Abstract: An occupant sensing ECU determines an occupant state on a seat by comparing occupant determination threshold values with a corresponding sensed load data value, which is originated from load sensors. The ECU stores an adjustment value, which is used to adjust a predetermined design value of each of the occupant determination threshold values. The adjustment value is a difference between an empty-state 0 point load value and a predetermined design value of the empty-state 0 point load value.

Abstract: A polymer gel electrolyte composition includes a crosslinked polymer network matrix having a three-dimensional crosslinked structure that includes a solution of an electrolyte in a non-aqueous solvent, and a non-crosslinked polymer included within the crosslinked polymer network matrix. The non-crosslinked polymer includes (a) an ethylene unit and/or propylene unit, and (b) an unsaturated carboxylic acid unit having a carboxyl group esterified by a polyalkylene glycol having one terminal hydroxyl group protected.

Abstract: A seat occupant identifying apparatus for automotive occupant restraint system is provided which works to identify whether a seat occupant is an adult passenger or a child passenger. When a total output value of a plurality of seat load sensors is greater than a given adult identifying threshold value, it is determined that the seat occupant is an adult. Afterwards, when the total output value decreases below the adult identifying threshold value due to, for example, a lateral G-force acting on the seat occupant during cornering of the vehicle, and an output of either of the right and left seat load sensors is lowered below a preselected cornering threshold value, while the other output is higher than it, the latest determination that the seat occupant is an adult is kept as it is. This provides for high accuracy seat occupant identification during cornering of the vehicle.

Abstract: A passenger detection device for a vehicle is provided with multiple load sensors, each of which detects a load on a seat of the vehicle within a predetermined detection range of the load sensor, and an ECU that determines passenger information of the seat. The ECU has at least one calculation range, each of which limits the detection range of each corresponding one of the multiple load sensors. The ECU determines the passenger information based on a detection data value of each load sensor, which is outputted from the load sensor and falls within the corresponding calculation range of the load sensor.

Abstract: Each front sensor senses a load, which is applied to a front part of a seat, and each rear sensor senses a load, which is applied to a rear part of the seat. A size of an entire load sensing range of each front sensor is smaller than a size of an entire load sensing range of each rear sensor.

Abstract: A vehicular seat apparatus has a first slide rail unit including a first stationary rail and a first moving rail and a second slide rail unit including a second stationary rail and a second moving rail. Load sensors are provided between the seat cushion assembly and the moving rails. The first stationary rail and the second stationary rail are connected to each other by a rigid frame. The rigid frame can maintain the relative positions of the first and second slide rail units. Body mounting leg portions provided on the rigid frame are fixed to a seat mounting portion of a vehicle body.
