The acceleration sensors in the air bag unit are made up of a plurality of acceleration sensors of different kinds. The air bag unit is disposed on a steering wheel and each of the acceleration sensors is disposed such that the direction of movement of a movable element to be provided in each of the acceleration sensors is parallel to an axis of rotation of the steering wheel. The inflator is electrically ignited and each of the acceleration sensors controls the electric current supply to the inflator.
42 Tilt switch responsive to acceleration or deceleration US847750 1992-03-05 US5256839A 1993-10-26 Shawn Gallagher
An economical and accurate tilt switch, which incorporates a reed switch, a small disc shaped magnet, and an enclosed track in which the magnet is allowed to roll just enough to affect the contacts of the reed switch. Invented to replace the well known mercury switch, but avoid the environmental hazards of mercury poisoning. The present tilt switch can be adapted into many different designs providing a wider range of switching characteristics than that of the old mercury switch.
43 Gas damped crash sensor US635764 1990-12-28 US5237134A 1993-08-17 Torbjorn Thuen; Harald S. Husby; Allen K. Breed
Conventional ball-in-tube, gas-damped, crash sensors utilize a gold plated ball to bridge two contacts. When the ball senses acceleration (deceleration) in the longitudinal direction of a cylinder of sufficient magnitude and duration, it moves to where it bridges the contacts, completing the electrical circuit and initiating deployment of a safety restraint system. A switch activated by magnetic flux is combined with this type of gas-damped sensor to provide a solid and reliable contact duration and ensure the correct functioning of the sensor. The level of biasing force for crash zone crash sensors of this type has been increased to avoid late firing problems on marginal crashes.
44 Actuator for use in emergency situation of vehicle US684177 1991-04-12 US5217252A 1993-06-08 Teruhiko Kawaguchi; Keiichi Tamura; Hisahiro Ando; Tamotsu Horiba; Kenichi Kinoshita
An actuator for use in an air bag device which is inflated by a gas as a firing pin is moved by the movement of an inertia member to actuate a gas generator and in a preloader of a webbing retractor actuated by the gas. A contact is provided for outputting an electrical signal by being turned on at the time of movement of the inertia member or movement of the firing pin. Accordingly, by providing another gas generating means adapted to be actuated in correspondence with an output of this contact, it is possible to actuate a plurality of air bag devices or preloaders.
45 Extended minimum dwell shock sensor US745205 1991-08-14 US5212357A 1993-05-18 Daniel R. Reneau
A shock sensor achieving the advantages of extended minimum dwell and extended total dwell employs a reed switch in a housing mounted coaxial to the reed switch. The shock sensor employs a magnet of cylindrical shape, which is coaxial with the reed switch and slidably mounted to activate the reed switch. The shape of the activation magnet, which also serves as an acceleration detecting mass, is that of a cylindrical shell which extends along the axis of the reed switch. The shell has a ring portion extending radially inward and of short axial extent on the end of the magnet which lags in activation. A spring extends between an abutment and the magnet within the shell. When the shock sensor is subjected to an acceleration, the magnet is moved by the acceleration force from a non-activating position. Further extending the activation dwell time of the sensor and, in addition, providing an extended minimum dwell time, is the shape of the magnetic field created by the ring at the first abutting end of the magnet.
46 Impact sensor US427087 1989-10-23 US5028750A 1991-07-02 Hans Spies; Alfons Woehrl; Horst Laucht
A magnetic impact sensor for motor vehicles with a safety system such as an airbag or belt tensioner for an occupant restraint system, has a circuit breaker arranged in an electrical trigger circuit of the safety system for inflating the airbag or tightening the belt by closing the trigger circuit in response to an acceleration or deceleration effective beyond a prescribed time duration. For this purpose a magnet in combination with specially shaped pole pieces forms two magnetic circuits the magnetic conductances of which are influenced by the position of a ferromagnetic ball that moves in response to an impact relative to the pole pieces to thereby open or close the circuit breaker. Normally, in the absence of an impact the ball is in a first position that keeps the circuit breaker open. When an impact occurs the ball moves into a second position to close the circuit breaker and thus the trigger circuit.
47 Velocity change sensors US454674 1989-12-21 US5010216A 1991-04-23 Michael R. Sewell; Allan W. DeJong
Various embodiments of sensors are disclosed which contain an inertial mass that is magnetically biased to an initial position. In response to a certain deceleration, the mass is caused to swing about an axis and operate a switch. In some embodiments, the switch is one that is held open by the inertial mass' presence in its initial position and closes when the inertial mass swings away from its initial position, while in other embodiments it is one whose contacts are bridged by a conductive portion of the inertial mass only after the inertial mass has been displaced from its initial position, while in still other embodiments it is a reed switch that is magnetically operated. Motion of the inertial mass can be undampened or dampened. If dampening is desired, it can be accomplished either pneumatically or electromagnetically.
48 Force responsive switch US525172 1983-08-23 US4518835A 1985-05-21 Francis Grossar
In response to a deceleration force, a rapidly reacting magnetic system causes a reed switch to change state. A predetermined time after the force ceases, a second, relatively slowly reacting magnetic system causes the switch to return to its original state. Each magnetic system includes a fixed magnet and a magnet movable within a recess. The reed switch is situated in a housing proximate the recesses and is controlled by the positions of the movable magnets. The recess through which the movable magnet of the slowly reacting system moves contains a fluid. This magnet carries a pair of self-positioning members which cooperate with the fluid to regulate the speed of the movement of the magnet within the recess, in accordance with its direction of movement, such that the slowly reacting system maintains the switch in the changed state and, thereafter, returns the switch to its original state.
49 Acceleration switch with magnetic permeable metal sleeve for shunting magnetic field US3737599D 1971-10-26 US3737599A 1973-06-05 ZUVELA B
An acceleration switch utilizes a permanent magnet with a pole enclosing a magnetically permeable shield and a magnetically permeable ball. The field of the magnet is normally shunted by the shield and ball to weaken the magnetic field existing at a magnetic reed switch. In response to the acceleration, the ball leaves the sleeve and diminishes the shunting effect of the sleeve, so that the field at the reed switch increases and actuates the switch. Directional sensitivity of the acceleration switch is provided by the shape of the cavity within which the ball moves. A winding may be provided about the reed switch for testing switch operation or selectively inhibiting the actuation of the switch.

PURPOSE: A shock sensor is provided to extend the closure duration and increase the reliability. CONSTITUTION: A shock sensor (20) having some structural similarities to a reed switch, particularly in the use of a glass capsule (22) which hermetically seals the components of the shock sensor. The shock sensor employs a sensing mass (31) mounted on a metallic planar spring (32). Under the influence of a crash-induced acceleration, the sensing mass is driven against a fixed contact to close an electrical circuit. The contact surface (40) which is formed on the sensing mass is oriented at an angle of 60 degrees out of the plane containing the spring.
53 SENSORS FOR DETECTING RAPID DECELERATION/ACCELERATION EVENTS US13170079 2011-06-27 US20120326422A1 2012-12-27 Andre Baca
Sensors for detecting rapid deceleration/acceleration events are disclosed herein. A sensor configured in accordance with one embodiment of the disclosure includes a magnetically operable device proximate to a magnet. The sensor also includes a biasing member operably coupled to a magnetic shield. The biasing member controls the movement of the magnetic shield between a first position that shields the magnetically operable device from the magnet, and a second position that exposes the magnetically operable device to the magnet. In a deceleration/acceleration event, the magnetic shield overcomes the biasing member and moves from the first position to the second position, thereby causing the magnetically operable device to be exposed to the magnet.
54 Acceleration detector and passive safety device US10806152 2004-03-23 US20040174006A1 2004-09-09 Toshiyuki Yamashita
By using an acceleration detector 51 incorporating mass members respectively capable of detecting impact acceleration applied from different directions, the impact acceleration applied on the vehicle from the different directions is detected with one acceleration detector. The installation space of the acceleration detector in a car compartment sensor unit 6 is reduced. Moreover, the increases in costs and weight are suppressed.
55 Miniature acceleration sensor US10113572 2002-04-02 US06550306B1 2003-04-22 Martyn Bensley
An upper housing is ultrasonically welded to a lower housing forming a hermetic seal about two opposed ferromagnetic leads extending from a reed switch. A shock sensing magnet has a cylindrical bore and is spring biased within the housing to slide along the glass capsule of the reed switch in response to acceleration. The magnet functions as a shock sensing mass, and is shaped to increase the reed switch dwell time. The reed switch leads are bent to extend downwardly along the sides of the housing and are bent horizontally to be parallel to the housing sides and a circuit board. A strip of mu-metal wraps three sides of the housing and has tabs extending partly beneath the housing for soldering to the circuit board. The magnet and the housing are constructed from plastics which can withstand momentary high temperature associated with a re-flow solder process.

58 Acceleration detection device and sensitivity setting method therefor US09931046 2001-08-17 US20020056622A1 2002-05-16 Toshiyuki Yamashita; Eiichiro Murai
The setting of a sensitivity of an acceleration detection device is performed by regulating the characteristics of a compression coil spring such as an initial load or a spring constant of the compression coil spring and by regulating the dimension of a mass body in an axial direction of a slide shaft. Further, a compression coil spring is used which has non-linear deflection-load characteristics.
59 Shock sensor employing a spring coil for self-test US09860908 2001-05-18 US06335498B1 2002-01-01 Philip James; Martyn John Bensley
A reed switch based shock sensor provides for passing electrical current through the coil spring used to bias the shock sensing magnetic mass. The spring is wrapped around the reed switch, allowing the coil spring to act as an electrical coil. The coil generates a magnetic field of sufficient strength to cause the reed switch reeds to attract and so close the reed switch, thus allowing the reed switch to be tested without the addition of a test coil.
60 Reed switch with shock sensing mass within the glass capsule US09860888 2001-05-18 US06329618B1 2001-12-11 Philip James; Anthony Howell
A shock sensor has a shock sensing magnetic mass that rides on the inside of a glass tube that is sealed about a reed switch. The reed switch has a first stop positioned so that the shock sensing magnetic mass when resting against the first stop does not cause the reeds of the reed switch to attract. A spring extends between the shock sensing magnetic mass and a second stop. Acceleration causes the sensing mass to accelerate toward the second stop. The motion of the magnetic sensing mass causes the switch reeds to attract and close the reed switch. The entire shock sensing mechanism is hermetically sealed within the glass capsule of the reed switch. The reed switch within the glass capsule detects movement of the shock sensing mass.
