Abstract:
An active knee bolster (28) and a knee bolster (42), whose accommodated positions are different, are mounted within an instrument panel (18) along a curved configuration of a wall portion (24) of the instrument panel (18) which, in a vehicle transverse direction, is convex and concave in a vehicle body longitudinal direction. At a time of a vehicle body collision, a main body (30) of the active knee bolster (28) moves from an accommodated position to a leg restraining position, and a leg restraining position of the active knee bolster (28) and a leg restraining position of the fixed-type knee bolster (42) become equal positions in the vehicle body longitudinal direction. In accordance with this invention, legs of an occupant can be reliably protected, and degrees of freedom in designing a vehicle interior wall such as the instrument panel or the like are improved.

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:
A pinion of a pretensioner is provided at a side of a torsion shaft, which side is opposite a side connected integrally to a spool via a sleeve. A base lock of a lock mechanism is connected to the pinion. Due to the lock mechanism operating, a leg plate side end portion of the torsion shaft is locked. In this way, due to operation of the pretensioner, the pinion, which is connected to a rotating portion of a sleeve, also is locked by the locking mechanism. Therefore, a piston of the pretensioner is not lowered, and internal pressure of a cylinder does not affect deformation of the torsion shaft.
Abstract:
A webbing retractor 10 has a structure in which a housing 48, to which a motor 44 is attached, faces in an axial direction of a worm gear 34, and is assembled and fixed to an end face of a case 30 which is orthogonal to a direction of thickness of the case 30, in which a clutch 26 which is attached in a joined state to a side face of one leg plate 16 is accommodated, and at an opposite side from a back plate 14. Moreover, this is a structure in which a rotation shaft of the motor 44 is between the leg plate 16 and a leg plate 18 in a state of being orthogonal to a winding shaft 20, and the motor 44 is disposed directly below the winding shaft 20.
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:
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.
