摘要:
A test circuit (100) for an airbag restraint system is disclosed and provides an accurate determination of the operativeness of a storage capacitor (130,132) and calculates the resistance of inertia switch resistors (114,118). The test circuit provides for parallel testing of the storage capacitor (130,132) and inertia resistors (114,118). The capacitor is tested by discharging and charging the capacitor. The values of the inertia switch resistors are determined by switching known resistive values in parallel with the inertia switch resistors. Based on the monitored voltage values during the switching, resistance values are calculated.
摘要:
Energy absorbing fabrics that are generally flat and that have a controllable and significant elongation distance. The fabrics are comprised of elongation yarns, such as partially oriented yarns (POY), and binder yarns, where the elongation yarns and the binder yarns have various weave-in percentages depending on the desired amount of elongation. In certain embodiments, because they are generally flat, the energy absorbing fabrics are suitable for use in retractors. Also provided are processes of manufacturing generally flat, energy absorbing fabrics.

Energy absorbing webbings that are generally flat and that have a controllable elongation distance are provided. The webbings are comprised of elongation yarns, such as partially oriented yarns (POY), and ground yarns. In certain embodiments, because they are generally flat, the energy absorbing webbings are suitable for use in retractors. Also provided are processes of manufacturing generally flat, energy absorbing webbings. In certain embodiments, the webbings are subjected to heat using first and second set of rollers with various feed ratios.
摘要:
An adaptive belt is attached to a vehicle seat and includes a first section (101), a second section (102), and a third section (103). The adaptive belt includes a retracted configuration and a fully extended configuration. In the retracted configuration, the adaptive belt is folded between the first section and the second section such that a first attachment attaches the first section to a first portion of the second section. In the retracted configuration, the adaptive belt is also folded between the second section and the third section such that a second attachment attaches a second portion of the second section to a first portion of the third section. In the fully extended configuration, all of the attachments fail thereby increasing a length of the adaptive belt. In response to a threshold loading condition, the adaptive belt changes from the retracted configuration to the fully extended configuration.
摘要:
An energy absorbing element for a vehicle safety belt comprising two shoulder straps, the energy absorbing element comprising a generally oblong strap component (5) connected to one of the shoulder straps (20). The oblong strap component (5) comprises two superposed length of straps joined widthwise and lengthwise together by means of seams (8). The other extremity of the oblong strap component (5) is connected to an anchoring plate or a portion (20a) of the shoulder strap by means of stitches (5e). The oblong strap component (5) also comprises an opening for receiving an arm of a plate-like component (10) connected by its other arm (10a) to another portion (20c) of the said shoulder strap. The forces suddenly applied to the shoulder strap (20) of the safety belt are transferred to the component (10) which is displaced along the strap component (5), cutting the predifined deformation seams (8) and thereby dissipating energy.
摘要:
Ein Sicherheitsgurtsystem umfaßt ein Gurtband (16), an dem örtlich ein Energieabsorptionsglied (17) vorgesehen ist, das durch einen wenigstens einfach zusammengefalteten und miteinander vernähten Gurtbandabschnitt gebildet wird. Damit der Sitzinsasse bzw. die Fachwerkstatt bereits nach einem Bagatellunfall darüber informiert ist, ob das Sicherheitsgurtsystem ausgetauscht werden muß oder nicht, ist am Gurtband benachbart dem Energieabsorptionsglied (17) eine Kennzeichnung (22) angebracht, dergestalt, daß die Kennzeichnung bei intaktem Energieabsorptionsglied für den Sitzinsassen bzw. die Fachwerkstatt unsichtbar ist (fig.2), wogegen bei zumindest teilweise aufgerissener Naht (23) die Kennzeichnung im Sichtbereich liegt.
