Abstract: The present invention relates to a knee protector structure for a vehicle. The present invention intends to make it possible to positively prevent an upper absorption bracket from being deformed with a tensile force exerted through a connecting bracket when a lower absorption bracket is deformed with knee input energy of a small-statured vehicle occupant. The knee protector structure for a vehicle according to the present invention comprises a lower absorption bracket 13 able to absorb knee input energy of a small-statured vehicle occupant, an upper absorption bracket 14 able to absorb knee input energy of a vehicle occupant of an average constitution, a connecting bracket 21 for connection between input-side end portions 18 and 20 of the lower absorption bracket 13 and the upper absorption bracket 14, and tensile force absorbing means 35 disposed near the input-side end portion 20 of the upper absorption bracket 14 and able to absorb a tensile force 34 exerted from the connecting bracket 21.

Abstract: In a vehicular air bag device which has a door member that is disposed on the rear face of an air bag lid portion, and that is pressed by an inflation pressure of an air bag body to be swung via a hinge portion, thereby forming an inflation opening in the air bag lid portion, a first hinge portion and a second hinge portion are disposed as the hinge portion. The second hinge portion is bent in a stage where the inflation pressure of the air bag body is lower than a predetermined value, to cause formation of the inflation opening to be started.

Abstract: An air bag unit includes a restrictive element, affixed within the air bag unit, which restricts lateral expansion of the air bag unit. The lateral restriction increases longitudinal expansion toward an occupant position.

Abstract: A retainer case (4) has a lower portion (4a) defining a gas diffusion chamber (5), and an upper portion (4c) cooperating with an intermediate portion (4b) to define an accommodation chamber (6), a diffuser member (15) separates the gas diffusion chamber (5) from the air bag accommodation chamber (6), with gas communication allowed therebetween through a gas inlet (16) of the diffuser member (15), an infaltor (11) is disposed in the gas diffusion chamber (5), an airbag (8) is accommodated in the accommodation chamber (6), having a retained part (8b) in a space (S1) between the intermediate portion (4b) and the diffuser member (15), and an inward projection (18) of the intermediate portion (4b) and an inward projection (17) of the diffuser member (15) constitute a gas invasion restricting structure (17+18) for restricting a gas invasion from the gas diffusion chamber (5) into the space (S1).

Abstract: A front and a back cloth body are bonded at the edges to form a bag. The bag is inflated from an air bag device disposed on a seat back so that it expands between a seat and a side door, thus protecting a passenger over a range from a torso to a head. The bag contains a supply section which holds an inflator that injects a pressurized fluid into the bag. A torso protection section, contiguous with the supply section, extends forward from the supply section. A head protection section, contiguous with the torso protection section, extends upward from the torso protection section. When the inflator is activated pressurized fluid is injected to expand head protection section. The resulting inflation pressure tends to make front side air bag pivot around the supply portion. To prevent this, in one embodiment an auxiliary section is inflated with a pressure in a direction opposite to the rotation at roughly the same time as the expansion of the head protection section.

Abstract: In order to simplify the complex setting of the expansion pressure of an inflator and easily control the expanded direction of an air bag, the air bag is contained in an instrument panel such that the air bag faces an expansion opening formed in an upper surface of the instrument panel and, when a pressure fluid discharged from the inflator is fed into the air bag through an inlet of the air bag and thereby the air bag is inflated and expanded, a front bag part for a front side of a vehicle and a rear bag part for a rear side of the vehicle are inflated and expanded forward and rearward in a vehicle longitudinal direction with the inlet therebetween, respectively. The air bag has a seam, formed in the front bag part, for temporarily delaying delivery of the pressure fluid into the front bag part during initial inflation of the air bag. Thereby, the front bag part is inflated and expanded later than the rear bag part.
