Abstract: An airbag of an airbag device for a driver seat has a front panel and a back panel. In the airbag having undergone spontaneous inflation, when a size between a securing position of the airbag to a retainer member and the most protruding portion of the airbag with respect to the securing position is set as 1, the most protruding portion by the back panel is located at a position spaced from the securing position by 0.5 or greater, a diameter of the inflated airbag of an opposing portion to an inner surface of the wheel is 0.6 to 1.2 times as large as an inner diameter of the wheel, and a diameter of the inflated airbag of a joint portion of the front panel and the back panel is greater than the diameter of the inflated airbag of the opposing portion to the inner surface of the wheel.

Abstract: A side airbag device includes an inflator and an airbag. The airbag includes a deployable bag and a separator that separates the bag into a first chamber and a second chamber. The first chamber includes a support inflation portion and a protection inflation portion. The support inflation portion is deployable in such a shape that it gradually broadens from its lower end portion toward its upper end portion along a seat-side portion. The protection inflation portion is deployable at one end side of the support inflation portion. The inflator is disposed to supply a gas into the support inflation portion. The separator includes at least one gas distribution hole in a portion thereof that separates the support inflation portion of the first chamber and the second chamber from each other. The second chamber is provided below the first chamber.

Abstract: An airbag device includes an inflator, an airbag, a holding member, and a gas rectifying member. The holding member has an opening to be formed at least when the airbag initiates to inflate. The holding member restricts the inflation of the airbag toward its outer periphery until the middle of the deployment of the airbag. The gas rectifying member restricts a flow of a gas toward an occupant and has an outlet port that discharges the gas toward the outer periphery of the airbag. When the airbag inflates, the gas rectifying member projects toward the occupant through the opening of the holding member, and the gas of the inflator causes the gas rectifying member to inflate until at least part of the outlet port is located at the occupant side beyond the opening of the holding member.

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 end lock has occurred in a seat belt retractor due to winding-up of a webbing, the end lock is easily and surely released. A stop part (6G) engages with a lock arm (40) displaced in a locking operation direction and stops the lock arm (40). A lock mechanism (9), in a state where the lock arm (40) stands still on the stop part (6G), starts operation with rotation in a pull-out direction (P) of a winding drum and stops rotation of the winding drum. A transmission mechanism (19) transmits rotation of the winding drum to the lock arm (40) and displaces the lock arm (40) in a release direction to release the engagement with the stop part (6G) is released between the time when operation of the lock mechanism (9) is started and the time when rotation of the winding drum is stopped. Release means (18) releases the engagement between the lock arm (40) and the stop part (6G) by the transmission mechanism (19).

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: 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 seat belt retractor instantly switchable between only winding of a webbing to winding and drawing-out of the webbing. Operation member 61 moves from a non-operation position E1 to an operation position E2, and locking mechanism 9 stops rotation of a winding drum in a drawing-out direction “P”. Movement member 70 moves an arrangement member 62 to a first position F1 or a second position F2, and arrangement member 62 arranges the operation member at the non-operation position E1 or the operation position E2. Urging means 63 urges the arrangement member 62 toward the first position F1. While winding a webbing 2, a second maintaining portion 77 of the movement member 70 maintains the arrangement member 62 at the second position F2. Release portion 78 of member 70 releases the arrangement member 62 toward a first portion 74, where the member 62 is kept at the first position F1.

Abstract: A lock member includes a closed cylindrical portion having lock teeth and a fixation boss provided inside the cylindrical portion and inserted in a fitting hole formed at one end of the take-up drum and facing the take-up drum along an axial direction of the cylindrical portion. A stopper mechanism includes a ring member whose inner peripheral surface is mounted on the fixation boss and whose outer peripheral surface is fitted in the fitting hole so as to prohibit relative rotation with respect to the fitting hole.

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: 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 (31) in the inner bag (30A). A connecting member (7) is disposed in the inner bag (30A) and connects an inner surface of the inner bag (30A) and a front surface of the outer bag (20). As the outer bag (20) inflates, the connecting member (7) is drawn out of the inflated inner bag (30A), moving the front surface of the outer bag (20) in the occupant direction.
