Abstract: A curtain air bag device which allows a bag main body to expansively spread more quickly and reliably. A curtain air bag device comprises a bag main body received inside a head lining disposed on the window upper edge of a vehicle and designed to expansively spread from the lower end of the head lining toward the interior of the vehicle at the time of actuation; and a gas supply device for supplying expansion gas to the bag main body. The bag main body has a plurality of chambers which expand during operation; and a duct extending above the chambers along the window upper edge to distribute the gas to respective chambers. Further, the duct has an expansion region where the lower end is disposed lower than the lower end of the head lining during spreading.

Abstract: A two stage-ignition air bag apparatus for a vehicle of the present invention includes an air bag, a first inflator ignited when a value according to collision severity has reached a first threshold value in order to inflate the air bag, and a second inflator ignited at earlier one of times when the value according to collision severity has substantially reached a second threshold value that is greater than the first threshold value and when a predetermined time has passed since the value according to collision severity reached the first threshold value in order to inflate the air bag.

Abstract: A seat pressure sensor unit of the present invention is provided at a portion receiving a pressure of a seat. The sensor unit comprises a sensor provided on a top face of a base cloth and a heater wire provided on the top face of the base cloth not so as to overlap the sensor.

Abstract: A safety system includes a seatbelt apparatus for supporting a shoulder of a vehicle occupant, an airbag apparatus having an airbag body, and control means for controlling a sealing member. The airbag body is inflated to receive the occupant by gas introduced into the airbag body. The airbag body has first and second ports for exhausting the gas. The sealing member is disposed on the second exhaust port. The sealing member is set to either one of a first state where the gas is prevented from being exhausted from the second exhaust port and a second state where the gas is allowed to be exhausted. The sealing member is ordinarily set to the first state. The seatbelt apparatus outputs a seatbelt apparatus application signal to the control means when the seatbelt apparatus is applied to the occupant. The control means set the sealing means to the second state when the control means receives the seatbelt apparatus application signal.

Abstract: An air bag apparatus for a vehicle has a longitudinal pad, a longitudinal metal cover, and an air bag that is folded-up. The pad is fixed within a roof rail, and has a cross-section that is substantially the shape of a hat that protrudes into the passenger compartment of the vehicle. The cover is disposed beneath the pad on the inner surface of the roof rail, has an upper end that is fixed to the uppermost surface of the pad, a lower end that is in proximity to the roof rail, and a substantially L-shaped cross-section. The air bag is housed between the roof rail and the cover and, when the vehicle experiences a collision, pushes outward between the lower end of the cover and the roof rail, so as to form an aperture therebetween, from which the air bag deploys downward.

Abstract: A metal case consists of a inner case and an outer case, the inner case and the outer case have respective rear surface portions which are mutually separated but overlapped on a back side of the metal case, an inflator has fitting bolts which penetrate the rear surface portions of the inner case, the inflator secured to the rear surface portion of the inner case by fitting bolts and nuts, and top ends of the fitting bolts are covered with the rear surface portion of the outer case. Accordingly, even when a passenger pushes or touches a seat back above the fitting bolts, he or she feels smooth or pleasant to the touch.

Abstract: In order to reinforce the opening of an air bag container against excessive deformation, laterally extending ribs of beads are formed on the upper and lower surfaces of the container. Vertically extending connection flanges which are arranged on the inboard edges of the container are arranged to be merged and/or rigidly connected with the ribs. Openings in the flanges through which bolts are disposed are arranged proximate the ribs.

Abstract: A meter driving device for indicating angular positions corresponding to input values. The device includes a memory for storing previously given input values, angular directions corresponding to the input values, and coefficients representative of the grades of change in angular direction depending on the change between adjacent two input values, as parameters. Based on these parameters and the frequency of input pulse signal giving the input values, the angular direction corresponding thereto is calculated. The angular direction signal receives PWM process and then supplies to a pair of crossed exciting coils via a driver. During a predetermined time period from the turning ON and OFF of the power source, the transference of the angular direction signals to the driver is shut out by logic gates, thereby inhibiting malfunctional meter indication.

Abstract: A knee protective panel of a vehicle, extending laterally of the vehicle in front of a driver's seat under an instrument panel and having a U-shaped cut receiving a steering column is provided with a reinforcing member fixed to the protective panel so that there is formed between the protective panel and reinforcing member an enclosed space extending laterally immediately under the U-shaped cut. In one embodiment of the invention, an opening is formed in an outboard half of the reinforcing member lying on the outboard side of the steering column so that the rigidity of the outboard half is made lower than that of the inboard half.

Abstract: In an automotive seat assembly including an operating lever device operative to permit a seat back to be inclined forwardly or backwardly, the operating lever device is provided with means for preventing any part thereof from being projected out of the back or front face of the seat back when the latter is inclined forwardly or backwardly.

Abstract: A device for purifying sewage by employing a bed of aerobes or activated sludge characterized by the use of a movable air supply means which is moved across the bottom portion of the bed to apply a concentrated supply of air to a limited portion of the bed to effect air washing of the bed and also applies the air washing to the entire bed in a predetermined period of time.
