Abstract: A lining material obtained by rolling a lining material sheet into a tubular form is installed in a conduit with both ends of the lining material sheet in its circumferential direction circumferentially overlapping each other. In this process, the lining material is installed so that, in a bending portion of a conduit, an overlapping portion where the both ends of the lining material sheet overlap each other faces toward an outer curvature side of the bending portion. Then, the diameter of the lining material installed in the conduit is expanded with the both ends of the lining material sheet circumferentially slid on each other. This facilitates inflation of a portion of the lining material which portion faces toward the outer curvature side in the bending portion, thereby decreasing a gap between the lining material and an inner surface of the bending portion.

Abstract: An object of the invention is to reduce the weight of a pretensioner by reducing the length of a piston and a wire of the pretensioner. A pretensioner (1) is used in a seat belt device and pulls a seat belt. Due to gas supplied into a cylinder (10) from a gas generator (4), a piston (20) is moved in the cylinder (10). A wire (60) is connected to the piston (20) and the seat belt and pulls the seat belt when the piston (20) moves. The wire (60) has both ends that are connected to the seat belt and has a folded portion (63) that is connected to the piston (20) via connecting means (51). The connecting means (51) has a connecting hole (24) that is formed in the piston (20) and through which the folded portion (63) passes and has a detachment preventing member (52) that is positioned between the folded portion (63) and the piston (20) to prevent the folded portion (63) from being detached from the connecting hole (24).

Abstract: A side airbag device (1) protects the passenger (90) in the lateral space (92). The airbag (10) has an attaching portion (11) attached to a side section (85) of a seat (80), and is folded so as to be able to deploy from the side section (85) toward the lateral space (92). The inflator (2) generates gas and thereby deploys the airbag (10) to a leading end portion (12) in the deployment direction (F). The airbag (10) has a bellows-like folded section in which a part (30) between the leading end portion (12) and the attaching portion (11) is folded in a bellows-like shape. The bellows-like folded section is disposed in front of the attaching portion (11) in the deployment direction (F), and is folded double toward the back of the deployment direction (F) so that a portion (32) close to the attaching portion (11) is positioned therein.

Abstract: When an inner bag is inflated inside an outer bag, impact on an occupant received by an airbag is reduced. An inner bag (30) is inflated with gas supplied from an inflator (3). A gas exhaust port (31) is formed on the inner bag (30) and allows the gas to flow from the inner bag (30) in an occupant direction (E). An outer bag (20) accommodates the inner bag (30) and is inflated with the gas supplied from the gas exhaust port (31). A restriction member restricts the inflation of a portion of the inner bag (30) to change a direction of which the gas flows out from the gas exhaust port (31) to avoid the occupant direction. The restriction member breaks during the inflation of the outer bag (20) to release the restriction of the inflation of the inner bag (30).

Abstract: Included are a windup device, a screen mounted to the windup device so as to be drawn therefrom and housed therein, a stay mounted to a drawing-side edge of the screen, and a pair of arms each including a distal end portion connected to the stay so as to rotate relative thereto and a proximal end portion supported by the windup device so as to rotate relative thereto about a rotation axis, the pair of arms being configured to change a position between a folded position and an extended position through a rotary movement about the rotation axis. The pair of arms are configured such that in the extended position, one-end-side portion of a pivot base extends toward a vertical frame of a window from the rotation axis and the other-end-side portion of the pivot base and an arm part extend along the vertical frame in a manner of being bent from the distal end portion of the one-end-side portion of the pivot base, and that the arm part and the pivot base are connected so as to rotate relative thereto.

Abstract: An airbag is inflated and deployed in a short time, and a protective panel is moved rapidly. An airbag device (1) is disposed in a base section (2) of a vehicle. The airbag device (1) is provided with a protective panel (10) covering the base section (2), an airbag (20), and an inflator. The inflator inflates and deploys the airbag (20) by generating a gas. The airbag (20) has at least two standing portions (30) and inflates and deploys between the base section (2) and the protective panel (10). The standing portion (30) stands up from the base section (2) through inflation and moves the protective panel (10).

Abstract: When a gas generating member of a pretensioner mechanism is activated in case of vehicle collision, a piston inside a pipe cylinder is moved from normal state and a pinion gear body is rotated. Thus, the teeth of the pinion gear portion come in contact with a push block and pushes it in outward direction in conjunction with a force of a block urging spring, whereby a rotating lever is rotated by the push block and the lower end portion of the rotating lever gets disengaged from the tip end portion of a gear-side arm. As a result, the gear-side arm is rotated by an urging spring in outer direction and rotates a mechanical arm through a coupling shaft to make the pawl engage a ratchet gear of a take-up drum unit.

Abstract: The volume of a passenger airbag device is reduced, and the behavior thereof when inflated and deployed is stabilized. A passenger airbag device (1) installed in a top surface of an instrument panel (20) has, on an instrument panel side (back surface side) of an inflated and deployed cushion (10), a projecting portion (10b) that serves as support means when an occupant moves forward therein, and recesses (10c and 10d) provided adjacent to the projecting portion (10b). The volume of the cushion (10) is reduced by providing the recesses (10c and 10d), and the behavior of the airbag device in an inflated and deployed state is stabilized by the projecting portion (10b).

Abstract: An airbag device (1), having an airbag (10), is installed in a side wall (91) inside a vehicle cabin. The airbag (10) includes an inflatable section (30) configured to be inflated with gas and is disposed in an upper portion of the side wall (91). An inflator (2) supplies gas to the inflatable section (30), inflating and deploying the airbag (10) downward. A connecting member (50) connects the airbag (10) and the vehicle body (99) and is pulled between the vehicle body (99) and the airbag (10) that is being inflated and deployed. When the airbag (10) is inflated and deployed, a support portion (51) of the connecting member (50) supports the inflatable section (30) from the side wall (91) side of the airbag and pushes it toward the inner side of the vehicle cabin.

Abstract: In case one of three clutch pawls protrudes outwardly from the side surface of a pawl base and engages with a clutch gear and the remaining two clutch pawls are not yet engaged with the clutch gear, the peripheral portion of a deforming through hole of the clutch pawl engaging with the clutch gear is plastically deformed and the clutch pawl is deformed in a substantially L-shape while engaging with the clutch gear. Then, the pawl base can be rotated further and the remaining two clutch pawls further protrude outwardly from the side surface of the pawl base and engage with the clutch gear.

Abstract: An engagement-side flange portion, one of a pair of flange portions on the respective axial ends of a webbing-take-up portion of a take-up drum, is positioned to face engagement teeth and includes a projecting portion formed to project radially outward from its peripheral edge that faces a pawl when the pawl moves to reach engagement position with the engagement teeth. Outer peripheral diameter of engagement-side flange portion is smaller than inner peripheral diameter defined with tip ends of engagement teeth. Maximum outer peripheral dimension formed by the projecting portion and engagement-side flange portion is larger than inner peripheral diameter defined with tip ends of engagement teeth. In a state where the take-up drum is attached to a housing, the projecting portion projects radially outward over inner peripheral diameter defined with tip ends of engagement teeth that is located at axially outward side of the projecting portion.

The pair of side base fabric pieces (13) are disposed at part of side portions between the upper base fabric piece (11) and the lower base fabric piece (12) and define the shape of the air chamber (14) in an inflated state.

Abstract: An object is to prevent an airbag from bursting out toward an occupant and to inflate and deploy the airbag in a stable manner. An inner bag (30A) inflates with gas supplied from an inflator (3). An outer bag (20) inflates with the gas supplied through a flow port in the inner bag (30A). A restriction member (40A) restricts the movement of a front surface of the outer bag (20) in the occupant direction. An opening (41) in the restriction member (40A) is engaged with the outer circumference of the inflated inner bag (30A) and moves in the occupant direction along the outer circumference of the inner bag (30A) in accordance with the inflation of the outer bag (20). The restriction member (40A) moves the front surface of the outer bag (20) in accordance with the movement of the opening (41).

Abstract: A retractor includes a windup drum that winds webbing and a pretensioner unit that causes the windup drum to rotate in a windup direction of the webbing. The pretensioner unit includes a pinion gear configured to rotate in association with the windup drum, a piston that includes a rack for meshing with the pinion gear and causes the windup drum to rotate in the windup direction through the pinion gear, a tubular cylinder that has a circular cross-section and movably holds the piston, and a drive mechanism that drives the piston. The piston further includes, on a rear surface side of the rack, a contact surface configured to come into contact with an inner wall of the cylinder, and the cylinder has such a tube length as not to expose the contact portion in a movable range of the piston.

Abstract: In an airbag device to be mounted to a vehicle-body side wall, an airbag and a mounting bracket are temporarily, but securely, attached to each other, so that mounting of the airbag to the vehicle-body side wall can be easily performed. A bolt (50) is inserted through a plurality of mounting tabs (11) provided on an airbag (10) of an airbag device (1), a mounting bracket (40) having inner and outer plates (41) and (42), and an annular member (44) provided in the inner plate (41). In this state, a toothed washer (70) is fitted and temporarily attached to the bolt (50). The annular member (44) is fastened by screwing the bolt (50) into a nut (55) attached to the vehicle-body side wall (15) when the airbag (10) is mounted to a vehicle-body side wall (15).

Abstract: When a pretensioner is activated, a buckle main body experiences abrupt acceleration in a direction toward webbing. An inertial amass body of a stopper member is then rotated toward a frame member against an urging force of a torsion spring urged through a lever member. Further, the lever member abutting on the stopper member is also rotated toward the frame member, making each projecting piece face each abutment portion of a slide button. Further, when the slide button is slidingly moved against an urging force of a button spring, each abutment portion makes contact with each projecting piece of the lever member, stopping the slide movement of the slide button. Thus, unintentional disengagement between a latch and a tongue plate can be prevented.
