摘要:
A protection device for a pregnant person in a vehicle is described, a sensor being provided for detecting the pregnant person and restraint means being configured in such a way that the usability of the restraint means is influenceable as a function of a signal of the sensor. Restraint means may be disabled in the event of an accident or their deployment force may be reduced or they are usable depending on the situation.

An airbag that can be removed from its receiving shaft in the vehicle and reinserted again without any special tools is described. The airbag module (2) is provided with a locking device (8, 9, 12, 13, 14, 15) and electric contacts (23, 24, 25, 26) which cause the airbag module (2) to be mechanically locked when inserted into a receiving shaft (1) provided in the vehicle and cause an electric connection to be established between at least one ignition device (6, 7) and a controller. The locking device (8, 9, 12, 13, 14, 15) and the electric contacts (23, 24, 25, 26) are designed so that when the airbag module (2) is inserted into the receiving shaft (1), it is first locked mechanically and then the electric contact is established, and on removal of the airbag module (2) from the receiving shaft (1), the electric contact is released first and then the mechanical lock is released.
摘要:
A circuit arrangement, attainable with simple switching means, for measuring decelerations of a vehicle that, caused by a braking operation occurring before a crash, lead to a change in the seat position of the vehicle occupants, comprises measuring the deceleration with an acceleration sensor (BS), which is designed to detect high decelerations occurring in a crash, and the presence of an amplifier (OP), which amplifies the output voltage (UO) of the sensor (BS), ascribed to low decelerations, so that the digital measurement signal (MS) derived from the amplified output voltage (UOV) by an analog/digital converter (AD) has adequately high resolution of the decelerations.
摘要:
An apparatus and method for actuating a safety system for protecting an occupant of a motor vehicle measures the acceleration of the vehicle with a first sensor along a first axis oriented substantially parallel to the forward direction of motion of the vehicle. The acceleration of the vehicle is also measured with a second sensor along a second axis oriented at an angle relative to the first axis. The acceleration signal generated by the first sensor is evaluated by an analog processor and the acceleration signal generated by the second sensor is evaluated by a digital processor. The safety system is then actuated based upon both the analog and digital evaluations.
摘要:
An apparatus for tripping a system for the protection of occupants of a vehicle has a first sensor (10) for sensing the acceleration of the vehicle in its direction of forward motion and a second sensor (12) for sensing the acceleration of the vehicle in a direction transverse to its direction of forward motion. The two sensors are under the control of control devices (14,16) which trigger the occupant protection system in dependence upon the signals from the first and second sensors (10,12).

摘要:
An electronic device, in particular a system for safeguarding vehicle occupants, comprises at least two acceleration-sensitive sensors arrangements. To test the readiness for operation of the sensor arrangements, output signals from the sensor arrangements are compared. Output signals, which occur as the result of accelerations arising during normal operation of the vehicle, are also drawn upon when the comparison is made.

An air bag system is provided for use in a motor vehicle. The air bag system includes at least one air bag module. A multiple level gas generation source is coupled to the air bag module for generating a selected gas generation level applied to the air bag module. An electronic control unit controls the operation of multiple level gas generation source. At least one temperature sensor is coupled to the electronic control unit for sensing ambient temperature. At least one seat belt sensor is coupled to the electronic control unit for sensing seat belt usage. An acceleration sensor is coupled to the electronic control unit for sensing deceleration during a crash. The electronic control unit is responsive to a combination of sensed inputs from the temperature sensor, the seat belt sensor and the acceleration sensor for determining both an optimum gas generation level and inflation sequence times for controlling the multiple level gas generation source.
摘要:
A passenger safety device includes at least one electrical component, especially a restraint system such as an airbag and/or seat belt tightener, for a vehicle equipped with an electrical system, with an energy reserve circuit to temporarily maintain the voltage supply for triggering of the safety device. In order to ensure reliable functioning, it is proposed that the safety device be disconnected from the electrical system voltage (U.sub.N) when the voltage exceeds a maximum value (U.sub.max) which can be predetermined, and then be connected with the energy reserve circuit (9).
摘要:
To facilitate assembly and provide for high-level output from a deceleration sensor which provides, inherently, only very low level output, an evaluation circuit, such as an amplifier structure, is connected immediately adjacent the deceleration sensor on a common metal plate, interconnected thereby by bonding wires, the common plate having connecting pins (18) passing therethrough for connection to a standard plug-and-socket connector; the evaluation circuit and the deceleration sensor are enclosed within a common sealed housing, so that both the deceleration sensor (12, 12') as well as the evaluation circuit (16, 17) are sealed against ambient influences, preferably retained within a high-viscosity fluid, such as insulating oil. All elements can be located on one side of the housing, in which a standard T5 transistor housing is suitable; or the deceleration sensor may be located on the other side of the metal plate (10) from the evaluation circuit, in which case a plastic housing can be used, only the deceleration sensor being secured to the metal plate by a metal housing cap, sealed to the metal plate.
