A seat belt device 30 includes a second buckle 48 connected to a vehicle 10 side by a second webbing 49, and a tubular buckle holder 46 which is able to hold the second buckle 48 in a state in which the second buckle 48 is accommodated therein. A tongue 76 is inserted into the second buckle 48. In addition, the buckle holder 46 is provided on an anchor 32 so as to be rotatable in vehicle forward and rearward directions. Furthermore, a length dimension L1 of the second webbing 49 is set such that the second buckle 48 can be pulled out from the buckle holder 46.

A restraint system in a vehicle includes a first retractor, a second retractor, a first webbing retractably coupled to the first retractor, a second webbing retractably coupled to the second retractor, a first lower vest panel attached to the first webbing, and a second lower vest panel attached to the second webbing. The lower vest panels are inflatable and releasably attachable to each other.

A vehicle seat structure for a vehicle seat may have a structural component having an inertia belt reel. The inertia belt reel may be arranged in a cavity of the structural component, and the structural component may be connected to at least one further component of the vehicle seat structure. A method for assembling such a vehicle seat structure may include providing a structural component having an inertia belt reel and at least one further component of the vehicle seat structure that are displaced and/or rotated relative to one another such that the structural component and the at least one further component of the vehicle seat structure take up an end position with respect to one another. In a further step, the structural component and the at least one further component of the vehicle seat structure are connected to one another in a form-fitting and/or integrally bonded and/or force-fitting manner.
