Abstract: A belt retractor having an electrically actuatable locking device comprising a housing with a base plate and an upright first limb, a locking lever mounted pivotably on the upright first limb with a steel plate which is spring-loaded, and an electromagnet arranged in the housing and having a coil with a through opening, a first iron core which is arranged in the through opening, when a voltage is applied to the coil, exerts a magnetic force on the locking lever via the steel plate and actuates the locking lever for triggering a locking or unlocking movement against the force of the spring. The movement of the locking lever is enforced by a first magnetic circuit formed by the first iron core, the upright first limb and the portions of the base plate and of the locking lever between the first iron core and the upright first limb.

Abstract: PROBLEM
To provide a revolutionary airbag device that can protect an occupant's head from one side, to the front, to the other side.
RESOLUTION MEANS
The present invention is an airbag device stored in a vehicle seat, the airbag device including: an inflator for generating expansion gas; and an airbag for deploying from near an upper end of the vehicle seat to protect the periphery of the head of an occupant. Furthermore, the airbag includes: a first chamber for protecting one side of an occupant; a second chamber connected to the first chamber and for protecting the front of the occupant's head; a third chamber connected to the second chamber and for deploying from the front of the occupant's head across to the other side of the occupant; and a fourth chamber connected to the third chamber and for deploying at the other side of the occupant.

Abstract: A hanging lug for a safety airbag includes a first sewing piece, a second sewing piece, and a connecting piece. The first sewing piece and the second sewing piece are respectively provided at two ends of the connecting piece. The connecting piece is used for passing through a slit of a metal member. The connecting piece is folded in half after passing through the metal member. The first sewing piece and the second sewing piece are arranged in a staggered manner. Also provided is a safety airbag. The connecting piece is folded in half after passing through the metal member, and the first sewing piece and the second sewing piece are arranged in a staggered manner, thereby increasing the total sewing line length of the hanging lug, preventing an OPW from being damaged, reducing the number of sewn layers, and facilitating sewing operation.

Abstract: The present invention is an airbag device mounted on a steering wheel of a vehicle having a rim with a shape in which the distance from the center of rotation to the distance to the upper edges is shorter than to left and right edges, that includes a gas generator that generates an expansion gas and an airbag that expands and deploys toward the occupant due to the expansion gas. Furthermore, at the stage before the occupant comes into contact with the expanded and deployed airbag, the thickness (width) D1 of the upper end part of the airbag in the direction parallel to the rotation axis of the steering wheel when the airbag is viewed from the side is configured to be larger than the thickness (width) D2 of the lower end part.
