An airbag apparatus for pedestrian protectionincluding an airbag bodydisposed along a vertical direction is disposed in an upper portionA of each of right and left front pillarsThe expansion of the airbag bodytoward the outer side of the vehicle is restrained to a predetermined amount by a clothC connecting an attachment portionA of the airbag bodywith a sewn portionB when the airbag bodyis expanded. Thus, the airbag bodyis expanded along the outer peripheral portion. In addition, a portion of the airbag bodyexpanded toward approximately the outer side in the lateral direction contacts a curved portionF expanded toward the inner side in the lateral direction, which is in a deployment portionA of a garnish panel. Thus, the airbag bodyis expanded toward approximately the inner side in the lateral direction to a large extent.

Airbag apparatus for pedestrian protection

If a control device determines that a collision during a vehicle run has been detected on the basis of a combination of an output signal of a sensor and a vehicle speed signal, an inflator is actuated so as to inflate and deploy an air bag body disposed in an apron upper member. When inflated and deployed, the air bag body raises a longitudinal-direction central portion of a hood. At this time, the longitudinal-direction central portion of the hood bends with a depression serving as an origin of bending.

Hood structure of motor vehicle

An airbag case that stores an airbag is disposed on a hood inner panel at a location close to an engine compartment. The airbag case is not fixed directly to a hood outer panel. An opening is formed in a portion of the hood outer panel located on a rear side of the airbag case as viewed in the longitudinal direction of the vehicle. In the opening, there is provided a hood garnish panel that turns over rearward upon deployment of the airbag.

A child seat (CRS) laid on a seat cushion of a front passenger seat is provided with a pair of left and right fixture attachments, which are spaced apart from each other by a predetermined distance in the direction of the width of the child seat. The fixture attachments extend rearwards from the child seat. Each of these fixture attachments is provided with a lock bar, which can be detachably coupled to a fixture bar hanging across rear portions of left and right seat cushion frames. Furthermore, there is provided a child seat detector that detects whether or not the child seat has been mounted based on movements of the lock bars resulting from coupling of the fixture attachments to the fixture bar.

Vehicular child seat detection system

An air bag apparatus for a passenger seat has reduced deploying speed and reduces the impact of the air bag on an occupant moving forward at the time of a crash of a vehicle. A gas generator is disposed in a case of the air bag apparatus, extending in a fore-to-aft direction relative to the vehicle. The gas generator case contains a cylindrical inflator extending in the fore-to-aft direction. An air bag is disposed in the apparatus case, folded in a predetermined manner. An inner bag for controlling gas flow is disposed in the air bag, folded in a predetermined manner. An auxiliary inner bag is sewed to an outside surface of a bag of the inner bag. When the inner bag is inflated and deployed, the bag of the inner bag presses a portion of the air bag against the windshield, and the auxiliary inner bag presses another portion of the air bag against the instrument panel.

Air bag apparatus for passenger seat

A seating load detecting device in which a lower arm for supporting a seat cushion and a seat back is coupled with an upper rail by a front bracket and a rear bracket. A distortion gage is attached to the bracket. The bracket comprises a curved portion of a U-shape or V-shape. The lower arm and the upper rail are coupled to each other with the direction orthogonal to two opposing legs of the curved portion being vertical. The distortion gage has a total of four distortion detecting elements G to G distributed in a matrix distribution, two attached in the front and back directional plane of the legs and two attached in the width directional plane of the legs. Due to the Wheatstone bridge connection line of these elements, high gain of a seating load detection voltage e with respect to the amount in change of the vertical load Fv can be obtained.

Seating load detecting device with bracket mounted sensor

A side airbag is housed together with an inflator containing a high pressure gas as a module in a door-side side portion of a seat. The side airbag is deployed into a space between the door and an occupant sitting in the seat, on the basis of an instruction signal from an airbag control device. An occupant sensor is disposed at a position that is located in an upper portion of a seatback of the seat and shifted from a center of the seatback with respect to directions of a width thereof toward a vehicle body center. By using the occupant sensor, it is determined whether an occupant is present at a seat of a vehicle, excluding a case where an occupant having a constitution smaller than a predetermined constitution is leaning against the side vehicle body portion. The airbag control device permits operation of the side airbag if presence of an occupant is detected by the occupant sensor. The control device prohibits operation of the side airbag if absence of an occupant is detected by the occupant sensor.

Side airbag apparatus

A seated-state detection sensor is disposed in a seat portion of a seat cushion of a passenger seat. The seated-state detection sensor is divided into three parts, that is, a first seated-state detection sensor, a second seated-state detection sensor and a third seated-state detection sensor, which are arranged in this order from the rear side of the vehicle. The first seated-state detection sensor and the second seated-state detection sensor are designed to determine whether or not there is a passenger seated. The second seated-state detection sensor and the third seated-state detection sensor are designed to detect forward displacement of the passenger.

A sensor attaching portion of an upper rail and a sensor attaching portion of a cushion frame are provided with a sensor attaching plate having a sensor disposed thereon. The upper rail and the seat cushion frame are connected with a bracket at a position facing the sensor attaching plate. When the passenger sits on the seat, the seat cushion frame moves down and a bent portion of the bracket is pressed and deformed downwards. At this time, the center in the vertical direction of the sensor attaching plate is bent outward in the lateral direction of the seat. The sensor serves to detect the generated deformation.

A beam is mounted to a mounting flange. A seat pan is mounted to opposite end portions of the beam. Provided near a middle portion of the beam is a sensor unit for detecting flexure of the middle portion of the beam. The sensor unit has a sensor beam whose length is sufficiently less than the distance between fulcrums of the beam, and a transmission member that transmits the flexure of the beam occurring at a middle point thereof to the sensor beam. The sensor beam is provided with a strain sensor.

Seat occupant detection apparatus

A sitting state detector of the present invention has an electrode which is installed in a seat back and which has a capacitance fluctuating depending on whether or not a passenger sits in a normal posture, conversion means for generating an electric signal corresponding to the capacitance, means which detects predetermined changes in the electric signal and which generates a detection signal indicative of whether or not the passenger sits in the normal posture, a sitting state sensor for a seat cushion, and control means which adjusts the conversion means for standardizing the electric signal at intervals of a short period and by a great amount in the absence of a sitting passenger and which adjusts the conversion means at intervals of a long period and by a small amount in the presence of a sitting passenger.

Sitting state detector

An air bag control system for passenger seat has a seated-state detection sensor provided in a seat, a proximity sensor that detects an object near an air bag apparatus, and an impact sensor that detects a deceleration at the time of an impact. If there is no detection made by the proximity sensor for a predetermined length of time after the seated-state detection sensor detects the seating of an occupant, a control device keeps the air bag apparatus in an operable state after elapse of the predetermined length of time. If there is no detection made by the proximity sensor for the predetermined length of time after the seated-state detection sensor makes detection, the control device ignores an on-state of the proximity sensor or a signal from the proximity sensor, and keeps the air bag apparatus in the operable state. With this control, even if a sitting adult extends his/her arm to an instrument panel after elapse of the predetermined length of time, the air bag apparatus is operated when the impact sensor detects a deceleration equal to or greater than a predetermined value.
