The seat for a vehicle includes a side airbag having a head chamber. The head chamber is housed along the upper frame of the seat back. The head chamber is inflated and deployed between the shoulder belt and the head upon side impact, receiving a delivery of gases from the inflator. Here, the head chamber is configured to be housed in an inner roll folded state in which the front end of the roll folding from the front end portion in the sheet longitudinal direction is wound in a roll shape so as to be wound around the sheet outside, and the front end of the roll folding from the intermediate portion is wound in a roll shape so as to be wound around the sheet inside.

Seat for vehicle and folding method of side airbag

A vehicle seat includes a seat back, an inflator, and a side airbag. The side airbag includes a head chamber housed along an upper frame of the seat back and configured to inflate and deploy between a shoulder belt and a head in response to supply of gas from the inflator in an event of side collision. The head chamber is housed while being folded in a seat up-and-down direction to reduce a vertical width and then rolled from a front end in a seat fore-and-aft direction.

Vehicle seat and method for folding side airbag

A vehicle side airbag device including an inflator, a side airbag, and a duct is installed at a side section on a vehicle width direction outer side of a seatback of a vehicle seat configured to restrain an occupant using a three-point seatbelt. The side airbag receives a supply of gas from the inflator in a vehicle side-on collision. As a result, a waist chamber is inflated and deployed from a lower portion of the side section toward a side of a waist of the occupant, and a head chamber is inflated and deployed from an upper face side of the side section toward a side of a head of the occupant. The duct extends along a vertical direction of the side airbag inside the side airbag, and is configured to guide gas from the inflator into the waist chamber and into the head chamber.

Vehicle side airbag device and occupant protection device

A vehicle impact absorption structure includes a door trim and an impact absorption member located on an outer side of the door trim in a vehicle width direction. The impact absorption member includes a base plate arranged to face the door trim, a plurality of legs extending from the base plate toward the door trim, and a plate-shaped rigid wall extending from the base plate toward the door trim. Each of the legs is bent between a distal end of the rigid wall and the base plate.

Vehicle impact absorption structure

An assist grip includes hinges, spring cases, and coil springs. The hinges are provided with a rotary axis that a shaft-shaped protrusion and a pin make. The shaft-shaped protrusion is formed integrally with the hinges. The pin is formed independently of the hinges. The spring cases are held in a depression with which the hinges are provided, respectively. The coil springs urge the hinges by way of the spring cases in a direction for accommodating the hinges into hinge-holding depressions with which the assist grip is provided. The setup enables the resulting assist grip to offer better assemblage workability for assembly workers or robots, to show a better appearance, and to exhibit higher strength in service.

Assist grip

An assist grip of the present invention includes a grip body provided at both side base portions thereof with hinge recess portions and a hinge portion rotatably and pivotally supported in each of the hinge recess portions of both sides, and is fixed via the hinge portion to a to-be-fixed portion in an automobile. In a pivot support portion of the hinge portion, an outer support piece and an inner support piece are provided at a distance from each other, and between the inner support piece and the outer support piece, a torsion coil spring stored in a spring case is inserted. One end portion of the torsion coil spring is locked to an inside of the spring case, and the other end portion of the torsion coil spring projects from the spring case and is locked to a part of the grip body.

An assist grip includes a mounting clip formed of metal having spring resiliency and bent into a generally U shape. The mounting clip includes a pair of resilient legs. Each of the resilient legs includes a bulging portion that bulges outwardly and is provided with a retention portion to be retained by a mounting location of a vehicle body structure. Each of the resilient legs further includes at the leading end a stepped region for engagement against an inner peripheral region of a rectangular opening of a hinge body. The stepped region includes an extended region and a retaining pawl that extends outwardly relative to the extended region.

An oil seal protector for rotary engines is provided to prevent deleterious combustion gases from damaging the oil sealing assemblies provided on each side of the engine rotor. The sealing assemblies include an O-ring and the protective device comprises annular grooves which extend completely about the sealing assembly on each side of the rotor and which are located radially outwardly from such sealing assemblies. A seal ring is fitted within each of the annular grooves of the protective device and spring means are provided for urging the ring against the sides of the engine housing.

Protective device for rotary engine oil seal

An oil seal assembly is provided for a rotary engine in which an annular groove is formed in the side of the engine rotor with an oil seal ring being fitted within said annular groove. The oil seal ring is pressed against the side wall of the engine housing by annular spring means, and detent means are inserted between the ends of the annular spring means, the detent means being engaged in recesses carved in the innermost wall of the oil seal ring and in the bottom wall of the annular groove of the rotor to restrain relative motion therebetween during rotation of the rotor.
