Abstract:
An occupant restraint apparatus includes a shoulder anchor and an occupant restraint belt. At least a portion of the occupant restraint belt that is positioned adjacent to the occupant's head is inflatable. The occupant restraint belt comes into contact with the top edge of the seat back even when the volume of the inflatable portion is reduced. A shoulder anchor is positioned behind a seat in the front-rear direction of a vehicle at substantially the same height or below the top edge of a seat back. Therefore, a shoulder belt section of an occupant restraint apparatus extending from the shoulder anchor along the front side of an occupant is in contact with the top edge of the seat back. Therefore, when the shoulder belt section is inflated, excess inflation of the shoulder belt section toward the seat back can be prevented.
Abstract:
An airbelt apparatus including a belt guide that is capable of moving so that an expansion portion of the airbelt may expand upward alongside an occupant's head. The belt guide also limits an expanding shape of the expansion portion.
Abstract:
In a knee airbag attached to a steering column, the knee airbag is inflated and deployed quickly to a small space between an instrument panel and the knees of a vehicle occupant in a collision.A knee airbag 36 of a knee airbag device 10 is formed of a first inflation portion 38 which extends in a vehicle lateral direction along an instrument panel 12 side, and a second inflation portion 46, which is deployed to a vehicle occupant knee side. A gas supply opening 42, to which gas ejected from an inflator 22 is supplied, is disposed at a first inflation portion 38 side. The gas supply opening 42, and the pair of protection portions 46 provided at left and right end portions of knee airbag 36, are provided on substantially the same line in a vehicle lateral direction, and the first inflation portion 36 communicates the two as a gas flow path. Therefore, in a frontal collision, even if a space 48 between the instrument panel 12 and the knees of the vehicle occupant is small, the pair of protection portions 46 can be quickly inflated and deployed to the small space 48.
Abstract:
An air belt apparatus for use in a vehicle is provided to improve the comfort of the webbing during normal operation by thinning the webbing that passes through a shoulder anchor, while extending a developing length of an expanding portion upward when the expanding portion is expanded. The air belt apparatus includes webbing corresponding to the chest of an occupant, an expanding portion provided in the webbing, and folded back so as to be developed up to a position corresponding to a head of the occupant at a time of expansion, and an extending portion covering the expanding portion and extended upward from an upper end of the expanding portion, and further includes an elastic cover being expandable along the expansion of the expanding portion, and a non-extendable sheet member that enables the extending portion to pass through the shoulder anchor by reinforcing the extending portion of the elastic cover.
Abstract:
A vehicle occupant restraint system includes: a lap belt that restrains a hip of a seated occupant; a shoulder belt that has a lower end portion coupled to a middle portion of the lap belt in a seat width direction and that is used to restrain an upper body of the seated occupant; a lap belt tensioner that applies tension to the lap belt; and a shoulder belt tensioner that applies tension to the shoulder belt. When a vehicle collision is predicted or detected, the lap belt tensioner is activated before the shoulder belt tensioner is activated.
Abstract:
A vehicular occupant restraint system including: a four-point seatbelt system having left and right webbings for restraining an occupant, each of the left and right webbings having an upper body restraining portion that restrains the upper body of the occupant; a left first inflating portion which is provided on the upper body restraining portion of the left webbing and which inflates by receiving a gas supply and deploys in front of the upper body of the occupant, and a right first inflating portion which is provided on the upper body restraining portion of the right webbing and which inflates by receiving a gas supply and deploys in front of the upper body of the occupant; and a second inflating portion which inflates by receiving a gas supply when the first inflating portions inflate, and deploys to support the first inflating portions from the outside in the seat width direction.

Abstract:
A vehicle occupant restraint apparatus includes a four-point seat belt that has a pair of right and left shoulder webbings; and air belt portions that are respectively provided for the pair of right and left shoulder webbings. The air belt portions receive gas supplied from an inflator and then deploy so as to restrain a head H of an occupant P from moving forward in the vehicle longitudinal direction.
Abstract:
An occupant restraining device for a vehicle that can regulate a position of a seat belt, without occupying vehicle cabin space. An air belt device includes a retractor that is arranged to the rear, in a vehicle front-rear direction, with respect to a seat back, a seat belt that is pulled out from the retractor when applied to an occupant and that includes a shoulder belt portion for restraining an upper body of the occupant, and a belt insertion portion that is formed by indenting a portion, in a seat width direction, of an upper end of the seat back, and into which an upper side portion of the shoulder belt portion of the seat belt is made to enter.
