Abstract: The present invention is a child seat detecting apparatus for detecting the presence of a child seat in a vehicle. The child seat detecting apparatus is a tension sensing device that is attached to a vehicle seat. The tension sensing device includes a bracket that is mounted to the vehicle seat. A moveable bar is retained by the bracket. The moveable bar is attached to the child seat. A sensor is mounted between the bracket and the moveable bar. The sensor is adapted to provide an electrical signal that is indicative of a magnitude of tension on the moveable bar. A spring is located between the bracket and the moveable bar. The spring biases the moveable bar away from the bracket.

Abstract: A seat belt tension sensor for measuring the magnitude of tension in a seat belt. The seat belt tension sensor has a housing with a cavity. An anchor plate has a portion located in the cavity. The housing moves relative to the anchor plate between a first position and a second position. A sensor is mounted to the housing. The housing presses on the sensor as the housing moves from the first to the second position. The sensor generates an electrical signal in response to the housing moving between the first and second positions. The electrical signal changes as a function of tension on the seat belt. The sensor is a strain gage. The housing engages the anchor plate in the second position to protect the sensor from damage in a vehicle crash situation.

Abstract: A hall effect seat belt tension sensor for a vehicle. The sensor has a housing mounted to a seat belt. An anchor plate is mounted between the seat belt and a fixed point on a vehicle. The anchor plate is partially mounted in housing. A spring is mounted between the housing and the anchor plate. Tension on the seat belt causes the anchor plate to move relative to the housing. A magnetic field generator is mounted to the anchor plate. The magnetic field generator moves as the anchor plate moves. A magnetic field sensor is mounted to the housing. The sensor generates an electrical signal in response to movement of the magnetic field generator.

Abstract: A seat belt tension sensor is attached to a seat belt in a vehicle. The seat belt tension sensor includes a housing attached between the vehicle and the seat belt. A limit structure is located in the housing. A sensor is attached to the limit structure for generating an electrical signal in response to the sensor being placed in tension. The electrical signal changes as a function of tension on the seat belt. The limit structure moves between a first position in which the limit structure transfers the seat belt tension to the sensor and a second position in which the limit structure transfers the seat belt tension to the housing.

Abstract: A seat belt tension sensor is attached to a seat belt assembly in a vehicle. The seat belt tensor sensor is secured to the vehicle by a bolt. The sensor includes a housing that is secured by the bolt. An anchor plate is mounted to the housing. The anchor plate has a hole for the bolt and an opening. A strain gage is secured to the housing and extends into the opening. The strain gage has an aperture. A spring is located between the anchor plate and the strain gage. An actuator support is located between the spring and the strain gage to actuate the strain gage. The actuator has a projection extending through the aperture that contacts the anchor plate. The projection prevents a shift in the output of the strain gage when the sensor is subjected to mechanical shock.

Abstract: A transmission selector position sensor is designed for easy integration into a transmission assembly. The transmission selector position sensor includes a Hall effect sensor carried on a stationary member to be mounted to the transmission body and a magnetic field generator to be mounted to a rotatable member mounted to the selector shaft. The sensor assembly is made so that the stationary member carries the rotating member prior to installation in the transmission, and then is not a load bearing member after installation.

Abstract: A sensor is disclosed that fits in a compact package. This compact sensor is ideal for sensing rotary positions and for accommodating one or more potentiometers. The resistor track is parallel and opposed to the collector track, and the wiper is placed between the two tracks to swipe both of them in one embodiment. This allows a short package, because the tracks are opposed to each other rather than being in a line, and a narrow package, because the tracks are not placed side by side. Another advantage of the invention is that putting the resistor track on a larger radius and the collector track on a smaller radius allows the resistor track to be longer. Having a longer resistor track allows a higher resolution, yet a package containing the potentiometer will still be relatively small. Several potentiometers may be placed in the sensor to provide redundancy yet retain compactness.

Abstract: A position sensor according to the invention comprises a housing having an internal compartment, a terminal support web extending into the compartment, at least one terminal having a first end in contact with the terminal support web and a second end extending outwardly of the housing, a sensor element located within the internal compartment, and a connector clip. The sensor element includes a terminal portion adapted for contacting the at least one terminal. The clip comprises a bight section, at least one first finger extending from the bight section, and at least one second finger extending from the bight section opposite the first finger. The first and second fingers are adapted to receive the sensor element and the support web therebetween when the clip is installed for holding the terminal portion against the at least one terminal.

Abstract: A motor stator 400 is integrated with a position sensor 200 through a novel attachment ring 600. Electrical connection to the integrated device is through terminals 202, 210 that pass through the position sensor housing 250. The stator 400 is preferably overmolded, though other suitable forms of encapsulation are contemplated. The attachment ring 600 is preferably ultrasonically bonded to the sensor 200 during manufacture, prior to insertion of the motor armature 430. Other methods of attachment arc contemplated, and various types of motors and sensors are also contemplated.

Abstract: A position sensor for sensing the position of an attached device. There is a housing having terminals and a cover attached to the housing. Resistors, conductors and conductive traces are located on the cover and electrically connected to the terminals. A rotor is positioned between the housing and the cover, and has a contactor mounted thereon for contacting the resistor and the conductor such that as the rotor rotates a resistance value indicative of the sensor position is varied. The cover has a terminal insert which connect between the conductive traces and the terminals. A leaf spring rotates the rotor back to a starting position.

Abstract: A position sensor, in particular, a position sensor that has a modular design for easily coupling to another modular device, like a gas peddle of a vehicle. The sensor unit eliminates the use of permanently attached electrical leads or pins attached to, for example, the output pads on flexible films coupled to a rotor. In another embodiment, the sensor unit is separate from a connector unit so different connector units can each be coupled to a standard sensor unit, or the sensor unit can be coupled directly to another device, like a gas pedal, without the use of an intermediate connector unit.
