A brushless rotary actuator comprises a housing including a motor housing defining a cavity for a motor assembly and a cover defining a cavity for a gear assembly. The motor assembly includes a rotor and a stator with a plurality of bobbins. A clip in the form of a ring plate is seated against the bobbins for retaining the bobbins on the stator. Fingers formed on the ring plate are fitted into respective slots defined by respective bobbin terminals. A circuit board is seated in the housing against an interior shoulder of the motor housing. A plate is seated in the housing against a peripheral rim of the motor housing in a spaced relationship above the circuit board.

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.

A pressure sensor for sensing a pressure level of a pressurized medium. The pressure sensor includes a housing that has a high pressure side, a low pressure side and an aperture. A substrate is located in the aperture. The substrate has a pair of ends and a center portion. The center portion is brazed to the housing in the aperture. The center portion seals the high pressure side from the low pressure side. A pressure sensitive resistor is mounted to one end of the substrate. A reference resistor is mounted to another end of the substrate. A circuit line is located on the substrate. The circuit line is connected between the pressure sensitive resistor and the reference resistor.

A seat belt tension sensor assembly is adapted to be secured to the seat belt assembly of a vehicle. The assembly includes a housing for a seat belt anchor adapted for movement relative to the housing into an overload position where a portion of the anchor is abutted against a portion of the housing to limit and arrest the movement of the anchor relative to the housing and transfer the load from the anchor to the housing and then to an interior structure of the vehicle. In one embodiment, the housing forms a collar and the anchor includes an interior wall defining an aperture through which the collar extends when the anchor is mounted to the housing. Movement of the anchor relative to the housing is limited as a result of the contact between the interior anchor wall and the collar.

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.

Tension sensing device

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.

A strain gage for measuring an applied force or weight. The strain gage includes a substrate having a tapered center section that is adapted to be stressed in response to the applied force. A strained resistor is mounted on the center section of the substrate. A wing section is attached to the center section. The wing section is adapted to be not stressed by the applied force. An unstrained resistor is mounted on the wing section. A terminal section is mounted to the center section and the wing section.

A seat belt sensor for attachment to a seat belt in a vehicle. The seat belt tension sensor has a substrate with a top surface, a bottom surface and a pair of slots therethrough. The seat belt passes through the slots. The substrate has a pair of apertures. An actuator bar is located adjacent the top surface and has a first and second end that pass through the apertures. The seat belt passes over the actuator bar. A load beam is attached to the substrate and has a first and second end. The ends of the actuator bar contact the ends of the load beam. Strain sensitive resistors are located on the load beam. The seat belt, when placed in tension, causes the actuator bar ends to flex the ends of the load beam placing stress on the strain sensitive resistor. The strain sensitive resistor generates an electrical in response to being placed under stress.

A weight sensor for measuring a weight applied to the sensor. The sensor includes a substrate that has a center section that is adapted to flex in response to the applied weight and a step section that is attached to the center section. The step section concentrates the weight onto to the center section. Strain gage resistors are mounted on the center section of the substrate for generating an electrical signal in response to the substrate being flexed. A wing section is attached to the center section. The wing section is out of the weight path and does not flex. The wing section contains signal conditioning electronics operative to condition the electrical signal.

A weight sensor for sensing an applied weight. The sensor includes a first and second outer substrate that have a first and second end and an inner surface and an outer surface. The first and second outer substrates are fixedly attached together. Several strain gauge resistors are located on the outer surfaces of the first and second outer substrates to generate an electrical signal in response to the substrate being stressed by the applied weight. The electrical signal changes as a function of the applied weight. The sensor is useful in measuring the weight of a vehicle seat occupant.

Laminated beam weight sensor

A vehicle seat weight sensor for sensing the weight of an occupant in a vehicle seat. The sensor includes a substrate that has a first and second end. The substrate is located between the seat bottom and the vehicle floor. Strain gauge resistors are located on the substrate for generating an electrical signal in response to the substrate being stressed by the weight of the seat occupant. The electrical signal changes as a function of the weight of the seat occupant. Several mounting configurations to the vehicle seat are shown.
