A side airbag device for a rear seat relating to the technique of the present disclosure includes: an airbag module that is provided at an interior of a side garnish that is disposed between a vehicle body side portion and a vehicle transverse direction outer side of a seatback of a rear seat; a tubular flow regulating cloth that is provided at an interior of a side airbag of the airbag module, at a periphery of an inflator; and an airbag door that is provided at the side garnish, and that has a hinge portion and a tear portion at a periphery thereof, and that is pushed by the tubular flow regulating cloth when gas is generated from the inflator, wherein the tubular flow regulating cloth has openings at both ends thereof, and has exhaust holes in a peripheral wall thereof.

A method for folding a driver airbag may include: forming a tuck-in folding part by pushing an upper end portion of an airbag cushion part into the airbag cushion part; folding the tuck-in folding part toward the opposite side with respect to a driver seat; temporarily attaching the tuck-in folding part to the airbag cushion part; injecting gas into the airbag cushion part, and compressing the airbag cushion part such that the airbag cushion part maintains a plate shape; and folding the airbag cushion part while moving a folding jig disposed in a radial shape around the circumference of the airbag cushion part toward an inflator connection part.

A vehicle includes left and right front wheels, a left shock absorber, a right shock absorber, a linkage mechanism including a right side member, a left side member, a plurality of cross members, and an air bag housing case having a bottom surface and side surfaces, and housing an undeployed air bag in a housing space defined by the bottom surface and the side surfaces. The air bag housing case is located behind the linkage mechanism in a front-rear direction and below an upper end of a handlebar in a top-bottom direction, and at least partially located above a lower end of a movable region of the right side member, the left side member, and the cross members of the linkage mechanism. The bottom surface is disposed along a surface including a rear portion of the movable region when seen from a side of the vehicle.

A roof airbag apparatus may include: a gas injection unit configured to discharge gas; a tether guide extending in a longitudinal direction of a roof; and an airbag configured to be deployed by gas transferred from the gas injection unit. The airbag may include: a first chamber part coupled to the tether guide and configured to be deployed in a longitudinal direction of the tether guide by gas transferred from the gas injection unit; and a second chamber part coupled to the first chamber part, and configured to be deployed by gas transferred from the first chamber part and cover the first chamber part.

The invention relates to a one-piece woven airbag (OPW), in particular for vehicle restraint systems, with an upper fabric (OG) and a lower fabric (UG) which are joined together in a single-ply seam area (NB) forming the border of the airbag, with tether threads (TF) which are woven partially into the upper fabric (OG) and partially into the lower fabric (UG) and float there between over a defined length, which is characterised by upper limiting threads (OBF) which are woven into the upper fabric (OG) and/or lower limiting threads (UBF) which are woven into the lower fabric (UG), the limiting threads (OBF, UBF) between upper fabric (OG) and lower fabric (UG) floating over a defined number of floating tether threads (TF) and being attached to attachment points (AP) of their fabric layer (OG, UG).

A coated base fabric for an airbag has a fabric composed of polyamide fibers provided with a resin coating, wherein the polyamide fibers which compose the base fabric have a total fineness of not less than 100 dtex and not more than 250 dtex and a tenacity of not less than 8.1 cN/dtex and the coated base fabric has a basis weight of not more than 170 g/m.sup.2, packability of the base fabric in accordance with ASTM D6478-02 of not more than 1,400 cm.sup.3, a tear strength in a warp direction and a weft direction of not less than 200 N and an edgecomb resistance in the warp direction and the weft direction of not less than 200 N.

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.
