A capacitance type sensor installed in a vehicle includes the first electrode, the second electrode, and the third electrode. The first electrode is arranged inside a seating portion of a seat or a backrest portion of the seat, or both. The second electrode is arranged adjacent to the first electrode inside at least one of the seating portion and the backrest portion of the seat, whatever the first electrode is arranged. The second electrode forms an electric field together with the first electrode between them in a wetness determination mode in which a wet condition of the seat is determined. The third electrode forms an electric field together with the first and the second electrode between them in an occupant determination mode in which an occupant in the seat is determined.

Capacitance type sensor and occupant detection system having the same

A capacitance-type sensor for detecting a condition of an occupant on a vehicle seat includes an electrode. The electrode is disposed within a detection area in the vehicle seat. The electrode generates an electric field. The detection area is based on a surface pressure distribution obtained when an adult sits on the seat.

Capacitance-type sensor and occupant detection system

A seatbelt alarm device for a vehicle includes a seat sensor, a seatbelt sensor, a judgment circuit, an alarm unit, and a child seat sensor. The seat sensor detects a mass on a seat of the vehicle. The seatbelt sensor detects whether a seatbelt of the seat is engaged with a seatbelt buckle. The judgment circuit generates a demand for a seatbelt-wear alarm upon determining that a mass sits on the seat and the seatbelt is not engaged according to detection signals of the seat sensor and the seatbelt sensor, respectively. The alarm unit generates the seatbelt-wear alarm. The child seat sensor detects a child seat mounted on the seat. The judgment circuit restricts operation of the alarm unit when the judgment circuit determines that the child seat is mounted to the seat according to a detection signal of the child seat sensor.

Seatbelt alarm device for vehicle

A rotation angle detecting device includes a columnar permanent magnet that has a generally ring-shaped cross-section and a pair of magnetic poles, a pair of semi-cylindrical yokes disposed in a circumferential direction opposite the permanent magnet, a rotary shaft fixed to the permanent magnet at a shifted rotation axis and a magnetic sensor disposed in one of circumferential gaps between the yokes. The rotation axis and the magnetic poles are arranged so that the magnetic flux density becomes maximum at portions of the yoke less than 90 degrees angled from the circumferential gap in which the magnetic sensor is disposed.

Rotation angle detecting device

A vehicular occupant restraint system includes a distance sensor, an electromagnetic wave radiation-type occupant sensor, a controller, and an airbag drive circuit. When the controller predicts a collision and determines it is unavoidable based on the output of the distance sensor, the controller sends an instruction signal to the occupant sensor to determine the seating condition of an occupant. Then, the airbag drive circuit performs an airbag deployment control in accordance with the determined seating condition. This system thus reduces power consumption and electromagnetic wave radiation of the occupant sensor.

Vehicular occupant restraint system and method

A gas sensor consists of a pump cell, a monitor cell, and a sensor cell. The sensor cell is supplied with power to produce a sensor cell current. The monitor cell is supplied with power to produce a monitor cell current. A sensor cell and a monitor cell current detector are disposed between a sensor cell electrode exposed to a gas cavity and a sensor cell power supply and between a monitor cell electrode exposed to the gas cavity and a monitor cell power supply, thereby enabling the sensor cell current and the monitor cell current to be measured without addition of electric noises arising from current components flowing from the monitor cell to the sensor cell and vice versa.

Structure of gas sensor designed to minimize error of sensor output

It is the objective of this invention to reduce deviation in contact resistance variation between electrodes among pressure-sensitive resistor sensors. The sensor is composed of a pair of films. One film has a plurality of electrode portions extending in a certain direction and the other film has at least one electrode portion that is arranged in a transverse relation with a plural of the electrode portions on the other film. Contact points generated by applied pressure are limited to crossing points between the electrode portions of the pair of films. As a result, variation in contact resistance due to applied pressure shift becomes more constant. Thus, it is possible to reduce deviation of contact resistance between the electrodes among sensors.

Pressure-sensitive resistor sensor having electrodes with reduced contact resistance deviation

Gas generated from an inflator flows into a first portion of a main bag and each part of an inner bag, and the first portion is inflated toward an area in front of passenger's seat. Then, the gas filling the first portion which has been inflated flows into a second portion of the main bag. In this situation, the inflation direction of the second portion is more downward than the inflation direction of the first portion. As a result, a speed of backward inflation is decreased.

Air bag device and method for folding an air bag

An air bag device mounted in an instrument panel has an inflator for supplying gas, a bag body having a gas inlet hole, and an inner bag disposed inside of the bag body. The inner bag is formed with a pair of first through-holes and a second through-hole so that an opening area of the first through-hole is larger than that of the second through-hole. The inner bag is expanded by the gas supplied from the inflator, while a large amount of the gas is discharged from the first through-hole. Accordingly, the air bag body is expanded toward the waist of a passenger on a passenger seat. At the same time, the gas is discharged from the second through-hole to flow along an inside of a windshield, whereby the air bag can be also expanded toward the head of the passenger. As a result, even if the inflator is mounted in the instrument panel at its upper portion, the air bag device can securely protect the passenger on the passenger seat.

Air bag device having inner and outer bags for selectively directed

The present invention provides a manufacturing method for an air bag which can simply form an inner bag inside a outer bag. Cloth members of the inner bag are mounted within the outer bag and the outer bag is sewn together along its peripheries except its folded portion and a gas inlet hole for introducing gas from an inflator, by using threads. Thereafter the cloth members of the inner bag are put into the outer bag, and the cloth members of the inner bag are pulled out of the outer bag through the gas inlet hole. Thereafter, the cloth members of the inner bag are sewn together along their peripheries by using a thread. Thus, the cloth members of the inner bag are formed into a bag. Finally, putting the inner bag into the outer bag makes the air bag completed.

Manufacturing method for air bag and air bag device for a passenger

An airbag device which includes a passenger seat airbag module and driver's seat airbag module, detects a vehicle collision by means of an electronic control unit (ECU) thereof and inflates the airbags upon the vehicle collision. In the airbag device, the ECU and passenger seat airbag module are formed as a single unit which is installed in the passenger seat dashboard.

Airbag device provided with airbags located on driver's seat side and

An inflater and a control unit are integrally formed so that connector cables for electrically connecting the inflater and the control unit can be shortened to the minimum required length. In some cases, the inflater and the control unit are directly connected by soldering their terminals, and a space for disposing the connector cables is not provided in a steering wheel. Thus, the cone depth can be made as small as possible.

Air bag device having a minimized cone depth

An airbag of an airbag system is formed by sewing an edge of at least one piece of cloth two-dimensionally like a balloon. An airbag installation hole which introduces gas from an inflator into the airbag is off set from a center position of the airbag in back and forth direction of a vehicle to be away from a vehicular occupant. The airbag system is installed in an interior component of a vehicle so that the airbag inflates upwards rather than horizontally. When the airbag is inflated completely, the airbag projects towards the vehicular occupant because the airbag installation hole is formed in the off-centered position. Therefore, it is possible to fill a gap efficiency in front of the vehicular occupant with the inflated airbag and protect the vehicular occupant sufficiently.

Airbag system

An airbag safety module for automotive vehicles is provided. This module includes a box-like cover and a housing. The cover incorporates therein an airbag, an inflator, and an airbag control unit and has a plurality of openings formed in its side wall. The housing includes a base wall on which the airbag and the inflator are mounted and a side wall having thereon a plurality of protrusions engageble with the openings of the cover, respectively to complete the airbag safety module. Each of the protrusions is shaped to allow the housing to be inserted into the cover in an assembling direction of completing the airbag safety module to engage one of the openings of the cover while restricting the cover from being disengaged from the housing in a disassembling direction opposite to the assembling direction.
