| PROBLEM TO BE SOLVED: To provide a collision detector whose working characteristics can be determined as desired. SOLUTION: A weight 3 posses an eccentricity mass 32 to determine eccentric mass moment and a metal plate 31 to determine moment of inertia without changing the eccentric mass moment. The weight 3 is supported rotatably by an axis 2 at an off-centered position against center of gravity, and is adequately set a rotation speed and frequency characteristics. A rotor 6 with a first cam 61 and a second cam 62 is fixed on the weight 3. Contact springs 4 and 5 with contacts 41 and 51 are longitudinally set on a base 8, the end of contact springs 42 and 52 apply force to the cams 61 and 62. The weight 3 is gains momentum in the b direction and contacts with inside surfaces 73 of a housing 7. When the momentum acts in the A direction, the weight 3 rotates in the a direction against the force of springs 4 and 5, contacts to a stopper 16, then rebounds and rotates in the b direction. The rotor 6 rotates with the movement of the weight 3. When the momentum of the rotor 6 reaches a specified value, a circuit between contacts 42 and 51 turns on, thereby a collision can be detected. | ||||||

| PROBLEM TO BE SOLVED: To prevent the occurrence of a fire during collision and to perform movement of a vehicle to a road shoulder by a method wherein the impact of collision is detected from the outside, and when a disconnection control signal is outputted, a source feed passage on a first load is disconnected, and a power source for a second load is fed. SOLUTION: An air bag ECU outputs an air bag operation signal SAB to the inflator of an air bag and a disconnection control unit 6. In this way, a disconnection control signal SSD is outputted to a disconnection unit. The relay circuit 5A of the disconnection unit has a normally-opening contact brought into a closed state by a disconnection control signal SSD and a first fusible link FL1 is brought into a short-circuit state. In which case, an excessive current flows to the first fusible link FL1 and the first fusible link FL1 is fused. In this case, since a minimum drive source is fed through a second fusible link FL2, a failure vehicle is moved closely to a road shoulder. COPYRIGHT: (C)1997,JPO | ||||||

| A sensor for sensing velocity changes in a motor vehicle and actuating a passenger restraint system for the deployment of an air bag includes a housing 20 containing a pair of contact blades 46, 52 and an inertia element 34 movable without substantial damping in response to a deceleration. The inertia element 34 may be biased towards a rest position by a flexible first contact blade 52 which is bent into contact with a second contact blade 46 when the inertia element 34 moves. Alternatively, the inertia element is magnetically biased to a rest position away from the contacts and completes a circuit through the contacts in response to a deceleration. The housing is mounted on a printed circuit board 84. The system includes a damped second sensor. <IMAGE> | ||||||

| PURPOSE: To miniaturize a device by biasing a moving member with a permanent magnet insert disposed along a moving path of the moving member. CONSTITUTION: A magnet 30 disposed in the axial direction of a passage path 40 of a ball 34, with an insert 28 of solid permanent magnet, biases the metal ball 34 to an end part wall 26. When a car decelerates for acceleration to exceed the force of magnetic field, the ball 34 flies out in the direction of arrow A along the path 40. When the ball 34 moves and keeps contact while bending blades 46 and 48, an electric signal is generated, and, through conductive lines 14 and 16, transferred to a system, to drive a passenger arresting device such as an air back. A speed change sensor using the ball 34 as a moving member is large in size because a large magnet is required as a path 40 exist, however, by disposing the magnet 30 in the axial direction of the path 40, miniaturization becomes possible.

| PURPOSE:To enhance the accuracy of detection of acceleration and to reduce the manufacturing cost of an acceleration sensor. CONSTITUTION:The permanent magnet 16 of a magnetic inertia body 14 for insertion into a cylinder 12 is enclosed in a metallic case 18 and a metallic plate 20 made from a gold-plated panel or a clad material of gold alloy is connected to an end face of the case 18 by welding or calking. Since the gold or gold alloy is provided only at an end face of the magnetic inertia body 14 inserted into the cylinder 12, the coefficient of friction between the magnetic inertia body 14 and the cylinder 12 is stabilized over a long period of time. Therefore, the accuracy of detection of acceleration is stabilized. Since the amount of gold used is small, the manufacturing cost of the acceleration sensor is reduced. | ||||||

| PURPOSE: To improve the degree of freedom of the layout of an impact sensing device by providing a first contact on the output member side, providing a second contact which is provided on a moving path of the first contact in the projecting direction in order to contact the first contact, and electrically connecting both the contacts to each other by the movement of the output member. CONSTITUTION: When an impact is applied in the direction of the arrow A in a state where an impact sensing device is held under the initial condition, a weight 4 is rotated and slided against a torsion spring 9 by engagement of a pinion gear 10 and a rack gear 11 to sense the impact. At this time, the engagement of a cam part 12 and an output lever 6 is released, and the output lever 6 is turned by the torsion spring 9 to bring a first contact 13 into contact with a second contact 14. Thus the electrical continuity is produced between a power supply and an ignition device for operating an air bag mechanism, and thereafter a working condition is held regardless of the position of the weight 4. As a result, the layout of the impact sensing device 2 can be freely performed with respect to the ignition device and the air bag mechanism. COPYRIGHT: (C)1993,JPO&Japio | ||||||

| PURPOSE: To adjust a fluid reducing power for meeting the desired performance after producing components of a sensor, to produce the sensor whose size is within design tolerance without restriction of level traditionally required to control the fluid reducing power for a moving piston, and to enable the sensor to be calibrated simply by changing the fluid reducing power. CONSTITUTION: A vehicle collision sensor, which operates a passenger safety device such as an airbag inflator, can be calibrated to provide the sensor with desired sensitivity to speed-reducing collision pulse of which amplitude and continuous time are different. The sensor is equipped with adjustable pieces which change the volume of controlled amount of reducing fluid, as well as piston moving distance. COPYRIGHT: (C)1992,JPO | ||||||

| PURPOSE: To form an electric passage without passing through an inertial body or the moving element of a sensor responsive to crash by providing a sensitive element moving to a second position in response to a deceleration force exceeding an actuation force. CONSTITUTION: When the deceleration force exceeds a set threshold value, it overcomes the restriction force of a field and a metal ball 34 is shifted in the direction of an arrow A along a passage 40. The metal ball 34 touches the forward end of upper contactors 50, 52 substantially simultaneously. Since the forward ends are insulated, electric contact does not take place at the moment of time. The metal ball 34 is shifted in the direction of arrow A until the contactors 50, 52 are bent in same direction to touch bends 58, 60, respectively. Consequently, an electric paths are formed between contactors 48, 50 and 46, 52. These electric paths are utilized for generation of electric signal which is delivered on conductors 14, 16, for example, to a passenger controller 80. | ||||||

| PURPOSE:To enable assembly operation to be easy by magnetizing and assembling an inertia body before forming a magnetized inertia body and then by applying magnetic field to this assembled body for magnetization. CONSTITUTION:A magnet assembly with a non-magnetized magnet element body is inserted into a cylinder to produce an assembled body 58. After that, this assembled body 58 is set to a magnetic field application device 50 which consists of a coil 52, a core 54, and a variable current DC power supply 56 and magnetic field is applied to that magnetic flux flows in a direction which is in parallel to an axial conductor of a cylindrical magnet for allowing the magnet to be magnetized and an acceleration sensor to be completed. Thus, since an inertia body before magnetization is assembled into the cylinder and the inertial body is magnetized after the entire body is completed, the inertial body is not adhered to an iron tool, a table etc. at a working site, the inertia body can be handled easily, and manufacturing operation efficiency can be improved. | ||||||

| PURPOSE: To improve the reliability with simple structure by pressing a piezoelectric element by an inertia body when an impact force is applied to the shock sensor and generating a voltage corresponding to the pressing force by the piezoelectric element. CONSTITUTION: The moment a vehicle comes into a head-on collision, the impact acceleration of the inertia body 6 increases the force pressing a pressure receiving body 4 suddenly. The force applied to the pressure receiving body 4 is transmitted to the piezoelectric element 3 through an anode plate 1d. Consequently, a peak voltage which is higher than a set value is generated by the element 3 and an inflator operating circuit detects the peak voltage to put an inflator in operation. Consequently, an air bag is expanded. Even when the vehicle has a shock from slantingly before, a component of force of shock acceleration operates on flanks formed on both sides of a perpendicular groove 4c and is transmitted to the element. Even in this case, the peak voltage larger than the set value is outputted similarly and the inflator operates to expand the air bag. COPYRIGHT: (C)1991,JPO&Japio | ||||||

| PURPOSE: To secure safety of an occupant by a sudden speed reduction of an automobile by constituting a speed change sensor of an inertia member moved by inertia force, a guiding means of the inertia member and a spring means to stop the inertia member in a constant position on the guiding means. CONSTITUTION: When an automobile is forced to perform a sudden speed reduction, a steel ball 46 is pressed under a device by sudden pressure. This force pushes a blade 22 downward, and contacts it with a blade 24. When this press is insufficient, the blade 22 is supported by the blade 24, and stops a movement of the ball 46. In the case of a strong press, since the blade 24 cannot support a press of the ball 46, the ball 46 moves up to a bottom part of a housing 18. Since pressing force of the ball 46 is reduced by resistance by such a blade 24, damage of the housing 18 by a collision is prevented. When the blades 22 and 24 contact with each other, an electric current flows to an actuator 42, and an air bag suddenly swells. | ||||||

| PURPOSE: To provide sensitive time, corresponding to deceleration by configuring a sensor capable of adjusting the initiation of an inhibit system in response to collision at a prescribed speed. CONSTITUTION: A sensor 10 is constituted of a housing 12, having an internal chamber 14 for retaining a ball 16. A head part 28 is provided on the outside of the housing 12, and a preadjustment screw 22 is provided, extending through a side wall 24, and a base end part 30 of the screw 22 is brought into contact with the ball 16 at a position of rest. By changing the weight of the ball 16 and the elastic contact of a spring piece 18, the sensor 10 is so constructed as to produce a response at the time of sensing preset deceleration. The screw 22 is adjustest with respect to the movement of the ball 16, and a detected speed of the sensor 10 is preset. Thereby, a speed of collision can be accurately preset for operating a passenger-restraining system by the sensor 10. COPYRIGHT: (C)1991,JPO | ||||||

| PURPOSE: To eliminate interference between magnetic fields and to reinforce the energizing force of a magnet by moving a sensing element at a first position that is energized by a magnet with a magnetic constraint body to a second position for establishing electrical constant according to the force of deceleration. CONSTITUTION: The sensor has a tubular body 20 made of plastic material with an extension part 24 which is hollow and a side wall 22 at one end, a metal sleeve 32 is fixed to its inner wall 30, and at the same time a recess for housing a metal ball 36 of a sensing element is formed at the side wall 22. Also, a permanent magnet 54 on the extension part 24 generates a magnetic field for energizing the ball 36 toward the side wall 22. The shape of the magnetic field is limited in the axial direction of a constraint body 56 near the tubular body 20 and its arms 58, 60 and reinforces the magnetic field of the tubular body 20. Then, a vehicle collides with an object and is rapidly decelerated in the direction of (b) while moving in the direction of (a), the ball 36 moves in the direction of a gap 38 against the energizing force of the magnet 36 and contacts contactors 44 and 46, and current is supplied from a battery 48 to a control device 50, thus expanding an air bang. | ||||||
