A cover body of a vehicle air bag apparatus, including a covering portion which is formed integrally with an interior panel body and which has a door portion defined by a tear seam formed in a back of the interior panel body, and, a backing portion joined to a back of the covering portion. The covering portion is made of polyolefin resin having a flexual elastic modulus of from 1500 to 3500 MPa, a tensile strength of from 17 to 40 MPa, an Izod impact strength of from 3.0 to 15.0 kJ/m2, and an elongation of 400% or less. The backing portion is made of thermoplastic olefin which is softer and has a greater elongation. The backing portion includes a reinforcing portion at a back of the door portion, a surrounding base at the back of the covering portion, and a hinge portion joining the reinforcing portion and the surrounding base.

Cover body for air bag apparatus

A cover body of a vehicle air bag apparatus, being comprised of a covering portion which is formed integrally with an interior panel body and which has a door portion defined by a tear seam formed in a back of the interior panel body, and, a backing portion joined to a back of the covering portion. The covering portion is made of polyolefin resin having a flexual elastic modulus of from 1500 to 3500 MPa, a tensile strength of from 17 to 40 MPa, an Izod impact strength of from 3.0 to 15.0 kJ/m, and an elongation of 400% or less. The backing portion is made of thermoplastic olefin which is softer and has a greater elongation. The backing portion is comprised of a reinforcing portion at a back of the door portion, a surrounding base at the back of the covering portion, and a hinge portion joining the reinforcing portion and the surrounding base.

For improving horn switch operability, an air bag apparatus supports the side wall of the cover body and is movable back and forth on the outer periphery of the surrounding wall of the base plate . Hook protrudes from the surrounding wall and is locked onto lock receiving portion of the side wall , thereby regulating the moving range of the cover body . Bracket is mounted on the under surface of the covering portion and is positioned at each of the spokes . A movable first contact is mounted on the bracket . A fixed contact support portion is provided on the outer peripheral surface of the side wall of the base plate to protrude therefrom or support in the shape of a pillar is provided integrally to protrude from the core metal of the spoke . A fixed second contact that is opposed to the movable contact is provided to oppose the movable contact

Air bag apparatus and steering wheel

The invention provides an air bag apparatus of a motor vehicle which can securely protect a passenger in a much close state by an inexpensive means. Since a rear end (a patch portion ( )) of a tether belt ( ) is positioned at a vertical surface (A) passing through a rear end ( ) of an instrument panel ( ) or in a front side thereof, in an initial expanding state of an air bag ( ), a rearward development of the air bag ( ) is restricted just before a passenger (M) due to a tension of the tether belt ( ) even in the case that the passenger (M) stands close to the instrument panel ( ), whereby no excessive impact is applied to the passenger (M).

Air bag apparatus of motor vehicle

An airbag apparatus for a vehicle has a case with an opening that is blocked by a cover that can be burst open, an airbag folded up within the case, and an inflator that ejects gas via a gas guide port into the airbag. Gas ejected from the inflator inflates the airbag inside the case, so as to burst the cover, enabling the airbag to deploy within the vehicle passenger compartment. The airbag branches at the gas guide port into a small-capacity sub-expansion part and a large-capacity main expansion part, the sub-expansion part being disposed on a front window panel side positioned at the front of the passenger compartment, and the main expansion part being positioned toward a passenger in the passenger compartment.

Airbag apparatus for vehicle

A bag-like airbag is folded into a substantially T-shape having a first developing portion which is continuous with an opening from which gas flows in and second developing portions extending fore-and-aft direction from an upper end of the first developing portion. Each of the second developing portions is folded into a bellows toward a prescribed point, thereby forming an aggregate. The aggregate is rotated, the first developing portion is wound around the aggregate, and the folded airbag is accommodated in an airbag accommodation portion of a retainer.

Airbag apparatus, folding method for airbag, and folding apparatus for airbag

The invention relates to an automotive air bag for an air bag device. This air bag in an inflated condition is generally pentahedral by the provision of a first or bottom surface, a second or upper surface, a front surface for cushioning a front passenger, and a pair of side surfaces. The first and second surfaces each extend from a first or forehand edge portion of the air bag. The first surface has (1) an opening for introducing gas into the air bag and (2) a reinforced portion surrounding the opening and adapted to be fastened to a retainer. This opening is disposed in the vicinity of the first edge portion. Thus, the air bag can efficiently be inflated.

Air bag

An air bag apparatus is provided which stably projects the air bag towards the front of a passenger. A retainer 12 stores therein an inflator 14 for injecting gas from gas injection holes at one end of the inflator, and an air bag 15 which is folded. A mid-retainer 16 is provided between inflator 14 and air bag 15. Mid-retainer 16 is provided with a plurality of guide fins 61, which are formed by making cuts in the mid-retainer and bending the cut portions. The direction of gas flow is adjusted by the inclination of each guide fin 61. The gas discharge rate is adjusted by setting various distances between each two adjacent guide fins 61 as to be greatest at the central part of the mid-retainer and either side of the center portion having a gas discharge rate approximately equal to its corresponding opposite side, thereby ensuring air bag 15 will be projected stably.

Air bag module having mid-retainer with guide fins

An airbag restraint unit for a front seat passenger aside a driver in an automotive vehicle comprises a casing having upper and lower chambers. An inflator for ejecting gas is disposed in the lower chamber of the casing. An airbag is disposed in the upper chamber of the casing to inflate and deploy upon being supplied with gas from the inflator. A mid-retainer is disposed in the casing and located between the inflator and the airbag. The casing includes a first engagement section having opposite first and second engagement surfaces inclined to gradually approach in a direction toward the airbag. First and second installation holes are formed respectively at the first and second engagement surfaces of the casing. The mid-retainer includes a second engagement section having opposite first and second engagement surfaces engaged respectively with the first and second engagement surfaces of the first engagement section of the casing. First and second fastening members are formed projecting respectively from the first and second engagement surfaces of the second engagement section of the mid-retainer. The first and second fastening members of the mid-retainer are inserted respectively into the first and second installation holes of the casing.
