Abstract: By forming a resin sheet or a metal sheet, an angular-box-shaped bag main body (51) having gore portions (54) on surrounding side faces to ensure its height is formed. A folded line (55) to be folded, in a manner to form a valley line, toward an inside of the box-shaped bag main body (51) is formed in an intermediate portion of each of the gore portions (54) in a height direction. A triangular overlaid and folded portion (56) is formed in an end of each of the gore portions (54a) on each of the surrounding side faces with each corner portion of the angular-box-shaped bag main body (51) being sandwiched between one surrounding side face and another surrounding side face adjacent to the one surrounding side face in which the gore portion (54b) is folded in an overlaid manner in the overlaid and folded portion (56) at a same time when another gore portion on another surrounding side face is folded.

Abstract: A main controlling section of a controlling unit (13), when judging a collision risk, drives a motor (12) in a direction of retracting a seat belt (3) and raises tension of the seat belt (3). The main controlling section, when tension of the seat belt (3) reaches a predetermined value, judges that a locking signal is input and has the motor (12) continue retracting driving of the seat belt (3) for a predetermined time and, when a locking signal is not input, decreases a driving power of the motor (12) and lowers tension of the seat belt (3). Even when a collision risk signal is erroneously output from a collision risk judging section (11) and, so long as a locking signal is not output from the locking signal producing section (18), since control is immediately exerted so that tension of the seat belt (3) is lowered, it is possible to avoid an unpleasant feeling to a vehicle occupant (A) caused by comparative long-duration and useless restraining using the seat belt (3).

Abstract: Disclosed is a self-locking safety belt retractor comprising a blocking element which can be triggered in a belt band-sensitive and/or vehicle-sensitive manner and blocks the rotation of the belt shaft in the unwinding direction of the belt, and a tensioning drive which acts upon the belt shaft and rotates said belt shaft in the winding direction of the safety belt when being triggered. The inventive safety belt retractor is characterized by the fact that the tensioning drive which is provided with two parts (14, 15; 26, 32) that move relative to each other when said tensioning drive is triggered, is disposed on the belt shaft without being connected to the housing (10) of the belt retractor and rotates along with the belt shaft before being triggered. Furthermore, one part of the tensioning drive is fixed by means of the blocking element (17) as an abutment for the tensioning movement of the second part of the tensioning drive when the tensioning drive is triggered.

Abstract: A safety arrangement for use in a motor vehicle comprises at least one plastically-deformable element, defining an interior chamber, which will deform only when subjected to at least a first predetermined force. A source of gas is connected to inject gas into the chamber and a signal generator is provided to generate a signal representative of crash severity which is to be applied to the element during a crash situation or in an anticipated crash situation. The signal generator is connected to a control unit so as to provide the control unit with the signal. The control unit is connected to the source of gas in order to control the source of gas and to inject gas into the interior chamber of the deformable element so as to increase the gas pressure in the chamber when the crash severity signal is substantially in excess of a predetermined threshold. The arrangement provides a structure whose energy absorption characteristics can be varied according to the severity of a crash situation.
