An escape system for a sinking car and an ultrasonic component thereof are illustrated. In the present disclosure, an ultrasonic signal transmitting unit capable of emitting ultrasonic is installed on the car. When the car falls into the water, based upon an acoustic resistance concept which the ultrasonic propagated in air collides and transmits into the water, a difference between a reflection or transmittance rate of the ultrasonic and a corresponding set value can be calculated, or alternatively, a difference between a reflection time deviation or a reflection distance of the ultrasonic and a corresponding set value can be calculated. Therefore, a warning signal indicating that the car falls into the water can be fast sent, and this makes sure that the rescue opportunity which the car falls into the water can be grasped to decrease the damage or death of the user.

Problem: To more effectively restrict movement of the airbag in an expanded and deployed state in the event of a vehicle collision, and improve the performance of restraining a passenger using an airbag. Resolution Means: A passenger restraining device of the present invention is provided with an airbag and tensile cloth. The tensile cloth is deployed to the outside of a seat by expansion and deployment of the airbag, and pulled from an upper surface of a seat back portion to a seat cushion portion. When the airbag is viewed in plan view from above during the expansion and deployment, of four regions demarcated by a first imaginary line extending in a front-rear direction of a vehicle through a center of a widest portion of the airbag on a straight line parallel to a left-right direction and a second imaginary line orthogonal to the first imaginary line and extending in the left-right direction through a center of the first imaginary line in a front-rear length of the airbag, the tension cloth passes through at least a region on an opposite side of the first imaginary line from the passenger and a vehicle front side of the second imaginary line.

A machine for folding a side curtain airbag which has a simpler machine configuration and is more efficient than a fully automatic machine and that can fold a large-capacity side curtain airbag cushion of approximately 4.0 m in length to sufficiently secure quality stability, and a process for folding a side curtain airbag by using the same, are provided.

Provided is an air-bag capable of further reducing damage value to a passenger and limiting the amount of use of inflator gas by limiting an excessive increase in the internal pressure of the air-bag upon contacting the passenger while increasing the speed of deployment in a passenger protection area. The air-bag includes a main chamber and a sub-chamber that are connected via a communication portion, wherein the communication portion or a region adjacent to the communication portion is configured of a multilayer structure portion comprising three or more layers.

An active bolster for a vehicle is provided, wherein the bolster comprises an expansible hollow interior that is inflatable and is self-supporting in both an inflated and in an uninflated position. The bolster has an inflator module for inflating the expansible hollow interior. The bolster has an inner wall for projecting inwardly into the vehicle and away from the side of the vehicle on inflation of the expansible hollow interior. The bolster may have a relatively non-expansible component located between a first expansible chamber and a second expansible chamber. The bolster may comprise an outer wall having an attachment portion for attaching the outer wall to a portion of the side of the vehicle.

A seatbelt assembly includes webbing elongated along a length, a clip slidable along the length of the webbing, an indicator extending along the length of the webbing, and a sensor coupled to the clip and sensitive to the indicator. The seatbelt assembly measures a length of a lap band stretched across an occupant. Safety features may be tailored to the body type of the occupant.
