摘要:
A child seat(lθ) adapted for use in a vehicle, the child seat(lθ) comprising: a shell portion(38) configured for use with or without a base portion; at least one an adjustable tether(14) secured to the shell portion(38) at one end and having a clasping portion(lÌ) at the other; a tension sensor(42) for providing a signal indicative of a tension of the adjustable tehter(14); and an electronic control unit(36) secured to the shell portion(38), the electronic control unit(36) being operably coupled to the tension sensor(42) to receive the singal, the electronic control unit(36) being capable of processing the signal to compare the signal to a signal indicative of a predetermined range of acceptable tension, wherein the electronic control unit(36) provides an output indicating whether the tension of the adjustable tether(14) is within the predetermined range.

A child restraint system for transporting a child within an automotive vehicle includes a weight sensor for determining the weight of the child and compares the child's weight to a recommended weight range. The weight sensor is disposed within a cushion that lines a shell and provides an electrical signal to a control unit. The control unit processes the electrical signal and provides an alert signal when the weight is not within the recommended range. Also, the child restraint system may include a second sensor for sensing a condition that depends upon the child's weight such as directional orientation or angular orientation of the child restraint system, or location or tension of a vehicle seat belt or tether that secures the child restraint system within the vehicle, or the location or tension of a harness for restraining the child occupant within the child restraint system.

A fluid-filled seat bladder assembly (24) includes multiple capacitive sensing elements (110, 112) for detecting variation in bladder deformation due to occupant weight. The bladder (30) is defined by upper and lower elastomeric sheets (30a, 30b) that are peripherally sealed by radio frequency welding, and the capacitive sensors (110, 112) are defined by metalized films (50, 52-66/70 72) adjoining the upper and lower elastomeric sheets (30a, 30b). The bladder fluid separating the upper and lower metalized films acts as a dielectric material, and the capacitance or electric field coupling of each sensor increases when the separation between the respective upper and lower films decreases due occupant seat weight. The cumulative change in capacitance or electric field coupling reflects the total seated weight, and the individual capacitance or electric field coupling changes provide a profile of the pressure distribution across the seat for improved occupant classification. The metalized films may be located exterior of the bladder (30), or may be are formed on interior surfaces of the upper and lower elastomeric bladder sheets (30a, 30b).
摘要:
A universal, compartment-wide system identifies the presence and position of occupants of a multi-place vehicle by utilizing the occupants to conduct and radiate place-specific radio frequency signals that are received at various locations in the passenger compartment. The place-specific radio frequency signals are developed by low power transmitters disposed in the various seat/place locations, and a receiver disposed at a central location that is remote from the transmitters receives and decodes the signals radiated by the occupants to determine the number and location of the occupants. Additional receivers may be installed in specified regions to detect occupant intrusion into such regions, and in various control panels to assess driver distraction and to tailor the functional content and capability depending on whether a driver or non-driver is interacting with the control panel.
摘要:
A child restraint system and a method for monitoring installation of the child restraint system are provided. The child restraint system includes a child seat configured to receive a child occupant. The child seat has at least a first seat belt guide member configured to engage a vehicle seat belt webbing for securing the child seat to a vehicle seat. The child restraint system further includes a first sensor coupled to the first seat belt guide member. The first sensor is configured to output a first signal indicative of an amount of tension being applied to the vehicle seat belt webbing. The child restraint system further includes a controller coupled to the child seat configured to receive the first signal and to compute a first tension value based on the first signal. The controller further is configured to induce a first device disposed on the child seat to indicate when the first tension value is less than a predetermined tension value.

A child restraint system for transporting a child within an automotive vehicle includes a weight sensor(50) for determining the weight of the child and compares the child's weight to a recommended weight range. The weight sensor(50) is disoposed within a cushion(28) that hues a shell(22) and provides an electrical signal to a control unit(30). The control unit(30) processes the electrical signal and provides an alert signal when the weight is not within the recommended range. Also, the child restraint system may include a second sensor(62) for sensing a condition that depends upon the child's weight such as directional orientation or angular orientation of the child restraint system, or location or tension of a vehicle seat belt or tether that secures the child restraint system within the vehicle, or the location or tension of a harness for refraining the child occupant within the child restraint system.
摘要:
The child restraint system comprises a harness that extends through one of a plurality of slots in the shell for restraining a child occupant within the child restraint system, and a control unit for determining whether the harness is 10 properly adjusted based upon the size of the child. Belt location sensors are disposed at the slots to detect the presence of a harness belt. The child restraint system also includes temperature sensors responsive to body temperature of the child. The control unit processes the signals from the belt location sensors and the proximity sensors and issues an alert signal if the belt location is not the recommended belt location based upon the size of the child.
