摘要： In a vehicle occupant restraint system for restraining a lower part of a vehicle occupant, an arrangement for moving a restraining member (5) from a retracted position to a deployed position upon detection and/or prediction of a vehicle crash by a crash sensor (11,12) is adapted in such a manner that the restraining member cannot be made to move from the deployed position to the retracted position by an external force applied to the restraining member but can be made to move from the retracted position to the deployed position and from the deployed position back to the retracted position by a force transmitted from a power actuator (9, 15) to the restraining member via a power transmitting member (6, 7, 10). Thus, while the restraining member is capable of withstanding the load of restraining the vehicle occupant, even when the restraining member is deployed, it can be brought back to the retracted position so that the restraining system can be used repeatedly. This is particularly significant when the crash sensor includes a crash prediction sensor (12) because the prediction could be wrong and the restraining member may have to be deployed a number of times even when a vehicle crash has never occurred.

摘要： PROBLEM TO BE SOLVED: To obtain a phase shifter, capable of changing the phase of a high-frequency signal passing through an open type transmission line, even if a semiconductor element is not used and is capable of easily altering directivity in an array antenna. SOLUTION: In the phase shifter 1, a dielectric phase shifter 4 composed of a dielectric 3, having a permittivity ε larger than 1 and a drive mechanism 5, is mounted near the fixed place of the open-type transmission line 7, such as a microstrip line formed on a planar substrate 2. The phase shifter 1 is fixed onto the substrate 2 in the vicinity of the center of the transmission line 7, the dielectric 3 is driven by a moving mechanism 5, in a contacting manner to the transmission line 7 or at a fixed gap (smaller than 1 mm), the delay time of the propagated high-frequency signal is changed by making the kinds of media covering the transmission line 7 differ, and the phase between the input-output of the transmission line 7 can be altered.

摘要： PROBLEM TO BE SOLVED: To provide a weight sensor that can accurately measure weight even in the case of a sheet having a cushion spring in a cushion frame, has a simple, inexpensive control circuit, and cannot be easily affected by electromagnetic waves. SOLUTION: The weight sensor S is mounted to the cushion spring 2 that is arranged in the cushion frame 1 in the sheet, outputs the contraction/ expansion of the cushion spring 2 as a change in resistance, and comprises a first hook section 3 that is locked to the cushion spring, a second hook section 4 that is locked to the cushion frame, and a sensor section 5 that slidably supports the first hook section 3 and at the same time fixes the second hook section 4.

摘要： PROBLEM TO BE SOLVED: To provide an inexpensive weight sensor which can correctly measure crew weights. SOLUTION: A sensor unit is arranged at one peripheral wall part of opposite peripheral wall parts of a seat frame of a seat, and a converting member is attached to a rotary shaft of a rotary variable resistor of the sensor unit. A link member set extending under a seat cushion is engaged with the converting member all over the other peripheral wall part of the seat frame. The weight sensor is thus constituted. The link member detects a displacement of the seat cushion which changes downward by the crew weight, and rotates the rotary shaft of the rotary variable resistor. COPYRIGHT: (C)2003,JPO

摘要： PROBLEM TO BE SOLVED: To surely detect that a person sits on a seat for automobile within a seat member by setting a flexible foam of a polymer compound having a conductive material included therein in a plurality of positions of the seat. SOLUTION: A sitting sensor is formed of a conductive flexible foam 3 formed by mixing a conductive powder and grain 6 to a polymer compound such as rubber or polyurethane, and an upper conductor and lower conductor 5 nipping the flexible foam 3 from the upper surface and the lower surface. A plurality of such sitting sensors are distributed and arranged on an automobile seat formed of flexible foam. In such a seat, the flexible foam 3 of the sitting sensor is compressed when a pressure is added by sitting, and the electric resistance between the upper conductor 4 and the lower conductor 5 is changed. Thus, this change of electric resistance is taken as a sitting data and processed, whereby the presence of sitting can be judged.
