Abstract:
Es wird eine Vorrichtung zur Seitenaufprallerkennung bzw. ein Drucksensor (25) vorgeschlagen, wobei dem Drucksensor (25) als Plausibilitätssensor ein mechanischer Schalter (24) zugeordnet ist. Dieser mechanische Schalter (24) ist vorzugsweise im Gehäuse des Drucksensor (25) angeordnet.
Abstract:
Die Erfindung betrifft einen als Achsträger ausgebildeten Hilfsrahmen (1) für ein Fahrzeug, der zwei Längsträger (2) sowie eine zwischen den beiden Längsträgern (2) angeordnete Versteifungsstruktur (3) aufweist, wobei die Längsträger (2) im Wesentlichen als Hohlprofil ausgeführt sind und mindestens eine Sollknickstelle (18, 19) in Form einer in Längserstreckungsrichtung der Längsträger (2) verlaufenden Krümmung aufweisen. Um diesen Hilfsrahmen (1) dahingehend zu verbessern, dass dieser einerseits gute mechanische Eigenschaften wie Festigkeit, Steifigkeit, Akustik und Versteifung der Karosserie im Fahrbetrieb sicherstellt und andererseits ausreichend Verformungsenergie im Crashfall aufnimmt und dabei dennoch mit einem geringen Bauteilgewicht und gleichzeitig einfach und kostengünstig herstellbar ist, weisen die Längsträger (2) im Bereich der Sollknickstelle (18, 19) mindestens eine etwa in Längserstreckungsrichtung der Längsträger (2) verlaufende Sicke (16, 17) auf.
Abstract:
Overlapping section (81) is constructed by positioning an inner side wall portion (78) of an outer impact absorbing section (63) closer to a longitudinal centerline (48) of a vehicle body than an outer side wall (33, 103) of a front side frame (11, 12; 91), so that a collision impact load can be transmitted to the outer side wall portion by way of the overlapping section. Inner impact absorbing section (62) projects forward by a greater length than an outer impact absorbing section (63). Thus, an airbag- deploying acceleration threshold value Gs is set within a range between an acceleration level when the inner impact absorbing section (62) alone is deformed by impact energy and an acceleration level when the inner and outer impact absorbing sections (62, 63) are deformed.
Abstract:
A collision type identifying device is disposed in a central portion of a vehicle main body and has first deceleration detecting means (22), peak time detecting means (32), required time detecting means (34), and type identifying means (36). The deceleration detecting means (22) detects a vehicle deceleration in the longitudinal direction. The peak time detecting means (32) detects, as a first peak time (tp), a time from the excess of a preset threshold (GTH) by a waveform of the vehicle deceleration (G) detected by the deceleration detecting means (22) to a first peak. The required time detecting means (34) detects, as a required time (tn), a time when an integrated deceleration (VG) obtained through time quadrature of the vehicle deceleration (G) becomes equal to a predetermined integrated value set in advance. The type identifying means (36; 78) identifies a vehicle collision type on the basis of the first peak time (tp) and the required time (tn). The collision type identifying device can identify a vehicle collision as one of a plurality of collision types at once.
Abstract:
The invention relates to a method for generating a triggering signal for a passenger protection device consisting in determining and evaluating data of sensors for setting a collision classification. A device for carrying out the inventive method is also disclosed. Said method consists in evaluating signals (a(10), a(12), a(14)) received from at least two measuring points (10', 12', 14') remote from each other at a predetermined distance (d) in a direction x in order to determine a relative collision speed (v rel ), and in determining a time interval (?t) between the detected crash signal detected by the first sensor (10', 12', 14') at a first measuring point (10', 12', 14') and the crash signal detected by the second sensor (10, 12, 14) at a second measuring point (10', 12', 14').
Abstract:
The invention relates to a method for limiting damages in the event of a partially overlapping frontal collision of two motor vehicles according to which a signal that reports the beginning of a collision or a collision shortly before occurring initiates an inward turning of the steerable front wheels (9, 10) whereby the wheel plane (34) of the collision-side wheel (9) intersects the vertical longitudinal central plane (33) of the vehicle at a point (36) situated in front of the vehicle. To this end, a connecting element (17) with means (24) for rapidly reducing pressure is provided in the steering device (13-16), whereby the connecting element (17) acts upon the steering device (13-16) in the event of a collision so that at least the collision-side front wheel (9) is turned inward in the positive sense.
Abstract:
A curtain airbag (10A - 10F) for a vehicle (2) has an inflatable cushion. The cushion (10A - 10F) has one or more side inflatable portions extending along one side of the interior of the vehicle (2) adjacent the interior door or doors on the one side and an inflatable frontal portion (12) projecting inwardly directionally toward the interior of the vehicle positioned in front of a seated occupant (1) and between the occupant (1) and an instrument panel or dash of the vehicle. Preferably, the inflatable frontal portion (12) is positioned between the occupant (1) and the steering wheel (4) wherein the frontal portion (12) laterally juts into the passenger compartment forming an inflatable barrier between a front pillar (60) of the vehicle (2) and the occupant (1).
