摘要:
A side impact airbag system is disclosed that is stored behind cover panels provided on the A-hinge pillar, rocker, and C-body lock pillar. The airbag is stored in a receptacle until it is inflated by an inflator. The inflator inflates the airbag that is connected between fore-and-aft spaced anchoring points. When the airbag is in a deployed position, it is located between a seat and door of the vehicle. The deployment height of the airbag is controlled by tethering side shield panels that are secured between the airbag and the vehicle. The tethering side shield panels are not inflated by the inflator but are pulled to a taut condition as a result of the deployment of the airbag.
摘要:
A method and system for modeling an inflatable supplemental restraint device for a vehicle includes operating a simulation system according to a first step in which the restraint device is modeled in a fully inflated configuration using a finite element model. The modeled airbag is then deflated and flattened. The flattened airbag is subjected to simulated folding using a finite element model. Inputs drawn from the results of successive portions of the simulation are used in the later modeling steps.

A method for rollover sensing (12) that may be used in the determination of when to deploy restraints in a vehicle is disclosed herein. The method for rollover sensing (12) may include lateral acceleration sensors (22), a roll rate sensor (18), and a roll angle detector (20). A control circuit (16) determines a roll moment of inertia as a function of lateral acceleration, a trip point length as a function of the lateral acceleration, and a trip point angle as a function of the lateral acceleration. The control circuit (16) also determines a rollover threshold in response to a roll rate signal, a roll angle signal, the trip point length, the roll moment of inertia, and the trip point angle. The control circuit (16) further generates a control signal for a deployment circuit in response to the rollover threshold.

Intelligent vehicle rollover detection systems and methods are claimed and described. An embodiment may comprise various data sensors to sense various signals and a control circuit to receive the signals. In some embodiments, the control circuit may be adapted to provide a vehicle unstable signal to activate a first occupant restraint system and a rollover detection signal to activate a second occupant restraint system. In some embodiments, the control circuit may also determine an updated threshold and a reduced threshold, and generate a rollover detection signal in response to at least one of the updated threshold and a reduced threshold. Other embodiments are also claimed and described.
摘要:
A roof support for a vehicle is provided containing a first side roof rail; a transverse roof bow fixed to and extending from the first side roof rail; and a first brace fixed to the first side roof rail at a forward point on the first side roof rail, wherein the first brace extends to the transverse roof bow and is fixed to a first aft point on the transverse roof bow, thereby advantageously defining a first angle between the first side roof rail and the first brace. The roof support may further include a second side roof rail opposite the first side roof rail such that the roof bow laterally extends from the first side roof rail to the second side roof rail, wherein a second brace is connected in like manner.

A rollover sensing system (12) that may be used in the determination of when to deploy restraints in the vehicle. The rollover sensing system (12) may include lateral acceleration sensors (32), a roll rate sensor (18) and a roll angle detector (20). A control circuit (16) determines a predetermined rollover threshold in response to the roll rate and roll angle detector (20) and calculates an adjusted threshold as a function of the predetermined rollover threshold and the lateral acceleration. The control circuit (16) generates a control signal in response to the adjusted threshold.
