摘要:
A passenger protection device in a motor vehicle includes at least one airbag, at least one gas generator for filling the airbag, an airbag control device for activating the airbag, means for acquiring the deployment speed of the airbag, and means for regulating the filling quantity of the airbag, taking into account its deployment speed. In order for the passenger protection device to implement a controlled filling of the airbag dependent on its deployment speed, at least one flow-off valve is provided that is situated between the gas generator and the airbag. In addition, controllable actuating means are provided for the sealing of the flow-off valve.

A safety apparatus for a motor vehicle, comprising: a plurality of occupant protection devices and sensors associated with them; a processing device that checks whether the occupant protection devices and/or associated sensors are in operation and/or properly functional, and ascertains status information therefrom; and an output device that, in consideration of all the status information, communicates the operating status possessed by each individual occupant protection device and/or sensor. Also described is a method for communicating the status of a safety apparatus of a motor vehicle.

An occupant-protection system for vehicles, including: at least one sensor, which detects the surrounding area of the vehicle and generates sensor signals therefrom; an evaluation device, which analyzes the sensor signals, detects an approaching hazardous situation in advance according to an algorithm for the early detection of a hazardous situation and generates a trigger signal in this case; a seat-adjustment device having at least one actuator for adjusting a seat, the seat-adjustment device having a first speed for a comfort adjustment of the seat and a second, higher speed for the seating adjustment of the seat in response to triggering by the trigger signal. Also provided is a method for activating an occupant-protection system for vehicles.
摘要:
In an electronic safety device for vehicle occupants including an acceleration-sensitive sensor, a control unit, and a plurality of inertial restraining devices with associated output stages, a reliable operating mode is guaranteed for the safety device by storing characteristic fault conditions, together with control strategies compensating for these fault conditions. In the event of a fault, the safety device applies the respective, assigned control strategy to activate the restraining devices.

A restraint system is disclosed which with high reliability trips one or more restraint devices, if in a collision there is the risk of injury to vehicle occupants. This restraint system is equipped with at least one seat position senor (SPS1, SPS2, . . . , SPSm), with which a change in the seat position of at least one vehicle occupant can be ascertained, and a control unit (SE) forms a first criterion for tripping one or more restraint devices (R1, R2, . . . , Rk) if the rate of change of the seat position exceeds a predeterminable threshold. The control unit (SE) forms a second criterion for tripping one or more restraint devices (R1, R2, . . . , Rk) if one or more precrash sensors (PCS1, PCS2, . . . , PCSn) signal an incipient collision. The control unit (SE) does not cause the tripping of one or more restraint devices (R1, R2, . . . , Rk) unless both tripping criteria are satisfied and also a braking datum (BI), advantageously generated by a brake light switch, is present.

A method is used to largely suppress the offset of a rotation rate sensor in that a given rotation rate is only subjected to integration if it exceeds a lower rotation rate threshold and lies below an upper rotation rate threshold. The thresholds are predefined as a function of an offset of the rotation rate sensor in question, and integration of the rotation rate is aborted after a predefined reset time and restarted.
摘要:
So that an arrangement may decide to trigger a safety device in as error-free and reliable a manner as possible, provision is made for a first arrangement, which derives a first decision criterion for triggering a safety device from the measured turning rate at least about the longitudinal axis of the vehicle and/or from the measured accelerations at least in the direction of the transverse axis and the vertical axis of the vehicle. In addition, a second arrangement is present, which, independent of the first arrangement, derives a second decision criterion. A circuit arrangement then generates a triggering signal for the safety device, when both decision criteria are satisfied at the same time.
摘要:
To assure that the safety device is triggered at the right time in the event of a lateral collision of the vehicle with a curb, a first comparing device (1) compares a rotation rate (.omega.x) measured relative to the longitudinal axis of the vehicle, or a variable derived from this rotation rate, with a rotation rate threshold value. A second comparing device (2) compares an acceleration (ay), measured in the direction of the transverse axis of the vehicle, with a lateral acceleration threshold value. If both threshold comparing device (1, 2) simultaneously signal that their threshold values are being exceeded, a trigger signal (as1) for the safety device is output.
摘要:
A device and a method for calibrating a sensor, e.g., a force sensor such as a belt-force sensor, which allow reliable calibration of the sensor in a simple manner to counteract age-related distortion of measured values. The device for calibrating a sensor includes an arrangement for detecting at least one defined state of the sensor. When the sensor is in a defined state thusly detected, a corresponding adjustment of the measured value of the sensor may be implemented within the framework of the method.
摘要:
A belt lock (8) for receiving an attachment element (2) of a safety belt (1) has an insertion opening (10) for the attachment element (2). In the belt lock (8), a connection element (20) is provided, which penetrates a locking opening (3) on the attachment element (2). The connection element (20) is disposed on a flat spring-type carrier (17), via which an insertion movement (24) of the connection element (20) into the locking opening (3) of the attachment element (2) takes place, when the attachment element operates a locking lever (12) by its insertion movement. The insertion movement (24) of the connection element (20) is monitored via a magnetic circuit containing a magnetic field-sensing sensor (31). A component (11, 20) of the belt lock (8) that fixes the attachment element (2) of the safety belt (1) is associated with a measuring element (20), with which a force operating on the belt lock can be determined via the magnetic circuit (16, 31).
