Abstract: An airbag-helmet having a protective main body (10) having an inner surface pointing towards the head of the user when the helmet is worn, and an outer surface pointing away from the head of the user when the helmet is worn. Further, an inflator (40) and an airbag (30) being attached to the protective main body (10) at least indirectly and being in fluid communication to the inflator (40) are provided. The airbag (30) includes at least one tubular protection section (30a, 30b, 30c) extending from the outer surface of the protective main body (10) when the airbag (30) is filled with gas by the inflator (40).

Abstract: In an airbag system, an airbag obtained by closing each of opposite end portions of a folded metal tube with an end cap is attached to an attachment surface of a front pillar, and the airbag is deployed along the front pillar with a gas produced by an inflator. Therefore, a pedestrian who collides with the front pillar can be protected by the airbag. Since the portion of the airbag, which is away from the end cap toward an intermediate part of the airbag in a longitudinal direction of the airbag by a predetermined distance, is connected to the attachment surface, which is located outside the end cap in the longitudinal direction of the airbag, with a stay being interposed in between, the difficulty in an inflation in a part of the airbag in the vicinity of each end cap, due to the end cap being pressed against the attachment surface when the airbag is inflating, is prevented.

Abstract: The invention relates to a safety system for motor vehicles having sensor devices for detecting an accident and an apparatus for reinforcing a carrying construction (1) of a motor-vehicle roof (6), in particular the A, B or C column of the motor vehicle, which protrudes beyond a lower edge of a window opening (4), in which an inflatable reinforcing element (2) is deployed which is fastened to the carrying construction (1) and can be filled with gas via a gas generator (3) if corresponding sensor data are present. The invention also relates to a carrying construction (1) per se.

Abstract: A structure reduces impact force incurred when a structural body located forward of the vehicle interior comes toward the vehicle interior. The structure includes a pressing mechanism arranged forward of the vehicle interior. The pressing mechanism applies a pressure downwardly to the structure in order to restrict the structure from entering into the vehicle interior. The structure further includes a drive member to drive the pressing mechanism in the case of emergency.

Abstract: It is to provide a structure in which impact to the lower limbs of a vehicle occupant can be reduced effectively as compared to the prior art. A structure for reducing impact force according to the present invention is to protect an occupant in a vehicle interior, which reduces impact force, occurred when a structural body located out of and in front of the vehicle interior comes toward the vehicle interior. And the structure for reducing impact force is characterized by comprising: a pressing mechanism, which is arranged out of and in front of the vehicle interior to apply a pressure downwardly to the structure in order to restrict the structure from entering into the vehicle interior; and a drive member to drive the pressing mechanism in the case of emergency.

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.

Abstract: An air-bag (8) is mounted in the roof of a motor vehicle to be deployed in front of an occupant (7) of the vehicle. The air-bag is constrained by tear straps (15) within the air-bag to inflate initially as a “curtain” in front of the occupant of the vehicle, that curtain only having a relatively narrow thickness (t). When the tear-straps break, the bag has a more rounded configuration. The bas is releasably retained within a recess (9) which initially houses the bag. When the bag is fully inflated, the bag becomes totally separated from the recess, to prevent the bag forcing the head of the occupant rearwardly as the torso of the occupant moves forwardly during an accident.
