Abstract: A curtain airbag for a vehicle includes a main chamber shaped in such a way that, in the position being mounted on the vehicle, in the inflated state the main chamber covers an inner side structure of the vehicle. The curtain airbag further includes an additional chamber which, in the mounting position, is located on the in driving direction of the vehicle front portion of the main chamber, and deploys in the direction of the interior of the vehicle when the curtain airbag is inflated.

Abstract: A seat belt retractor 100 includes stop state detecting means 118 which detects that a driving signal is not inputted to power generation means 110 and drawing-direction rotation detecting means 119 which detects that the power generation means 110 is rotating in a drawing-direction of a webbing 302. Here, a control means 200 controls the power generation means 110 to rotate in the drawing direction of the webbing 302, when the stop state detecting means 118 detects that the driving signal is not inputted to the power generation means 110 and the drawing-direction rotation detecting means 119 detects that the power generation means 110 is rotating in the drawing direction of the webbing 302.

Abstract: A vehicle seat belt retractor with a belt shaft (10) and a coupled profile head lockable to a housing. A force-limiting device has at least two elements (11, 12) between profile head and belt shaft (10).

Abstract: An occupant protection device for protecting an occupant in frontal and oblique crashes. The occupant protection device operates an airbag and switches a load limiting restraint load of the seat belt between a first load limit value and a second lower load limit value. A switching unit switches the restraint load based upon the physique of the occupant, and lateral acceleration or movement of the occupant during an impact. The second load value is set for a small physique occupant. The load value is switched from the first to the second load value after a predetermined time if the lateral acceleration or occupant movement falls below predetermined levels. For a large physique occupant with lateral acceleration or movement exceeding predetermined levels, the load limiter does not switch to the second load value after the predetermined time.
