connected to a cylindrical spool wound with a webbing, a cylinder receiving a rack engaged with the pinion, a micro gas generator disposed in the cylinder and rotating the pinion by moving the rack with an explosion due to an external shock, and a generator cap covering the outer circumferential edge of the cylinder and preventing the micro gas generator from separating outside, in which a guide blade that guides gas discharged is formed on the outer circumferential edge of the micro gas generator.

Abstract: A system and method of detecting whether a seat belt is worn is disclosed. The system includes a contact type sensor and a non-contact type sensor installed in a seat belt buckle. A Body Control Module (BCM) receives a signal from the contact type sensor and transmitting the signal to a cluster. An airbag control unit receives a signal from the non-contact type sensor. The seat belt control unit determines whether a seat belt is worn using a signal received from the cluster when an ignition key is off, and determines whether the seat belt is worn using a signal received from the airbag control unit when the ignition key is on.

Abstract: An airbag control system for a vehicle includes: a switch, configured to be coupled to a projection on a child safety seat when the child safety seat is mounted to a vehicle seat; a tether anchor on the vehicle seat, including a contact member and a tether anchor bar configured to be coupled to a hook connected to the child safety seat, and to be electrically connected to the contact member when the tether anchor bar is not coupled to the hook; and a controller, electrically connected to the switch and the contact member. If the child safety seat is mounted to the vehicle seat and/or the tether anchor bar is coupled to the hook, the controller receives a signal from the switch and/or the tether anchor bar and instructs an airbag module not to deploy.
