A seat cushion airbag for a vehicle includes an airbag cushion that is formed with a center part installed in a center of or around a front part of a seat cushion of a vehicle and is located between legs of a passenger when being deployed. An extension part extends on both sides of the center part and is located above the legs of the passenger and an inflator is connected to the airbag cushion and provides an expansion force to the airbag cushion.

Vision-based airbag enablement may include capturing two-dimensional images of a passenger, segmenting the image, classifying the image, and determining seated height of the passenger from the image. Enabling or disabling deployment of the airbag may be controlled based at least in part upon the determined seated height.

A system and method for classifying a type of calibration or maintenance event of a phone location unit (PLU) within a defined volume, based on at least one sensor, the method comprising: determining a position of the at least one mobile communication device relative to a frame of reference of the defined volume; obtaining at least one sensor measurement related to the at least one mobile communication device, from a sensor located on at least one of: the at least one mobile communication device, within the defined volume, or outside of the defined volume; and using a computer processor to classify the type of calibration or maintenance event of the PLU, into one of a plurality of predefined types of calibration or maintenance event, based on the position and the at least one sensor measurement.

A system and method for classifying a mode of operation of a mobile communication device within a defined volume, based on multiple sensors are provided herein. The method may include the following steps: determining a position of the mobile communication device relative to a frame of reference of the defined volume, based on any of: angle of arrival, time of flight, or received intensity of radio frequency (RF) signals transmitted by the mobile communication device and received by a phone location unit located within the defined volume configured to wirelessly communicate with the at least one mobile communication device; obtaining at least one sensor measurement related to the mobile communication device from various non-RF sensors; and using a computer processor to classify the mobile communication device into one of many predefined modes of operation of the mobile communication device, based on the position and the sensor readings.

A restraint system for helping to protect an occupant of a vehicle having a floor and a cabin with a floor for the occupant includes an airbag. The airbag has a stored condition on the vehicle floor and is inflatable to a deployed condition aligned with the occupant in a forward-rearward direction of the vehicle. The airbag is configured to utilize the vehicle floor as a reaction surface for restraining the movement of the airbag in response to occupant penetration into the airbag.

For example, even when an occupant is seated offset in a left-right direction, an airbag is reliably expanded and deployed. An airbag device contains: an airbag that protects at least a side portion of a shoulder region, upper arm region, and chest region of an occupant seated on a vehicle seat; and an inflator that supplies gas to the airbag. The airbag has a pair of side part protection chambers that are housed on at least both left and right sides of the vehicle seat. The side part protection chambers, when expanded and deployed, expand and deploy forward independently from both left and right sides of the vehicle seat. A pair of the inflators are provided to allow gas to be supplied to each side part protection chamber, and the ignition timing of the inflators can be controlled separately.

A mounted object detection device includes: a load sensor in which a plurality of sensor parts each configured to detect a load are disposed in a matrix shape; and a controller configured to detect a situation of a mounted object on the load sensor on the basis of an output from the load sensor. The controller: detects a load distribution on a detection region of the load sensor on the basis of an output from the load sensor; discerns which of a person or animal and a thing the mounted object is, on the basis of the load distribution; and when having discerned that the mounted object is a thing, discerns whether or not a person or an animal is mounted on the thing, on the basis of temporal change in the load distribution.

Disclosed is a seat including: sensors which includes a first cushion sensor provided at a seat cushion in a position corresponding to buttocks of an occupant, a second cushion sensor provided at the seat cushion and located farther frontward than the first cushion sensor, a first back sensor provided at a seat back and located in a lower position thereof, and a second back sensor provided at the seat back and located above the first back sensor; and a controller connected to the sensors and thereby allowed to acquire pressure values from the respective sensors. The controller is configured to identify the motion of the occupant based on outputs of at least two sensors of the first cushion sensor, the second cushion sensor, the first back sensor, and the second back sensor.

An occupant classification system for a seat assembly. The seat assembly includes a seat cushion and a seat back. The system comprises a plurality of sensors, an algorithm, a posture classifier and a weight classification system. Each of the plurality of sensors measures a force applied to the seat cushion and/or seat back by an occupant of the seat assembly. The algorithm monitors a compensation factor and adjusts the forces measured by the plurality of sensors to compensate for the compensation factor. The posture classifier identifies a posture of the occupant based on distribution of the adjusted forces for each of the plurality of sensors. The weight classification system identifies a weight class of the occupant based on the posture and magnitude of the adjusted forces for each of the plurality of sensors.

In a vehicle, an occupant is suitably protected even when the occupant is seated in the vehicle with the seat inclined and facing a direction different from the advancing direction of the vehicle. A system for protecting an occupant boarding on a seat in a vehicle, where a seat back of the seat is configured to be inclinable with respect to a seat cushion of the seat. The system includes an acquiring unit that acquires environment information related to the vehicle in traveling or the surrounding environment thereof; and a control unit that, when the seat is facing a direction different from an advancing direction of the vehicle and the seat back is in an inclined state with respect to the seat cushion by greater than or equal to a predetermined angle, executes a support control to support the occupant in the seat to resist an inertial force that is assumed to act on the occupant boarding on the seat, based on the environment information.
