Abstract:
The invention relates to an integrated circuit, especially for igniting a restraint element of a car. Said circuit has a capacitor and an igniting element. A porous area (B1) of a semiconductor layer (1) forms a capacitor electrode which is separated from another semiconductor layer (3) by a dielectric layer (2), said other semiconductor layer being configured as another capacitor electrode. The other semiconductor layer (3) also has an area (J) which is tapered in its cross-section. This area serves as an igniting element (R) which is electrically connected to the capacitor (C).
Abstract:
A control apparatus for starting a safety device for the crew of a vehicle comprises a floor sensor (32) provided on a predetermined position in the vehicle for detecting the impact on the vehicle; a control section (40) for starting the safety apparatus when the calculated value based on the value detected by the floor sensor (32) exceeds a predetermined threshold; satellite sensors (30A, 30B) arranged at the front of the floor sensor (32) in the vehicle for detecting the magnitude of impact on the vehicle to determine two or more different quantities on the basis of the detected impact magnitude; and a threshold section (42) for changing threshold according to the values detected by the satellite sensors (30A, 30B).
Abstract:
The device contains a bag (41) for protecting an occupant in an automobile seat (81), a sensor (3) which recognizes the presence of an object or occupant in the danger area in which said bag (41) spreads out during inflation, and a sensor (02) for the extended belt length (GUR) of a seat belt assembly (0) assigned to the automobile seat (81). An evaluating device (5) controls the inflation of the bag (41) according to the recognition of an object or occupant in the danger area and according to the determined belt length (GUR).
Abstract:
An initiator (10) for an inflator of an automotive airbag restraint system includes a housing (12) and a wall (30) dividing the housing into two parts, one for housing a firing element (36) of the initiator, and one for receiving at least one application specific integrated circuit which performs functions of a portion of an electronic control unit. A mounting element (58) is located in the second part of the housing, and at least one application specific integrated circuit (50, 52, 56) is carried by the mounting element. The mounting element and two or more application specific integrated circuits may be provided as a package, in which at least two application specific integrated circuits are mounted in a stacked condition to form an application specific integrated circuit stack. The package includes connectors (75, 77, 79) for electrically interconnecting these predetermined electrical circuit locations in adjacent ones of the application specific integrated circuits in the stack.
Abstract:
The invention relates to a car seat (10) with a back rest (12) and an adjustable head rest (15), having a support surface (16) against which the head of the passenger can rest when restrained. The inventive device is characterized in that the head rest (15) has an expansion device which increases the size of the support area (16) of the head rest (15) when restrained. The height of the head rest (16) is adjusted in relation to the back rest (12) at least when the head rest (15) is arranged so close to the back rest (12) that the back rest (12) would prevent a full increase in the size of the support surface (16).
